WARNING   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   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 unpaved, or steep slopes. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.
WARNING   WARNING:  Do not use the system in poor visibility, for example fog, heavy rain, spray or snow.
WARNING   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   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   WARNING:  The system may not detect stationary or slow moving vehicles below 6 mph (10 km/h).
WARNING   WARNING:  The system does not detect pedestrians or objects in the road.
WARNING   WARNING:  The system does not detect oncoming vehicles in the same lane.
WARNING   WARNING:  The system is not a crash warning or avoidance system.
WARNING   WARNING:  Do not use the system with a snow plow blade installed.

 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 directly projects a beam in front of your vehicle.

Take your foot off the accelerator pedal.
The indicator, current gap setting and set speed appear in the information display.
Adaptive Cruise Control Gap Lines
A vehicle graphic 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.
Following a Vehicle
WARNING   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.
WARNING   WARNING:  The system only warns of vehicles detected by the radar and camera sensors. 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.

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.
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.
  • Your vehicle speed falls below 12 mph (20 km/h).
  • 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.
If the system determines that its maximum braking level is not sufficient, an audible warning sounds, a message appears in the information display and an indicator flashes when the system continues to brake. Take immediate action.
Setting the Gap Distance
You can decrease or increase the distance between your vehicle and the vehicle in front by pressing the gap control.
Gap Control Decrease Icon  Press and release to decrease the gap distance.Adaptive Cruise Control Gap Increase  Press and release to increase the gap distance.
Adaptive Cruise Control Gap Lines
The selected gap appears in the information 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   Distance Gap   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.
Overriding the Set Speed
WARNING   WARNING:  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.
Adaptive Cruise Control Warning Light  Use the accelerator pedal normally to intentionally exceed the set speed limit.
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.
Changing the Set Speed
Cruise Control SET+ Button  Press and release to increase the set speed in small increments.Cruise control SET Button  Press and release to decrease the set speed in small increments.
Press and hold either button to change the set speed in large increments. Release the button when the set speed equals the speed you prefer.
Press the accelerator or brake pedal until you reach the speed you prefer. Press either button.
 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.
Canceling the Set Speed
Cruise Control CAN Button  Press and release the button or tap the brake pedal.
The set speed does not erase.
Resuming the Set Speed
Cruise Control Reset Button  Press and release the button.
 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:   Only use resume if you are aware of the set speed and intend to return to it.
Automatic Cancellation
The system is not functional at vehicle speeds below 12 mph (20 km/h). The information display indicates low engine speed, an audible alarm sounds and the automatic braking releases if the vehicle drops below this speed.
Automatic cancellation can also occur when:
  • The tires lose traction.
  • You apply the parking brake.
Note:   If the engine speed drops too low, an audible warning sounds and a message appears in the information display. Automatic braking releases.
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 normally functions again when the brakes have cooled.
Select a lower gear during prolonged downhill driving on steep slopes, such as mountainous areas, when the system is active. In such situations, the system needs additional engine braking to reduce the load on the vehicle’s regular brake system to prevent the brakes from overheating.
Switching Adaptive Cruise Control Off
ON/OFF  Press and release the button when the system is in standby mode, or switch the ignition off.
Note:   You erase the set speed and gap setting when you switch the system off.
Detection Issues
WARNING   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   WARNING:  If the system malfunctions, have your vehicle checked as soon as possible.

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.
Adaptive Cruise Control - Detection Issues
Detection issues can occur:
AWhen driving on a different line than the vehicle in front.
BWith vehicles that edge into your lane. The system can only detect these vehicles once they move fully into your lane.
CThere 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.
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.
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.
Blocked Sensor
Pre-Collision Assist Sensors
 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.
Note:   You cannot see the sensor. It is behind a fascia panel.
Keep the front of your vehicle free of dirt, metal badges or objects. Vehicle front protectors and aftermarket lights may also block the sensor.
Possible Causes and Actions for This Message Displaying:

Cause   Action  
The surface of the radar is dirty or obstructed.   Clean the grille surface in front of the radar or remove the object causing the obstruction.  
The surface of the radar 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.  
Water, 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 with no actual block. A false blocked condition either self clears, or clears after you restart your vehicle.
Switching to Normal Cruise Control
WARNING   WARNING:  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.

Cruise Control   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.
You can change from adaptive cruise control to normal cruise control through the information display.   See   General Information. 
Note:   The system remembers the last setting when you start your vehicle.
