Your Driving and the Road
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.
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.
4 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.
Here are some tips on night driving.
Drive defensively.
Don't drink and drive.
Adjust your inside rearview mirror to
reduce the glare from headlights
behind you.
Since you can't see as well,
you may
need to slow down and keep more space between
you and other vehicles.

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.
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. If you drive regularly in steep
country, or
if you’re planning to visit
there, here are some tips that can make
your trips safer and more enjoyable.
(See “Off-Road Driving” in the Index
for information about driving off-road.)
Keep your vehicle in good shape.
Check all fluid levels and also the
brakes, tires, cooling system and
transmission. These parts can work
hard
on mountain roads.

Maintenance When Trailer Towing
Your vehicle will need service more often
when you're pulling
a trailer. See the
Maintenance Schedule for more
on this.
rhings that are especially important in
:railer operation are automatic
.ransmission lluid (don't overfill), engine
oil? axle lubricant, belts, cooling system,
and brake adjustment. Each of these
is
covered in this manual, and the Index will
help you find them quickly. If you're
trailering, it's a good idea to review these
sections before you start
your trip.
Check periodically
to see that all hitch

Problems on the Road
If the coolant inside the coolant recovery
tank
is boiling, don’t do anything else
until it cools down.
The coolant level should be at or above
“FULL.” If it isn’t, you may have a leak
in the radiator hoses, heater hoses,
radiator, water pump or somewhere else
in the cooling system. I NOTICE:
I
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
[f there seems to be no leak, check to see
if the electric engine fan is running.
If the
mgine is overheating, the fan should be
running. If it isn’t, your vehicle needs
service.
How to Add Coolant to the Coolant
Recovery
Tank
[f you haven’t found a problem yet, but
:he coolant level isn’t at or above the
“FULL” mark, add a 50/50 mixture of
:lean water (preferably distilled) and a
xoper antifreeze at
the coolant recovery

for more information about the proper
:oolant mix.)

A CAUTION:
Steam and scalding liquids from a
hot cooling system can blow out and
burn you badly. They
are under pres-
sure, and
if you turn the radiator
pressure cap
- even a little - they can
come out
at high speed. Never turn
the cap when the
cooling system,

hot. Wait for the cooling system and
radiator pressure
cap to cool if you
ever have to turn the pressure cap.
