Examples of PSM control operations
– If the front wheels of the vehicle drift on a
bend, the rear wheel on the inside of the bend
is braked and the engine power is reduced if
necessary.
– If the rear of the vehicle swings out on a bend,
the front wheel on the outside of the bend is
braked.
Additional functions for vehicles with
four-wheel drive
– Pre-filling the brake system:
If you suddenly and quickly take your foot off
the accelerator pedal, the brake system gets
prepared for possible emergency braking. The
brake system is pre-filled which lightly presses
the brake pads on the brake discs.
Brake boost:
If emergency braking does not have sufficient
pedal pressure, the brake boost produces
the brake pressure necessary for maximum decel-
eration on all 4 wheels.The 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 PSMfPress PSM OFF button.
PSM is switched off after a short delay.
The light-emitting diode in the button is illumi-
nated.
When the PSM is switched off, the multifunc-
tional PSM light on the instrument panel is lit
and a message is shown by the on-board
computer. An acoustic signal also sounds.
Vehicles with four-wheel drive
When PSM is switched off, the additional braking
functions are deactivated. The automatic reactiva-
tion in emergency situations is coupled to the PSM
control in emergency situations.

74
Controls, Instruments The following functions stabilize the vehicle in
emergency situations, even with PSM switched
off:
– When PSM is off, the vehicle is stabilized 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 stabilized 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 onfPress PSM OFF button.
PSM is switched on after a short delay.
The light-emitting diode in the button and the
multifunctional PSM light go out.
The on-board computer shows a message.Sport modeA sportier car set-up is obtained when Sport mode
is switched on. PSM interventions are later than in
Normal mode; the vehicle can be manoeuvred
with greater agility at its performance limits,
without the need to dispense with the assistance
of PSM in emergency situations. This helps to
achieve optimal lap times, particularly on race
circuits and a dry road surface.– The multifunctional light on the instrument
panel lights up for a lamp check when the
ignition is switched on.
– The light indicates a control operation by
flashing, including when PSM is switched off
(brake control in the event of one-sided wheel
spin).
– In conjunction with a message on the on-board
computer, the light indicates that PSM is
switched off.
An acoustic signal also sounds.
– Faults are displayed by the light in conjunction
with a message on the on-board computer.
PSM is out of order.

TOWING” on Page 281.Checks on test standsBrake tests
Brake tests must be performed only on plate-type
test stands or roller test stands.
The following limit values must not be exceeded
on roller test stands:
– Testing speed 5 mph (8 km/h)
– Test duration 20 seconds
Handbrake tests
Handbrake tests on the roller test stand must be
performed only with the ignition switched off.

PASM makes two running-gear setups available to
the driver: “Normal” and “Sport”.
The selection is made via a button on the center
console.
In Normal mode the running gear is in a sporty and
comfortable setup.
Sport mode offers a markedly sporty shock
absorber tuning (e.g. for driving on the race
circuit).
The variable suspension system selects the appro-
priate damping level for each wheel according to
the situation and conditions of driving.
Example:
If the vehicle is driven in a markedly sporty manner
in Normal mode, PASM automatically adapts the
shock-absorber behavior to the driving situation in
this case as well.
Switching on PASM Sport modefPress PASM button in the center console.
When PASM Sport mode is switched on, the
light-emitting diode in the button is illuminated
and a message is shown by the on-board
computer.
Switching off PASM Sport modefPress PASM button in the center console.
The light-emitting diode in the button goes out
and the on-board computer displays a
message.
After the ignition is switched off, PASM is automat-
ically reset to Normal mode.

light.
Otherwise the mirrors may accidentally swivel
into the anti-dazzle position.

The interior and footwell lights are switched
on when a door is unlocked or opened or when
the ignition key is withdrawn from the ignition
lock.
The lights are switched off with a delay of
approx. 2 minutes after the doors are closed.
The light goes out immediately as soon as the
ignition is switched on or the vehicle is locked.
Orientation lightA light-emitting diode at the bottom of the interior
mirror improves orientation in the passenger com-
partment when it is dark.
Note on operation
On vehicles with the Sport Chrono package, the
brightness of the orientation light can be changed
in PCM.
