236Vehicle careFor safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Tyres age, even if they are not used.
We recommend tyre replacement
every six years.
Changing tyre and wheel size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the tyre
deflation detection system and make
other vehicle modifications.
Tyre deflation detection system
3 234.
Have the label with tyre pressures
replaced.9 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.
Wheel 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.

Vehicle care237Tyre 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 all tyres
sizes allowed for the vehicle.
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.
Open the cover of the footwell storage
3 76.
The tyre repair kit is located in the
stowage compartment underneath
the right front seat.
1. Remove the sealant bottle and the
compressor.
2. Pull speed limit label from sealant
bottle and place it in driver's
visible area.

2. Fit the wheel wrench on one
hexagon bolt. Turn it
anticlockwise until the spare wheel holder is low enough allow
the catch to be unhooked.
3. Lift the spare wheel holder and unhook the catch.
Lower the spare wheel holder.
4. Remove the spare wheel.
5. Change the wheel.
6. Position the damaged wheel with the outside down in the spare
wheel holder.
7. Lift the spare wheel holder and engage in the catch. The open
side of the catch must point in the
direction of travel.
8. Close the spare wheel holder by turning the hexagon bolt
clockwise using the wheel
wrench.
9. Stow wheel wrench in the storage.
10. Close the tailgate or the rear doors.
Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
Fitting the spare wheel
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.

244Vehicle caresecurely 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. 3 232
3. Ensure the jack is correctly
positioned under the relevant
vehicle jacking point.
4. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Ensure that the edge of the body
fits into the notch of the jack.
Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
5. Unscrew the wheel nuts. 6. Change the wheel. Spare wheel 3 241.
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuring that it is located securely and
tighten each bolt in a crosswise

115 Nm.
If the vehicle is equipped with
alloy wheels, note that the wheel
bolts can also be used for the steel spare wheel. In this case, the
spare wheel is secured by the
conical contact of each bolt.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
11. Stow the replaced wheel 3 241,
the vehicle tools 3 232 and the
adapter for the locking wheel nuts.
12. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.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.
