Electronic
Stabilization
Control
(ESC)
Description
ESC helps to imp rove
roa
d hold ing and vehicle
dynamics to help reduce the probab ility of skid-
d ing and loss of veh icle control. It works only
when the engine is runn ing
.
ESC detects certain
d iffic ult dr iving situat io ns, including when the
ve hicle is begin ning to spin (yaw) out of contro
l
a
nd
helps you to ge
t
the veh icle back under con
-
trol by se lectively braking the wheels, and/or re-
ducing engine powe
r
and providing steering as-
sistance to help hold the vehicle on the driver's
intended course. The indicator light
GI
in the in-
strument cluster blinks when ESC is tak ing action
t
o he lp you contro
l
the vehicle.
ESC has lim itations. It is important to remembe
r
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 sudde
n
change
in
the
coeff icie nt of fr iction of the road surface. W hen
there is a se ction of dry road
t
ha
t
is sudde nly cov-
e red with water, slush
or
snow
,
ESC
ca
nnot pe r-
form the same way
it
wou
ld
on the
dr
y surface. If
the vehicle hydrop lanes (rides on a cushion of wa-
ter instead of t he road su rface), ESC wi
ll
not be
ab le to he lp you stee
r
the veh icle because contact
with the pavement has been inter rupted and the
ve hicle cannot be braked or steered
.
During fast
cornering, part icu larly on w inding roads, ESC
can not always deal as effect ive ly w it
h
difficult
d riving situat ions
t
han
at
lowe
r
speeds
.
When
towi ng a
trail
e
r,
ESC
is not able to help you re-
gai
n con
t
rol as it would if you we re not
t
owing a
tra ile r.
Always
adju
st yo ur speed and driving sty le
t
o

,
tr affic
a

r
cond itions. ESC canno
t
override the vehicle's phys ical lim its, incre
a
se the
170
available tract ion, or keep a vehicle on
t
he road
if
road depa rt ure is a res ult of d river inattention
.
Instead, ESC improves the poss ibility of keeping
the ve hicle unde
r
contro
l
and on the road d
ur
ing
extreme maneuvers by us ing the driver's steer ing
inputs to help keep the vehicle going in the
in-
tended direction
.
If you are
t
raveli ng at a speed
t hat causes you to run off
t
he road before ESC
can provide any assista nce, you may not exper i-
ence the benefi
t
s of ESC.
ESC is switched on all the
t
ime. In certa in s itua-
tions when you need less tract ion, yo
u
can sw itch
off

by press ing the button

The following systems a re
int
egrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when
braki ng
.
The vehicle can st ill be steered even d ur-
ing hard braking
.
Apply steady pressure to the
brake peda
l.
Do not pump the pedal. A puls ing in
t he
bra
ke pedal indica
t
es th at

e system is help
-

o
bra
ke t he ve hicle.
Brake assist system
The bra ke assist system can decrease braking dis-
ta nce. It increases braking powe
r
whe
n
the dr iver
presses t he
br
ake peda
l
quickly
in
emergency sit-
uat io ns.
You

wit

tive cr uise con
t
rol *, the brake assist
syst
em is
more sensitive if t he distance detected to the ve-
hicle ahead is too sma ll.
Anti-slip regulation (ASR)

Electronic differential lock (EDL)
