ESP warning lamp ä flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.

prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESP cannot
prevent accidents resulting from excessive
speed.
! Vehicles without 4MATIC: switch the
ignition off when:
R the parking brake is being tested using a
dynamometer
R
the vehicle is being towed with the front/
rear axle raised
Application of the brakes by ESP ® may
otherwise destroy the brake system.
! Vehicles with 4MATIC: switch off the
ignition when the parking brake is being
tested on a brake dynamometer.
Application of the brakes by ESP
® may
otherwise destroy the brake system.

operate the vehicle on such a
dynamometer, please consult an

ETS/4ETS (Electronic Traction System)
G WARNING
Observe "Important safety notes"
(
Y page 61).
Traction control is part of ESP ® .
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. On vehicles with 4MATIC, more
drive torque is also transferred to the wheel
or wheels with traction.
Traction control remains active if you
deactivate ESP
® .
Deactivating/activating ESP ®
i Observe the "Important safety notes"
section ( Y page 61).
G WARNING
ESP ® should not be deactivated during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not deactivate ESP
® when the emergency
or spare wheel is mounted.
ESP ® is activated automatically when the
engine is started.
It may be best to deactivate ESP
® in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravel
G WARNING
Switch on ESP ® immediately if one of the
previously stated conditions is no longer met.
