2017 JEEP WRANGLER lock

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission 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 ignition must be turned to
the ON/RUN position (engine running or not) and the
brake pedal must be pressed.
Five-Speed Automatic Transmission — If Equipped
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
You must press the brake pedal to move the gear selector
out of PARK (refer to “Brake/Transmission Shift Interlock
System” in this section). To drive, move the gear selector
from PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual shifts can
be made using the Autostick shift control (refer to
AutoStick
in this section). Moving the gear selector to the
left or right (-/+) while in the DRIVE position will manu-
ally select the transmission gear and will display the
current gear in the instrument cluster as 1, 2, 3, etc.

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE:
•After selecting any gear range, wait a moment to allow
the selected gear to engage before accelerating. This is
especially important when the engine is cold.
• If there is a need to restart the engine, be sure to cycle the
ignition to the LOCK/OFF position before restarting.
Transmission gear engagement may be delayed after
restarting the engine if the ignition is not cycled to the
LOCK/OFF position first.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake. 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:
On four-wheel drive vehicles, 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
WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.

296 STARTING AND OPERATING

WARNING!(Continued)
•Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before leav-
ing the vehicle.
• 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 could accelerate quickly forward or in re-
verse. 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
running. Before exiting a vehicle always apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the ignition key.
Once the key is removed, the transmission is locked
in PARK, securing the vehicle against unwanted
movement.
(Continued)
WARNING! (Continued)
•When leaving the vehicle, always remove the igni-
tion key 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 unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission gear selector.
• Do not leave the ignition key in or near the vehicle
(or in a location accessible to children). A child could
operate power windows, other controls, or move the
vehicle.
CAUTION!
• Before moving the transmission gear selector out of
PARK, you must turn the ignition to the ON/RUN
mode, and also press the brake pedal. Otherwise,
damage to the gear selector could result.
• DO NOT race the engine when shifting from PARK
or NEUTRAL into another gear range, as this can
damage the drivetrain.

STARTING AND OPERATING 297

When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer to “AutoStick” in this section for further information)
to select a lower gear. Under these conditions, using a
lower gear will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will remain
in second gear regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to operate.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode allows the vehicle to be driven to an
authorized dealer for service without damaging the trans-
mission.In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition to the LOCK/OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your earliest
possible convenience. Your authorized dealer has diagnos-
tic equipment to determine if the problem could recur. If
the transmission cannot be reset, authorized dealer service
is required.6
STARTING AND OPERATING 299

The transfer case is intended to be driven in the 2H
position for normal street and highway conditions, such as
hard-surfaced roads.
In the event that additional traction is required, the transfer
case 4H and 4L positions can be used to lock the front and
rear driveshafts together, forcing the front and rear wheels
to rotate at the same speed. The 4H and 4L positions are
intended for loose, slippery road surfaces only and not
intended for normal driving. Driving in the 4H and 4L
positions on hard-surfaced roads will cause increased tirewear 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.
Four-Wheel Drive Gear Selector
302 STARTING AND OPERATING

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

Trac-Lok Rear Axle — If Equipped
The Trac-Lok rear axle provides a constant driving force to
both rear wheels and reduces wheel spin caused by the loss
of traction at one driving wheel. If traction differs between
the two rear wheels, the differential automatically propor-
tions the usable torque by providing more torque to the
wheel that has traction.
Trac-Lok is especially helpful during slippery driving
conditions. With both rear wheels on a slippery surface, a
slight application of the accelerator will supply maximum
traction.
WARNING!
On vehicles equipped with a limited-slip differential,
never run the engine with one rear wheel off the
ground. The vehicle may drive through the rear wheel
remaining on the ground and cause you to lose control
of your vehicle.
Axle Lock (Tru–Lok) — Rubicon Models
The AXLE LOCK switch is located on the instrument panel
(to the left of the steering column).This feature will only activate when the following condi-
tions are met:
•
Key in ignition, vehicle in 4L (Low) range.
• Vehicle speed should be 10 mph (16 km/h) or less.
To activate the system, push the bottom of the AXLE LOCK
switch once to lock the rear axle only (the “Rear Axle Lock
Indicator Light” will illuminate), push the bottom of the
switch again to lock the front axle (the “Front Axle Lock
Indicator Light” will illuminate). When the rear axle is
locked, pushing the bottom of switch again will lock or
unlock the front axle.

NOTE:The indicator lights will flash until the axles are
fully locked or unlocked.
To unlock the axles, push the top of the AXLE LOCK
switch.
Axle lock will disengage if the vehicle is taken out of 4L
(Low) range, or the ignition switch is turned to the OFF
position.
Electronic Sway Bar Disconnect — If Equipped
Your vehicle may be equipped with an electronic discon-
necting stabilizer/sway bar. This system allows greater
front suspension travel in off-road situations.
This system is controlled by the SWAY BAR switch located
on the instrument panel (to the left of the steering column). 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
illuminate when the bar is disconnected. The “Sway Bar
Indicator Light” will flash during activation transition, or
when activation conditions are not met. The stabilizer/
sway bar should remain in on-road mode during normal
driving conditions.
