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. 
Check after 10 minutes of driving
Screw the inflator tube ⇒ Fig. 146 5 again and check the pressure on the
gauge 6.
1.3 bar (19 psi / 130 kPa) and lower:
● Stop the vehicle! The tyre cannot be sealed sufficiently with the tyre mo-
bility set.
● You should obtain professional assistance ⇒ 
.
1.4 bar (20 psi / 140 kPa) and higher:
● Set the tyre pressure to the correct value again ⇒ page 210.
● Carefully resume your journey until you reach the nearest specialised
workshop without exceeding 80 km/h (50 mph).
● Have the damaged tyre replaced. 

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. 

Practical information
CAUTION
● Always carefully remove the fuse box covers and refit them correctly to
avoid problems with your vehicle.
● 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
In the vehicle, there are more fuses than those indicated in this chapter.
These should only be changed by a Specialised workshop. 
Replacing a blown fuse
Fig. 149 Image of a
blown fuse
Preparation
● Switch off the ignition, lights and all electrical equipment.
● Open the corresponding fuse box ⇒ page 262. Identifying a blown fuse
A fuse is blown if its metal strip is ruptured
⇒ Fig. 149.
Point a lamp at the fuse. This will make it easier to see if the fuse is blown.
To replace a fuse
● Remove the fuse.
● Replace the blown fuse for one with an identical amperage rating (same
colour and markings) and identical size ⇒ 
.
● Replace the cover again or close the fuse box lid.
CAUTION
If you replace a fuse with higher-rating fuse, you could cause damage to an-
other part of the electrical system. 

Information for replacing bulbs
Checklist
To replace a bulb, carry out the following operations always in the order giv-
en ⇒ 
:
1. Park the vehicle a safe distance from traffic and on suitable ground.
2. Apply the handbrake firmly ⇒ page 134.
3. Turn the light switch to position 0 ⇒ page 84.
4. Move the gear lever into the neutral position ⇒ page 84.
5. Stop the engine and remove the key from the ignition ⇒ page 119.
6. Automatic gearbox: move the selector lever to position P
⇒ page 124.
7. Manual gearbox: Select a gear ⇒ page 124.
8. Allow the corresponding bulb to cool.
9. Visually inspect fuses to see if any are blown ⇒ page 261.
10. Replace the bulb according to the instructions ⇒ 
. Bulbs should
only be replaced by new identical models. Bulb information is dis-
played on the bulb socket or on the bulb itself.
11. In general, never touch the bulb glass directly. The heat of the bulb would cause the fingerprint to evaporate and condense on the reflec-
tor. This will impair the brightness of the headlight.
12. Check if the new bulb is working. If the bulb is not working, it maynot have been correctly fitted, it could be damaged or the connector
may not be correctly connected.
13. Every time a bulb for the headlights is replaced, visit a specialised workshop to check the headlights.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.
CAUTION
Always remove and fit headlights carefully to avoid damage to the paint-
work and other vehicle parts. 

Practical information
Starting assistance
Introduction
If the engine fails to start because of a discharged battery, the battery of an-
other vehicle can be used to start the engine. Before starting, check the
magic eye on the battery ⇒ page 193.
For starting assistance, jump lead cables conforming to the standard
DIN 72553 are required (see the cable manufacturer instructions). The cable
section in vehicles with petrol engine must be at least 25 mm 2
.
Additional information and warnings:
● Working in the engine compartment ⇒ page 180
● Vehicle battery ⇒ page 193
WARNING
Incorrect use of jump leads and incorrectly jump starting could cause the
battery to explode resulting in serious injury. Please observe the follow-
ing rules to minimise the risk of a battery explosion:
● All work involving the vehicle battery and electrical system can cause
corrosion, fire and serious electric shocks. Always read and take into ac-
count the safety warnings and standards before beginning work on the
battery ⇒ page 193, Vehicle battery.
● The battery providing current must have the same voltage (12V) and
approximately the same capacity (see markings on battery) as the flat
battery.
● Never charge a frozen or recently thawed battery. A flat battery can al-
so freeze at temperatures close to 0 °C (+32 °F).
● If a battery is frozen and/or has been frozen then it must be replaced.
WARNING (Continued)
● A highly explosive mixture of gases is released when the battery is
being charged. Always keep lit cigarettes, open flames, sparks and fire
far from the battery. Never use a mobile telephone when connecting and
removing the jump leads.
● Charge the battery only in well ventilated areas given that when the
battery is charged by outside assistance, it creates a mix of highly explo-
sive gases.
● Jump leads should never enter into contact with moving parts in the
engine compartment.
● Never switch the positive and negative poles or connect the jump
leads incorrectly.
● Note the Instruction Manual provided by the manufacturer of the
jump leads.
CAUTION
To avoid considerable damage to the vehicle electrical system, note the fol-
lowing carefully:
● If the jump leads are incorrectly connected, this could result in a short
circuit.
● The vehicles must not touch each other, otherwise electricity could flow
as soon as the positive terminals are connected. 
