ESC includes and/or works together with the
anti-lock braking system (ABS), brake assist
system, anti-slip regulat ion (ASR), electronic
differential lock (EDL), dynamic steering* and
electronic interaxle differential lock*. ESC is
switched on all the time. In certain situations
when you need less tract ion, you can switch
off ASR by pressing the button above
~ page 201, fig. 188 the selector lever. Be
sure t o switch ASR on again when you no lon-
ger need less traction.
Anti -lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even du ring hard braking . Apply steady pres-
sure to the brake pedal. Do not pump the ped-
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease brak ing
distance. It increases braking power when the
driver presses the brake pedal quickly in emer-
gency situations. You must press and hold the
brake pedal until the situation is over. In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti- slip regulati on (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic diff erential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all whee l drive*. This funct ion is available up
to about 7S mph (120 km/h).
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL will switch on again au-
tomatically when conditions have returned to
normal.
Dynamic st eering *
On vehicles with dynamic st eering, ESC helps
stabilize the steering in certain situations.
Electronic interaxle differential lock
function*
The electronic interaxle differentia l lock f unc-
tion activates when driving thro ugh curves.
Braking is targeted toward the wheels on the
inside of the curve as needed. This helps to
minimize front whee l skid, improves traction
and allows for more precise driving through
curves.
A WARNING
- ESC, ABS, ASR, EDL, dynamic steering*
and the electronic interaxle differential
lock function* cannot overcome the laws
of physics. This is especially impo rtant
on slippery or wet roads.
If the systems
begin acting to stabilize your vehicle, you
should immediately change your speed
to match the road and traffic conditions .
Do not let the increased safety provided
by these systems tempt you to take risks.
Doing so will increase the risk of a loss of
vehicle control, collision and serious per-
sonal injur ies.
-Always adapt your speed to road, traffic
and weather conditions. The risk of los-
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake assist sys-
tem, EDL, ASR, dynamic steering * and
the electron ic interaxle differential lock
function* cannot prevent collisions.
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance systems that cannot al-
ways help to reduce the risk of loss of ve-
hicle control.
