PONTIAC G8 2008 Owners Manual

Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
2,000 lbs (907 kg). But even
that can be too heavy.
It depends on how you plan to use
your rig. For example, speed,
altitude, road grades, outside
temperature and how much your
vehicle is used to pull a trailer are all
important. It can also depend on
any special equipment that you have
on your vehicle, and the amount
of tongue weight the vehicle
can carry. See “Weight of the Trailer
Tongue” later in this section for
more information.
Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers and cargo in
the tow vehicle must be subtracted
form the maximum trailer weight.You can ask your dealer/retailer for
our trailering information or
advice, or you can write us at our
Customer Assistance Offices.
SeeCustomer Assistance Offices
on page 12-4for more information.
Weight 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 tow a trailer, you
must add the tongue load to the
GVW because your vehicle will be
carrying that weight, too. SeeLoading the Vehicle on page 8-28
for more information about your
vehicle’s maximum load capacity.
If you are using a weight-carrying
hitch, the trailer tongue (A)
should weigh 10 to 15 percent of
the total loaded trailer weight (B).
After you have loaded your
trailer, weigh the trailer and then the
tongue, separately, to see if the
weights are proper. If they are not,
you may be able to get them
right simply by moving some items
around in the trailer.

Total Weight on Your Vehicle’s
Tires
Be sure your vehicle’s tires are
inated to the upper limit for cold
tires. You will nd these numbers on
the Tire-Loading Information label.
SeeLoading the Vehicle on
page 8-28. Then be sure you do not
go over the GVW limit for your
vehicle, including the weight of the
trailer tongue.
Hitches
It is important to have the correct
hitch equipment. Crosswinds,
large trucks going by and rough
roads are a few reasons why
you will need the right hitch. Here
are some rules to follow:
The rear bumper on your vehicle
is not intended for hitches. Do
not attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch
that does not attach to the
bumper.
Will you have to make any holes
in the body of your vehicle when
you install a trailer hitch? If you
do, then be sure to seal the holes
later when you remove the hitch.
If you do not seal them, deadly
carbon monoxide (CO) from your
exhaust can get into your vehicle.
SeeEngine Exhaust on
page 8-12. Dirt and water can
also enter the vehicle.
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. Alwaysleave 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 tap into your vehicle’s 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 on
the rear corner of the 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.
Towing with the Electronic
Stability Program (ESP®)
When towing, the sound of the ESP
modulator might be heard. The
ESP is reacting to the vehicle
movement caused by the trailer,
which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as when driving
your vehicle without a trailer. This
can help avoid situations that require
heavy braking and sudden turns.
Passing
More passing distance is needed up
ahead when you are towing a
trailer. And, because the vehicle is
longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the 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 the hand to
the right. Always back up slowly
and, if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause
the trailer to come in contact with
the vehicle. Your vehicle could
be damaged. Avoid making
very sharp turns while trailering.
When you are turning with a
trailer, make wider turns than
normal. Do this so your trailer will
not strike soft shoulders, curbs, road
signs, trees or other objects.
Avoid jerky or sudden maneuvers.
Signal well in advance.
Vehicle Service and Care 9-89
2008 - Pontiac G8 Owner Manual

Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle
may need a different turn signal
asher and/or extra wiring. Check
with your dealer/retailer. The arrows
on your instrument panel will
ash whenever you signal a turn or
lane change. Properly hooked
up, the trailer lamps will also ash,
telling other drivers you are
about to turn, change lanes or stop.
When towing a trailer, the arrows
on your instrument panel will
ash for turns even if the bulbs on
the trailer are burned out. Thus, you
may think drivers behind you are
seeing your signal when they
are not. It is important to check
occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning
lights. When you plug a trailer
lighting system into your vehicle’s
lighting system, its bulb warning
lights may not let you know if one of
your lamps goes out. So, whenyou have a trailer lighting system
plugged in, be sure to check
your vehicle and trailer lamps from
time to time to be sure they are
all working. Once you disconnect the
trailer lamps, the bulb warning
lights again can tell you if one of
your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower
gearbeforeyou start down a
long or steep downgrade. If you do
not shift down, you might have
to use your brakes so much
that they would get hot and no
longer work well.
On a long uphill grade, shift down to
a lower gear and reduce your
speed to around 45 mph (70 km/h)
to reduce the possibility of engine
and transmission overheating.
Parking on Hills
{CAUTION
You really should not park your
vehicle, with a trailer attached,
on a hill. If something goes
wrong, your rig could start to
move. People can be injured,
and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig
on a hill, here is how to do it:
1. Apply your regular brakes, but do
not shift into P (Park) yet.
2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in
place, release the regular
brakes until the chocks absorb
the load.
4. Reapply the regular brakes.
Then apply your parking
brake, and then shift to P (Park).
5. Release the regular brakes.
9-90 Vehicle Service and Care
2008 - Pontiac G8 Owner Manual

When You Are Ready to Leave
After Parking on a Hill
1. Apply your regular brakes and
hold the pedal down while you:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is
clear of the chocks.
4. Stop and have someone pick up
and store the chocks.
Maintenance When Trailer
Towing
Your vehicle will need service more
often when you’re pulling a trailer.
See the Maintenance Schedule for
more on this. Things that are
especially important in trailer
operation are automatic transmission
uid (don’t overll), engine oil, drivebelt, cooling system and brake
system. Each of these is covered in
this manual, and the Index will help
you nd them quickly. If you’re
trailering, it’s a good idea to review
this information before you start
your trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
Your cooling system may
temporarily overheat during severe
operating conditions. SeeEngine
Overheating on page 9-16.
Appearance Care
Interior Cleaning
Your vehicle’s interior will continue
to look its best if it is cleaned
often. Although not always visible,
dust and dirt can accumulate
on your upholstery. Dirt can damage
carpet, fabric, leather, and plastic
surfaces. Regular vacuuming
is recommended to remove particles
from the upholstery. It is important
to keep your upholstery from
becoming and remaining heavily
soiled. Soils should be removed as
quickly as possible. Your vehicle’s
interior may experience extremes of
heat that could cause stains to
set rapidly.
Lighter colored interiors may require
more frequent cleaning. Use care
because newspapers and garments
that transfer color to your home
furnishings may also transfer color
to your vehicle’s interior.
Vehicle Service and Care 9-91
2008 - Pontiac G8 Owner Manual

When cleaning your vehicle’s
interior, only use cleaners
specically designed for the
surfaces being cleaned. Permanent
damage may result from using
cleaners on surfaces for which they
were not intended. Use glass
cleaner only on glass. Remove any
accidental over-spray from other
surfaces immediately. To prevent
over-spray, apply cleaner directly to
the cleaning cloth.
Notice:If you use abrasive
cleaners when cleaning glass
surfaces on your vehicle,
you could scratch the glass
and/or cause damage to the rear
window defogger. When
cleaning the glass on your
vehicle, use only a soft cloth and
glass cleaner.Many cleaners contain solvents that
may become concentrated in
your vehicle’s breathing space.
Before using cleaners, read
and adhere to all safety instructions
on the label. While cleaning your
vehicle’s interior, maintain adequate
ventilation by opening your
vehicle’s doors and windows.
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Your dealer/retailer has a product
for cleaning your vehicle’s glass.
You can also obtain a product from
your dealer/retailer to remove
odors from your vehicle’s upholstery.
Do not clean your vehicle using
the following cleaners or techniques:
Never use a knife or any other
sharp object to remove a soil
from any interior surface.
Never use a stiff brush. It can
cause damage to your vehicle’s
interior surfaces.
Never apply heavy pressure or
rub aggressively with a cleaning
cloth. Use of heavy pressure
can damage the interior and does
not improve the effectiveness
of soil removal.
Use only mild, neutral-pH soaps.
Avoid laundry detergents or
dishwashing soaps with
degreasers. Using too much soap
will leave a residue that leaves
streaks and attracts dirt. For liquid
cleaners, about 20 drops per
gallon (3.78 L) of water is a
good guide.
Do not heavily saturate the
upholstery while cleaning.
Damage to your vehicle’s interior
may result from the use of many
organic solvents such as naptha,
alcohol, etc.

Fabric/Carpet
Use a vacuum cleaner with a soft
brush attachment frequently to
remove dust and loose dirt. A
canister vacuum with a beater bar in
the nozzle may only be used on oor
carpet and carpeted oor mats. For
soils, always try to remove them rst
with plain water or club soda. Before
cleaning, gently remove as much of
the soil as possible using one of the
following techniques:
For liquids: gently blot the
remaining soil with a paper towel.
Allow the soil to absorb into the
paper towel until no more can be
removed.
For solid dry soils: remove as
much as possible and then
vacuum.
To clean, use the following
instructions:
1. Saturate a lint-free, clean white
cloth with water or club soda.
2. Wring the cloth to remove excess
moisture.3. Start on the outside edge of the
soil and gently rub toward the
center. Continue cleaning, using
a clean area of the cloth each
time it becomes soiled.
4. Continue to gently rub the soiled
area until the cleaning cloth
remains clean.
5. If the soil is not completely
removed, use a mild soap
solution and repeat the cleaning
process that was used with
plain water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. When
a commercial upholstery cleaner or
spot lifter is to be used, test a
small hidden area for colorfastness
rst. If the locally cleaned area
gives any impression that a
ring formation may result, clean the
entire surface.
After the cleaning process has been
completed, a paper towel can be
used to blot excess moisture
from the fabric or carpet.
Leather
A soft cloth dampened with water
can be used to remove dust. If
a more thorough cleaning is
necessary, a soft cloth dampened
with a mild soap solution can
be used. Allow the leather to dry
naturally. Do not use heat to
dry. Never use steam to clean
leather. Never use spot lifters or
spot removers on leather. Many
commercial leather cleaners
and coatings that are sold to
preserve and protect leather may
permanently change the appearance
and feel of your leather and are
not recommended. Do not use
silicone or wax-based products, or
those containing organic solvents to
clean your vehicle’s interior
because they can alter the
appearance by increasing the gloss
in a non-uniform manner. Never
use shoe polish on leather.

Instrument Panel, Vinyl, and
Other Plastic Surfaces
A soft cloth dampened with water
may be used to remove dust.
If a more thorough cleaning is
necessary, a clean soft cloth
dampened with a mild soap solution
can be used to gently remove
dust and dirt. Never use spot lifters
or removers on plastic surfaces.
Many commercial cleaners
and coatings that are sold to
preserve and protect soft plastic
surfaces may permanently change
the appearance and feel of your
interior and are not recommended.
Do not use silicone or wax-based
products, or those containing
organic solvents to clean your
vehicle’s interior because they can
alter the appearance by increasing
the gloss in a non-uniform manner.Some commercial products may
increase gloss on your instrument
panel. The increase in gloss may
cause annoying reections in the
windshield and even make it difficult
to see through the windshield under
certain conditions.
Exterior Cleaning
Cleaning Exterior
Lamps/Lenses
Use only lukewarm or cold water, a
soft cloth and a car washing
soap to clean exterior lamps and
lenses. Follow instructions
under “Washing Your Vehicle” later
in this section.
Finish Care
Occasional waxing or mild polishing
of your vehicle by hand may be
necessary to remove residue from
the paint nish. You can get
approved cleaning products from
your dealer/retailer. SeeVehicle
Care/Appearance Materials
on page 9-99.
If your vehicle has a
basecoat/clearcoat paint nish, the
clearcoat gives more depth and
gloss to the colored basecoat.
Always use waxes and polishes that
are non-abrasive and made for a
basecoat/clearcoat paint nish.
Notice:Machine compounding
or aggressive polishing on a
basecoat/clearcoat paint nish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint nish on your
vehicle.
9-94 Vehicle Service and Care
2008 - Pontiac G8 Owner Manual

Foreign materials such as calcium
chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals
from industrial chimneys, etc., can
damage your vehicle’s nish if
they remain on painted surfaces.
Wash the vehicle as soon as
possible. If necessary, use
non-abrasive cleaners that are
marked safe for painted surfaces to
remove foreign matter.
Exterior painted surfaces are subject
to aging, weather and chemical
fallout that can take their toll over a
period of years. You can help to keep
the paint nish looking new by
keeping your vehicle garaged or
covered whenever possible.Protecting Exterior Bright Metal
Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Wash with water or
use chrome polish on chrome or
stainless steel trim, if necessary.
Use special care with aluminum trim.
To avoid damaging protective trim,
never use auto or chrome polish,
steam or caustic soap to clean
aluminum. A coating of wax, rubbed
to high polish, is recommended for all
bright metal parts.
Washing Your Vehicle
The best way to preserve your
vehicle’s nish is to keep it clean by
washing it often.
Do not wash the vehicle in direct
sunlight. Use a car washing soap.Notice:Certain cleaners contain
chemicals that can damage the
emblems or nameplates on your
vehicle. Check the cleaning
product label. If it states that it
should not be used on plastic
parts, do not use it on your vehicle
or damage may occur and it would
not be covered by the warranty.
Do not use cleaning agents that are
petroleum based or that contain
acid or abrasives, as they can
damage the paint, metal or plastic
on your vehicle. Approved cleaning
products can be obtained from
your dealer/retailer. SeeVehicle
Care/Appearance Materials on
page 9-99. Follow all manufacturers’
directions regarding correct
product usage, necessary safety
precautions and appropriate
disposal of any vehicle care product.
Vehicle Service and Care 9-95
2008 - Pontiac G8 Owner Manual

Rinse the vehicle well, before
washing and after to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the nish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and
water spotting.
High pressure car washes may
cause water to enter the vehicle.
Avoid using high pressure washes
closer than 12 inches (30 cm) to the
surface of the vehicle. Use of power
washers exceeding 1,200 psi (8 274)
can result in damage or removal of
paint and decals.
Notice:Conveyor systems on
some automatic car washes could
damage the vehicle. There may
not be enough clearance for
the undercarriage. Check with the
car wash manager before using
the automatic car wash.Weatherstrips
Silicone grease on weatherstrips will
make them last longer, seal better,
and not stick or squeak. Apply
silicone grease with a clean cloth.
During very cold, damp weather
frequent application may be required.
See “Fluids and Lubricants” in the
Index of the “Maintenance and
Warranty and Owner assistance
Information” manual.
Wheels and Trim — Aluminum
or Chrome
Your vehicle may have either
aluminum or chrome-plated wheels.
Keep the wheels clean using a soft
clean cloth with mild soap and water.
Rinse with clean water. After rinsing
thoroughly, dry with a soft clean
towel. A wax may then be applied.Notice:Chrome wheels and
other chrome trim may be
damaged if you do not wash your
vehicle after driving on roads
that have been sprayed with
magnesium, calcium or sodium
chloride. These chlorides are
used on roads for conditions
such as ice and dust. Always
wash your vehicle’s chrome with
soap and water after exposure.
Notice:If you use strong soaps,
chemicals, abrasive polishes,
cleaners, brushes, or cleaners
that contain acid on aluminum or
chrome-plated wheels, you
could damage the surface of the
wheel(s). The repairs would
not be covered by your warranty.
Use only approved cleaners on
aluminum or chrome-plated
wheels.
