Electronic Stability Control
The Electronic Stability Control (ESC1) functionhelps the driver avoid skidding and improves thevehicle's directional stability.
This symbol will be displayed inthe instrument panel when theESC system is intervening.
When the ESC has intervenedto apply the brakes, a pulsingsound may be heard and thevehicle may accelerate more slowly than expec-ted when the accelerator pedal is depressed.
The ESC system consists of the following sub-functions:
Stability control2
Spin control and active yaw control
Engine drag control
WARNING
The Electronic Stability Control systemESC is supplementary driver supportintended to facilitate driving and make itsafer – it cannot handle all situations inall traffic, weather and road conditions.
ESC is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Stability control 2
This function helps control the driving and brak-ing force of each individual wheel in an attemptto stabilize the vehicle.

Spin control and active yaw control
This function is active at low speeds and brakesthe wheels that are spinning to transfer additionalpower from wheels that are not spinning.
This function also helps prevent the wheels fromspinning while the vehicle is accelerating.
1Electronic Stability Control2Also called traction control.

Engine drag control
Engine drag control (EDC3) helps prevent inad-vertent wheel lock, e.g. after downshifting orusing engine braking when driving at low speedson a slippery surface.
Inadvertent wheel lock while driving could impairthe driver's ability to steer the vehicle.

The ESC4 system is always activated and can-not be switched off. However, the driver canselect ESC Sport Mode, which offers moreactive driving characteristics.
With the ESC Sport Mode sub-functionselected, intervention from ESC is reduced andmore lateral movement is permitted, giving thedriver more control of the vehicle than usual.
When ESC Sport Mode is selected, ESC mayseem to be disabled even though the functioncontinues to assist the driver.
ESC Sport Mode also helps provide maximumtraction if the vehicle gets stuck or is driving on aloose surface such as deep snow or loose sand.
