2005 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.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

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.
After completing three 360 degree turns in an area free
from large metal or metallic objects, the CAL symbol will
turn off and the compass will function normally.
Manual Compass Calibration
If the compass appears erratic and the CAL symbol does
not appear, you must manually put the compass into the
“Calibration” mode.
To Put Into a Calibration Mode
Turn on the ignition and set the display to “Compass/
Temperature.” Press and hold the RESET button (more
than 10 seconds) to change the display between VARI-
ANCE (compass variance) and CAL (compass calibra-
tion) modes. When the CAL symbol is displayed com-
plete three 360 degree turns in an area free from large
metal objects or power lines. The CAL symbol will turn
off and the compass will function normally.

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 — 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 “Tire Pressure Monitor Warning Light” 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
168 UNDERSTANDING YOUR INSTRUMENT PANEL

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. (See page 268 for more
information.)
6. 4LO Mode Indicator Light — 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. (See page 236 for more infor-
mation.)
7. Fog Light Indicator Light — 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 position
before 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 “Malfunction Indicator
Light” may flash to alert of serious conditions that could
lead to immediate loss of power or severe catalytic

ANTI-LOCK BRAKE SYSTEM — IF EQUIPPED
The Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lock-up and help avoid skidding on slippery surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
WARNING!
Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The Anti-Lock Brake System conducts a low speed self-test
at about 12 mph (20 km/h). If for any reason, your foot is
on the brake when the vehicle reaches 12 mph (20 km/h),
this check will be delayed until 25 mph (40 km/h).
The Anti-Lock Brake System pump motor runs during
the self-test and during an ABS stop to provide the
regulated hydraulic pressure. The motor pump makes a
low humming noise during operation, this is normal.
During off-road use, loss of traction can temporarily
defeat the system and cause the warning light to illumi-
nate. Turn the ignition OFF and ON again to restore
Anti-Lock Brake System function.

TIRE SAFETY INFORMATION
Tire Markings
NOTE:
•P(Passenger)-Metric tire sizing is based on U.S. design
standards. P-Metric tires have the letter “P” molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.
•European 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 letterPis absent from this tire
size designation. Example: 215/65R15 96H
•LT(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 “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary Spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
•High 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.
