ASR switches on again automatically if you
drive faster than 60 km/h or the car en-
ters an unstable driving situation.
Electronic Stability Program (ESP
®
)
ESP
®
monitors driving stability and de-
tects a tendency of the vehicle to under-
steer or oversteer (skidding) in good time.
ESP
®
stabilises the vehicle by braking indi-
vidual wheels as well as limiting the engine
power output, and greatly assists you
when driving on wet or slippery road surfa-
ces. ESP
®
also stabilises the vehicle when
braking.
Warning lamp
v in the instrument clus-
ter lights up when ESP
®
is intervening.
G
Risk of accident
Proceed as follows if the v warning lamp
in the instrument cluster flashes:
I
Do not deactivate ASR under any cir-
cumstances.
I
Only depress the accelerator pedal as
far as necessary when pulling away.
I
Adapt your driving style to suit the pre-
vailing road and weather conditions.
Otherwise, the vehicle could start to skid.
ESP
®
cannot reduce the risk of an accident
if you drive too fast. ESP
®
is unable to over-
ride the laws of physics.
There is a malfunction if the # indica-
tor lamp is constantly lit when the engine
is running (
e page 270).
If ESP
®
malfunctions, engine power output
may be reduced.
! Only operate the vehicle briefly (maximum
of 10 seconds) on a brake dynamometer. The
key must be turned to position 1 in the ignition
lock during this time. You could otherwise dam-
age the drive train or the brake system.
! Do not operate the vehicle on a roller dyna-
mometer (e.g. for performance testing). If you
wish to operate the vehicle on a roller dyna-
mometer, please consult a Mercedes-Benz
Service Centre beforehand. You could other-
wise damage the drive train or the brake sys-
tem.
Electronic traction system (4-ETS)
Vehicles with 4x4 permanent four-wheel
drive are equipped with 4-ETS. The elec-
tronic traction system, 4‑ETS, is integrated
in the ESP
®
. It allows you to pull away or
accelerate on slippery surfaces by braking
the wheels individually when they start to
spin.
The
v warning lamp in the instrument
cluster flashes when at least one tyre has
exceeded its grip limit at any speed.
G
Risk of accident
When the v warning lamp in the instru-
ment cluster flashes,
I
only depress the accelerator pedal as far
as necessary when pulling away
I
ease off the accelerator pedal while you
are driving
I
adapt your driving style to suit prevailing
road and traffic conditions
Otherwise, the vehicle could start to skid.
If you drive too fast, 4-ETS cannot reduce
the risk of an accident.
i If you apply the brakes heavily, the per-
formance of 4-ETS will be reduced.
