96Climate controlAuxiliary heater
Air heater Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.Air vents
Adjustable air vents Centre air vents in the instrument
panel
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, swivel the slats
inwards.
Outer air vents in the instrument
panel
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, swivel the slats
outwards.
At least two air vents must be open
while cooling is on.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Driving and operating103Starting the vehicle at lowtemperatures
Starting 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 vehicle battery.
With temperatures below -30 °C the
automatic transmission requires 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 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.
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.
The system is ready to operate when
the LED in the button D is not
illuminated. To activate the system
when the system is deactivated,
press D.
If the stop-start system is temporarily
not available and the button D is
pressed, the LED in the button
flashes.
Deactivation
Deactivate the stop-start system
manually by pressing D. The
deactivation is indicated when the
LED in the button illuminates.
Driving and operating105Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the driver
Vehicles with manual transmission
Depress the clutch pedal without depressing the brake pedal to restart
the engine.
Vehicles with automatic transmission
The engine is restarted in the
following cases:
● brake pedal released while the selector lever in position D or M
● brake pedal released or selector lever in position N when selector
lever is moved to position D or
M
● selector lever moved to position RRestart of the engine by the stop-
start system
The selector lever must be in neutral 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:
● stop-start system manually deactivated
● driver's seat belt unfastened and driver's door opened
● engine temperature too low
● charging level of vehicle battery below a defined level
● brake vacuum not sufficient
● vehicle driven at least at walking speed
● climate control system requests engine start
● air conditioning manually switched on
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake.
● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position P. 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 the selector lever to position
P . Turn the front wheels
towards the kerb.
● Close the windows.
● Switch off the engine.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with power
108Driving and operatingCaution
Avoid contact of the paintwork withAdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
Note
Frozen and again liquefied AdBlue is usable without quality loss.
The typical AdBlue consumption is
approx. 0.85 l per 1000 km, but can
also be higher depending on driving
behaviour (e.g. high load or towing).
Level warnings
Depending on the calculated range of AdBlue, different messages are
displayed in the Driver Information
Centre. The messages and the
restrictions are a legal requirement.
1. The first warning level is entered when the estimated AdBlue range
is between 2400 km and 800 km.
When switching on the ignition,
this warning will show up once
briefly with the calculated range.
Additionally, control indicator u
will illuminate and a chime will
sound. Driving is possible without
any restrictions.
2. The next warning level is entered when the estimated AdBlue rangeis below 800 km. The message
with the current range will always
be displayed when ignition is
switched on. Additionally, control
indicator u will flash and a chime
will sound. Refill AdBlue before
entering the next warning level.
3. The next warning level is entered with a range below 100 km. The
message with the current range
will always be displayed when
ignition is switched on.
Additionally, control indicator u
will flash and a chime will sound.
Refill AdBlue as soon as possible
before the AdBlue tank iscompletely empty. Otherwise, a
restart of the engine will not be
possible.
4. The last warning level is entered when the AdBlue tank is empty.
Restart of the engine is not
possible.
A message appears in the Driver
Information Centre. Additionally,
control indicator u will flash and
a chime will sound.
Refill the tank to a level of at least
5 l of AdBlue, otherwise restarting
of the engine is not possible.
High emission warnings In the event of a fault with the
emissions control system, different messages are displayed in the Driver Information Centre.
The messages and the restrictions
are a legal requirement. The warning
messages are accompanied by the
control indicators u, C and W.
Additionally, a chime will sound.
Follow the instructions of the warning
messages. If starting is prevented,
seek the assistance of a workshop.
Driving and operating157application of the special servicingconditions referred to as "Arduous
conditions".
For more information, contact a
dealer or a qualified workshop.Caution
The use of any other type of (bio)
fuel (vegetable or animal oils, pure
or diluted, domestic fuel etc.) is
strictly prohibited (risk of damage
to the engine and fuel system).
Note
The only Diesel additives authorised for use are those that meet the
B715000 standard.
Low temperature operation
At temperatures below 0 °C, some
diesel products with biodiesel blends may clog, freeze or gel, which mayaffect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0 °C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20 °C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage on the fuel
injection system.
Refuelling9 Danger
Before refuelling, switch off
ignition and any external heaters
with combustion chambers.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at right rear
side of vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked. Release the
fuel filler flap by pushing the flap.
