Bodywork maintenance
BODyWORk MAIntenAnCe (1/2)
you should
Wash your car frequently, with the
engine off, with cleaning products rec-
ommended by the manufacturer (never
use abrasive products). Rinse thor -
oughly beforehand with a jet:
– spots of tree resin and industrial
grime;
– mud in the wheel arches and under -
neath the body which forms damp
patches;
– bird droppings , which cause a
chemical reaction with the paint that
rapidly discolours paintwork and
may even cause the paint to peel
off;
wash the vehicle immediately to
remove these marks since it is im -
possible to remove them by polish -
ing;
– salt, particularly in the wheel arches
and underneath the body after driv -
ing in areas where the roads have
been gritted.
Remove any plant matter (resin, leaves,
etc.) from the vehicle regularly.
What you should not doDo not degrease or clean mechani -
cal components (e.g. the engine com -
partment), underneath the body, parts
with hinges (e.g. inside the doors) and
painted plastic external fittings (e.g.
bumpers) using high-pressure clean -
ing equipment or by spraying on prod-
ucts not approved by our Technical
Department. Doing this could give rise
to corrosion or operational faults.
Wash the vehicle in bright sunlight or
freezing temperatures.
Do not scrape off mud or dirt without
pre-wetting.
Allow dirt to accumulate on the exterior.
Allow rust to form following minor im -
pacts.
Do not use solvents not approved by
our Technical Department to remove
stains as this could damage the paint-
work.
Do not drive in snow or muddy condi -
tions without washing the vehicle, par-
ticularly under the wheel arches and
body.
A well-maintained vehicle will last
longer. It is therefore recommended to
maintain the exterior of the vehicle reg-
ularly.
Your vehicle has been treated with very
effective anti-corrosion products. It is
nevertheless subject to various outside
influences.
Corrosive agents in the atmosphere
–
atmospheric pollution (built-up and
industrial areas),
– saline atmospheres (near the sea,
particularly in hot weather),
– seasonal and damp weather condi -
tions (e.g. road salt in winter, water
from road cleaners, etc.).
Minor impacts
Abrasive action
Dust and sand in the air, mud, road grit
thrown up by other vehicles, etc.
You should take a number of minor pre-
cautions in order to safeguard your ve-
hicle against such risks.

– connect end piece 9 to one of the ve-
hicle’s accessories sockets (refer to
the information on the “Accessories
socket” in Section 3) then press
switch 7 to inflate the tyre to the rec-
ommended pressure (refer to the
label located on the edge of the driv-
er’s door);
– after a maximum of 5 minutes, stop
inflating and read the pressure on
pressure gauge 6 . To adjust the
pressure if necessary: continue in -
flating to increase the pressure or
press button 5 to decrease it. If a minimum pressure of 1.8 bar is
not reached after 15 minutes, repair
is not possible; do not drive the ve-
hicle but contact an approved dealer.
Before using this kit, park
the vehicle at a sufficient
distance from traffic, switch
on the hazard warning

XenOn HeADLIGHtS: changing bulbs
Because some components (the bat -
tery, its mounting) need to be removed,
you are advised to have your bulbs
replaced by an approved dealer.
A special mounting is re -
quired to fit this type of
headlight, it is forbidden to
fit a headlight with xenon
bulbs to a vehicle which was not
designed for it.
Due to the danger involved
in handling high-voltage de-
vices, this type of bulb must
be replaced by an approved
dealer.The engine may be hot
during operations in close
proximity. In addition, the
engine cooling fan may
start at any moment.

connecting a battery charger
t he battery charger must be com -
patible with a battery with nominal
voltage of 12 volts.
Follow the instructions given by the
manufacturer of the battery charger
you are using.
t o avoid all risk of sparks:
Do not place metal objects on the bat-
tery as this could create a short circuit
between the terminals.
Battery
Never disconnect it.
Battery
BA tter Y: breakdown recovery (1/2)
Handle the battery with care
as it contains sulphuric acid,
which must not come into
contact with eyes or skin. If
it does, wash the affected area with
plenty of cold water.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion.
The engine may be hot when car -
rying out operations in close prox -
imity. In addition, the engine cooling
fan can come on at any moment.
Risk of injury.
Starting the vehicle using the
battery from another vehicle
If you have to use the battery from an-
other vehicle to start, obtain suitable
jump leads (with a large cross section)
from an approved dealer or, if you al -
ready have jump leads, ensure that
they are in perfect condition.
the two batteries must have an iden-
tical nominal voltage of 12 volts. The
battery supplying the current should
have a capacity (amp-hours, Ah) which
is at least the same as that of the dis-
charged battery.
Special procedures may be
required to charge some
batteries. Contact an ap -
proved Dealer.
Avoid all risk of sparks which may
cause an immediate explosion, and
charge the battery in a well-venti -
lated area.
Risk of serious injury.
Deactivate the Stop and
Start function for any opera -
tion performed in the engine
compartment.

replacing windscreen wiper
blades 1
With the ignition on and engine
switched off, lower the windscreen
wiper stalk completely: they stop
slightly away from the bonnet.
Lift wiper arm 3 , pull tab 2 (move -
ment A) and push the blade upwards.
t o refit
Slide the blade along the arm until it
clips on. Make sure that the blade is
correctly locked in position. Return the
windscreen wiper stalk to the park po-
sition.– In frosty weather, make
sure that the wiper blades
are not stuck by ice (to
avoid the risk of the motor
overheating).
– Check the condition of the wiper
blades.
Replace the wiper blades as soon
as they begin to lose efficiency
(approximately once a year).
Whilst changing the blade, take care
not to drop the arm onto the window
after it has been removed as this
may break the window.

Check the condition of the wiper
blades. You are responsible for their
service life:
– clean the blades and the wind -
screen regularly with soapy
water;
– do not use them when the wind -
screen is dry;
– free them from the windscreen
when they have not been used
for a long time.
