JEEP WRANGLER UNLIMITED 2013 Owners Manual

Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package will include a four–pin wiring
harness. Use a factory-approved trailer harness and
connector.
NOTE: Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustration. Four-Pin Connector1 — Female Pins 4 — Park
2 — Male Pin 5 — Left Stop/Turn
3 — Ground 6 — Right Stop/Turn

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. How-
ever, if frequent shifting occurs while in this range, use
the Electronic Range Select (ERS) shift control to select a
lower gear range. NOTE: Using a lower gear range while operating the
vehicle under heavy loading conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the transmis-
sion 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.530 STARTING AND OPERATING

Electronic Speed Control – If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency. Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

Recreational Towing – Four-Wheel Drive Models
NOTE: The transfer case must be shifted into NEUTRAL
(N), automatic transmission must be shifted into PARK,
and manual transmission must be placed in gear (NOT in
NEUTRAL) for recreational towing.
CAUTION!• Front or rear wheel lifts should not be used. Inter-
nal damage to the transmission or transfer case will
occur if a front or rear wheel lift is used when
recreational towing.
• Tow only in the forward direction. Towing this
vehicle backwards can cause severe damage to the
transfer case.
• Automatic transmissions must be placed in the
PARK position for recreational towing. (Continued) CAUTION! (Continued)• Manual transmissions must be placed in gear (not
in Neutral) for recreational towing.
• Before recreational towing, perform the procedure
outlined under “Shifting Into NEUTRAL (N)” to be
certain that the transfer case is fully in NEUTRAL
(N). Otherwise, internal damage will result.
• Towing this vehicle in violation of the above re-
quirements can cause severe transmission and/or
transfer case damage. Damage from improper tow-
ing is not covered under the New Vehicle Limited
Warranty.
• Do not use a bumper-mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
5 STARTING AND OPERATING 533

Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for
recreational towing.
WARNING!You or others could be injured 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-
shafts from the powertrain and will allow the vehicle
to move, even if the transmission is in PARK. 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. Turn OFF the engine.
3. Press and hold the brake pedal.
4. Shift the automatic transmission into NEUTRAL or
depress the clutch pedal on a manual transmission.
5. Shift the transfer case lever into NEUTRAL (N).
6. Start the engine.534 STARTING AND OPERATING

7. Shift the transmission into REVERSE.
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 OFF the engine.
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.
5 STARTING AND OPERATING 535

Shifting Out of NEUTRAL (N)

3. Turn the ignition switch to the LOCK/OFF 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.
7. Shift the transfer case lever to the desired position. NOTE: When shifting out of transfer case NEUTRAL
(N), turning the engine OFF may be required 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.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel below the climate controls.
Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists. When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into
NEUTRAL, but do not increase engine idle speed.538 WHAT TO DO IN EMERGENCIES
