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:
ț starting out on slippery surfaces and in
deep snow in conjunction with snow
chains
ț in sand or gravel
The switch is located in the lower part of
the center console.
1 ESP switch
̈ Press ESP switch 1 until the ABS/ESP
warning lamp v in the instrument
cluster comes on.
ESP is deactivated.
!
Because of the ESP’s automatic opera-
tion, the engine must be shut off
(SmartKey in starter switch position 0
or 1 or KEYLESS-GO* start/stop but-
ton in position 0 or 1) when
ț the parking brake is being tested on
a brake test dynamometer
ț the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
may otherwise seriously damage the
brake system.
The ESP will only function properly if
you use wheels of the recommended
tire size (
୴ page 378).
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.
!
Turn on the ESP immediately if the
aforementioned circumstances do not
apply anymore.
i
Distronic* cannot be activated when
the ESP has been deactivated.
