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.

surface.
To activate Press the T button with P , R , N , D or 3
engaged. The vehicle starts off in 3rd gear.
To deactivate The Winter programme is switched off by:
z pressing the T button again,
z manually selecting 2 or 1 ,
z turning off the ignition,
z or if the transmission oil temperature is
too high.

Kickdown
If the accelerator pedal is pressed past the
pressure point, the transmission shifts to a
lower gear depending on engine speed.

150 Driving and operationSave energy – more kilometres
Please observe the running-in hints on the
previous page and the tips for saving
energy on the following pages.
Good, technically correct and economical
driving ensures maximum durability and
performance for your vehicle.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, e.g. when the vehicle is
driven with a gear engaged but no throttle
application. Overrun cut-off is deactivated
if catalytic converter temperature is high.
Vehicles with turbocharged engine Flow-generated noises may be audible if
the accelerator is released quickly on
account of air flow in the turbocharger.
Engine speed
Drive in a low engine speed range for each
gear as much as possible. Warming up
After a cold start, the automatic
transmission
3 or manual transmission
automated 3 in automatic mode shifts into
higher gears at higher rpm. This allows the
catalytic converter to quickly reach the
temperature required for optimum pollutant
reduction.
Correct gear selection
Do not race your engine whilst in neutral or
with a low gear selected. Driving too fast in
individual gears as well as stop-and-go
traffic increases engine wear and fuel
consumption.
Change down
When decreasing speed, shift down into
the next lowest gear. Do not slip the clutch
with a high-revving engine. This is
especially important when hill climbing. Cooling fan
The cooling fan is controlled via a
thermoswitch and therefore only runs if
necessary.
The cooling fan automatically switches on
when the diesel particle filter is being
cleaned
3 depending on the engine.
Pedals
Do not place any objects in the foot well
which could slip under the pedals and
inhibit the pedal travel.
To ensure the pedal travel is uninhibited,
there must be no mats in the area of the
pedals.
Battery care
When driving slowly or when the vehicle is
stationary, e.g. in slow urban traffic, stop-
and-go traffic or traffic jams, turn off all
unnecessary electrical loads where
possible (e.g. heated rear window, heated
front seats, etc.).
Declutch when starting in order to relieve
the strain on the starter and the battery.

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.

system. The permissible emission limits
may be exceeded. Contact a workshop for
assistance immediately.

Control indicator
A

Illuminates for a few seconds after the
ignition is switched on.
If it illuminates when the engine is running,
there is a fault in engine or transmission
electronics. The electr onic system switches
to an emergency runni ng programme. Fuel
consumption may be increased and the
driveability of the vehicle may be impaired.
In some cases the fault can be remedied by
switching the engine off and starting it
again. If the control indicator continues to
illuminate whilst the en gine is running,
contact a workshop for assistance in
remedying the cause of the fault. If it illuminates briefly, but does not recur, it
is of no significance.
If
A lights up, this could mean that there
is water in the diesel fuel filter 3. A
message appears at the same time on the
service display 391. Have the fuel filter
checked for possible water contamination
by a workshop.
If it flashes after the ignition is switched on,
there is a fault in the immobiliser system.
The engine cannot be started 327.
