Driving off
When driv ing off, always be sure to keep road
conditions in mind as you accelerate. If one
drive wheel spins because it is on a surface
with less grip, apply
plenty of
thrott le until
the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads on this whee l, the EDL cuts out tempo -
rarily. The vehicle remains operational and be-
haves in the same way as a veh icle w ithout
EDL.
As soon as the brake has cooled down, EDL
switches on again automatically .
Electronic lim ited slip differ ential
I n vehicles with front wheel drive*, an elec-
tronic li mited sli p differential engages when
driving on curves. The brakes are app lied spe-
cifically to the front wheel that is on the in-
side of the curve. This minimizes sliding on
the front wheels and enables precise and neu-
tral driv ing through curves. The electronic lim-
ited slip differential does not engage when
driving in wet conditions or snow.
A
WARNING
- When accelerating on sli ppery surfaces,
such as on ice or snow, always be careful
when depressing t he accelerator pedal.
Even wit h the EDL and the elect ronic lim-
ited slip differential wo rking, the drive
wheels can spin and reduce your ability
to control your car. Risk of crash!
- The increased safety afforded by EDL and
the electronic limited slip differential
does not mean that you can take safety
risks. Always adapt your dr iving sty le to
the road conditions and traff ic situat ion.

Tips
If a fa ult occurs in the ABS, the EDL is also
not f unction ing. This is indicated by the
ABS warn ing light¢

Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating .
General note s
The Anti-Slip Regulation System (ASR) is inte-
grated in the electronic stab ilizat ion program
(ESP). When the veh icle starts up and acceler-
ates, the wheels are prevented from spinning
by adjust ing the engine power to match the
amount of grip available fro m the road sur-
f ace.
How the system works
ASR performs automat ically, i.e. w it hout the
drive r's intervention . With the aid of the ABS
sensors ¢
page 203,
ASR monito rs the speed
of the dr iven whee ls. If the whee ls sta rt to
spin, engine to rque is reduced automat ically
unt il t he t ires f ind enough grip to lock onto
the road surface. The system is active across
the entire speed range.
The ASR works in conj unction with the ABS. If
a mal f unct ion shou ld occur in the ABS, the
ASR wi ll also be out of action .
Activating
The ES P is automat ically act ivated when t he
engine is sta rted and it performs a self-test .
You can activate a deact ivated ASR if requ ired
by pressing the
¢ page 199, fig. 194
button .
When it is act ivated, the message ESP / ASR
on appears brief ly in the display.
Deactivating
You can deact ivat e the ASR if required by
pressing t he button (f or less t han 3 seconds)
¢
page 199, fig. 194 .
With the ASR deact ivat-
ed, the ESP check light comes on, see
¢
page 15.
The message ASR off appears in
the display as well. The ASR can be deact ivat-
ed at any speed.
The ASR shou ld normally be activated all the
time . Only in certain exceptional situations
when some slip is desirable does it make
sense to deact ivate the ASR. Examples:
