Cooling
112Climate control9Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen might mist up from outside, when cold air is
directed to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate s.
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 heater.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 to
lack of air movement.
Set the direction of the air flow by
turning the adjuster wheel from right to left and raise or lower the horizontal slats.
116Driving and operating
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -25 °С for diesel engines and -30 °C
for petrol engines. Required is an
engine oil with the correct viscosity,
the correct fuel, performed services
and a sufficiently charged battery.
With temperatures below -30 °C the
automatic transmission need a
warming phase of approx. 5 minutes. The selector lever must be in position
P .
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.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 is released. Overrun cut-
off is deactivated if catalytic converter
temperature is high.
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 starts the engine
automatically as soon as the clutch is
depressed. A battery sensor ensures
that an Autostop is only performed if
the 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.Deactivation
Deactivate the stop-start system
manually by pressing the eco button.
The deactivation is indicated by the
LED in the button going off.
Autostop
If the vehicle is at a low speed or at a standstill, activate an Autostop as
follows:
■ Depress the clutch pedal
■ shift the selector lever to neutral
■ release the clutch pedal
The engine will be switched off while the ignition stays on.
118Driving and operating
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates.
Control indicator - 3 81.
Restart of the engine by the
stop-start system
The selector lever has to be in N to
enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system.
■ The stop-start system is manually deactivated
■ the bonnet is opened
■ the driver's seat belt is unfastened and the driver's door is opened
■ the engine temperature is too low
■ the battery is discharged
■ the brake vacuum is not sufficient
■ the vehicle starts to move
■ the defrosting function is activated■ the climate control system requests
an engine start
■ the air conditioning is manually switched on
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
Parking ■ Do not park the vehicle on an easily
ignitable surface. The high
temperature of the exhaust system
could ignite the surface.
■ Always apply parking brake without
pressing release button. Apply as firmly as possible on downhill or
uphill slopes. Depress the foot
brake at the same time to reduce
operating force.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.■ If the vehicle is on a level surface or
uphill slope, engage first gear or set the selector lever to P before
switching off the ignition. On an
uphill slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill slope, engage reverse gear or set theselector lever to P before switching
off the ignition. Turn the front
wheels towards the kerb.
■ Lock the vehicle and activate the anti-theft locking system and the
anti-theft alarm system.
Driving and operating119Engine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving. The filter
is cleaned by burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Fuel
consumption may be higher during
this period. The emission of smells
and smoke during this process is
normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If the filter requires cleaning and
previous driving conditions did not
enable automatic cleaning, control
indicator ! flashes. Continue driving,
keeping engine speed above
2000 rpm. Shift down if necessary.
Diesel particle filter cleaning is then
started.
Stopping the journey or switching off
the engine during cleaning is not
recommended.
Caution
If the cleaning process is
interrupted more than once, there
is a great risk of provoking severe
engine damage.
Cleaning takes place quickest at high
engine speeds and loads.
122Driving and operating
■The automatic neutral shift function
automatically shifts to idling when
the vehicle is stopped with a
forward gear engaged.
■ The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.
Winter programme T
Activate the Winter programme to
assist starting-off on a slippery road
surface.
Activation
Press the T button with P, R , N , D or
3 engaged. The vehicle starts off in
3rd gear.
Deactivation
The Winter programme is switched off by:
■ pressing the T button again,
■ manually selecting 2 or 1,
■ turning off the ignition,
■ or if the transmission oil temperature is too high.
KickdownIf the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear depending on engine speed.
Fault
In the event of a fault, A illuminates.
The transmission no longer shifts
automatically. Continued travel is
possible with manual shifting.
2nd gear is not available. Manual
shifting:1=1st gear2=3rd gear3, D=4th gear
Have the cause of the fault remedied
by a workshop.
Interruption of power
supply
In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position.
If the battery is discharged, start the
vehicle using jump leads 3 187.
124Driving and operatingCaution
It is not advisable to drive with thehand resting on the selector lever.
Manual transmission
automated
This 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.
Starting the engine
Depress the foot brake when starting
the engine. If the foot brake is not
depressed, j illuminates in the
instrument cluster, "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 starting. There may be a slight
delay.
