178Vehicle care
If the tyre pressure is to be reduced orincreased, switch off the ignition. Tyre
pressures 3 176, 3 207.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
The tyre pressure monitoring system
valve cores and sealing rings must be
replaced each time the tyres are
changed.
Temperature compensation
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value shown in the
display is the actual tyre pressure.
Therefore it is important to check tyre pressure with cold tyres.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).For 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. Ensure that the direction
of rotation of the wheels is the same
as before.
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.
If wheel rims of a different type are to
be installed, the wheel nuts may also
need to be changed. We recommend you consult your service partner.
Vehicle care183
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-slippery surface. The front wheels must be in the straight-ahead position.
■ Apply the electrical parking brake 3 136 and engage first gear,
reverse gear or P.
■ Remove the spare wheel 3 185.
■ Never change more than one wheel
at a time.
■ Block wheel diagonally opposite the wheel to be changed, by placing
wedge blocks or equivalent in front
and behind the wheel.
■ Use the jack only to change wheels
in case of puncture, not for
seasonal winter or summer tyre
changes.
■ Never exceed jack maximum working load (900 kg).
■ If the ground on which the vehicle is standing is soft, a solid board
(max. 1 cm thick) should be placed
under the jack.■ Do not raise the vehicle more than is necessary to change a wheel.
■ 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 it is raised on the jack.
■ Clean wheel nuts and thread before
mounting the wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Pull off the wheel cover.
2. Install the wheel wrench ensuring that it locates securely and loosen
each wheel nut by one turn by
turning anticlockwise.
3. The location of front and rear jacking points is indicated by
notches on the bottom edge of the
vehicle, under the doors.
184Vehicle care
4. Before positioning the jack, set itto the necessary height by
rotating the eye by hand.
Position jack at the jacking point
located nearest to the wheel concerned so that the jack claw
spans the vertical base. Ensure
the jack is positioned correctly.
The jack base must be on the
ground directly below the jacking
point in a manner that prevents it
from slipping.5. Attach wheel wrench to eye of threaded rod and rotate wrench
clockwise to raise vehicle.
If this is not the case, carefully
lower the vehicle immediately and
reposition the jack. Raise the
vehicle until the wheel is just clear of the ground.
6. Unscrew wheel nuts completely and wipe clean with a cloth.
Do not grease the threads. Put
wheel nuts somewhere where the threads will not be soiled.
7. Change the wheel. Notes on spare wheel 3 185.
8. Screw on the wheel nuts and
tighten slightly by hand by turning
clockwise until wheel is held
against the hub.
9. Rotate wrench anticlockwise and lower vehicle to the ground.
10. Install the wheel wrench ensuring that it locates securely and tighten
each wheel nut in a crosswise
sequence. Tightening torque is
140 Nm.
11. Stow the replaced wheel 3 185
and the vehicle tools 3 173.
12. Check the tyre pressure of the installed tyre as soon as possible.
