•
As you are backing down the hill, put your left
hand on the steering wheel at the 12 o'clock
position. This way, you will be able to tell if the
wheels are straight and maneuver as you
back down. It is best that you back down the
hill with the 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.
•
Never attempt to prevent a stall by shifting
into NEUTRAL (N) to rev-up the engine
and regain forward momentum. This will
not 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 to REVERSE (R), 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 is steep
enough to cause you to roll over if you turn
around. If you cannot 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 cannot do it. What
should I do?
A:
Set the parking brake, put the transmission in
PARK (P) 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.
Driving Downhill
When off-roading takes you downhill, you will want
to consider a number of things:
•
How steep is the downhill? Will I be able to
maintain vehicle control?
•
What is the surface like? Smooth? Rough?
Slippery? Hard-packed dirt? Gravel?
•
Are there hidden surface obstacles? Ruts?
Logs? Boulders?
•
What is at the bottom of the hill? Is there a
hidden creek bank or even a river bottom
with large rocks?
