2004 JEEP LIBERTY tires

Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should feel the air
directed against the windshield.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil or other fluid leaks. Also, if gasoline fumes
are detected, the cause should be located and corrected
immediately.

²SPARE SWAP DETECTED
Tire Pressure Monitor System
The Tire Pressure Monitor (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 over-
head console.
The tire pressure is shown in the Electronic Vehicle
Information Center (EVIC) display. The TPM system
remains active even if it is not displayed in the EVIC.
CAUTION!
The TPM system is designed to monitor your tire
pressure and will not function as a tire pressure
gauge while adjusting the pressure in your tires.
There will be a delay between the instant you adjust
the air pressure in a tire and when the system
updates the display.
NOTE:The TPM system can inform you about a low or
high tire pressure condition, but it does not replace
normal tire maintenance.
The TPM system is not intended to provide you with
notification of rapid pressure loss.
1. If any tire pressure has exceeded the low or high
pressure (refer to STARTING AND OPERATING Ð
TIRES AND WHEELS), the TPM system will display a
message in the EVIC and sound a chime. It will then go

into the tire pressure display screen and flash the pres-
sure value of the tire that is low or high. This will be
displayed for the rest of the ignition cycle, or until the
C/T, MENU, STEP, or RESET button is pressed.
NOTE:This display will return 60 seconds after the
C/T, MENU, STEP, or RESET button is pressed. If a tire is
low or high, you should correct your tire inflation
pressure as soon as possible and inspect all of your tires.
Refer to STARTING AND OPERATING Ð TIRES AND
WHEELS for more details.
Once the low or high tire pressure message has occurred,
it will continue to blink until the tire pressure is cor-
rected.
2. If the spare tire pressure has exceeded the low or high
pressure allowed, the TPM system will display a message
in the EVIC for 60 seconds and sound a chime each
ignition cycle.NOTE:This message will return every ignition cycle,
until the tire pressures are corrected.
3. When the vehicle is moving and the EVIC cannot
receive a valid sensor signal from the tire pressure
sensors, the TIRE PRESSURE UNAVAILABLE message
will be displayed for 3 seconds along with a chime. The
display will then shift to the individual tire pressure
display screen and display dashes for the tire or tires that
are affected. If the TIRE PRESSURE UNAVAILABLE
message has been displayed, and valid sensor signals are
received, the EVIC will display the TIRE PRESSURE
NOW AVAILABLE message for 3 seconds along with a
chime. This is meant to inform you when the TPM system
has returned to it's normal operation. This will occur
when valid tire pressure sensor messages have been
received from all 4 road tires. TPM system function may
be temporarily unavailable due to external electromag-
netic interference, such as electronic devices or nearby
radio or TV towers.

4. In addition to monitoring the vehicle tires, the TPM
system monitors faults within the system. When any
fault has been set, the TPM system will display TIRE
SENSOR BAD/MISSING. Be sure to inspect your tires for
proper inflation pressure. After you determine that your
tires are properly inflated, see your authorized dealer for
service to diagnose the problem with the TPM system.
5. If a road tire is replaced by the spare, the TPM system
will automatically detect that the tires have been
switched (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).
General Information
This device complies with FCC rules part 15 and with
RSS-210 of Industry Canada. Operation is subject to the
following conditions:
1. This device may not cause harmful interference2. This device must accept any interference that may be
received, including interference that may cause undes-
ired operation
Changes or modifications not expressly approved by the
party responsible for compliance could void the user's
authority to operate the device.

Customer Programmable Features
Press the MENU button until one of the display choices
following appears:
Language?
When in this display you may select one of five lan-
guages for all display nomenclature, including the trip
computer functions. Press the STEP button while in this
display to select English, Francais, Deutsch, Italiana, or
Espanol. As you continue the displayed information will
be shown in the selected language.

NOTE:The tire pressure sensors must be retrained after
rotating the tires or replacing one or more sensors. If a
wheel rotation is not followed by the retrain procedure,
the system will not properly inform you of the correct
vehicle location for a low or high pressure tire.
The following describes how to use this feature:
1. Locate the training magnet in the glove compartment
(shaped like a doughnut).
2. Press the MENU button until RETRAIN TIRE SEN-
SORS is displayed.
3. Press the STEP button to select YES to retrain TPM
sensor.
4. Press the MENU button to enter selection.
5. Display will read TRAIN LEFT FRONT TIRE.NOTE:There is a 60 second timer for training the first
tire and a 30 second timer between training the remain-
ing tires. If either of these timers expire, the EVIC will
abort the training procedure.
6. Starting at the left front tire, place the training magnet
over the valve stem until the horn chirps (This takes
approximately 5 seconds).

INSTRUMENT CLUSTER DESCRIPTION
1. Tachometer
Indicates the permissible engine revolutions-per-minute
for each gear range. Before reaching the red area, ease up
on the accelerator to prevent engine damage.
2. Turn Signal Indicator Light
The arrows will flash in unison with the exterior
turn signals, when using the multi-function control
lever. A chime will sound if the turn signals are left on
continuously for 2 miles (3 km) until they are deacti-
vated.
3. High Beam Indicator Light
This light shows that the headlights are on high
beam. Pull the multi-function control lever to-
wards the steering wheel to switch the headlights from
high to low beam.4. Speedometer
Indicates vehicle speed.
5. Tire Pressure Monitor Warning Light Ð If Equipped
This light will turn on when there is a low tire
pressure condition. The light will also turn on
if a problem exist with any tire sensor. The light
will remain on until the tire pressure is prop-
erly set or the problem with the sensor is corrected.
This light will turn on momentarily as a bulb check when
the engine is started.
When the ªTire Pressure Monitor Warning Lightº is lit,
one or more of your tires is significantly under-inflated.
You should stop and check your tires as soon as possible,
and inflate them to the proper pressure as indicated on
the vehicle's tire information placard. Driving on a
significantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect

208 STARTING AND OPERATING

CAUTION!
²Do not attempt to make a shift while only the
front or rear wheels are spinning. The Command-
Trac transfer case is not equipped with a synchro-
nizer and therefore the front and rear driveshaft
speeds must be equal for the shift to take place.
Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.
²When operating your vehicle in 4L, the engine
speed is approximately three times that of the 2H
or 4H positions at a given road speed. Take care
not to overspeed the engine and do not exceed 25
mph (40 km/h).
Proper operation of 4-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference will adversely affect shifting and can
cause damage to the transfer case.
