red.
It illuminates when the ignition is switched
on and goes out shortly after the engine
starts.
Flashes during or after engine start
Battery voltage too lo w. Have electrical
system tested by a workshop.
Illuminates when the engine is runningStop and switch engine off. Battery will not
be charged. Engine cooling may be
interrupted. Effect of brake servo unit may
stop in vehicles with diesel engines.
Contact a workshop for assistance. p
Electro-hydraulic power assisted steering
Control indicator lights up yellow.
Fault in electro-hydr aulic power assisted
steering system. The power assisted
steering may have failed. The vehicle can
be steered but considerably more force is
required. Contact a workshop for
assistance.

The control indicator flashes if a turn signal
or the hazard warning flashers are
activated.
Rapid flashes: A turn signal lamp or the
related fuse has failed, failure of turn signal
lamp on the trailer 3.

Driving and operation
If the vehicle is in automatic mode, on
movement of the selector lever to
+ or
- the
manual transmission automated shifts to
manual mode and changes up or down.
The gear currently engaged appears on
the transmission display.
Move selector lever toward R
Reverse gear. Engage only when vehicle is
stationary.
Depress the foot brake, release the hand
brake and move the selector lever to R.
Reverse gear is engaged. "R" appears in
the transmission display.
The vehicle begins to "creep" when the foot
brake is released.
It is also possible to start off in reverse
without depressing the foot brake if the
accelerator pedal is operated directly after
moving the selector lever. If there is no
acceleration or the foot brake is not
depressed, no gear is engaged and "R"
flashes. After a few seconds, the display
resumes showing "N". Start off by
repeating the previously described
procedure. Stopping the vehicle
In Automatic or Manual mode, when the
vehicle has stopped first gear (with Winter
mode engaged, second gear) is engaged
automatically and the clutch released. In
R
reverse remains engaged.
A warning buzzer sounds when the driver’s
door is opened if the engine is running, a
gear is engaged and the foot brake is not
depressed. The vehicle creeps if the hand
brake is not engaged. Move the selector
lever to N and apply the hand brake.
When stopping on gradients, engage the
hand brake or depress the brake pedal. To
prevent overheating of the clutch, do not
increase engine speed to ensure smooth
idling when in gear.
To prevent damage to the automated
manual transmission, the clutch is closed
automatically at high clutch temperatures.
Switch off engine if stopping for a lengthy
period, e.g. in traffic jams or at level
crossings. Electronically controlled driving
programmes
z
Following a cold start, the operating
temperature program automatically
increases the engine revolutions to bring
the catalytic converter to the required
temperature.
z The adaptive program automatically
selects the gear according to the driving
conditions, e.g. increased load and
gradients.

Driving and operation
Engine braking
In order to utilise the engine braking
effect when driving downhill, select drive
range 3,2 or, if necessary, 1 in good time.
Gear 1 has the greatest braking effect. If
gear 1 is selected at too great a speed
the transmission remains in 2nd until the
shifting point for 1st gear is achieved by
braking, for example.
"Rocking the car"
If it becomes necessary to rock the vehicle
to free it from sand, mud, snow or a hole,
move the selector lever from D to R
repeatedly. Do not race the engine and
avoid sudden acceleration.
Picture no: 18230s.tif
Manoeuvring the vehicle
To manoeuvre the vehicle back and forth
during attempts to park or in garage
entrances, the vehicle’s creeping
movement can be utilis ed by releasing the
brake pedal.
Never actuate accelerator and brake
pedals simultaneously. Stopping the vehicle
The selector lever can be left in the chosen
gear with the engine running.
When stopping on gr
adients engage hand
brake or depress brake pedal. To prevent
overheating of the transmission, do not
increase engine revolutions to ensure
smooth idling while standing if a gear has
been selected.
Switch off engine if stopping for a lengthy
period, e.g. in traffic jams or at level
crossings.
Before leaving the car, apply the hand
brake first, then select P. Remove the
ignition key. Lock the vehicle. Otherwise
the battery may become discharged if the
vehicle is parked for long periods.
The ignition key can only be removed when
the selector lever is in position P.

Catalytic converter, exhaust
gassesCatalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gas, such as carbon monoxide
(CO), hydrocarbons, CH) and nitrous
oxide (NO
x).
Fuel grades other than those listed on
pages 153, 252 (e. g. LRP = Lead
Replacement Petrol or leaded fuel) could
damage the catalytic converter or
electronic components. z
In the event of misfiring, uneven engine
running, a clear 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.
This does not apply when the Electronic
Stability Program (ESP®
Plus
3) kicks in
3 151.
z If unburnt fuel enters the catalytic
converter of a petrol engine, this may
result in overheating and irreparable
damage to the catalytic converter.
You should therefore avoid
unnecessarily long use of the starter
when starting off, running the tank dry
and starting the engine by pushing or
towing.
Picture no: 18182s.tif
Controlling exhaust emission
Design measures, primarily in the fuel
injection system and ignition system zones
in combination with the catalytic converter,
the amount of hazardous substances in the
exhaust emissions, such as carbon
monoxide (CO), hydrocarbons (CH) and
nitrogen oxides (NO
x), are reduced to a
minimum.
Caution
Damage to the catalytic converter or the
vehicle may result if the following points
are not observed.
