Understanding Gearshift Positions - Ford 1999 Mustang Owner's Manual

Driving
Do not drive your vehicle until you verify
that the brakelamps are working.
If your vehicle gets stuck in mud or snow it may be
rocked out by shifting from forward and reverse
gears, stopping between shifts, in a steady pattern.
Press lightly on the accelerator in each gear.
Do not rock the vehicle for more than a few
minutes. The transmission and tires may be
damaged or the engine may overheat.
Always set the parking brake fully and make
sure the gearshift is latched in P (Park).
Turn off the ignition whenever you leave your
vehicle.
If the parking brake is fully released, but the
brake warning lamp remains illuminated, the
brakes may not be working properly. See your
dealer or a qualified service technician.
Driving with a 4–speed automatic transmission

Understanding gearshift positions

Pull the gearshift lever towards you and downward
to move the automatic gearshift.
Hold the brake pedal down while you move
the gearshift lever from P (Park) to another
position. If you do not hold the brake pedal down,
your vehicle may move unexpectedly and injure
someone.
