Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission
shifter in PARK unless the brakes are applied. To shift the
transmission out of PARK, the ignition switch must be
turned to the ON/RUN position (engine running, for
vehicles with 8-speed transmission) and the brake pedal
must be pressed.
In 8-speed vehicles, the brake pedal must also be pressed
to shift from NEUTRAL into DRIVE or REVERSE when
the vehicle is stopped or moving at low speeds.
Six–Speed Automatic Transmission
(5.7L Engine) — If Equipped
The shift lever position display (located in the instrument
cluster) indicates the transmission gear range. The shift
lever is mounted on the right side of the steering column.
You must press the brake pedal to move the shift lever
out of PARK (refer to “Brake/Transmission Shift Inter-
lock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
Pull the shift lever toward you when shifting into RE-
VERSE or PARK, or when shifting out of PARK.
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).
