2018 Ford F-350 Owners Manual - Cruise Control

Cruise Control

Cruise control lets you maintain a set speed without keeping your foot on the accelerator pedal. You can use cruise control when your vehicle speed is greater than 20 mph (30 km/h).

Do not use cruise control on winding roads, in heavy traffic or when the road surface is slippery. This could

result in loss of vehicle control, serious injury or death.

When you are going downhill, your vehicle speed could increase above the set speed. The system does not

apply the brakes.

Note: Cruise control disengages if the vehicle speed decreases more than 10 mph (16 km/h) below the set speed when driving uphill.

The cruise controls are on the steering wheel.

Press ON.

The indicator appears in the information display.

Drive to desired speed.

Press SET+ or SET-.

Take your foot off the accelerator pedal.

Note: The indicator changes color.

Note: If you accelerate by pressing the accelerator pedal, the set speed will not change. When you release the accelerator pedal, your vehicle returns to the speed that you previously set.

Press SET+ or SET- to change the set speed in small increments.

Press the accelerator or brake pedal until you reach the desired speed. Press SET+ or SET-.

Press and hold SET+ or SET-. Release the control when you reach the desired speed.

Press CNCL or tap the brake pedal. The set speed does not erase.

Press RES.

Note: You erase the set speed when you switch the system off.

Press OFF when the system is in standby mode, or switch the ignition off.

CONTROL (If Equipped)

Always pay close attention to changing road conditions when using adaptive cruise control. The system

does not replace attentive driving. Failing to pay attention to the road may result in a crash, serious injury or death.

Do not use the adaptive cruise control when entering or leaving a highway, on roads with intersections

or roundabouts or non-vehicular traffic or roads that are winding, slippery, unpaved, or steep slopes.

Do not use the system in poor visibility, for example fog, heavy rain, spray or snow.

Do not use the system when towing a trailer with aftermarket trailer brake controls. Aftermarket trailer

brakes will not function properly when you switch the system on because the brakes are electronically controlled. Failing to do so may result in loss of vehicle control, which could result in serious injury.

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.

Adaptive cruise control may not detect stationary or slow moving vehicles below 6 mph (10 km/h).

Adaptive cruise control does not detect pedestrians or objects in the road.

Adaptive cruise control does not detect oncoming vehicles in the same lane.

Adaptive cruise control is not a crash warning or avoidance system.

Do not use adaptive cruise control with a snow plow blade installed.

Note: It is your responsibility to stay alert, drive safely and be in control of the vehicle at all times.

The system adjusts your vehicle speed to maintain the set gap between you and the vehicle in front of you in the same lane.

You can select four gap settings.

The system uses a radar sensor that projects a beam directly in front of your vehicle.

E183737

The adaptive cruise controls are on the steering wheel.

Press ON.

The indicator, current gap setting and set speed appear in the information display.

244

E233874

Note: When adaptive cruise control is active, the speedometer may vary slightly from the set speed displayed in the information display.

Drive to desired speed.

Press SET+ or SET-.

A green indicator light, the current gap setting and your set speed appear in the information display.

Take your foot off the accelerator pedal.

E233874

A vehicle image illuminates if the system detects a vehicle in front of you.

When following a vehicle, your vehicle does not decelerate automatically to a stop, nor does

your vehicle always decelerate quickly enough to avoid a crash without driver intervention. Always apply the brakes when necessary. Failing to do so may result in a crash, serious injury or death.

Adaptive cruise control only warns of vehicles detected by the radar sensor. In some cases there may be

no warning or a delayed warning. You should always apply the brakes when necessary. Failure to do so may result in a crash, serious injury or death.

Note: When you are following a vehicle and you switch on a direction indicator, adaptive cruise control may provide a small temporary acceleration to help you pass.

Note: The brakes may emit noise when applied by the system.

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 a preset gap distance. A vehicle graphic illuminates in the instrument cluster. A vehicle graphic illuminates in the instrument cluster.

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 your vehicle to maintain a safe gap distance from the vehicle in front. The system only applies limited braking. You can override the system by applying the brakes.

245

If the system determines that its maximum braking level will not be sufficient, an audible warning sounds when the system continues to brake. A red warning bar displays on the windshield and you must take immediate action.

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.

You can decrease or increase the distance between your vehicle and the vehicle in front by pressing the gap control.

The selected gap appears in the information display as shown by the bars in the image.

Each time you switch the system on, it selects the last chosen gap setting.

E183739

E233874

Gap decrease. Gap increase.

If you override the system by pressing the accelerator pedal, it does not automatically apply the brakes to

maintain a gap from any vehicle ahead.

When you press the accelerator pedal, you override the set speed and gap distance.

When you override the system, the green indicator light illuminates and the vehicle

image does not appear in the information display.

The system resumes operation when you release the accelerator pedal. The vehicle speed decreases to the set speed, or a lower speed if following a slower vehicle.

246

Press SET+ or SET- to change the set speed in small increments.

Press the accelerator or brake pedal until you reach the desired speed. Press SET+ or SET-.

Press and hold SET+ or SET- to change the set speed in large increments. Release the control when you reach the desired speed.

The system may apply the brakes to slow the vehicle to the new set speed. The set speed displays continuously in the information display when the system is active.

Press CNCL or tap the brake pedal. The set speed does not erase.

Note: Only use resume if you are aware of the set speed and intend to return to it.

Press RES. Your vehicle speed returns to the previously set speed and gap setting. The set speed displays continuously in the information display when the system is active.

Note: If the engine speed drops too low, an audible warning sounds and a message appears in the information display.

Note: When towing with adaptive cruise control, switch on Tow/Haul Mode and Diesel Engine Brake.

Note: Tow/Haul mode increases the time gaps and allows more distance for braking.

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: You erase the set speed and gap setting when you switch the system off.

Press OFF when the system is in standby mode, or switch the ignition off.

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.

If the system malfunctions, have your vehicle checked as soon as possible.

Automatic braking releases.

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.

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 graphic does not illuminate if the system does not detect a vehicle in front of you.

247

E71621

Detection issues can occur:

When driving on a different line than the vehicle in front.

With vehicles that edge into your lane. The system can only detect these vehicles once they move fully into your lane.

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. You should stay alert and take action when necessary.

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.

Note: If you disable electronic stability control, adaptive cruise control is not available.

The system may not turn on if there is:

A blocked sensor.

High brake temperature.

A failure in the system or a related system.

E183741

Note: You cannot see the sensor. It is behind a fascia panel.

A message displays if something obstructs the radar signals from the sensor. The sensor is in the lower grille. The system cannot detect a vehicle ahead and does not function when something blocks the sensor.

248

Due to the nature of radar technology, it is possible to get a blockage warning with no actual block. This happens, for example, when driving in sparse rural or desert environments. A false blocked condition either self clears, or clears after you restart your vehicle.

Normal cruise control will not brake when your vehicle is approaching slower vehicles. Always be aware of

which mode you have selected and apply the brakes when necessary.

You can change from adaptive cruise control to normal cruise control through the information display.

The cruise control indicator light replaces the adaptive cruise control indicator light if you

select normal cruise control. The gap setting does not display, and the system does not respond to lead vehicles.

Automatic braking remains active to maintain set speed.
