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
3 178.
Low engine oil level control indicator
S 3 89.
The maximum engine oil
consumption is 0.6 litres per
1000 km.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least five 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.
Note
Different dipsticks may be used
depending on engine variant.When the engine oil level has
dropped to the MIN mark, top up
engine oil.
Note
The engine in your vehicle may differ from the illustrations shown.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.

Vehicle care145Capacities 3 190.
Fit the cap on straight and tighten it.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
cold regions with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.Caution
Only use approved antifreeze.
Coolant and antifreeze 3 178.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be between the
MIN and MAX 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.
To top up, use a 1:1 mixture of
approved coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Coolant and antifreeze 3 178.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not
work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.

Vehicle care149Wiper blade on tailgate
Lift wiper arm, press retaining clips to
detach wiper blade.
Attach the wiper blade to the wiper
arm and push until it engages.
Lower wiper arm carefully.
Bulb replacement
Switch off the ignition and switch off
the relevant switch or close the doors.
Only hold a new bulb at the base! Do not touch the bulb glass with bare
hands.
Use only the same bulb type for
replacement.
Replace headlight bulbs from within
the engine compartment.
Bulb check
After a bulb replacement, switch on
the ignition, operate and check the
lights.Halogen headlights
Headlights have separate systems for low beam/sidelight 1 (outer bulb),
high beam/daytime running light 2
(inner bulb).
To access bulbs, pull off protective
covers.
Low beam 1. Remove protective cover.
2. Detach connector from bulb.
3. Disengage wire clip and remove bulb from reflector.

Vehicle care161Tyre pressures differ depending on
various options. For the correct tyre pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 183.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 191.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct adjustment of tyre pressures.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
10 kPa (0.1 bar) for a 10 °C
temperature increase. This must be
considered when warm tyres are
checked.
Tyre pressure monitoring
system
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
The tyre pressure monitoring system sensors monitor the air pressure in
the tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Tyre pressure chart 3 191.

Vehicle care165
5. Screw the flexible filler hose ontothe tyre valve.
6. The switch on the compressor must be set to J.
7. Connect the compressor plug to the power outlet or cigarette
lighter socket.
To avoid discharging the vehicle
battery, we recommend running
the engine.8. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
9. All of the sealant is pumped into the tyre. Then the tyre is inflated.
Tyre pressure 3 191. When the
correct pressure is obtained,
switch off the compressor.
10. If a pressure of 1.5 bar is not obtained within five minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for five minutes. If a pressure of
1.8 bar is still not obtained within
five minutes, the tyre is too badly
damaged. Seek the assistance of
a workshop.
Do not run the compressor longer
than 20 minutes.
11. Detach the tyre repair kit.
12. Remove any excess sealant using a cloth.
13. Take the label indicating maximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
14. Continue driving immediately so that sealant is evenly distributedin the tyre. After driving approx.
10 km (but no more than
ten minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.

Vehicle care175For 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.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Remove dirt residues from smearing
wiper blades by using a soft cloth and
window cleaner. Also make sure to
remove 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.
Glass panel
Never clean with solvents or abrasive agents, fuels, aggressive media (e.g.
paint cleaner, acetone-containing
solutions etc.), acidic or highly
alkaline media or abrasive pads. Do
not apply wax or polishing agents to
the glass panel.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 damage Rectify 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.
Natural gas system
Do not direct the steam jet or high-
pressure jet towards natural gas
system components. It is particularly
important to protect the natural gas tank and the pressure valves on the
vehicle underbody and the bulkhead
in the engine compartment.
These components must not be
treated using chemical cleaners or
preservatives.
Have components of the natural gas
system cleaned by a workshop
authorised to carry out maintenance
of natural gas vehicles.
Towing equipment
Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
