256 STARTING AND OPERATING
Vehicles With Mechanical Key:
This vehicle is equipped with a Key Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF (key removal) position. The
key can only be removed from the ignition when the ignition
is in the OFF position, and the transmission is locked in
PARK whenever the ignition is in the OFF position. If the
vehicle's battery becomes discharged, the key will be
trapped in the ignition even when the gear selector is in
PARK. Recharge the battery to allow key removal.
NOTE:
If a malfunction occurs, the system will trap the key fob in
the ignition to warn you that this safety feature is inoperable.
The engine can be started and stopped but the key fob cannot
be removed until you obtain service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. For vehicles
with 8-speed transmission, 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. For vehicles with
6-speed transmission, to shift the transmission out of PARK,
the ignition must be in the ON/RUN mode (engine running
or not) and the brake pedal must be pressed.
Six–Speed Automatic Transmission — If Equipped
Chassis Cab models may use the AS66RC transmission
(which is equipped with a Power Take-Off (PTO) access
cover on the side of the transmission case).
The transmission gear position display (located in the instru-
ment cluster) indicates the transmission gear range. The gear
selector is mounted on the right side of the steering column.
You must press the brake pedal to move the gear selector out
of PARK (refer to “Brake/Transmission Shift Interlock
System” in this section). To drive, move the gear selector
from PARK or NEUTRAL to the DRIVE position. Pull the
gear selector toward you when shifting into REVERSE or
PARK, or when shifting out of PARK.
The electronically-controlled transmission provides a precise
shift schedule. The transmission electronics are self-cali-
brating; therefore, the first few shifts on a new vehicle may
be somewhat abrupt. This is a normal condition, and preci-
sion shifts will develop within a few hundred miles (kilome-
ters).
