Q:
What should I do if my vehicle stalls,
or is about to stall, and I cannot 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 is 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 will
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 will be able to tell if your
wheels are straight and maneuver as you back
down. It is 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 will not
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.
•
Never attempt to turn around if you are about
to stall when going up a hill. If the hill is steep
enough to stall your vehicle, it is steep enough
to cause you to roll over if you turn around.
If you cannot make it up the hill, you must
back straight down the hill.
