2007 BUICK TERRAZA ECU

Accessory Power Outlet(s)
Your vehicle may be equipped with a front
accessory power outlet located below the climate
controls on the instrument panel. It can be
used to plug in electrical equipment such as a
cellular telephone or CB radio.
Pull the cover down to use the accessory power
outlet. When not in use, keep the cover on.
The rear accessory power outlet is located on the
rear compartment on the driver’s side.
To remove the cover, pull the tab on the cover
and pull it off. To put the cover back on, line up
the tabs at the back of the cover and put the
cover in place. Push down the tab to secure the
cover. When not in use, always cover the rear
accessory power outlet with the protective cap.
Notice:Leaving electrical equipment on
for extended periods will drain the battery.
Always turn off electrical equipment when
not in use and do not plug in equipment that
exceeds the maximum amperage rating of
20 amperes.Certain electrical accessories may not be
compatible with the accessory power outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem see your dealer for
additional information on accessory power outlets.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should.
The repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.

If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s airbag or airbags
are enabled (may inate).
{CAUTION:
If the on indicator comes on when you
have a rear-facing child restraint installed
in the right front passenger’s seat, it means
that the passenger sensing system has not
turned off the passenger’s frontal airbag
and seat-mounted side impact airbag
(if equipped). A child in a rear-facing child
restraint can be seriously injured or killed if
the right front passenger’s airbag inates.
This is because the back of the rear-facing
child restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag and side impact
airbag (if equipped) if the system detects
a rear-facing child restraint, no system is
fail-safe, and no one can guarantee that an
airbag will not deploy under some unusual
circumstance, even though it is turned off.
We recommend that rear-facing child
restraints be secured in the rear seat,
even if the airbag is off.

{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become
so hot that it catches re. You or others
could be burned. Check your oil as
soon as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some
winter outer clothing, a small shovel, a ashlight, a
red cloth, and a couple of reective warning
triangles. And, if you will be driving under severe
conditions, include a small bag of sand, a
piece of old carpet, or a couple of burlap bags to
help provide traction. Be sure you properly
secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where the tires
meet the road probably have good traction.
However, if there is snow or ice between the tires
and the road, you can have a very slippery
situation. You will have a lot less traction, or grip,
and will need to be very careful.What is the worst time for this? Wet ice. Very cold
snow or ice can be slick and hard to drive on.
But wet ice can be even more trouble because it
may offer the least traction of all. You can get
wet ice when it is about freezing, 32°F (0°C), and
freezing rain begins to fall. Try to avoid driving
on wet ice until salt and sand crews can get there.
Whatever the condition — smooth ice, packed,
blowing, or loose snow — drive with caution.

{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
If you put things inside your vehicle — like
suitcases, tools, packages, or anything else, they
will go as fast as the vehicle goes. If you have
to stop or turn quickly, or if there is a crash, they
will keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.

Look in the following chart to nd the maximum trailer weight for your vehicle.
Vehicle Axle RatioMaximum Trailer
Weight *GCWR
Two-Wheel-Drive 3.29 3,500 lbs (1 588 kg) 8,500 lbs (3 856 kg)
Any vehicle without the V92 trailering package or heavy-duty cooling package is limited to a 2,000 lb (907 kg) trailer
rating and a 7,000 lb (3 175 kg) GCWR.
*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and
trailer including any passengers, cargo, equipment and conversion. The GCWR for your vehicle should not be
exceeded.
You can ask your dealer for our trailering
information or advice, or you can contact the
Customer Assistance Center. SeeCustomer
Assistance Offices on page 530for more
information.

1908 Colonel Sam Drive
Oshawa, Ontario L1H 8P7Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total
or gross weight of your vehicle. The Gross Vehicle
Weight (GVW) includes the curb weight of the
vehicle, any cargo you may carry in it, and
the people who will be riding in the vehicle. If you
have a lot of options, equipment, passengers,
or cargo in your vehicle, it will reduce the tongue
weight your vehicle can carry, which will also
reduce the trailer weight your vehicle can tow. And
if you will tow a trailer, you must add the tongue
load to the GVW because your vehicle will be
carrying that weight, too. SeeLoading Your
Vehicle on page 378for more information about
your vehicle’s maximum load capacity.
388

Towing a trailer requires a certain amount of
experience. Before setting out for the open road,
you will want to get to know your rig. Acquaint
yourself with the feel of handling and braking with
the added weight of the trailer. And always
keep in mind that the vehicle you are driving is
now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector,
lamps, tires, and mirror adjustment. If the
trailer has electric brakes, start your vehicle and
trailer moving and then apply the trailer brake
controller by hand to be sure the brakes are
working. This lets you check your electrical
connection at the same time.
During your trip, check occasionally to be sure
that the load is secure, and that the lamps and any
trailer brakes are still working.Following Distance
Stay at least twice as far behind the vehicle ahead
as you would when driving your vehicle without
a trailer. This can help you avoid situations
that require heavy braking and sudden turns.
Passing
You will need more passing distance up ahead
when you are towing a trailer. And, because
you are a good deal longer, you will need to go
much farther beyond the passed vehicle
before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one
hand. Then, to move the trailer to the left,
just move that hand to the left. To move the trailer
to the right, move your hand to the right. Always
back up slowly and, if possible, have someone
guide you.
