Electronic stabilization
control (ESC)
Description
Electronic Stabilization Control (ESC) supports
driver safety.
It reduces the risk of slipping and
improves driving stability. ESC detects critical sit
uations such as the vehicle oversteering and un
dersteering or the wheels are spinning. The vehi
cle is stabilized by applying the brakes or reduc
ing engine torque. When ESC engages, the
G1 in
dicator light blinks in the instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit
uations . You must press and hold the brake pedal
until the dangerous situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler
ate and drive up hills .
Electronic differential lock (EDL)
EDL applies the brakes to a wheel that starts
spinning and transfers the drive power to the
other driving wheels. This function is not availa
ble at higher speeds.
In extreme cases, EDL automatically switches
off
to keep the brake on the braked wheel from over heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi
tions have returned to normal.
88 Steering
recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv
ing on curves. The front whee l on the inside of
the curve or both wheels on the inside of the
cu rve are braked selectively as needed. This al
lows more precise driving in curves. The applica
ble system may not activate when driving in wet
or snowy conditions.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits imposed by natural physical laws. This is especially important
on slippery or wet roads. If the systems be
gin acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt
you into taking risks. This could increase
your risk of a collision .
- Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv ing too close to objects ahead. The ESC and
its integrated systems cannot always pre
vent collisions -there is still a risk of acci
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal
led and this can affect driving stability and
increase the risk of a collision.
(j) Tips
-The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de
scribed are working.
