When the ESP system is activated, the traction indicator on the dashboard starts flashing.
When only the traction control system, which is part of the ESP system, is turned on, the traction loss indicator also starts flashing.
If the road grip deterioration indicator is flashing, it means that the vehicle is moving on a slippery road.
Indicators:
- If the normal functioning of the ESP system is disturbed, the road grip deterioration indicator and the dynamic stabilization system deactivation indicator located on the instrument panel light up.
- As long as these indicators are lit, the vehicle's dynamic stabilization system will not function.
Vehicle dynamic stabilization system (ESP) uses a braking system for a slipping drive wheel «Brake Limited Slip Differential» (BLSD) in order to improve the traction properties of the car. The BLSD system works when one of the wheels begins to spin on a slippery surface. The BLSD system, by braking the slipping wheel, provides a corresponding increase in torque on the other wheel of the axle, which has better grip on the ground.
When the ESP system is disabled, none of the functions of this system will operate. When the ESP system is disabled, the BLSD and ABS systems continue to operate. When the BLSD or ABS system is activated, the indicator flashes, a characteristic noise is heard and / or a pulsation is felt on the brake pedal. These symptoms are not indicative of any malfunction.
Usually, when the ESP is turned on, a slight vibration is felt on the brake pedal, which is accompanied by a characteristic noise from the modulator located under the hood. These vibrations and noises are an external manifestation of the functioning of the ESP and indicate the health of the dynamic stabilization system.
ESP failure diagnostics are performed by the control unit each time the engine is started while the vehicle is moving at low speed forward or reverse. During this self-test, you may hear a characteristic noise and/or feel a slight pulsation on the brake pedal. These symptoms are not indicative of any malfunction.
Note:
Under normal driving conditions, the ESP system should be on. However, sometimes it is advisable to turn it off to allow some wheel slip:
- - when driving in deep snow or mud; when trying to free a car stuck in the snow; when driving with snow chains.
Dynamic stabilization switch (ESP)
Dynamic stabilization system (ESP) should be enabled under normal driving conditions.
However, when driving in deep snow or wet ground, the ESP system reduces engine power (even with the maximum pressure on the accelerator pedal), trying to reduce wheel slip. The engine speed will be reduced even when the accelerator pedal is fully depressed. If you need maximum power to get the stuck car out, disable the ESP system.
To disable the ESP system, press the switch shown in the figure. This will turn on the indicator.
