Driving safety systems
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
in sand or gravelWhen you switch off the ESP
the ESP does not stabilize the vehicle
the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for better grip
the traction control will still brake a
spinning wheel
the ESP continues to operate when you
are braking
Turn on the ESP immediately if the afore-
mentioned circumstances do not apply
anymore.The switch is located on the lower part of
the center console.
1ESP switch (off/on)
Press switch1.
The v ABS/ESP warning lamp in
the instrument cluster comes on.
The ESP is deactivated.
Warning!
G
ESP should not be switched off during nor-
mal driving other than in the circumstances
described below. Disabling of the system
will reduce vehicle stability in standard driv-
ing maneuvers.
iWhen the ESP is switched off and one
or more drive wheels are spinning, the
v ABS/ESP warning lamp in the in-
strument cluster flashes. However, the
ESP will then not stabilize the vehicle.
