Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-34.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-26.
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle will
not move. SeeShifting Into Park (P) on page 2-31.
If you are parking on a hill and if you are pulling a trailer,
also seeTowing a Trailer on page 4-38.

Turn and Lane-Change Signals
To signal a turn, move the lever up or down. The lever
returns to its original position when the turn is
completed.
An arrow on the instrument
panel cluster will ash in
the direction of the turn or
lane change.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until the lane
change is completed. The lever will return to its original
position when released.
Arrows that ash rapidly when signaling for a turn or lane
change, or that fail to work, may indicate a burned-out
signal bulb or fuse. Other drivers will not see the signal.
SeeFront Turn Signal and Parking Lamps on page 5-53
andTaillamps, Turn Signal, Sidemarker, Stoplamps and
Back-up Lamps on page 5-54for turn signal bulb
replacement procedures. Also seeFuses and Circuit
Breakers on page 5-93for location of fuses.
A chime will sound if the turn signal is left on for more
than 3/4 mile (1.2 km).
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam,
push the turn signal/multifunction lever away from you.
When the high beams
are on, a light on the
instrument panel cluster
also will be on if the
ignition is on.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward you.
Flash-to-Pass
This feature lets you use your high-beam headlamps
momentarily to signal a driver in front of you that
you want to pass.
To use it, pull the turn signal/multifunction lever toward
you until the high-beam headlamps come on, then
release the lever to turn them off.

Use the right knob to select from the following modes:
H(Vent):This mode directs outside air to the
instrument panel outlets. If driving in city traffic, and
the vehicle is stopped and idling, or the weather is hot,
turn on the recirculation mode. To prevent the air inside
the vehicle from becoming stale, after ve minutes
recirculate will allow outside air into the vehicle.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets, and the remaining air to
the oor outlets. Some air may be directed toward the
windshield. Slightly cooler air is directed to the instrument
panel outlets and warmer air is directed to the oor
outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed toward the side
window outlets and a little air directed to the windshield.
In this mode, the system will automatically use outside
air. The air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or below.
If recirculation is selected, the led will come on.You can also select modes by using the following
buttons:
h(Recirculate):Press this button to recirculate
cabin air through the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to help
heat or cool the air inside your vehicle more quickly. An
indicator light below the button will come on in this mode.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode. To prevent the air inside the vehicle
from becoming stale, after ve minutes recirculate will
allow outside air into the vehicle.
#(Air Conditioning):Press this button to turn the
air conditioning system on or off. When this button is
pressed, an indicator light below the button will come
on to let you know the air conditioning is activated. Air
conditioning can be selected in any mode as long as
the fan switch is on. Note that the indicator light will
change with each button press even when conditions
prevent operation.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on and the parking brake
is not applied, there is a brake problem. Have your
brake system inspected right away.
This light should come on
briey when you turn the
ignition key to RUN.
If it does not come on then, have it xed so it will be
ready to warn you if there is a problem.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake does not release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.If the light comes on while you are driving, a chime will
sound and you should 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 oor. It may take longer to
stop. If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-36.
{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 after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.

Engine Coolant Temperature Gage
The vehicle has a gage
that shows the engine
coolant temperature.
If the gage pointer moves towards the H, the engine is
too hot.
This reading indicates the same thing as the warning
light. It means that the engine coolant has overheated.
If the vehicle has been operating under normal driving
conditions, pull off the road, stop the vehicle, and turn off
the engine as soon as possible. SeeEngine Overheating
on page 5-27.
Low Coolant Warning Light
If equipped, this light
comes on briey when
you turn your ignition on
as a bulb check only.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which monitors
operation of the fuel,
ignition, and emission
control systems.
This system is called OBD II (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.
3-41

The check engine 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. This 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 awhile, 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.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 5-3.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 does not come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system
on your vehicle. Diagnosis and service may
be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
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
