2016 JEEP GRAND CHEROKEE brake

•The transmission will launch (from a stop) in second
gear.
• The torque converter clutch may engage at lower
engine speeds and remain on longer.
• The engine idle speed will be lower.
• The overall driving performance will be more conser-
vative.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
NOTE: ECO mode is only available in AUTO mode.
Active Noise Cancellation
Your vehicle is equipped with an Active Noise Cancella-
tion System, this system is designed to address the
change in exhaust noise whenever the vehicle is operat-
ing in Fuel Economy Mode (ECO) or 4 cylinder mode. This system relies on four microphones embedded in the
headliner to detect the exhaust drone and prompt an
onboard frequency generator to create counteracting
sound waves through the audio system’s speakers and
sub-woofer. This helps keep the vehicle quiet at highway
speeds.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
besides the gear selector bezel and in the Driver Infor-
mation Display (DID). To select a gear range, press the
lock button on the gear selector and move the lever
rearward or forward. To shift the transmission out of
PARK, the engine must be running and the brake pedal
must be pressed. You must also press the brake pedal 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 sec-
tion). Select the DRIVE range for normal driving.5
STARTING AND OPERATING 471

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 gear selector provides PARK, RE-
VERSE, NEUTRAL, DRIVE and MANUAL (AutoStick)
shift positions. Manual shifts can be made using the
AutoStick shift control (refer to “AutoStick” in this
section for further information). Toggling the gear selec-
tor forward (-) or rearward (+) while in the MANUAL
(AutoStick) position (beside the DRIVE position), ortapping the shift paddles (+/-), will manually select the
transmission gear, and will display the current gear in the
instrument cluster.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position (when pushed
forward) it is probably in the AutoStick (+/-) position
(beside the DRIVE position). In AutoStick mode, the
transmission gear (1, 2, 3, etc.) is displayed in the
instrument cluster. Move the gear selector to the right
(into the DRIVE [D] position) for access to PARK, RE-
VERSE, and NEUTRAL.
472 STARTING AND OPERATING

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.NOTE:
After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.

WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission
is in PARK before leaving the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit

WARNING! (Continued)
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the Key Fob.
When the ignition is in the OFF mode, the trans-
mission is locked in PARK, securing the vehicle
against unwanted movement.
• When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the Key Fob
from the vehicle, and lock the vehicle.

474 STARTING AND OPERATING

WARNING!(Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the gear selector.
• Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition in the ACC or ON/RUN mode. A
child could operate power windows, other controls,
or move the vehicle.
CAUTION!
• DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
• Before moving the gear selector out of PARK, you
must start the engine, and also press the brake
pedal. Otherwise, damage to the gear selector could
result.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion:
• When shifting into PARK, press the lock button on the
gear selector and push the lever all the way forward
until it stops and is fully seated.
• Look at the transmission gear position display and
verify that it indicates the PARK position (P).

STARTING AND OPERATING 475

•With brake pedal released, verify that the gear selector
will not move out of PARK.
NOTE: If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position (when pushed
forward) it is probably in the AutoStick (+/-) position
(beside the DRIVE position). In AutoStick mode, the
transmission gear (1, 2, 3, etc.) is displayed in the
instrument cluster. Move the gear selector to the right
(into the DRIVE [D] position) for access to PARK, RE-
VERSE, and NEUTRAL.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake and shift the transmission into PARK if you must
leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
