Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While
You're Parked
It's 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
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch 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.
See ªBlizzardº in the Index.

2-45
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 firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're 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 won't
move. See ªShifting Into PARK (P)º in the Index.
If you are parking on a hill and if you're pulling a
trailer, also see ªTowing a Trailerº in the Index.
Horn
Press at or near the horn symbols on your steering wheel
pad to sound the horn.
Tilt Wheel
A tilt steering wheel allows you to adjust the steering
wheel before you drive. You can raise the steering wheel
to the highest level to give your legs more room when
you exit and enter the vehicle, or you can lower it so that
you're more comfortable while driving.
To adjust the wheel, hold
the steering wheel and pull
the lever. Move the steering
wheel to a comfortable
level, then release the lever
to lock the wheel into place.

2-70 Programming the HomeLink

Transmitter
Do not use the transmitter with any garage door opener
that does not have the ªstop and reverseº feature. This
includes any garage door opener model manufactured
before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming!
The engine should be turned off while programming the
HomeLink Transmitter. Follow these steps to program
up to three channels:
1. If you have not previously programmed a universal
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (approximately 20 seconds). Then release the
buttons. This procedure initializes the memory and
erases any previous settings for all three channels.2. Hold the end of the hand
-held transmitter
approximately one to three inches (three to eight cm)
away from the HomeLink Transmitter making sure
that you can still see the display.
3. Decide which one of the three channels you want to
program. Using both hands, press the hand
-held
transmitter button and the desired button on the
HomeLink Transmitter. Continue to hold both
buttons through Step 4.
4. Hold down both buttons until you see the indicator
light on the HomeLink Transmitter flash, first slowly
then rapidly. The rapid flashing, which could take
up to 90 seconds, indicates that the HomeLink
Transmitter has been programmed. Release both
buttons once the light starts to flash rapidly.

Instrument Panel Cluster
3400 V6 Engine Cluster: United States Version Shown, Canadian Similar
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You'll know how fast
you're going, about how much fuel is in your tank and many other things you need to drive safely and economically.

2-77
3800 V6 Engine Cluster: United States Version Shown, Canadian Similar

2-78 Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). Your
odometer shows how far your vehicle has been driven in
either miles (used in the United States) or in kilometers
(used in Canada).
Your vehicle has a tamper
-resistant odometer. If you see
ERROR, you'll know someone has probably tampered
with it and the numbers may not be accurate.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
But if it can't, then it will be set at zero and a label must
be put on the driver's door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
Your trip odometer tells how far you have driven since
you last reset it.
Your trip/select reset switch will go back and forth
between the odometer and the trip odometer if the
button is pressed and released within 1.5 seconds. If the
button is pressed and held for longer than 1.5 seconds
while in the trip odometer mode, it will be reset to zero.If the button is pressed and held for longer than
1.5 seconds while in the odometer mode, it will
have no effect.
Your trip odometer will work no matter what position
your key is in, and even if the key isn't in.Tachometer (If Equipped)
The tachometer displays the
engine speed in thousands
of revolutions per minute
(rpm). (3800 V6 engine
cluster tachometer shown.)
NOTICE:
Do not operate the engine with the tachometer in
the shaded area, or engine damage may occur.

2-79
Warning Lights, Gages
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 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.
Your vehicle may also have a driver information center
that works along with the warning lights and gages.
See ªDriver Information Centerº in the Index.
Safety Belt Reminder Light
When the key is turned to ON, a chime will come on
for about eight seconds to remind people to fasten
their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds,
then it will flash for about
55 seconds.

2-82 Anti-Lock Brake System Warning Light
(If Equipped)
The anti-lock brake
system warning light
should come on for a
few seconds when
you turn the ignition
key to ON.
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, the anti
-lock brake system needs service
and you don't have anti
-lock brakes. The brake pedal may
be harder to push, or it may go to the floor. It may take
longer to stop. Adjust your driving accordingly.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to ON. 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
(3800 V6 Engine)
The traction control
system warning light
may come on for the
following reasons:

If you turn the system off by pressing the TRAC OFF
button located on the instrument panel, a chime will
sound and the warning light will come on and stay on.
To turn the system back on, press the button again.
The warning light should go off. See ªTraction Control
Systemº in the Index for more information.

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 warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

Engine Coolant Temperature Gage
United States-3400 V6
Engine ClusterUnited States-3800 V6
Engine Cluster
Canada-3400 V6
Engine ClusterCanada-3800 V6
Engine ClusterThis gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During the majority of the operation, the gage
will read 210
F (100
C) or less.
If you are pulling a load or going up hills, it is normal
for the temperature to fluctuate and approach the 250
F
(122
C) mark. When the gage reads greater than 250
F
(122
C), the HOT COOLANT TEMP light will be
illuminated in the message center and a chime will
sound continuously. If the gage reaches the 260
F
(125
C) mark, it indicates that the cooling system is
working beyond its capacity.
See ªEngine Overheatingº in the Index.
