Parking9 Warning
■ Do not park the vehicle on an
easily ignitable surface. The
high temperature of the exhaust
system could ignite the surface.
■ Always apply the parking brake.
Activate the manual parking
brake without pressing the
release button. Apply as firmly
as possible on a downhill slope
or uphill slope. Depress foot
brake at the same time to
reduce operating force.
For vehicles with electric
parking brake, pull switch m for
approx. one second.
The electric parking brake is
applied when control indicator
m illuminates 3 112.
■ Switch off the engine. ■ If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector lever
to position P before removing
the ignition key. On an uphill
slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position P before removing the ignition
key. Turn the front wheels
towards the kerb.■ Close the windows.
■ Remove the ignition key. Turn the steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
■ Lock the vehicle.
■ Activate the anti-theft alarm system.
Notice
In the event of an accident with airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain
time.
Driving and operating167Selector leverP=park position, wheels are locked,engage only when the vehicle is
stationary and the parking brake

the vehicle is stationaryN=neutralD=automatic mode with all gears
The selector lever is locked in P and
can only be moved when the ignition is on and the brake pedal is applied.
Without brake pedal applied, the
control indicator j illuminates.
If the selector lever is not in P when
the ignition is switched off, the control
indicators j and P flash.
To engage P or R, press the release
button.
The engine can only be started with the lever in position P or N. When
position N is selected, press the brake
pedal or apply the parking brake
before starting.
Do not accelerate while engaging a
gear. Never depress the accelerator
pedal and brake pedal at the same
time.
When a gear is engaged, the vehicle
slowly begins to creep when the
brake is released.
Engine braking
To utilise the engine braking effect,
select a lower gear in good time when driving downhill, see manual mode.
Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between D and R in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
Apply the parking brake and engage P .
The ignition key can only be removed
when the selector lever is in position
P .
Driving and operating169Interruption of power
supply
In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position. The ignition key cannot be
removed from the ignition switch.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 259.
If the vehicle battery is not the cause
of the fault, release the selector lever.
1. Apply the parking brake.2. Release the selector lever trim from the centre console at the
front, fold it upwards and rotate it
to the left.
3. Insert a screwdriver into the opening as far as it will go and
move the selector lever out of P or
N . If P or N is engaged again, the
selector lever will be locked in
position again. Have the cause of
the power supply interruption
remedied by a workshop.
4. Mount the selector lever trim onto
the centre console and refit.
Manual transmission
To engage reverse, with the vehicle
stationary, depress clutch pedal,
press the release button on the
selector lever and engage the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
Driving and operating171
Fault9Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Manual parking brake9 Warning

Electric parking brake
Applying when vehicle is stationary
9 Warning
Pull switch m for approx.
one second, the electric parking
brake operates automatically with
172Driving and operatingadequate force. For maximum
force, e.g. parking with trailer or on
inclines, pull switch m twice.
The electric parking brake is
applied when control indicator m
illuminates 3 112.
The electric parking brake can always
be activated, even if the ignition is off.
Do not operate electric parking brake
system too often with engine not
running, as this will discharge the
vehicle battery.
Before leaving the vehicle, check the electric parking brake status. Control
indicator m 3 112.
Releasing
Switch on ignition. Keep brake pedal
depressed and then press switch m.
Drive away function
Depressing clutch pedal (manual
transmission) or engaging drive gear
(automatic transmission) and then
depressing the accelerator pedal
releases the electric parking brake
automatically. This is not possible
when the switch is pulled at the same
time.
This function also helps driving away
on inclines.
Aggressive drive-away may reduce
lifetime of wear parts.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electric
parking brake system will decelerate the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Fault
Failure mode of electric parking brake
is indicated by control indicator j and
by a code number or a vehicle
message which is displayed in the
Driver Information Centre (DIC).
Vehicle messages 3 123.Apply electric parking brake: pull and
hold switch m for more than
5 seconds. If control indicator m
illuminates, electric parking brake is
applied.
Release electric parking brake: press and hold switch m for more than
2 seconds. If control indicator m
extinguishes, electric parking brake is
released.
Control indicator m flashes: electric
parking brake is not fully applied or released. When continuously
flashing, release electric parking
brake and retry applying.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking is required. Maximum brake force isautomatically reduced when the
brake pedal is released.
