NOTICE:
If’ your vehicle seems to start up rather slowly, or
if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor.
If you drive very far that way, your
vehicle can be damaged.
So, if this happens, have
your vehicle serviced right away. Until then, you
can use
SECOND (2) when you are driving less
than
35 mph (55 km/h) and THIRD (3) for
higher speeds. FIRST
(1): This position
gives you even more power
(but lower fuel economy) than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If the
selector lever is put in
FIRST (1), the transaxle won’t
downshift into first gear until the vehicle is going
slow enough.
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen
if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with
only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into PARK
(P)
to hold your vehicle in position on a hill.

To use your air inflator system, attach the appropriate
nozzle adapter, if required, to the end of the hose that
has the pressure gage. Then attach that end of the hose
to the object you wish to inflate. Remove the protective
cap covering the outlet. Attach the other end of the hose
to the outlet. Press the ON switch. The
ON switch will
work even with the ignition
off.

If the air inflator system does not turn on, the fuse may
be blown or installed incorrectly. See “Fuses and Circuit
Breakers” in the Index or see your retailer for service.
Your air inflator will automatically shut off after about
10 minutes. To reset, press the ON switch again.
Don’t run your air inflator for longer than
30 minutes at
one time.
If you do, you may damage the system. After
30 minutes, wait at least 10 minutes before restarting the
air inflator.
To turn off the inflator, press OFF and detach the hose,
first from the inflated object, then from the outlet.
Replace the protective cap. Place the inflator kit tools
in
the pouch, and store in the glove box.
To replace the cover, line up the tabs at the back of the
cover and put it in place. Push down the tab to secure
the cover.

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 chime will
come on for about eight seconds to remind people to
fasten their safety belts.
The safety belt light will
also come on and stay on
for about
70 seconds. If the
driver’s belt is already
buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows a deployed air bag. The system
checks the air bag’s electrical system for malfunctions.
The light tells
you if there is an electrical problem. The
system check includes the air bag sensors, the air bag
module, the wiring and the diagnostic module. For more
information on the air bag system, see “Air Bag” in
the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system
is ready.
If the air bag readiness light stays on after you
start the
engine or comes
on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready
to warn you if there is a problem.

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, or if the
anti-lock brake system warning light is flashing, have
the vehicle towed for service. (See “Anti-Lock Brake
System Warning Light” and “Towing Your Vehicle” in
the Index
.)
I A CAUTION:
Your brake system may not be working properly
if the brake system warning light
is on. Driving
with the brake system warning light on can lead
to an accident.
If the light is still on or if the
anti-lock brake system warning light
is flashing
after you’ve pulled
off the road and stopped
carefully, have the vehicle towed for service.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and it will stay on
for three seconds.
That’s normal.
If the light flashes when you’re driving, you don’t have
anti-lock brakes and there could be a problem with
your
regular brakes. Pull off the road and stop carefully. You
may notice that the pedal is harder to push. Or, the pedal
may go closer to the floor. It may take longer to stop.
Have the vehicle towed for service. (See “Towing Your
Vehicle” in the Index.)

A CAUTION:
Your regular brake system may not be working
properly if the anti-lock brake system warning
light is flashing. Driving with the anti-lock brake
system warning light flashing can lead to an
accident. After you’ve pulled off the road and
stopped carefully, have the vehicle towed
for service.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re driving, stop
as soon as possible and turn
the ignition off. Then start the engine again to reset the
system.
If the light still stays on, or comes on again
while you’re driving, your vehicle needs service.
If the
light is on but not flashing and the regular brake system
warning light isn’t on, you still have brakes, but
you
don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have
it fixed so it will be
ready to warn you if there
is a problem.
Traction Control System Warning Light
(Option)
This warning light should
come on briefly as you start
the engine.
If the warning
light doesn’t come on then,
have
it fixed so it will be
ready
to warn you if there’s
a problem.
If it stays
on, or comes on when you’re driving, there
may be
a problem with your traction control system and
your vehicle may need service. When this warning light
is on,
the system will not limit wheel spin. Adjust your
driving accordingly.
2-90
ProCarManuals.com

The traction control system warning light may come on
for the following reasons:
If there’s a brake system problem that is specifically
related to traction control, the traction control system
will turn
off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays
on for an extended period of time when the
system
is turned on, your vehicle needs service.
Low Traction Light (Option)
LOW
TRACTION
If your vehicle has the
traction control system,
there will be a
LOW
TRACTION light on the
instrument panel.
When your anti-lock system is adjusting brake pressure
to help avoid a braking skid, or when your traction
control system is limiting wheel spin, the
LOW
TRACTION light will come on. Slippery road
conditions may exist if this light comes on,
so adjust
your driving accordingly. The light will come on and
stay
on for four seconds when your anti-lock system
adjusts brake pressure for less than four seconds or
when your traction control system limits wheel spin for
less than four seconds. Otherwise, the light will
go out
as soon as the anti-lock system
stops adjusting brake
pressure or the traction control system stops limiting
wheel spin.
The
LOW TRACTION light also comes on briefly, as a
bulb check, when the engine is started. If the light
doesn’t come on then, have it fixed
so it will be there to
tell you when
the system is active.

Low Coolant Light
If this light comes
on, your system is low
on coolant and the
engine may overheat.
To prevent damage to your engine, immediate
action
is required.
See “Engine Coolant” in the Index and have your
vehicle serviced
as soon as possible.
Malfunction Indicator Lamp (Service Engine Soon Light)
SERVICE
ENGINE
SOON
United States
CHECK
Canadian
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. The SERVICE ENGINE SOON light
comes on and
a chime will sound to indicate that there is
a problem and service is required. Malfunctions often
will be indicated by the system before any problem is
apparent. This may prevent more serious damage to
your vehicle. This system is
also designed to assist
your service technician
in correctly diagnosing
any malfunction.
2-93
ProCarManuals.com

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. Retailer or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected
on your vehicle.
Retailer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it
is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues
to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
retailer or qualified service center for service.

If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if
the fuel
cap has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn
the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off. Have
you recently changed brands
of fwl?
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 one or more of these conditions,
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 retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
