•
Sound the horn as you approach the top of the hill
to let opposing traffic know you're there.
•
Use your headlamps even during the day. They
make you more visible to oncoming traffic.

CAUTION:
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.
Q:
What should I do if my vehicle stalls, or is
about to stall, and I can't make it up the hill?
A:
If this happens, there are some things you should
do, and there are some things you must not do.
First, here's what you should do:
•
Push the brake pedal to stop the vehicle and keep it
from rolling backwards. Also, apply the parking
brake.
•
If your engine is still running, shift the transmission to
REVERSE (R), release the parking brake, and slowly
back down the hill in REVERSE (R).
•
If your engine has stopped running, you'll need to
restart it. With the brake pedal pressed and the
parking brake still applied, shift the transmission to
PARK (P) and restart the engine. Then, shift to
REVERSE (R), release the parking brake, and slowly
back down the hill as straight as possible in
REVERSE (R).
•
As you are backing down the hill, put your left hand
on the steering wheel at the 12 o'clock position. This
way, you'll be able to tell if your wheels are straight
and maneuver as you back down. It's best that you
back down the hill with your 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 won't 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.
