Low fluid level in engine cooling
system. Check coolant level 3 154.
Drain diesel fuel filter If there is water in the diesel fuel filter,
the message InSP4 appears in the
instrument panel. Consult a
workshop.
Lighting
Important exterior lights, including
cables and fuses, are monitored. In
trailer mode, trailer lighting is also
monitored. Trailers with LED lighting
must have an adapter that enables
light monitoring as with conventional
bulbs.
The failed lighting will be indicated in
the information display or the
message InSP2 will appear in the
instrument panel display.

monitoring system, if there is low tyre pressure, information which tyre to
check appears on the display.

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.
Air vents without adjuster wheel

Accessories and vehicle
modifications
We recommend using genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
Following must be done if the vehicle
should be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve rubber seals.
■ Fill up fuel tank completely.
■ Change engine oil.
■ Drain washer fluid reservoir.
■ Check coolant antifreeze.
■ Adjust tyre pressure to the value specified for full load.
■ Park vehicle in dry, well ventilated place. Engage first or reverse gear
or set selector lever to P. Prevent
the vehicle from rolling.
■ Do not apply parking brake.
Page 154 of 217
152Vehicle care
■ Open bonnet, close all doors andlock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are not functional, e.g. anti-theft alarm
system.
Putting back into operation Following must be done if the vehicle
is putting 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 on 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.
Page 155 of 217
Vehicle care1539Danger
The ignition system and Xenon
headlights use extremely high
voltage. Do not touch.
The caps for topping up the engine oil, the coolant, the washing fluid and theoil dipstick handle are yellow for ease
of identification.
Bonnet
Opening
Pull the release lever and return it to
its original position.
Lift the safety catch upwards and
open the bonnet.
Air intake 3 123.
Secure the bonnet support.
Closing Before closing the bonnet, press the
support into the holder.
Lower the bonnet and allow it to drop into the catch. Check that the bonnet
is engaged.
Engine oil Check the engine oil level manuallyon a regular basis to prevent damage
to the engine. Ensure that the correct specification of oil is used.
Recommended fluids and lubricants
3 192.
Page 156 of 217
154Vehicle care
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 minutes.
Pull out the dipstick, wipe it clean, insert it to the stop on the handle, pull
out and read the engine oil level.
Insert dipstick to the stop on the
handle and make half a turn.
Different dipsticks are used
depending on engine variant.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.
We recommend to use the same
engine oil that is filled in.
The engine oil level must not exceed the MAX mark on the dipstick.Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 205.
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -28 °C.
Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
Page 157 of 217

Vehicle care155
If 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. For the correct mixing ratio refer to the washer fluid container.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
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.
Brake fluid
9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.
