tire type JEEP LIBERTY 2010 KK / 2.G Owners Manual

The Advanced Front Airbags have a multistage inflator
design. This allows the airbag to have different rates of
inflation that are based on the severity and type of
collision.This vehicle may also be equipped with Supplemental
Side Airbag Inflatable Curtains (SABIC) that run the
entire length of the headliner to protect the driver, front,
and rear passengers sitting next to a window.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 57

maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or moretires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.

position locks the front driveshaft and rear driveshaft
together and forces the front and rear wheels to rotate at
the same speed.
Use the transfer case NEUTRAL position for recreational
towing only. Refer to “Recreational Towing” in this
section for specific procedures on shifting into and out of
NEUTRAL.
CAUTION!
•Do not attempt to make a shift while only the front
wheels or rear wheels are spinning. The MP1522
Command-Tractransfer case is not equipped
with a synchronizer and therefore the speed of the
front driveshaft and rear driveshaft must be equal
for the shift to take place. Shifting while only the
front wheels or rear wheels are spinning can cause
damage to the transfer case.

CAUTION! (Continued)
•The 4WD LOCK position and 4WD LOW position
are intended for loose or slippery road surfaces
only. Driving in these positions on dry hard-
surfaced roads may cause increased tire wear and
damage to the driveline components.
•When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD LOCK position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
•Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case.
310 STARTING AND OPERATING

This transfer case is intended to be driven in either the
two-wheel drive position (2WD) or the four-wheel drive
Auto position (4WD AUTO) for normal street and high-
way conditions such as dry hard-surfaced roads.
For added capability when traversing steep grades,
rough terrain, or extremely poor traction surfaces, select
the transfer case 4WD LOW position. This position locks
the front driveshaft and rear driveshaft together and
forces the front and rear wheels to rotate at the same
speed while multiplying engine torque.
Use the transfer case NEUTRAL position for recreational
towing only. Refer to “Recreational Towing” in this
section for specific procedures on shifting into and out of
NEUTRAL.CAUTION!
•The 4WD LOW position is intended for loose or
slippery road surfaces only. Driving in this posi-
tion on dry hard-surfaced roads may cause in-
creased tire wear and damage to the driveline
components.
•When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD AUTO position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
•Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case.
316 STARTING AND OPERATING

When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
ANTI-LOCK BRAKE SYSTEM
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer 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 ABS conducts a low-speed self-test at about 12 mph
(20 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.
The ABS pump motor runs during the self-test at 12 mph
(20 km/h) and during an ABS stop. The pump motor
makes a low humming noise during operation, which is
normal.

STARTING AND OPERATING 329

WARNING! (Continued)
•Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
•Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-inflation also increases
tire rolling resistance and results in higher fuel
consumption.
Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride. Both under-inflation and over-inflation affect thestability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the steering.
Unequal tire pressures can cause erratic and unpredict-
able steering response.
Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side “B” Pillar.
The pressure should be checked and adjusted, as well as
inspected for signs of tire wear or visible damage, at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under-inflated.5
STARTING AND OPERATING 353

Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle at or above
maximum load is dangerous. The added strain on
your tires could cause them to fail. You could have a
serious accident. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial-Ply Tires
WARNING!
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.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized dealer for radial tire repairs.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.

STARTING AND OPERATING 355

CAUTION!
Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type and circumference
on each wheel. Any difference in tire size can cause
damage to the transfer case. Tire rotation schedule
should be followed to balance tire wear.
Life Of Tire
The service life of a tire is dependent upon various
factors including but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
358 STARTING AND OPERATING

WARNING! (Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE CHAINS
Use only compact chains, or other traction aids that meet
SAE type “Class S” specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer. In addition, only install tire chains on
P225/75R16 or smaller tires.
CAUTION!
To avoid damage to your vehicle, tires, or chains,
observe the following precautions:
•Do not use tire chains on vehicles equipped with
tires other than P225/75R16 or smaller tires. There
may not be adequate clearance for the chains and
you are risking structural or body damage to your
vehicle.
•Because of limited chain clearance between tires
and other suspension components, it is important
that only chains in good condition are used. Bro-
ken chains can cause serious vehicle damage. Stop
the vehicle immediately if noise occurs that could
suggest chain breakage. Remove the damaged
parts of the chain before further use.(Continued)
360 STARTING AND OPERATING

The suggested rotation method is the “forward-cross”
shown in the following diagram.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off Roadtype tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.
CAUTION!
Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type and circumference
on each wheel. Any difference in tire size can cause
damage to the transfer case. Tire rotation schedule
should be followed to balance tire wear.
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals. Remember, more frequent
rotation is permissible if desired. Also, correct for any-
thing causing rapid or unusual wear prior to performing
the tire rotation.
