IF A TYRE IS
PUNCTURED
GENERAL INSTRUCTIONS
Wheel changing and correct use of the
jack and space-saver spare wheel call for
some precautions as listed below.
BUMP STARTING
Never bump start the engine (by pushing,
towing, or coasting downhill) as this could
cause fuel to flow into the catalytic ex-
haust system and damage it beyond repair.
Remember that the brake booster and the
power steering system are not operating
until the engine is started, a greater effort
will therefore be required to press the
brake pedal or to turn the steering wheel.
Alert other drivers that the
car is stationary in compli-
ance with local regulations: hazard
warning lights, warning triangle etc.
Any passengers on board should leave
the car, especially if it is heavily laden.
Passengers should stay away from on-
coming traffic while the wheel is be-
ing changed on. If the wheel is being
changed on a steep or badly surfaced
road, place the wedges or other suit-
able material under the wheel to stop
the car.
WARNING
The space-saver spare wheel
is specific to your car, do not
use it on other models, or use the
spare wheel of other models on your
car. The space-saver spare wheel
shall only be used in an emergency.
It shall only be used for the distance
necessary to reach a service point and
the car speed shall not exceed 80
Km/h. The spare wheel has an orange
sticker that summarises the main cau-
tions for use and limitations. The
sticker should never be removed or
covered.
Never fit a wheel cap on a space-
saver spare wheel. The sticker gives
the following information in four lan-
guages: caution! For temporary use
only! 80 km/h max! Replace by nor-
mal wheel as soon as possible. Do not
cover this label.

WHEN NEEDING TO
CHANGE A BULB
GENERAL INSTRUCTIONS
❒When a light is not working, check
that the corresponding fuse is intact
before changing a bulb. For the loca-
tion of fuses, refer to the paragraph “If
a fuse blows” in this section;
❒Before changing a bulb check the con-
tacts for oxidation;
❒Burnt bulbs must be replaced by oth-
ers of the same type and power;
❒Always check the height of the head-
light beam after changing a bulb.Halogen bulbs must be han-
dled touching only the metal-
lic part. If the transparent bulb
is touched with the fingers, its
lighting intensity is reduced and life of
the bulb may be compromised. If
touched accidentally, rub the bulb with
a cloth moistened with alcohol and al-
low to dry.
Modifications or repairs to
the electrical system (elec-
tronic control units) carried out in-
correctly and without bearing the fea-
tures of the system in mind can cause
malfunctions with the risk of fire.
WARNING
Halogen bulbs contain pres-
surised gas which, if broken,
may cause small fragments of glass to
be projected outwards.
