If you park in a lot where someone will be watching
your vehicle, it’s best
to lock it up and take your keys.
But what
if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your front

compartment.
Passlock@
Your vehicle is equipped with the Passlock
theft-deterrent system.
Passlock
is a passive theft-deterrent system. The system
is armed once the key is removed from the ignition.
Passlock enables fuel if the ignition lock cylinder is
turned with
a valid key. If a correct key is not used,
fuel
is disabled. During normal
operation, the SECURITY light will
go
off after the engine is started.
If the engine stalls and the SECURITY light flashes,
wait
until the light stops flashing before trying to restart
the engine. Remember
to release the key from the
START position as soon as the engine starts.
If you are driving and the SECURITY light comes on, you
will be able to restart the engine if you turn the engine off.
However, your Passlock system is not working properly
and must be serviced by your dealer. Your vehicle is not
protected by Passlock at this time. You may
also want to
check the fuse (see “Fuses
and Circuit Breakers” in the
Index). See your dealer for service.
If the SECURITY light comes on while the engine is
running, a problem has been detected and the system
may need service. See your dealer for service.
In an emergency, call the
GM Roadside Assistance
Center. See “Roadside Assistance’’ in the Index.

Downloaded from www.Manualslib.com manuals search engine Turn Signal and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow
you to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is finished, the lever
will return automatically.
H
LI
An arrow on the instrument
panel will flash
in the
direction of the turn or
lane change.
To signal
a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it. As
you signal a
turn or a lane change, if the arrows flash
at twice the normal rate,
a signal bulb may be burned
out and other drivers may not see your turn signal.
If
a bulb is burned out, replace it to help avoid an
accident. If
the arrows don’t go on at all when you
signal a turn, check for burned-out bulbs and a blown
fuse (see “Fuses and Circuit Breakers”
in the Index).
Headlamp High/Low Beam Changer
To change the headlamps from low beam to high or high
to low, pull the multifunction lever all the way toward
you. Then release it.
When the high beams are
on, this light on the
instrument panel also will
be on.

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. 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”
in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to flicker on and off, or in some cases to remain
off.
If this happens, have your headlamp wiring 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.
Although the circuit
is protected from electrical
overload, overload due to heavy snow, etc., may cause
wiper linkage damage. Always clear ice and heavy snow
from the the windshield before using the windshield
wipers.
If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.

The fuse block access door
is
on the driver’s side of
the instrument panel above
the hood release lever.
You can remove the cover
by turning the fastener to
the left.
You can remove fuses with
a fuse extractor. The fuse
extractor
is mounted to the fuse block access door.
To remove fuses if you don’t have a fuse extractor, hold
the end of the fuse between your thumb and index finger
and pull straight out. Be
sure
to use the correct fuse. If you ever have a
problem on the road and don’t have a spare fuse,
you can borrow one of the correct value. Just pick
some feature of your vehicle that
you can get along
without
-- like the radio or cigarette lighter -- and use
its fuse, if it is of the value you need. Replace it as
soon as you can.
