Jeep grand cherokee 2015 Owner's Manual page 433

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).
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 shift lever provides PARK, REVERSE,
NEUTRAL, DRIVE and SPORT shift positions. Once in
the DRIVE range, tapping the shift lever rearward will
toggle between SPORT mode and DRIVE mode. You do
not need to push the shift lever button when toggling
between DRIVE and SPORT modes. Manual shifts can be
made using the shift paddles mounted on the steering
wheel. Pressing the shift paddles (-/+) while in the
DRIVE or SPORT position will manually select the trans-
mission gear, and will display the current gear in the
instrument cluster. Refer to Paddle Shift Mode in this
section for further information.
