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:
0
Push the brake pedal to stop the vehicle and keep it from rolling
0
If your engine
is
still running, shift the transmission into reverse,
backwards. Also, apply the parking brake.
release the parking brake, and slowly back down the hill in reverse.
If your engine has stopped running, you'll need to restart it. With the
brake pedal depressed and the parking brake still applied, shift the
transmission to PARK (P) (or, shift to NEUTRAL
(N)
if your vehicle
has a manual transmission) and restart the engine. Then, shift to
reverse, release the parking brake, and slowly back down the hill as
straight
as
possible in reverse.
0
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.
0
Never attempt to prevent a stall by shifting into NEUTRAL (N) (or
depressing the clutch, if you have
a
manual transmission) 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.
