2014 JEEP GRAND CHEROKEE stop start

Eight–Speed Automatic Transmission
Your vehicle is equipped with a state of the art, fuel
efficient eight-speed transmission. The electronic shift
lever in this vehicle does not slide like a conventional
shifter. Instead, the shift lever is spring loaded and moves
forward and rearward, always returning to the center
position after each gear is selected. The transmission gear
(PRND) is displayed both on the shift lever and in the
Electronic Vehicle Information Center (EVIC). To select a
gear range, press the lock button on the shift lever and
move the lever rearward or forward. You must 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 sec-
tion). To shift past multiple gear ranges at once (such as
PARK to DRIVE), move the lever past the first (or second)
detent. 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).
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 press 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
404 STARTING AND OPERATING

CAUTION!(Continued)
•Before moving the shift lever out of PARK, you
must start the engine, and also press the brake
pedal. Otherwise, damage to the shift lever 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
shift lever and push the lever all the way forward until
it stops. When released, the lever will return to the
center position.
• With brake pedal released, look at the transmission
gear position display and verify that it indicates the
PARK position. 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. The engine may be
started in this range. 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.
408 STARTING AND OPERATING

switch between DRIVE and SPORT modes, tap the shift
lever rearward. SPORT mode is only accessible from
DRIVE.
NOTE:When Sport Mode is enabled, the vehicle’s air
suspension system will operate in “Aero” Mode. Please
refer to “Quadra Lift” within this section for further
information.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission
may not re-engage if the engine is turned off and
restarted. The Malfunction Indicator Light (MIL) may be illuminated. A message in the instrument cluster will
inform the driver of the more serious conditions, and
indicate what actions may be necessary.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage after en-
gine shutdown, perform this procedure only in a desired
location (preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Turn the ignition switch to the OFF position. On vehicles with Keyless Enter-N-Go™, press and hold
the ignition switch until the engine turns OFF.
410 STARTING AND OPERATING

In Paddle Shift mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition would
result. It will remain in the selected gear until another
upshift or downshift is chosen, except as described
below.
•The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• You can start out, from a stop, in first or second gear
(or third gear, in 4LO range, Snow mode, or Sand
mode). Tapping (+) at a stop will allow starting in
second gear. Starting out in second gear is helpful in
snowy or icy conditions. •
If a requested downshift would cause the engine to
over-speed, that shift will not occur.
• The system will ignore attempts to upshift at too low
of a vehicle speed.
• Holding the (-) paddle depressed will progressively
downshift the transmission to the lowest gear possible
at the current speed.
• Transmission shifting will be more noticeable when
Paddle Shift mode is enabled.
• The system may revert to automatic shift mode if a
fault or overheat condition is detected.
NOTE: When Selec-Speed or Hill Descent Control is
enabled, Paddle Shift mode is not active. Pressing the
(+/-) shift paddles in Selec-Speed or Hill Descent Control
simply limits the highest allowed gear. Shifts below and
up to that gear will occur automatically.
412 STARTING AND OPERATING

This transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging
the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive
shafts from the powertrain and will allow the vehicle
to move regardless of the transmission position. The
parking brake should always be applied when the
driver is not in the vehicle.
414 STARTING AND OPERATING

NOTE:If shift conditions/interlocks are not met, or a
transfer case motor temperature protection condition
exists, a “For 4x4 Low Slow Below 3 mph (5 km/h) Put
Trans in “N” Press 4 Low” message will flash from the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,
shift the transmission into NEUTRAL, and press the
“4WD LOW” button once on the transfer case switch. The
“4WD LOW” indicator light in the instrument cluster
will flash and go out when the shift is complete. NOTE:
•
If shift conditions/interlocks are not met, or a transfer
case motor temperature protection condition exists, a
“For 4x4 High Slow Below 3 mph (5 km/h) Put Trans
in N Press 4 Low” message will flash from the Elec-
tronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further
information.
• Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being prop-
erly aligned. Several attempts may be required for
clutch teeth alignment and shift completion to occur.
The preferred method is with the vehicle rolling 0 to
3 mph (0 to 5 km/h). If the vehicle is moving faster
than 3 mph (5 km/h), the transfer case will not allow
the shift.5

Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into “N”. 4. If vehicle is equipped with Quadra-Lift™ air suspen-
sion, ensure the vehicle is set to Normal Ride Height.
5. Using a ballpoint pen or similar object, press and hold the recessed transfer case “N” button (located by the
selector switch) for four seconds. The light behind the
“N” symbol will blink, indicating shift in progress.
The light will stop blinking (stay on solid) when the
shift to “N” is complete. A “FOUR WHEEL DRIVE
SYSTEM IN NEUTRAL” message will display on the
EVIC (Electronic Vehicle Information Center). Refer to
“Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further
information.
