2012 JEEP LIBERTY tow

NOTE:Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options, or authorized dealer-installed
options, must be considered as part of the total load on
your vehicle. Refer to the “Tire and Loading Information”
placard for the maximum combined weight of occupants
and cargo for your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drive-
train components, the following guidelines are recom-
mended:
CAUTION!
•Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine,
axle or other parts could be damaged.
(Continued)
CAUTION! (Continued)
•Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full throttle.
This helps the engine and other parts of the
vehicle wear in at the heavier loads.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible: (Continued)
418 STARTING AND OPERATING

WARNING! (Continued)
•Make certain that the load is secured in the trailer
and that is will not shift during travel. When
trailering cargo that is not fully secured, dynamic
load shifts can occur that may be difficult for the
driver to control. You could lose control of your
vehicle and have a collision.
•When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance, or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and
allow enough slack for turning corners.(Continued)
WARNING! (Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission
in PARK. Always, block orchockthe trailer
wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized (This requirement may limit the ability to
always achieve the 10% to 15% range of tongue
weight as a percentage of total trailer weight).

Towing Requirements – Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for information on tire pressures and for proper
tire inflation procedures.
Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for informa-
tion on tread wear indicators and for the proper
inspection procedure.
When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for information on replacement tires and for the proper tire replace-
ment procedures. Replacing tires with a higher load
carrying capacity will not increase the vehicle’s GVWR
and GAWR limits.
Towing Requirements – Trailer Brakes

Do
not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
420 STARTING AND OPERATING

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes, and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.(Continued)
WARNING! (Continued)
•Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.5
STARTING AND OPERATING 421

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing the trailer in an area located away from
heavy traffic.
Automatic Transmission
The “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range,
activate the TOW/HAUL feature. Refer to “Automatic
Transmission” in “Starting and Operating” for further
information.
NOTE:Using the TOW/HAUL feature while operating
the vehicle under heavy operating conditions will im-
prove performance and extend transmission life by re-
ducing excessive shifting and heat build up. 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 automatic
transmission fluid and filter according to the interval specified for “police, taxi, fleet, or frequent trailer tow-
ing.” Refer to “Maintenance Schedule” for the proper
maintenance intervals.
TOW/HAUL
To reduce potential for automatic transmission overheat-
ing, press the TOW/HAUL button when driving in hilly
areas or select the
2range on more severe grades. Refer
to “Automatic Transmission” in “Starting and Operat-
ing” for further information.
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.

Recreational Towing — Two-Wheel Drive Models
Recreational towing is allowed ONLY if the rear wheels
areOFF the ground. This may be accomplished using a
tow dolly or vehicle trailer. If using a tow dolly, follow
this procedure:
1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly set the parking brake. Place the transmission in
PARK.
4. Properly secure the rear wheels to the dolly, following
the dolly manufacturer’s instructions.
5. Remove the ignition key.
6. Install a suitable clamping device, designed for tow-
ing, to secure the front wheels in the straight position. Flat towing (with all four wheels on the ground) is
allowed ONLY if the driveshaft is removed.
Towing
with the rear wheels on the ground while the driveshaft
is connected will result in severe transmission damage.
WARNING!
If the driveshaft is removed, the vehicle can roll even
if the transmission is in PARK, which could cause
serious injury or death.
The parking brake mustbe firmly engaged and the
wheels chocked during driveshaft removal and installa-
tion. The parking brake must remainengaged unless the
vehicle is securely and properly connected to the tow
vehicle, or the driveshaft is completely reinstalled. See
your authorized dealer for proper driveshaft removal
and reinstallation procedures, including flange
orientation/alignment, use of thread-locking compound,
proper bolt torque specifications, etc.

STARTING AND OPERATING 425

CAUTION!
Towing with the rear wheels on the ground (while
the driveshaft is connected) will cause severe trans-
mission damage. Damage from improper towing is
not covered under the New Vehicle Limited War-
ranty.
Recreational Towing — Four-Wheel Drive Models
The transfer case must be shifted into NEUTRAL (N) and
the transmission must be placed in PARK for recreational
towing. The NEUTRAL (N) selection button is adjacent to
the transfer case selector switch. Shifts into and out of
transfer case NEUTRAL (N) can take place with the
selector switch in any mode position.
CAUTION!
•Front or rear wheel lifts should not be used.
Internal damage to the transmission or transfer
case will occur if a front or rear wheel lift is used
when recreational towing.
•Tow only in a forward direction. Towing this
vehicle backwards can cause severe damage to the
transfer case.
•The transmission must be placed in PARK 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 NEU-
TRAL (N). Otherwise, internal damage will result.
•Failure to follow these procedures can cause se-
vere transmission and/or transfer case damage.(Continued)
