WARNING:
Always pay close attention to changing road conditions, especially when using adaptive cruise control. Adaptive cruise control cannot replace attentive driving. Failing to follow any of the warnings below or failing to pay attention to the road may result in a crash, serious injury or death.
WARNING:
Adaptive cruise control is not a crash warning or avoidance system.
WARNING:
Adaptive cruise control does not detect stationary or slow moving vehicles below 6 mph (10 km/h).
WARNING:
Adaptive cruise control does not detect pedestrians or objects in the roadway.
WARNING:
Adaptive cruise control does not detect oncoming vehicles in the same lane.
WARNING:
Do not use the adaptive cruise control when entering or leaving a highway, in heavy traffic or on roads that are winding, slippery or unpaved.
WARNING:
Do not use in poor visibility, specifically fog, rain, spray or snow.
WARNING:
Do not use adaptive cruise control while you have a snow plow blade installed.
WARNING:
Do not use the system when towing a trailer with aftermarked 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.
WARNING:
Do not use tire sizes other than those recommended because this can affect the normal operation of the system. Failing to do so may result in a loss of vehicle control, which could result in serious injury. |
Note:
It is your responsibility to stay alert, drive safely and control the vehicle at all times.
The system adjusts your speed to maintain a proper distance between you and the vehicle in front of you in the same lane. You can select from one of four gap settings.
The controls for using your cruise control are located on the steering wheel.
Switching the System On
Press and release ON.
The information display shows the grey indicator light.
The current gap setting and SET also shows.
Setting a Speed
- Accelerate to the desired speed.
- Press and release SET+. The memory stores the vehicle speed.
- The information display shows a green indicator light, current gap setting and the desired set speed.
- Take your foot off the accelerator pedal.
- A lead vehicle graphic illuminates if the system detects a vehicle 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.
Following a Vehicle
WARNING:
When following a vehicle in front of you, 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.
WARNING:
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. Failing to do so may result in a crash, serious injury or death. |
Note:
The brakes may emit a sound when the adaptive cruise control system is active.
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. The distance setting is adjustable.
The lead vehicle graphic illuminates.
The vehicle maintains a constant distance 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 your lane or out of view.
- The vehicle speed falls below
12.4 mph (20 km/h).
- You set a new gap distance.
The system applies the brakes to slow the vehicle to maintain a safe distance from the vehicle in front. The system applies only limited maximum braking. Press the brake pedal to override the system.
If the system predicts that its maximum braking level is insufficient, an audible warning sounds while the system continues to brake. A red warning bar appears on the windshield heads-up display. Take immediate action to slow or stop the vehicle.
The system may provide slight temporary acceleration when you use your driver side directional indicator while following a lead vehicle, to aid in passing the vehicle.
Setting the Gap Distance
Note:
It is your responsibility to select a gap appropriate to the driving conditions.
AGap decrease. BGap increase.
|
Press the gap control to decrease or increase the distance between your vehicle and the vehicle in front of you.
Bars in the graphic show the selected gap distance. You can select between four gap settings.
Note:
When you select Tow/Haul Mode, the gap distance is increased slightly.

Each time you start the vehicle, the system selects the last chosen gap for the current driver.
Disengaging the System
Press the brake pedal or press CNCL. The last set speed displays in grey but does not erase.
Overriding the System
WARNING:
Whenever you press the accelerator pedal and override the system, the system no longer automatically applies the brakes to maintain separation from any vehicle ahead. |
While 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 lead vehicle graphic does not show in the information display. The system resumes operation when you release the accelerator pedal. The vehicle speed decreases to the set speed, or to a lower speed if following a slower vehicle. | |
Changing the Set Speed
- Accelerate or brake to the desired speed, then press and release SET+.
- Press and hold SET+ or SET- until the desired set speed shows on the information display. The vehicle speed gradually changes to the selected speed.
- Press and release SET+ or SET-. The set speed changes in approximately
1.2 mph (2 km/h).
The system may apply the brakes to slow the vehicle to the new set speed. The set speed displays continuously in the information display while the system is active.
Resuming the Set Speed
Note:
Only use resume if you are aware of the set speed and intend to return to it.
Press and release RES. The vehicle returns to the previously set speed. The set speed shows continuously in the information display while the system is active.
Low Speed Automatic Cancellation
The system does not function at vehicle speeds below
12.4 mph (20 km/h). An audible alarm sounds and the automatic braking releases if the vehicle drops below this speed.
Hilly Condition Usage
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 when the brakes have cooled.
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.
Switching the System Off
Note:
The set speed memory erases when you switch off the system.
Press and release OFF or switch off the ignition.
Detection Issues
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. |
The radar sensor has a limited field of vision. 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.
In these cases the system may brake late or unexpectedly. 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 detections. Contact an authorized dealer to have them check for proper coverage and operation.
System Not Available
Conditions that can cause the system to deactivate or prevent the system from activating when requested include:
- A blocked sensor.
- High brake temperature.
- A failure in the system or a related system.
Note:
If you disable electronic stability control, adaptive cruise control is not available. See
Using Stability Control.
Blocked Sensor
A message displays if something obstructs the radar signals from the sensor. The sensor is behind a cover near the driver side of the lower grille. The system cannot detect a vehicle ahead and does not function when something obstructs the radar signals. The following table lists possible causes and actions for this message displaying.
Cause
| Action
|
---|
The surface of the radar in the grille is dirty or obstructed in some way.
| Clean the grille surface in front of the radar or remove the object causing the obstruction.
|
The surface of the radar in the grille is clean but the message remains in the display.
| Wait a short time. It may take several minutes for the radar to detect that it is free from obstruction.
|
Heavy rain or snow is interfering with the radar signals.
| Do not use the system in these conditions because it may not detect any vehicles ahead.
|
Swirling water, or snow or ice on the surface of the road may interfere with the radar signals.
| Do not use the system in these conditions because it may not detect any vehicles ahead.
|
You are in a desert or remote area with no other vehicles and no roadside objects.
| Wait a short time or switch to normal cruise control.
|
Due to the nature of radar technology, it is possible to get a blockage warning and not have a blockage. This can happen, for example, when driving in sparse rural or desert environments. A false blocked condition either self clears or clears after a key cycle.
Switching to Normal Cruise Control
WARNING:
Normal cruise control does not brake due to slower vehicles. Always be aware of which mode you have selected and apply the brakes when necessary. |
You can manually change from adaptive cruise control to normal cruise control through the information display. See
General Information.
The cruise control indicator light replaces the adaptive cruise control indicator light if you select normal cruise control. The gap setting does not display, the system does not automatically respond to lead vehicles and automatic braking is not active. The system recalls its last setting when you start your vehicle. | |
