Brake/Transmission Shift Interlock System; Five-Speed Automatic Transmission - Jeep Grand Cherokee 2012 Owner's Manual

ignition when the ignition is in the LOCK/OFF position,
and once removed the shift lever is locked in PARK.

Brake/Transmission Shift Interlock System

This vehicle is equipped with a Brake Transmission Shift
Interlock (BTSI) system that holds the shift lever in the
PARK position unless the brakes are applied. To move
the shift lever out of the PARK position, the ignition
switch must be turned to the ON/RUN position (engine
running or not) and the brake pedal must be pressed.

Five-Speed Automatic Transmission

The shift lever position display (located in the instrument
panel cluster) indicates the transmission gear range. You
must press the brake pedal to move the shift lever out of
the PARK position (refer to "Brake/Transmission Shift
Interlock System" in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
The shift lever (with AutoStick shift paddles mounted
on the steering wheel) provides PARK, REVERSE, NEU-
TRAL, and DRIVE shift positions.
SPORT mode is only available in the "Selec-Track" posi-
tions of TRACK and SPORT.
