214 Driving and Driving Safety
Off-road PSM
(PSM in Low Range program)
When Low Range is active, an off-road PSM
specially matched to off-road driving is activated
to enhance traction.
In order to improve driveability on difficult terrain,
the response of the off-road PSM is less sensitive
in the low speed range when the vehicle is opera-
ted in the Low Range off-road driving program.
If the brakes are highly stressed, the automatic
brake differential (ABD) switches itself off to
protect the brakes. It remains deactivated until the
brake system has cooled sufficiently.
Engine drag torque control
In conditions of excessive slip, the engine drag
torque control system prevents all driven wheels
from locking up when the car is overrunning. This
is also the case for downshifts on a slippery road.
Switching off PSM
f Press PSM OFF button A.
PSM is switched off after a short delay.
The light-emitting diode in the button is lit up.
When the PSM is switched off, the multifunctio-
nal PSM light on the instrument panel is lit and
a message appears in the multi-purpose dis-
play of the instrument panel.
During braking, the vehicle is stabilized even
when PSM is switched off.
One-sided spinning of the wheels is prevented,
even with PSM switched off.
PSM should always be switched on during
“normal” driving.
However, it can be of advantage to switch off PSM
temporarily in exceptional situations:
On a loose surface or in deep snow
When “rocking the vehicle free”
When using snow chains.
Vehicles with Tiptronic: When the PSM is
switched off the slip monitoring function is also de-
activated.
