2006 BUICK TERRAZA service

If the engine does not start and the security message
comes on, the key may have a damaged transponder.
Turn the ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the instrument panel PASS
KEY fuse. If the engine still does not start with the
other key, your vehicle needs service. If your vehicle
does start, the rst key may be faulty. See your dealer or
a locksmith who can service the PASS-Key
®III to
have a new key made. SeeFuses and Circuit Breakers
on page 5-96.
It is possible for the PASS-Key
®III decoder to learn the
transponder value of a new or replacement key. Up
to 10 keys may be programmed for the vehicle.
This procedure is for learning additional keys only. If all
the currently programmed keys are lost or do not
operate, you must see your dealer or a locksmith who
can service PASS-Key
®III to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III to get a new key blank that is cut exactly
as the ignition key that operates the system.To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed key into the
ignition lock cylinder and start the engine. If the
engine will not start, see your dealer for service.
3. After the engine has started, turn the key to OFF
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
5. The security message will turn off once the key has
been programmed. It may not be apparent that the
security message went on due to how quickly
the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security message comes
on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III key, see your
dealer or a locksmith who can service PASS-Key®III to
have a new key made.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake, or slow, the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new
brake linings are not 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.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-39for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
The key can be turned to one of four positions while in
the ignition switch.
A (LOCK):This is the only position from which you can
remove the key. This position locks your ignition and
transaxle.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
none of this works, then your vehicle needs service.
2-32

{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
while the engine is running at high speed may
damage the transaxle. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speeds when shifting your vehicle.
AUTOMATIC OVERDRIVE (D):This position is for
normal driving. If you need more power for passing, and
you are:
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 all the way down.
You will shift down to the next gear and have more
power.Notice:If your vehicle seems to start up rather
slowly or not shift gears when you go faster, and
you continue to drive your vehicle that way, you
could damage the transaxle. Have your vehicle
serviced right away. You can drive in SECOND (2)
when you are driving less than 35 mph (55 km/h) and
AUTOMATIC OVERDRIVE (D) for higher speeds
until then.
Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35°F (2°C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed until
the engine is warmed up. This is a normal condition
designed to provide heat to the passenger compartment
and defrost the windows more quickly. SeeDual
Climate Control System on page 3-26for more
information.
THIRD (3):This position is also used for normal driving,
but it offers more power and lower fuel economy than
AUTOMATIC OVERDRIVE (D).
2-37

Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):
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:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).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 THIRD (3) for higher speeds.
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
shift lever is put in FIRST (1), the transaxle will not
downshift into rst gear until the vehicle is going slow
enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes, or parking brake to hold the vehicle
in place.

panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light comes on if there is an electrical problem. The
system check includes the airbag sensor, the airbag
modules, the wiring and the diagnostic module.
