Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 109, 3 154 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
If control indicator Z flashes, the
permitted emission limits may be
exceeded. Lift your foot off the
accelerator until Z stops flashing and
is steadily illuminated. Contact a
workshop immediately.

Starting off
When the engine is started, the
transmission is in automatic mode.
Depress the foot brake and move the selector lever towards + to engage
first gear. If R is selected,
reverse gear is engaged. The vehicle
starts to move when the foot brake is
released. To start off quickly, release
the foot brake and accelerate
immediately after engaging a gear.
In automatic mode the transmission
shifts to other gears automatically,
dependent on driving conditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display. To engage
first gear, depress foot brake and
move selector lever towards + or -.
Shift to a higher or lower gear by
moving selector lever to + or -. Gears
can be skipped by moving the
selector lever repeatedly at short
intervals.
Stopping the vehicle
In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped. In R, reverse gear remains engaged.
When stopping on gradients, engage parking brake or depress the foot
brake. To prevent overheating of the
clutch, an intermittent audiblewarning may sound as a signal to
depress the foot brake or apply the
parking brake.
Switch off engine if stopping for a lengthy period, e.g. in traffic jams.
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the foot brake has not
been depressed.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect,
select a lower gear in good time when
driving downhill.
Driving and operating99
Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.
Parking
Apply the parking brake. The most
recently engaged gear (see
transmission display) remains
engaged. With N, no gear is engaged.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
Manual mode
If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or too high an engine speed.If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.
Electronic driving
programmes
Winter mode V
Activate the Winter mode if you have
problems starting off on a slippery
road surface.

suitable gear.
Deactivation
The Winter mode is switched off by:
■ pressing the V button again,
■ turning off the ignition,
■ switching to manual mode.
In order to protect the transmission at extremely high clutch temperatures,
an intermittent audible warning may
sound. In such cases, depress the
foot brake, select "N" and apply the
parking brake to allow the clutch to
cool down.
100Driving and operating
Laden mode kg
It is possible to use the Laden mode
in both manual and automatic modes. In both cases, the gear shifting
patterns are adapted automatically
for carrying an increased payload.
Activation
Press the kg button. kg is shown in the
transmission display. The
transmission will then select
optimized gear shift patterns.
Deactivation
The Laden mode is switched off by:
■ pressing the kg button again,
■ turning off the ignition.
Kickdown If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear depending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault
In the event of a fault, W is shown in
the transmission display. Continued driving is possible provided the
vehicle is driven with care and
anticipation.
Have the cause of the fault remedied
by a workshop.Interruption of power
supply
The clutch is not disengaged if there is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 139.
If the cause of the fault is not a
discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the
drive wheels raised off the ground.
Towing the vehicle 3 141.
Driving and operating101Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
If control indicator R illuminates in
the instrument cluster while driving and the message BRAKING FAULT
appears in the Driver Information
Centre there is a fault in the braking
system. Seek the assistance of a
workshop immediately.Control indicator R 3 71.
Vehicle messages 3 75.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure as soon as a wheel shows a tendency
to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
Control indicator u 3 72.
Fault If control indicator u does not go out
a few seconds after the ignition is
switched on, or if it illuminates while driving, there is a fault in the ABS.
Control indicator A may alsoilluminate in the instrument cluster
together with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre. The brake
system remains operational but
without ABS regulation.9 Warning
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.
If control indicators u, A , R and
C illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT is shown in the
Driver Information Centre. Seek the
assistance of a workshop.
Have the cause of the fault remedied
by a workshop.

102Driving and operatingParking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.
Control indicator R 3 71.
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 is
automatically reduced when the
brake pedal is released.Ride control systems
Traction Control system
The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
ignition is switched on and control
indicator v extinguishes in the
instrument cluster.
When TC is active v flashes.
