Ignition Park Interlock; Brake/Transmission Shift Interlock (Btsi) System; 8-Speed Automatic Transmission - Jeep GRAND CHEROKEE L 2023 Owner's Manual

WARNING!
Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing chil-
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the transmis-
sion gear selector.
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 ON/RUN position.
A child could operate power windows, other
controls, or move the vehicle.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
Shift into or out of PARK or REVERSE (R) only

after the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,

NEUTRAL, or DRIVE (D) when the engine is
above idle speed.
Before shifting into any gear, make sure your

foot is firmly pressing the brake pedal.

GNITION ARK NTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be in
PARK (P) before the ignition can be turned to the
OFF position. 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 position.
NOTE:
The transmission will NOT shift out of the PARK
position if the engine is not running even when the
brakes are applied. Ensure that the transmission is
in PARK, and the ignition is OFF (not in the ON/RUN
position) before exiting the vehicle.

NTERLOCK YSTEM
This vehicle is equipped with a BTSI system 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.
STARTING AND OPERATING
8-S A T
PEED UTOMATIC RANSMISSION
The transmission is controlled using a rotary
electronic gear selector located on the center
console. 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. This is a normal condition,
and precision shifts will develop within a few
hundred miles (kilometers).
