Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun visor
says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing child
is so great, if the airbag deploys.{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system
is designed to turn off the passenger’s frontal
airbag and seat-mounted side impact airbag
(if equipped) under certain conditions, no
system is fail-safe, and no one can guarantee
that an airbag will not deploy under some
unusual circumstance, even though it is
turned off. General Motors recommends that
rear-facing child restraints be secured in
the rear seat, even if the airbag is off.
If you need to secure a forward-facing child
restraint in the right front seat, always move
the front passenger seat as far back as it will
go. It is better to secure the child restraint in
a rear seat.

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system
is designed to turn off the passenger’s frontal
airbag and seat-mounted side impact airbag
(if equipped) under certain conditions, no
system is fail-safe, and no one can guarantee
that an airbag will not deploy under some
unusual circumstance, even though it is
turned off. General Motors recommends that
rear-facing child restraints be secured in
the rear seat, even if the airbag is off.
If you need to secure a forward-facing child restraint in
the right front seat position, move the seat as far
back as it will go before securing the forward-facing
child restraint. SeeManual Passenger Seat on
page 1-3,Six-Way Power Seats on page 1-3or
Eight-Way Power Seats on page 1-4.If your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-46.
There is no top strap anchor at the right front seating
position. Do not secure a child seat in this position if a
national or local law requires that the top strap be
anchored or if the instructions that come with the child
restraint say that the top strap must be anchored. See
Top Strap on page 1-44if your child restraint has one.
You will be using the lap-shoulder belt to secure the child
restraint in this position. Be sure to follow the instructions
that came with the child restraint. Secure the child in the
child restraint when and as the instructions say.
1. Your vehicle has airbags. SeePassenger Sensing
System on page 1-62. General Motors recommends
that rear-facing child restraints be secured in a rear
seat, even if the airbag or airbags are off. If your child
restraint is forward-facing, move the seat as far back
as it will go before securing the child restraint in this
seat. SeeManual Passenger Seat on page 1-3,
Six-Way Power Seats on page 1-3orEight-Way
Power Seats on page 1-4.
When the passenger sensing system has turned off
the right front passenger’s airbag or airbags, the off
indicator in the passenger airbag status indicator
should light and stay lit when you turn the ignition to
RUN or START. SeePassenger Airbag Status
Indicator on page 3-35.
1-51

The passenger sensing system will turn off the right
front passenger’s frontal airbag and side impact airbag
(if equipped) under certain conditions. The driver’s
airbag or airbags are not part of the passenger sensing
system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence
of a properly-seated occupant and determine if the
passenger’s airbag or airbags should be enabled
(may inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.

Notice:Shifting out of PARK (P) or NEUTRAL (N)
while the engine is running at high speed may
damage the transaxle. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speeds when shifting your vehicle.
AUTOMATIC OVERDRIVE (D):This position is for
normal driving. If you need more power for passing, and
you are:
Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have more
power.
Notice:If your vehicle seems to start up rather
slowly or not shift gears when you go faster, and
you continue to drive your vehicle that way, you
could damage the transaxle. Have your vehicle
serviced right away. You can drive in SECOND (2)
when you are driving less than 35 mph (55 km/h)
and AUTOMATIC OVERDRIVE (D) for higher speeds
until then.
Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35°F (2°C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed until
the engine is warmed up. This is a normal condition
designed to provide heat to the passenger compartment
and defrost the windows more quickly. SeeDual
Climate Control System on page 3-25for more
information.
THIRD (3):This position is also used for normal driving,
but it offers more power and lower fuel economy than
AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads
When towing a trailer, so there is less shifting
between gears
When going down a steep hill
2-35

How the System Works
Unless disabled, the URPA will turn on automatically
when the shift lever is moved into REVERSE (R). When
the system turns on, the three lights on the display
will illuminate for one and a half seconds to let you know
that the system is working. If your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h),
the red light will ash to remind you that the system
does not work at speed greater than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed of less
than 3 mph (5 km/h), one of the following will occur:
Description English Metric
amber light 5 ft 1.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights &
continuous chime20 in 0.5 m
amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
A chime will sound the rst time an object is detected
between 20 inches (0.5 m) and 5 feet (1.5 m) away.URPA cannot detect objects that are above liftgate
level. In order for the rear sensors to recognize
an object, it must be within detection range behind the
vehicle.
When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R) if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush. Other conditions that may
affect system performance include things like the
vibrations from a jackhammer or the compression of air
brakes on a very large truck. If after cleaning the
rear bumper and then driving forward at least 15 mph
(25 km/h), the display continues to ash red, see
your dealer.
If a trailer was attached to your vehicle, or a bicycle or
an object was on the back of, or hanging out of your
liftgate during your last drive cycle, the light may
also ash red. The light will continue to ash whenever
in REVERSE (R) until your vehicle is driven forward
at least 15 mph (25 km/h) without any obstructions
behind the vehicle.

Outside Air:This mode will be automatically selected
when your vehicle is in any mode except maximum
air conditioning.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan
speed. Turn the knob to 0 to turn off the fan. The fan
must be turned on for the air conditioning compressor
to operate.
Temperature Control:Use the driver’s and
passenger’s levers to increase or decrease the air
temperature inside your vehicle.
#(Air Conditioning):Press this button to turn the
air conditioning system on or off. When it is pressed, an
indicator light in the button will come on to let you
know that air conditioning is activated.
You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
The air conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
#MAX (Maximum Air Conditioning):Turn the
right knob to this position for maximum air conditioning.
This will select air conditioning and recirculation for
maximum cooling of your vehicle.
Recirculation:This mode keeps outside air from
coming in the vehicle. It can be used to prevent outside
air and odors from entering your vehicle or help heat
or cool the air inside your vehicle more quickly.
This mode will automatically be selected when you
select maximum air conditioning.
3-26

((Heated Seats):Press this button to turn on the
heated seats. The button on the left controls the driver’s
seat and the button on the right controls the passenger’s
seat. SeeHeated Seats on page 1-4for additional
information.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity,
or moisture, condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or
frost from the windshield more quickly.Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs air to the windshield
and the oor outlets. When you select this mode,
the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is at or below freezing. The recirculation mode cannot
be selected while in the defog mode.
0(Defrost):This mode directs most of the air to the
windshield and the side window outlets, with some
air directed to the oor outlets. In this mode, the system
will automatically turn off recirculation and run the air
conditioning compressor, unless the outside temperature
is at or below freezing. Recirculation cannot be
selected while in the defrost mode.
Do not drive the vehicle until all the windows are clear.

Charging System Light
The charging system light
will come on briey when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have
a problem with the charging system. It could indicate
that you have problems with a generator drive belt,
or another electrical problem. Have it checked
right away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a problem.

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.Notice:If you keep driving your vehicle with
this light on, after awhile, your emission controls
may not work as well, your fuel economy may not be
as good, and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on, as a check to show you it
is working, when the ignition is on and the engine is not
running. If the light does not come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.

5. To start the compass calibration, press and hold
the set/reset button until CALIBRATION BEGUN
DRIVE UNTIL DONE appears in the DIC display.
6. Drive the vehicle slowly in a circle two times to
activate the compass.
When the calibration is complete, the DIC will
display CALIBRATION FINISHED.
DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another.
Some messages may not require immediate action, but
you can press any of the DIC buttons to acknowledge
that you received the message and clear it from the
DIC display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared.If there are any active warning messages when the
vehicle is turned off, two chimes will sound and the
DIC will go into a reminder mode. The reminder
mode displays any active message. If there are multiple
messages, the DIC will display each message for
ve seconds. After each active message is displayed
once, the reminder mode will turn off.
You should take any messages that appear on the
display seriously and remember that clearing the
messages will only make the messages disappear,
not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
A/C OFF FOR ENGINE PROTECTION
This message will display when the engine coolant
becomes hotter than the normal operating temperature.
SeeEngine Coolant Temperature Gage on page 3-39.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal, the
air conditioning compressor will turn back on. You can
continue to drive your vehicle.
This message will come on while the ignition is in RUN.
Press any of the DIC buttons to acknowledge this
warning message and to clear it from the screen.
