Ease up on your speed as you approach the top of
the hill.
Attach a flag
to the vehicle to make you more visible
to approaching traffic on trails or hills.
Sound the horn as you approach the top of
the hill to
let opposing traffic know you’re there.
Use your headlamps even during the day. They make
you more visible
to oncoming traffic.

Driving to the top (crest) of a hill at full speed can
cause an accident. There could be a drop-off,
embankment,
cliff, or even another vehicle. You
could be seriously injured or killed.
As you near
the top
of a hill, slow down and stay alert.

First, here’s what you
should do:
Push the brake pedal to stop the vehicle and keep it
from rolling backwards. Also, apply
the parking brake.

to REVERSE
(R), release the parking brake, and
slowly back down the
hill in REVERSE (R).
If your engine has stopped running, you’ll need to
restart it.
With the brake pedal depressed and the
parking brake still applied, shift the transmission
to
PARK (P) (or, shift to NEUTRAL (N) if your
vehicle has a manual transmission) and restart
the
engine. Then, shift to REVERSE (R), release the
parking brake,
and slowly back down the hill as
straight as possible in REVERSE
(R).

Driving at Night
....... .^ .... ......................... ." ....................... I .........................
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 headlamps behind you.
Since
you can't see as well, you may need to slow
down and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads.
Your
headlamps can light up only so much road ahead.
In remote areas, watch for animals.
If you're tired, pull off the road in
a safe place
and rest.

Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50-year-old
driver may require at least twice as much light to see the
same thing at night as
a 20-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you’re
driving, don’t wear sunglasses at night. They may cut
down on glare from headlamps, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching
headlamps.
It can take a second or two, or even several
seconds, for your eyes
to readjust to the dark. When
you
are faced with severe glare (as from a driver who
doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down
a little. Avoid
staring directly into the approaching headlamps. Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass.
Even the inside of the glass
can build up a film caused by dust. Dirty glass makes lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you
are in a turn or curve. Keep your
eyes moving; that way, it’s easier
to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and
aren’t even aware
of it.

A CAJTldN:
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 is 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 (or batteries) charged. You will need a
well-charged battery (or batteries) to restart
the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater run for awhile.
If you have
a diesel engine, you may have to run it at a
higher speed to get enough heat. 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.

I a CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control.
You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts
for replacement.
I NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance
to the body and chassis.
Whenever a wheel, wheel bolt or wheel
nut is replaced
on a dual wheel setup, check the wheel
nut torque after
100, 1,000 and 6,000 miles ( 160, 1 600 and 10 000 km)
of driving. For proper torque, see “Wheel Nut Torque’’
in the Index. See
“Changing a
Flat Tire” in the Index for
more information.
Used Replacement Wheels

Putting a used wheel on your vehicle is dangerous.
You can’t know how it’s been used or how far it’s
been driven. It could fail suddenly and
cause an

I NOTICE:
If your vehicle has dual wheels or P26975R16 size
tires, don’t use tire chains. They can damage
your
vehicle because there’s not enough clearance.

Electrical System
Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see “Servicing
Your Air Bag-Equipped Vehicle” in the Index.
Headlamps
The headlamp wiring is protected by an internal circuit
breaker.
An electrical overload will cause the lamps to go
on and off, or in some cases to remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem and
not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
