2017 JEEP GRAND CHEROKEE 4WD

Quadra-Trac II Operating Instructions/
Precautions — If Equipped
The Quadra-Trac II transfer case is fully au-
tomatic in the normal driving 4WD AUTO
mode. The Quadra-Trac II transfer case pro-
vides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
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 in-
tended 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 dam-
age 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 parking
brake. The transfer case NEUTRAL posi-
tion disengages both the front and rear
drive shafts from the powertrain and will
allow the vehicle to roll, even if the trans-
mission is in PARK. The parking brake
WARNING!
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” fur-
ther 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 “Recre-
ational Towing” in “Starting And Operating”
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 transmission
is in PARK. The parking brake should al-
ways 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
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 posi-
tion or the engine running, shift the transmis-
sion into “N”, and push 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.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 instru-
ment cluster display. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
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 posi-
tion or the engine running, shift the transmis-
sion into NEUTRAL, and push 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 pro-
tection 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 “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
• Shifting into or out of 4WD LOW is pos- sible 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.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 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.
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.
5. Using a ballpoint pen or similar object, push and hold the recessed transfer case
NEUTRAL (N) button (located by the se-
lector switch) for four seconds. The light behind the NEUTRAL (N) symbol will
blink, indicating shift in progress. The
light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is com-
plete. A “NEUTRAL” message will appear
in the instrument cluster display. Refer to
“Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for fur-
ther information.
6. After the shift is completed and the NEU- TRAL (N) light stays on, release the NEU-
TRAL (N) button.
7. Shift the transmission into REVERSE.

SELEC-TERRAIN — IF
EQUIPPED
Selec-Terrain Mode Selection
Selec-Terrain combines the capabilities of
the vehicle control systems, along with driver
input, to provide the best performance for all
terrains. Selec-Terrain consists of the following posi-
tions:
•
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 cer-
tain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage. If equipped with air suspension,
the default ride height for Snow is 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 ve-
hicles. If equipped with air suspension,
the level will change to Normal Ride
Height (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 default ride
height for Sand is Normal Ride Height
(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 sus-
pension, 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 im-
proved 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 sus-
pension, 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.

TOWING A DISABLED
VEHICLE
This section describes procedures for towing
a disabled vehicle using a commercial towing
service. If the transmission and drivetrain are
operable, disabled vehicles may also be
towed as described under “Recreational Tow-
ing” in “Starting and Operating”.NOTE:
Vehicles equipped with Quadra-Lift must be
placed in Transport mode, before tying them
down (from the body) on a trailer or flatbed
truck. Refer to “Quadra-Lift” in “Starting and
Operating” for more information. If the ve-
hicle cannot be placed in Transport mode (for
example, engine will not run), tie-downs must
be fastened to the axles (not to the body).

wheelsOFFthe ground.
Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
device to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
If the key fob is unavailable, or the vehicle's
battery is discharged, refer to “Manual Park
Release” in this section for instructions on
shifting the transmission out of PARK for
towing.CAUTION!
• Do not use sling type equipment when towing. Vehicle damage may occur.
• When securing the vehicle to a flat bed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your
vehicle with all four wheels OFFthe ground
using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
towed (with rear wheels on the ground) under
the following conditions:
• The transmission must be in NEUTRAL. Refer to "Manual Park Release" in this
section for instructions on shifting the
transmission to NEUTRAL when the en-
gine is off.
• The towing speed must not exceed 30 mph (48 km/h). • The towing distance must not exceed
30 miles (48 km).
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km),
tow with the rear wheels OFFthe ground.
Acceptable methods are to tow the vehicle on
a flatbed, or with the front wheels raised and
the rear wheels on a towing dolly, or (when
using a suitable steering wheel stabilizer to
hold the front wheels in the straight position)
with the rear wheels raised and the front
wheels on the ground.
CAUTION!
Towing faster than 30 mph (48 km/h) or
farther than 30 miles (48 km) with rear
wheels on the ground can cause severe
transmission damage. Damage from im-
proper towing is not covered under the
New Vehicle Limited Warranty.
