Adaptive Cruise Control (If Equipped)
How Does Adaptive Cruise Control With Stop and Go Work
Adaptive cruise control with stop and go uses radar and camera sensors to adjust the speed of your vehicle to maintain a set gap from the vehicle in front of you in the same lane while following it to a complete stop. You can also engage the system to follow a vehicle in front of you and adjust set speed while stopped.
What Is Adaptive Cruise Control With Lane Centering
Adaptive cruise control with lane centering uses radar and camera sensors to help keep your vehicle in the lane by applying continuous assistance steering torque input toward the lane center on highways.
Note: The adaptive cruise control gap setting operates normally.
What Is Intelligent Adaptive Cruise Control
Intelligent adaptive cruise control combines speed sign recognition with adaptive cruise control to adjust the cruise set speed to the speed limit detected by the speed sign recognition system. For example, if the speed sign recognition system detects a 50 mph (80 km/h) speed limit, the cruise set speed is updated to 50 mph (80 km/h) +/- the driver's selected speed offset.
Note: The adaptive cruise control gap setting operates normally.

Adaptive Cruise Control Precautions - Vehicles With: Stop and Go
| WARNING: You are responsible for controlling your vehicle at all times. The system is designed to be an aid and does not relieve you of your responsibility to drive with due care and attention. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death. WARNING: Pay close attention to changing road conditions such as entering or leaving a highway, on roads with intersections or roundabouts, roads without visible lanes of travel, roads that are winding, slippery, unpaved, or steep slopes. WARNING: The system does not control speed in low traction conditions or extremely steep slopes. The system is designed to be an aid and does not relieve you of your responsibility to drive with due care and attention. Failure to follow this instruction could result in personal injury. WARNING: The system is not a crash warning or avoidance system. WARNING: Do not use the system when towing a trailer that has aftermarket electronic trailer brake controls. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death. WARNING: Do not use tire sizes other than those recommended because this can affect the normal operation of the system. Failure to do so may result in a loss of vehicle control, which could result in serious injury. WARNING: Do not use the system with a snow plow blade installed. WARNING: Do not use the system in poor visibility, for example fog, heavy rain, spray or snow. |
When Following a Vehicle
| WARNING: When following a vehicle that is braking, your vehicle does not always decelerate quickly enough to avoid a crash without driver intervention. Apply the brakes when necessary. Failure to follow this instruction could result in personal injury or death. |
Hilly Condition Usage
You should select a lower gear when the system is active in situations such as prolonged downhill driving on steep grades, for example in mountainous areas. The system needs additional engine braking in these situations to reduce the load on the vehicle’s regular brake system to prevent it from overheating.
Note: An audible alarm sounds and the system shuts down if it applies brakes for an extended period of time. This allows the brakes to cool. The system functions normally again after the brakes cool.
Adaptive Cruise Control Limitations - Vehicles With: Lane Centering
Adaptive cruise control limitations apply to lane centering unless stated otherwise or contradicted by a lane centering limitation. See Adaptive Cruise Control Limitations - Vehicles With: Stop and Go.
The system may not correctly operate in any of the following conditions:
- The lane is too narrow or wide.
- The system does not detect at least one lane marking or when lanes merge or split.
- Limited steering torque input is applied.
- Areas under construction or new infrastructure.
- When modifications to the steering system have been made.
- When using a spare tire.
Note: The driving assistance torque is limited and may not be sufficient for all driving situations such as driving through tight curves or driving through curves at high speeds.
Note: In exceptional conditions, the system may deviate from the center line.

Sensor Limitations
| WARNING: On rare occasions, detection issues can occur due to the road infrastructures, for example bridges, tunnels and safety barriers. In these cases, the system may brake late or unexpectedly. At all times, you are responsible for controlling your vehicle, supervising the system and intervening, if required. WARNING: If the system malfunctions, have your vehicle checked as soon as possible. WARNING: Large contrasts in outside lighting can limit sensor performance. WARNING: The system only warns of vehicles detected by the radar sensor. In some cases there may be no warning or a delayed warning. Apply the brakes when necessary. Failure to follow this instruction could result in personal injury or death. WARNING: The system may not detect stationary or slow moving vehicles below 6 mph (10 km/h). WARNING: The system does not detect pedestrians or objects in the road. WARNING: The system does not detect oncoming vehicles in the same lane. WARNING: The system may not operate properly if the sensor is blocked. Keep the windshield free from obstruction. WARNING: The system may incorrectly track lane markings as other structures or objects. This can result in a false or missed warning. |
The camera is mounted on the windshield behind the interior mirror.
The radar sensor is in the lower grille.
Note: You cannot see the sensor. It is behind a fascia panel.
Note: Keep the front of your vehicle free of dirt, metal badges or objects. Vehicle front protectors, aftermarket lights, additional paint or plastic coatings could also degrade sensor performance.
A message displays if something obstructs the camera or the sensor. When something blocks the sensor, the system cannot detect a vehicle ahead and does not function. See Adaptive Cruise Control – Information Messages - Vehicles With: Lane Centering.
The radar sensor has a limited field of view. It may not detect vehicles at all or detect a vehicle later than expected in some situations. The lead vehicle image does not illuminate if the system does not detect a vehicle in front of you.
Detection issues can occur:
A When driving on a different line than the vehicle in front.B With vehicles that edge into your lane. The system can only detect these vehicles once they move fully into your lane.C There may be issues with the detection of vehicles in front when driving into and coming out of a bend or curve in the road. |
In these cases, the system may brake late or unexpectedly.
If something hits the front end of your vehicle or damage occurs, the radar-sensing zone may change. This could cause missed or false vehicle detection.
Optimal system performance requires a clear view of the road by the windshield-mounted camera.
Optimal performance may not occur if:
- The camera is blocked.
- There is poor visibility or lighting conditions.
- There are bad weather conditions.
Switching Adaptive Cruise Control On and Off
The cruise controls are on the steering wheel.
Switching Adaptive Cruise Control On
The indicator, current gap setting and set speed appear in the information display.
Switching Adaptive Cruise Control Off
Note: You erase the set speed when you switch the system off.
Automatic Cancellation or Deactivation
The system may cancel if:
- The tires lose traction.
- You apply the parking brake.
The system may cancel and set the parking brake if:
- You unbuckle the seatbelt and open the driver door after you stop your vehicle.
- Your vehicle is at a stop continuously for more than three minutes.
The system may turn off or prevent activating when requested if:
- The vehicle has a blocked sensor.
- The brake temperature is too high.
- There is a failure in the system or a related system.
Setting the Adaptive Cruise Control Speed
Drive to the speed you prefer.
Take your foot off the accelerator pedal.
The indicator, current gap setting and set speed appear in the information display.
A vehicle image illuminates if there is a vehicle detected in front of you.
Note: When adaptive cruise control is active, the speedometer may vary slightly from the set speed displayed in the information display.
Setting the Adaptive Cruise Speed from a Complete Stop
The set speed adjusts to 20 mph (30 km/h).
The indicator, current gap setting and set speed appear in the information display.
Note: The system activates from a complete stop only when it detects a lead vehicle in close proximity.
Manually Changing the Set Speed
Press and hold the toggle button upward to increase the set speed in large increments. Release the button when the set speed is equal to your desired speed.
Press and hold the toggle button downward to decrease the set speed in large increments. Release the button when the set speed is equal to your desired speed.
You can also press the accelerator or brake pedal until you reach the speed you prefer. Press the toggle button upward or downward to select the current speed as the set speed.
The system may apply the brakes to slow the vehicle to the new set speed. The set speed continuously displays in the information display when the system is active.
Setting the Adaptive Cruise Control Gap
The selected gap appears in the instrument cluster display as shown by the bars in the image.
Note: The gap setting is time dependent and therefore, the distance adjusts with your vehicle speed.
Note: It is your responsibility to select a gap appropriate to the driving conditions.
Adaptive Cruise Control Gap Settings
| Graphic Display, Bars Indicated Between Vehicles | Gap Distance | Dynamic Behavior |
|---|---|---|
| 1 | Closest. | Sport. |
| 2 | Close. | Normal. |
| 3 | Medium. | Normal. |
| 4 | Far. | Comfort. |
Each time you switch the system on, it selects the last chosen gap setting.
Following a Vehicle
When a vehicle ahead of you enters the same lane or a slower vehicle is ahead in the same lane, the vehicle speed adjusts to maintain the gap setting.
Note: When you are following a vehicle and you switch on a turn signal lamp, adaptive cruise control may provide a small, temporary acceleration to help you pass.
Your vehicle maintains a consistent gap from the vehicle ahead until:
- The vehicle in front of you accelerates to a speed above the set speed.
- The vehicle in front of you moves out of the lane you are in.
- You set a new gap distance.
The system applies the brakes to slow down your vehicle to maintain a safe gap distance from the vehicle in front of you. The system only applies limited braking. You can override the system by applying the brakes.
Note: The brakes may emit noise when applied by the system.
If the system determines that its maximum braking level is not sufficient, an audible warning sounds, a message appears in the instrument cluster display and an indicator flashes when the system continues to brake. Take immediate action.
Canceling the Set Speed
The set speed does not erase.
Resuming the Set Speed
Your vehicle speed returns to the previously set speed and gap setting. The set speed displays continuously in the instrument cluster display when the system is active.
Note: Only use resume if you are aware of the set speed and intend to return to it.
Resuming the Set Speed from a Complete Stop
If your vehicle follows a vehicle to a complete stop and remains stationary for less than three seconds, your vehicle accelerates from a stationary position to follow the vehicle ahead.

Note: If it does not detect valid lane markings, the system stays inactive until valid markings are available.
You can override the system at any time by steering your vehicle.
System Alerts and Automatic Cancellation
You must keep your hands on the steering wheel at all times.
When the system is active and detects no steering activity for a certain period of time, the system alerts you to put your hands on the steering wheel. If you do not react to the warnings the system cancels and slows your vehicle down to idle speeds while maintaining steering control.
The system also alerts you if your vehicle crosses lane markings without detected steering activity.
Note: The system may detect a light grip or touch on the steering wheel as hands-off driving.
When an external condition cancels the system, for example, no lane markings available, a tone sounds and a message appears in the information display.
Automatic cancellation can also occur if:
- The lane becomes too wide or too narrow.
- The system cannot detect valid lane markings.
- Lane markings are crossed.
Note: The system disables until the next key cycle if your vehicle slows down due to driver inactivity twice within a key cycle.
