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.

Electronic Stability Control (ESC) sport mode
ESC is always activated and cannot be switched off.
However, the driver can select Sport mode,
which offers more active driving characteristics. In Sport mode, the engine management system
monitors movement of the accelerator pedal and steering wheel for sportier driving and allowsmore lateral movement of the rear wheels beforeESC is triggered. Under certain circumstances, such as when driv- ing with snow chains, or driving in deep snow orloose sand, it may be advisable to temporarily use Sport mode for maximum tractive force.
If the driver releases pressure on the accelerator pedal, ETC will also activate to help stabilize thevehicle.
Activating/deactivating Sport modeIn the center display's Function view, tap ESC Sport Mode.
The green indicator light in the button will illuminate to showthat the function has been acti-vated or gray when the functionis deactivated.
When Sport mode is activated, this
symbol will illuminate in the instrument panel. It will remain on until the driverdeactivates the function. ETC will also
return to normal mode when the engine is restar-ted.
