2015 JEEP WRANGLER clutch

HSA On Manual Transmission Vehicles
The system will work in REVERSE, forward gears, and
NEUTRAL on manual transmission equipped vehicles.
The system does not recognize NEUTRAL on manual
vehicles, thus it will hold the vehicle on an incline for a
short period while in NEUTRAL, regardless of clutch
position. If the vehicle is pointed down hill in NEUTRAL
and your foot is not on the clutch, it will roll down hill,
HSA will not hold you in this case. To prevent this, do not
attempt to roll down a hill simply by putting the trans-
mission in NEUTRAL and letting gravity act on the
vehicle. Instead, use the appropriate gear for moving in
the desired direction.
NOTE:
Towing With HSA
HSA will provide assistance when starting on a grade
when pulling a trailer.
WARNING!
•If you use a trailer brake controller with your
trailer, your trailer brakes may be activated and
deactivated with the brake switch. If so, when the
brake pedal is released there may not be enough
brake pressure to hold the vehicle and trailer on a
hill and this could cause a collision with another
vehicle or object behind you. In order to avoid
rolling down the hill while resuming acceleration,
manually activate the trailer brake prior to releas-
ing the brake pedal. Always remember the driver is
responsible for braking the vehicle.
•HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.

474 STARTING AND OPERATING

WARNING!(Continued)
•Failure to follow these warnings may cause the
vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.
NOTE:The HSA system may also be turned on and off
if the vehicle is equipped with the Electronic Vehicle
Information Center (EVIC). Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
HSA Off
If you wish to turn off the HSA system, follow this
procedure:
1. Start with the engine off and vehicle in PARK (auto-
matic transmission) or NEUTRAL with clutch out
(manual transmission) with wheels straight. Apply
parking brake on manual transmission vehicle.
2. Start the engine.
3. With the engine running, the brake applied, and the
clutch out, rotate the steering wheel 180° counterclock-
wise from center.
4. Press the ESC OFF switch four times within twenty
seconds.
5. Rotate the steering wheel 360° clockwise (180° clock-
wise from center).
6. Cycle ignition switch OFF then ON.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, you can use the
AutoStick® shift control to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the trans-
mission fluid and filter as specified for#police, taxi, fleet,
or frequent trailer towing.#Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
NOTE:Check the automatic transmission fluid level
before towing.
AutoStick — If Equipped
•When using the AutoStick shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “4” if
the desired speed can be maintained. Choose “3” or
“2” if needed to maintain the desired speed.

STARTING AND OPERATING 551

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
NEUTRAL (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 transmission is in gear). The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop.
2. Press and hold the brake pedal.
3. Shift the automatic transmission into NEUTRAL or
depress the clutch pedal on a manual transmission.
4. Turn the engine OFF.
5. Shift the transfer case lever into NEUTRAL (N).
6. Start the engine.
7. Shift the transmission into REVERSE.

STARTING AND OPERATING 555

8. Release the brake pedal (and clutch pedal on manual
transmissions) for five seconds and ensure that there is
no vehicle movement.
9. Repeat Steps 7 and 8 with automatic transmission in
DRIVE or manual transmission in first gear.
10. Turn the engine OFF.
11. Firmly apply the parking brake.
12. Shift the transmission into PARK or place manual
transmission in gear (NOT in NEUTRAL).
CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into PARK with the transfer case in
NEUTRAL (N) and the engine running. With the
transfer case in NEUTRAL (N) ensure that the engine
is OFF before shifting the transmission into PARK.
13. Attach the vehicle to the tow vehicle using a suitable
tow bar.
14. Release the parking brake.
Shifting Out of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring the vehicle to a complete stop, leaving it con-
nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Turn the ignition switch to the LOCK position.
4. Turn the ignition switch to the ON/RUN position, but
do not start the engine.
5. Press and hold the brake pedal.
6. Shift the transmission into NEUTRAL.
556 STARTING AND OPERATING

7. Shift the transfer case lever to the desired position.
NOTE:When shifting the transfer case out of NEUTRAL
(N), the engine should remain OFF to avoid gear clash.
8. Shift the automatic transmission into PARK, or place
manual transmission in NEUTRAL.
9. Release the brake pedal.
10. Disconnect vehicle from the tow vehicle.
11. Start the engine.
12. Press and hold the brake pedal.
13. Release the parking brake.
14. Shift the transmission into gear, release the brake
pedal (and clutch pedal on manual transmissions),
and check that the vehicle operates normally.

STARTING AND OPERATING 557

CAUTION!(Continued)
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE
and REVERSE (with automatic transmission) or 2nd gear
and REVERSE (with manual transmission), while gently
pressing the accelerator. Use the least amount of accel-
erator pedal pressure that will maintain the rocking
motion, without spinning the wheels, or racing the
engine.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
NOTE:Press the#ESC Off#switch, to place the Electronic
Stability Control (ESC) system in#Partial Off#mode,
before rocking the vehicle. Refer to “Electronic Brake
Control” in “Starting And Operating” for further infor-
mation. Once the vehicle has been freed, press the#ESC
Off#switch again to restore#ESC On#mode.
