2016 JEEP GRAND CHEROKEE air suspension

Shifting Procedures
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the
ON/RUN 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 begin to flash and remain on solid when
the shift is complete.
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/RUN 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 turn off when the shift is
complete.
NOTE:
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 properly
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.
NEUTRAL Shift Procedure
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 transfer case NEUTRAL (N) position disengages both the front and rear
driveshafts 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.
4. If vehicle is equipped with Quadra-Lift air suspension, ensure the vehicle is set to Normal Ride Height.

SELEC-TERRAIN
Selec-Terrain combines the capabilities of the vehicle control systems, along with
driver input, to provide the best performance for all terrains.
Rotate the mode control knob to select the following Selec-Terrain 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 suspension, the
level will change to Normal Ride Height (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 improved 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 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
NRH.
OFF-ROAD CAPABILITIES (4WD OPERATION)

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. Activate the Hill
Descent Control for steep downhill control. 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 ROCK mode, and the transfer case is
switched from 4WD Low to 4WD High, the Selec-Terrain system will return to AUTO.
QUADRA-LIFT
The Quadra-Lift air suspension system provides full time load leveling capability
along with the benefit of being able to adjust vehicle height by the push of a button.
Quadra-Lift is available with both Quadra-Trac II and Quadra-Drive II.
• The system requires that the engine be running for all changes. When lowering
the vehicle all of the doors, including
the liftgate, must be closed.
• The Quadra-Lift air suspension system uses a lifting and lowering pattern
which keeps the headlights from shin-
ing into oncoming traffic. When raising
the vehicle, the rear of the vehicle will
move up first and then the front. When
lowering the vehicle, the front will
move down first and then the rear.
• After the engine is turned off, you may notice that the air suspension system
operates briefly. This is normal. The
system is correcting the position of the
vehicle.
• To assist with changing a spare tire, the Quadra-Lift air suspension system
has a feature which allows the automatic leveling to be disabled. The feature
controls are located in the radio screen. Driving the vehicle over 5 mph (8 km/h)
will return the air suspension to normal operation.
• An audible chime will be heard whenever a system error has been detected.

• Aero Mode (Lowers the vehicle approximately 0.6 in (15 mm) – This positionprovides improved aerodynamics by lowering the vehicle. The vehicle will auto-
matically enter Aero Mode when the vehicle speed remains between 52 mph
(83 km/h) and 56 mph (90 km/h) for greater than 20 seconds or if the vehicle
speed exceeds 56 mph (90 km/h). The vehicle will return to NRH from Aero Mode
if the vehicle speed remains between 20 mph (32 km/h) and 25 mph (40 km/h) for
greater than 20 seconds or if the vehicle speed falls below 20 mph (32 km/h). The
vehicle will enter Aero Mode, regardless of vehicle speed if the gear selector is in
the “SPORT” position.
• Transport Mode — To assist with flat bed towing, the air suspension system has a feature which will put the vehicle into Entry/Exit height and disable the automatic
load leveling system. Refer to “Programmable Features" (Uconnect Customer
Programmable Features) in “Electronics” for further information. Transport Mode
is selectable within the Suspension features.
NOTE:
This mode is intended to be enabled with engine running.
WARNING!
• You or others could be injured if you leave the vehicle unattended with the transfer case in the N (Neutral) position without first fully engaging the parking
brake. The transfer case N (Neutral) position disengages both the front and rear
driveshafts 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.
• The air suspension system uses a high pressure volume of air to operate the
system. To avoid personal injury or damage to the system, see your authorized
dealer for service.
HILL START ASSIST/HILL DESCENT CONTROL/SELEC
SPEED CONTROL — IF EQUIPPED
• The Hill Start Assist system assists the driver when starting a vehicle from a stopon a hill.
• The Hill Descent Control system maintains vehicle speed while descending hills during off-road driving situations and is available in 4WD LOW range.
• The Selec Speed Control feature allows the driver to travel at slow speeds on level ground, uphill or downhill without actively controlling either the throttle or brake.
• Refer to your Owner's Manual on the DVD for further details.

14. Attach the vehicle to the tow vehicle using a suitable tow bar.
15. Release the parking brake.
NOTE:
• Steps 1 through 4 are requirements that must be met before pressing the NEUTRAL (N) button, and must continue to be met until the shift has been
completed. If any of these requirements are not met before pushing the NEUTRAL
(N) button or are no longer met during the shift, then the NEUTRAL (N) indicator
light will flash continuously until all requirements are met or until the NEUTRAL
(N) button is released.
• The ignition switch must be in the ON/RUN position for a shift to take place and for the position indicator lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no position indicator lights will
be on or flashing.
• A flashing NEUTRAL (N) position indicator light indicates that shift requirements have not been met.
• If the vehicle is equipped with Quadra-Lift air suspension, the engine should be started and left running for a minimum of 60 seconds (with all the doors closed)
at least once every 24 hours. This process allows the air suspension to adjust the
vehicle’s ride height to compensate for temperature effects.
