Vehicle care225Wheel covers
Wheel 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.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Vehicles with steel wheels: When
using locking wheel nuts, do not
attach wheel covers.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 9 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 215/70R16, 215/65 R17,
225/55 R18 and 205/55 R19.
Temporary spare wheel
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 at tyre's sidewall cannot be repaired with the tyre repair kit.9 Warning
Do not drive faster than 80 km/h.
Do not use for a lengthy period.
Steering and handling may be
affected.
In the case of a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.

Vehicle care229● Never crawl under a jacked-upvehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
Tightening torques
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
100 Nm.
Tightening torque for steel wheels is 115 Nm.
Just use the correct wheel bolts for the respective wheels.
Jacking positions
The jacking positions shown refer to
the use of lifting arms and accessory
jacks used for changing winter /
summer tyres.
Rear arm position of the lifting
platform centrically under the relevant vehicle jacking point.
Front arm position of the lifting
platform centrically under the relevant vehicle jacking point.
Spare wheel The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the other
mounted wheels and country
regulations. In this case a permissible maximum speed applies, even
though no label at the spare wheel
indicates this.

Vehicle care231● Before screwing in the wheelbolts, clean them.9Warning
Do not grease the thread of the
wheel bolt.
9 Warning
Ensure to use always the correct
wheel bolts if changing the
wheels. When installing the spare
wheel, the bolts for alloy wheels can also be used.
● Note that the spare wheel is secured by the conical contact ofeach bolt if the wheel bolts for the
alloy wheels are used. In this
case, the washers do not come
into contact with the spare wheel.
1. Disengage wheel bolt caps with the wheel bolt cover remover.
Vehicle tools 3 220.
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with the wheel bolt cover remover.
2. Fold out the wheel wrench and install ensuring that it locates
securely and loosen each wheel
nut by half a turn.
The wheels might be protected by
locking wheel nuts. To loosen
these specific nuts first attach the
adapter onto the head of the nut
before installing the wheel
wrench. The adapter is located in
the tool box 3 220.
3. Ensure the jack is correctly
positioned under the relevant
vehicle jacking point.

Vehicle care233
1.Remove centre cap with the brand
emblem by pushing from the
inside.
2. Position the wheel outside down in the wheel well.
3. Secure the defective wheel with the wing nut.
4. Depending on the tyre size, the floor cover can be placed on the
projecting wheel.
Jump starting
Do not start with quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already freeze at a temperature
of 0 °C. Defrost the frozen battery before connecting jump leads.
● Wear eye protection and protective clothing when
handling a battery.
● Use a booster battery with the same voltage (12 V). Its capacity
(Ah) must not be much less than
that of the discharged vehicle battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
(25 mm 2
for
diesel engines).
● Do not disconnect the discharged
vehicle battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● Do not lean over the vehicle battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.

242Service and maintenanceConfirmations
Confirmation of service is recorded in the Service and warranty booklet.
The date and mileage is completed
with the stamp and signature of the
servicing workshop.
Make sure that the Service and
warranty booklet is completed
correctly as continuous proof of
service is essential if any warranty or goodwill claims are to be met, and is
also a benefit when selling the
vehicle.Recommended fluids,
lubricants and parts
Recommended fluids andlubricants
Only use products that meet the
recommended specifications.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for
petrol and diesel engines. If it is
unavailable, engine oils of other listed qualities must be used.
Recommendations for petrol engines
are also valid for Compressed Natural
Gas (CNG), Liquified Petroleum Gas
(LPG) and Ethanol (E85) fuelled
engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 246.
Topping up engine oilCaution
In case of any spilled oil, wipe it up and dispose it properly.
Engine oils of different manufacturersand brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
