Wiper Maintenance and Blades
Replacement Windshield Wiper Arms Lifting
When the windshield wiper arms are
in rest position it is not possible to
check or replace the blades as they
remain under the engine hood.
To service the blades it is necessary to
move the wiper arms in “Service”
position (see chapter “Wipers and
Washers” in section “Understanding
the Vehicle”). In this way it is possible
to lift the arms for cleaning or
replacing the wiper blades.
WARNING!
It is dangerous to operate or service
the wiper blades with the windshield
wipers in an active position (any
position different from “OFF”) and
with the ignition switch in the RUN
position. The rain sensors may
suddenly activate the wipers. Always use the “Service” position for any
intervention on the windshield wiper
blades.
Windshield Wiper Maintenance
Life
expectancy of wiper
blades varies
depending on the geographical area’s
weather conditions where the car is
used and frequency of use. Poor
performance of blades may be present
with chattering, marks on the glass,
water lines or wet spots. If any of
these conditions are present, clean the
wiper blades or replace if necessary.
Clean the rubber edges of the wiper
blades and the windshield/rear
window glasses periodically with a
sponge or soft cloth and a mild
nonabrasive cleaner. This will remove
accumulations of salt or road film.
Operation of the wipers on dry glass
for long periods may cause
deterioration of the wiper blades.
Always use washer fluid when using
the wipers to remove salt or dirt from
a dry windshield.
Avoid using the wiper blades to
remove frost or ice from the
windshield. Keep the blade rubber out
of contact with petroleum products
such as engine oil, gasoline, etc.
Spray nozzles If the jet does not work, first check
that there is fluid in the tank (see
paragraph “Level checks” in this
section) then check that the nozzles
are not clogged.
Windshield Wiper Blades Replacement
• Move the wiper arms into “Service”
position, (see chapter “Windshield
Wipers and Washers” in section
“Understanding the Vehicle”) and lift
them.
• Press the indicated button, slip off
the blade support from the arm and
replace it.
• Return the blade to its original
position on the windshield.

Useful Advice to Extend
Battery Life When parking the vehicle, make sure
that the doors, hood, liftgate and flaps
are properly closed. All interior lights
should be off.
When the engine is turned off, do not
keep the connected devices switched
on for a long time (such as radio,
hazard warning flashers, fan, etc.).
CAUTION!
If the battery charge remains below
50% for a long period of time, it will
be damaged due to sulfation; its
performance and starting power will
be reduced and it will be more subject
to freezing. We recommend you to have the
battery
charge condition checked,
preferably
at the beginning of the cold
season, to prevent the electrolyte from
freezing.
This check should be carried out more
frequently if the vehicle is used mainly
for short trips or if it is equipped with
power-absorbing devices that remain
permanently on even when the
ignition switch is off. This applies
above all if these devices have been
retrofitted ("Aftermarket" services).
If the vehicle is not used for long
periods of time, please see “Vehicle
Stored for Long Periods” in this
section.
Battery Recharge WARNING!
The process of charging or recharging
the battery produces hydrogen, a
flammable gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all times.
• Before using a charger device always
check that this tool is suitable for the
installed battery, with constant
voltage (lower than 14.0 V) and low
