2004 JEEP LIBERTY tire pressure

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.

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
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 113

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

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).

7. Repeat step 6 working clockwise around the vehicle
(Left Front, Right Front, Right Rear, Left Rear, Spare) until
all five TPM sensor positions are trained.
8. Return magnet to storage location.If the display reads TRAINING COMPLETE, pressing
either the STEP, C/T, RESET, or MENU buttons will exit
the training mode.
If the display reads TRAINING ABORTED, move the
vehicle ahead at least 1 foot and complete steps 1±8
again.

Mini-Trip Computer
This feature, located in the overhead console, displays
information on outside temperature, compass direction,
and trip information.
Reset Button
Use this button to reset the Average Economy, Trip Miles,
and Time Elapsed displays to zero. This will occur only if

Average Miles/GAL
Shows the average fuel economy in miles per gallon
(MPG), or liters per 100 km (L/100 km) since the last
reset.
Miles To Empty
Shows the estimated distance that can be traveled before
the fuel gauge shows E (Empty). The distance is calcu-
lated by multiplying the amount of fuel remaining by the
projected fuel economy. The distance predicted will
change every few seconds to a higher or lower number as
these factors change. This display cannot be reset.
Trip Miles
Shows the distance travelled since the last reset.
Time Elapsed
Shows the accumulated ignition ON time since the last
reset.Miles To Service
Shows the amount of miles remaining until service is
required (owner selected).
Tire PSI
Shows the pressure and location of each tire, except for
the spare tire. The tire location will blink when under
pressure.
Blank Screen
Shows a blank screen. Pressing the C/T button returns to
the Compass and Temperature display. Pressing the STEP
button returns you to the Average Miles per Gallon
display.
Automatic Compass Calibration
This compass is self-calibrating which eliminates the
need to manually set the compass. When the vehicle is
new, the compass may appear erratic and the CAL
symbol will be displayed.
