WARNING: Adaptive cruise controlonly warns of vehicles detected by theradar sensor. In some cases there may beno warning or a delayed warning. Youshould always apply the brakes whennecessary. Failure to do so may result in acrash, serious injury or death.
When a vehicle ahead of you enters thesame lane or a slower vehicle is ahead in thesame lane, the vehicle speed adjusts tomaintain a preset gap distance. A vehiclegraphic appears in the information display.
Note:When you are following a vehicle andyou switch on a direction indicator, adaptivecruise control may provide a small temporaryacceleration to help you pass.
Note:The brakes may emit noise whenapplied by the system.
Your vehicle maintains a consistent gap fromthe vehicle ahead until:
•The vehicle in front of you accelerates toa speed above the set speed.
•The vehicle in front of you moves out ofthe 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 yourvehicle to maintain a safe gap distance fromthe vehicle in front. The system only applieslimited braking. You can override the systemby applying the brakes.
If the system determines that its maximumbraking level is not sufficient, an audiblewarning sounds when the system continuesto brake. A red warning bar displays on thewindshield and you must take immediateaction.
Setting the Gap Distance
You can decrease or increase the distancebetween your vehicle and the vehicle in frontby pressing the gap control.
Press the toggle button upward ordownward to set gap distance.
The selected gap appears in the informationdisplay as shown by the bars in the image.
Note:The gap setting is time dependent andtherefore the distance adjusts with yourvehicle speed.
Note:It is your responsibility to select a gapappropriate to the driving conditions.

Overriding the Set Speed
WARNING: If you override thesystem by pressing the accelerator pedal,it does not automatically apply the brakesto maintain a gap from any vehicle ahead.
When you press the accelerator pedal, youoverride the set speed and gap distance.
When you override the system, thegreen indicator light illuminatesand the vehicle image does notappear in the information display.
The system resumes operation when yourelease the accelerator pedal. The vehiclespeed decreases to the set speed, or a lowerspeed if following a slower vehicle.
Changing the Set Speed
Press the toggle button upward ordownward to increase or decreasethe set speed in small increments.
Press and hold either direction to changethe set speed in large increments. Releasethe button when you reach your preferredspeed.
Press the accelerator or brake pedal untilyou reach your preferred speed. Press thetoggle button either direction.
The system may apply the brakes to slowthe vehicle to the new set speed. The setspeed displays continuously in theinformation display when the system isactive.
Canceling the Set Speed
Press and release the button, ortap the brake pedal to cancel theset speed.
Note:The set speed is stored.
Resuming the Set Speed
Press and release to resume theset speed.
Note:Only use resume if you are aware ofthe set speed and intend to return to it.
Automatic Cancellation
The system is not functional at vehiclespeeds below 12 mph (20 km/h). Theinformation display indicates low enginespeed, an audible alarm sounds and theautomatic braking releases if the vehicledrops below this speed.

Automatic cancellation can also occur when:
•The tires lose traction.
•The engine speed is too low.
•You apply the parking brake.
Hilly Condition Usage
Select a lower gear when the system isactive in situations such as prolongeddownhill driving on steep grades, forexample in mountainous areas. The systemneeds additional engine braking in thesesituations to reduce the load on the vehicle’sregular brake system to prevent it fromoverheating.
Note:An audible alarm sounds and thesystem shuts down if it applies brakes for anextended period of time. This allows thebrakes to cool. The system functionsnormally again after the brakes cool.
Switching Adaptive Cruise Control Off
Press and release the button whenthe system is in standby mode, orswitch the ignition off.
Note:You erase the set speed and gapsetting when you switch the system off.
Detection Issues
WARNING: On rare occasions,detection issues can occur due to the roadinfrastructures, for example bridges,tunnels and safety barriers. In these cases,the system may brake late orunexpectedly. At all times, you areresponsible for controlling your vehicle,supervising the system and intervening, ifrequired.
WARNING: If the systemmalfunctions, have your vehicle checkedas soon as possible.
The radar sensor has a limited field of view.It may not detect vehicles at all or detect avehicle later than expected in somesituations. The lead vehicle graphic does notilluminate if the system does not detect avehicle in front of you.

Detection issues can occur:
With vehicles that edge into yourlane that can only be detectedonce they have moved fully intoyour lane.
A
With motorcyclists that may bedetected late, or not at all.B
With vehicles in front of you whengoing into and coming out of abend. The detection beam doesnot follow sharp curves in the road.
C
In these cases, the system may brake late orunexpectedly. You should stay alert and takeaction when necessary.
If something hits the front end of your vehicleor damage occurs, the radar-sensing zonemay change. This could cause missed orfalse vehicle detection.
System Not Available
Conditions that can cause the system todeactivate or prevent the system fromactivating when requested include:
•A blocked sensor.
•High brake temperature.
•A failure in the system or a relatedsystem.
Blocked Sensor
A message displays if something obstructsthe radar signals from the sensor. Thesensor is in the lower grille. The systemcannot detect a vehicle ahead and does notfunction when something blocks the sensor.
Note:You cannot see the sensor. It is behinda fascia panel.
Keep the front of your vehicle free of dirt,metal badges or objects. Vehicle frontprotectors and aftermarket lights may alsoblock the sensor.

Possible Causes and Actions for This Message Displaying:
ActionCause
Clean the grille surface in front of the radar or remove the objectcausing the obstruction.The surface of the radar is dirty or obstructed.
Wait a short time. It may take several minutes for the radar to detectthat it is free from obstruction.The surface of the radar is clean but the message remains in thedisplay.
Do not use the system in these conditions because it may not detectany vehicles ahead.Heavy rain or snow is interfering with the radar signals.
Do not use the system in these conditions because it may not detectany vehicles ahead.Water, snow or ice on the surface of the road may interfere with theradar signals.
Wait a short time or switch to normal cruise control.You are in a desert or remote area with no other vehicles and noroadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no actual block. A false blocked condition either selfclears, or clears after you restart your vehicle.
