Off-road driving often takes you up, down, or across a hill. Driving safely
on hills requires good judgment and
an understanding of what your vehicle
can and can’t do. There are some hills that simply can’t be driven, no matter\
how well built the vehicle.
Approachiing 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\
.
0 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
Are there obstructions on the hill that can block your path (boulders,
turning maneuvers?
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.
0 Is the hill simply too rough? Steep hills often have ruts, gullies, troughs\
and exposed rocks because they are more susceptible to the eff\
ects of
erosion.

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:
can’t make it up the hill?
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 r\
everse.
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 h\
as
a manual transmission) and restart the engine. Then, shift to \

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 bes\
t 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 As you are backing down the hill, put your left hand on the steering
0 Never attempt to prevent a stall by shifting into “N’ (Neutral) (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 app\
ly the
parking brake. Shift into reverse, release the parking brake, and slowly
back straight down.
0 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.

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?
0 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

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:
(I,
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
likelihood the vehicle will tumble end over end. But when you \
drive
across an incline, the much more nmow track width (the distance
between the left and right wheels) may not prevent the vehicl\
e from
tilting and rolling over.
Also, drivirig across an indline puts more
weight on the downhill wheels. This could cause a downhil slide or a
rollover.
Surface conditions can be
a problem when you drive across a hill.
Loose gravel, muddy spots, or even wet grass can cause your t\
ires to
slip sideways, downhill. If the vehicle slips sideways, it can hit
something that will trip it (a rock,
a rut, etc.) and roll over.
Hidden obstacles can make the steepness of the incline even worse.
I€
you drive across a rock with the uphill wheels, or if the do\
wnhill
wheels drop into a rut
or depression, your vehicle can tilt even more.
For reasons like these,
you need to decide carefully whether to try to drive
across an incline. Just because the trail goes across the incl\
ine doesn’t mean
you have to drive it. The last vehicle to
try it might have rolled over.
Q: What if I’m driving across an incline that’s not too ste\

If your vehicle stalls when you’re crossing an incline, be sure you (and your
passengers) get out on the uphill side, even
if the door there is harder to
open.
If you get out on the downhill side and the vehicle starts to roll over,
you’ll be right in its path.
If you have to walk down the slope, stay out of the path the vehicle will take
if it does roll over.
Driving In Mud, Sand, Snow, Or Ice
When you drive in mud, snow or sand, your wheels won’t get good traction.
You can’t accelerate as quickly, 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.
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.

Page 160 of 340

Downloaded from www.Manualslib.com manuals search engine Hard packed snow and ice offer the worst tire traction. On th\
ese surfaces,
it’s very easy to lase control. On wet ice, for example, the traction is
so poor
that you will have difficulty accelerating. And
if you do get moving, poor
steering and difficult braking can cause you to slide out of control.
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 haw 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. S\
talling 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. Whe\
n you go through water, remember
that when vour brakes get wet, it mav take you longer to
stop.
