Climate control129
Individual menu items are marked by
turning the centre control and
selected by pressing it.
To exit a menu, turn the centre control until Return or Main appear and
select.
Air distribution Turn the centre control. The Air
distribut. menu is activated, showing
the possible air distribution settings:Top=to windscreen and front
door windows.Centre=to vehicle occupants.Bottom=to foot well.
The Air distribut. menu can also be
called up via the Climate menu.
Return to automatic air distribution:
Deactivate corresponding setting or
press button AUTO.
Cooling
In the Climate menu, select menu
item AC and activate or deactivate
cooling.
The air conditioning system cools and
dehumidifies (dries) when outside
temperature is above a specific level. Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel, Eco appears in the display.
Fan regulation in automatic
mode
Fan regulation in automatic mode can
be adapted.
Select menu item Automatic blower
from the Climate menu and select the
desired fan regulation.
Manual air recirculation mode The manual air recirculation mode is
operated with the 4 button.9Warning
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. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.

130Climate 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 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.
To open vent, turn the adjuster wheel
to B.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel to 7.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.

Climate control131Maintenance
Air intake
The air intakes in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.
Service For optimal cooling performance, it isrecommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
■ Functionality and pressure test■ Heating functionality
■ Leakage check
■ Check of drive belts
■ Cleaning of condenser and evaporator drainage
■ Performance check

higher fuel consumption and
CO 2 emission levels and a lower
maximum speed.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Do not mount towing equipment to
vehicles with Z 20 LEH engine.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case, use the coupling ball bar for towing. Always keep the
coupling ball bar in the vehicle.
Installation dimensions of factory-
fitted towing equipment 3 232.Driving characteristics and
towing tips Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the
coupling ball, is being used to reduce snaking movements.
For trailers with low driving stability
and trailers with a permitted gross
vehicle weight of more than 1300 kg
(Saloon) /1200 kg (Station wagon) a
speed of 80 km/h must not be
exceeded; the use of a stabiliser is
recommended.
If the trailer starts snaking, drive more
slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 225.

160Vehicle care
■ Open bonnet, close all doors andlock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Be aware that all systems
are non-operational, e.g. the anti-
theft alarm system.
Putting back into operation The following must be done if the
vehicle is put back into operation:
■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronics of the
power windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir.
■ Check the engine oil level.
■ Check the coolant level.
■ Fit the number plate if necessary.End-of-life vehicle
recovery
Information about end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our website. Only entrust this work to an
authorised recycling centre.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.

Vehicle care163
Coolant levelCaution
Too low a coolant level can causeengine damage.
When the cooling system is cold, the
coolant level should be just above the
KALT/COLD mark. Top up if the level
is low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
Top up with antifreeze. If no
antifreeze is available, use clean tap
water or distilled water. Install the cap
tightly. Have the antifreeze
concentration checked and have the
cause of the coolant loss remedied by a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of windscreen
washer fluid which contains
antifreeze.
Brakes A squealing noise indicates that the
brake lining is at its minimum
thickness. Continued driving is
possible but have the brake lining
replaced as soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.

Vehicle care193Wheel coversWheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.
Remove the wheel covers if tyre
chains are to be installed.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 10 mm to the tyre tread
and the inboard sides (including chain lock).
9 Warning
Damage may lead to tyre blowout.
Tyre chains are permitted on tyres of
size 185/65 R 15, 195/60 R 15,
195/65 R 15, 205/55 R 16 and
205/50 R17.
Tyre chains are not permitted on tyres of size 225/45 R 17, 225/40 R 18,
225/40 ZR18 and 235/35 R 19 2)
.
Saloon, Station wagon, Van: tyre chains are only approved on tyres of
size 215/45 R 17 if the vehicle was
equipped with 18-inch wheels in the
factory.
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is near the rim cannot be repaired with the tyre repair kit.2) Just permitted with limitation steering angle.
