Q: What should I do if my vehicle stalls, or is about to stall, and I
can’t make it up the hill?
A: If this happens, there are some things you should do, and there are
some things you must not do. First, here’s what you should do:
0 Push the brake pedal to stop the vehicle and keep it from rolling
0 If your engine is still running, shift the transmission into reverse,
backwards.
Also, apply the parking brake.
release the parking brake, and
slowly back down the hill in reverse.
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, release the parking brake, and slowly back down
the hill as
straight
as possible in reverse.
0 As you are backing down the hill, put your left hand on the steering
wheel at
the 12 o’clock position. This way, you’ll be able to tell if your
wheels are straight and maneuver as you back down. It’s best that you
back down the
hill with your wheels straight rather than in the left or
right direction. Turning
the wheel too far to the left or right will
increase the possibility of a rollover.
Here are
some things you must not do if you stall, or are about to stall,
when going up
a hill.
0 Never attempt to prevent a stall by shifting into NEUTRAL (N) (or
depressing the clutch, if you have a manual transmission) to “rev-up”
the engine and regain forward momentum. This won’t work. Your
vehicle
will roll backwards very quickly and you could go out of
control.

Instead, apply the regular brake to stop the vehicle. Then apply the parking
brake. Shift into reverse, release the parking brake, and slowly back straight
down.
Never attempt to turn around if you are about to stall when going up a
hill. If the hill is steep enough
to stall your vehicle, it’s steep enough to
cause
you to roll over if you turn around. If you can’t make it up the
hill, you must back straight down the hill.
Q: Suppose, after stalling, I try to back down the hill and decide I just
can’t
do it. What should I do?
A: Set the parking brake, put your transmission in PARK (P) (or the
manual transmission
in first gear) , and turn off the engine. Leave the
vehicle and go get some help. Exit on the uphill side and stay clear
of
the path the vehicle would take if it rolled downhill. Do not shift the
transfer case to NEUTRAL
(N) when you leave the vehicle. Leave it in
some gear.
Driving Downhill
When off-roading takes you downhill, you’ll want to consider a number of
things:
How steep is the downhill? Will I be able to maintain vehicle control?
What’s the surface like? Smooth? Rough? Slippery? Hard-packed dirt?
Gravel?
Are there hidden surface obstacles? Ruts? Logs? Boulders?
What’s at the bottom of the hill? Is there a hidden creek bank or even a
river bottom with large rocks?
If
you decide you can go down a hill safely, then try to keep your vehicle
headed straight down, and use a low gear. This way, engine drag can help

your brakes and they won’t have to do all the work. Descend slowly,
keeping your vehicle under control at all times.
0: Are there some things I should not do when driving down a hill?
A: Yes! These are important because if you ignore them you could lose
control and have a serious accident.
0 When driving downhill, avoid turns that take you across the incline of
the hill. A hill that’s not
too steep to drive down may be too steep to
drive across. You could roll over if you don’t drive straight down.
0 Never go downhill with the transmission in NEUTRAL (N), or with the
clutch pedal depressed in a manual shift
. This is called
“free-wheeling.” Your brakes will have to do all the work and could
overheat and fade.
Q: Am I likely to stall when going downhill?
A: It’s much more likely to happen going uphill. But if it happens going
downhill, here’s what to do.
0 Stop your vehicle by applying the regular brakes. Apply the parking
0 Shift to PARK (P) (or to Neutral with the manual transmission) and,
brake.
while still braking, restart the engine.
1, Shift back to a low gear, release the parking brake, and drive straight
down.
If the engine won’t start, get out and get help.
Driving Across an Incline
Sooner or later, an off-road trail will probably go across the incline of a hill.
If this happens, you have to decide whether to try to drive across the incline.
Here are some things to consider:
A hill that can be driven straight up or down may be too steep to drive
across. When you go straight up or down a hill, the length of the wheel
base (the distance from the front wheels to the rear wheels) reduces the
likelihood the vehicle will tumble end over end. But when you drive

Driving ln 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.
If
you have a diesel engine, see “Driving Through Water (Diesel Engines)”
in the Index for more information on driving through water.

After Off-Road Driving
Remove any biush 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.
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.

less traction. It's always wise to go slower and be cautious if rain starts to
fall while you are driving. The surface may get wet suddenly when your
reflexes are tuned for driving
on dry pavement.
The heavier the rain, the harder it is to see. Even if your windshield wiper
blades are in good shape, a heavy rain can make it harder to see road signs
and traffic signals, pavement markings, the edge of the road, and even
people walking.
It's wise to keep your wiping equipment in good shape and keep your
windshield washer tank filled. Replace your windshield wiper inserts when
they show signs of streaking or missing areas on the windshield, or when
strips of rubber start to separate from the inserts.
Driving too fast through large water puddles or even going through some
car washes can cause problems, too. The water may affect your brakes. Try
to avoid puddles. But if you can't, try to slow down before you hit them.
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.

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.
Keep your eyes moving. Scan the road ahead and to the sides. Check
your mirrors and your instruments frequently.
and take a nap, get some exercise, or both. For safety, treat drowsiness
If you get sleepy, pull off the road into a rest, service, or parking area
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.
Know
how to go down hills. The most important thing to know is this:
let your engine
do some of the slowing down. Shift to a lower gear
when
you go down a steep or long hill.

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” 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.
Your anti-lock brakes improve your ability to make a hard stop
on a
slippery road. Even though you have an anti-lock braking system, you’ll
want to begin stopping sooner than
you would on dry pavement. See
“Anti-Lock” in the Index.
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.

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
headlights. 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.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle
is stationary or anchored.
I NOTICE:
Using a power winch with the transmission in gear may damage
the transmission. When operating a power winch, always leave
the transmission in NEUTRAL
(N).
Use the regular brakes, set the parking brake, or block the wheels to keep
your vehicle from rolling.

Power Take-Off (PTO)
NOTICE:
If you have a PTO that will exceed 35 horsepower installed on
your vehicle, it could damage the transfer case or transmission.
When having a PTO installed on your vehicle, make sure that it
will not exceed
35 horsepower.
Before using a power take-off, refer to the manufacturer’s or installer’s
instructions.
NOTICE:
Using a PTO while operating in one place before the vehicle has
reached normal operating temperature can damage the transfer
case or transmission.
If you will be using the PTO while
operating in one place, drive and warm up the vehicle before
using the PTO.
To engage a power take-off
1. Set the parking brake.
2. Shift the transmission into NEUTRAL (N).
3. Hold the clutch pedal down and engage the power take-off.
NOTICE:
Using a PTO for more than four hours without driving your
vehicle can damage the transfer case or transmission.
If using a
PTO for more than four hours without driving your vehicle,
drive your vehicle for
a while to allow the transfer case and
transmission to cool.
If you are going to drive the vehicle, shift the transmission into the gear
you want. Then shift the transfer case into the range you want
(if you
have four-wheel drive), apply the regular brakes and release the
parking brake.
4. Release the clutch (and the regular brakes) as you normally would.
When
you release the clutch, the power take-off will start.
