Vehicle care165
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
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
nominal tyre pressure and make
other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced. 3 1619 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.
Tyre chains
Use tyre chains only on front wheels.
Page 168 of 205

166Vehicle care9Warning
Damage may lead to tyre blowout.
Always use fine mesh chains that add
no more than 10 mm to the tyre tread
and the inboard sides (including chain
lock).
Tyre chains are only permitted on
tyres of size 205/60 R16 and
215/50 R17.
The use of tyre chains is not permitted on the temporary spare wheel.
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.
● 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.
● Clean wheel nuts and thread with
a clean cloth before mounting the wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
Jacking positions
The jacking positions shown refer to
the use of lifting arms and accessory
jacks used for changing winter /
summer tyres.
Rear arm position of the lifting
platform centrically under the recess
of the sill.

168Vehicle care● Never crawl under a jacked-upvehicle.
● Do not start the vehicle when it is
raised on the jack.
● Clean wheel 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. Disengage wheel nut caps with a screwdriver and remove. Pull off
the wheel cover. Vehicle tools
3 159.
Alloy wheels: Disengage wheel
nut caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
2. Fold out the wheel wrench and install 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. Ensure the jack is correctly positioned under the relevant
vehicle jacking point.
4. Set the jack to the necessary height. Position it directly below
Page 171 of 205

Vehicle care169the jacking point in a manner thatprevents it from slipping.
Attach jack handle and with the
jack correctly aligned rotate handle until wheel is clear of theground.
5. Unscrew the wheel nuts.
6. Change the wheel.
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 nut in a crosswise
sequence. Tightening torque is
140 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
Install centre cap on alloy wheels.
11. Install vehicle jacking point cover on versions with sill panels.
12. Stow the replaced wheel, the vehicle tools 3 159 and the
adapter for the locking wheel nuts 3 48.
13. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.Stowing a damaged full size
wheel in the spare wheel well
A damaged full size wheel must be
stowed outside up in the spare wheel
well secured with the wing nut.
The floor cover can be placed on the
projecting wheel.
Stowing the spare wheel back in
the well after replacing the
damaged wheel
1. Open the floor cover, loosen and remove wing nut.
2. Place the tools in the tool box or the tool bag 3 159.

Vehicle care171● A discharged vehicle battery canalready freeze at a temperature
of 0 °C. Defrost the frozen vehicle battery before connecting jump
leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
● Use a booster vehicle battery with the same voltage ( 12 Volts).
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
.
● 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.
● The vehicles must not come into contact with each other during
the jump starting process.● Apply the parking brake, transmission in neutral,
automatic transmission in P.
● Open the positive terminal protection caps of both vehicle
batteries.
Lead connection order:
1. Connect the red lead to the positive terminal of the booster
vehicle battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged vehicle battery.
3. Connect the black lead to the negative terminal of the booster
vehicle 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
vehicle 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.
