2016 JEEP GRAND CHEROKEE Engine

During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depend-
ing on engine and transmission temperature as well as
vehicle speed. Normal operation will resume once the
transmission temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of transmission
shifting (also known as AutoStick mode; refer to
“AutoStick” in this section for further information). Tog-
gling the gear selector forward (-) or rearward (+) while
in the MANUAL (AutoStick) position will manually
select the transmission gear, and will display the current
gear in the instrument cluster.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that couldresult 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).

STARTING AND OPERATING 475

1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not,shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns OFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal
operation.
NOTE:
Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your earliest
possible convenience. Your authorized dealer has diagnos-
tic equipment to determine if the problem could recur.
If the transmission cannot be reset, authorized dealer
service is required.
AutoStick
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
To activate AutoStick mode, move the gear selector into
the MANUAL (M) position (beside the DRIVE position),
or tap one of the shift paddles on the steering wheel.
Tapping the (-) shift paddle to enter AutoStick mode will
downshift the transmission to the next lower gear, while
tapping (+) to enter AutoStick mode will retain the
current gear. The current transmission gear will be dis-
played in the instrument cluster. In AutoStick mode, you
476 STARTING AND OPERATING

can use the gear selector (in the MANUAL position), or
the shift paddles, to manually shift the transmission.
Tapping the gear selector forward (-) while in the
MANUAL (M) position, or tapping the (-) shift paddle on
the steering wheel, will downshift the transmission to the
next lower gear. Tapping the lever rearward (+) (or
tapping the (+) shift paddle) will command an upshift.
NOTE:The shift paddles may be disabled (or re-enabled,
as desired) using the Uconnect Personal Settings.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver
(using the gear selector, or the shift paddles), 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 can be 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 downshift the
transmission to the lowest gear possible at the current
speed.
5
STARTING AND OPERATING 477

•Transmission shifting will be more noticeable when
AutoStick 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, AutoStick is not active.
To disengage AutoStick, return the gear selector to the
DRIVE position, or press and hold the (+) shift paddle (if
the gear selector is already in DRIVE) until Dis once
again indicated in the instrument cluster. You can shift in
or out of AutoStick at any time without taking your foot
off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their

grip and the vehicle could skid, causing a collision or
personal injury.
SPORT MODE — IF EQUIPPED
Your vehicle is equipped with a Sport Mode feature. This
mode is a configuration set up for typical enthusiast
driving. The engine, transmission, and steering systems
are all set to their SPORT settings. Sport Mode will
provide improved throttle response and modified shift-
ing for an enhanced driving experience, as well the
greatest amount of steering feel. This mode may be
activated and deactivated by pushing the Sport button on
the instrument panel switch bank.
478 STARTING AND OPERATING

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 or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
(Continued)
WARNING!(Continued)
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to roll,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
4WD AUTO
This range is used on surfaces such as ice, snow, gravel,
sand, and dry hard pavement.
NOTE:Refer to “Selec-Terrain – If Equipped” in “Start-
ing And Operating” for further information on the vari-
ous positions and their intended usages.
480 STARTING AND OPERATING

NEUTRAL
This range disengages the driveline from the powertrain.
It is to be used for flat towing behind another vehicle.
Refer to “Recreational Towing” in “Starting And Operat-
ing” for further information.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the power transfer unit
in the NEUTRAL (N) position without first fully
engaging the parking brake. The NEUTRAL (N)
position disengages both the front and rear drive-
shafts from the powertrain and will allow the vehicle
to roll, even if the automatic transmission is in PARK
(or manual transmission is in gear). The parking
brake should always be applied when the driver is
not in the vehicle.
4WD LOW
This range is for low speed four-wheel drive. It provides
an additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:Refer to “Selec-Terrain – If Equipped” for further
information on the various positions and their intended
usages.
Shifting Procedures
4WDHITo4WDLOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),

complete.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
Driver Information Display (DID). Refer to “Driver In-
formation Display (DID)” in “Understanding Your In-
strument Panel” for further information.

482 STARTING AND OPERATING

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 push 4 Low” message will flash from the Driver
Information Display (DID). Refer to “Driver Informa-
tion Display (DID)” in “Understanding Your Instru-
ment 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.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 (N) position without first fully engaging
the parking brake. The NEUTRAL (N) position dis-
engages both the front and rear drive shafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. 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 NEUTRAL.
