Wh
at to do first ●
Park the vehicle on a horizontal surface
and in a saf e p
lace as far away from traffic as
possible.
● Apply the handbrake.
● Switch on the hazard warning lights.
● Manual gearbox: select the 1s
t gear.
● Automatic gearbox: Move the sel
ector lever
to position P.
● If you are towing a trailer, unhitch it from
your v
ehicle.
● Have the vehicle tool kit* ›››
page 47 and
the spare wheel ›››
page 75 ready.
● Observe the applicable legislation for each
countr
y (reflective vest, warning triangles,
etc.).
● All occupants should leave the vehicle and
wait in a s
afe place (for instance behind the
roadside crash barrier). WARNING
● Alw a
ys observe the above steps and pro-
tect yourself and other road users.
● If you change the wheel on a slope, block
the wheel on the oppo
site side of the car with
a stone or similar to prevent the vehicle from
moving. 45

or vehicles with Start-Stop system: con-
nect one end of
the black jump lead X to a
s uit
ab
le ground terminal, to a solid piece of
metal in the engine block, or to the engine
block itself ››› Fig. 70.
5. Connect the other end of the black
jump
lead X to a solid metal component bolted
t o the en
gine b
lock or to the engine block
itself of the vehicle with the flat battery.
Do not connect it to a point near the bat-
tery A .
6. Position the leads in such a way that they cannot
c
ome into contact with any moving
parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the boostin
g battery and let it run at idling
speed. 8. Start the engine of the vehicle with the flat
batter
y and wait for 2 or 3 minutes until
the engine is running.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped be
am headlights if they are
switched on.
10.Turn on the heater blower and heated rear window in the
vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11.When the engine is running, disconnect the lea
ds in reverse order to the details
given above.
Make sure the battery clamps have sufficient
metal-to-metal contact with the battery termi-
nals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about a minute. WARNING
● Ple a
se note the safety warnings referring to
working in the engine compartment
››› page 198, Working in the engine
compartment.
● The battery providing assistance must have
the same v
oltage as the flat battery (12 V)
and approximately the same capacity (see imprint on battery). Failure to comply could
re
s
ult in an explosion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Do not attach the negative cable from the
other vehic
le to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. » 53

Changing bulbs
Gener a
l
notesRead the additional information carefully
› ›

page 45
Before changing any bulb, first turn off the
failed device.
Do not touch the glass part of the bulb with
your bare hands. The fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, reducing bulb life and
causing condensation on the reflector sur-
face, thus reducing effectiveness. A bulb must only be replaced by one of the
same type. The type i
s indicated on the bulb,
either on the glass part or on the base.
Xenon headlights
With this type of headlight, the user can re-
place the turn signal bulb. Replacement of
the dipped/main beam bulb must be done by
Technical Services, given that complex ele-
ments must be removed from the vehicle and
the automatic control system that incorpo-
rates it must be reset.
The Xenon bulbs discharge 2.5 times the
light flux and have an average lifespan of 5
times more than that of halogen bulbs, this
means that, except due to unusual circum-
stances, there is no need to change the bulbs
for the whole life of the vehicle. WARNING
● Tak e p
articular care when working on com-
ponents in the engine compartment if the en-
gine is warm, there is a risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● The high voltage element of gas discharge
bul
bs* (xenon light) must be handled correct-
ly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not
to injure
yourself on sharp parts in the head-
light housing. CAUTION
● Remo v
e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights or parking lights be-
fore
you change a bulb. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u
sed bulbs in the proper manner. Note
● Dependin g on w
eather conditions (cold or
wet), the front lights, the fog lights, the tail
lights and the turn signals may be temporari-
ly misted. This has no influence on the useful
life of the lighting system. By switching on
the lights, the area through which the beam
of light is projected will quickly be demisted.
However, the edges may continue to be mis-
ted.
● Please check at regular intervals that all
lighting (es
pecially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
have the c
orrect new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead. The residue left by the fingerprints » 83

The legal requirements regarding the use of
vehicle lights in each country must be ob-
served.
The driver is personally responsible for the
correct use and adjustment of the lights in all
situations. WARNING
Never drive with just the side lights on, there
is a ri
sk of accident. The side lights are not
bright enough to illuminate the road ahead
and to ensure that other road users are able
to see you. Always use your dipped beam
headlights if it is dark or if visibility is poor. Note
● The dipped be am he
adlights will only work
with the ignition on. The side lights come on
automatically when the ignition is turned off.
● If the lights are left on after the key has
been taken out
of the ignition lock, an audi-
ble warning sounds while the driver door re-
mains open. This is a reminder to switch the
lights off.
● The rear fog light can dazzle drivers behind
you. Y
ou should use the rear fog light only
when visibility is very poor. For this reason,
when you exceed approximately 60 km/h (38 » 117
