Useful Advice For Extending The Life Of
Your Battery
To avoid draining your battery and make it last
longer, observe the following instructions:
When you park the vehicle, ensure that the
doors and liftgate are closed properly to
prevent any lights from remaining on inside
the passenger's compartment.
Do not keep accessories (e.g. radio, hazard
warning lights, etc.) switched on for a long
time when the engine is not running.
Before performing any operation on the
electrical system, disconnect the negative
battery cable.
If you wish to install electrical accessories
after purchasing the vehicle that require
permanent electrical supply (e.g. alarm, etc.),
or accessories which influence the electrical
supply requirements, contact an authorized
dealer, who’s qualified staff will evaluate the
overall electrical consumption.
NOTE:

After the battery is disconnected, the steering
must be initialized. The warning light on the
instrument cluster display switches on to indi
-
cate this. To carry out this procedure, simply
turn the steering wheel all the way from one
end to the other, and then turn it back to the
central position.Battery
The battery does not require the electrolyte to
be topped up with distilled water. A periodic
check carried out at an authorized dealer,
however, is necessary to check efficiency.
Follow the battery manufacturer's instructions
for maintenance.
CAUTION!
If the charge level remains under 50% for a
long time, the battery may be damaged by
sulfation, reducing its capacity and
efficiency during the vehicle start. The
battery is also more prone to the risk of
freezing (at temperatures as high as 14°F
(-10°C).

Thoroughly clean the components, eliminating
every trace of dirt and dust. After lubricating,
eliminate excess oil and grease. Also pay
particular attention to the hood closing
devices, to ensure correct operation. Opera-
tions of the hood are to be carried out with the
engine cold. Remember to check, clean and
lubricate the locking, release and safety
devices.
Lubricate the external lock barrels twice a
year. Apply a small amount of high-quality
lubricant directly into the lock barrel.
If necessary, contact an authorized dealer as
soon as possible.
Windshield Wiper
Periodically clean the windshield, rear window
and rubber profile of the windshield wiper
blades, using a sponge or a soft cloth and a
non-abrasive detergent. This eliminates the
salt or impurities accumulated when driving.
Prolonged operation of the windshield window
wipers with dry glass may cause the deteriora -
tion of the blades, in addition to abrasion of
the surface of the glass. To eliminate the impu -
rities on the dry glass, always operate the
windshield washers.
In the event of very low outdoor temperatures,
below 0°F (-17.8°C), ensure that the move -
ment of the rubber part in contact with the
glass is not obstructed. Use a suitable deicing
product to release it if required. Avoid using the windshield wipers to remove
frost or ice.
Also avoid contact of the rubber profile of the
blades with petroleum derivatives such as
engine oil, gas, etc.

NOTE:

The life of the windshield wiper blades varies
according to the usage frequency. It is advised
to replace the blades approximately once a
year. When the blades are worn, noise, marks
on the glass or streaks of water may be
noticed. In the presence of these conditions,
clean the windshield wiper blades or, if neces
-
sary, replace them.
Raising The Windshield Wiper Blades
(“Service Position” Function)
The “service position” function allows the
driver to replace the windshield wiper blades
easily. It is also recommended to activate this
function when it is snowing and to make it
easier to remove any dirt deposits in the area
where the blades are normally positioned,
while washing.
