Lockout Protection
This feature helps prevent locking your key in the car.
The driver’s door can only be locked with the door
closed. From the outside of the vehicle, close the
driver’s door and lock it using the key or the remote
keyless entry transmitter, if equipped.
This feature cannot guarantee that you will never be
locked out of your vehicle. Always remember to
take your key with you.
Trunk (Sedan)
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the trunk lid open or if
electrical wiring or other cable connections
must pass through the seal between the body
and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-30.
To open the trunk on your sedan from outside of your
vehicle, insert the key into the lock cylinder and turn the
key clockwise or use the remote keyless entry
transmitter, if equipped.

Liftgate (Hatchback)
{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the liftgate
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. SeeClimate Control
System on page 3-18.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-30.To open the liftgate on your hatchback from outside of
the vehicle, insert the key into the lock cylinder and
turn it counterclockwise or use the remote keyless entry
transmitter, if equipped. Then pull up the handle
above the license plate to open the liftgate.
When closing the liftgate, close from the center to
ensure it fully latches.
To lock the liftgate, insert the key into the lock cylinder
and turn it clockwise or use the remote keyless entry
transmitter, if equipped.
The liftgate can also be locked or unlocked by the
central door unlocking system or remote keyless entry,
if equipped. SeeCentral Door Unlocking System on
page 2-7andRemote Keyless Entry System Operation
on page 2-5.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Temperature Control:Turn the left knob clockwise or
counterclockwise to manually increase or decrease
the temperature inside your vehicle. Turn the knob to the
blue area for cool air and to the red area for warm air.
9(Fan):Turn the middle 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.To change the current mode, select one of the following
from the right knob:
Y(Vent):This mode directs air to the instrument panel
outlets.
\(Bi-Level):This mode directs about half of the air
to the instrument panel outlets, and then directs the
remaining air to the floor outlets.
[(Floor):This mode directs most of the air to the
floor outlets. Some of the air will also be directed to the
rear outlets. Be sure to keep the area under the front
seats clear to allow the flow of air to the rear
compartment.
The right knob can also be used to select the defog and
defrost modes. Information on defogging and defrosting
can be found later in this section.
?(Recirculation):This mode keeps outside air
from coming into 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.
If your vehicle has a recirculation button (uplevel
model), press the button to turn the recirculation mode
on. When the button is pressed, an indicator light in
the button will come on. Press the button again to return
to outside air mode. Uplevel shown, Base similar

Highway Hypnosis
Is there actually such a condition as highway hypnosis?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the
wind against the vehicle that can make you sleepy. Do
not let it happen to you! If it does, your vehicle can
leave the road in less than a second, and you could
crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
•Make sure your vehicle is well ventilated, with a
comfortably cool interior.
•Keep your eyes moving. Scan the road ahead and
to the sides. Check your rearview mirrors and your
instruments frequently.
•If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
•Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system,
and transaxle. These parts can work hard on
mountain roads.

need to check your engine
oil level right away.
For more information, seeOil Pressure Light on
page 3-37.
You should check your engine oil level regularly; this is
an added reminder.

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 5-24.
A 50/50 mixture of clean, drinkable water and proper
coolant will:
•Give freezing protection down to−34°F (−37°C).
•Give boiling protection up to 265°F (129°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 of clean, drinkable water and coolant
that meets GM Specification 1825M, which will not
damage aluminum parts. You can also use a recycled
coolant conforming 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.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and the proper coolant.
Notice:If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The
repair cost would not be covered by your warranty.
Too much water in the mixture can freeze and crack
the engine, radiator, heater core, and other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
5-22

Notice:If you use extra inhibitors and/or additives in
your vehicle’s cooling system, you could damage
your vehicle. Use only the proper mixture of the
engine coolant listed in this manual for the cooling
system. SeePart D: Recommended Fluids and
Lubricants on page 6-25for more information.
Checking Coolant
The engine coolant surge tank is located in the rear of
the engine compartment on the driver’s side of the
vehicle. SeeEngine Compartment Overview on
page 5-12for more information on location.
{CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. Never turn the surge tank pressure
cap — even a little — when the engine and
radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be between the
Maximum (A) and Minimum (B) marks on the coolant
surge tank. The level rises at engine operation
temperature and drops again when the engine
cools down.
