Air bags inflate with great force, faster than the
blink of an eye.
If you’re too close to an inflating
air bag, it could seriously injure you. Safety belts
help keep you in position for an air bag inflation
in a crash. Always wear your safety belt, even
with
an air bag, and sit as far back as you can
while still maintaining control
of your vehicle.
AIR
BAG
There is an air bag
readiness light on the

Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in
a crash the child might slide under the belt. The
belt’s force would then be applied right on the child’s abdomen. That could cause serious or
fatal injuries. ~ But if a safety belt isn’t long enough to fasten, your
’ dealer will order you an extender. It’s free. When you go
in
to order it, take the heaviest coat you will wear, so the
extender will be long enough for you. The extender will
be just for you, and just for the seat
in your vehicle that
you choose. Don’t let someone else use
it, and use it
only for the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
I I Checking Your Restraint Systems

pelvic bones in a crash. loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, have it repaired.
Torn or frayed safety belts may not protect
you in a
crash. They can rip apart under impact forces. If a belt is
torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Downloaded from www.Manualslib.com manuals search engine The front axle portion of the indicator diagram will light
up when you shift into four-wheel drive.
Some delay between shifting and the indicator's lighting
is normal. If the indicator light does not light up, or if
the front axle light does not go out after you shift out of
four-wheel drive, have your dealer check your system.
An indicator near the lever shows you the transfer
case settings:
2H (2-Wheel High): This setting is for driving in most
street and highway situations. Your front axle is not
engaged in two-wheel drive.
4H (4-Wheel High): This setting engages your front
axle
to help drive your vehicle. Use 4H when you need
extra traction, such as on wet
or icy roads, or in most
off-road situations.
N '(Neutral): Shift to this setting only when your vehicle
needs to be towed or when using a power take-off.
4L (4-Wheel Low): This setting also engages your front
axle to give you extra power, but should be used- only
for off-road driving.
You can shift from 2-WHEEL HIGH (2H) to 4-WHEEL
HIGH (4H) or from 4-WHEEL HIGH (4H) to 2-WHEEL
HIGH
(2H) while the vehicle is moving. Your front axle
may engage faster if you take
your foot off of the
accelerator for a few seconds after you shift.
In extremely
cold weather, it may be necessary to stop or slow the
vehicle to
shift out of 2-WHEEL HIGH (2H). .

Downloaded from www.Manualslib.com manuals search engine Warning Lights, Gages
and Indicators
This part describes the warning lights and gages tha .t
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 can 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.
Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.

then it will flash for about
55 seconds. If the driver’s
belt is already buckled,
neither the tone nor the

the system is ready.
If the air bag readiness light doesn’t come on when you
start your vehicle, or stays on, or comes on when you
are driving, your air bag system may not work properly.
Have your vehicle serviced right away.
Charging System Warning Light
I-+I
The charging system
warning light should come
on briefly when you turn on
the ignition, before starting
the engine, as a check to
show you it is working.
After the engine starts, the light should
go out. If it stays
on or comes on while you are driving, you may have a
problem with your charging system. It could indicate a
problem with the alternator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light
on, it
helps to turn off all your accessories, such as the radio
and air conditioner.

Engine
Soon Light) (Gasoline Engine)
SERVICE
ENGINE
SOON
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE
SOON
light comes on to indicate that there is a problem and
service is required. Malfunctions often will be indicated
by the system before any problem is apparent, which
may prevent more serious damage to your vehicle. This
system
is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is
on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage
the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
"Fuel" in the .Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation
on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to turn the light
off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Gage
0 \ 80
The oil pressure gage
shows the engine oil
pressure in psi (pounds
per square inch) when the
engine is running. Canadian
vehicles indicate pressure
in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problem'causing low
oil pressure. Check your oil as soon as possible.
2-65

Downloaded from www.Manualslib.com manuals search engine 1 CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon
as possible and have your
vehicle serviced.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.
Daytime Running Lamps (DRL) Indicator Light
This light will go on
whenever the
DRL are on.
When it begins to get dark, the
DRL indicator light is a
reminder
to turn on your headlamps.
