2005 PONTIAC BONNEVILLE Tire chains

Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.
If You Are Stuck: In Sand, Mud, Ice
or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as rocking
can help you get out when you are stuck, but you
must use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transaxle or other parts of the
vehicle can overheat. That could cause an
engine compartment re or other damage.
When you are stuck, spin the wheels as little
as possible. Do not spin the wheels above
35 mph (55 km/h) as shown on the
speedometer.
Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transaxle back
and forth, you can destroy your transaxle. See
Rocking Your Vehicle to Get It Out on page 4-29.
For information about using tire chains on your vehicle,
seeTire Chains on page 5-90.

Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the
tongue of the trailer so that the tongue will not drop to
the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for attaching
safety chains and do not attach them to the bumper.
Always leave just enough slack so you can turn
with your rig. And, never allow safety chains to drag on
the ground.
Trailer Brakes
Does your trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes so
you will be able to install, adjust and maintain them
properly.
Because you have anti-lock brakes, do not try to tap
into your vehicles brake system. If you do, both
brake systems will not work well, or at all.
Trailer Wiring Harness
All of the electrical circuits required for your trailer
lighting system can be accessed at the driver’s side rear
lamp connector. This connector is located under the
carpet in the rear corner of your trunk compartment.
Driving with a Trailer
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.

Check Tire Pressure System
The check tire pressure system can alert you to a
large change in the pressure of one tire. The system
will not alert you before you drive that a tire is low or
at. You must begin driving before the system will
work properly.
The CHECK TIRE PRESSURE message will appear on
the Driver Information Center (DIC) or the system
monitor TIRE PRESS light will come on if pressure
difference (low pressure) is detected in one tire.
The check tire pressure system may not alert you if:
More than one tire is low.
The vehicle is moving faster than
65 mph (105 km/h).
The system is not yet calibrated.
The compact spare tire is installed.
The tire treadwear is uneven.
Tire chains are being used.
The vehicle is being driven on a rough or
frozen road.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-42.The check tire pressure system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a
low tire — but it does not replace normal tire
maintenance. SeeTires on page 5-74.
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center (DIC) or the systems
monitor TIRE PRESS light comes on, you should
stop as soon as you can and check all your tires for
damage. If a tire is at, seeIf a Tire Goes Flat on
page 5-92. Also check the tire pressure in all four tires
as soon as you can. SeeInation - Tire Pressure
on page 5-80.
Any time you adjust a tire’s pressure or have one or
more tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will
also need to reset the system whenever you rotate
the tires, buy new tires and install or remove the
compact spare.
Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
{CAUTION:
If your vehicle has P235/55R17 or P235/50R18
size tires, do not use tire chains, there is not
enough clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause damage
to the brakes, suspension or other vehicle
parts. The area damaged by the tire chains
could cause you to lose control of your vehicle
and you or others may be injured in a crash.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it is contacting your vehicle, and do
not spin your wheels.
If you do nd traction devices that will t,
install them on the front tires.
5-90

Notice:If your vehicle has a tire size other than
P235/55R17 or P235/50R18 size tires, use tire chains
only where legal and only when you must. Use
only SAE Class “S” type chains that are the proper
size for your tires. Install them on the front tires
and tighten them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions. If you can hear
the chains contacting your vehicle, stop and
retighten them. If the contact continues, slow down
until it stops. Driving too fast or spinning the
wheels with chains on will damage your vehicle.
Accessory Inator
If your vehicle has an accessory inator, it is located in
the trunk. The accessory inator will work only with
the ignition on.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate any object only to its recommended
pressure.
Pressing the AIR button will activate the inator for
10 minutes.
Notice:If you run the accessory inator longer
than 30 minutes at a time, you could damage
the inator. The repairs would not be covered by
your warranty. Run the inator for short periods of
time only.
The accessory inator comes with a kit that includes a
20-foot (6.1 m) hose and an air pressure gage, as
well as instructions and special adapters for inating
things like an air mattress or a basketball.

After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure
your spare tire is correctly inated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can nish your trip and have your full-size
tire repaired or replaced where you want. You must
calibrate the Check Tire Pressure System after installing
or removing the compact spare. SeeCheck Tire
Pressure System on page 5-83. Of course, it’s best to
replace your spare with a full-size tire as soon as
you can. Your spare will last longer and be in good
shape in case you need it again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact spare can
get caught on the rails. That can damage the tire and
wheel, and maybe other parts of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t t. Keep your compact
spare tire and its wheel together.
Notice:Tire chains will not t your compact spare.
Using them can damage your vehicle and can
damage the chains too. Do not use tire chains on
your compact spare.Appearance Care
Cleaning products can be hazardous. Some are toxic.
Other cleaning products can burst into ames if a match
is struck near them or if they get on a hot part of the
vehicle. Some are dangerous if their fumes are inhaled
in a closed space. When anything from a container
is used to clean the vehicle, be sure to follow the
manufacturer’s warnings and instructions. Always open
the doors or windows of the vehicle when cleaning
the inside.
Never use these to clean the vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous — some more than
others — and they can all damage the vehicle, too.
