Ventilation Tips
·
Clear away any ice, snow or leaves from the air
inlets on the hood that may block the ¯ow of air
into your vehicle. This will help to remove fog
or frost from the windows it will also improve
heating.
·Select the ¯oor mode and set the fan at the highest
speed when ®rst starting your vehicle to help clear
the air intake ducts of moisture or snow. This
will also help to remove fog from the windows.
·Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air ®lter. It is located
underneath the hood just below the windshield wiper
arm on the passenger's side of the vehicle, underneath
the air inlet grille.
The ®lter traps most of the pollen from air entering the
Climate Control System. Like your engine's air
cleaner/®lter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
®lter, see
Scheduled Maintenance on page 6-5.

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 brie¯y 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
(DIC) that works along with the warning lights and
gages. See
Driver Information Center (DIC) on
page 3-52.

Instrument Panel Cluster
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.

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 tozero. 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
The tachometer displays
the engine speed in
thousands of revolutions
per minute (rpm).
Notice:Do not operate the engine with the
tachometer in the shaded warning area, or engine
damage may occur.The 3800 V6 Engine

If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not in¯ate in a crash, or they
could even in¯ate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should ¯ash for a few
seconds when you turn the ignition key to ON. If the
light doesn't come on then, have it ®xed so it will
be ready to warn you if there is a problem.
Voltmeter Gage
If your vehicle is equipped
with the 3800 V6 engine it
has a voltmeter gage
that indicates battery
voltage.
If the gage reads less than 12 volts or more than
16 volts while the engine is running, and it stays there,
you may have a problem with the electrical charging
system.
Also, when your gage reads less than 11 volts or
more than 16 volts, your battery life indicator will be
illuminated in the message center. For more information
see
Battery Warning Message on page 3-45.

Anti-Lock Brake System Warning
Light
If your vehicle has ABS,
the anti-lock brake system
warning light will 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 anti-lock brake system warning light will come on
brie¯y when you turn the ignition key to ON. This is
normal. If the light doesn't come on then, have it ®xed
so it will be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
If your vehicle has the
traction control system,
this warning light may
come on for the
following reasons:
·If you turn the system off by pressing the TRAC
OFF button located on the center console, 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
Traction Control System (TCS) on page 4-8for
more information.
·If there's a brake system problem that is speci®cally
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 GageThis 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 210ÉF (100ÉC) or less.
If you are pulling a load or going up hills, it is normal for
the temperature to ¯uctuate and approach the 250ÉF
(122ÉC) mark. When the gage reads greater than 250ÉF
(122ÉC), the HOT COOLANT TEMP light will be
illuminated in the message center and a chime will
sound continuously. If the gage reaches the 260ÉF
(125ÉC) mark, it indicates that the cooling system is
working beyond its capacity.

Engine Overheating on page 5-29.
