STARTING AND OPERATING 63
Brake/Transmission Shift Interlock (BTSI)
System
This vehicle is equipped with a BTSI that holds
the transmission gear selector in PARK unless
the brakes are applied. To shift the
transmission out of PARK, the ignition must be
in the MAR (ON/RUN) mode (engine running or
not) 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.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is
displayed both beside the gear selector and in
the instrument cluster display. To select a gear
range, push the lock button on the gear selector
and move the lever rearward or forward. You
must also press the brake pedal to shift the
transmission out of PARK (or NEUTRAL, when
the vehicle is stopped or moving at low speeds).
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 REVERSE while
driving forward), 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 or
kilometers.
The nine-speed transmission has been
developed to meet the needs of current and
future FWD/AWD vehicles. Software and
calibration is refined to optimize the customer’s
driving experience and fuel economy. By design,
some vehicle and driveline combinations utilize
9th gear only in very specific driving situations
and conditions.
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on
the brake pedal when shifting between these
gears.
The transmission gear selector provides PARK,
REVERSE, NEUTRAL, DRIVE, and Electronic
Range Select (ERS) shift positions. Manual
downshifts can be made using the ERS shift
control. Moving the gear selector into the ERS
(-/+) position (beside the DRIVE position)
activates ERS mode, displays the current gear
in the instrument cluster, and prevents
automatic upshifts beyond this gear. In ERS
mode, toggling the gear selector forward (-) or
rearward (+) will change the highest available
gear Ú page 67.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position (when
pushed forward) it is probably in the ERS (+/-)
position (beside the DRIVE position). In ERS
mode, the transmission gear limit (1, 2, 3, etc.)
is displayed in the instrument cluster. Move the
