being moved out of PARK without a driver in place
(Fig. 27).
OPERATION
The Brake Transmission Shifter/Ignition Interlock
(BTSI) is engaged whenever the ignition switch is in
the LOCK or ACCESSORY position (Fig. 28). An
additional electrically activated feature will prevent
shifting out of the PARK position unless the brake
pedal is depressed at least one-half inch. A magnetic
holding device integral to the interlock cable is ener-
gized when the ignition is in the ON/RUN position.
When the key is in the ON/RUN position and the
brake pedal is depressed, the shifter is unlocked and
will move into any position. The interlock system
also prevents the ignition switch from being turned
to the LOCK or ACCESSORY position, unless the
shifter is in the gated PARK position.
The following chart describes the normal operation
of the Brake Transmission Shift Interlock (BTSI) sys-
tem. If the “expected response” differs from the vehi-
cle’s response, then system repair and/or adjustment
is necessary.
AUTOSTICK
OPERATION
Autostick is a driver–interactive transaxle feature
that offers manual gear shifting capability. When the
shifter is moved into the Autostick position, the tran-
saxle remains in whatever gear it was using before
Autostick was activated. Moving the shifter to the
left (towards the driver) causes a downshift and mov-
ing to the right (towards the passenger) causes an
upshift. The instrument cluster will illuminate the
selected gear. The vehicle can be launched in 1st,
2nd, or 3rd gear while in the Autostick mode. The
speed control is operable in 3rd and 4th gear Auto-
stick mode. Speed control will be deactivated if the
transaxle is shifted to 2nd gear. Shifting into OD
position cancels the Autostick mode, and the tran-
saxle resumes the OD shift schedule.
AUTOMATIC OVERRIDES
For safety, durability, and driveability, some shifts
are executed automatically or prevented.
