Electronic stabilization
control (ESC)
Description
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves dr iving stability. ESC detects crit ical sit­
uations suc h as the vehicle overstee ring and un­
de rs teer ing or the wheels are sp inning. The vehi­
cle is s tabilized by app ly ing the brakes or reduc­
i ng e ngine torque. Once t he ES C i s ac tiva ted, the
indicator light
DJ b li nks in the instrument clus ­
ter .
The fol low ing systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS preve nts the whee ls from lock ing whe n brak­
i ng. The vehicle can s till be steered even during
h a rd brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
bra ke pedal indica tes th at the system is act ing to
s tabili ze the vehicle.
Brake assist system
The brake assist sys tem can decrease braking dis­
tance .
It increases brak ing power when the d rive r
p resses the brake pedal q uic kl y in eme rgency sit­
uations. Yo u m ust press and hold the b rake pedal
u nti l the dangero us si tuati on is over. In ve hicles
with adaptive cruise contro l*, the bra ke assist
system is more sensitive if the d istance detected
to the veh icle ahead is too small.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin spinning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler ­
ate and drive up inclines .
Intelligent Technology
Electronic differential lock (EDL)
T he ED L brakes wheels t hat are spi nning and
transfe rs the drive power to the o ther dr ive
whee l or wheels if the vehicle is equ ipped with all
whee l drive *). T his function is not available at
higher speeds.
In extreme cases, ED L automat ica lly swi tches off
to keep the b rake o n the braked whee l from over­
heating. The vehicle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendation
T he ESC he lps to s tabilize the vehicle by changing
the steering torque.
Selective wheel torque control
Se lective w heel torque con trol is used w hen d riv ­
i ng on curves. The front whee l on the ins ide of
the curve or both wheels on t he i nsid e of the
c ur ve are braked se lective ly as needed . This al ­
lows more precise driving in c urves .
Automatic post -collision braking system
T he "Automat ic pos t-collis ion braki ng system"
ca n help to reduce the ris k of sliding and of othe r
collisions af ter an a cciden t. If th e ai rbag cont rol
module detects a collision above a certai n vehicle
speed, the vehicle is brake d by the ESC.
T he veh icle does not br ake au tomatic ally if:
- the dr iver presses the acce lera tor pedal, or
- the braking fo rce generated by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the brake system o r the veh icle electri­
cal system are not functioning.
A WARNING
- T he ESC and its i nteg rated systems ca nnot
over come the li mits posed by natu ral physi­
cal laws. This is espe cially impor tant on slip­
pery o r we t roads . If the systems beg in act­
ing to stabilize your veh icle, you should im ­
mediately a lter your speed to match the
road and tra ffic condit ions. Do not let the
increased safety provided tempt you into
