Traveling to Remote Areas
It makes sense to plan your trip,
especially when going to a remote area.
Know the terrain and plan your route. You
are much less likely to get bad surprises.
Get accurate maps of trails and terrain.
Try to learn of any blocked or closed
roads.
It’s also a good idea to travel with at least
one other vehicle.
If something happens
to one of them, the other can help quickly.
Does your vehicle have a winch? If
so, be
sure to read the winch instructions. In a
remote area, a winch can be handy if you
get stuck. But you’ll want to know how to
use it properly.
Getting Familiar with Off-Road
Driving
It’s a good idea to practice in an area
that’s safe and close to home before you
go into the wilderness. Off-road driving
does require some new and different
driving skills. Here’s what we mean.
Tune your senses to different kinds of
signals. Your eyes, for example, need to
constantly sweep the terrain for
unexpected obstacles. Your ears need to
listen for unusual tire or engine sounds. With
your arms, hands, feet, and body
you’ll need to respond to vibrations and
vehicle bounce.
Controlling your vehicle is the key to
successful off-road driving. One
of the
best ways to control your vehicle is to
control your speed. Here are some things
to keep in mind. At higher speeds:
0 you approach things faster and you
have less time to scan the terrain for
obstacles.
0 you have less time to react.
0 you have more vehicle bounce when
you drive over obstacles.
0 you’ll need more distance for braking,
especially since you’re on an unpaved
surface.
Scanning the Terrain
Off-road driving can take you over many
different kinds of terrain. You need to be
familiar with the terrain and its many
different features. Here are some things to
consider.
Surface Conditions. Off-roading can
take you over hard-packed dirt, gravel,
rocks, grass, sand, mud, snow or ice.
Each of these surfaces affects the steering,
acceleration, and braking of your vehicle
in different ways. Depending upon the
kind of surface you are on, you may
experience slipping, sliding, wheel
spinning, delayed acceleration, poor
traction, and longer braking distances.
Surface Obstacles. Unseen or hidden
obstacles can be hazardous.
A rock, log,
hole, rut, or bump can startle you if
you’re not prepared for them. Often these
obstacles are hidden by grass, bushes,
snow or even the rise and fall
of the
terrain itself. Here are some things to
consider:
0 Is the path ahead clear?
0 Will the surface texture change
abruptly up ahead?

Your Driving and the Road
0 Does the travel take you uphill or
downhill? (There’s more discussion of
these subjects later.)
change direction quickly?
0 Will you have to stop suddenly or
When you drive over obstacles or rough
terrain, keep a firm grip
on the steering
wheel.
Ruts, troughs, or other surface
features can jerk the wheel out of your
hands
if you’re not prepared.
When you drive over bumps, rocks, or
other obstacles, your wheels can leave
the
ground. If this happens, even with one or
two wheels, you can’t control the vehicle
as well or at all.
Because you will be on an unpaved
surface,
it’s especially important to avoid
sudden acceleration, sudden turns, or
sudden braking.
In a way, off-road driving requires a
different kind of alertness from driving on
paved roads and highways. There are no
road signs, posted speed limits or signal
lights.
You have to use your own good
judgment about what is safe and what
isn’t.
Drinking and driving can be very
dangerous on any road. And this
is
certainly true for off-road driving. At the
. . .I10
very time you need special alertness and
driving skills, your reflexes, perceptions
and judgment can be affected by even a
small amount of alcohol.
You could have
a serious - or even fatal - accident if
you drink and drive or ride with a driver
who has been drinking. (See “Drunken
Driving”
in the Index.)
Driving On Off-Road Hills
Off-road driving often takes you up,
jown, or across a hill. Driving safely on
hills requires good judgment and an
understanding of what your vehicle can
md can’t do. There are some hills that
;imply can’t be driven, no matter how
well built the vehicle.
Approaching a Hill
When you approach a hill, you need to
decide if
it’s one of those hills that’s just
too steep to climb, descend, or cross.
Steepness can be hard
to judge. On a very
small
hill, for example, there may be a
smooth, constant incline with only a small
change
in elevation where you can easily
see all the way to the top. On a large hill,
the incline may get steeper as you near
the top, but you may not see this because
the crest of
the hill is hidden by bushes,
grass,
or shrubs.
Here are some other things
to consider as
you approach a hill.
Is there a constant incline, or does the
hill get sharply steeper in places?
Is there good traction on the hillside,
or will the surface cause tire slipping?
Is there a straight path up or down the
hill so you won’t have to make turning
maneuvers?
Are there obstructions on the hill that
can block your path (boulders, trees,
logs or ruts)?
What’s beyond the hill?
Is there a cliff,
an embankment, a drop-off, a fence?
Get out and walk the
hill if you don’t
know. It’s the smart way to find out.
ProCarManuals.com

0 Is the hill simply too rough‘? Steep hills
often have ruts, gullies, troughs and
exposed rocks because
they are more
susceptible
to the effects of erosion.
Driving Uphill
Once you decide you can safely drive up
the hill,
you need to take some special
steps.
0 Use a low gear and get a firm grip on
the steering wheel.
Get a smooth start up the hill and try
to maintain your speed. Don’t use
more power than
you need, because
you don’t want your wheels
to start
spinning or sliding.
Try to drive straight up the hill if at a1
possible.
If the path twists and turns,
you might want to find another route.
0
0
0
0
Ease up on your speed as you
approach the top
of the hill.
Attach a flag to the vehicle to tnake
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 headlights even during the
day. They make you more visible
to
oncoming traffic.
Q: What should I do if my vehicle
A:
0
0
0
0
stalls, or is about to stall, and I can’t
make
it up the hill?
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:
Push the brake pedal
to stop the
vehicle and keep
it from rolling
backwards. Also, apply
the parking
brake.
If your engine is still running, shift the
transmission into reverse, 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
“P” (Park) (or, shift to “N” (Neutral)
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.
As you are backing down the hill, put
your left hand
on the steering wheel at
the
12 o’clock position. This way,

0 Are there hidden surface obstacles?
Ruts? Logs? Boulders?
0 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.
Q: 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.
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.
Never go downhill with the
transmission in “N” (Neutral), 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.
Avoid braking
so hard that you lock
the front wheels when going downhill.
If your front wheels are locked, you
can’t steer your vehicle. If your
wheels lock up during downhill
braking, you may feel the vehicle
starting to slide sideways.
To regain
your direction, just ease
off the brakes
and steer to keep the front of the
vehicle pointing straight downhill.
Q: Am I likely to stall when going
downhill?
A:
0
0
0
0
It‘s much more likely to happen going
uphill.
But if it happens going
downhill, here’s what to do.
Stop your vehicle by applying the
regular brakes. Apply the parking
brake.
Shift to
“P” (Park) (or to Neutral with
the manual transmission) and, while
still braking, restart the engine.
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 happeris, you have to decide whether
to try to drive across the incline. Here are
some things to consider:
0 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
