ADAPTIVE CRUISE CONTROL (ACC) — IF EQUIPPED

Adaptive Cruise Control (ACC) increases the driving convenience provided by cruise control while traveling on highways and major roadways. However, it is not a safety system and not designed to prevent collisions. Speed Control function performs differently. Please refer to the proper section within this chapter.

ACC will allow you to keep cruise control

engaged in light to moderate traffic conditions 5

without the constant need to reset your cruise control. ACC utilizes a radar sensor and a forward facing camera designed to detect a vehicle directly ahead of you.

    If the sensor does not detect a vehicle ahead of you, ACC will maintain a fixed set speed.
    If the ACC sensor detects a vehicle ahead, ACC will apply limited braking or accelerate (not to exceed the original set speed) auto- matically to maintain a preset following distance, while matching the speed of the vehicle ahead.

The Cruise Control system has two control modes:

    Adaptive Cruise Control mode for main- taining an appropriate distance between vehicles.
    Normal (Fixed Speed) Cruise Control mode for cruising at a constant preset speed. For additional information, refer to“Normal (Fixed Speed) Cruise Control Mode” in this section.

Normal (Fixed Speed) Cruise Control will not react to preceding vehicles. Always be aware of the mode selected.

You can change the mode by using the Cruise Control buttons. The two control modes function differently. Always confirm which mode is selected.

ADAPTIVE CRUISE CONTROL (ACC) OPERATION

The Speed Control buttons (located on the right side of the steering wheel) operate the Adaptive Cruise Control (ACC) system.

Adaptive Cruise Control Buttons

    — CANC/Cancel
    — Normal (Fixed Speed) Cruise Control On/Off 3 — Adaptive Cruise Control (ACC) On/Off

4 — Distance Setting Decrease 5 — SET (+)/Accel

6 — RES/Resume 7 — SET (-)/Decel

8 — Distance Setting Increase

Any chassis / suspension or tire size modifica- tions to the vehicle will affect the performance of the Adaptive Cruise Control and Forward Collision Warning system.

ACTIVATING ADAPTIVE CRUISE CONTROL (ACC)

You can only engage ACC if the vehicle speed is above 0 mph (0 km/h).

The minimum set speed for the ACC system is

20 mph (32 km/h). 5

When the system is turned on and in the ready state, the instrument cluster displays“ACC Ready.”

When the system is off, the instrument cluster displays“Adaptive Cruise Control (ACC) Off.”

You cannot engage ACC under the following conditions:

    When you apply the brakes.
    When the parking brake is applied.
    When the automatic transmission is in PARK, REVERSE or NEUTRAL.
    When the vehicle speed is outside of the speed range.
    When the brakes are overheated.
    When the driver’s door is open at low speeds.
    When the driver’s seat belt is unbuckled at low speeds.
    Electronic Stability Control (ESC) Full Off mode is active.

Push and release the Adaptive Cruise Control (ACC) on/off button. The ACC menu in the instrument cluster displays“ACC Ready.”

Adaptive Cruise Control Ready

To turn the system off, push and release the Adaptive Cruise Control (ACC) on/off button again. At this time, the system will turn off and the instrument cluster displays“Adaptive Cruise Control (ACC) Off.”

Adaptive Cruise Control Off

TO SET A DESIRED ACC SPEED

When the vehicle reaches the speed desired, push the SET (+) button or the SET (-) button and release. The instrument cluster display will display the set speed.

If the system is set when the vehicle speed is below 20 mph (32 km/h), the set speed shall be defaulted to 20 mph (32 km/h). If the system is set when the vehicle speed is above 20 mph (32 km/h), the set speed shall be the current speed of the vehicle.

ACC cannot be set if there is a stationary vehicle in front of your vehicle in close proximity.

Remove your foot from the accelerator pedal. If you do not, the vehicle may continue to accelerate beyond the set speed. If this occurs:

    The message“DRIVER OVERRIDE” will display in the instrument cluster display.
    The system will not be controlling the distance between your vehicle and the vehicle ahead. The vehicle speed will only be determined by the position of the accelerator pedal.

TO CANCEL

The following conditions cancel the system:

    The brake pedal is applied.
    The CANC button is pushed.
    An Anti-Lock Brake System (ABS) event occurs.

    The Electronic Stability Control/Traction Control System (ESC/TCS) activates.
    The vehicle parking brake is applied.
    Driver seat belt is unbuckled at low speeds.
    Driver door is opened at low speeds.
    The driver switches ESC to Full Off mode. NOTE:

If your vehicle stays at standstill for longer than two seconds, then the system will cancel and the brake force will be ramped-out. The driver will have to apply the brakes to keep the vehicle at a standstill.

TO TURN OFF

The system will turn off and clear the set speed in memory if:

TO RESUME

If there is a set speed in memory push the RES (resume) button and then remove your foot from the accelerator pedal. The instrument cluster display will display the last set speed.

ACC cannot be resumed if there is a stationary vehicle in front of your vehicle in close proximity.

The Resume function should only be used if 5

traffic and road conditions permit. Resuming a set speed that is too high or too low for prevailing traffic and road conditions could cause the vehicle to accelerate or decelerate too sharply for safe operation. Failure to follow these warnings can result in a collision and death or serious personal injury.

    The gear selector is removed from the DRIVE position.
    The Adaptive Cruise Control (ACC) on/off

button is pushed.

TO VARY THE ACC SPEED

    The Normal (Fixed Speed) Cruise Control on/
    The braking temperature exceeds normal range (overheated).

off button is pushed.

    The ignition is placed in the OFF position.

While ACC is set, you can increase the set speed by pushing the SET (+) button.

The driver's preferred units can be selected through the instrument panel settings if equipped. Refer to“Getting To Know Your Instrument Panel” for more information. The speed increment shown is dependent on the chosen speed unit of U.S. (mph) or Metric (km/h):

U.S. Speed (mph)

    Pushing the SET (+) button once will result in a 1 mph increase in set speed. Each subse- quent tap of the button results in an increase of 1 mph.
    If the button is continually pushed, the set speed will continue to increase in 5 mph increments until the button is released. The increase in set speed is reflected in the instrument cluster display.

Metric Speed (km/h)

    Pushing the SET (+) button once will result in a 1 km/h increase in set speed. Each subse- quent tap of the button results in an increase of 1 km/h.
    If the button is continually pushed, the set speed will continue to increase in 10 km/h increments until the button is released. The increase in set speed is reflected in the instrument cluster display.

While ACC is set, the set speed can be decreased by pushing the SET (-) button.

The driver's preferred units can be selected through the instrument panel settings if equipped. Refer to“Getting To Know Your Instrument Panel” for more information. The speed decrement shown is dependent on the chosen speed unit of U.S. (mph) or Metric (km/h):

U.S. Speed (mph)

    Pushing the SET (-) button once will result in a 1 mph decrease in set speed. Each subse- quent tap of the button results in a decrease of 1 mph.
    If the button is continually pushed, the set speed will continue to decrease in 5 mph decrements until the button is released. The decrease in set speed is reflected in the instrument cluster display.

Metric Speed (km/h)

    Pushing the SET (-) button once will result in a 1 km/h decrease in set speed. Each subse- quent tap of the button results in a decrease of 1 km/h.

    If the button is continually pushed, the set speed will continue to decrease in 10 km/h decrements until the button is released. The decrease in set speed is reflected in the instrument cluster display.
    When you override and push the SET (+) button or SET (-) buttons, the new set speed will be the current speed of the vehicle.
    When you use the SET (-) button to decel- erate, if the engine’s braking power does not slow the vehicle sufficiently to reach the set speed, the brake system will automatically slow the vehicle.
    The ACC system applies the brake down to a full stop when following a target vehicle. If an ACC host vehicle follows a target vehicle to a standstill, the host vehicle will release the vehicle brakes two seconds after coming to a full stop.
    The ACC system maintains set speed when driving uphill and downhill. However, a slight speed change on moderate hills is normal. In addition, downshifting may occur while climbing uphill or descending downhill. This is normal operation and necessary to main- tain set speed. When driving uphill and down- hill, the ACC system will cancel if the braking temperature exceeds normal range (over- heated).

SETTING THE FOLLOWING DISTANCE IN ACC

The specified following distance for ACC can be set by varying the distance setting between four bars (longest), three bars (long), two bars (medium) and one bar (short). Using this distance setting and the vehicle speed, ACC calculates and sets the distance to the vehicle ahead. This distance setting displays in the instrument cluster display.

Distance Settings

1 — Longest Distance Setting (Four Bars) 2 — Long Distance Setting (Three Bars) 3 — Medium Distance Setting (Two Bars) 4 — Short Distance Setting (One Bar)

To increase the distance setting, push the Distance Setting Increase button and release. Each time the button is pushed, the distance setting increases by one bar (longer).

To decrease the distance setting, push the Distance Setting Decrease button and release. Each time the button is pushed, the distance setting decreases by one bar (shorter).

If there is no vehicle ahead, the vehicle will maintain the set speed. If a slower moving vehicle is detected in the same lane, the instrument cluster displays the ACC Set With Target Light, and the system adjusts vehicle speed automatically to maintain the distance setting, regardless of the set speed.

The vehicle will then maintain the set distance 5

until:

    The vehicle ahead accelerates to a speed above the set speed.
    The vehicle ahead moves out of your lane or view of the sensor.
    The distance setting is changed.
    The system disengages (refer to the informa- tion on ACC Activation).

The maximum braking applied by ACC is limited; however, the driver can always apply the brakes manually, if necessary.

The brake lights will illuminate whenever the ACC system applies the brakes.

A Proximity Warning will alert the driver if ACC predicts that its maximum braking level is not sufficient to maintain the set distance. If this occurs, a visual alert“BRAKE” will flash in the instrument cluster display and a chime will sound while ACC continues to apply its maximum braking capacity.

Brake Alert

The“BRAKE!” Screen in the instrument cluster display is a warning for the driver to take action and does not necessarily mean that the Forward Collision Warning system is applying the brakes autonomously.

When driving with ACC engaged and following a vehicle, the system will provide an additional acceleration up to the ACC set speed to assist in passing the vehicle. This additional acceleration is triggered when the driver utilizes the left turn signal and will only be active when passing on the left hand side.

ACC OPERATION AT STOP

If the ACC system brings your vehicle to a standstill while following a target vehicle, if the target vehicle starts moving within two seconds of your vehicle coming to a standstill, your vehicle will resume motion without the need for any driver action.

If the target vehicle does not start moving within two seconds of your vehicle coming to a standstill, the ACC with Stop system will cancel and the brakes will release. A cancel message will display on the instrument cluster display and produce a warning chime. Driver intervention will be required at this moment.

While ACC with Stop is holding your vehicle at a standstill, if the driver seat belt is unbuckled or the driver door is opened, the ACC with Stop system will cancel and the brakes will release. A cancel message will display on the instrument cluster display and produce a warning chime. Driver intervention will be required at this moment.

ADAPTIVE CRUISE CONTROL (ACC) MENU

The instrument cluster display will show the current ACC system settings. The instrument cluster display is located in the center of the instrument cluster. The information it displays depends on ACC system status.

Push the Adaptive Cruise Control (ACC) on/off button (located on the steering wheel) until one of the following appears in the instrument cluster display:

When ACC is deactivated, the display will read“Adaptive Cruise Control Off.”

When ACC is activated, but the vehicle speed setting has not been selected, the display will read“Adaptive Cruise Control Ready.”

When the SET (+) or the SET (-) button (located on the steering wheel) is pushed, the display will read“ACC SET.”

When ACC is set, the set speed will show in the instrument cluster display.

The ACC screen may display once again if any ACC activity occurs, which may include any of the following:

    System Cancel
    Driver Override
    System Off
    ACC Proximity Warning
    ACC Unavailable Warning

The instrument cluster display will return to the last display selected after five seconds of no ACC display activity

“Wipe Front Radar Sensor In Front Of Vehicle” Warning

The“ACC/FCW Unavailable Wipe Front Radar Sensor” warning will display and also a chime will indicate when conditions temporarily limit system performance.

This most often occurs at times of poor visibility, such as in snow or heavy rain. The ACC system may also become temporarily blinded due to obstructions, such as mud, dirt or ice. In these cases, the instrument cluster display will display“ACC/FCW Unavailable Wipe Front Radar Sensor” and the system will deactivate.

The“ACC/FCW Unavailable Wipe Front Radar Sensor” message can sometimes be displayed while driving in highly reflective areas (i.e. tunnels with reflective tiles, or ice and snow).

The ACC system will recover after the vehicle 5

has left these areas. Under rare conditions,

when the radar is not tracking any vehicles or objects in its path this warning may temporarily occur.

If the“ACC/FCW Unavailable Wipe Front Radar Sensor” warning is active Normal (Fixed Speed) Cruise Control is still available. For additional information refer to“Normal (Fixed Speed) Cruise Control Mode” in this section.

If weather conditions are not a factor, the driver should examine the sensor. It may require cleaning or removal of an obstruction. The sensor is located in the center of the vehicle behind the lower grille.

To keep the ACC system operating properly, it is important to note the following maintenance items:

    Always keep the sensor clean. Carefully wipe the sensor lens with a soft cloth. Be cautious not to damage the sensor lens.
    Do not remove any screws from the sensor. Doing so could cause an ACC system malfunction or failure and require a sensor realignment.
    If the sensor or front end of the vehicle is damaged due to a collision, see an autho- rized dealer for service.
    Do not attach or install any accessories near the sensor, including transparent material or aftermarket grilles. Doing so could cause an ACC system failure or malfunction.

When the condition that deactivated the system is no longer present, the system will return to the“Adaptive Cruise Control Off” state and will resume function by simply reactivating it.

    If the“ACC/FCW Unavailable Wipe Front Radar Sensor” message occurs frequently (e.g. more than once on every trip) without any snow, rain, mud, or other obstruction, have the radar sensor realigned at an autho- rized dealer.
    Installing a snow plow, front-end protector, an aftermarket grille or modifying the grille is not recommended. Doing so may block the sensor and inhibit ACC/FCW operation.

“Clean Front Windshield” Warning

The“ACC/FCW Limited Functionality Clean Front Windshield” warning will display and also a chime will indicate when conditions temporarily limit system performance. This most often occurs at times of poor visibility, such as in snow or heavy rain and fog. The ACC system may also become temporarily blinded due to obstructions, such as mud, dirt, or ice on windshield and fog on the inside of glass. In these cases, the instrument cluster display will display“ACC/FCW Limited Functionality Clean Front Windshield” and the system will have degraded performance.

The“ACC/FCW Limited Functionality Clean Front Windshield” message can sometimes be displayed while driving in adverse weather conditions. The ACC/FCW system will recover after the vehicle has left these areas. Under rare conditions, when the camera is not tracking any vehicles or objects in its path this warning may temporarily occur.

If weather conditions are not a factor, the driver should examine the windshield and the camera located on the back side of the inside rearview mirror. They may require cleaning or removal of an obstruction.

When the condition that created limited functionality is no longer present, the system will return to full functionality.

If the“ACC/FCW Limited Functionality Clean Front Windshield” message occurs frequently (e.g. more than once on every trip) without any snow, rain, mud, or other obstruction, have the windshield and forward facing camera inspected at an authorized dealer.

If the system turns off, and the instrument cluster displays“ACC/FCW Unavailable Service Required” or“Cruise/FCW Unavailable Service Required”, there may be an internal system fault or a temporary malfunction that limits ACC functionality. Although the vehicle is still drivable under normal conditions, ACC will be temporarily unavailable. If this occurs, try activating ACC again later, following an ignition cycle. If the problem persists, see an authorized dealer.

PRECAUTIONS WHILE DRIVING WITH ACC

In certain driving situations, ACC may have detection issues. In these cases, ACC may brake late or unexpectedly. The driver needs to stay alert and may need to intervene.

Towing a trailer is not advised when using ACC.

ACC may not detect a vehicle in the same lane that is offset from your direct line of travel, or a vehicle merging in from a side lane. There may not be sufficient distance to the vehicle ahead. The offset vehicle may move in and out of the line of travel, which can cause your vehicle to brake or accelerate unexpectedly.

Offset Driving Condition Example

When driving on a curve with ACC engaged, the system may decrease the vehicle speed and acceleration for stability reasons, with no target vehicle detected. Once the vehicle is out of the curve the system will resume your original set speed. This is a part of normal ACC system functionality.

On tight turns ACC performance may be limited.

5

Turn Or Bend Example

When driving on hills, ACC may not detect a vehicle in your lane. Depending on the speed, vehicle load, traffic conditions, and the steepness of the hills, ACC performance may be limited.

ACC Hill Example

ACC may not detect a vehicle until it is completely in the lane in which you are traveling. In the illustration shown, ACC has not yet detected the vehicle changing lanes and it may not detect the vehicle until it's too late for the ACC system to take action. ACC may not detect a vehicle until it is completely in the lane. There may not be sufficient distance to the lane-changing vehicle. Always be attentive and ready to apply the brakes if necessary.

Lane Changing Example

Some narrow vehicles traveling near the outer edges of the lane or edging into the lane are not detected until they have moved fully into the lane. There may not be sufficient distance to the vehicle ahead.

Narrow Vehicle Example

ACC does not react to stationary objects and stationary vehicles. For example, ACC will not react in situations where the vehicle you are following exits your lane and the vehicle ahead is stopped in your lane. Always be attentive and ready to apply the brakes if necessary.

NORMAL (FIXED SPEED) CRUISE 5

In addition to Adaptive Cruise Control mode, a Normal (Fixed Speed) Cruise Control mode is available for cruising at fixed speeds. The Normal (Fixed Speed) Cruise Control mode is designed to maintain a set cruising speed without requiring the driver to operate the accelerator. Cruise Control can only be operated if the vehicle speed is above 20 mph (32 km/h).

To change between the different control modes, push the Adaptive Cruise Control (ACC) on/off button which turns the ACC and the Normal (Fixed Speed) Cruise Control off. Pushing the Normal (Fixed Speed) Cruise Control on/off button will result in turning on (changing to) the Normal (Fixed Speed) Cruise Control mode.

Turn the Normal (Fixed Speed) Cruise Control on. When the vehicle has reached the desired speed, push the SET (+) or SET (-) button and release.

Release the accelerator and the vehicle will operate at the selected speed. Once a speed has been set a message“CRUISE CONTROL SET

TO MPH (km/h)” will appear indicating what speed was set. This light will turn on when the system is turned on via the on/off control. It turns green when the cruise control is set.

When the Normal (Fixed Speed) Cruise Control is set, you can increase speed by pushing the SET (+) button.

The driver's preferred units can be selected through the instrument cluster display. Refer to“Getting To Know Your Instrument Panel” for more information. The speed increment shown is dependent on the speed of U.S. (mph) or Metric (km/h) units:

U.S. Speed (mph)

    Pushing the SET (+) button once will result in a 1 mph increase in set speed. Each subse- quent tap of the button results in an increase of 1 mph.
    If the button is continually pushed, the set speed will continue to increase in 5 mph increments until the button is released. The increase in set speed is reflected in the instrument cluster display.

Metric Speed (km/h)

    Pushing the SET (+) button once will result in a 1 km/h increase in set speed. Each subse- quent tap of the button results in an increase of 1 km/h.
    If the button is continually pushed, the set speed will continue to increase in 10 km/h increments until the button is released. The increase in set speed is reflected in the instrument cluster display.

When the Normal (Fixed Speed) Cruise Control is set, you can decrease speed by pushing the SET (-) button.

The driver's preferred units can be selected through the instrument cluster display. Refer to“Getting To Know Your Instrument Panel” for more information. The speed decrement shown is dependent on the speed of U.S. (mph) or Metric (km/h) units:

U.S. Speed (mph)

    Pushing the SET (-) button once will result in a 1 mph decrease in set speed. Each subse- quent tap of the button results in a decrease of 1 mph.
    If the button is continually pushed, the set speed will continue to decrease in 5 mph decrements until the button is released. The decrease in set speed is reflected in the instrument cluster display.

Metric Speed (km/h)

    Pushing the SET (-) button once will result in a 1 km/h decrease in set speed. Each subse- quent tap of the button results in a decrease of 1 km/h.
    If the button is continually pushed, the set speed will continue to decrease in 10 km/h decrements until the button is released. The decrease in set speed is reflected in the instrument cluster display.

The following conditions will cancel the Normal (Fixed Speed) Cruise Control without clearing the memory:

    The brake pedal is applied.
    The CANC button is pushed.
    The Electronic Stability Control/Traction Control System (ESC/TCS) activates.

    The vehicle parking brake is applied.
    The braking temperature exceeds normal range (overheated).
    The gear selector is removed from the DRIVE position.
    The driver switches ESC to Full Off mode.

To resume a previously set speed, push the RES button and release. Resume can be used at any speed above 20 mph (32 km/h).

The system will turn off and erase the set speed in memory if:

    The Normal (Fixed Speed) Cruise Control on/ off button is pushed.
    The ignition is placed in the OFF position.
    The Adaptive Cruise Control (ACC) on/off button is pushed.
