2004 JEEP LIBERTY Section 2

²European Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter9P9is absent from this tire
size designation. Example: 215/65R15 96H
²LT(Light Truck)-Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters ªLTº that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
²Temporary Spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter ªTº
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
²High Flotation tire sizing is based on U.S. design
standards and begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

4) the cold tire inflation pressures for the front, rear
and spare tires.
Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire's load carrying capacity if you
adhere to the loading conditions, tire size and cold tire
inflation pressures specified on the Tire and Loading
Information placard and the Vehicle Loading section of
this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR's) for the front and rear
axles must not be exceeded. For further information on
GAWR's, vehicle loading and trailer towing, see the
Vehicle Loading section of this manual.To determine the maximum loading conditions of your
vehicle, locate the statement ªThe combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs.º on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement ªThe combined weight of occu-
pants and cargo should never exceed XXX poundsº on
your vehicle's placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.

Tread Wear Indicators
These indicators are narrow strips 1/16 inch (1.6 mm)
thick and are found in the tread pattern grooves.
When the tread pattern is worn down to these treadwear
indicators, the tires should be replaced.
Overloading your vehicle, long trips in very hot weather,
and driving on bad roads may result in greater wear.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct inflation pressure. The manufacture
strongly recommends that you use tires equivalent to the
originals in quality and performance when replacement
is needed (see section on tread wear indicators). Failure
to use equivalent replacement tires may adversely affect
the safety, handling, ride and fuel economy of your
vehicle. We recommend that you contact your original
equipment tire dealer on any questions you may have on
tire specifications or capability.
252 STARTING AND OPERATING

Tires may also cause the vehicle to pull left or right.
Alignment will not correct this problem. See your dealer
for proper diagnosis of the problem.
Improper alignment will not normally cause vehicle
vibration, which may be a result of tire and wheel
out-of-balance. Proper balancing will reduce vibration
and avoid tire cupping and spotty wear.
TIRE PRESSURE MONITOR SYSTEM Ð IF
EQUIPPED
The Tire Pressure Monitor System (TPM) monitors the
pressure in all 4 road tires and the full size spare. The
TPM system uses wireless technology to monitor tire
pressure levels. Sensors, mounted to each wheel as part
of the valve stem, transmit tire pressure readings to a
receiver located in the overhead console. The tire pres-
sure status is shown in the Electronic Vehicle Information
Center (EVIC) display. Refer to ªOverhead Consoleº inSection 3 for more information. The TPM system func-
tions even when the EVIC is not set on the tire pressure
display screen.
The TPM system informs you of a low or high tire
pressure condition. If this occurs, correct your tire infla-
tion pressure as soon as possible, and inspect all of your
tires. Be sure to use a high quality gauge when adjusting
pressure. The TPM system is designed to monitor your
tire pressure but will not function as a tire pressure
gauge. There will be a delay between the instant you
adjust the air pressure in a tire and when the system
updates the display. The TPM system is not intended to
provide you with notification of rapid air loss.
254 STARTING AND OPERATING

Tire Pressure Monitor System Tire/Wheel
Rotation and Sensor Replacement Ð If Equipped
With the TPM System, if a road tire and wheel is replaced
by the spare, the TPM system will detect the swap
automatically (after the ignition has been cycled) and
display SPARE SWAP DETECTED along with a chime.
This could take up to 10 minutes with vehicle speed
above 25 mph (40 km/h).
The tire pressure sensorsmustbe retrained following a
wheel rotation or sensor replacement. Refer to ªEVIC Ð
Retrain Tire Sensorsº in Section 3 for more information. It
is necessary to program the EVIC with the new sensor(s)
or the new position of each sensor as it is rotated to a
different corner of the vehicle.
If a wheel rotation is not followed by the retrain proce-
dure, the system will not properly inform you of the
correct vehicle location of a low or high tire pressure.
Tire Pressure Monitor System/4±LO Mode Ð If
Equipped
When the 4±LO mode is selected, the chime will not
sound until either: the vehicle speed is greater or equal to
25 mph (40 km/h) or the vehicle is taken out of the 4±LO
mode.
The low tire pressure warning messages (on the EVIC)
and the ªTire Pressure Monitor Warning Lightº will
continue to be displayed until the tire pressure has been
increased to the proper operating pressure.
General Information
This device complies with part 15 of the FCC rules and
RSS 210 of Industry Canada. Operation is subject to the
following conditions:
²This device may not cause harmful interference.
256 STARTING AND OPERATING

Tire chains that are recommended for this vehicle are
listed below:
²MopartP/N 82206828 with P235/70R16 and P235/
65R17 tires.
²MopartP/N 82207074 with P215/75R16 tires.
NOTE:In order to avoid damage to tires, chains, and
your vehicle do not drive for a prolonged period of time
on dry pavement. Observe the tire chain manufacturer's
instructions on method of installation, operating speed,
and conditions for usage.
Always use the lower suggested operating speed if both
the chain manufacturer and vehicle manufacturer sug-
gest a maximum speed. This notice applies to all chain
traction devices, including link and cable (radial) chains.
TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates, and develop irregular wear patterns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off Road
type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.
Follow the recommended tire rotation frequency for your
type of driving found in the ªMaintenance Schedulesº
Section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
258 STARTING AND OPERATING

CAUTION!
If the ªMalfunction Indicator Lightº is flashing,
immediate service is required. See ªOnboard Diag-
nostic Systemº in Section 7 of this manual.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions.
FUEL TANK FILLER CAP (GAS CAP)
WARNING!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.
The gas cap is located behind the fuel filler door, on the
left side of the vehicle. If the gas cap is lost or damaged,
be sure the replacement cap has been designed for use
with this vehicle.
When tightening the gas cap, tighten until 2 or 3 clicks
are heard to insure that the cap is properly seated.
NOTE:A loose gas cap may cause the ªMalfunction
Indicator Lightº to illuminate.
