Your Driving and the Road
Defensive Driving
The best advice anyone can give about
driving is: Drive defensively.
Please start with a very important safety
device
in your Geo: Buckle up. (See
“Safety Belts”
in the Index.)
Defensive driving really means “be ready
for anything.” On city streets, rural roads,
or freeways,
it means “always expect the
unexpected.”
Assume that pedestrians or other drivers
are going to be careless and make
mistakes. Anticipate what they might do.
Be ready for their mistakes.
Rear-end
collisions are about the most
preventable of accidents. Yet they are
common. Allow enough following
distance.
It’s the best defensive driving
maneuver,
in both city and rural driving.
You never know when the vehicle
in front
of you is going to brake or turn suddenly.
Drunken Driving
Death and injury associated with drinking
and driving is a national tragedy. It‘s the
number one contributor
to the highway
death
toll, claiming thousands of victims
every year. Alcohol takes away three
things that anyone needs to drive a
vehicle:
0 Judgment
0 Muscular Coordination
Vision
Police records show that almost half of
all motor vehicle-related deaths involve
alcohol
- a driver, a passenger or
someone else, such as a pedestrian, had
been drinking.
In most cases, these
deaths are the result of someone who
was drinking and driving. About
20,000
motor vehicle-related deaths occur’each
year because of alcohol, and thousands
of people are injured.
Just how much alcohol is too much ifa
person plans to drive‘? Ideally, no one
should drink alcohol and then drive.
But
if one does, then what’s “too much”‘? It
:an be a lot less than many might think.
Although
it depends on each person and
situation, here is some general
information on
the problem. The
Blood Alcohol Content (BAC j of
someone who is drinking depends upon
four things:
How much alcohol is
in the drink.
The drinker’s body weight.
The amount of food that is consumed
before and during drinking.
The length of time
it has taken the
drinker to consume the alcohol.

the curve, while your front wheels are
straight ahead.
Try to adjust your speed
so you can
“drive” through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until you are out of the curve,
and then accelerate gently into the
straightaway.
Steering in Emergencies
There are times when steering can be
more effective than braking. For example,
you come over a hill and find 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 can’t; there isn’t
room. That’s the time for evasive action
- steering around the problem.
Your Geo can perform very well in
emergencies like these. First apply your
brakes, but not enough
to lock your front
wheels. 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. 4n
emergency like this requires close
ittention 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.
Iff-Road Recovery
7ou may find sometime that your right
,heels have dropped off the edge of a
oad onto the shoulder
(A) while you’re
riving.
f the level of the shoulder is only slightl:
lelow the pavement, recovery should be
airly easy. Ease off the accelerator and
hen, if there is nothing in the way, steer
o that your vehicle straddles the edge of
he pavement. You can turn the steering
vheel up to
1/4 turn (B) until the right
ront tire contacts the pavement edge.
?hen turn your steering wheel to go
traight down the roadway.

Service and Appearance Care
When It’s Time for New Tires
One way to tell when it’s time for new
tires
is to check the treadwear indicators,
which will appear
when your tires have
only
2/32 inch (1.6 mm) or less of tread
remaining.
You need a new tire
if
0 You can see the indicators at three or
more places around
the tire.
0 You can see cord or fabric showing
through the tire’s rubber.
The tread or sidewall is cracked, cut
or snagged deep enough to show cord
or fabric.
The tire has a bump, bulge or split.
. . ,186
0 The tire has a puncture, cut, or other
damage that can’t be repaired well
because of the size or location
of the
damage.
Buying New Tires
To find out what kind and size of tires you
need,
look at the Certificationnire label.
The tires installed on your vehicle when it
was new had a Tire Performance Criteria
Specification (TPC Spec) number on each
tire’s sidewall. When you get new tires,
get ones with that same TPC Spec
number. That way, your vehicle
will
continue to have tires that are designed to
give proper endurance, handling, speed
rating, traction, ride and other things
during normal service on your vehicle. If
your tires have an all-season tread design,
the TPC number will be followed by a
“MS” (for mud and snow).
If you ever replace your tires with those
not having a TPC Spec number, make
sure they are the same size, load range,
speed rating and construction type (bias,
bias-belted or radial) as your original
tires.
Uniform Tire Quality Grading
The following information relates to the
system developed by the United States
National Highway Traffic Safety
Administration which grades tires by
treadwear, traction and temperature
performance. (This applies only to
vehicles sold
in the United States.)
Treadwear
The treadwear grade is a comparative
rating based on the wear rate
of the tire
when tested under controlled conditions
on a specified government test course. For
example, a tire graded
150 would wear
one and a half
(1 1/2) times as well on the
government course as a tire graded 100.
