Vehicle care143General Information
Accessories and vehicle modifications
We recommend the use of 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
If the vehicle is to 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 the engine oil.
● Drain the washer fluid reservoir. ● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park vehicle in a dry, well ventilated place. Engage first or
reverse gear. Prevent the vehicle from rolling.
● Do not apply the parking brake.● Open the bonnet, close all doors and lock 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 When the vehicle is to be 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.
144Vehicle careEnd-of-life vehicle recoveryInformation 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.
9 Danger
The ignition system generates
extremely high voltages. Do not
touch.
The caps for topping up the engine oil, the coolant, the washer fluid and the
oil dipstick handle are yellow for ease
of identification.
Bonnet
Opening
Pull the release lever and return it to
its original position.
Vehicle care145
Move the safety catch (located
slightly right of centre) sideways to
the left vehicle side and open the
bonnet.
The bonnet is held open
automatically by a lifter.
If the bonnet is opened during an Autostop, the engine will be restarted automatically for safety reasons.
Stop-start system 3 117.
Closing
Lower the bonnet and allow it to fall
into the latch from a low height
(approx. 30 cm). Check that the
bonnet is engaged.
Caution
Do not press the bonnet into the
latch, to avoid dents.
Engine oil
Check the engine oil level manually
on a regular basis to prevent damage
to the engine.
Ensure that the correct specification
of oil is used. Recommended fluids
and lubricants 3 181.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 10 minutes.
Pull out the dipstick, wipe it clean, insert it to the stop on the handle, pull
out and read the engine oil level.
Caution
It is the owner's responsibility to
maintain the proper level of an
appropriate quality oil in the
engine.
When the engine oil level has
dropped to the MIN mark, top-up
engine oil.
Caution
Do not allow the engine oil level to drop below the minimum level!
146Vehicle care
We recommend the use of the same
grade of engine oil that was used at
the last change.
The engine oil level must not exceed
the maximum mark MAX on the
dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.
To prevent spillage when
replenishing the engine oil, we
recommend using a funnel to top-up the engine oil. Ensure funnel is
securely located onto the filler pipe.
After topping-up, put the funnel into a
plastic bag and stow it securely.
A stabilization of the engine oil
consumption will not take place until the vehicle has been driven several
thousand miles. Only then can the
actual degree of consumption be
established.
If consumption exceeds more than
0.5 litres every 600 miles after this
running-in period, consult a
workshop.
Capacities 3 195.
Fit the cap on straight and tighten it.Engine air filter
Engine air flow indicator
On certain models, an indicator is
located in the engine induction
system and indicates if the air-intake
to the engine is restricted.
Clear:No restrictionRed tell-tale:Restricted
If the red tell-tale is displayed when
the engine is running, consult a
workshop.
Vehicle care151
Drain filter of residual water at every
engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screw on the lower part of the filter by approx. one turn, to drain off the
water.
The filter is drained as soon as water-
free diesel fuel emerges. Retighten
the screw.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system bleeding
If the fuel tank has been run dry, it will be necessary to air vent or bleed the
diesel fuel system.
Refuel then proceed as follows:
With ignition key
● Switch on the ignition (key to position 2) for 5 seconds at a
time.
● Switch off ignition (key to position
1 ) for 3 seconds.
● Repeat this process multiple
times.
● Start the engine (key to position 3) then switch off (key to position
0 ).
Ignition switch positions 3 114.
With power button
● Insert the electronic key in the card reader.
● Press START/STOP without
pressing any of the pedals.
● Wait a few minutes before starting engine.
Power button 3 114.

3.Place lifting pad spigot of the jack
under the jacking hole located
nearest the wheel concerned.
Ensure the jack is positioned
correctly. The jack base must be
on the ground directly below the
jacking hole in a manner that
prevents it from slipping.
4. Install wrench onto the jack and raise the vehicle by turning the
wrench until the wheel is clear of
the ground.
5. Unscrew wheel bolts completely by turning anticlockwise and wipe
clean with a cloth.
Put wheel bolts somewhere
where the threads will not be
soiled.
6. Change the wheel. Spare wheel 3 172.
7. Screw in the wheel bolts.
8. Lower the vehicle and remove jack.
9. Tighten each of the wheel bolts in
a crosswise sequence using the
wheel wrench. Ensure the wrench locates securely. The wrench
should turn clockwise to tighten
the bolts. Invert the wrench if
necessary.
Tightening torque is 160 Nm.
10. Replace the wheel cover, ensuring that the valve hole in thewheel cover is aligned with the
tyre valve before installing.
Notice
If applicable, fit anti-theft bolts
nearest the tyre valve (otherwise it
may not be possible to refit the wheel
cover).11. Stow the replaced wheel 3 172
and the vehicle tools 3 162.
12. Have the new wheel balanced on the vehicle.
Check the tyre pressure of the
installed tyre 3 196.
Check the wheel bolt torque.
Have the defective tyre renewed or
repaired as soon as possible.
Spare wheel
Some vehicles are equipped with a tyre repair kit instead of a spare wheel
3 168.
If mounting a spare wheel which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
178Vehicle careMatt filmed body parts or decor tapesmust not be polished, to avoid
gleaming. Do not use hot wax
programmes in automatic car washes if the vehicle is equipped with theseparts.
Matt painted decor parts, e.g. mirror
housing cover, must not be polished.
Otherwise these parts would become agleam or the colour would be
dissolved.
Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Remove dirt residues from smearing wiper blades by using a soft cloth and window cleaner. Also make sure toremove any residues such as wax,
insect residues and similar from the
window.
Ice residues, pollution and continuous
wiping on dry windows will damage or
even destroy the wiper blades.
Wheels and tyres
Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damageRectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
Underbody Some areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Towing equipment Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean any leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.
