138Vehicle care
Put wheel bolts somewhere
where the threads will not be
soiled.
6. Change the wheel.
7. Screw in the wheel bolts.
8. Lower vehicle.
9. Tighten each wheel bolt in a crosswise sequence. Tighteningtorque is 140 Nm.
10. Refit wheel cover
11. Change the wheel.
12. Stow the replaced wheel 3 138
and the vehicle tools 3 131.
13. Have the new wheel balanced on the vehicle. Check the tyre
pressure of the installed tyre
3 163 and also the wheel bolt
torque as soon as possible.
Have the defective tyre renewed or
repaired.
Spare wheel Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 133.Use of a spare wheel that is smaller
than the other wheels or together with winter tyres could affect driveability.
Have the defective tyre replaced as
soon as possible.
The spare wheel is mounted under
the rear underbody and may be
secured using a security bolt that can
only be removed using the tool
supplied.
9 Warning
Due to the weight of the tyre
assembly, exercise caution when
releasing the spare wheel carrier.
Do not fully remove bolt 1.
Support the spare wheel with a
suitable object to prevent the
wheel falling suddenly when
loosening the carrier bolts - risk of injury!
It may be necessary to jack the
vehicle up to gain access to the spare wheel on a fully loaded vehicle with a
flat rear tyre.
To release the spare wheel carrier,
loosen bolt 1, ensuring it is not fully
removed. Fully remove bolt 2, then
pull the carrier to the left, until it clears bolt 1, and lower the carrier assembly.
When installing the wheel ensure that
the spare wheel carrier is correctly
positioned before tightening the bolts.
Vehicle care139
Summer and winter tyresIf you use winter tyres, the sparewheel may still be fitted with a
summer tyre.
If you use the spare wheel when it is
fitted with a summer tyre the vehicle's driveability may be affected,
especially on slippery road surfaces.
Directional tyres Fit directional tyres such that they roll
in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
The following applies to tyres fitted
opposing the rolling direction:
■ Driveability may be affected. Have the defective tyre renewed or
repaired as soon as possible.
■ Do not drive faster than 50 mph.
■ Drive particularly carefully on wet and snow-covered road surfaces.
Jump starting Do not start with a quick charger.A vehicle with a discharged 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 battery to naked
flames or sparks.
■ A discharged vehicle battery canalready 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 volts). Its capacity(Ah) must not be much less than
that of the discharged 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 battery during jump starting.
■ Do not allow the terminals of one lead to touch those of the other
lead.
Service and maintenance147
The service display, located in the
Driver Information Centre, indicates
when the next service is due. Seek
the assistance of a workshop.
Service display 3 67.
Engine oil level monitor 3 67.Recommended fluids,
lubricants and parts
Recommended fluids andlubricants Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifications will not be covered by
the warranty.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 have to be used.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 152.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 152.
