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 the engine is still running, shift the
transmission to REVERSE (R), release
the parking brake, and slowly back down
the hill in REVERSE (R).
•
If the 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 the
wheels are straight and maneuver as you
back down. It is best that you back down the
hill with the 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.
