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.
