The suggested Front Wheel Drive (FWD) Tire
rotation method is the “forward cross” shown
in the following diagram. This rotation
pattern does not apply to some directional
tires that must not be reversed.Tire Rotation (Forward Cross)
The suggested Four Wheel Drive (4WD) Tire
rotation method is the “rearward cross”
shown in the following diagram.

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.

IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is
found on the left front corner of the wind-
shield and is visible from the outside of the
vehicle. The VIN number also is stamped
into the right front body, on the front floor.
With the right front seat in the rear most
position, a door in the carpet can be opened
to reveal the VIN. It also appears on the Auto -
mobile Information Disclosure Label affixed
to a window on your vehicle, the vehicle
registration, and the title.

It is illegal to remove or alter the VIN.
WHEEL AND TIRE TORQUE
SPECIFICATIONS
Proper lug nut/bolt torque is very important
to ensure that the wheel is properly mounted
to the vehicle. Any time a wheel has been
removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a
properly calibrated torque wrench using a
high quality six sided (hex) deep wall socket.
Torque Specifications
**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion
or loose particles.

Tighten the lug nuts/bolts in a star pattern
until each nut/bolt has been tightened twice.
Ensure that the socket is fully engaged on
the lug nut/bolt (do not insert it halfway).
NOTE:
If in doubt about the correct tightness, have
them checked with a torque wrench by an
authorized dealer or service station.Torque PatternAfter 25 miles (40 km), check the lug nut/
bolt torque to be sure that all the lug nuts/
bolts are properly seated against the wheel.

WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts/bolts
fully until the vehicle has been lowered.
Failure to follow this warning may result in
personal injury.

Minimum Ground Clearance (Reference A)
The clearance value is measured next to the
lower edge of the differential. This value also
defines those for the “Approach Angle” the
“Departure Angle” and the “Breakover
Angle”.
Dimensions are expressed in inches (mm)
and refer to the vehicle equipped with its
original tires.Approach Angle (Reference B)
The approach angle is determined by the
horizontal line of the road surface, and by the
tangent line passing between the front
wheel, and the most projecting low point of
the car.
The wider the angle, the lower the chance to
hit an obstacle with the body or chassis,
when climbing a steep slope or overcoming
an obstacle.Departure Angle (Reference C)
The departure angle is determined by the
same lines of the “Approach Angle”, and
refers to the rear part of the vehicle.
Breakover Angle (Reference D)
The value of the “Breakover Angle” is linked
to the ground clearance of the vehicle and
indicates the attitude of the vehicle to over
-
come a wedge, more or less steep,

preventing the vehicle from resting on the
ground with the body or chassis after
touching the wedge with its lowest and most
projecting parts (usually the underbody),
because this would highly reduce wheel grip.
The wheels, without a suitable grip to the
ground, will not have sufficient hold to move
the vehicle, and will surge.
The higher the ground clearance, the wider
the breakover angle. Always bear in mind
that the higher the ground clearance, the
lower the stability, due to a higher center of
gravity which reduces the side rollover angle.Ground Clearance / Typical Angles
MeasurementsWHEELS
Refer to the tire placard label on the left side
B-pillar or rear edge of the passenger door of
the vehicle or to the Registration Document
for the tire size and pressure. Refer to
“Tires” in the “Servicing And Maintenance”
Chapter for further information.
NOTE:
If there are any discrepancies between the
Owner’s Manual and the Registration Docu -
ment, take the information from the Regis -
tration Document. For safe driving the
vehicle must be fitted with tires of the same
make and type on all wheels.
