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 sur-
faces for better grip such as:
starting out on slippery surfaces and
in deep snow in conjunction with
snow chains
in sand or gravel
When 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
!
Because of the ESP’s automatic oper-
ation, the engine must be shut off
(SmartKey in starter switch position 0
or 1) when
the parking brake is being tested
on a brake test dynamometer
the vehicle is being towed with
the front/rear axle raised.
Active braking action through
the ESP may otherwise seriously dam-
age the brake system.
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 driv-
ing maneuvers.
i
When the ESP is switched off and one
or more drive wheels are spinning,
the ABS/ESP warning lamp v in the
speedometer flashes. However, the
ESP will then not stabilize the vehicle.
