Intelligent Technology Electronic Stabilization
Control (ESC)
Description
Elect ronic stabili zation control ( ESC) supports
driver safety. It red uces the risk of slipping and
improves dr iving stabi lity. ESC detects crit ica l sit­
uations such as the vehicle overstee ring and un­
dersteeri ng or the w heels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
i n g e ngine torque . When the ESC engages, the
G1 indicato r light bli nks in t he instr ument clus­
t er.
The fo llow ing systems are in tegrated in the ESC:
Anti-lock braking system (ABS)
ABS p reve nts the whee ls from lock ing whe n brak ­
ing. The vehicle can st ill be steered even d uring
hard brak ing. Apply steady press ure to the bra ke
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is act ing to
s tabili ze the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It inc reases brak ing power when the d river
presses the brake pedal q uick ly in eme rgency sit­
uations . You must press and hold t he b rake pedal
until the dangerous si tuatio n is ove r. In veh icles
w ith adapt ive c ruise con trol*, the bra ke assist
sys te m is more sensitive if t he di stan ce detec ted
t o the veh icle dr iv ing ahead is too small.
Anti-Slip Regulation (ASR)
ASR reduces eng ine power when the drive wheels
beg in s pinning a nd adapts the force to the road
conditions . T his makes it easie r to sta rt, acceler­
a te and dr ive u p hill s.
Electronic differential lock (EDL)
The EDL applies the brakes to a whee l t h at starts
sp inning and transfe rs t he d rive power to t he
other d riving wheel or wh eels ( if the veh icle is
eq uipped w ith all whee l dr ive*) . T his func tion is
no t a vailable at hig her s pee ds .
148
In extreme cases, ED L automat ica lly swi tches off
to keep the b rake o n the bra ked whee l from over ­
h eating. The ve hicle is still wo rking co rrect ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Power steering
The ESC can also support veh icle sta bility
th ro ugh stee ring .
Selective wheel torque control
Selective w heel to rque cont rol is used when driv­
in g on curves. The fron t whee l on the in side of
t h e curve or both whee ls on t he i nsid e of the
cu rve are braked se lective ly as needed. This al ­
l ows mo re precise driving in cu rves .
Automatic post-collision braking system
The "automat ic pos t-coll is io n braking syste m"
c a n help t o reduce t he risk of sliding and of addi ­
tion al collisions a fter an acc iden t. If the a irbag
contro l modu le detects a collision above a certa in
vehicle speed, the ve hicle is braked by the ESC.
The
ve hicle does not br ak e automatically if;
- t he dr ive r presses the acce lerato r pedal, or
- the ESC, the b ra ke system or the ve hicle elect ri-
cal sys tem are not func tioning .
A WARNING
-The ES C and i ts in tegra ted systems can not
over co m e the li mits im posed by n atural
p hy sical laws. T h is is es peci ally i mpo rtan t
on s lippery or we t ro ad s. If the sy stem s be­
gi n acting to stabilize yo ur vehicle, you
should immediately a lter your speed to
match the road and t raffic conditions. Do
not let the increased safety provi ded tempt
you into tak ing risks. This could increase
your r is k of a coll is io n.
- Please note the r is k of a coll is io n increases
when dr iv in g fast , especially t hrough c urves
and on s lippery or wet roads, and when dr iv­
ing too close to obj ects ahead . T he ESC and
