– PSM actively stabilises the vehicle as required
during dynamic driving manoeuvres (e.g. rapid
steering movements, during lane changes or
on alternating bends).
– Improved braking stability on bends and on
different or varying road surfaces.
– It improves braking function and shortens
stopping distance in the event of emergency
braking (vehicles with four-wheel drive only).
Readiness for operation
PSM is switched on automatically every time you
start the engine.
PSM should always be switched on during
“normal” driving.
However, it may be advantageous to switch off
PSM temporarily in exceptional situations, for
example:
– On a loose surface or in deep snow,
– When “rocking the vehicle free” and
– When using snow chains.
Switching off PSM
f Press PSM OFF button.
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 multifunc-
tional PSM light on the instrument panel is lit
and a message is shown on the on-board
computer.
An acoustic signal also sounds.
When PSM is switched off, the additional braking
functions are deactivated. Automatic reactivation
in emergency situations is coupled to the PSM
control.
The following functions stabilise the vehicle in
emergency situations, even with PSM switched
off:
– When PSM is off, the vehicle is stabilised as
soon as one of the two front wheels enters the
ABS control range.
– When PSM is off and Sport mode is on, the
vehicle is stabilised as soon as both front
wheels enter the ABS control range.
One-sided spinning of the wheels is prevented,
even with PSM switched off.
Switching PSM back on
f
Press PSM OFF button.
PSM is switched on after a short delay.
The light-emitting diode in the button and the
multi-functional PSM light on the instrument
panel go out.
The on-board computer shows a message.
