16. Continue driving immediately sothat sealant is evenly distributed
in the tyre. After driving approx.
three miles but no more than ten
minutes, stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve when
doing this. Fill tyre as described
before. Drain excess tyre
pressure with the button on the air
hose.
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. 3 263
Repeat 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.
17. 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 min.
The built-in safety valve opens at a
pressure of seven bar (102 psi).
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 bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
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 orP .
● 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.

242Vehicle care● Note that the spare wheel issecured by the conical contact ofeach bolt if the wheel bolts for the alloy wheels are used. In this
case, the washers do not come
into contact with the spare wheel.
1. Disengage wheel bolt caps with the wheel bolt cover remover.
3 230
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with the wheel bolt cover
remover.2. Attach the wheel wrench and loosen each wheel bolt 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 tool box. 3 230
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
the jacking point in a manner that
prevents it from slipping.

Vehicle care243Ensure that the edge of the body
fits into the notch of the jack.
With the jack correctly aligned
rotate wheel wrench until wheel is
clear of the ground.
5. Unscrew the wheel nuts.
6. Change the wheel. Spare wheel 3 240.
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 bolt in a crosswise
sequence. Tightening torque is
115 Nm.
If the vehicle is equipped with
alloy wheels, note that the wheel
bolts can also be used for the steel spare wheel. In this case, the
spare wheel is secured by the
conical contact of each bolt.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
11. Stow the replaced wheel 3 240,
the vehicle tools 3 230 and the
adapter for the locking wheel nuts.
12. Check the tyre pressure of the installed tyre and the wheel nuttorque as soon as possible.Jump starting
Do not start with quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● Never expose the vehicle battery
to naked flames or sparks.
