2007 PONTIAC G5 warning light

If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can
burn you badly, even if you just open the
hood. Stay away from the engine if you
see or hear steam coming from it. Just
turn it off and get everyone away from
the vehicle until it cools down. Wait until
there is no sign of steam or coolant
before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned.
Stop your engine if it overheats, and get
out of the vehicle until the engine is cool.
Notice:If your engine catches re because
you keep driving with no coolant, your vehicle
can be badly damaged. The costly repairs
would not be covered by your warranty.
If No Steam Is Coming From Your
Engine
An engine coolant temperature warning can
indicate a serious problem. SeeEngine Coolant
Temperature Warning Light on page 167.
If you get an engine coolant temperature warning,
but see or hear no steam, the problem may not
be too serious. Sometimes the engine can
get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the engine coolant temperature warning
with no sign of steam, try this for a minute or so:
1. If you have an air conditioner and it is on, turn
it off.
2. In heavy traffic, let the engine idle in
NEUTRAL (N) for automatic transmission or
NEUTRAL for manual transmission, while
stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.

There are only two reasons why the brake uid
level in the reservoir might go down. The rst is that
the brake uid goes down to an acceptable level
during normal brake lining wear. When new linings
are put in, the uid level goes back up. The other
reason is that uid is leaking out of the brake and/or
clutch hydraulic system. If it is, you should have
the brake and/or clutch system xed, since a leak
means that sooner or later the brakes and/or clutch
will not work well, or will not work at all.
So, it is not a good idea to top off the brake/clutch
uid. Adding uid will not correct a leak. If you
add uid when the brake linings are worn, you
will have too much uid when you get new brake
linings. You should add or remove uid, as
necessary, only when work is done on the
brake/clutch hydraulic system.
{CAUTION:
If your vehicle has too much brake uid, it
can spill on the engine. The uid will burn
if the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake and/or clutch
hydraulic system.
When the brake uid falls to a low level, the brake
warning light will come on. SeeBrake System
Warning Light on page 165.

Brake Wear
Your vehicle has front disc brakes and may have
rear drum brakes or rear disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound may come and go or be heard all
the time your vehicle is moving, except when
you are pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.Some driving conditions or climates may cause a
brake squeal when the brakes are rst applied
or lightly applied. This does not mean something
is wrong with the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to GM torque
specications.
If your vehicle has rear drum brakes, they do not
have wear indicators, but if you ever hear a rear
brake rubbing noise, have the rear brake linings
inspected immediately. Also, the rear brake drums
should be removed and inspected each time the
tires are removed for rotation or changing. When
you have the front brake pads replaced, have the
rear brakes inspected, too.
Brake linings should always be replaced as
complete axle sets.

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use spare
tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a comparative rating based
on the wear rate of the tire when tested under
controlled conditions on a specied government
test course. For example, a tire graded 150 would
wear one and a half (1.5) times as well on the
government course as a tire graded 100. The
relative performance of tires depends upon the
actual conditions of their use, however, and may
depart signicantly from the norm due to variations
in driving habits, service practices, and differences
in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured under
controlled conditions on specied government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.
Warning:The traction grade assigned to this tire
is based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
