Eight-Speed Automatic Transmission - Jeep Grand Cherokee 2016 Owner's Manual

486 STARTING AND OPERATING
• The overall driving performance will be more conser-
vative.
• Vehicles with Quadra-Lift air suspension will operate
in Aero mode over a broader speed range. Refer to
Quadra-Lift in Starting And Operating for further
information.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Active Noise Cancellation — Summit And SRT
Models Only
Your vehicle is equipped with an Active Noise Cancella-
tion System. This system uses four microphones embed-
ded in the headliner to detect undesirable exhaust noise,
which sometimes occurs when operating in ECO mode.
An onboard frequency generator creates counteracting
sound waves through the audio system to help keep the
vehicle quiet.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
on the gear selector bezel and in the Driver Information
Display (DID). To select a gear range, press 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 to shift from NEUTRAL
into DRIVE or REVERSE when the vehicle is stopped or
moving at low speeds (refer to "Brake/Transmission
Shift Interlock System" in this section). Select the DRIVE
range for normal driving.
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).
