ESP increases the car's stability. It reduces the tendency to skid and improves the stability and roadholding of the vehicle. ESP detects critical handling situations, such as understeer, oversteer and wheelspin on the driven wheels. It stabilises the vehicle by braking individual wheels or by reducing the engine torque. The indicator lamp 
in the instrument cluster starts flashing as soon as the ESP intervenes.
in the instrument cluster starts flashing as soon as the ESP intervenes.The ESP incorporates the functions of the anti-lock brake system (ABS), the brake assist system, the traction control system (ASR), the electronic differential lock (EDL), the dynamic steering* and the downhill assist function.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking until the vehicle has reached a virtual standstill. You can continue to steer the vehicle even when the brakes are on full. Keep your foot on the brake pedal and do not pump the brakes. You will feel the brake pedal pulsate while the anti-lock brake system is working.
Brake assist system
The brake assist system can shorten the braking distance. The braking force is automatically boosted if you press the brake pedal quickly in an emergency. You must keep pressing the brake pedal until the danger has passed. On vehicles with adaptive cruise control*, the response of the brake assist system will be more sensitive if you are too close to the vehicle in front.
Traction control system (ASR)
In the event of wheelspin, the traction control system reduces the engine torque to match the amount of grip available. This helps the car to start moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the spinning wheel and directs the power to the other driven wheels. This function is active up to about 125 km/h.
To prevent the disc brake of the braked wheel from overheating, the EDL cuts out automatically if subjected to excessive loads. The vehicle can still be driven. The EDL will switch on again automatically when the brake has cooled down.
Dynamic steering*
On vehicles with dynamic steering*, the ESP can also intervene in the steering to stabilise the vehicle in critical situations.
WARNING!
- The grip provided by the ESP, ABS, ASR, EDL and dynamic steering* systems is still subject to the physical limits of adhesion. Always bear this in mind, especially on wet or slippery roads. If you notice the systems cutting in, you should reduce your speed immediately to suit the road and traffic conditions. Do not let the extra safety provided tempt you into taking any risks when driving - this can cause accidents.
- Please remember that the accident risk always increases if you drive fast, especially in corners or on a slippery road, or if you follow too close behind the vehicle in front of you. Please bear in mind that even ESP, ABS, brake assist, EDL, ASR and dynamic steering* cannot compensate for the increased accident risk.
- When accelerating on a uniformly slippery surface (for instance all four wheels on ice or snow), press the accelerator gradually and carefully. The driven wheels may otherwise start to spin (in spite of the integrated control systems), which would impair the car's stability and could lead to an accident.
Note
- To ensure that the ASR works properly, all four wheels must be fitted with identical tyres. Any differences in the rolling radius of the tyres can cause the system to reduce engine power when this is not desired.
- Should a malfunction occur in the ABS or EDL, both the ABS indicator lamp
and the ESP indicator lamp Link will light up. - In the event of a malfunction in the ESP system, the ESP warning lamp Link will light up.
- If a malfunction should occur in the ABS, the ESP, EDL and ASR will also be out of action.
- The systems can make noises when they intervene.
- When the roof carrier cross bars supplied with your vehicle are attached to the roof railings, the ESP is adapted to the change in the centre of gravity of the vehicle caused by any loading of the vehicle.
