tyre repair kit.
Tyre repair kit 3 240.
Wheels and tyres
Tyre condition, wheel condition Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
All tyre sizes are permitted as winter
tyres 3 271.Tyre designations
E.g. 225/55 R 18 98 V225:tyre width, mm55:cross-section ratio (tyre height
to tyre width), %R:belt type: RadialRF:type: RunFlat18:wheel diameter, inches98:load index e.g. 98 is equivalent

Choose a tyre appropriate for the
maximum speed of your vehicle.
Refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents. Optional equipment
could reduce the maximum speed of
the vehicle.

Vehicle care237Directional tyresDirectional tyres should be mounted
so that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol (e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Tyre pressure 3 271.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 268.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 271.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.

Vehicle care2411.Pull speed limit label from the tyre
repair kit and place it in driver's
visible area.
2. Pull the electrical cable and air hose out of the compartments on
the underside of the kit.
3. Turn selector A to the "sealant"
position. Check that switch B is in
position J.
4. Uncoil the air hose fully and
unscrew the cap from the end of
the hose. Connect hose to the
valve of the defective tyre.
5. Connect the electrical cable to the
vehicle's 12 V front power
outlet 3 97.
To avoid discharging the battery,
we recommend running the
engine.
6. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
7. The compressor pressure gauge briefly indicates up to
600 kPa (6 bar) whilst the sealant
cartridge is emptying (approx.
30 s). Then the pressure starts to
drop.
Page 244 of 289

242Vehicle care8. All of the sealant is pumped intothe tyre. Then the tyre is being
inflated.
9. The prescribed tyre pressure should be obtained within ten
minutes.
Tyre pressure 3 271.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within ten minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
ten minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button.
Do not run the compressor longer than ten minutes.
10. Detach the tyre repair kit. Stow tyre repair kit in load
compartment.
11. Remove any excess sealant using a cloth.12. Start driving immediately so thatsealant is evenly distributed in the
tyre. After driving approx.
three miles but no more than ten
minutes, stop and check tyre
pressure. Turn selector on the kit
to the air pump symbol. Connect
compressor air hose to tyre valve. Fill tyre as described before. Drain excess tyre pressure with the
button on the kit.
If tyre pressure hasn't decreased
under 150 kPa (1.5 bar), set it to
the correct value. Otherwise the
vehicle must not be used. Seek
assistance of a workshop. 3 271
Page 245 of 289

Vehicle care243Repeat the checking procedure
once more after driving further
three miles but no more than ten
minutes to check that there is no
more loss of pressure.
If the tyre pressure has fallen
below 150 kPa (1.5 bar), the
vehicle must not be used. Seek
the assistance of a workshop.
13. Stow away tyre repair kit in load compartment.
Notice
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.
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 cartridge. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be
used from approx. -30 °C.
Removing the pipe and cartridge
1. Turn pipe assembly to the left until
it contacts the unit.
2. Disconnect the connector from the cartridge by turning it a quarter
turn anti-clockwise.

Keep the kit vertical and unscrew
the cartridge from the bottom.
5. To fit the new cartridge and new pipe, carry out these operations in
reverse order.
Wheel changing
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.
● If necessary, place a chock under
the wheel diagonally opposite the
wheel to be changed.
● Apply the parking brake and engage first gear, reverse gear or
P .
● 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 vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
Tightening torques
Caution
If the vehicle is equipped with alloy
wheels, tighten the wheel bolts
manually at least for the first five
turns.
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
125 Nm.

252Vehicle careCaution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 50 mph nor further than 60 miles. In all other
cases and when the transmission is
defective, the front axle must be
raised off the ground.
Seek the assistance of a workshop. After towing, unscrew the towing eye.
Insert cap with the flange into the
recess and fix cap by pushing.

Appearance care
Exterior care LocksThe locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use a de-icing agent only
when absolutely necessary, as this
has a degreasing effect and impairs
lock function. After using a de-icing
agent, have the locks regreased by a
workshop.
WashingThe paintwork of your vehicle is
exposed to environmental influences.
Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing.
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can
cause paint damage.If using a vehicle wash, comply with
the vehicle wash manufacturer's instructions. The windscreen wiperand rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Wax painted parts of the vehicle regularly.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
