DIFF JEEP WRANGLER JK 2018 Owners Manual

When inESC Full Off mode, ESC and TCS, except for the
Brake Limited Differential (BLD) feature described in the
TCS section, are turned off until the vehicle reaches an
approximate speed of 40 mph (64 km/h). For speeds at or
exceeding approximately 40 mph (64 km/h) the ESC goes
into ESC Partial Off. When the vehicle speed drops below
35 mph (56 km/h), the ESC system goes back to ESC Full
Off. To turn ESC on again, momentarily push the ESC OFF
switch. This will restore normal “ESC On” mode of opera-
tion. The ESC Off Indicator Light” will always be illumi-
nated when ESC is in ESC Partial OffandESC full Off.

When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
•When the parking brake is applied and the automatic
transmission is placed in gear, the “Brake Warning
Light” will flash. If vehicle speed is detected, a chime
will sound to alert the driver. Fully release the parking
brake before attempting to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application. When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. For vehicles equipped
with an automatic transmission, apply the parking brake
before placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.

When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on
the transmission locking mechanism may make it difficult
to move the gear selector out of PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill grade.
NOTE:Be sure that the transfer case is in a drive position.
When exiting the vehicle, always:
• Apply the parking brake
• Shift the transmission into PARK
• Turn the engine OFF
• Remove the ignition key

wear and damage to the driveline components. Refer to
“Shifting Procedures” in this section for further informa-
tion on shifting into 4H or 4L.
The “4WD Indicator Light” (located in the instrument
cluster) alerts the driver that the vehicle is in four-wheel
drive, and the front and rear driveshafts are locked to-
gether. The light will illuminate when the transfer case is
shifted into the 4H position.
NOTE:Do not attempt to shift when only the front or rear
wheels are spinning. The transfer case is not equipped with
a synchronizer, and the front and rear driveshaft speeds
must be equal for a shift to take place. Shifting while the
front or rear wheels are spinning at different speeds can
cause damage to the transfer case.
When operating your vehicle in 4L, the engine speed will
be approximately three times (four times for Rubicon
models) that of the 2H or 4H positions at a given road
speed. Take care not to overspeed the engine.
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.

4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift an
automatic transmission into NEUTRAL (N), or press the
clutch pedal on a manual transmission. While the vehicle is
coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case
lever firmly to the desired position. Do not pause with the
transfer case in N (Neutral). Once the shift is completed,
place the automatic transmission into DRIVE or release the
clutch pedal on a manual transmission.
NOTE:Shifting into or out of 4L is possible with the
vehicle completely stopped; however, difficulty may occur
due to the mating 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 at 2 to 3 mph (3 to 5 km/h). Avoid
attempting to engage or disengage 4L with the vehicle
moving faster than 2 to 3 mph (3 to 5 km/h).

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.

Crossing Obstacles (Rocks And Other High Points)
While driving off-road, you will encounter many types of
terrain. These varying types of terrain bring different types
of obstacles. Before proceeding, review the path ahead to
determine the correct approach and your ability to safely
recover the vehicle if something goes wrong. Keeping a
firm grip on the steering wheel, bring the vehicle to a
complete stop and then inch the vehicle forward until it
makes contact with the object. Apply the throttle lightly
while holding a light brake pressure and ease the vehicle
up and over the object.

Crossing Puddles, Pools, Flooded Areas Or Other
Standing Water
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to
entering. This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.

WARNING!
Do not plug in or remove the iPod or external device
while driving. Failure to follow this warning could
result in a collision.
