Anti-puncture kit*
Introduction
The Tyre Mobility Set* will reliably seal punctures caused by the penetration
of a foreign body of up to about 4 mm in diameter. Do not remove foreign
objects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre, you must again check the tyre
pressure about 10 minutes after starting the engine.
You should only use the tire mobility set if the vehicle is parked in a safe
place, you are familiar with the procedure and you have the necessary tire
mobility set! Otherwise, you should seek professional assistance.
The tyre sealant must not be used in the following cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20 °C (-4 °F).
● In the event of cuts or perforations in the tyre greater than 4 mm.
● If you have been driving with very low pressure or a completely flat tyre.
● If the sealant bottle has passes its use by date.
Additional information and warnings:
● Vehicle key set ⇒ page 28
● Braking, stopping and parking ⇒ page 134
● Wheels and tyres ⇒ page 210
● In case of emergency ⇒ page 240
● Wheel trims ⇒ page 248
WARNING
Using the tire mobility set can be dangerous, especially when filling the
tyre at the roadside. Please observe the following rules to minimise the
risk of injury:
● Stop the vehicle safely as soon as possible. Park your vehicle as safe
distance from surrounding traffic to fill the tyre.
● Ensure the ground on which you park is flat and solid.
● All passengers and particularly children must keep a safe distance
from the work area.
● Turn on the hazard warning lights to warn other road users.
● Use the tire mobility set only if you are familiar with the necessary
procedure. Otherwise, you should seek professional assistance.
● The tire mobility set is intended for temporary, emergency use only.
Use only until you can reach the nearest specialised workshop.
● Replace the repaired tyre with the tire mobility set as soon as possi-
ble.
● The sealant is a health hazard and must be cleaned immediately if it
comes into contact with the skin.
● Always keep the tire mobility set out of the reach of small children.
● Never use the approved jack, even if it has been approved for your ve-
hicle.
● Always stop the engine, apply the handbrake lever firmly and engage
gear if using a manual gearbox, in order to reduce the risk of vehicle in-
voluntary movement.
WARNING
A tyre filled with sealant does not have the same performance properties
as a conventional tyre.
● Never drive faster than 80 km/h (50 mph). 

257
Practical information
WARNING (Continued)
● Avoid heavy acceleration, hard braking and fast cornering.
● Drive only during 10 minutes at a maximum speed of 80 km/h
(50 mph) and subsequently check the tyre.

Practical information
● Start the vehicle engine and leave it running.
● Attach the connector ⇒ Fig. 146 9
to a 12 volt socket of the vehicle
⇒ page 117.
● Connect the air compressor with the ON/OFF switch ⇒ Fig. 146 8
.
● Keep the air compressor running until it reaches 2.0 to 2.5 bar
(29-36 psi / 200-250 kPa) ⇒ 
. Maximum operation time 8 minutes ⇒ .
● Disconnect the air compressor.
● If it is not possible to achieve an air pressure of 2.0 to 2.5 bar
(29-36 psi / 200-250 kPa), unscrew the tyre inflator tube from the tyre valve.
● Move the vehicle some 10 metres forwards or backwards so that the
sealant is evenly distributed in the tyre interior.
● Securely screw the compressor tyre inflator tube into the tyre valve and
repeat the inflation process.
● If the indicated pressure can still not be reached, the tyre is too badly
damaged. The tyre cannot be sealed with the anti-puncture kit. Do not con-
tinue driving. You should obtain professional assistance ⇒ 
.
● Disconnect the air compressor and unscrew the flexible inflator tube
from the tyre valve.
● When the tyre pressure is between 2.5 and 2.0 bars, immediately con-
tinue driving without exceeding 80 km/h (50 mph).
● After 10 minutes, Check the pressure again ⇒ page 259.
WARNING
When inflating the wheel, the air compressor and the inflator tube may
become hot.
● Protect hands and skin from hot parts.
● Do not place the hot flexible inflator tube or hot air compressor on
flammable material.
WARNING (Continued)
● Allow them to cool before storing the device.
● If it is not possible to inflate the tyre to at least 2.0 bars (29 psi /
200 kPa), the tyre is too badly damaged. The sealant is not in a good con-
dition to seal the tyre. Do not continue driving. You should obtain profes-
sional assistance.
CAUTION
Switch off the air compressor after a maximum of 8 operational minutes to
avoid overheating! Before switching on the air compressor again, let it cool
for several minutes. 

Practical information
Fuses
Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, an electrical component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. +If a
newly inserted fuse blows after a short time, you must have the electrical
system checked by a Specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 180
WARNING
The high voltages in the electrical system can give serious electrical
shocks, causing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out fuses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another part of the electrical system.
● Protect the fuse boxes when open to avoid the entry of dust or humidity.
Dirt and humidity inside fuse boxes can cause damage to the electrical sys-
tem.
Note
One single consumer could have more than one fuse.
Note
Several consumers could run over one single fuse. 
