252Vehicle careTyres 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 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 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.
Vehicles with steel wheels: When
using locking wheel nuts, do not
attach wheel covers.

Vehicle care253Tyre 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 R16 and
225/50 R17.
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 the tyre's sidewall cannot be
repaired with the tyre repair kit.9 Warning
Do not drive faster than 50 mph.
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.

2. Fold out the wheel wrench andinstall ensuring that it locates
securely 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 glovebox.3. Some versions may have covered
the vehicle jacking point. Pull out
the cover sideways.
4. Ensure the jack is correctly positioned under the relevant
vehicle jacking point.
5. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.

Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
6. Unscrew the wheel nuts. 7. Change the wheel. Spare wheel 3 258
8. Screw on the wheel nuts.
9. Lower vehicle.
10. Install the wheel wrench ensuring that it locates securely and tighten
each nut in a crosswise
sequence. Tightening torque is
140 Nm.
11. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
12. Install vehicle jacking point cover.
13. Stow the replaced wheel 3 258,
the vehicle tools 3 246 and the
adapter for the locking wheel nuts
3 66.
14. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.
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
3 253.
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,
Page 261 of 307
Vehicle care259even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
The spare wheel has a steel rim.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.
The spare wheel is located in a holder
beneath the vehicle floor.
1. Open the storage in the load compartment 3 246.
2. Remove both caps above the hexagon bolts.
3. Fit the wheel wrench on one hexagon bolt and turn it
anticlockwise until a resistance is
noticeable.
4. Proceed with the other hexagon bolt in the same way.5. Lift the spare wheel holder andunhook both catches.
6. Lower the spare wheel holder.
7. Detach the safety cable.

8. Lower holder all the way andremove spare wheel.
9. Change the wheel. The damaged wheel must be
secured in the load compartment,
see below.
10. Lift the empty spare wheel holder and insert the safety cable.
11. Lift the spare wheel holder further
and engage in both catches. The
open sides of the catches must
point in the direction of travel.
12. Close the empty spare wheel holder by turning both hexagon
bolts clockwise using the wheel
wrench.
13. Fit the caps above both hexagon bolts.
14. Stow wheel wrench and the jack in the storage in front of the
tailgate.
15. Close the storage compartment cover.
When stowing the spare wheel in the
spare wheel holder, note that the
wheel is positioned with the tyre valve
above the recess of the wheel holder.
Stowing a damaged wheel in the
load compartment
The spare wheel holder is not
designed for other tyre sizes than the
spare wheel.
A damaged wheel wider than the
spare wheel must be stowed in the
load compartment and secured with a strap. Vehicle tools 3 246.
The seats of the third row must be
folded down 3 79.
1. Position the wheel close to the left
sidewall of the load compartment.
2. Place the loop end of the strap through the front lashing eye on
the left side.
3. Place the hook end of the strap through the loop and pull it until
the strap is fastened securely to
the lashing eye.

Vehicle care2633. Connect the black lead to thenegative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as far away from the discharged
battery as possible, however at
least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After five minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of one
minute.
3. Allow both engines to idle for approx. three minutes with the
leads connected.4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Insert a screwdriver in the slot at the
short edge of the cap. Release the
cap by carefully moving the
screwdriver sidewards. To prevent
damage it is recommended to place a cloth between the screwdriver and
the frame.
The towing eye is stowed with the vehicle tools 3 246.
