2017 JEEP GRAND CHEROKEE engine

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 NEU-
TRAL position without first fully engaging the park-
ing brake. The transfer case NEUTRAL position disen-
gages 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.

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” further on in
this section for further information on the various positions
and their intended usages.
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 Operating” for
further information.
WARNING!

the parking brake. The NEUTRAL (N) position disen-
gages 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.
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, slip-
pery 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.

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 instrument
cluster display. Refer to “Instrument Cluster Display” in
“Getting To Know 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 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.

Automatic lowering of the vehicle into Entry/Exit
Mode can be enabled through the Uconnect Touch-Screen
Radio. If this feature is enabled, the vehicle will only lower
if the gear selector is in PARK, the terrain switch is in
AUTO, the transfer-case is in AUTO” and the vehicle
level should be either in Normal or Aero Mode. The Vehicle
will not automatically lower if the air suspension level is in
Off Rd 2 or Off Rd 1. If the vehicle is equipped with
Intrusion Theft Module (ITM), the lowering will be sup-
pressed when the ignition is switched OFF and the door is
open to prevent setting the alarm off.
The Selec-Terrain switch will automatically change the
vehicle to the proper height based on the position of the
Selec-Terrain switch. The height can be changed from the
default Selec-Terrain setting by normal use of the air
suspension buttons. Refer to “Selec-Terrain” in “Starting
And Operating” for further information.
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. If a door is opened at
any time while the vehicle is lowering the change will not
be completed until the open door(s) is closed.
290 STARTING AND OPERATING

The Quadra-Lift air suspension system uses a lifting and
lowering pattern which keeps the headlights from incor-
rectly shining 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, it may be noticed that the air
suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.
To assist with changing a spare tire, the Quadra-Lift air
suspension system has a feature which allows the auto-
matic leveling to be disabled. Refer to “Uconnect Settings”
in “Multimedia” for further information.
NOTE:If equipped with a touch screen radio all enabling/
disabling of air suspension features must be done through
the radio. Refer to “Uconnect Settings” in “Multimedia” for
further information.
WARNING!
The air suspension system uses a high pressure vol-
ume of air to operate the system. To avoid personal

Operation
The indicator lamps 3 through 6 will illuminate to show the
current position of the vehicle. Flashing indicator lamps
will show a position which the system is working to
achieve. When raising, if multiple indicator lamps are
flashing on the “Up” button, the highest flashing indicator
lamp is the position the system is working to achieve. When lowering, if multiple indicators are flashing on the
Up
button the lowest solid indicator lamp is the position
the system is working to achieve.
Pushing the “UP” button once will move the suspension
one position higher from the current position, assuming all
conditions are met (i.e. engine running, speed below
threshold, etc). The “UP” button can be pushed multiple
times, each push will raise the requested level by one
position up to a maximum position of OR2 or the highest
position allowed based on current conditions (i.e. vehicle
speed, etc).
Pushing the “DOWN” button once will move the suspen-
sion one position lower from the current level, assuming all
conditions are met (i.e. engine running, doors closed, speed
below threshold, etc). The “DOWN” button can be pressed
multiple times. Each push will lower the requested level by
one position down to a minimum of Park Mode or the
lowest position allowed based on current conditions (i.e.
vehicle speed, etc.)
Automatic height changes will occur based on vehicle
speed and the current vehicle height. The indicator lamps
and instrument cluster display messages will operate the
same for automatic changes and user requested changes.
292 STARTING AND OPERATING

•Off-Road 2 (OR2) – Indicator lamps 4, 5, and 6 will be
illuminated when the vehicle is in OR2.
• Off-Road 1 (OR1) – Indicator lamps 4 and 5 will be
illuminated when the vehicle is in OR1.
• Normal Ride Height (NRH) – Indicator lamp 4 will be
illuminated when the vehicle is in this position.
• Entry/Exit Mode – Indicator lamp 3 will be illuminated
when the vehicle is in Entry/Exit Mode. If Entry/Exit
Mode is requested while vehicle speed is between 15
mph (24 km/h) and 25 mph (40 km/h), indicator lamp 4
will remain on solid and indicator lamp 3 will flash as
the system waits for the vehicle to reduce speed. If
vehicle speed is reduced to, and kept below, 15 mph
(24 km/h) indicator lamp 4 will turn off and indicator
lamp 3 will flash until Entry/Exit Mode is achieved at
which point indicator lamp 3 will go solid. If during the
height change to Entry/Exit Mode, the vehicle speed
exceeds 15 mph (24 km/h), the height change will be
paused until the vehicle speed either goes below 15 mph
(24 km/h) and the height change continues to Entry/
Exit Mode, or exceeds 25 mph (40 km/h) and the vehicle
height will return to NRH. Entry/Exit Mode may be
selected while the vehicle is not moving provided that
the engine is still running and all doors remain closed. •
