brake PONTIAC G6 2007 Service Manual

Remember, unless you have ABS, if you brake so
hard that your wheels stop rolling, you will just
slide. Brake so your wheels always keep rolling
and you can still steer.
Whatever your braking system, allow greater
following distance on any slippery road.
Watch for slippery spots. The road might be
ne until you hit a spot that is covered with
ice. On an otherwise clear road, ice patches
may appear in shaded areas where the
sun cannot reach, such as around clumps of
trees, behind buildings, or under bridges.
Sometimes the surface of a curve or an
overpass may remain icy when the
surrounding roads are clear. If you see a
patch of ice ahead of you, brake before you
are on it. Try not to brake while you are
actually on the ice, and avoid sudden steering
maneuvers.
If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could be in
a serious situation. You should probably stay
with your vehicle unless you know for sure that you
are near help and you can hike through the
snow. Here are some things to do to summon
help and keep yourself and your passengers safe:
Turn on your hazard ashers.
Tie a red cloth to your vehicle to alert police
that you have been stopped by the snow.
Put on extra clothing or wrap a blanket
around you. If you do not have blankets
or extra clothing, make body insulators from
newspapers, burlap bags, rags, oor
mats — anything you can wrap around
yourself or tuck under your clothing to
keep warm.

For vehicles that can be dinghy towed with all
four wheels on the ground, follow these steps:
1. Position the vehicle to tow and then secure it.
2. Turn the ignition to OFF.
3. Set the parking brake.
4. To prevent your battery from draining while
the vehicle is being towed, remove the
following fuse from the instrument panel fuse
block: (IGN SENSOR). SeeInstrument
Panel Fuse Block on page 416for more
information.5. Turn the ignition to ACC.
6. Shift your transaxle to NEUTRAL (N).
7. Release the parking brake.
Notice:If you exceed 65 mph (105 km/h) while
towing your vehicle, it could be damaged.
Never exceed 65 mph (105 km/h) while towing
your vehicle.
Notice:Towing your vehicle from the rear
could damage it. Also, repairs would not
be covered by the warranty. Never have your
vehicle towed from the rear.

Dolly Towing
To tow your vehicle with two wheels on the
ground and a dolly, do the following:
1. Put the front wheels on a dolly.
2. If you have an automatic transaxle, shift the
transaxle to PARK (P). If you have a manual
transaxle, shift the vehicle to SECOND (2).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight-ahead
position with a clamping device designed for
towing.
5. Release the parking brake.
Towing a Trailer
{CAUTION:
If you do not use the correct equipment
and drive properly, you can lose control
when you pull a trailer. For example, if the
trailer is too heavy, the brakes may not
work well — or even at all. You and your
passengers could be seriously injured.
You may also damage your vehicle; the
resulting repairs would not be covered by
your warranty. Pull a trailer only if you
have followed all the steps in this section.
Ask your dealer for advice and
information about towing a trailer with
your vehicle.
Your vehicle can tow a trailer if it is equipped with
the proper trailer towing equipment. To identify
the trailering capacity of your vehicle, you should
read the information in “Weight of the Trailer”
that appears later in this section. Trailering
is different than just driving your vehicle by itself.
296

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 at the rear edge
of the driver’s door or seeLoading Your Vehicle on
page 288. 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’ll 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 140. Dirt and water can, too.
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. And because
you may have anti-lock brakes, do not try to
tap into your vehicle’s brake system. If you do,
both systems will not work well, or at all.
300

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.
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’re
a good deal longer, you’ll 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.
301

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.
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. 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.
Driving On Grades
When towing a trailer on long uphill grades and
the outside temperature is above 85°F (29°C),
reduce your vehicle speed to 45 mph (72 km/h) to
avoid overheating the engine cooling system.
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.
302

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
PARK (P) for an automatic transaxle or into
gear for a manual transaxle. When parking
uphill, turn your wheels away from the
curb. When parking downhill, turn your wheels
into the curb.
2. Have someone place chocks under the trailer
wheels.
3. When the 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 shift into PARK (P).
5. Release the regular brakes.
303

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, and
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 are pulling a trailer. See the Maintenance
Schedule for more on this. Things that are
especially important in trailer operation are
automatic transaxle uid (do not overll), engine
oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and
the Index will help you nd them quickly. If you
are trailering, it is 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 342.
