FUSES
WARNING!
• When replacing a blown fuse, always usean 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.
WARNING!
• If a general protection fuse for safetysystems (air bag system, braking sys-
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.
Underhood Fuses
The Power Distribution Center is located in
the engine compartment near the battery.
This center contains cartridge fuses, mini-
fuses and relays. A label that identifies each
component is printed on the inside of the
cover.

SCHEDULED SERVICING
Scheduled Servicing — 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.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
An “Oil Change Required” will be displayed
in the instrument cluster and a single chime
will sound, indicating that an oil change is
necessary.
The oil change indicator message will illumi-
nate approximately 7,000 miles (11,200 km)
after the most recent oil change was per-
formed. Have your vehicle serviced as soon as
possible, within 500 miles (800 km).
NOTE:
• The oil change indicator message will notmonitor the time since the last oil change.
Change your vehicle’s oil if it has been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
• 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.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If this scheduled
oil change is performed by someone other
than your authorized dealer the message can
be reset by referring to the steps described
under ”Instrument Cluster Display” in “Get-
ting To Know Your Instrument Panel” for
further information. 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.
SERVICING AND MAINTENANCE
196

•Regardless of the distance covered, the tim-
ing and accessory belts must be changed
every 4 years for particularly demanding use
(cold climates, city driving, long periods of
idling) or at least every 6 years. Under no
circumstances should these intervals be
exceeded.
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.
201

Checking Oil Level
To assure proper engine lubrication, the en-
gine oil must be maintained at the correct
level. Check the oil level at regular intervals,
such as every fuel stop. The best time to
check the engine oil level is about five min-
utes after a fully warmed up engine is shut
off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings.
There are three possible dipstick types,
• Crosshatched zone.
• Crosshatched zone marked SAFE.
• Crosshatched zone marked with MIN at thelow end of the range and MAX at the high
end of the range.
NOTE:
Always maintain the oil level within the cross-
hatch markings on the dipstick.
Adding 1 quart (1.0 liters) of oil when the
reading is at the low end of the dipstick range
will raise the oil level to the high end of the
range marking.
CAUTION!
Overfilling or underfilling the crankcase
will cause aeration or loss of oil pressure.
This could damage your engine.
Cooling System
WARNING!
• You or others can be badly burned by hot engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator
or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling
fan, disconnect the fan motor lead or
turn the ignition to the OFF mode. The
WARNING!
fan is temperature controlled and can
start at any time the ignition is in the ON
mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty, the sys-
tem should be drained, flushed, and refilled
with fresh PARAFLU
UPFormula OAT (Or-
ganic Additive Technology) or equivalent
meeting the requirements of FCA Material
Standard MS.90032. by an authorized
dealer. 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.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the coolant
recovery bottle and radiator. Inspect the en-

tire system for leaks. DO NOT REMOVE THE
COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Adding Washer Fluid
The windshield and rear window washers
share the same fluid reservoir. The fluid res-
ervoir is located in the front of the engine
compartment. Be sure to check the fluid level
in the reservoir at regular intervals. Fill the
reservoir with windshield washer solvent (not
radiator antifreeze) and operate the system
for a few seconds to flush out the residual
water.
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this
will help blade performance.
To prevent freeze-up of your windshield
washer system in cold weather, select a solu-
tion or mixture that meets or exceeds the
temperature range of your climate. This rat-
ing information can be found on most washer
fluid containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised
when filling or working around the washer
solution.
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.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should
be checked whenever the vehicle is serviced,
or immediately if the brake system warning
light is on. If necessary, add fluid to bring
level within the designated marks on the side
of the reservoir of the brake master cylinder.
Be sure to clean the top of the master cylin-
der area before removing cap. 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. If the
brake fluid is abnormally low, check the sys-
tem for leaks.
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for further information.
WARNING!
• Use only manufacturer's recommendedbrake 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

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 re-
moved 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
Lug Nut/BoltTorque **Lug Nut/Bolt
Size Lug Nut/Bolt
Socket Size
100 Ft-Lbs (135 N·m) M12 x 1.25 19 mm
**Use only an authorized dealer recom-
mended 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).
After 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 fully
until the vehicle has been lowered. Failure
to follow this warning may result in per-
sonal injury.
FUEL REQUIREMENTS —
GASOLINE ENGINE
This engine is designed to meet all emissions
regulations and provide excellent fuel
economy and performance when using high
quality unleaded gasoline with a minimum
research octane rating (RON) of 91.
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.
