transmission JEEP WRANGLER UNLIMITED 2018 Owner handbook (in English)

• As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’s instructions for cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor
(If Equipped)
• Flash hazard lights as long as the battery
has power
• Turn on the interior lights, which remain on
as long as the battery has power or for 15
minutes from the intervention of the En-
hanced Accident Response System.
• Unlock the power door locks.Your vehicle may also be designed to perform
any of these other functions in response to
the Enhanced Accident Response System:
• Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circu-
lation Door
• Cut off battery power to the:
– Engine
– Electric Motor (if equipped)
– Electric power steering
– Brake booster
– Electric park brake
– Automatic transmission gear selector
– Horn
– Front wiper
– Headlamp washer pump
NOTE:
After an accident, remember to cycle the
ignition to the STOP (OFF/LOCK) position
and remove the key from the ignition switch
to avoid draining the battery. Carefully check
the vehicle for fuel leaks in the engine com-
partment and on the ground near the engine
compartment and fuel tank before resetting
the system and starting the engine. If there
are no fuel leaks or damage to the vehicle

AutoPark
AutoPark is a supplemental feature to assist
in placing the vehicle in PARK should the
situations on the following pages occur. It is a
back up system and should not be relied upon
as the primary method by which the driver
shifts the vehicle into PARK.
The conditions under which AutoPark will
engage are outlined on the following pages.
WARNING!
• Driver inattention could lead to failure to
place the vehicle in PARK. ALWAYS DO
A VISUAL CHECK that your vehicle is in
PARK by verifying that a solid (not blink-
ing) “P” is indicated in the instrument
cluster display and on the gear selector.
If the "P" indicator is blinking, your ve-
hicle is not in PARK. As an added pre-
caution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is
not designed to replace the need to shift
your vehicle into PARK. It is a back up
system and should not be relied upon as
the primary method by which the driver
shifts the vehicle into PARK.
If the vehicle is not in PARK and the driver turns
off the engine, the vehicle may AutoPark.
AutoPark will engage when all of these con-
ditions are met:
• Vehicle is equipped with an 8-speed trans-
mission
143

• Drivers door is ajar or in conditions where
driver door is removed an additional trigger
would be if the driver is off the seat (seat
pad sensor detects driver missing).
• Vehicle is not in PARK
• Vehicle Speed is 0 mph (0 km/h)
• Ignition switched from RUN to OFF
NOTE:
For Keyless Go equipped vehicles, The en-
gine will turn off and the ignition switch will
change to ACC mode. After 30 minutes the
ignition switches to OFF automatically, un-
less the driver turns the ignition switch OFF.
If the vehicle is not in PARK and the driver exits
the vehicle with the engine running, the vehicle
may AutoPark.
AutoPark will engage when all of these con-
ditions are met:
• Vehicle is equipped with an 8-speed trans-
mission
• Drivers door is ajar or in conditions where
driver door is removed an aditional trigger
would be if the driver is off the seat (seat
pad sensor detects driver missing).• Vehicle is not in PARK
• Driver’s door is removed
• Vehicle speed is 1.2 mph (2.0 km/h) or less
• Driver’s seat belt is unbuckled
• Driver’s door is ajar
• Brake Pedal is not depressed
The MESSAGE “AutoPark Engaged Shift to P
then Shift to Gear” will display in the instru-
ment cluster.
NOTE:
In some cases the ParkSense graphic will be
displayed in the instrument cluster. In these
cases, the shifter must be returned to “P” to
select desired gear.
If the driver shifts into PARK while moving, the
vehicle may AutoPark.
AutoPark will engageONLYwhen vehicle
speed is 1.2 mph (2.0 km/h) or less.
The MESSAGE “Vehicle Speed is Too High to
Shift to P” will be displayed in the instrument
cluster if vehicle speed is above 1.2 mph
(2.0 km/h).WARNING!
If vehicle speed is above 1.2 mph
(2.0 km/h), the transmission will default
to NEUTRAL until the vehicle speed drops
below 1.2 mph (1.9 km/h). A vehicle left
in the NEUTRAL position can roll. As an
added precaution, always apply the park-
ing brake when exiting the vehicle.
4WD LOW
AutoPark will be disabled when operating the
vehicle in 4WD LOW.
The MESSAGE “AutoPark Disabled” will be
displayed in the instrument cluster.
Additional customer warnings will be given
when both of these conditions are met:
• Vehicle is not in PARK
• Driver’s Door is ajar
The MESSAGE “AutoPark Not Engaged” will
be displayed in the instrument cluster. A
warning chime will continue until you shift
the vehicle into PARK or the Driver’s Door is
closed.
STARTING AND OPERATING

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

The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. For
the recommended viscosity and quality
grades, refer to “Fluids And Lubricants” in
“Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as a problem.
AUTOMATIC
TRANSMISSION
CAUTION!
Damage to the transmission may occur if
the following precautions are not ob-
served:
• Shift into or out of PARK or REVERSE
only after the vehicle has come to a
complete stop.
• Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
• Before shifting into any gear, make sure
your foot is firmly pressing the brake
pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
WARNING!
• Never use the PARK position as a sub-
stitute for the parking brake. Always ap-
WARNING!
ply the parking brake fully when exiting
the vehicle to guard against vehicle
movement and possible injury or dam-
age.
• Your vehicle could move and injure you
and others if it is not in PARK. Check by
trying to move the transmission gear
selector out of PARK with the brake
pedal released. Make sure the transmis-
sion is in PARK before exiting the ve-
hicle.
• The transmission may not engage PARK
if the vehicle is moving. Always bring the
vehicle to a complete stop before shift-
ing to PARK, and verify that the trans-
mission gear position indicator solidly
indicates PARK (P) without blinking. En-
sure that the vehicle is completely
stopped, and the PARK position is prop-
erly indicated, before exiting the ve-
hicle.
• It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle
147

WARNING!
could accelerate quickly forward or in
reverse. You could lose control of the
vehicle and hit someone or something.
Only shift into gear when the engine is
idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle
could injure those in or near the vehicle.
As with all vehicles, you should never
exit a vehicle while the engine is run-
ning. Before exiting a vehicle, always
come to a complete stop, then apply the
parking brake, shift the transmission
into PARK, and turn the ignition OFF.
When the ignition is in the OFF mode,
the transmission is locked in PARK, se-
curing the vehicle against unwanted
movement.
• When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle un-
WARNING!
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to
children), and do not leave the ignition
in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
Ignition Park Interlock
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to
be in PARK before the ignition can be turned
to the OFF mode. This helps the driver avoid
inadvertently leaving the vehicle without
placing the transmission in PARK. This sys-
tem also locks the transmission in PARK
whenever the ignition is in the OFF mode.NOTE:
The transmission is NOT locked in PARK
when the ignition is in the ACC mode (even
though the engine will be off). Ensure that
the transmission is in PARK, and the ignition
isOFF(not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must
be running and the brake pedal must be
pressed. The brake pedal must also be
pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or
moving at low speeds.
Eight–Speed Automatic Transmission
Your vehicle is equipped with a fuel efficient
8 speed transmission. The gear selector is
located in the center console.
STARTING AND OPERATING
148

The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE and
MANUAL (AutoStick) shift positions. Manual
shifts can be made using the AutoStick shift
control. Toggling the gear selector forward (-)
or rearward (+) while in the MANUAL
(AutoStick) position (beside the DRIVE posi-
tion) will manually select the transmission
gear, and will display the current gear in the
instrument cluster. Refer to "AutoStick" in
this section for further information.NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position
(when pushed forward), it is probably in the
AutoStick (+/-) position (beside the DRIVE
position). In AutoStick mode, the transmis-
sion gear (1, 2, 3, etc.) is displayed in the
instrument cluster. Move the gear selector to
the right (into the DRIVE [D] position) for
access to PARK, REVERSE, and NEUTRAL.
AutoStick
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving
you more control of the vehicle. AutoStick
allows you to maximize engine braking, elimi-
nate undesirable upshifts and downshifts,
and improve overall vehicle performance.
This system can also provide you with more
control during passing, city driving, cold slip-
pery conditions, mountain driving, trailer
towing, and many other situations.
Operation
To activate AutoStick mode, move the gear
selector into the MANUAL (M) position (be-
side the DRIVE position). The current trans-mission gear will be displayed in the instru-
ment cluster. In AutoStick mode, you can use
the gear selector (in the MANUAL position) to
manually shift the transmission. Tapping the
gear selector forward (-) while in the
MANUAL (M) position will downshift the
transmission to the next lower gear. Tapping
the selector rearward (+) will command an
upshift.
In AutoStick mode, the transmission will
shift up or down when (+/-) is manually se-
lected by the driver, unless an engine lugging
or overspeed condition would result. It will
remain in the selected gear until another
upshift or downshift is chosen, except as
described below.
• The transmission will automatically down-
shift as the vehicle slows (to prevent engine
lugging) and will display the current gear.
• The transmission will automatically down-
shift to first gear when coming to a stop.
After a stop, the driver should manually
upshift (+) the transmission as the vehicle
is accelerated.
Transmission Gear Selector
149

• 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)
