WARNING
  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.
  Adaptive cruise control does not detect stationary or slow moving vehicles below 10  km/h.
  Do not use adaptive 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.
  Do not use adaptive cruise control when towing a trailer that has trailer brakes. The auto-brake component of the adaptive cruise control system does not operate the trailer brakes. Using adaptive cruise control when towing a trailer that has trailer brakes may result in the loss of vehicle control, which could result in serious injury.
  Adaptive cruise control is not a crash warning or avoidance system.
  Adaptive cruise control does not detect pedestrians or objects in the road.
  Adaptive cruise control does not detect oncoming vehicles in the same lane.
  Do not use the system in poor visibility, for example fog, heavy rain, spray or snow.
  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 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.

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 adaptive cruise controls are on the steering wheel.
Switching Adaptive Cruise Control On
Note:  Using cruise control with ECO Cruise switched on may change the operation of the system. This feature saves vehicle energy by relaxing acceleration compared to standard cruise control. For example, your vehicle may temporarily lose speed when going uphill.
Energi vehicles: ECO Cruise can be turned on or off through the information display. See Information Displays
Hybrid vehicles: ECO Cruise is included in EcoSelect which is turned on or off using the ECO button on the center console.
For additional information, refer to ECO Cruise and EcoSelect. See  Hybrid Electric Vehicle
Press and release ON.
  The indicator appears in the information display.

The current gap setting and set speed also appear in the information display.
Setting the Adaptive Cruise Speed
  1. Drive to desired speed.
  1. Press and release SET+. A green indicator light, the current gap setting and your set speed appear in the information display.
  1. Take your foot off the accelerator pedal.
Missing Image
  1. 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 appearing in the information display.
Following a Vehicle
WARNING
  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 the adaptive cruise control adjusts the brakes, you may hear a noise.
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. The lead vehicle graphic illuminates.
When you are following a vehicle and you switch on your left-turn signal, 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.
  • The vehicle speed falls below 20  km/h.
  • You set a new gap distance.
The vehicle applies brakes to slow the vehicle to maintain a safe distance from the vehicle in front. The maximum braking which the system can apply is limited. You can override the system by applying the brakes.
If the system predicts that its maximum braking level is insufficient, an audible warning sounds while the system continues to brake. The red warning bar appears on the windshield. You should 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.
Note:  It is your responsibility to select a gap appropriate to the driving conditions.
Missing Image
A Gap decrease.
B Gap increase.
Missing Image
The selected gap appears in the information display as shown by the bars in the graphic. Four gap distance settings are available.
Adaptive cruise control, distance between vehicle settings

Set speed  Graphic display, bars indicated between vehicles  Time gap, seconds  Distance gap  Dynamic behavior 
 km/h   m  
100  km/h 28  m Sport 
100  km/h 1.4  39  m Normal 
100  km/h 1.8  50  m Normal 
100  km/h 2.2  61  m Comfort 

Each time you start the vehicle, the system selects the last chosen gap setting.
Overriding the System
WARNING
  Whenever the driver is overriding the system by pressing the accelerator pedal, the system will not automatically apply the brakes to maintain separation from any vehicle ahead.

You can override the set speed and gap distance by pressing the accelerator pedal.
  When you override the system, the indicator light changes color and a vehicle graphic does not show in the information display.
The system will resume operation when you release the accelerator pedal. The vehicle speed will decrease to the set speed, or a lower speed if following a slower vehicle.
Changing the Set Speed
  • When you select km/h as the display measurement in the information display the set speed changes in approximately 2 km/h increments. When you select mph as the display measurement in the information display the set speed changes in approximately 1 mph increments.
  • Press the accelerator or brake pedal until you reach the desired speed. Press and release SET+.
  • Press and hold SET+ or SET-. 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.
Resuming the Set Speed
Press and release RES. The vehicle returns to the previously set speed. The set speed displays continuously in the information display while 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 does not operate below 20  km/h. An audible warning sounds and the automatic braking releases if the vehicle drops below this speed.
Automatic cancellation can also occur if:
  • The tires lose traction.
  • The engine speed is too low.
  • You apply the parking brake.
Note:  If the engine speed drops too low, the information display indicates low engine speed. Shift to a lower gear (manual transmission only) to avoid automatic cancellation.
Hilly Condition Usage
Note:  An audible alarm sounds and the system shuts down when it applies brakes for an extended period of time. This allows the brakes to cool. The system functions normally after the brakes have cooled.
You should select a lower gear position 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 them from overheating.
Switching Adaptive Cruise Control 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 may detect a vehicle later than expected in some situations. The lead vehicle graphic will not illuminate if the system does not detect a vehicle in front of you.
Missing Image
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. You should stay alert and intervene if 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 check the radar for proper coverage and operation.
System Not Available
Conditions that can cause the system to turn off or prevent the system from turning on when requested include:
  • A blocked sensor.
  • High brake temperature.
  • A failure in the system or a related system.
Blocked Sensor
Missing Image
A message appears if something obstructs the sensor's radar signals. The sensor is located 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 signal.
Note:  You cannot see the sensor, it is behind a fascia panel.
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 obstructing it. 
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 be blocked. This can happen, for example, when driving in sparse rural or desert environments. A false blocked condition will either self clear or clear after a key cycle.
Switching to Normal Cruise Control
WARNING
  Normal cruise control will 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 Information Displays
  The cruise control indicator light replaces the adaptive cruise control indicator light if you select normal cruise control. The gap setting will not display, the system will not automatically respond to lead vehicles and automatic braking will not activate.
