lace as far away from traffic as
possible. ●

● If you are towing a trailer, unhitch it from
your v
ehicle.
● Have the vehicle tool kit* ›››

and the spare wheel ›››
page 218 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. 44
The essentials
Starting
7. Start the engine of the vehicle with the boo s
tin
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 1 minute. WARNING
● Ple a
se note the safety warnings referring to
working in the engine compartment
››› page 203.
● The battery providing assistance must have
the same v
oltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result 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. ●
Po s
ition the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
er wi
se electricity could flow as soon as the
positive terminals are connected. Changing the windscreen wiper

Fuses and bulbs
●
Prot ect
the fuse boxes when open to pre-
vent the entry of dust or humidity as they can
damage the electrical system.
● Always carefully remove the fuse box cov-
ers and r
efit them correctly to avoid problems
with your vehicle. Note
● One c omponent m
ay have more than one
fuse.
● Several components may run on a single
fuse.
● In the
vehicle, there are more fuses than
those indicat
ed in this chapter. These should
only be changed by a specialised workshop.
● Positions not containing a fuse do not ap-
pear in the fo
llowing tables.
● Some of the equipment listed in the tables
below pert
ain only to certain versions of the
model or are optional extras.
● Please note that the above lists, while cor-
rect at

change. Fuses in the dash panel

l
l-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to
an authorised workshop to have it replaced.
Double headlight bulb change
Changing bulbs requires a certain degree of
practical skill. If in doubt, we recommend you
have defective bulbs changed by a special-
ised service or, in case of an emergency,
seek professional assistance.
● Switch off the ignition and all of the lights
before c
hanging a bulb.
● Do not touch the glass part of the bulb with
your bar
e 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.
● There is a storage area for the bulb box in
the spar
e wheel well or below the carpet in
the luggage compartment. WARNING
● Tak e p
articular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● 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 and the parking light
before c
hanging 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 rear
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. ●
Ple a
se check at regular intervals that all
lighting (especially 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. Otherwise, the fingerprints left on
the glass will vaporise as a result of the heat
generated by the bulb, they will be deposited
on the reflector and damage its surface. Double headlight bulbs
