Driving on Hills
Driving safely on hills requires
good judgment and an
understanding of what the
vehicle can and cannot do.
{Warning
Many hills are simply too
steep for any vehicle. Driving
up hills can cause the vehicle
to stall. Driving down hills
can cause loss of control.
Driving across hills can
cause a rollover. You could
be injured or killed. Do not
drive on steep hills.
Before driving on a hill, assess
the steepness, traction, and
obstructions. If the terrain ahead cannot be seen, get out
of the vehicle and walk the hill
before driving further.
When driving on hills:
.Use a low gear and keep a
firm grip on the steering
wheel.
.Maintain a slow speed.
.When possible, drive straight
up or down the hill.
.Slow down when
approaching the top of
the hill.
{Warning
Driving to the top of a hill at
high speed can cause a
crash. 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.
.Use headlamps even during
the day to make the vehicle
more visible.
.Never go downhill forward
or backward with the
transmission in N (Neutral).
The brakes could overheat
and you could lose control.
.When driving down a hill,
keep the vehicle headed
straight down. Use a low
gear because the engine will
work with the brakes to slow
the vehicle and help keep
the vehicle under control.
{Warning
Heavy braking when going
down a hill can cause your
brakes to overheat and fade.
This could cause loss of
control and you or others
could be injured or killed.
Apply the brakes lightly
when descending a hill and
use a low gear to keep
vehicle speed under control.
.Avoid turns that take the
vehicle across the incline of
the hill. Driving across an
incline puts more weight on
