Chevrolet 2007 Silverado 1500 Pickup Owner's Manual page 377

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) (or shift to
NEUTRAL if your vehicle has a manual
transmission) 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) (or pressing the clutch, if you
have a manual transmission) 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.
