trailer BUICK TERRAZA 2007 Owner's Manual

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. See
Towing a Trailer on page 386for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.

Automatic Transaxle Operation
Maximum engine speed is limited when you are in
PARK (P) or NEUTRAL (N), to protect driveline
components from improper operation.
There are several different positions for your shift
lever.
PARK (P):This gear position locks your front
wheels. It is the best position to use when you start
your engine because your vehicle cannot move
easily.
Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transaxle shift lock control system. You
must fully apply your regular brakes rst and
then press the shift lever button before you can
shift from PARK (P) when the ignition key is
in RUN. If you cannot shift out of PARK (P), easepressure on the shift lever and push the shift lever
all the way info PARK (P) as you maintain
brake application. Then press the shift lever button
and move the shift lever into another gear. See
Shifting Out of Park (P) on page 139.
{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). See
Shifting Into Park (P) on page 138.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 386.
133

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. 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.
The vehicle will shift down to the next gear
and have more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 362
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 DRIVE (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. SeeClimate
Control System on page 193andDual Climate
Control System on page 197for more information.
THIRD (3):This position is also used for normal
driving. It reduces vehicle speed more than
DRIVE (D) without using your brakes. You might
choose THIRD (3) instead of DRIVE (D) when
driving on hilly, winding roads, when towing
a trailer, so there is less shifting between gears
and when going down a steep hill.
135

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 214.
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 386.
137

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 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 386.
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
running, be sure your vehicle is in PARK (P)
and the 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).
138

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 141.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 373.
{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 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).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 138.
If you are pulling a trailer, seeTowing a Trailer on
page 386.
142

To signal a lane change, just raise or lower the
lever until the arrow starts to ash. Hold it
there until you complete your lane change. The
lever will return by itself when you release it.
As you signal a turn or a lane change, if the arrow
ashes faster than normal, a signal bulb may be
burned out and other drivers will not see your turn
signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and check
the fuse. SeeBulb Replacement on page 443and
Fuses and Circuit Breakers on page 497.
If you have a trailer towing option with added
wiring for the trailer lamps, the signal indicator will
ash at a normal rate even if a turn signal bulb
is burned out. Check the front and rear turn signal
lamps regularly to make sure they are working.
Turn Signal On Chime
If either turn signal is left on for more than
3/4 mile (1.2 km), a chime will sound to let the
driver know to turn it off. If you need to leave the
signal on for more than 3/4 mile (1.2 km), turn
off the signal and then turn it back on.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to
high beam, push the turn signal/multifunction lever
away from you.
When the high beams
are on, this light
will appear on the
instrument panel cluster.
To change the headlamps from high beam to low
beam, pull the turn signal/multifunction lever
toward you.
Flash-to-Pass
When the headlamps are off, pull the lever toward
you to momentarily turn on the high beams.
This will signal that you are going to pass. When
you release the lever, they will turn off.

The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This
is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action
may be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Battery
Voltage Low. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible.Battery Run-Down Protection
Your vehicle has a feature to help prevent you
from draining the battery, in case you accidentally
leave the interior lamps on. If you leave any
interior lamps on while the ignition is in lock or off,
they will automatically turn off after 10 minutes.
The lamps will not come back on again until
you do one of the following:
Turn the ignition to RUN or ACCESSORY
Open a closed door, or close and reopen
a door.
Turn the interior lamps on if they are in the
door or override position.
Turn the interior lamps to the door or override
position and then to on again if the interior
lamp control is in the on position.
If your vehicle has less than 15 miles (25 km)
on the odometer, the battery saver will turn off
the lamps after only three minutes.

How the System Works
Unless disabled, the URPA will turn on
automatically when the shift lever is moved into
REVERSE (R). When the system turns on, the
three lights on the display will illuminate for one and
a half seconds to let you know that the system is
working. If your vehicle is moving in REVERSE (R)
at a speed greater than 3 mph (5 km/h), the red
light will ash to remind you that the system does
not work at speed greater than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed
of less than 3 mph (5 km/h), one of the following
will occur:
Description English Metric
amber light 5 ft 1.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights &
continuous chime20 in 0.5 m
amber/amber/
red lights ashing &
continuous chime1 ft 0.3 m
A chime will sound the rst time an object
is detected between 20 inches (0.5 m) and
5 feet (1.5 m) away.URPA cannot detect objects that are above liftgate
level. In order for the rear sensors to recognize
an object, it must be within detection range behind
the vehicle.
When the System Does Not Seem to
Work Properly
The light may ash red when the vehicle is in
REVERSE (R) if the ultrasonic sensors are
not kept clean. So be sure to keep your rear
bumper free of mud, dirt, snow, ice and slush.
Other conditions that may affect system
performance include things like the vibrations from
a jackhammer or the compression of air brakes
on a very large truck. If after cleaning the
rear bumper and then driving forward at least
15 mph (25 km/h), the display continues to ash
red, see your dealer.
If a trailer was attached to your vehicle, or a
bicycle or an object was on the back of, or hanging
out of your liftgate during your last drive cycle,
the light may also ash red. The light will continue
to ash whenever in REVERSE (R) until your
vehicle is driven forward at least 15 mph (25 km/h)
without any obstructions behind the vehicle.

This may prevent more serious damage to your
vehicle. This system is also designed to assist your
service technician in correctly diagnosing any
malfunction.
Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by
your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 400.This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
