2005 Buick Terraza Owner ManualM

Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or
other aftermarket equipment if your vehicle has
the passenger sensing system. SeeAdding Equipment
to Your Airbag-Equipped Vehicle on page 1-67for
more information about modications that can affect
how the system operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat cushion
and seatback may interfere with the proper
operation of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key
is turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are close
to an airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.

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 speed, fast or slow,
for the rst 500 miles (805 km). Do not make
full-throttle starts.
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 more information.
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.
2-30

If you cannot shift out of PARK (P), ease pressure on
the shift lever — 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
Shifting Out of Park (P) on page 2-39.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not 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 will not move, even
when you are on fairly level ground, always
set your parking brake and move the shift
lever to PARK (P). SeeShifting Into Park (P)
on page 2-38. If you are pulling a trailer, see
Towing a Trailer on page 4-39.REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transaxle.
The repairs would not be covered by your warranty.
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, seeIf
Your Vehicle is Stuck in Sand, Mud, Ice or Snow
on page 4-31.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{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.
2-34

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 3-25for 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).
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
2-35

Parking Brake
The parking brake is
located under the
instrument panel on the
driver’s side of the
vehicle.
To set the parking brake, hold the regular brake pedal
down with your right foot and push down on the parking
brake pedal with your left foot.
If the ignition is on, the brake system warning light will
come on. SeeBrake System Warning Light on
page 3-37.To release the parking brake, hold the regular brake
pedal down with your right foot while you push down on
the parking brake pedal with your left foot. When you
lift your left foot from the parking brake pedal, it will pop
up to the released position.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-39.

It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly 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 will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-39.
1. Hold the brake pedal down with your right foot and
set the parking brake with your left foot.
2. Move the shift lever into PARK (P) by pulling the
shift lever toward you and moving it up as far as it
will go.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle could
move suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine

parking brake is rmly set before you leave it. After you
move the shift lever into PARK (P), hold the regular
brake pedal down. Then, see if you can move the
shift lever away from PARK (P) without rst pulling it
toward you. If you can, it means that the shift lever was
not fully locked into PARK (P).
