(ESC)
Description
Electronic Stabilization Control (ESC) support s
driver safety.
It
reduces the risk of slipping and
improves dr iving stability. ESC detects crit ical 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 inst rument cluste r.
The fo ll ow ing systems are integrated in the ESC:
Anti -lock braking system (ABS)
ABS prevents the whee ls from locking when brak-
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A puls ing 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 brak ing power when the driver
presses the brake pedal quick ly in emergency sit-
uations . You must press and hold the brake pedal
until the dangerous situat ion is over.
Ant i-slip regulation (ASR)
ASR reduces engine power when the drive w heels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler-
ate and dr ive up hil ls.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with all
wheel drive*) . This funct ion is not available 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 work ing correctly. EDL
92
will switch on again aut omatically when condi -
tions have returned to normal.
Steering recommendation
The ESC helps t o st abili ze t he vehicle by changing
t he st eering torque .
Selective wheel torque control
Selective wheel to rque cont rol is used when driv-
ing on curves. The front whee l on the inside of
t he curve or both wheels on the inside of th e
curve are braked selective ly as needed. This al-
lows mo re precise driving in curves.
Automatic post-collision braking system
The "automat ic post -coll ision braking system"
can help to reduce the risk of sliding and of addi-
tiona l collisions after an accident. If the air bag
contro l modu le detects a collision above a cert ain
vehicle speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if:
- the drive r presses the accelerator pedal, or
- the braking force generate d by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle elect ri-
cal system are not functioning.
A
WARNING
- The ESC and its integ rated systems cannot
overcome the lim its imposed by natura l
physical laws. This is especially impo rt ant
on sl ippery or wet roads. If the systems be-
gi n act ing t o stabili ze your vehicle, you
should immedi ately alte r your speed t o
match t he road and t raffic conditions . Do
not let t he increased safety provi ded tempt
you into taking risks . This could increase
your risk of a coll ision.
- Please note the risk of a coll ision increases
when dr iving fast, especially th rough curves
and on slippery or wet roads, and when dr iv-
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre-
vent collisions - t here is st ill a risk of acci-
dents!
