If speed is increased by pressing the accelerator
pedal before the button is pressed, the vehi-cle's speed when the button is pressed will
become the set speed assuming that the accel-erator pedal is still depressed when the button ispressed.
A temporary increase in speed, such as whenpassing another vehicle, does not affect the CCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released. Alwaysobserve posted speed limits.
Engine braking instead of applying the
brakes
CC regulates speed by applying the brakeslightly. To avoid a loss of speed when drivingdown hills, use the engine braking functioninstead of letting the CC apply the brakes. In thissituation, the driver can temporarily deactivate theCC braking function.
To do so:
–Press the accelerator pedal approx. halfwaydown and release it.
>CC will automatically deactivate the auto-matic brake function and will then onlyuse the engine braking function.

WARNING
When ACC is in standby mode, the driver hasto control the vehicle's speed and distance toa vehicle ahead.
When ACC is in standby mode, the driver willbe alerted if the distance to the vehicle aheadis too short by the Distance Alert function.See the article "Distance Alert" for additionalinformation.
Standby mode due to action by the driver
ACC is temporarily deactivated and put instandby mode if:
•the brakes are applied
•The gear selector is moved to N
•the vehicle is driven faster than the setspeed for more than 1 minute.
In these cases, the driver will have to regulate thevehicle's speed.
A temporary increase in speed, such as whenpassing another vehicle, does not affect the ACCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released.
Automatic standby mode
ACC interacts with other systems, such asElectronic Stability Control. If any of these othersystems are not functioning properly, ACC willturn off automatically.
WARNING
If this happens, the driver will be alerted by anaudible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
ACC switches automatically to standby mode if:
•the vehicle's speed goes below approx.3 mph (5 km/h) and ACC cannot determineif the vehicle ahead is stationary or is anobject such as a speed bump, etc
•the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow
•the driver opens the door
•the driver unbuckles the seat belt
•the engine speed (rpm) is too high/low
•the wheels lose traction
•the brake temperature is too high
•the parking brake is applied
•the stability system's ESC Sport Mode isactivated
•the Off Road drive mode is selected
•The radar sensor is covered by e.g., wet snowor if heavy rain interferes with radar waves

Pilot Assist-1*
The Pilot Assist feature helps keep the vehicle inits current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
Function
The vehicle's camera monitors the traffic lane'sside marker lines and a distance monitor helpsmaintain the set time interval to the vehicleahead.
Pilot Assist helps provide more relaxed driving inheavy, slow-moving traffic at speeds up to30 mph (50 km/h) on highways and major roads.
Function overview
Windshield module containing the camera/radar sensor
Monitoring distance
Monitoring side marker lines
The driver sets the desired time interval to thevehicle ahead. Pilot Assist monitors that vehicleand the traffic lane's side market lines using thecamera and radar sensor mounted in the upper,center section of the windshield. It helps maintainthe set time interval by automatically adjustingspeed and by providing steering assistance tohelp keep your vehicle in the lane.
Pilot Assist's steering assistance is based onmonitoring the direction of the vehicle ahead andthe traffic lane's side marker lines. The driver canalways override Pilot Assist and steer the vehicleto e.g., change lanes, etc.
