Electronic Stability Control (ESC)
Description
EI ESC helps to improve safety. It reduces the tendency to skid and improves
the stability and roadholding of the vehicle. EI ESC detects critical handling
situations, such as vehicle understeer or oversteer, or wheelspin on the
driving wheels. It stabilises the vehicle by braking individual wheels or by
reducing the engine torque. The warning lamp will flash on the instrument
panel when the ESC is intervening .
ESC includes the Anti-lock brake system (ABS), the brake assist system, the
traction control system (ASR), electronic differential lock (EDL), electronic
self-locking*, selective torque control* and tractor-trailer sway mitigation*.
ESC also helps stabilise the vehicle by changing the torque.
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 ABS is
working.
Brake assist system
The brake assist system can reduce the required braking distance. The brak-
ing 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.
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 wheel. This function is available up to a speed
of around 100 km/h, 62 mph).
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.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control the following: Tractor-trailers
tend to sway. When the swaying of the trailer is felt by the vehicle and de-
tected by the ESC, it will automatically brake the towing vehicle within the
limits of the system and mitigate the sway. Tractor-trailer sway mitigation is
not available in all countries.
Electronic self-locking*/Selective torque control*
When driving around bends, an electronic self-locking intervenes. The front
wheel on the inside of the curve, or the two inside wheels, respectively, are
selectively braked as required. This minimises the traction of the front
wheels, allowing you to take bends with greater precision and neutrality. In
certain circumstances, where roads are wet or snow-covered, the respective
system may not intervene.
