Downloaded from www.Manualslib.com manuals search engine When should an air bag inflate?
The air bag is designed to inflate in moderate to severe frontal or
near-frontal crashes. The air bag will inflate only if the impact speed
is
above the system’s designed “threshold level.” If your vehicle goes straight
into
a wall that doesn’t move or deform, the threshold level is about 14 to 18
mph (23 to 29 kdh). The threshold level can vary, however, with specific
vehicle design,
so that it can be somewhat above or below this range. If your
vehicle strikes something that will move or deform, such
as a parked car, the
threshold level will be higher. The air bag is
not designed to inflate in
rollovers, side impacts, or rear impacts, because inflation woul\
d not help the
occupant.
In any particular crash, no one can say whether an air bag should have
inflated simply because of the damage to
a vehicle or because of what the
repair costs were. Inflation is determined by
the angle of the impact and the
vehicle’s deceleration. Vehicle damage is
only one indication of this.
The air bag system is designed to work properly under a wide range
of
conditions, including off-road usage. Observe safe driving speeds,
especially
on rough terrain. As always, wear your safety belt. See
“Off-Road Driving” in the Index for more tips on off-road\
driving.
What makes an air bag inflate?
In a frontal or near-frontal impact of sufficient severity, the air bag sensing \
system detects that
the vehicle is suddenly stopping as a result of a crash.
The sensing system triggers a chemical reaction
of the sodium azide sealed
in the inflator. The reaction produces nitrogen gas, which inflates the air
bag. The inflator, air bag, and related hardware are all part
of the air bag
module packed inside the steering wheel.
How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions, even belted
occupants can contact
the steering wheel. The air bag supplements the
protection provided by safety belts. Air bags distribute the fo\
rce of
the
impact more evenly over the occupant’s upper body, stopping \
the occupant
more gradually. But air bags would not help you
in many types of collisions,
including rollovers and rear and side impacts, primarily because\

an
occupant’s motion is not toward the air bag. Air bags should never be

The outside air
temperature and the
compass are displayed
at the front of the
overhead console. The
control switches are
located
on the driver's
side of the display.
Turn the display on or
off by pressing the ON/OFF switch. Display the
temperature in either degrees Fahrenheit (English) or Celsius (metric) by
pressing the US/MET switch.
Before you turn
on the ignition and move the vehicle, the temperature
indicated will be the last outside temperature recorded with the ignition on.
If the outside temperature is
37 "F (3 "C) or lower when you turn on the
ignition, ICE will appear
on the display. It's a caution to the driver that road
conditions may be icy, and that appropriate precautions should be taken.
Gompass Calibration
The compass is self-calibrating, so it does not need to be manually set.
However, when your vehicle is new, the compass may function er\
ratically. If
it does, CAL (Calibration) will appear
on the display. To correct the
problem, drive in a complete
360" circle three times, and the compass will
function normally.

Downloaded from www.Manualslib.com manuals search engine Normal operating range shows your engine speed during normal driving
conditions.
For example, when the needle points to 2, it means the engine is
running at 2,000 revolutions per minute (rpm). The tachometer needle will
vary all the time that the engine is running.
The red warning range tells you that your engine speed is reaching its upper
limits. Don’t drive very long with the tachometer in the red warning range.
If you have a manual transmission, shift to a higher gear as
soon as possible.
If you have an automatic transmission, lift your foot
off of the accelerator
pedal. If you drive for very long with the tachometer in the red danger
range, engine damage will result.
NOTICE:
Do not operate the engine with the tachometer in the red range,
or engine damage will occur.
The red danger range tells you that your engine speed is at its upper limits.
You should immediately shift to a higher gear, or lift your foot
off of the
accelerator pedal. If you drive for very long with the tachometer in the red
danger range, engine damage will result.
Warning Lights and Indicators
This part describes the warning lights and gages that may be on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is wrong before it
becomes serious enough to cause an expensive repair or replacement.
Paying attention
to your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a problem with one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you start the engine just to let
you know they’re working. If you are familiar with this section, you should
not be alarmed when this happens.
Gages caa indicate when there may be or is a problem with one of your
vehicle’s functions. Often gages and warning lights work together to let you
know when there’s a problem with your vehicle.
When one of the warning lights comes on and stays on when you are
driving, or when one of the gages shows there may be a problem, check the
section that tells you what
to do about it. Please follow this manual’s advice.
Waiting to
do repairs can be costly - and even dangerous. So please get to
know your warning lights and gages. They’re a big help.

The red charging
system light is above
your oil temperature
gage on your
instrument cluster and
will come on briefly
when
you turn on the
ignition,
but the
engine
is not running,
as a check to show
you
it is working.
It should go out once the engine is running. If it stays
on, or comes on while
you are driving, you may have a problem with the charging system. It could
indicate that you have problems with a generator drive belt, or another
electrical problem. Have it checked right away. Driving while t\
his light is on
could drain your battery.
If you must drive a short distance with the light on, be certain to turn off all
your accessories, such as the radio and air conditioner.
Check Gages Light

GAGES
This amber CHECK
GAGES light is above
the
fuel gage on the
instrument cluster and
will come on briefly
when you are starting
the engine.
If the light comes on and stays on while you are driving, check your coolant
temperature and engine oil pressure gages to see
if they are in the warning
zones.

Downloaded from www.Manualslib.com manuals search engine The upper knob changes the air temperature. Turn the knob clockwise for
warmer air. Turn the knob counterclockwise for cooler air.
The lower knob selects the heater
or air conditioning function and
determines which outlets the air will flow through (instrument panel,
defroster, heater, etc
.).
OFF - This setting turns off all heating functions. Some outside air will
still come
out of the heater outlet whenever the vehicle is moving forward.
MAX A/C - Air inside your vehicle is recirculated to maximize your air
conditioner’s performance and your vehicle’s fuel economy. This setting
cools the air the fastest and should be used to keep “unwanted odors” and/or
dust from entering the vehicle.
NORM A/C - This setting cools outside air and directs it through the
instrument panel vents. This setting is useful for normal cooling on hot
days.
BI-LEV A/C
- Air is delivered through the heater floor vents as well as
the instrument panel vents. This setting is useful in cool weather with bright
sunlight.
VENT
- Airflow is through the instrument panel vents. Set the upper knob
to the temperature desired. This setting
is useful for mild outside
temperatures, when little heating or cooling is desired. The air conditioner
does not run.
HEAT
- Heated air comes out through the heater floor vents and
windshield defroster vents. This setting is useful for cold weather.
BLEND
- Airflow is divided equally between the heater floor vent and the
windshield defroster vents. This setting is useful in cool weather when you
have fog or ice on the windshield or side windows.
DEF - This setting directs most air through the windshield defroster vents
and some through the heater vents. This setting is useful when you have fog
or ice on the windshield.
Engine Coolant Heater (Option)
If you use the optional engine coolant heater before starting your engine,
your heating system will produce warmer air faster, to heat the passenger
compartment in cold weather. See “Engine Coolant Heater” in the Index.

L
L
I‘ -a
Your vehicle’s ventilation system supplies outside air to the insi\
de of your
vehicle when it is moving. With the side windows closed, air will flow into
the front air inlet grilles, through the vehicle, and out the rear air exhaust
valve. Outside air will also enter the vehicle when the heater or the
air
conditioning fan is running.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow, or any other
obstruction (such as leaves). The heater and defroster will work far
better, reducing
the chance of fogging the inside of your windows.
0 When you enter a vehicle in cold weather, turn the blower fan to HI for
a
few moments before driving off. This helps clear the intake ducts of
snow and moisture, and reduces the chance of fogging the inside
of
your windows.
0 Keep the air path under the front seats clear of objects. This helps air to
circulate throughout your vehicle.

Downloaded from www.Manualslib.com manuals search engine If No Steam IS Coming From Your Engine
If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
e Tow a trailer. See "Driving on Grades" in the Index.
If
YOU get the overheat warning with no sign of steam, try this for a minute
or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan speed and open the
window as necessary.
3. If you're in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the
highest gear while driving
- AUTOMATIC OVERDRIVE (@) or
DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can drive. Just \
to be safe,
drive slower for about ten minutes.
If the warning doesn't come back on,
you
can drive normally.
If the warning continues, pull over, stop, and park your vehicle \
right away.
If there's still no sign of steam, push the accelerator until the engine speed is
about twice as fast
as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now
see if the warning stops.
But then, if you still have the warning,
turn oflthe engine and get everyone
out
of the vehicle until it cools down.
You may decide not to lift the hood but to get service help right away.
