Tire JEEP LIBERTY 2003 Owners Manual

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

Even if the display still reads a few degrees above
32ÉF (0ÉC), the road surface may be icy, particularly
in woods or on bridges. Drive carefully under such
conditions to prevent an accident and possible per-
sonal injury or property damage.

Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.

EXAMPLE:
Size Designation:
P= Passenger car tire size based on U.S. design standards

STARTING AND OPERATING 241

Overloading of your tire is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
Improperly inflated tires are dangerous and can
cause accidents.
²Under inflation increases tire flexing and can
result in tire failure.
²Over inflation reduces a tire's ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
²Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
²Overinflated or under inflated tires can affect
vehicle handling and can fail suddenly, resulting in
loss of vehicle control.
Always drive with each tire inflated to the recom-
mended pressure.

High speed driving with your vehicle under load is
dangerous. The added strain on your tires could
cause them to fail. You could have a serious accident.
Don't drive a vehicle loaded to maximum capacity at
continuous speeds above 75 mph (120 km/h).

Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial tires in sets of four. Never combine
them with other types of tires.
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure
someone. Do not spin your vehicle's wheels faster
than 35 mph (55 km/h) when you are stuck. And
don't let anyone near a spinning wheel, no matter
what the speed.

CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings. Check with your dealer before replacing tires
with a different size.

High Pressure Threshold 44 psi (303 kPa )
Placard Pressure (Cold) 33 psi (227 kPa)
Low Pressure Threshold 25 psi (172 kPa)
NOTE: A TPM system does not replace normal tire
maintenance.
CAUTION!

To avoid damage to your vehicle or tires, observe the following
precautions:
²Because of restricted chain clearance between tires and other
suspension components, it is important that only chains in
good condition are used. Broken chains can cause serious
damage. Stop the vehicle immediately if noise occurs that could
indicate chain breakage. Remove the damaged parts of the
chain before further use.
²Install chains on the rear wheels as tightly as possible and then
retighten after driving about1¤2mile (0.8 km).
²Do not exceed 30 mph (48 km/h).
²Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
²Do not drive for prolonged period on dry pavement.
²Observe the tire chain manufacturer's instructions on the
method of installation, operating speed, and conditions for use.
Always use the lower suggested operating speed of the chain
manufacturer if different than the speed recommended by the
manufacture.
