Automatic Transmission
There are several different positions for your shift lever.
If your vehicle is equipped with an automatic transmission, it now features
an electronic shift position indicator
within the instrument cluster. This
display must be powered anytime the shift lever is capable
of being moved
out of the
PARK (P) position. This means that if your key is in the OFF
position, but not locked, there will be a small current drain on your battery
which could discharge your battery over
a period of time. If you have a need
to leave your key
in the ignition in the OFF position for an extended period
for any reason,
it is recommended that you disconnect the battery cable
from the battery to prevent discharging your battery.
PARK (P) -This locks your rear wheels. It’s the best position to use
when you start your engine because your vehicle can’t move easily.

could damage your transmission. Shift to REVERSE
(R) only
after your vehicle is stopped.
To rock your vehicle back and forth to get out of snow, ice or sand
without damaging your transmission, see
“If You‘re Stuck: In Sand,
Mud, Ice or Snow”
in the Index.
a NEUTRAL (N) - In this position, your engine doesn’t connect with
the wheels. To restart when you’re already moving, use NEUTRAL (N)
only. Also, use NEUTRAL (N) when your vehicle is being towed.
