WARNING!
• When replacing a blown fuse, always use
an appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a
blown fuse with metal wires or any other
material. Do not place a fuse inside a
circuit breaker cavity or vice versa. Fail-
ure to use proper fuses may result in
serious personal injury, fire and/or prop-
erty damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
• If the replaced fuse blows again, contact
an authorized dealer.
• If a general protection fuse for safety
systems (air bag system, braking sys-
WARNING!
tem), power unit systems (engine sys-
tem, transmission system) or steering
system blows, contact an authorized
dealer.
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check
the fuse element inside the blade fuse for a
break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery dis-
charge.
Fuse Location
The fuses are grouped into controllers lo-
cated in the engine compartment.
IN CASE OF EMERGENCY

SCHEDULED SERVICING
1.4L Gasoline Engine
The scheduled services listed in this manual
must be done at the times or mileages speci-
fied to protect your vehicle warranty and
ensure the best vehicle performance and re-
liability. More frequent maintenance may be
needed for vehicles in severe operating con-
ditions, such as dusty areas and very short
trip driving. Inspection and service should
also be done anytime a malfunction is sus-
pected.
• Change your engine oil more often if you
drive your vehicle off-road for an extended
period of time.
• Under no circumstances should oil change
intervals exceed 7,500 miles (12,000 km)
or 12 months, whichever comes first.Once A Month Or Before A Long Trip
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Check the fluid levels of the coolant reser-
voir and brake master cylinder, fill as
needed.
• Check function of all interior and exterior
lights.
At Each Oil Change
• Change oil and filter.
• Rotate the tires.Rotate at the first sign of
irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten ter-
minals as required.• Inspect brake pads, shoes, rotors, drums,
hoses and park brake.
• Inspect engine cooling system protection
and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty
or off-road conditions.
Refer to the “Maintenance Plan” on the fol-
lowing page for the required maintenance
intervals.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.

Once A Month Or Before A Long Trip
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Check the fluid levels of the coolant reser-
voir and brake master cylinder, fill as
needed.
• Check function of all interior and exterior
lights.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
• Inspect for the presence of water in the fuel
filter/water separator unit.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.
227

WARNING!
• When working near the radiator cooling
fan, disconnect the fan motor lead or
turn the ignition to the OFF mode. The
fan is temperature controlled and can
start at any time the ignition is in the ON
mode.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine
coolant (antifreeze) is dirty or rusty in appear-
ance, the system should be drained, flushed
and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser
for any accumulation of bugs, leaves, etc. If
dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood ser-
vices or immediately if the “Brake Warning
Light” is illuminated.
Be sure to clean the top of the master cylin-
der area before removing the cap. If neces-
sary, add fluid to bring the fluid level up to
the requirements described on the brakefluid reservoir. With disc brakes, fluid level
can be expected to fall as the brake pads
wear. Brake fluid level should be checked
when pads are replaced. However, low fluid
level may be caused by a leak and a checkup
may be needed.
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubricants”
in “Technical Specifications” for further
information.
WARNING!
• Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its per-
formance. The proper type of brake fluid
for your vehicle is also identified on the
original factory installed hydraulic mas-
ter cylinder reservoir.
• To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
SERVICING AND MAINTENANCE

CAUTION!
Proper operation of four-wheel drive ve-
hicles 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.
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 bat-
tery 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 sur-
face 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 is station-
ary for two weeks or more, run idle the
engine for approximately five minutes, withthe air conditioning system on and high fan
speed. This will ensure a proper lubrication
of the system, thus minimizing the possi-
bility of damage to the compressor when
the vehicle is put back into operation.
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 ve-
hicle. Refer to “Starting The Engine” in
“Starting And Operating” for further
information.
CAUTION!
Before removal of the positive and nega-
tive 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 ter-
minals to the battery be sure the ignition
switch is in the OFF position and the
driver’s door is closed.SERVICING AND MAINTENANCE
