Six-Speed Automatic Transmission
The shift lever position display (located in the instrument
panel cluster) indicates the transmission gear range. You
must press the brake pedal to move the shift lever out of
the PARK position (Refer to Brake/Transmission Shift
Interlock System in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission provides a
precise shift schedule. 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).
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
