vehicle and begin to drive away, you
may hear a momentary motor or
clicking noise. The ABS motor comes
on momentarily when the vehicle
reaches
8 mph (12 km/h). This is the
ABS system testing itself.
Here’s how anti-lock works. Let’s say

pedal as soon as you feel the vehicle
start to slide. Quickly steer the way you
want the vehicle to go. If you start
steering quickly enough, your vehicle
will straighten out. As
it does, straighten
the front wheels.
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is
on the road. For safety,
you’ll want to slow down and adjust
your driving to these conditions. It is
important to slow down
on slippery
surfaces because stopping distance
will
be longer and vehicle control more
limited. While
driving on a surface with reduced
traction,
try your best to avoid sudden
steering, acceleration, or braking
(including engine braking by shifting to
a lower gear). Any sudden changes
could cause the tires to slide.
You may
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: the
rear wheel anti-lock
braking system (RWAL) helps avoid
only a rear braking skid. In a braking
skid (where the front wheels are no
longer rolling), release enough pressure
on the brakes to get the front wheels
rolling again. This restores steering
control. Push the brake pedal down
steadily when you have to stop
suddenly. As long as the front wheels
are rolling, you will have steering
control. Steer the way you want to go.

Getting out on the downhill
(low) side of a vehicle
stopped across 811 incline is
dangerous. If the vehicle rolls
over, you could be crushed or
killed. Always get out on the
uphill (high) side of the vehicle
and
stay well clear of the rollover
path.

Driving in Mud, Sand, Snow, or Ice
When you drive in mud, snow, or sand,
your wheels won’t get good traction.
You can’t accelerate as quickly, turning
is more difficult, and you’ll need longer
braking distances.
It’s best to use
a low gear when you’re
in mud - the deeper the mud, the lower
the gear. In really deep mud, the idea is
to keep your vehicle moving
so you
don’t get stuck.
When you drive on sand, you’ll sense a
change in wheel traction. But it will
depend upon how loosely packed the
sand is. On loosely packed sand (as
on
beaches or sand dunes) your tires will tend
to sink into the sand. This has an
effect on steering, accelerating, and
braking. You may want to reduce the air
pressure in your tires slightly when
driving on sand. This will improve
traction,
Hard packed snow and ice offer the
worst tire traction. On these surfaces,
it’s very easy to lose control. On wet
ice, for example, the traction is
so poor
that you will have difficulty
accelerating. And if you do get moving,
poor steering and difficult braking can
cause you to slide out of control.

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’re going fast enough. When
your vehicle is hydroplaning, it has little
or no contact with
the road.
You might not be aware of
hydroplaning.
You could drive along for
some time without realizing your tires
aren’t in constant contact with the road.
You could find out the hard way: when
you have to slow, turn, move out to
pass
- or if you get hit by a gust of
wind. You could suddenly find yourself
out of control. Hydroplaning
doesn’t happen often. But
it can if your tires haven’t 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 reflections
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 isn’t a hard and fast
rule about hydroplaning. The best advice
is to slow down when it is raining, and
be careful.
Some Other Rainy Weather Tips
Turn on your headlights - not just
your parking lights - to help make
you more visible to others.
Look for hard-to-see vehicles coming
from behind.
You may want to use
your headlights even in daytime
if it’s
raining hard.
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.

I Driving a Long
Distunce
Although most long trips today are made
on freeways, there are still many made
on regular highways.
Long-distance driving on freeways and
regular highways is the same in some
ways. The trip has
to be planned and the
vehicle prepared, you drive at
higher-than-city speeds, and there are
longer turns behind the wheel. You’ll
l enjoy your trip more if you and your
vehicle are in good shape. Here are
some tips for a successful long trip.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well
rested. If you must start when you’re
not fresh
- such as after a day’s work
- don’t plan to make too many miles
that first 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’s
ready to go.
If it needs service, have it
done before starting out. Of course,
you’ll find experienced and able service
experts in Geo dealerships all across
North America. They’ll 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?
Lights: 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 inflated
to
the recommended pressure?

Torque Lock (Automatic
Transmission)
If you are parking on a hill and you
don’t shift your transmission into
P
(Park) properly, the weight of the
vehicle may put too much force on the
parking pawl in the transmission.
You
may find it difficult to pull the shift
lever out of
P (Park). This is called “torque
lock.”
To prevent torque lock,
always be sure to shift into
P (Park)
properly before you leave the driver’s
seat.
To find out how, see ‘‘Shifting into
P (Park)” in the Index.
When you are ready to drive, move the
shift lever out
of P (Park) BEFORE you
release the parking brake.
If torque lock does occur, you may need
to have another vehicle push yours a
little uphill
to take some of the pressure
from the transmission,
so you can pull
the shift lever out
of P (Park).
Winter Driving
Here are some tips for winter driving:
Have your Geo in good shape for
winter. Be sure your engine coolant
mix is correct.
Snow tires can help in loose snow,
but they may give you less traction on
ice than regular tires.
If you do not
expect
to be driving in deep snow, but
may have to travel over ice, you may
not want
to switch to snow tires at all.

Your Driving and the Road
Will the trailer brake parts take
3,000 psi (20 650 kPa) of pressure? If
not, the trailer brake system must not
be used with your vehicle.
If everything checks out this far, then
make the brake fluid tap at the port
on the master cylinder that sends fluid
to the rear brakes. But don’t use
copper tubing
for this. If you do, it
will bend and finally break off. Use
steel brake tubing.

Driving With a Trailer
Towing a trailer requires a certain
amount
of experience. Before setting out
for the open road, you’ll 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
so responsive as your vehicle
is by itself. Before you
start, check
the trailer hitch
and platform, safety chains, electrical
connector, lights, 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 lights and any trailer brakes are still
working.

It’s unusual for a tire to “blow out’’
while you’re driving, especially
if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But if you should ever
have a “blowout,
” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop well
out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a skid and may require
the same correction you’d use
in a skid. In any
rear blowout, remove your
foot
from the accelerator pedal. Get the
vehicle under control by steering
the
way you want the vehicle to go. It may
be
very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road
if possible.
If your tire goes flat, the next section
shows how to use your jacking
equipment to change a flat tire safely.
ChanginQ a Flat lire
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a
level place. Turn
on your hazard
warning flashers.
