Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
PASS-Key
®
II
The vehicle is equipped
with the PASS-Key
®
II
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
®
II is a passive
theft-deterrent system.
It works when the ignition
key is inserted or
removed from the ignition.
PASS-Key
®
II uses a resistor pellet in the ignition key
that matches a decoder in the vehicle.
When the PASS-Key
®
II system senses that the wrong
key has been inserted into the ignition, it shuts down
the vehicle’s starter and fuel systems. The starter will not
work and fuel will not go to the engine for about three
minutes. If someone tries to start the vehicle again with
the wrong key, or uses another incorrect key during
this time, the vehicle will not start. This discourages
someone from randomly trying keys with different
resistor pellets in an attempt to make a match.
The ignition key must be clean and dry before it is
inserted in the ignition or the engine may not start. If the
engine does not start and the SECURITY warning
light on the instrument panel is flashing, the key may be
dirty or wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. If the vehicle still does not start, the ignition
key may be faulty. Wait about three more minutes and
try a spare ignition key. At this time, you may also
want to check the fuse. See
Fuses and Circuit Breakers
on page 5-98
for information on fuse location. If the
starter will not work with the spare key, the vehicle
needs service. See your dealer or a locksmith who can
service the PASS-Key
®
II.

Turn and Lane-Change Signals
To signal a turn, move the lever up or down. The lever
returns to its original position when the turn is
completed.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
To signal a lane change, raise or lower the lever until
the arrow starts to flash. Hold it there until the lane
change is completed. The lever will return to its original
position when released.
Arrows that flash rapidly when signaling for a turn or
lane change, or that fail to work, may indicate a
burned-out signal bulb or fuse. Other drivers will not see
the signal. See
Front Turn Signal and Parking Lamps
on page 5-56
and
Taillamps, Turn Signal, and
Stoplamps on page 5-58
for turn signal bulb replacement
procedures. Also see
Fuses and Circuit Breakers on
page 5-98
for location of fuses.
A chime will sound if the turn signal is left on for more
than 3/4 mile (1.2 km).
Headlamp High/Low-Beam Changer
To change the headlamps from low beams to high
beams, or high to low, pull the multifunction lever until a
click is heard. Then release it.
This indicator will light on
the instrument panel
cluster when the
high-beam lamps are on.
3-6
Dome Lamp
The dome lamp will come on when you open a door.
Battery Rundown Protection
This helps prevent the vehicle’s battery from draining in
case the interior courtesy lamps, reading lamps,
trunk lamp, underhood lamp, glove box lamps, or sun
visor vanity lamps, if equipped, are accidently left on. If
any of these lamps are left on while the ignition is in
OFF, they will automatically turn off after 20 minutes.
The lamps will not come back on again until one of the
following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then on.
A door is opened.
If the vehicle has less than 15 miles (25 km) on the
odometer, the battery saver will turn off the lamps after
only three minutes.
Accessory Power Outlets
With accessory power outlets you can power electrical
equipment such as a cellular telephone or CB radio.
The vehicle is equipped with a 12-volt outlet. It is located
on the console, near the floor on the passenger’s
side. Open the cover to use the outlet. Be sure to close
the cover when the outlet is not in use.
Notice:
Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Check with your dealer
before adding electrical equipment.
Certain power accessory plugs may not be compatible
to the power accessory outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer.
Notice:
Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
Notice:
Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.

Ashtrays and Cigarette Lighter
The center front ashtray is located below the instrument
panel comfort controls.
To remove the ashtray, open the storage door. Then
open the ashtray lid, lift up and pull it out.
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, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
Push the lighter to use it. When the heating element is
hot, the lighter will pop back out by itself.
Notice:
If you put papers or other flammable items
in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put flammable items in the
ashtray.
Climate Controls
Dual Climate Control System
The vehicle may have this climate control system. The
heating, cooling, and ventilation for the vehicle can
be controlled with it.
Manual Operation
To change the current mode, select one of the following
settings on the right knob.
MAX (Maximum Air-Conditioning):
This mode
recirculates much of the air inside the vehicle and sends it
through the instrument panel outlets. The air-conditioning
compressor will run automatically in this setting unless
the outside temperature is below 40°F (4°C).
3-17
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Light
If the vehicle has a an oil
problem, this light may
stay on after the engine is
started, or come on
while you are driving.
This light indicates that oil is not going through the
engine quickly enough to keep it lubricated. The engine
could be low on oil or could have some other oil
problem. Have it fixed right away.
The oil light could also come on in the following
situations:
The light will come on briefly when the ignition is
turned on to show that it is working properly. If it
does not come on with the ignition on, there may be
a problem with the fuse or bulb. Have it fixed
right away.
Sometimes when the engine is idling at a stop, the
light may blink on and off. This is normal.
{
CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:
Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.

Detection thresholds may be higher and detection times
may be longer on rough roads, curves and at high
speeds. The system is not capable of inflation differences
at speeds greater than 70 mph (110 km/h).
The tire inflation monitor system will not alert you if the
pressure in more than one tire is low, if the system
is not properly calibrated, or if the vehicle is moving
faster than 70 mph (110 km/h).
The LOW TIRE light will stay on while the ignition is on,
until the system is reset
Do not reset the tire inflation monitor system without
first correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If the
system is reset when the tire pressures are incorrect, it
will not function properly and may not alert you when
a tire is low.
Any time a tire’s pressure is adjusted, the tires are
rotated, or one or more tires is repaired or replaced, the
tire inflation monitor system will need to be reset. The
system also needs to be reset when new tires are
purchased and if the vehicle’s battery has been
disconnected.
To reset the system:
1. Turn the ignition to RUN.
2. Remove the passenger’s side instrument panel
cover to get to the fuse block.
3. Press and hold the RESET button in the fuse block
for about five seconds.
4. The LOW TIRE light will come on and flash three
times. Then it will go off. If the light does not go
off, see your dealer for service.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See
When It Is Time
for New Tires on page 5-72
and
Wheel Replacement
on page 5-75
for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See
Scheduled Maintenance
on page 6-4
for scheduled rotation intervals.
5-70
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood fuse block. An electrical overload will
cause the headlamps to go on and off, or in some cases
to remain off. If this happens, have the headlamp
system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel fuse block
protect the power windows and other power accessories.
When the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the
problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and in the fuse block wiring itself. This greatly reduces
the chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Make sure a
bad fuse is replaced with a new one of the identical
size and rating.
Instrument Panel Fuse Block
Some fuses are located in
a fuse block on the
passenger’s side of the
instrument panel. Pull off
the cover labeled FUSES to
expose the fuse block.
