See your dealer or a locksmith who can service the
PASS
-Key II to have a new key made.
If you're ever driving and the SECURITY light comes
on and stays on, you will be able to restart your engine if
you turn it off. Your PASS
-Key II system, however, 
is not working properly and must be serviced by your
dealer. Your vehicle is not protected by the 
PASS
-Key II system.
If you lose or damage a PASS
-Key II ignition key, see
your dealer or a locksmith who can service PASS
-Key II
to have a new key made. In an emergency, call the 
Buick Premium Roadside Assistance Center at
1
-800-252-1112. In Canada, call 1-800-268-6800.
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:
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.

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transaxle Operation
Your automatic transaxle has a shift lever located on the
steering column.
PARK (P): This position locks your front wheels. 
It's the best position to use when you start your engine
because your vehicle can't move easily.
CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
See ªShifting Into PARK (P)º in the Index. If
you're pulling a trailer, see ªTowing a Trailerº in
the Index.

Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has a Brake
-Transaxle
Shift Interlock (BTSI). You have to fully apply your
regular brakes before you can shift from PARK (P)
when the ignition key is in RUN. If you cannot shift out
of PARK (P), ease pressure on the shift lever and push
the shift lever all the way into PARK (P) as you
maintain brake application. Then move the shift lever
into the gear you wish. See ªShifting Out of PARK (P)º
in the Index.
REVERSE (R): Use this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle is
moving forward could damage your transaxle.
Shift to REVERSE (R) only after your vehicle 
is stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transaxle, see
ªStuck: In Sand, Mud, Ice or Snowº in the Index.NEUTRAL (N): In this position, your engine doesn't
connect with the wheels. To restart when you're 
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is ªracingº (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people or
objects. Don't shift out of PARK (P) or
NEUTRAL (N) while your engine is racing.
NOTICE:
Damage to your transaxle caused by shifting out
of PARK (P) or NEUTRAL (N) with the engine
racing isn't covered by your warranty.

AUTOMATIC OVERDRIVE (): This position is for
normal driving. If you need more power for passing, 
and you're:
Going less than about 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'll shift down to the next gear and have more power.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE ().
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE ():
When driving on hilly, winding roads
When towing a trailer, so there is less shifting
between gears
When going down a steep hill
SECOND (2): This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you would
also want to use your brakes off and on.
NOTICE:
Don't drive in SECOND (2) for more than 
5 miles (8 km), or at speeds over 55 mph 
(90 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE () or 
THIRD (3) as much as possible.
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h), or you can
damage your engine.
FIRST (1): This position gives you even more power
(but lower fuel economy) than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. 
If the selector lever is put in FIRST (1), the transaxle
won't shift into first gear until the vehicle is going
slowly enough.

NOTICE:
If your front wheels can't rotate, don't try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into PARK (P)
to hold your vehicle in position on a hill.
Parking Brake
This vehicle has a PUSH
TO RELEASE parking
brake pedal. To set the
parking brake, hold the
regular brake pedal down
with your right foot. Push
down the parking brake
pedal with your left foot.If the ignition is on, the brake system warning light will
turn on and a single chime will be heard. The parking
brake uses the brakes on the rear wheels.
To release the parking brake, hold the regular brake
pedal down and push the parking brake pedal with your
left foot. This will release the parking brake pedal.
When you lift your left foot, the park brake pedal will
follow it to the released position.
If you try to drive approximately 40 feet (12.2 m) with
the parking brake on, the brake light stays on and a
chime sounds until you release the parking brake.
NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You may have to
replace them, and you could also damage other
parts of your vehicle.
If you are towing a trailer and are parking on any hill,
see ªTowing a Trailerº in the Index. That section
explains what to do first to keep the trailer from moving.

Shifting Into PARK (P)
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll. 
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure your vehicle won't move, 
even when you're on fairly level ground, use the
steps that follow. If you're pulling a trailer, see
ªTowing a Trailerº in the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) like this:
Pull the lever toward you.
