STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
Park your vehicle in a covered, dry and
possibly airy location the windows open
slightly.
Check that the Electric Park Brake is not
engaged.
Disconnect the negative (-) terminal from
the battery post and be sure that the
battery is fully charged. During storage
check battery charge quarterly.
If you do not disconnect the battery from
the electrical system, check the battery
charge every 30 days.
Clean and protect the painted parts by
applying protective waxes.
Clean and protect polished metal parts by
applying protective waxes.
Apply talcum powder to the front and rear
wiper blades and leave raised from the
glass.
Cover the vehicle with an appropriate
cover taking care not to damage the
painted surface by dragging across dirty
surfaces. Do not use plastic sheeting
which will not allow the evaporation of
moisture present on the surface of the
vehicle.
Inflate the tires at a pressure of +7.25 psi
(+0.5 bar) higher than recommended on
the tire placard and check it periodically.
Do not drain the engine cooling system.
Whenever you leave the vehicle stationary
for two weeks or more, idle the engine for
approximately five minutes, with the air
conditioning system on and high fan
speed. This will ensure proper lubrication
of the system, thus minimizing the possi -
bility of damage to the compressor when
the vehicle is put back into operation.
CAUTION!
Proper operation of four-wheel drive
vehicles depends on tires of equal size,
type and circumference on each wheel.
Any difference in tire size can cause
damage to the power transfer unit. Tire
rotation schedule should be followed to
balance tire wear.

NOTE:
When the vehicle has not been started or driven
for at least 30 days, an Extended Park Start
Procedure is required to start the vehicle.
Refer to “Starting The Engine” in “Starting
And Operating” for further information.
BODYWORK
Preserving The Bodywork
Washing
Wash your vehicle regularly. Always wash
your vehicle in the shade using a mild car
wash soap, and rinse the panels
completely with clear water.
If insects, tar, or other similar deposits
have accumulated on your vehicle, use a
specific detergent to remove.
Use a high quality cleaner wax to remove
road film, stains and to protect your paint
finish. Take care never to scratch the
paint.
Avoid using abrasive compounds and
power buffing that may diminish the gloss
or thin out the paint finish.
Special Care
If you drive on salted or dusty roads or if
you drive near the ocean, hose off the
undercarriage at least once a month.
It is important that the drain holes in the
lower edges of the doors, rocker panels,
and trunk be kept clear and open.
If you detect any stone chips or scratches
in the paint, touch them up immediately.
The cost of such repairs is considered the
responsibility of the owner.
If your vehicle is damaged due to a colli-
sion or similar cause that destroys the
paint and protective coating, have your
vehicle repaired as soon as possible. The
cost of such repairs is considered the
responsibility of the owner.
If you carry special cargo such as chemi -
cals, fertilizers, de-icer salt, etc., be sure
that such materials are well packaged and
sealed.
If a lot of driving is done on gravel roads,
consider mud or stone shields behind
each wheel.
Touch up the scratches as soon as
possible. An authorized dealer has touch
up paint to match the color of your vehicle.
Some parts of the vehicle may be painted
with a matte paintwork which requires
special care for its preservation
CAUTION!
Before removal of the positive and
negative terminals to the battery, wait at
least a minute with ignition switch in the
OFF position and close the driver’s door.
When reconnecting the positive and
negative terminals to the battery be sure
the ignition switch is in the OFF position
and the driver’s door is closed. CAUTION!
Do not use abrasive or strong cleaning
materials such as steel wool or scouring
powder that will scratch metal and
painted surfaces.
Use of power washers exceeding 1,200
psi (8,274 kPa) can result in damage or
removal of paint and decals.

FUEL REQUIREMENTS —
GASOLINE ENGINE
1.4L Turbo Gasoline Engine
This engine is designed to meet all emission
regulations and provide satisfactory fuel
economy and performance when using
high-quality unleaded gasoline having a
minimum research octane rating (RON) of
95. For optimum performance and fuel
economy the use of minimum research
octane rating (RON) of 98 or higher is recom-
mended. Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita
-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita -
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
Ethanol
The manufacturer recommends that your
vehicle be operated on fuel containing no
more than 10% ethanol. Purchasing your
fuel from a reputable supplier may reduce
the risk of exceeding this 10% limit and/or of
receiving fuel with abnormal properties.
Materials Added To Fuel
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish
removal may contain active solvents or
similar ingredients. These can harm fuel
system gasket and diaphragm materials.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline
with oxygenates such as ethanol.
CAUTION!
Do not load your vehicle any heavier than
the GVWR or the maximum front and rear
GAWR. If you do, parts on your vehicle can
break, or it can change the way your
vehicle handles. This could cause you to
lose control. Also overloading can shorten
the life of your vehicle. Never exceed the
maximum combined vehicle load value:
the maximum towable load is only allowed
if it does not exceed the maximum
combined vehicle load.
CAUTION!
Use of fuel with Ethanol content higher
than 10% may result in engine
malfunction, starting and operating
difficulties, and materials degradation.
These adverse effects could result in
permanent damage to your vehicle.
CAUTION!
DO NOT use E-85, gasoline containing
methanol, or gasoline containing more
than 15% ethanol (E-15). Use of these
blends may result in starting and
drivability problems, damage critical fuel
system components, cause emissions to
exceed the applicable standard, and/or
cause the Malfunction Indicator Light to
illuminate. Please observe pump labels as
they should clearly communicate if a fuel
contains greater than 15% ethanol (E-15).

Fuel System CautionsNOTE:
Intentional tampering with the emissions
control system can result in civil penalties
being assessed against you.
Carbon Monoxide Warnings
FUEL REQUIREMENTS —
DIESEL ENGINE
Diesel Engine
Use good quality diesel fuel from a reputable
supplier. If the outside temperature is very
low, the diesel fuel thickens due to the
formation of paraffin clots with consequent
defective operation of the fuel supply
system.
In order to avoid these problems different
types of fuel are distributed according to the
season: summer type, winter type and arctic
type (cold/mountain areas). If fueling with
diesel fuel whose features are not suitable
for the temperature of use, it is advisable to
mix in a suitable additive with the fuel. With
the proportions shown on the container, pour
the additive in the tank before fueling.
When using or parking the vehicle for a long
time in the mountains or cold areas, it is
advisable to refuel using locally available
fuel. In this case, it is also advisable to keep
the tank over half full.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited
by law. Using leaded gasoline can impair
engine performance and damage the
emissions control system.
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the
catalytic converter to overheat. If you
notice a pungent burning odor or some
light smoke, your engine may be out of
tune or malfunctioning and may require
immediate service. Contact an autho-
rized dealer for service assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of meth-
anol. Fuel system damage or vehicle
performance problems resulting from the
use of such fuels or additives is not the
responsibility of the manufacturer and
may void or not be covered under the
New Vehicle Limited Warranty.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They
contain carbon monoxide, a colorless
and odorless gas, which can kill. Never
run the engine in a closed area, such as
a garage, and never sit in a parked
vehicle with the engine running for an
extended period. If the vehicle is
stopped in an open area with the engine
running for more than a short period,
adjust the ventilation system to force
fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle
is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive
with all side windows fully open.
