Electronic Stability Control (ESC)
Electronic Stability Control (ESC) helps reduce wheel spin, counteract skidding and to generallyhelp improve directional stability.
A pulsating sound will be audi- ble when the system is activelyoperating and is normal. Accel-eration may also be slightlyslower than normal.
WARNING
ESC is a supplementary aid and cannot deal with all situations or road conditions. The driver is always responsible for operating the vehicle in a safe manner in accordancewith current traffic regulations.
ESC consists of the following functions: • Traction control
• Spin control
• Active Yaw Control
• Engine Drag Control
• Trailer Stability Assist
Traction controlThis function is designed to help reduce wheel spin by transferring power from a drive wheel that begins to lose traction to the wheel on the oppo-site side of the vehicle (on the same axle).
Spin controlThis function is designed to help prevent thedrive wheels from spinning while the vehicle isaccelerating.
Active Yaw ControlAt low speeds, this function helps maintain direc-tional stability by braking one or more of thewheels if the vehicle shows a tendency to skid orslide laterally.
Engine Drag Control EDCEDC helps keep the engine running if the wheelsshow a tendency to lock, e.g., when shifting downin the manual shifting mode or while using theengine's braking function on a slippery surface. Ifthe wheels were to lock, the vehicle wouldbecome more difficult to steer.
Trailer Stability Assist
*1TSA helps stabilize a vehicle that is towing atrailer when the vehicle and trailer have begun tosway. This system is automatically deactivated if the driver selects
Sport mode.

Changing Cruise Control speed
Changing a set speed
Function buttons and symbols (generic illustration)
–Change a set speed by pressing the (1)
or — (3) buttons briefly or by pressing and
holding them:
• Press briefly
: changes speed in
+/– 5 mph (+/– 5 km/h) increments. Each press changes the vehicle's speedby +/– 5 mph (+/– 5 km/h).
• Press and hold
: changes the speed
+/– 1 mph (+/– 1 km/h) at a time.Release the button when the set speedindicator (4)/(6) has moved to the desiredspeed.
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 when passing 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. halfway down and release it.
> CC will automatically deactivate the auto- matic brake function and will then only use the engine braking function.

WARNING
•Poor weather or winding roads can affect the radar sensor's capacity to detect vehi-cles ahead.
• A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorterdistance than the one that has been setor not illuminating at all.
• High speeds may also result in the warn-ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.
For additional information, see also the article"Radar sensor limitations."

Adaptive Cruise Control (ACC) *
ACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead.
ACC helps provide more relaxed driving on long trips on highways or other major roads in a rela-tively even flow of traffic.
The camera and radar sensor monitor the distance to the vehicle ahead (generic illustration - certain detailsmay vary from model to model)
The driver sets that desired speed and time inter- val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed. ACC is designed to follow a vehicle ahead in the same lane and maintain a time interval to that vehicle set by the driver. If the radar sensor doesnot detect a vehicle ahead, ACC will insteadmaintain the speed set by the driver. ACC is designed to smoothly regulate speed. However, the driver must apply the brakes in sit-uations that require immediate braking such aswhen there are great differences in speedbetween vehicles, or if the vehicle ahead brakessuddenly. Due to limitations in the radar sensor,braking may occur unexpectedly or not at all. Adaptive Cruise Control can follow another vehi- cle from a standstill up to 125 mph (200 km/h).Always observe posted speed limits. The driver can also toggle between ACC and Cruise Control (CC) – see the article "Switchingbetween Cruise Control and Adaptive CruiseControl".
