Driving Downhill
When off-roading takes you downhill, you
11
want to
consider
a
number of things:
How steep is the downhill? Will I be able
to
maintain
What's the surface like? Smooth? Rough? Slippery?
Are there hidden surface obstacles? Ruts? Logs?
What's at the bottom of the hill? Is there a hidden
vehicle control?
Hard-packed dirt? Gravel?
Boulders?
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.

Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could
cause loss of control and
a serious accident.
Apply the brakes lightly when descending a
hill and use a low gear to keep vehicle speed
under control.
&:
Are there some things I should not do when
A:
Yes! These are important because if you ignore them
driving down a hill?
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
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.
