ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys-
tem, anti -slip regulation (ASR) , electronic dif-
ferential lock (EDL), dynamic steering* and
electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain situations when you need
less traction, you can switch off ASR by press-
ing the butto n ~~

175. Be sure to switch ASR
on again when you no longer need less trac-
tion.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even during hard braking . Apply steady pres-
sure to the brake pedal. Do not pump the ped-
al. A pulsing in the brake pedal indicates t hat
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease bra king
distance. It increases braking power when the
driver presses t he brake pedal quick ly in emer-
gency situations . You must press and hold the
brake pedal until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
distance detected to the veh icle 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 diffe renti al lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-

tomat ically when conditions have returned to
norma l.
Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab ilize the st eering in crit ical sit uat ions.
Electronic interaxle differential lock*/
selective wheel torque control*
The electronic interaxle differential lock (front
whee l dr ive) or the selective whee l to rque
control (all-whee l dr ive) opera t es when dr iv-
ing thro ugh curves. The front wheel on the in-
side of the curve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
curves. The applicable system may not acti-
vate when dr iving in wet or snowy conditions.
A
WARNING
- ESC, ABS, ASR, EDL dynam ic steering*
and the elect ronic interaxle differential
lock* /se lective wheel torque control*
cannot overcome the laws of physics.
This is especially important on slippery
or wet roads. If the systems begin acting
to stabilize your veh icle, you should im-
mediately change your speed to match
the road and traff ic 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
veh icle contro l, col lision and serious per-
sonal injuries.
- Always adapt your speed to road, traffi c
and weat her conditions. The risk of los-
ing cont rol of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when dr iving too close to vehicles up
ahead. ESC, ABS, the brake assist sys-
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se-
lective whee l torque control* cannot pre-
vent collisions .
