2004 JEEP LIBERTY spare wheel

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 HIGH PRESSURE
²TIRE PRESSURE UNAVAILABLE
²TIRE PRESSURE NOW AVAILABLE
²TIRE SENSOR BAD/MISSING
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
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.

the vehicle's handling and stopping ability. Each tire,
including the spare, should be checked monthly when
cold and set to the recommended inflation pressure as
specified on the vehicle placard.
6. 4LO Mode Indicator Light Ð If Equipped
This light alerts the driver that the vehicle is in
the 4 LO four±wheel drive mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed.
7. Fog Light Indicator Light Ð If Equipped
This light shows when the front fog lights are on.
8. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD II which monitors engine and auto-
matic transmission control systems. This light
will illuminate when the ignition is in the ON positionbefore engine start. If the bulb does not come on when
turning the ignition key from OFF to ON, have the
condition checked promptly.
Certain conditions such has a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving cycles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the ªMalfunction Indicator
Lightº may flash to alert of serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
9. Anti-Lock Warning Light (ABS) Ð If Equipped
This light monitors the Anti-Lock Brake System
(ABS) described elsewhere in this manual. This

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.
