168Vehicle care
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.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 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
speedometer as well as the nominal
tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
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.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 15 mm to the tyre tread
and the inboard sides (including chain lock).

172Vehicle care● Remove the spare wheel 3 173.
● Never change more than one wheel at a time.
● Use the jack only to change wheels in case of puncture, not
for a 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.
● Take heavy objects out of the vehicle before jacking up.
● 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 engine when the vehicle is raised on the jack.
● Clean wheel bolts/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. Remove the wheel cover (using the hook supplied). Vehicle tools
3 163.
2. Loosen each of the wheel bolts by
half a turn using the wheel
wrench. Ensure the wrench
locates securely. The wrench
should turn anticlockwise to
loosen the bolts. Invert the wrench if necessary.
3. Place lifting pad spigot of the jack
under the jacking hole located
nearest the wheel concerned.
Ensure the jack is positioned
correctly. The jack base must be
on the ground directly below the
jacking hole in a manner that
prevents it from slipping.
4. Install wrench onto the jack and raise the vehicle by turning the
wrench until the wheel is clear of
the ground.
5. Unscrew wheel bolts completely by turning anticlockwise and wipe
clean with a cloth.

Vehicle care173Put wheel bolts somewhere
where the threads will not be
soiled.
6. Change the wheel. Spare wheel 3 173.
7. Screw in the wheel bolts.
8. Lower the vehicle and remove jack.
9. Tighten each of the wheel bolts in
a crosswise sequence using the
wheel wrench. Ensure the wrench
locates securely. The wrench
should turn clockwise to tighten
the bolts. Invert the wrench if
necessary.
Tightening torque is 160 Nm.
10. Replace the wheel cover, ensuring that the valve hole in thewheel cover is aligned with the
tyre valve before installing.
Notice
If applicable, fit anti-theft bolts
nearest the tyre valve (otherwise it
may not be possible to refit the wheel
cover).11. Stow the replaced wheel 3 173
and the vehicle tools 3 163.
12. Have the new wheel balanced on the vehicle.
Check the tyre pressure of the
installed tyre 3 198.
Check the wheel bolt torque.
Have the defective tyre renewed or
repaired as soon as possible.
Spare wheel
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 169.
If mounting a spare wheel which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
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.

Vehicle care175● 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.
● The vehicles must not come into contact with each other during
the jump starting process.● Apply the parking brake, transmission in neutral.
● Open the positive terminal protection caps of both batteries.
The battery is located in the engine
compartment.
Remove cover to access the battery.
Lead connection order:
1. Connect the red lead to the positive terminal (1) of the booster
battery.
2. Connect the other end of the red lead to the positive terminal (2) of
the discharged battery.
3. Connect the black lead to the negative terminal (3) of the
booster battery.
4. Connect the other end of the black
lead to a vehicle grounding point
(4), such as the engine block or an
engine mounting bolt. Connect as
