Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam.It restarts the engine automatically as
soon as the clutch pedal is depressed (manual transmission) or the brake
pedal is released (manual
transmission automated).
A vehicle battery sensor ensures that
an Autostop is only performed if the vehicle battery is sufficiently charged
for a restart.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
If the below conditions are not
fulfilled, an Autostop is prohibited and

appropriate direction as far as it will
go. Upon release, it automatically
returns to the centre position.N:neutralA/M:switch between automatic and manual mode
The transmission display
shows "A" when in automatic
mode.R:reverse gear
Engage only when vehicle is
stationary. The transmission
display shows "R" when
reverse gear is engaged.+:shift to a higher gear.-:shift to a lower gear.
Starting off
When the engine is started, the
transmission is in automatic mode. Depress the brake pedal 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 brake pedal is released. To
start off quickly, release the brake pedal 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 brake
pedal 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 brake
pedal. To prevent overheating of the
clutch, an intermittent audible

156Driving and operatingwarning may sound as a signal to
depress the brake pedal 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 brake pedal 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.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.
If the ignition is not switched off, or the
parking brake has not been applied, a
warning chime will sound upon
opening the driver's door.
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, theshift 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.

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, control indicator 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.

Driving and operating163Limited-slip rear axle
Rear-wheel drive vehicles may be
equipped with an automatic locking
rear differential which automatically
controls the torque transmitted to
each rear wheel, enhancing traction
in the event of soft ground, mud or
snow-covered road surfaces.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
When vehicle speed reaches
30 km/h, or once the rear wheels
return to surfaces with normal grip,
e.g. paved roads, the system
automatically deactivates,
sometimes accompanied by a noise
(with no consequence to vehicle
behaviour).
The system can also be deactivated
manually once normal grip conditions have resumed by briefly releasing the
accelerator.
Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of 30 km/h and
above. Deviations from the stored
speeds may occur when driving uphill or downhill. The stored speed will
flash in the Driver Information Centre
3 106.
For safety reasons the cruise control
cannot be activated until the brake
pedal has been operated once.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
With manual transmission
