122Climate control
Air conditioning with the engine
not running When ignition is off, the residual heat
or cooling in the system can be used
for climate control in passenger
compartment.
Press the AUTO button with the
ignition off. Residual air conditioning
on will appear briefly in the display.
Residual climate control can only
operate for a limited period of time. To
cancel, press the AUTO button.
Auxiliary heater
Air heater Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Coolant heater Diesel-engined vehicles have a fuel-
powered auxiliary coolant heater
which warms up the engine coolant
when the engine is running.Air vents
Adjustable air vents
At least one air vent must be open
while cooling is on in order to prevent the evaporator from icing up due tolack of air movement.
Air vents with adjuster wheel
To open or close the vent, turn the
adjuster wheel.
Direct the flow of air by tilting and
swivelling the slats.

128Driving and operating
The control indicator ! extinguishes
as soon as the self-cleaning
operation is complete.
If A illuminates additionally, cleaning
is not possible, seek the assistance of
a workshop.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 144, 3 200 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.
Automatic transmission
The automatic transmission makes
automatic shifting possible
(automatic mode) and the version
with ActiveSelect also makes manual
shifting possible (manual mode).
Transmission display
The mode or selected gear is shown
in the transmission display.

Driving and operating129
On vehicles with Open&Start system,
P flashes in the transmission display
when the ignition is switched off if P is
not engaged or the parking brake is
not applied.
If Sport mode is activated, 1 is
illuminated.
If the Winter programme is activated,
T is illuminated.
Selector leverP=park position, front wheels
locked, engage only when the
vehicle is stationary and the
parking brake is appliedR=reverse gear, engage only
when vehicle is stationaryN=neutralD=automatic mode with all gears
The selector lever can only be moved out of P or N when the ignition is on
and the foot brake is depressed
(Selector lever lock).
When the selector lever is in N, the
selector lever lock is activated after a
delay and only if the vehicle is
stationary.
When the selector lever is in the P or
N position, control indicator j in the
gear indicator strip illuminates red
when the selector lever is locked. If
the selector lever is not in the P
position when the ignition is switched
off, control indicator j and P in the
gear indicator strip flash.
To engage P or R, press the release
button on selector lever.
When position N is selected, press
foot brake or engage parking brake
before starting.

134Driving and operatingManual transmission
automated
The Easytronic transmission permits manual (manual mode) or automatic
gear shifting (automatic mode), both
with automatic clutch control.
Transmission display
Shows the mode and current gear.
The display flashes for a few seconds
when A, M or R is selected with the
engine running and the foot brake not
activated.
If the Winter programme is activated,
T is illuminated.
Starting the engine
Depress the foot brake when starting
the engine. If the foot brake is not
depressed, j illuminates in the
instrument, "N" flashes in the
transmission display and the engine
cannot be started.
Starting is not possible if all brake
lights fail.
When the foot brake is depressed, the
transmission automatically shifts to
N upon start. There may be a slight
delay.Selector lever
Always move the selector lever in the
appropriate direction as far as it will
go. Upon release, it automatically
returns to the centre position.
N=Neutral.A=Switch between automatic and
manual mode. The
transmission display shows A

Driving and operating135
Starting off
Depress the foot brake and move the selector lever to A, + or -. The
transmission is in automatic mode
and first gear is engaged. If R is
selected, reverse gear is engaged.
The vehicle starts to move when the
brake is released.
To start off without depressing the
foot brake, accelerate immediately
after engaging a gear.
If neither the accelerator nor the
brake pedal are depressed, no gear
is engaged and A or R flashes for a
brief time in the display.
Stopping the vehicle
In A, first gear is engaged and the
clutch is released when the vehicle is stopped. In R, reverse gear remains
engaged.
Engine braking Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairlyhigh 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 or snow. Move the selector
lever between R and A in a repeat
pattern. 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.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increases engine speed to quickly bring the
catalytic converter to the required
temperature.

Driving and operating137
If F appears in the transmission
display, continued driving is not
possible.
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 battery is discharged, start the
vehicle using jump leads 3 184.
If the cause of the fault is not a
discharged battery, seek the
assistance of a workshop.
If the vehicle must be moved out of the flow of traffic, disengage the
clutch as follows:
1. Apply parking brake and switch off
ignition.
2. Open the bonnet 3 153.
3. Clean the transmission around the cap so that no dirt can get intothe opening when the cap is
removed.
4. Rotate cap to slacken and remove
by lifting upwards.
5. Using a flat-head screwdriver, turn the adjusting screw under the
cap clockwise until clear
resistance can be felt. The clutch
has now been disengaged.
6. Refit cleaned cap. The cap must be in full contact with the housing.Caution
Do not turn beyond the resistancesince this could damage the
transmission.
Caution
Towing the vehicle and starting
the engine is not permitted when
the clutch has been disengaged in this way, although the vehicle can
be moved a short distance.
Seek the immediate assistance of a
workshop.
