2017 JEEP WRANGLER four wheel drive

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 (N) position without first fully engaging the
parking brake. The transfer case NEUTRAL (N) posi-
tion disengages both the front and rear drive shaft
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.
Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
2H Position
This range is used for normal street and highway driving
on hard-surfaced roads.
4H Position
This range locks the front and rear driveshafts together,
forcing the front and rear wheels to rotate at the same
speed. This range (4H) provides additional traction for
loose, slippery road surfaces and should not be used on dry
pavement.
The “4WD Indicator Light” (located in the instrument
cluster) will illuminate when the transfer case is shifted
into the 4H position.
N (Neutral) Position
This range disengages the front and rear driveshafts from
the powertrain. It is to be used for flat towing behind
another vehicle. Refer to “Recreational Towing” in “Start-
ing And Operating” for further information.
4L Position
This range locks the front and rear driveshafts together,
forcing the front and rear wheels to rotate at the same
speed. This range (4L) provides additional traction and
maximum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).

STARTING AND OPERATING 303

WARNING!
Do not disconnect the stabilizer bar and drive on
hard-surfaced roads or at speeds above 18 mph
(29 km/h); you may lose control of the vehicle, which
could result in serious injury. The front stabilizer bar
enhances vehicle stability and is necessary for main-
taining control of the vehicle. The system monitors
vehicle speed and will attempt to reconnect the stabi-
lizer bar at speeds over 18 mph (29 km/h). This is
indicated by a flashing or solid “Sway Bar Indicator
Light.” Once vehicle speed is reduced below 14 mph
(22 km/h), the system will once again attempt to return
to off-road mode.
To disconnect the stabilizer/sway bar, shift to either 4H or
4L and push the SWAY BAR switch to obtain the off-road
position. Refer to “Four-Wheel Drive Operation” in this
section for further information. The “Sway Bar Indicator
Light” will flash until the stabilizer/sway bar has been
fully disconnected. NOTE:
The stabilizer/sway bar may be torque locked due
to left and right suspension height differences. This condi-
tion is due to driving surface differences or vehicle loading.
In order for the stabilizer/sway bar to disconnect/
reconnect, the right and left halves of the bar must be
aligned. This alignment may require that the vehicle be
driven onto level ground or rocked from side to side.
To return to on-road mode, push the SWAY BAR switch
again.
WARNING!
If the stabilizer/sway bar will not return to on-road
mode, the “Sway Bar Indicator Light” will flash in the
instrument cluster and vehicle stability is greatly re-
duced. Do not attempt to drive the vehicle over 18 mph
(29 km/h). Driving faster than 18 mph (29 km/h) may
cause loss of control of the vehicle, which could result
in serious injury. Contact your local authorized dealer
for assistance.

Recreational Towing — Four-Wheel Drive Models
NOTE:The transfer case must be shifted into NEUTRAL
(N), automatic transmission must be in PARK, and manual
transmission must be in gear (NOT in NEUTRAL) for
recreational towing.
CAUTION!
• DO NOT dolly tow any 4WD vehicle. Towing with
only one set of wheels on the ground (front or rear)
will cause severe transmission and/or transfer case
damage. Tow with all four wheels either ON the
ground, or OFF the ground (using a vehicle trailer).
• Tow only in the forward direction. Towing this
vehicle backwards can cause severe damage to the
transfer case.
• Automatic transmissions must be placed in PARK
for recreational towing.
• Manual transmissions must be placed in gear (not in
Neutral) for recreational towing.
• Before recreational towing, perform the procedure
outlined under “Shifting Into NEUTRAL (N)” to be
certain that the transfer case is fully in NEUTRAL
(N). Otherwise, internal damage will result.
(Continued)
CAUTION! (Continued)
•Towing this vehicle in violation of the above require-
ments can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.
•
Do not use a bumper-mounted clamp-on tow bar on
your vehicle. The bumper face bar will be damaged.
Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for
recreational towing.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the NEU-
TRAL (N) position without first fully engaging the
parking brake. The transfer case NEUTRAL (N) position
disengages both the front and rear drive shaft from the
powertrain, and will allow the vehicle to roll, even if the
automatic transmission is in PARK (or manual transmis-
sion is in gear). The parking brake should always be
applied when the driver is not in the vehicle.

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
manufacturer ’s instructions. Use of safety chains is man-
datory. Attach a tow bar or other towing device to main
structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the vehicle’s battery is discharged, refer to “Gear Selector
Override” in this section for instructions on shifting the
automatic 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. Dam-
age to your vehicle may result from improper towing.
Without The Ignition Key
Special care must be taken when the vehicle is towed with
the ignition in the LOCK position. The only approved
method of towing without the ignition key is with a flatbed
truck. Proper towing equipment is necessary to prevent
damage to the vehicle.
Four–Wheel Drive Models
The manufacturer recommends towing with all wheels
OFF the ground. Acceptable methods are to tow the vehicle
on a flatbed or with one end of the vehicle raised and the
opposite end on a towing dolly.
If flatbed equipment is not available and the transfer case is
operable, the vehicle may be towed (in the forward direction,
with ALLwheels on the ground), IFthe transfer case is in
NEUTRAL (N) and the transmission is in PARK(for auto-
matic transmissions) or in gear ( NOTinNEUTRAL, for
manual transmissions). Refer to “Recreational Towing” in
“Starting And Operating” for detailed instructions.
366 IN CASE OF EMERGENCY

Refer to the “Maintenance Plan” for the proper mainte-
nance intervals. The reasons for any rapid or unusual wear
should be corrected prior to rotation being performed.
The suggested rotation method is the “rearward-cross”
shown in the following diagram.CAUTION!
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to
the transfer case. Tire rotation schedule should be
followed to balance tire wear.
DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire’s manufacturer in
each category is shown on the sidewall of the tires on your
vehicle.
All passenger vehicle tires must conform to Federal safety
requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on the
wear rate of the tire when tested under controlled condi-
tions on a specified government test course. For example, a
tire graded 150 would wear one and one-half times as well
on the government course as a tire graded 100. The relative
