light PONTIAC G5 2007 Repair Manual

Remember: ABS does not change the time you
need to get your foot up to the brake pedal or
always decrease stopping distance. If you get too
close to the vehicle in front of you, you will not have
time to apply your brakes if that vehicle suddenly
slows or stops. Always leave enough room up
ahead to stop, even though you have ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You may feel a slight brake pedal pulsation
or notice some noise, but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a
situation that requires hard braking.
If you have ABS, you can steer and brake at the
same time. However, if you do not have ABS, your
rst reaction — to hit the brake pedal hard and
hold it down — may be the wrong thing to do.
Your wheels can stop rolling. Once they do, the
vehicle cannot respond to your steering.Momentum will carry it in whatever direction it was
headed when the wheels stopped rolling. That
could be off the road, into the very thing you were
trying to avoid, or into traffic.
If you do not have ABS, use a “squeeze” braking
technique. This will give you maximum braking
while maintaining steering control. You can do this
by pushing on the brake pedal with steadily
increasing pressure.
In an emergency, you will probably want to
squeeze the brakes hard without locking the
wheels. If you hear or feel the wheels sliding, ease
off the brake pedal. This will help you retain
steering control. If you do have ABS, it is different.
SeeAnti-Lock Brake System (ABS) on page 223.
In many emergencies, steering can help you
more than even the very best braking.
225

Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction
System (ETS) that limits wheel spin. This is
especially useful in slippery road conditions.
The system operates only if it senses that one
or both of the front wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power and may
also upshift the transaxle to limit wheel spin.
You may feel or hear the system working, but this
is normal.
A LOW TRACTION message will appear on the
Driver Information Center (DIC) when the traction
control system is actively limiting wheel spin.
Slippery road conditions may exist if this message
is displayed, so adjust your driving accordingly.
If your vehicle is in cruise control when the
Enhanced Traction System begins to limit wheel
spin, the cruise control will automatically
disengage. When road conditions allow you to
safely use it again, you may re-engage the cruise
control. SeeCruise Control on page 143.When the system is on,
this warning light will
come on to let you know
there’s a problem.
If the warning light stays on, or comes on when
you’re driving, there may be a problem with
your Enhanced Traction System and your vehicle
may need service. When this warning light is
on, the system will not limit wheel spin. Adjust your
driving accordingly.
The Enhanced Traction System warning light may
come on for the following reasons:
If you turn the system off by moving the
shift lever to LOW (L), the warning light
will come on and stay on. To turn the system
back on, move the shift lever back to a
position other than LOW (L). The warning light
should go off.
226

The warning light will come on when you set
your parking brake with the engine running,
and it will stay on if your parking brake
does not release fully. If the transaxle shift
lever is in any position other than LOW (L) and
the warning light stays on after your parking
brake is fully released, it means there is
a problem with the system.
If the traction control system is affected by an
engine related problem, the system will turn
off and the warning light will come on.
If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the transaxle shift lever is in any
position other than LOW (L), your vehicle needs
service.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 268for more information.
Steering
Electric Power Steering
If the engine stalls while you are driving, the
power steering assist system will continue
to operate until you are able to stop your vehicle.
If you lose power steering assist because the
electric power steering system is not functioning,
you can steer, but it will take more effort.
If you turn the steering wheel in either direction
several times until it stops, or hold the steering
wheel in the stopped position for an extended
amount of time, you may notice a reduced amount
of power steering assist. The normal amount of
power steering assist should return shortly after a
few normal steering movements.
The electric power steering system does not
require regular maintenance. If you suspect
steering system problems and/or the POWER
STEERING message comes on, contact
your dealer for service repairs. SeeDIC Warnings
and Messages on page 177.
227

Off-Road Recovery
You may nd that your right wheels have dropped
off the edge of a road onto the shoulder while
you are driving.
If the level of the shoulder is only slightly below
the pavement, recovery should be fairly easy.
Ease off the accelerator and then, if there
is nothing in the way, steer so that your vehicle
straddles the edge of the pavement.You can turn the steering wheel up to one-quarter
turn until the right front tire contacts the pavement
edge. Then turn your steering wheel to go
straight down the roadway.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then
goes back into the right lane again. A simple
maneuver?
Not necessarily! Passing another vehicle on a
two-lane highway is a potentially dangerous
move, since the passing vehicle occupies the
same lane as oncoming traffic for several seconds.
A miscalculation, an error in judgment, or a brief
surrender to frustration or anger can suddenly put
the passing driver face to face with the worst of all
traffic accidents — the head-on collision.
230

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as
much light to see the same thing at night as a
20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the
day in bright sunshine you are wise to wear
sunglasses. Your eyes will have less trouble
adjusting to night. But if you are driving, do not
wear sunglasses at night. They may cut down on
glare from headlamps, but they also make a
lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or
even several seconds, for your eyes to re-adjust
to the dark. When you are faced with severe glare,
as from a driver who does not lower the high
beams, or a vehicle with misaimed headlamps,
slow down a little. Avoid staring directly into
the approaching headlamps.
234

Keep the windshield and all the glass on your
vehicle clean — inside and out. Glare at night is
made much worse by dirt on the glass. Even
the inside of the glass can build up a lm caused
by dust. Dirty glass makes lights dazzle and
ash more than clean glass would, making the
pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of
a roadway when you are in a turn or curve.
Keep your eyes moving; that way, it is easier to
pick out dimly lighted objects. Just as the
headlamps should be checked regularly for
proper aim, so should your eyes be
examined regularly. Some drivers suffer from
night blindness — the inability to see in dim
light —and are not even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble.
On a wet road, you cannot stop, accelerate, or turn
as well because your tire-to-road traction is not
as good as on dry roads. And, if your tires do not
have much tread left, you will get even less
traction. It is always wise to go slower and be
cautious if rain starts to fall while you are driving.
The surface may get wet suddenly when your
reexes are tuned for driving on dry pavement.
235

The heavier the rain, the harder it is to see.
Even if your windshield wiper blades are in good
shape, a heavy rain can make it harder to see
road signs and traffic signals, pavement markings,
the edge of the road, and even people walking.
It is wise to keep your windshield wiping equipment
in good shape and keep your windshield washer
uid reservoir lled with washer uid. Replace your
windshield wiper inserts when they show signs
of streaking or missing areas on the windshield, or
when strips of rubber start to separate from the
inserts.
{CAUTION:
Wet brakes can cause accidents. They may
not work as well in a quick stop and may
cause pulling to one side. You could lose
control of the vehicle.
After driving through a large puddle of
water or a car wash, apply your brake pedal
lightly until your brakes work normally.Driving too fast through large water puddles or
even going through some car washes can cause
problems, too. The water may affect your brakes.
Try to avoid puddles. But if you cannot, try to slow
down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much water can
build up under your tires that they can actually ride
on the water. This can happen if the road is wet
enough and you are going fast enough. When your
vehicle is hydroplaning, it has little or no contact
with the road.
Hydroplaning does not happen often. But it can if
your tires do not have much tread or if the
pressure in one or more is low. It can happen if a
lot of water is standing on the road. If you can
see reections from trees, telephone poles,
or other vehicles, and raindrops dimple the water’s
surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds.
There just is not a hard and fast rule about
hydroplaning. The best advice is to slow down
when it is raining.
236

Driving Through Deep Standing Water
Notice:If you drive too quickly through
deep puddles or standing water, water can
come in through your engine’s air intake and
badly damage your engine. Never drive through
water that is slightly lower than the underbody
of your vehicle. If you cannot avoid deep
puddles or standing water, drive through them
very slowly.
Driving Through Flowing Water
{CAUTION:
Flowing or rushing water creates strong
forces. If you try to drive through owing
water, as you might at a low water
crossing, your vehicle can be carried away.
CAUTION: (Continued)
CAUTION: (Continued)
As little as six inches of owing water can
carry away a smaller vehicle. If this
happens, you and other vehicle occupants
could drown. Do not ignore police
warning signs, and otherwise be very
cautious about trying to drive through
owing water.
Some Other Rainy Weather Tips
Besides slowing down, allow some extra
following distance. And be especially careful
when you pass another vehicle. Allow yourself
more clear room ahead, and be prepared to
have your view restricted by road spray.
Have good tires with proper tread depth. See
Tires on page 320.
237

City Driving
One of the biggest problems with city streets is
the amount of traffic on them. You will want
to watch out for what the other drivers are doing
and pay attention to traffic signals.Here are ways to increase your safety in city
driving:
Know the best way to get to where you are
going. Get a city map and plan your trip
into an unknown part of the city just as you
would for a cross-country trip.
Try to use the freeways that rim and crisscross
most large cities. You will save time and
energy. SeeFreeway Driving on page 239.
Treat a green light as a warning signal. A
traffic light is there because the corner is
busy enough to need it. When a light turns
green, and just before you start to move,
check both ways for vehicles that have not
cleared the intersection or may be running the
red light.
238

Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such as
after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out.Of course, you will nd experienced and able
service experts in GM dealerships all across
North America. They will be ready and willing to
help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?
