2019 JEEP WRANGLER UNLIMITED ECO mode

Stopping the Engine
The following chart should be used as a guide
in determining the amount of engine idle
time required to sufficiently cool down the
turbocharger before shut down, depending
upon the type of driving and the amount of
cargo.Before turning off your turbo diesel engine,
always allow the engine to return to normal idle
speed and run for several seconds. This assures
proper lubrication of the turbocharger. This is
particularly necessary after any period of hard
driving.
Idle the engine a few minutes before routine
shutdown. After full load operation, idle theengine three to five minutes before shutting it
down. This idle period will allow the lubricat-
ing oil and coolant to carry excess heat away
from the combustion chamber, bearings, in-
ternal components, and turbocharger. This is
especially important for turbocharged,
charge air cooled engines.

ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle.Drive moderately during the first 300 miles
(500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.While cruising, brief full-throttle acceleration
within the limits of local traffic laws contrib-
utes to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental
and should be avoided.
STARTING AND OPERATING
146

• You can start out, from a stop, in first or
second gear (or third gear, in 4LO range).
Tapping (+) (at a stop) will allow starting in
second gear. Starting out in second or third
gear can be helpful in snowy or icy condi-
tions.
• If a requested downshift would cause the
engine to over-speed, that shift will not
occur.
• The system will ignore attempts to upshift
at too low of a vehicle speed.
• Holding the gear selector in the (-) position
will downshift the transmission to the low-
est gear possible at the current speed.
• Transmission shifting will be more notice-
able when AutoStick is enabled.
• The system may revert to automatic shift
mode if a fault or overheat condition is
detected.
NOTE:
When Hill Descent Control is enabled,
AutoStick is not active.To disengage AutoStick mode, return the gear
selector to the DRIVE position. You can shift
in or out of the AutoStick position at any time
without taking your foot off the accelerator
pedal.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the ve-
hicle could skid, causing a collision or
personal injury.
FOUR–WHEEL DRIVE
OPERATION
WARNING!
Failure to engage a transfer case position
completely can cause transfer case dam-
age or loss of power and vehicle control.
You could have a collision. Do not drive the
vehicle unless the transfer case is fully
engaged.
Four-Position Transfer Case
The transfer case provides four mode posi-
tions:
• 2H (Two-Wheel Drive High Range)
• 4H (Four-Wheel Drive High Range)
• N (Neutral)
• 4L (Four-Wheel Drive Low Range)

speed. This range provides additional trac-
tion and maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
This transfer case is designed to be driven in
the two-wheel drive position (2WD) or four-
wheel drive position (4WD AUTO) for normal
street and highway conditions on dry hard
surfaced roads. Driving the vehicle in 2WD
will have greater fuel economy benefits as the
front axle is not engaged in 2WD.
For variable driving conditions, the 4WD
AUTO mode can be used. In this mode, the
front axle is engaged, but the vehicle's power
is sent to the rear wheels. Four-wheel drive
will be automatically engaged when the ve-
hicle senses a loss of traction. Because the
front axle is engaged, this mode will result in
lower fuel economy than the 2WD mode.
In the event that additional traction is re-
quired, the transfer case 4H and 4L positions
can be used to lock the front and rear drive-
shafts together, forcing the front and rear
wheels to rotate at the same speed. The 4H
and 4L positions are intended for loose, slip-
pery road surfaces only and not intended fornormal driving. Driving in the 4H and 4L
positions on hard-surfaced roads will cause
increased tire wear and damage to the drive-
line components. Refer to “Shifting Proce-
dures” in this section for further information
on shifting into 4H or 4L.
The instrument cluster alerts the driver that
the vehicle is in four-wheel drive, and the
front and rear driveshafts are locked together.
The light will illuminate when the transfer
case is shifted into the 4H position.
When operating your vehicle in 4L, the en-
gine 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 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.Shifting Procedures
2H To 4H Auto Or 4H Auto To 2H
Shifting between 2H and 4H Auto can be
made with the vehicle stopped or in motion.
The preferred shifting speed would be 0 to
45 mph (72 km/h). With the vehicle in mo-
tion, the transfer case will engage/disengage
faster if you momentarily release the accel-
erator pedal after completing the shift. Do
not accelerate while shifting the transfer
case. Apply a constant force when shifting
the transfer case lever.
2H/4H Auto To 4H Part Time Or 4H Part Time
To 2H/4H Auto
Shifting between 2H/4H AUTO to 4H PART
TIME can be made with the vehicle stopped
or in motion. The preferred shifting speed
would be 0 to 45 mph (72 km/h). With the
vehicle in motion, the transfer case will
engage/disengage faster if you momentarily
release the accelerator pedal after complet-
ing the shift. Do not accelerate while shifting
the transfer case. Apply a constant force
when shifting the transfer case lever.
STARTING AND OPERATING
154

Push the SWAY BAR switch to activate the
system. Push the switch again to deactivate
the system. The “Sway Bar Indicator Light”
(located in the instrument cluster) will illumi-
nate when the bar is disconnected. The
“Sway Bar Indicator Light” will flash during
activation transition, or when activation con-
ditions are not met. The stabilizer/sway bar
should remain in on-road mode during nor-
mal driving conditions.
WARNING!
Ensure the stabilizer/sway bar is recon-
nected before driving on hard surfaced
roads or at speeds above 18 mph
(29 km/h); a disconnected stabilizer/sway
bar may contribute to the loss of vehicle
control, which could result in serious in-
jury. Under certain circumstances, the
front stabilizer/sway bar enhances vehicle
stability and assists with vehicle control.
The system monitors vehicle speed and
will attempt to reconnect the stabilizer/
sway bar at speeds over 18 mph
(29 km/h). This is indicated by a flashing
or solid “Sway Bar Indicator Light.” Once
WARNING!
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 sec-
tion 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 differ-
ences. This condition is due to driving sur-
face 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 may be reduced. Do
not attempt to drive the vehicle over
18 mph (29 km/h). Driving faster than
18 mph (29 km/h) with a disconnected
stabilizer/sway bar may contribute to the
loss of vehicle control, which could result
in serious injury.
STOP/START SYSTEM —
AUTOMATIC
TRANSMISSION (IF
EQUIPPED)
The Stop/Start function is developed to re-
duce fuel consumption. The system will stop
the engine automatically during a vehicle
stop if the required conditions are met. Re-
leasing the brake pedal or pressing the accel-
erator pedal will automatically re-start the
engine.

It is recommended that the Start/Stop Sys-
tem be disabled during off-road use.
Automatic Mode
The Stop/Start feature is enabled
after every normal customer en-
gine start. At that time, the sys-
tem will go into STOP/START
READY and if all other conditions are met,
can go into a STOP/START AUTOSTOP AC-
TIVE “Autostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
• The system must be in STOP/START
READY state. A STOP/START READY mes-
sage will be displayed in the instrument
