Ashtrays and Cigarette Lighter
The front ashtray and cigarette lighter are located at
the lower part of the center instrument panel, behind a
cover. Press in the cover and it will automatically open.
To remove the front ashtray for cleaning, pull the bin
out. To replace, press the bin back into place.
The rear ashtray is located at the rear of the center
console. To remove the rear ashtray, press in the
retaining spring and pull the bin out. To replace the rear
ashtray, insert the bottom tabs first and then press in
the retaining spring and push the ashtray closed.
Notice:If you put papers or other ammable items
in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put ammable items in the
ashtray.
The cigarette lighter is located to the right of the front
ashtray. To use it, turn the ignition to ACC or ON, push
the cigarette lighter in all the way and let go. When it
is ready, it will pop back out by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element. Do not hold a cigarette lighter in while it
is heating.
Climate Controls
Climate Control System
Your vehicle may have a manual climate control system.
With this system you can control the heating, cooling and
ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
In any setting other than off, the fan will run continuously
with the ignition on. The fan must be on in order for
the air conditioning compressor to run.
0 (Off):To turn the fan off, turn the knob all the way
counterclockwise to the off position.

Engine Coolant Temperature Gage
Your vehicle has an
engine coolant temperature
gage. With the ignition
turned to ON, this
gage shows the engine
coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot. It means that your engine coolant has
overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-22.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with 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. 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.

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked
by your dealer or service center when you have your
oil changed.
Have your dealer or service center change both the fluid
and filter every 50,000 miles (83 000 km) if the vehicle
is mainly driven under one or more of these conditions:
•In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•In hilly or mountainous terrain.
•Uses such as found in taxi, police or delivery
service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
Notice:Use of automatic transaxle uid labeled
other than ESSO LT71141 or TOTAL ATF H50235
may damage your vehicle, and the damages may
not be covered by your warranty. Always use
ESSO LT71141 or TOTAL ATF H50235 labeled
automatic transaxle uid.
Engine Coolant
The following explains your cooling system and how
to add coolant when it is low. If you have a problem with
engine overheating, seeEngine Overheating on
page 5-22.
A 50/50 mixture of clean, drinkable water and proper
coolant will:
•Give freezing protection down to−22°F (−30°C).
•Give boiling protection up to 268°F (131°C).
•Protect against rust and corrosion.
•Help keep the proper engine temperature.
•Let the warning lights and gages work as they
should.
What to Use
Use a 50/50 mixture ofclean, drinkable waterand coolant
that meets GM specification 1825M, which will not
damage aluminum parts. You can also use a recycled
coolant confirming to GM specification 1825M with a
complete coolant flush and refill. If you use this coolant
mixture, you do not need to add anything else.
5-19

Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-39.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood.
Stay away from the engine if you see or hear
steam coming from it. Just turn it off and get
everyone away from the vehicle until it cools
down. Wait until there is no sign of steam
or coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned.
Stop your engine if it overheats, and get out
of the vehicle until the engine is cool.
Notice:If your engine catches re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not
be covered by your warranty.
5-22

The coolant level should
be between the MIN (B)
and MAX (A) marks on the
coolant surge tank when
the engine is cool.
If it is not, you may have a leak at the pressure cap
or in the radiator hoses, heater hoses, radiator, water
pump or somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive
the vehicle.
If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fan is running.
If the engine is overheating, the fan should be running.
If it is not, your vehicle needs service.
Notice:Engine damage from running your engine
without coolant is not covered by your warranty.
5-25

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your GM Warranty booklet for details. For additional
information refer to the tire manufacturer’s booklet
included with your vehicle’s Owner Manual.
{CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause
overheating as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle”
in the Index.
CAUTION: (Continued)
CAUTION: (Continued)

Underinated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinated tires are more likely to be
cut, punctured or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
Tire Sidewall Labeling
Useful information about a tire is molded into its sidewall.
The examples below show a typical passenger car tire
sidewall.
