GENERAL INFORMATION
CAUTIONS
Use only approved wheel and tyre
sizes. Using other sizes could
damage the vehicle and will make
the National Type Approval invalid. If you change the diameter of the
tyres from that fitted at the factory,
the speedometer may not display
the correct speed. Take the vehicle to
your dealer to have the engine
management system reprogrammed. A decal with tyre pressure data is located
in the driver’s door opening at the B-pillar.
Check and set the tyre pressure at the
ambient temperature in which you are
intending to drive the vehicle and when
the tyres are cold.
CHANGING A ROAD WHEEL
Locking wheel nuts
You can obtain a replacement locking
wheel nut key and replacement locking
wheel nuts from your dealer using the
reference number certificate.
Vehicles with a temporary
spare wheel
WARNINGS
If the spare wheel differs from the
other fitted wheels, these rules must
be followed:
Do not exceed 80 km/h (50 mph).
Drive the shortest possible
distances.
Do not fit more than one spare
wheel on your vehicle at any one
time. WARNINGS
Do not use snow chains on this type
of wheel.
Do not drive through an automatic
car wash.
Do not carry out any tyre repairs on
a temporary spare wheel.
CAUTION
The ground clearance of your vehicle
will be reduced. Take care when
parking next to a kerb.
Note:Your vehicle may exhibit some
unusual driving characteristics.
Vehicle jack WARNINGS
The vehicle jack supplied with your
vehicle should only be used when
changing a wheel in emergency
situations. Before using the vehicle jack, check
that it is not damaged or deformed
and that the thread is lubricated and
free from foreign matter. Never place anything between the
jack and the ground, or the jack and
the vehicle.
Note:
Vehicles with a tyre repair kit or run
flat tyres are not equipped with a vehicle jack or a wheel brace.
It is recommended to use a workshop
type hydraulic jack for changing between
summer and winter tyres.
Note:
Use a jack with a minimum lifting
capacity of 1.5 tonnes and a lifting plate with a minimum diameter of 80 millimetres(3.1 inches).

7. Install the wheel trim using the ball of
your hand. WARNING
Have the wheel nuts checked for
tightness and the tyre pressure
checked as soon as possible.
Note:If the spare wheel is different in size
or construction to the road wheels, have this replaced as soon as possible.
TYRE REPAIR KIT
Your vehicle is not equipped with a spare
tyre, but does include an emergency tyre
repair kit that can be used to repair one
flat tyre.
The tyre repair kit is located in the
underfloor storage compartment. See
Storage compartments (page 98).
General information WARNINGS
Depending on the type and extent
of tyre damage, some tyres can
only be partially sealed or not sealed
at all. Loss of tyre pressure can affect
vehicle handling, leading to loss of vehicle
control. Do not use the tyre repair kit if the
tyre has already been damaged as
a result of being driven under
inflated. Do not use the tyre repair kit on run
flat tyres.
Do not try to seal damage other
than that located within the visible
tread of the tyre.
Do not try to seal damage to the
tyre’s sidewall. The tyre repair kit seals most tyre
punctures [with a diameter of up to six
millimetres (1/4 inch)] to temporarily
restore mobility.
Observe the following rules when using
the kit:
•
Drive with caution and avoid
making sudden steering or
driving manoeuvres, especially if
the vehicle is heavily loaded or you are
towing a trailer.
• The kit will provide you with an
emergency temporary repair, enabling
you to continue your journey to the
next vehicle or tyre dealer, or to drive
a maximum distance of
200 kilometres (125 miles).
• Do not exceed a
maximum speed
of 80 km/h (50 mph).
• Keep the kit out of the reach of
children.
• Only use the kit when the ambient
temperature is between –30°C (-22°F)
and +70°C (+158°F).
Using the tyre repair kit WARNINGS
Compressed air can act as an
explosive or propellant.
Never leave the tyre repair kit
unattended while in use.
CAUTION
Do not keep the compressor
operating for more than 10 minutes.
Note:
Use the tyre repair kit only for the
vehicle with which it was supplied.

14.
Quickly unscrew the hose Cfrom
the tyre valve and replace the
protective cap A. Fasten the valve
cap again.
15. Leave the sealant bottle Kin the
bottle holder E.
16. Make sure the kit, the bottle lid and the orange cap are stored safely, but
still easily accessible in the vehicle.
The kit will be required again when
you check the tyre pressure.
17. Immediately drive approximately three kilometres (two miles) so that
the sealant can seal the damaged
area.
Note:When pumping in the sealant
through the tyre valve, the pressure may rise up to 6 bar (87 psi) but will drop againafter about 30 seconds. WARNING
If you experience heavy vibrations,
unsteady steering behaviour or
noises while driving, reduce your
speed and drive with caution to a place
where it is safe for you to stop the vehicle.
Recheck the tyre and its pressure. If the
tyre pressure is less than 1.3 bar (19 psi)
or if there are any cracks, bumps or similar
damage visible, do not continue driving
with this tyre. Checking the tyre pressure
1. Stop the vehicle after driving
approximately three kilometres
(two miles). Check, and where
necessary, adjust the pressure of the
damaged tyre.
2. Attach the kit and read the tyre pressure from the pressure gauge F.
3. If the pressure of the sealant-filled tyre
is 1.3 bar (19 psi) or more, adjust it to
the specified pressure. See
Technical specifications (page
168). 4. Follow the inflation procedure once
again to top up the tyre.
5. Check the tyre pressure again from the pressure gauge F. If the tyre
pressure is too high, deflate the tyre
to the specified pressure using the
pressure relief valve B.
6. Once you have inflated the tyre to its correct tyre pressure, move the
compressor switch Hto position 0,
remove the power plug Gfrom the
socket, unscrew the hose C, fasten
the valve cap and replace the
protective cap A.
7. Leave the sealant bottle Kin the bottle
holder Eand store the kit away safely
in its original location.
8. Drive to the nearest tyre specialist to get the damaged tyre replaced.
Before the tyre is removed from the
rim, inform your tyre dealer that the
tyre contains sealant. Renew the kit
as soon as possible after it has been
used once.
Note:
Remember that emergency
roadside tyre repair kits only provide temporary mobility. Regulationsconcerning tyre repair after usage of tyrerepair kit may differ from country tocountry. You should consult a tyrespecialist for advice. WARNING
Before driving, make sure the tyre
is adjusted to the recommended
inflation pressure. See
Technical
specifications (page 168). Monitor the
tyre pressure until the sealed tyre is
replaced. Empty sealant bottles can be disposed
of together with normal household waste.
Return remains of sealant to your dealer
or dispose of it in compliance with local
waste disposal regulations.

B
TyreC
Run flat tyre Wheel rim position with correct
tyre pressure
A
Wheel rim position with
insufficient tyre pressure
B
TyreC
Reinforced sidewall
D When a standard tyre experiences a
drastic loss of inflation pressure, the rim
of the wheel brings the full weight of the
vehicle to bear on the collapsed sidewalls.
You can barely manoeuvre the vehicle
and the tyre is destroyed.
Run flat tyres have sturdy, reinforced
sidewalls that support the rim should the
tyre suffer a loss of inflation pressure.
What to do if a run flat tyre has
a puncture
Due to the run-flat properties of these
tyres, you may not notice any tyre defect.
Your vehicle is equipped with a tyre
pressure monitoring system that alerts
you to any drop in tyre pressure. See
Technical specifications
(page 168).
In the event of a tyre defect:
• immediately slow down to a maximum
speed of 80 km/h (50 mph)
• avoid sudden or erratic braking and
steering manoeuvres and be
especially careful negotiating bends
• do not drive more than 80 kilometres
(50 miles) after the defect is detected
• have the defective tyre replaced as
soon as possible.
Replacing run flat tyres WARNINGS
Make sure that the workshop is
aware that your vehicle is equipped
with special run flat tyres.
Never repair or reuse run flat tyres
that are damaged or have been
driven on run flat.
If a run flat tyre has to be replaced, have
the respective wheel rim inspected for
any damage.
