WARNING!
work for which you have the knowledge
and the proper equipment. If you have any
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield 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 prod-
ucts such as engine oil, gasoline, etc.NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.
The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following
points:
• Wear or uneven edges
• Foreign material
• Hardening or cracking
• Deformation or fatigue
If a wiper blade or wiper arm is damaged,
replace the affected wiper arm or blade with
a new unit. Do not attempt to repair a wiper
arm or blade that is damaged.
Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back
against the glass without the wiper blade
in place or the glass may be damaged.
1. Lift the wiper arm to raise the wiper blade
off of the glass, until the wiper arm is in
the full up position.

Installing The Rear Wiper
1. Lift the wiper arm off of the glass.
2. Insert the wiper blade pivot pin into the
opening on the end of the wiper arm and
rotate the wiper in to place.
3. Place with wiper on the glass and close
the tail gate.
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.
WARNING!
• When working near the radiator cooling
fan, 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 the engine and, intercooler (if
equipped) coolant (antifreeze) protection ev-
ery 12 months (before the onset of freezing
weather, where applicable). If the engine
and, intercooler (if equipped) is dirty or rusty
in appearance, the system should be drained,
flushed and refilled with fresh OAT coolant
(conforming to MS.90032) by an authorized
dealer. Check the front of the A/C condenser
(if equipped) or radiator for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the A/C condenser (if
equipped) or the back of the radiator core.
Check the engine and, intercooler (if
equipped) cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness ofthe connection at the coolant recovery bottle
and radiator. Inspect the entire system for
leaks. DO NOT REMOVE THE COOLANT
PRESSURE CAP WHEN THE COOLING SYS-
TEM IS HOT.
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

VEHICLE IDENTIFICATION
NUMBER
The Vehicle Identification Number (VIN) is
found on the left front corner of the A pillar,
visible from outside of the vehicle through
the windshield. This number also appears
underbody, on the right side of the frame rail
near the center of the vehicle, as well as on
the Automobile Information Disclosure Label
affixed to a window on your vehicle. Save this
label for a convenient record of your vehicle
identification number and optional equip-
ment.
The VIN is also stamped on either right or left
hand side of the engine block.NOTE:
It is illegal to remove or alter the VIN plate.
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 lugnuts/bolts should be torqued using a properly
calibrated torque wrench using a high quality
six sided (hex) deep wall socket.

FUEL REQUIREMENTS —
GASOLINE ENGINE
2.0L Engine
This engine is designed to meet all emission
regulations, and provide satisfactory fuel
economy and performance when using high-
quality unleaded gasoline with a recom-
mended RON of 97.While operating on gasoline with the required
octane number, hearing a light knocking
sound from the engine is not a cause for
concern. However, if the engine is heard
making a heavy knocking sound, see your
dealer immediately. Use of gasoline with a
lower than recommended octane number can
cause engine failure and may void or not be
covered by the New Vehicle Limited War-
ranty.
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.
3.6L Engine
These engines are designed to meet all emis-
sions regulations and provide excellent fuel
economy and performance when using high-
quality unleaded gasoline with a minimum
Research Octane Number (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.

FUEL REQUIREMENTS —
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 for-
mation of paraffin clots with consequent de-
fective 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 isadvisable to refuel using locally available
fuel. In this case, it is also advisable to keep
the tank over half full.
This vehicle must only use premium diesel
fuel that meets the requirements of EN 590.
Biodiesel blends up to 7% that meet EN
590 may also be used.
WARNING!
Do not use alcohol or gasoline as a fuel-
blending agent. They can be unstable un-
der certain conditions and hazardous or
explosive when mixed with diesel fuel.
CAUTION!
The manufacturer requires that you must
fuel this vehicle with Ultra Low Sulfur
CAUTION!
Highway Diesel fuel (15 ppm Sulfur maxi-
mum) and prohibits the use of Low Sulfur
Highway Diesel fuel.
Diesel fuel is seldom completely free of wa-
ter. To prevent fuel system trouble, drain the
accumulated water from the fuel/water sepa-
rator using the provided fuel/water separator
drain. If you buy good quality fuel and follow
the cold weather advice above, fuel condi-
tioners should not be required in your vehicle.
If available in your area, a high cetane “pre-
mium” diesel fuel may offer improved cold-
starting and warm-up performance.
