Switching off the ESP
To improve the vehicle’s traction, turn off
the ESP in driving situations where it would
be advantageous to have the drive wheels
spin and thus cut into surfaces for better
grip such as:
starting out on slippery surfaces and in
deep snow in conjunction with snow
chains
sand or gravel
when driving off-roadWhen the ESP is turned off,
engine torque is not limited.
the drive wheels can spin.The ESP control switch is located in the up-
per center console.
ESP on/off
Press upper half of switch.
ESP is deactivated and the ESP warning
lamp v in the instrument cluster
comes on.
Warning!G
The ESP should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.!
Avoid spinning of a drive wheel for an
extended period of time with the ESP
switched off. This may cause serious
damage to the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
i
Turn ESP on immediately if the afore-
mentioned circumstances do not apply
anymore.
