Driving Uphill
Once you decide it is safe to drive
up the hill:
Use a low gear and get a firm
grip on the steering wheel.
Get a smooth start up the hill
and try to maintain speed. Not
using more power than needed
can avoid spinning the wheels or
sliding.
{
WARNING
Turning or driving across steep
hills can be dangerous. You could
lose traction, slide sideways, and
possibly roll over. You could be
seriously injured or killed. When
driving up hills, always try to go
straight up.
Try to drive straight up the hill if
at all possible. If the path twists
and turns, you might want to find
another route.
Ease up on the speed as you
approach the top of the hill.
Attach a flag to the vehicle to be
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 are there.
Use headlamps even during the
day to make the vehicle more
visible to oncoming traffic.

WARNING
Driving to the top (crest) of a
hill at full speed can cause an
accident. There could be a
drop-off, embankment, cliff,
or even another vehicle. You
could be seriously injured or
killed. As you near the top of a
hill, slow down and stay alert.

Driving and Operating
If the vehicle stalls, or is about to
stall, and you cannot make it up
the hill:
Push the brake pedal to stop the
vehicle and keep it from rolling
backwards and apply the
parking brake.
If the engine is still running, shift
the transmission to R (Reverse),
release the parking brake, and
slowly back down the hill in
R (Reverse).
If the engine has stopped
running, you need to restart it.
With the brake pedal pressed
and the parking brake still
applied, shift the automatic
transmission to P (Park) or the
manual transmission to Neutral
and restart the engine. Then,
shift to R (Reverse), release the
parking brake, and slowly back
down the hill as straight as
possible in R (Reverse).
