1. Open the lid of the tyre repair kit.
2. Peel off the label Ishowing the
maximum permissible speed of
80 km/h (50 mph) from the casing
and attach it to the instrument panel
in the driver’s field of view. Make sure
the label does not obscure anything
important.
3. Take the hose Cand the power plug

4. Unscrew the orange cap Dand the
bottle lid J.
5. Screw the sealant bottle Kclockwise
into the bottle holder Efully tight.
6. Remove the valve cap from the damaged tyre.
7. Detach the protective cap Afrom the
hose Cand screw the hose Cfirmly
onto the valve of the damaged tyre.
8. Make sure that the compressor switch
His in position 0.
9. Insert the power plug Ginto the cigar
lighter socket or auxiliary power
socket. See Cigar lighter (page 97).
See Auxiliary power sockets
(page 97).
10. Start the engine.

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.

TyreC
Run flat tyre Wheel rim position with correct

A
Wheel rim position with

B

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.

Wheels and tyresBACE75207 BDCAE87667
WARNINGS
Do not fit a mixture of run flat and
standard tyres. In isolated cases, a
standard tyre can be temporarily
mounted on a vehicle otherwise equipped
with run flat tyres. It must be pointed out
to the driver that the standard tyre has no
runflat properties. Do not fit run flat tyres on vehicles
that were not originally fitted with
them. Please contact your dealer
for more details regarding compatibility. Run flat tyres may be sold and mounted
only by specially trained and certified tyre
dealers.
TYRE CARE
To make sure the front and rear tyres of
your vehicle wear evenly and last longer,
we recommend that you swap the tyres
from front to rear and vice versa at regular
intervals of between 5 000 and 10 000
km (3 000 and 6 000 miles).
CAUTION
Do not scrub the sidewalls of the
tyres when you are parking.
If you have to mount a kerb, do so slowly
and approach it with the wheels at
right-angles to the kerb. Examine the tyres regularly for cuts,
foreign objects and uneven wear of the
tread. Uneven wear could mean that the
wheel alignment is outside specification.
Check the tyre pressures (including the
spare) when cold, every two weeks.
USING WINTER TYRES
CAUTION
Make sure that you use the correct
wheel nuts for the type of wheel the
winter tyres are fitted to.
If winter tyres are used, make sure that
the tyre pressures are correct. See
Technical specifications
(page 168).
USING SNOW CHAINS WARNINGS
Do not exceed 40 km/h (25 mph)
when using 14 mm ( 0.6 inch) snow
chains or 50 km/h (30 mph) when
using 10 mm ( 0.4 inch) snow chains. Do not use snow chains on
snow-free roads.
Only fit snow chains to 235/60 R16
or 215/65 R16 tyres.
CAUTION
If your vehicle is fitted with wheel
trims, remove them before fitting
snow chains.
Note:The ABS will continue to operate
normally.
Only use small link snow chains.
Only use snow chains on the front wheels.

Vehicles with stability control
(ESP)
Vehicles with stability control (ESP) may
exhibit some unusual driving
characteristics which can be avoided by
switching the system off. See
Using
stability control (page 113).
TYRE PRESSURE
MONITORING SYSTEM WARNINGS
The system does not relieve you of
your responsibility to regularly check
the tyre pressures.
The system will only provide a low
tyre pressure warning. It will not
inflate the tyres.
Do not drive on significantly
under-inflated tyres. This may cause
the tyres to overheat and fail.
Under-inflation reduces fuel efficiency,
tyre tread life and may also affect your
ability to drive the vehicle safely. CAUTIONS
Do not bend or damage the valves
when you are inflating the tyres.
Have tyres installed by properly
trained technicians.
The Deflation Detection System will alert
you if there is a change of air pressure in
any tyre. It does this by using the ABS
sensors to detect the rolling
circumference of the wheels. When the
circumference changes, this indicates low
pressure in a tyre, a warning message is
displayed in the information display and
the message indicator will illuminate. See
Information messages
(page 73).Apart from a too low tyre pressure or a
damaged tyre, the following situations can
affect the rolling circumference:
•
Vehicle load is uneven.
• When using a trailer or travelling up
and down an incline.
• Using snow chains.
• Driving on soft surfaces such as snow
or mud.
Note:The system will still function
correctly, but there may be an increased detection time.
If a low pressure warning message is
displayed in the information display, check
the tyre pressures as soon as possible
and inflate them to the recommended
pressure. See Technical
specifications (page 168).
If this happens frequently, have the cause
determined and rectified as soon as
possible.
System reset
Note:
Do not reset the system when the
vehicle is moving.
Note:You should reset the system
following any adjustment to the tyre pressures or any changing of tyres.
Note:Turn the ignition on.
