Ignition Park Interlock; Brake/Transmission Shift Interlock System; Eight-Speed Automatic Transmission - RAM 1500 2019 User Manual

WARNING! (Continued)
Do not leave the key fob in or near the

vehicle (or in a location accessible to
children), and do not leave the ignition
in the ACC or ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
CAUTION!
Shift into or out of PARK or REVERSE

only after the vehicle has come to a
complete stop.
Do not shift between PARK, REVERSE,

NEUTRAL, or DRIVE when the engine is
above idle speed.
Before shifting into any gear, make sure

your foot is firmly pressing the brake
pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.

Ignition Park Interlock

This vehicle is equipped with an Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the OFF mode. This helps the
driver avoid inadvertently leaving the vehicle
without placing the transmission in PARK.
This system also locks the transmission in
PARK whenever the ignition is in the OFF
mode.
NOTE:
The transmission is NOT locked in PARK
when the ignition is in the ACC mode (even
though the engine will be off). Ensure that
the transmission is in PARK, and the ignition
is OFF (not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock System (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must
be running and the brake pedal must be
pressed.
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.

Eight-Speed Automatic Transmission

The transmission is controlled using a rotary
electronic gear selector located on the
instrument panel. The transmission gear
range (PRND) is displayed both above the
gear selector and in the instrument cluster.
To select a gear range, simply rotate the gear
selector. You must press the brake pedal to
shift the transmission out of PARK (or
NEUTRAL, when the vehicle is stopped or
moving at low speeds). To shift past multiple
gear ranges at once (such as PARK to
DRIVE), simply rotate the gear selector to the
appropriate detent. Select the DRIVE range
for normal driving.
NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects PARK while
driving), the position indicator will blink
continuously until the selector is returned to
the proper position, or the requested shift
can be completed.
The electronically-controlled transmission
adapts its shift schedule based on driver
inputs, along with environmental and road
conditions. The transmission electronics are
self-calibrating; therefore, the first few shifts
on a new vehicle may be somewhat abrupt.
