Chrysler 2004 PT Cruiser - Manual (Page 184)

Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of Park and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON positions. Always depress the brake
pedal first,
before moving the gear selector out of PARK.
Automatic Transaxle Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK and the shift knob push button
is out. It also prevents shifting out of PARK unless the
key is in the OFF or ON positions.
NOTE: If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Four Speed Automatic Transaxle
The electronically controlled transaxle provides a precise
shift schedule. The transaxle electronics are self calibrat-
ing; 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 shift cycles.
Reset Mode
The transaxle is monitored electronically for abnormal
conditions. If a condition is detected that could cause
damage, the transaxle shifts automatically into second
gear. The transaxle remains in second gear despite the
forward gear selected. Park (P), Reverse (R), and Neutral
(N) will continue to operate. This second gear limp-in
feature allows the vehicle to be driven to a dealer for
service without damaging the transaxle.
In the event that the problem has been momentary, the
transaxle can be reset to regain all forward gears.
Stop the vehicle and shift into Park (P).
