Operation Tips
·
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ¯ow of air into your vehicle.
·Use of non-GM approved hood de¯ectors may
adversely affect the performance of the system.
·Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
·If the air¯ow seems low when the fan speed is at
the highest setting, the passenger compartment
air ®lter may need to be replaced. For more
information, see
Passenger Compartment Air Filter
on page 3-36andPart A: Scheduled Maintenance
Services on page 6-4.
Rear Climate Control System
Your vehicle has a rear climate-control system that
allows the rear-seat passengers to adjust the direction
of the air¯ow, the fan speed and the temperature for the
rear-seating area. This system also works with the
main climate-control system in your vehicle.
The control panel for this system is located on the back
of the center console.
3-34

y9z(Fan):Pressing this switch cancels automatic
operation and places the system in manual mode.
Press this switch to increase or decrease the fan speed.
Press the MODE switch until AUTO is displayed to
return to automatic operation.
yTEMPz(Temperature):Press this switch to
increase or decrease the temperature for the rear seat
passengers.
For cool air to be sent to the rear of the vehicle, the
air-conditioning system on the main climate-control
panel must be on. If it is not on, then the temperature in
the rear of the vehicle will remain at cabin temperature.
Be sure to keep the area under the front seats clear
of any objects so that the air inside of your vehicle can
circulate effectively.
Passenger Compartment Air Filter
The passenger compartment air ®lter traps most of the
pollen from the air entering your vehicle. Like your
vehicle's engine air cleaner/®lter, it may need to
be changed periodically. For how often to change the
passenger compartment air ®lter, see
Part A: Scheduled
Maintenance Services on page 6-4.
The access panel for the passenger compartment air
®lter is located under the hood near the windshield,
on the passenger's side of the vehicle.

The correct tire in¯ation pressure should be set to those
shown on the Tire Loading-Information Label, located on
the rear edge of the driver's door. For more information
regarding proper tire in¯ation, see
In¯ation -- Tire
Pressure on page 5-61. If a tire is low, you should stop as
soon as possible and inspect your tire(s) for damage. If a
tire is ¯at, see
If a Tire Goes Flat on page 5-71.
Once the TPM system detects the low or high tire
pressure condition, the message CHECK TIRE
PRESSURE will be displayed whenever you start the
engine. To remove or clear the CHECK TIRE
PRESSURE message, you will need to set the tire(s) to
the proper tire pressure. See
In¯ation -- Tire Pressure on
page 5-61.
{CAUTION:
When the CHECK TIRE PRESSURE message is
displayed on the Driver Information Center and
the tire pressure is low, your vehicle's
handling capabilities will be reduced during

severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Don't drive over 55
mph (90 km/h) when the tire pressure is low.
Drive cautiously and correct the tire pressure
as soon as you can.
CHECK WASHER FLUID ± 25:This message means
that your vehicle is low on windshield washer ¯uid.
See
Windshield Washer Fluid on page 5-37.
DRIVER DOOR AJAR ± 140:This message will
display anytime the key is in ON, the transaxle is not in
PARK (P) and the driver's door is open or ajar. A
chime will sound when the vehicle's speed is greater
than 3 mph (4.8 km/h).
DRIVE NO. X (1 OR 2):This message will be displayed
with the key in ON and while entering FEATURE
PROGRAMMING, but only if the vehicle is equipped
with memory seats. The message will show which driver
is activating the personalization feature. It will only
stay on for ®ve seconds. This message can be
customized for you by your dealer.

If you put things inside your vehicle ± like suitcases,
tools, packages or anything else ± they will go as fast as
the vehicle goes. If you have to stop or turn quickly,
or if there is a crash, they'll keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
·Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can.
Try to spread the weight evenly.
·Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
·Don't leave an unsecured child restraint in
your vehicle.
·When you carry something inside the
vehicle, secure it whenever you can.
Automatic Level Control
This feature keeps the rear of your vehicle level as the
load changes. It's automatic ± you don't need to adjust
anything.
Towing a Trailer
{CAUTION:
If you don't use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well Ð or
even at all. You and your passengers could be
seriously injured. You may also damage your
vehicle; the resulting repairs would not be
covered by your warranty. Pull a trailer only if
you have followed all the steps in this section.
Ask your dealer for advice and information
about towing a trailer with your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what
the vehicle trailering capacity is for your vehicle, you
should read the information in ªWeight of the Trailerº that
appears later in this section. But trailering is different
than just driving your vehicle by itself. Trailering means
changes in handling, durability and fuel economy.
Successful, safe trailering takes correct equipment, and
it has to be used properly.

Service Parts Identi®cation Label
You'll ®nd this label on the under side of the spare tire
cover in the trunk. It's very helpful if you ever need
to order parts. On this label is:
·your VIN,
·the model designation,
·paint information and
·a list of all production option and special equipment.
Be sure that this label is not removed from the
vehicle.
Electrical System
Add-On Electrical Equipment
Notice:Don't add anything electrical to your
vehicle unless you check with your dealer ®rst.
Some electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-59.
Headlamp Wiring
The headlamp wiring system has four individual fuses,
LF low, RF low, LF high and RF high. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have
the headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker. If the wiper motor overheats due to
heavy snow, the wipers will stop until the motor cools
and will then restart.
A fuse powers the wiper motor. If the fuse blows, there
is an electrical problem. Be sure to have it ®xed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and power
seats. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is ®xed or goes away.
