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:
when driving with snow chains
in deep snow
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
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.
iWhen the ESP
® is switched off and one
or more drive wheels are spinning, the
v ABS/ESP® warning lamp in the
instrument cluster flashes. However,
the ESP
® will then not stabilize the ve-
hicle.
