252Vehicle careTyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 10 mm to the tyre tread
and the inboard sides (including chain lock).
9 Warning
Damage may lead to tyre blowout.
Tyre chains are only permitted on
tyres of size 215/60 R 16 and
225/50 R 17.
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.
If you have a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is on the left side in
the load compartment behind a cover.
1. Take the tyre repair kit from the compartment.
2. Remove the compressor.

Vehicle care255
Note
The driving characteristics of the
repaired tyre are severely affected, therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
The built-in safety valve opens at a
pressure of 7 bar.
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
The adapters supplied can be used
to pump up other items e.g.
footballs, air mattresses, inflatable
dinghies etc. They are located on the
underside of the compressor. To
remove, screw on compressor air hose and withdraw adapter.Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 252.
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-skid surface. The front wheels
must be in the straight-ahead
position.
■ Apply the parking brake and engage first gear, reverse gear or
P .
■ Remove the spare wheel 3 257.
■ Never change more than one wheel
at once.
■ Use the jack only to change wheels
in case of puncture, not for
seasonal winter or summer tyre
change.
■ If the ground on which the vehicle is standing is soft, a solid board
(max. 1 cm thick) should be placed
under the jack.
■ No people or animals may be in the
vehicle when it is jacked-up.■ Never crawl under a jacked-up vehicle.
■ Do not start the vehicle when it is raised on the jack.
■ Clean wheel nuts and thread with a
clean cloth before mounting the
wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Disengage wheel nut caps with a screwdriver and remove. Pull off

Vehicle care261Jump starting
Do not start with quick charger.
A vehicle with a discharged battery
can be started using jump leads and the 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 battery can alreadyfreeze 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 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.
■ The vehicles must not come into contact with each other during the
jump starting process.■ Apply the parking brake, transmission in neutral, automatictransmission in P.
■ Open the positive terminal protection caps of both batteries.
Lead connection order:
1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged battery.
