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 is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
Press UNLOCK once to
unlock the driver's door and
to turn on the interior lamps
(see ªIllumination on
Remote Activationº in the
Index for more details).
Press UNLOCK again within five seconds to unlock all
the doors. To lock all doors, press LOCK. To unlock the
trunk, press the button with the trunk symbol on the
remote keyless entry transmitter. The trunk will only
unlock if your transaxle is in PARK (P).

2-13
To replace the battery:
1. Insert a flat object like a dime into the slot on the
back of the transmitter. Gently pry apart the front
and back.
2. Remove the old battery and replace it with the new
one. (Use type CR2032 or an equivalent.) Make sure
the positive (+) side of the battery is facing down.
Do not use a metal object to remove the old battery.
3. Snap the top and bottom together, making sure the
halves are together tightly so water won't get in.4. Test the operation of the transmitter with
your vehicle. If the transmitter does not
work, try resynchronizing the transmitter.
(See ªResynchronizationº following.)
5. Resynchronize and then test the transmitter.
Resynchronization
Resynchronization may be necessary due to the
security method used by this remote keyless entry
system. The transmitter does not send the same
signal twice to the receiver. The receiver will not
respond to a signal it has previously been sent.
This prevents someone from recording and
playing back the signal from the transmitter.
To resynchronize the transmitter with the receiver,
do the following:
1. Stand close to your vehicle.
2. Simultaneously press and hold the LOCK and
UNLOCK buttons on the remote keyless entry
transmitter for about seven seconds.
There will be an audible confirmation when
resynchronization is done.
If the locks do not cycle, see your dealer for service.

PASS-Key
II
Your 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 you insert
or remove the key from
the ignition.
PASS
-Key II uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.When the PASS
-Key II system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. For about three minutes, the starter
won't work and fuel won't go to the engine. If someone
tries to start your vehicle again or uses another key
during this time, the vehicle will not start. This
discourages someone from randomly trying different
keys with different resistor pellets in an attempt to make
a match.
The ignition key must be clean and dry before it's
inserted in the ignition or the engine may not start.
If the engine does not start and the SECURITY light
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 starter still won't work, and the key appears
to be clean and dry, wait about three minutes and try
another ignition key. At this time, you may also want to
check the fuse (see ªFuses and Circuit Breakersº in the
Index). If the starter won't work with the other key, your
vehicle needs service. If your vehicle does start, the first
ignition key may be faulty. See your dealer or a
locksmith who can service the PASS
-Key II.

2-17
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work. The
SECURITY light will then come on. But you don't have
to wait three minutes before trying another ignition key.
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, 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.

Ignition Positions
With the ignition key in the ignition, you can turn the
switch to five positions:
ACCESSORY (A): The accessory position lets you use
the radio and windshield wipers when the engine is off.
To use ACC, push in the key and turn it toward you.
Your steering wheel will stay locked.
LOCK (B): Before you put the key into the ignition
switch, the switch is in LOCK. It's also the only position
from which you can remove your key. This position
locks your ignition, steering wheel and transaxle. It's a
theft
-deterrent feature.OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel. Use OFF if you must have your vehicle pushed
or towed.
RUN (D): This position is where the key returns
after you start your vehicle. With the engine off, you
can use RUN to display some of your warning and
indicator lights.
START (E): This position starts your engine.
A warning chime will sound if you open the driver's
door when the ignition is in OFF, LOCK or
ACCESSORY and the key is in the ignition.
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. But 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.

2-24
AUTOMATIC OVERDRIVE (
): This position is
for normal driving. If you need more power for passing,
and you're:

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 pedal all the way down.
You'll shift down to the next gear and have more power.
NOTICE:
If your vehicle seems to start up rather slowly,
or if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens,
have your vehicle serviced right away. Until then,
you can use SECOND (2) when you are driving
less than 35 mph (55 km/h) and AUTOMATIC
OVERDRIVE (
) for higher speeds.
THIRD (3): This position is also used for normal
driving, but 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.

When driving in no
-highway scenarios
(i.e. city streets, etc.)
SECOND (2): This position gives you more power but
lower fuel economy. 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.

2-49
Auxiliary Power Connection
(Power Drop)
Your vehicle is equipped
with an auxiliary
power connection.
It is located on the passenger's side of the vehicle,
under the glove box, and is labeled with a wire function
and fuse rating. This feature provides power, ground
and accessory wires which can be accessed to add
aftermarket electrical equipment to your vehicle.
For information on accessing the connection and
electrical hookup, please refer to your service manual.
To order a service manual, see ªService Publications,
Orderingº in the Index.
NOTICE:
Adding some electrical equipment to your vehicle
can damage it or keep other things from working
as they should. This wouldn't be covered by your
warranty. Check with your dealer before adding
electrical equipment, and never use anything that
exceeds the fuse rating.
