2-3 Power Windows (If Equipped)
The window switches located on the driver's door
armrest operate both the driver's and the passenger's
windows. The passenger door has an individual window
switch for that door only.
The power windows will work when the ignition has
been turned to ACCESSORY or RUN.
Press the rear of the switch to lower the window.
Press the front of the switch to raise the window.
The driver's window also has an express
-down feature
that allows the window to be lowered without holding
the switch. Press and hold AUTO for one second to
activate the express
-down mode. The express-down
mode can be canceled at any time by pressing the
opposite side of the switch. To open the window
partway, lightly tap the switch until the window is at
the desired position.

Keys
CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be badly injured or even killed.
They could operate the power windows or other
controls or even make the vehicle move. Don't
leave the keys in a vehicle with children.

2-5
Your vehicle has one
double
-sided key for the
ignition and the door locks.
If you ever lose your key, your dealer will be able to
assist you with obtaining a new one.NOTICE:
Your vehicle has a number of new features that
can help prevent theft. You can have a lot of
trouble getting into your vehicle if you ever lock
your key inside. You may even have to damage
your vehicle to get in. So be sure you have an
extra key.
If you ever do get locked out of your vehicle, call the
GM Roadside Assistance Center. See ªRoadside
Assistanceº in the Index.

2-8
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement or
transmitter resynchronization is necessary. See the
instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
(UNLOCK): To unlock
the driver's door, press the
UNLOCK button. The
interior lamps will come
on for 40 seconds or until
the ignition is turned on. If
you press the UNLOCK
button again within five
seconds, the passenger
door will unlock.
(LOCK): Press the LOCK button to lock both doors.
The interior lamps will come on for two seconds as soon
as all the doors are closed. If you press the LOCK button
twice the horn will chirp to confirm that the doors have
locked. This will only occur if the transmitter has been
programmed with the ignition off.
If you do not want the horn to chirp as a confirmation
that the doors have locked or unlocked, consult
your dealer.

2-11 Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition. If you have an automatic transmission, taking
your key out also locks your transmission. Also
remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still 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
glove box.
If your vehicle has a remote keyless entry system,
take the transmitter with you.

Lock all the doors except the driver's.
Passlock
Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will
go off approximately five seconds after the key is
turned to RUN.
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 START
as soon as the engine starts.
If the engine is running 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 fuses. See ªFuses
and Circuit Breakersº in the Index. See your dealer
for service.

2-12
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the
long run if you follow these guidelines:

Keep your speed at 55 mph (88 km/h) or
less for the first 500 miles (805 km).

Don't drive at any one speed
-- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in. See
ªTowing a Trailerº in the Index for more
information.
Ignition Positions
With the key in the ignition you can turn it to
five different positions.
A (ACCESSORY): This position lets you use things
like the radio, power windows and the windshield
wipers when the engine is off. Push in the key and turn
it toward you. Your steering wheel will remain locked,
just as it was before you inserted the key.

2-13
B (LOCK): This position locks your ignition, steering
wheel and transmission. It's a theft
-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.
C (OFF): This position lets you turn off the engine, but
still turn the steering wheel. It doesn't lock the steering
wheel like the LOCK position. Use OFF if you must
have your vehicle in motion while the engine is off (for
example, if your vehicle is being pushed).
D (RUN): This is the position for driving.
E (START): This position starts your engine.CAUTION:
On manual transmission vehicles, turning the key
to LOCK will lock the steering column and result
in a loss of ability to steer the vehicle. This could
cause a collision. If you need to turn the engine
off while the vehicle is moving, turn the key only
to OFF. Don't press the key release button while
the vehicle is moving.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. Turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.

2-14 Key Release Button (Manual Transmission)
The ignition key cannot be
removed from the ignition
of manual transmission
vehicles unless the key
release button is used.
To remove the key, turn the key to OFF, press and hold
the button and turn the key to LOCK. Do not hold the
button in while turning the key to OFF.
Starting Your Gasoline Engine
If you have a diesel engine, see ªStarting Your Diesel
Engineº in the Diesel Engine Supplement.
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position
-- that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
NOTICE:
Don't try to shift to PARK (P) if your vehicle is
moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.

2-15 Manual Transmission
The gear selector should be in neutral and the parking
brake engaged. Hold the clutch pedal to the floor and
start the engine. Your vehicle won't start if the clutch
pedal is not all the way down
-- that's a safety feature.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start within 10 seconds, push the
accelerator pedal all the way to the floor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.When starting your engine in very cold weather
(below 0
F or
-18
C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of the key.
2. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the vehicle
starts briefly but then stops again, do the same
thing, but this time keep the pedal down for five or
six seconds. This clears the extra gasoline from
the engine.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
