9-14 Driving and Operating
Exit on the uphill side and stay clear
of the path the vehicle would take if
it rolled downhill. If the vehicle has
a transfer case with a N (Neutral)
position, do not shift the transfer
case to Neutral when you leave the
vehicle. Leave it in some gear.
{
WARNING
If the vehicle has the two‐speed
automatic transfer case, shifting
the transfer case to Neutral can
cause your vehicle to roll even if
the transmission is in P (Park).
This is because the Neutral
position on the transfer case
overrides the transmission. You
or someone else could be injured.
If you are going to leave your
vehicle, set the parking brake
and shift the transmission to
P (Park). But, if the vehicle has
a two‐speed automatic transfer
case, do not shift the transfer
case to Neutral.
Driving Downhill
When off-roading takes you
downhill, consider:
.
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?
If you decide you can go down a
hill safely, try to keep the vehicle
headed straight down. Use a low
gear so engine drag can help the
brakes so they do not have to do all
the work. Descend slowly, keeping
the vehicle under control at all
times.
{
WARNING
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.
Things not to do when driving down
a hill:
.
When driving downhill, avoid
turns that take you across the
incline of the hill. A hill that is not
too steep to drive down might be
too steep to drive across. The
vehicle could roll over.
.
Never go downhill with the
transmission in N (Neutral),
called free-wheeling. The brakes
will have to do all the work and
could overheat and fade.
