Steering in Emergencies
There are times when steering can
be more effective than braking.
For example, you come over a hill
and nd a truck stopped in your
lane, or a car suddenly pulls
out from nowhere, or a child darts
out from between parked cars
and stops right in front of you.
You can avoid these problems by
braking — if you can stop in time.
But sometimes you cannot; there is
not room. That is the time for
evasive action — steering around
the problem.
Your vehicle can perform very well
in emergencies like these. First
apply the brakes. SeeBraking on
page 8-14. It is better to remove as
much speed as you can from a
possible collision. Then steer around
the problem, to the left or right
depending on the space available.An emergency like this requires close
attention and a quick decision. If you
are holding the steering wheel at the
recommended 9 and 3 o’clock
positions, you can turn it a full
180 degrees very quickly without
removing either hand. But you have
to act fast, steer quickly, and just as
quickly straighten the wheel once
you have avoided the object.
The fact that such emergency
situations are always possible is a
good reason to practice defensive
driving at all times and wear safety
belts properly.
Off-Road Recovery
Your vehicle’s right wheels can
drop off the edge of a road onto the
shoulder while 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. Turn the
steering wheel 3 to 5 inches (about
one-eighth turn) until the right front
tire contacts the pavement edge.
Then turn the steering wheel to go
straight down the roadway.

Passing
Passing another vehicle on a
two-lane road can be dangerous.
To reduce the risk of danger
while passing:
Look down the road, to the sides,
and to crossroads for situations
that might affect a successful
pass. If in doubt, wait.
Watch for traffic signs, pavement
markings, and lines that could
indicate a turn or an intersection.
Never cross a solid or
double-solid line on your side of
the lane.
Do not get too close to the
vehicle you want to pass. Doing
so can reduce your visibility.
Wait your turn to pass a slow
vehicle.
When you are being passed,
ease to the right.
Loss of Control
Let us review what driving experts
say about what happens when
the three control systems — brakes,
steering, and acceleration — do
not have enough friction where the
tires meet the road to do what
the driver has asked.
In any emergency, do not give up.
Keep trying to steer and constantly
seek an escape route or area of
less danger.
Skidding
In a skid, a driver can lose control
of the vehicle. Defensive drivers
avoid most skids by taking
reasonable care suited to existing
conditions, and by not overdriving
those conditions. But skids are
always possible.The three types of skids correspond
to your vehicle’s three control
systems. In the braking skid, the
wheels are not rolling. In the steering
or cornering skid, too much speed or
steering in a curve causes tires to
slip and lose cornering force. And in
the acceleration skid, too much
throttle causes the driving wheels
to spin.
If your vehicle starts to slide,
ease your foot off the accelerator
pedal and quickly steer the way
you want the vehicle to go. If you
start steering quickly enough,
your vehicle may straighten out.
Always be ready for a second skid
if it occurs.
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
you want to slow down and
adjust your driving to these
conditions. It is important to slow
down on slippery surfaces because
stopping distance is longer and
vehicle control more limited.
Driving and Operating 8-21
2008 - Pontiac G8 Owner Manual

While driving on a surface with
reduced traction, try your best to
avoid sudden steering, acceleration,
or braking, including reducing
vehicle speed by shifting to a lower
gear. Any sudden changes could
cause the tires to slide. You
might not realize the surface is
slippery until your vehicle is
skidding. Learn to recognize warning
clues — such as enough water,
ice, or packed snow on the road to
make a mirrored surface — and
slow down when you have any
doubt.
Remember: Any Antilock Brake
System (ABS) helps avoid only the
braking skid.Driving at Night
Night driving is more dangerous than
day driving because some drivers
are likely to be impaired — by alcohol
or drugs, with night vision problems,
or by fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by
adjusting the inside rearview
mirror.
Slow down and keep more space
between you and other vehicles
because headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into
approaching headlamps.
Keep the windshield and all glass
on your vehicle clean — inside
and out.
Keep your eyes moving,
especially during turns or curves.
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 might need
at least twice as much light to see
the same thing at night as a
20-year-old.

2008 - Pontiac G8 Owner Manual

Driving in Rain and on
Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or owing water.
{CAUTION
Wet brakes can cause crashes.
They might not work as well in
a quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
(Continued)
CAUTION (Continued)
Flowing or rushing water
creates strong forces. Driving
through owing water could
cause your vehicle to be
carried away. If this happens,
you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to
drive through owing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle’s
tires so they 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.There is no hard and fast rule about
hydroplaning. The best advice is
to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping
equipment in good shape.
Keep the windshield washer uid
reservoir lled.
Have good tires with proper tread
depth. SeeTires on page 9-39.
Turn off cruise control,
if equipped.

Before Leaving on a
Long Trip
To prepare your vehicle for a long
trip, consider having it serviced
by your dealer/retailer before
departing.
Things to check on your own include:
Windshield Washer Fluid:
Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:
All levels checked?
Lamps:Do they all work and are
lenses clean?
Tires:Are treads good? Are tires
inated to recommended
pressure?
Weather and Maps:Safe to
travel? Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, nd a
safe place to park your vehicle
and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on at or rolling terrain. Tips for
driving in these conditions include:
Keep the vehicle serviced
and in good shape.
Check all uid levels and brakes,
tires, cooling system, and
transmission.
Going down steep or long hills,
shift to a lower gear.
{CAUTION
If you do not shift down, the
brakes could get so hot that
they would not work well. You
would then have poor braking
or even none going down a hill.
You could crash. Shift down to
let the engine assist the brakes
on a steep downhill slope.
8-24 Driving and Operating
2008 - Pontiac G8 Owner Manual

{CAUTION
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will
have to do all the work of
slowing down and they could
get so hot that they would not
work well. You would then have
poor braking or even none
going down a hill. You could
crash. Always have the engine
running and the vehicle in gear
when going downhill.
Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
Top of hills: Be alert — something
could be in your lane (stalled car,
accident).
Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape
for winter.
You might want to put winter
emergency supplies in your
vehicle.
Include an ice scraper, a small
brush or broom, a supply of
windshield washer uid, a rag,
some winter outer clothing, a small
shovel, a ashlight, a red cloth,
and reective warning triangles.
And, if you will be driving under
severe conditions, include a small
bag of sand, a piece of old carpet, or
a couple of burlap bags to help
provide traction. Be sure you
properly secure these items in
your vehicle.
Also seeTires on page 9-39.

Driving on Snow or Ice
Most of the time, those places
where the tires meet the road
probably have good traction.
However, if there is snow or ice
between the tires and the road, you
can have a very slippery situation.
You have a lot less traction, or grip,
and need to be very careful.
What is the worst time for this?
Wet ice. Very cold snow or ice can
be slick and hard to drive on. But wet
ice can be even more trouble
because it can offer the least traction
of all. You can get wet ice when it is
about freezing, 32°F (0°C), and
freezing rain begins to fall. Try to
avoid driving on wet ice until salt and
sand crews can get there.
Whatever the condition — smooth
ice, packed, blowing, or loose
snow — drive with caution.
Accelerate gently. Try not to break
the fragile traction. If you accelerate
too fast, the drive wheels will spin
and polish the surface under the tires
even more.The Antilock Brake System (ABS)
improves your vehicle’s stability
when you make a hard stop
on a slippery road. Even though you
have ABS, begin stopping sooner
than you would on dry pavement.
SeeAntilock Brake System (ABS)
on page 8-15.
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 can 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 can
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 the hazard warning
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.
You can run the engine to keep
warm, but be careful.
