Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road ho ld ing and vehicle
dynamics to help reduce the probability of skid
d ing and loss of vehicle control. It works only
when the engine is runn ing . E SC detects certain
d ifficult dr iving sit uat ions, including when t he
ve hicl e is begin ning to spin (yaw) out of contro l
and helps you to ge t the veh icle back under con
tro l by se lective ly braking the wheels, and/or re
ducing engine powe r and provid ing steering as
sistance to help hold the vehicle on the dr iver's
intended course. The indicator light
GJ in the in
strument cluster blinks when ESC is taking action
to help you co ntrol the vehicle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not a lways be able to help out under all con
d itions you may come up aga inst. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coeff icient of friction of the road surface. When
there is a section of dry road that is sudde nly cov
e red with water, slush o r snow, ESC cannot pe r
form the same way it wo uld on the dry s urface . If
the vehicle hydrop lanes (rides on a cushion of wa
ter i nstead of the road su rface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been interrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, pa rticula rly on w inding roads, ESC
cannot always deal as effect ively w it h difficult
d riving si tuations tha n at lowe r speeds. When
tow ing a t raile r, ESC is not able to help you re
ga in con trol as it would if you we re not towing a
tra iler .
A lways adjust yo ur speed and driving sty le to
road, traffic and weathe r cond itions. ESC cannot
override the vehicle's physical lim its, increase the
Intellig ent Technology
available t ract ion, or keep a vehicle on the road if
road departure is a resu lt of driver inattention .
Instead, ESC improves the possib ility o f keeping
the vehicle under contro l and on the road d uring
extreme maneuvers by us ing the driver's steer ing
i nputs to help keep the veh icle go ing in the in
tended direction.
If you are traveling at a speed
that causes you to run off the road before ESC c an p rovide any assistance, you may not exper i
en ce the benefi ts of ESC.
ESC is switched o n all the time . In certa in s itua
t ions when you need less tract ion, you can sw itch
off AS R by press ing the button
[fil c:> page 152,
fig. 141. B e sure to switc h ASR on again whe n
you no longer need less tract ion .
T he following systems are integrated in the ESC:
Anti-lock brak ing system (ABS )
ABS prevents the wheels from locking when brak ing . The vehicle can still be steered even dur ing
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal ind icates that the system is acting to
stab ilize the ve hicle.
Brake assist system
The brake assist system can decrease braking dis
tance. It increases braking powe r when the dr iver
presses the brake peda l quickly in emergency sit
uat io ns. You must press a nd ho ld the bra ke pedal
u nt il the dange rous situation is over.
Anti-slip regulation (ASR)
ASR reduces engine power whe n the dr ive wheels
begin spin ning and adapts the force to the road
co ndit ions. This makes it eas ier to s tart, acce ler
ate and d rive up incl ines.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other dr ive
wheel or wheels if the vehicle is equ ipped with all
whee l drive*) . This function is not available a t
highe r speeds .
In extreme cases, EDL automat ica lly switches off
to keep t he brake o n the braked wheel from over
hea ting . T he veh icle is still working co rrectly. EDL.,.
