Driving in Mud, Sand, Snow or Ice Hard packed snow and ice offer the worst tire traction.
When you drive in mud, snow or sand, your wheels
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. On
these surfaces, it’s very easy to lose control. On wet
ice, for example, the traction is
so poor that you will
poor steering and difficult braking can cause you to slide
out of control.
won’t
get good traction. you can’t accelerate as quickly,
have difficulty accelerating. And if you do get moving,
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.
Driving on frozen lakes, ponds or rivers can be
dangerous. Underwater springs, currents under
the ice, or sudden thaws can weaken the ice.
Your
vehicle could fall through the ice and you and
your passengers could drown. Drive your vehicle
on safe surfaces only.

Driving in Water
Light rain causes no special off-road driving problems.
But heavy rain can mean flash flooding, and flood
waters demand extreme caution.
Find out how deep the water is before you drive through
it. If it’s deep enough to cover your wheel hubs, axles or
exhaust pipe, don’t try
it -- you probably won’t get
through. Also, water that deep can damage your axle
and other vehicle parts.
If the water isn’t too deep, then drive through it slowly.
At fast speeds, water splashes
on your ignition system
and your vehicle can stall. Stalling can also occur if you
get your tailpipe under water. And, as long as your
tailpipe is under water, you’ll never be able to start your
engine. When you go through water, remember that
when your brakes get wet,
it may take you longer
to stop.
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only shallow water, it can still wash away the
ground from under your tires, and
you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
See “Driving Through Water” in the Index for more
information on driving through water.

After Off-Road Driving
Remove any brush or debris that has collected on the
underbody, chassis or under the hood. These
accumulations can be a fire hazard.
After operation in mud or sand, have the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the body structure,
steering, suspension, wheels, tires and exhaust system
for damage. Also, check the
fuel lines and cooling
system for any leakage.
Your vehicle will require more frequent service due to
off-road use. Refer to
the Maintenance Schedule for
additional information.
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.

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 secund, and you could crash and
be injured
.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead
and
to the sides. Check your mirrors and your
instruments frequently.
0 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.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.

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. 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 OF; 0 O 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.
Unless you have the anti-lock braking system, you’ll
want to brake very gently, too.
(If you do have anti-lock,
see “Anti-Lock” in the Index. This system improves
your vehicle’s stability when you make a hard stop on a
slippery road.) Whether
you have the anti-lock braking
system or not, you’ll want to begin stopping sooner than
you would on dry pavement. Without anti-lock brakes,
if you feel your vehicle begin
to slide, let up on the
brakes a little. Push the brake pedal down steadily to get
the most traction you can.

Remember, unless you have anti-lock, if you brake so
hard that your wheels stop rolling, you’ll just slide.
Brake
so your wheels always keep rolling and you can
still steer.
Whatever your braking system, allow greater
following distance on any slippery road.
Watch for slippery spots. The road might be fine
until you hit
a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear
in
shaded areas where the sun can’t reach: around
clumps
of trees, behind buildings or under bridges.
Sometimes the surface
of a curve or an overpass may
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’re actually on
the ice, and avoid sudden steering maneuvers.
If You’re 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:

ProCarManuals.com

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 headlamps. 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 long as you can.
To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.
Re - -1tional Vehicle Towing

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found
on the driver’s door lock pillar tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle. It also gives
you
important information about the number of people that
can be in your vehicle and the total weight that you can
carry. This weight is called the Vehicle Capacity Weight
and includes the weight of all occupants, cargo and all
nonfactory-installed options.

The other label is the Certification label, also found on
the driver’s door lock pillar. It tells
you the gross weight
capacity
of your vehicle, called the GVWR (Gross
Vehicle Weight Rating). The GVWR includes the weight
of the vehicle, all occupants, fuel and cargo. Never
exceed the GVWR for your vehicle, or the
Gross Axle
Weight Rating (GAWR) for either the front or rear axle.
And,
if you do have a heavy load, you should spread it
out. Don’t carry more than
400 lbs. (181 kg) in your rear
area when four people are in your two-wheel-drive
vehicle. If you have a four-wheel-drive vehicle, don’t
carry more than
200 Ibs. (91 kg) in your rear area when
four people are in your vehicle.
