thick, wet haze that may even coat your
windshield. You can often spot these fog
patches or mist layers with your
headlights. But sometimes they can be
waiting for you as you come over a hill
or dip into a shallow valley. Start your
windshield wipers and washer, to help
clear accumulated road dirt. Slow down
carefully.
Tips on Driving in Fog
If you get caught in fog, turn your
headlights on low beam, even in
daytime. You’ll see
- and be seen -
better. Don’t use your high beams.
The light
will bounce off the water droplets that
make up fog and reflect back at you.
Use your defogger. In high humidity,
even a light buildup of moisture on the
inside
of the glass will cut down on your
already limited visibility. Run your
windshield wipers and washer
occasionally. Moisture can build up on
the outside glass, and what seems to be
fog may actually be moisture on the
outside
of your windshield.
Treat dense
fog as an emergency. Try to
find a place to pull off the road.
Of
course you want to respect another’s property,
but you might need to put
something between you and moving
vehicles
- space, trees, telephone poles,
a private driveway, anything that
removes you from other traffic.
If visibility
is near zero and you must
stop but are unsure whether you are
away from the road, turn your lights on,
start your hazard warning flashers, and
sound your horn at intervals or when
you hear approaching traffic.
Pass other vehicles
in fog only if you
can see far enough ahead to pass safely.
Even then, be prepared to delay your
pass
if you suspect the fog is worse up
ahead. If other vehicles try to pass you,
make
it easy for them.

H City Dnving

One of the biggest problems with city
streets is
the amount of traffic on them.
You’ll 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. Try not to drive
around trying to pick out
a familiar
street
or landmark. 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’ll
save time and energy. (See the next
section, “Freeway Driving.”)
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.
Obey all posted speed limits.
But
remember that they are for ideal road,
weather and visibility conditions. You
may need to drive below the posted
limit in bad weather or when visibility
is especially poor.

hear emergency vehicles.

Freeway Driving
Mile for mile, freeways (also called
thruways, parkways, expressways,
turnpikes, or superhighways) are the
safest
of all roads. But they have their
own special rules.
The most important advice on freeway
driving is: Keep up with traffic and keep
to the right. Drive at the same speed
most of the other drivers are driving.
Too-fast or too-slow driving breaks a
smooth traffic flow. Treat the left lane
on a freeway as a passing lane.
Entering the Freeway
At the entrance there is usually a ramp
that leads to the freeway. If you have a
clear view of the freeway as you drive
along the entrance ramp, you should
begin to check traffic. Try to determine
where you expect to blend with
the
flow. If traffic is light, you may have no
problem. But if
it is heavy, find a gap as
you move along the entering lane and
time your approach. Try to merge into
the gap at close to the prevailing speed.
Switch on your turn signal, check your
rearview mirrors as you move along,
and glance over your shoulder as often
as necessary. Try to blend smoothly
with the traffic flow.
Driving on the Freeway
Once you are on the freeway, adjust
your speed to the posted limit or to the
prevailing rate if it's slower. Stay
in the
right lane unless you want to pass. If
you are on a two-lane freeway, treat the
right lane as the slow lane and the left
lane as the passing lane.
If you are on a three-lane freeway, treat
the right lane as
the slower-speed
through lane, the middle lane as the
higher-speed through lane, and the left
lane as the passing lane.
Before changing lanes, check your
rearview mirrors. Then use your
turn
signal. Just before you leave the lane,
glance quickly over your shoulder to

make sure there isn’t another vehicle in
your
‘ ‘blind’ ’ spot.
If you are moving from an outside to a
center lane on a freeway having more
than two lanes, make sure another
vehicle isn’t about to move into the
same spot. Look at the vehicles two
lanes over and watch for telltale signs:
turn signals flashing, an increase
in
speed, or moving toward the edge of the
lane. Be prepared to delay your move.
Once you are moving on the freeway,
make certain you allow a reasonable
following distance. Expect to move
slightly slower at night.
... 166
Leaving the Freeway
When you want to leave the freeway,
move to the proper lane well in
advance. Dashing across lanes at the last
minute is dangerous. If you miss your
exit do not, under any circumstances,
stop and back up. Drive on to the next
exit.
At each exit point is a deceleration lane.
Ideally it should be long enough for you
to enter
it at freeway speed (after
signaling, of course) and
then do your
braking before moving onto
the exit
ramp. Unfortunately, not all deceleration
lanes are long enough
- some are too
short for all the braking. Decide when
to start braking. If
you must brake on the through
lane, and if there is traffic
close behind you, you can allow a little
extra time and flash your brake lights (in
addition
to your turn signal) as extra
warning that you are about
to slow
down and 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. For example,
40 mph (65 km/h)
might seem like only
20 mph (30 km/h).
Obviously, this could lead to serious
trouble
on a ramp designed for
20 mph (30 km/h)!

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?

Weather Forecasts: What’s 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?
On the Road
Unless you are the only driver, it is
good to share the driving task with
others. Limit turns behind the wheel to
about
100 miles (160 km) or two hours
at a sitting. Then, either change drivers
or stop for some refreshment like
coffee, tea or
soft drinks and some
limbering up. But do stop and move
around. Eat lightly along the way. Heavier meals tend
to make some people
sleepy.
On two-lane highways or undivided
multilane highways that do not have
controlled access, you’ll want to watch
for
some situations not usually found on
freeways. Examples are: stop signs and
signals, shopping centers with direct
access to the highway, no passing zones
and school zones, vehicles turning left
and right
off the road, pedestrians,
cyclists, parked vehicles, and even
animals.
Highway Hypnosis
Is there actually such a condition as
“highway hypnosis”?
Or is it just plain
falling asleep at the wheel? Call it
highway hypnosis, lack
of awareness, or
whatever.
There is something about an easy stretch
of road with the same scenery, along
with the hum
of the tires on the road,
the drone of the engine, and the rush
of
the wind against the vehicle that can
make you sleepy. Don’t let
it happen to
you!
If it does, your vehicle can leave
the road in
less than a second, and you
could crash and be injured.
ProCarManuals.com

What can you do about highway
hypnosis? First, be aware that it can
happen.
Then here are some tips:
Make sure your vehicle is well
ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the
road ahead and to the sides. Check
your rearview mirrors frequently and
your instruments from time
to time.
This can help you avoid a fixed stare.
Wear good sunglasses in bright light.
Glare can cause drowsiness. But don’t
wear sunglasses at night. They will drastically reduce your overall
vision
at the very time you need all the
seeing power you have.
If you get sleepy, pull off the road
into a rest, service or parking area
and take a nap, get some exercise, or
both. For safety, treat drowsiness on
the highway as an emergency.
As in any driving situation, keep pace
with traffic and allow adequate
following distances.

You may want to put winter
emergency supplies in your vehicle.
Include an ice scraper, a small brush
or broom, a supply of windshield
washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight,
a red cloth, and a couple of reflective
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.

Driving on Snow or Ice
Most of the time, those places where
your tires meet the road probably have
good traction.
However,
if there is snow or ice
between your tires and the road, you can
have a very slippery situation. You’ll
have a lot less traction or “grip” and
will need to be very careful.
t
What’s 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 may offer
the least traction
of all. You can get
“wet ice” when it’s about freezing
(32°F; OOC) 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.

If you have no blankets or extra

Snow can trap exhaust gases
under your vehicle. This can
cause deadly
CO (carbon
monoxide) gas to get inside.
CO
could overcome you and kill you.
You can't see it or smell it,
so you
might not know it was in your
vehicle. Clear away snow from around the base
of your vehicle,
especially any that is blocking your
exhaust pipe. And check around
again from time to time to be sure
snow doesn't collect there.
Open a window just a little on
the
side of the vehicle that's away
from the wind. This will help keep
co out. Run your engine only as long as you
must. This saves fuel. When
you run the
engine, make it go a little faster than
just idle. That is, push the accelerator
slightly. This uses less fuel for the heat
that you get and it keeps the battery
charged. You will
need a well-charged
battery to restart the vehicle, and
possibly for signaling later on with your
headlights.
Let the heater run for
awhile.
Then, shut the engine off and close the
window almost all the way to preserve
the heat.
Start the engine again and
repeat this only when you feel really
uncomfortable from the cold. But do it
as little as possible. Preserve the fuel as

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.
