2016 JEEP GRAND CHEROKEE automatic transmission

•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

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),
the ignition switch in the ON position or the engine
running, shift the transmission into “N”, and push
the “4WD LOW” button once on the transfer case switch.

STARTING AND OPERATING 481

Selec-Terrain consists of the following positions:
•Snow –
Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. When in Snow mode (depending on
certain operating conditions), the transmission may use
second gear (rather than first gear) during launches, to
minimize wheel slippage. If equipped with air suspen-
sion, the default ride height for Snow is NRH.
• Auto – Fully automatic full time four-wheel drive
operation can be used on and off road. Balances
traction with seamless steering feel to provide im-
proved handling and acceleration over two-wheel
drive vehicles. If equipped with air suspension, the
level will change to NRH.
• Sand – Off road calibration for use on low traction
surfaces such as sand or wet grass. Driveline is maxi-
mized for traction. Some binding may be felt on less
forgiving surfaces. The electronic brake controls are set to limit traction control management of throttle and
wheel spin. If equipped with air suspension, the
default ride height for Sand is NRH.
• Mud – Off road calibration for use on low traction
surfaces such as mud. Driveline is maximized for
traction. Some binding may be felt on less forgiving
surfaces. The electronic brake controls are set to limit
traction control management of throttle and wheel
spin. If equipped with air suspension, the level will
change to Off Road 1.
• Rock – Off road calibration only available in 4WD Low
range. The vehicle is raised (if equipped with Air
Suspension) for improved ground clearance. Traction
based tuning with improved steer-ability for use on
high traction off-road surfaces. Use for low speed
obstacles such as large rocks, deep ruts, etc. If
equipped with air suspension, the vehicle level will
change to Off-Road 2. If the Selec-Terrain switch is in

•Parking brake is released.
• Driver door is closed.
Activating HDC
Once HDC is enabled, it will activate automatically if
driven down a grade of sufficient magnitude. The set
speed for HDC is selectable by the driver, and can be
adjusted by using the gear shift +/-. The following
summarizes the HDC set speeds:
HDC Target Set Speeds
• P = No set speed. HDC may be enabled but will not
activate
• R = 0.6 mph (1 km/h)
• N = 1.2 mph (2 km/h)
• D = 0.6 mph (1 km/h)
• 1st = 0.6 mph (1 km/h) •
2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5.0 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped
NOTE: During HDC, the +/- shifter input is used for
HDC target speed selection but will not affect the gear
chosen by the transmission. When actively controlling
HDC, the transmission will shift appropriately for the
driver-selected set speed and corresponding driving con-
ditions.

Enabling SSC
SSC is enabled by pushing the SSC switch, but the
following conditions must also be met to enable SSC:
•Driveline is in 4WD Low Range.
• Vehicle speed is below 5 mph (8 km/h)
• Parking brake is released.
• Driver door is closed.
• Driver is not applying throttle.
Activating SSC
Once SSC is enabled it will activate automatically once
the following conditions are met:
• Driver releases throttle.
• Driver releases brake. •
Transmission is in any selection other than P.
• Vehicle speed is below 20 mph (32 km/h)
The set speed for SSC is selectable by the driver, and can
be adjusted by using the gear shift +/-. Additionally, the
SSC set speed may be reduced when climbing a grade
and the level of set speed reduction depends on the
magnitude of grade. The following summarizes the SSC
set speeds:
SSC Target Set Speeds
• 1st = .6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
526 STARTING AND OPERATING

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, you can use the
AutoStick shift control or manual gate of shifter to
manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions, will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking.
Autostick
• When using the AutoStick shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or
“3” if needed to maintain the desired speed.
• To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.
Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.

WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
•Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
• Turn on the Hazard Warning flasher.
• Chock the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set an automatic
transmission in PARK.
• Never start or run the engine with the vehicle on a
jack.
