Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and odor-
less. Breathing it can make you unconscious and
can eventually poison you. To avoid breathing
(CO), follow these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move
your vehicle in or out of the area.
• If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all win-
dows are closed and the climate control BLOWER
switch is set at high speed. DO NOT use the
recirculation mode.
• If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set
the blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine ex-
haust system. Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be detected
inside the vehicle, or when the underside or rear of the
vehicle is damaged, have a competent mechanic inspect
the complete exhaust system and adjacent body areas
for broken, damaged, deteriorated, or mispositioned
parts. Open seams or loose connections could permit
exhaust fumes to seep into the passenger compartment.
In addition, inspect the exhaust system each time the
vehicle is raised for lubrication or oil change. Replace as
required.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for
cuts, frays, and loose parts. Damaged parts must be
replaced immediately. Do not disassemble or modify
the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced
after a collision if they have been damaged (i.e., bent
retractor, torn webbing, etc.). If there is any question
regarding seat belt or retractor condition, replace the
seat belt.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

Instrument Cluster Descriptions
1. Speedometer•Indicates vehicle speed.
2. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN posi-
tion.
•
The fuel pump symbol points to the side of
the vehicle where the fuel door is located.
3. Temperature Gauge
•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range
indicates that the engine cooling system is operat-
ing satisfactorily.
• The gauge pointer will likely indicate a higher
temperature when driving in hot weather or up
mountain grades. It should not be allowed to
exceed the upper limits of the normal operating
range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide
to look under the hood yourself, see “Maintaining
Your Vehicle”. Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge
reads “H” pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until the
pointer drops back into the normal range. If the
pointer remains on the “H”, turn the engine off
immediately and call an authorized dealer for ser-
vice.

CAUTION!
Failure to follow these cautions can cause damage
to the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft
cloth and a mild washing solution, wiping paral-
lel to the heating elements. Labels can be peeled
off after soaking with warm water.
• Do not use scrapers, sharp instruments, or abra-
sive window cleaners on the interior surface of
the window.
• Keep all objects a safe distance from the window.
Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator
to manually activate or deactivate the air conditioning
system. When the air conditioning system is turned on,
cool dehumidified air will flow through the outlets into
the cabin. For improved fuel economy, push the A/C
button to turn off the air conditioning and manually
adjust the blower and airflow mode settings. Also,
make sure to select only Panel, Bi-Level or Floor modes. NOTE:
•
If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed if
needed.
• If your air conditioning performance seems lower
than expected, check the front of the A/C condenser
(located in front of the radiator), for an accumulation
of dirt or insects. Clean with a gentle water spray
from the front of the radiator and through the
condenser.
Recirculation
When outside air contains smoke, odors, or high hu-
midity, or if rapid cooling is desired, you may wish to
recirculate interior air by pushing the Recirculation
control button. The recirculation indicator will illumi-
nate when this button is selected. Push the button a
second time to turn off the Recirculation mode and
allow outside air into the vehicle.

UNDERSTANDING YOUR INSTRUMENT PANEL 203

NOTE:The system will not automatically sense the
presence of fog, mist or ice on the windshield. DE-
FROST mode must be manually selected to clear the
windshield and side glass.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is func-
tioning properly and the proper amount, type, and
concentration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes, in fresh air
with the blower setting on high. This will ensure ad-
equate system lubrication to minimize the possibility of
compressor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower
speed. Do not use the Recirculation mode without A/C
for long periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves.
Leaves collected in the air intake may reduce airflow,
and if they enter the plenum, they could plug the water
drains. In winter months, make sure the air intake is
clear of ice, slush, and snow.
A/C Air Filter
The climate control system filters out dust and pollen
from the air. Contact your authorized dealer to service
your A/C air filter, and to have it replaced when needed.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel below the radio.Push the switch to turn on the Hazard Warning
flashers. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncom-
ing traffic of an emergency. Push the switch a second
time to turn off the Hazard Warning flashers.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is
disabled and it is creating a safety hazard for other
motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flashers will continue to operate with
the ignition key removed and the vehicle locked.
NOTE: With extended use, the Hazard Warning flash-
ers may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate
action.
• On the highways — slow down. •
In city traffic — while stopped, place the transmis-
sion in NEUTRAL, but do not increase engine idle
speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling system
and turning the A/C off can help remove this heat.
• You can also turn the temperature control to maxi-
mum heat, the mode control to floor and the blower
control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the 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 try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
274 WHAT TO DO IN EMERGENCIES

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the pointer rises to the H (red) mark,
the instrument cluster will sound a chime. When
safe, pull over and stop the vehicle with the engine
at idle. Turn off the air conditioning and wait until
the pointer drops back into the normal range. If the
pointer remains on the H (red) mark for more than
a minute, turn the engine off immediately and call
for service.
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

you see or hear steam coming from under the
hood, do not open the hood until the radiator has
had time to cool. Never try to open a cooling
system pressure cap when the radiator is hot.
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 appearance, 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.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add
coolant properly. Failure to fill these systems properly
could lead to severe internal engine damage. If any
coolant is needed to be added to the system, please
contact your local authorized dealer.
314 MAINTAINING YOUR VEHICLE

If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (antifreeze) (conforming to
MS.90032).
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT)
engine coolant (antifreeze), may result in engine
damage and may decrease corrosion protection.
Organic Additive Technology (OAT) engine cool-
ant is different and should not be mixed with
Hybrid Organic Additive Technology (HOAT)
engine coolant (antifreeze) or any “globally com-
patible” coolant (antifreeze). If a non-OAT engine
coolant (antifreeze) is introduced into the cooling
system in an emergency, the cooling system will

CAUTION! (Continued)
need to be drained, flushed, and refilled with
fresh OAT coolant (conforming to MS.90032), by
an authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the engine coolant
and may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (anti-
freeze). Use of propylene glycol-based engine
coolant (antifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that
allows extended maintenance intervals. This engine
coolant (antifreeze) can be used up to ten years or
150,000 miles (240,000 km) before replacement. To pre-
vent reducing this extended maintenance period, it is
important that you use the same engine coolant (OAT
coolant conforming to MS.90032) throughout the life of
your vehicle.
