vehicle, LEDs may be used for
part or all of the interior and/or exterior light-

that of the vehicle. If an LED light fails, go to
an authorised workshop for its replacement.

at to do first ●
Park the vehicle on a horizontal surface
and in a s af
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 ge
arbox: Move the selector lever
to position P.
● If you are towing a trailer, unhitch it from
your v
ehicle.
● Have the vehicle tool kit ›››

 page 95
and the spare wheel* ready
›››  page 286.
● 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. 64

is not running, the gearbox oil pump does
not w
ork
and the gearbox is not adequately
lubricated for higher speeds or longer distan-
ces.
If the vehicle has to be towed with a break-
down truck, it must only be suspended at the
front wheels. Reason: the drive shafts are lo-
cated on the front wheels. If the car is towed
with the rear wheels lifted off the road (I.e.
travelling backwards), the drive shafts also
turn backwards. The planetary gears in the
automatic gearbox then turn at such high
speeds that the gearbox will be severely
damaged in a short time. Note
● If it i

s not possible to tow the vehicle in the
normal way, or if it has to be towed further
than 50 km (30 miles), it must be transported
on a special car transporter or trailer.
● Should the power supply to the selector
lever be int
errupted in position P, the selector
lever will be locked. Before the vehicle can be
recovered/manoeuvred you must manually
release the selector lever ›››

F u
se

s
Introduction In general, a fuse can be assigned to various
electric
al

components. Likewise, 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 special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
give seriou s

electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion syst
em.
● Take care not to cause short circuits in the
electrica
l system. WARNING
Using unsuitable fuses, repairing fuses or
bridging a c urr

ent circuit without fuses can
cause a fire and serious injury. ●
Never u se a f

use with a higher value. Only
replace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or simil
ar. CAUTION
● To pr ev

ent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● 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 pre-
vent the entr
y of dust or humidity as they can
damage the electrical system. Note
● One component m

ay have more than one
fuse.
● Several components may run on a single
fuse. 101

CAUTION
● Alw a

ys carefully remove the fuse box cov-
ers 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 humid-
ity inside fuse boxes can cause damage to
the electrical system. Note
● In the v ehic

le, there are more fuses than
those indicated 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.

Towing bracket device
WARNING
The towing bracket ball coupling must be
st or
ed securely in the luggage compartment
to prevent them being flung through the vehi-
cle and causing injury. Note
● By l

aw, the ball coupling must be removed
if a trailer is not being towed if it obscures
the number plate. Driving with a trailer
Fig. 244
Turn the 13-pin connector. Before driving
●
Grip the 13-pin connector at area A and
r emo
v

e it in the direction of the arrow
››› Fig. 244.
● Remove the protective cover 5

ards.
After driving
● Grip the 13-pin connector at area A and
in ser
t

it in the opposite direction to the arrow
››› Fig. 244.
● Fit the protective cover 5
› ›
› Fig. 232
on
the ball coupling.
Safety lug
The safety lug B
› ›
› Fig. 244
is used to hook
up the trailer's retainer cable.
On hooking it up to the safety lug, the retain-
er cable should have slack in all the trailer
positions with respect to the vehicle (sharp
bends, reverse gear, etc.).
Headlights
The front part of the vehicle may be raised
when the trailer is connected and the light
may dazzle the rest of the traffic.
Adapt the height of the headlights using the
headlight range rotary adjuster 1)
. WARNING
● Never u se the s

afety lug to tow!
● Adjust your speed to suit the road and traf-
fic condition
s.
● All work on the electrical system must be
carried out on
ly by specialised workshops.
● Never connect the trailer's electric system
to the electric
al connections of the rear lights
or any other power sources.
● After hooking up the trailer and connecting
the socket, c
heck that all the trailer's rear
lights are working properly. Note
● If ther e i

s any fault in the trailer's lighting,
check the fuses in the instrument panel fuse
box ›››
 page 63.
● The contact between the retainer cable and
the safety
lug may give rise to mechanical
wear in the lug's surface protection. This
wear will not prevent the safety lug from op-
erating properly or cause any fault and is ex-
cluded from the warranty.
● When connecting and disconnecting the
trail
er, the towing vehicle's handbrake
should be applied.
● When the tow hitch ball has not been fitted,
the socket
should remain concealed in its
housing on the bumper. 1)
This does not apply for vehicles with bi-xenon
hea dlights.
