JEEP PATRIOT 2007 1.G Owners Manual

Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare.
Do not install more than one compact spare tire/wheel
on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with the
compact spare installed. Damage to the vehicle may
result.
Limited Use Spare Ð If Equipped
The limited use spare tire is for temporary emergency use
on your vehicle. This tire is identified by a limited use
spare tire warning label located on the limited use spare
tire and wheel assembly. This tire may look like theoriginal equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited use spare
tire affects vehicle handling. Since it is not the same tire,
replace (or repair) the original tire and reinstall on the
vehicle at the first opportunity.
WARNING!
The limited use spare tires are for emergency use
only. Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive more
than 60 mph (100 km/h). Keep inflated to the cold tire
inflation pressure listed on either your tire placard or
limited use spare tire and wheel assembly. Replace
(or repair) the original tire at the first opportunity
and reinstall it on your vehicle. Failure to do so could
result in loss of vehicle control.
290 STARTING AND OPERATING

Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 30 mph (48 km/h) or
for more than 30 seconds.
Refer to the paragraph on ªFreeing A Stuck Vehicleº in
Section 6 of this manual.
WARNING!
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 some-
one. Do not spin your vehicle's wheels faster than 30
mph (48 km/h) or for more than 30 seconds continu-
ously when you are stuck, and don't let anyone near
a spinning wheel, no matter what the speed.
Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
STARTING AND OPERATING 291

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.
Many states have laws requiring tire replacement at this
point.
Life of Tire
The service life of a tire is dependent upon varying
factors including but not limited to:
²Driving style
²Tire pressure
²Distance driven
WARNING!
Tires and 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.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (refer to the paragraph on
292 STARTING AND OPERATING

ªTread Wear Indicatorsº). Refer to the ªTire and Loading
Informationº placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.WARNING!
²Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
You could lose control and have an accident resulting
in serious injury or death. Use only the tire and wheel
sizes with load ratings approved for your vehicle.
²Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
²Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.
STARTING AND OPERATING 293

CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer
readings.
Alignment And Balance
Poor suspension alignment may result in:
²Fast tire wear.
²Uneven tire wear, such as feathering and one-sided
wear.
²Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.Improper alignment will not cause vehicle vibration.
Vibration 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 MONITORING SYSTEM (TPMS)
Ð IF EQUIPPED
Base Tire Pressure Monitoring System (TPMS)
Operation ± If Equipped
This is the Tire Pressure Monitoring System warn-
ing indicator located in the instrument cluster.
²The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
²The tire pressure will vary with temperature by about
1 psi (6.9 kPa) for every 12 ÉF (6.5 ÉC). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
294 STARTING AND OPERATING

based on cold inflation tire pressure. This is defined as
the tire pressure after a vehicle has not been driven for
more than 3 hours - and in outside ambient tempera-
ture. Refer to the ªTires ± General Informationº in this
section for information on how to properly inflate the
vehicle's tires. The tire pressure will also increase as
the vehicle is driven - this is normal and there should
be no adjustment for this increased pressure.
²The TPM System will warn the driver of a low tire
pressure if the tire pressure falls below the low pres-
sure warning threshold for any reason, including low
temperature effects.
²The TPM System will continue to warn the driver of
low tire pressure as long as the condition exists, and
will not turn off until the tire pressure is at or above
recommended cold placard pressure. Once the low tire
pressure warning has been illuminated, the tire pres-
sure must be increased to the recommended coldplacard pressure in order for the TPM warning lamp to
be turned off. The system will automatically update
and the TPM warning lamp will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 10 minutes above 15
mph (25 km/h) to receive this information.
For example, your vehicle may have a recommended
cold (parked for more than 3 hours) placard of 35 ÉF (241
kPa). If the ambient temperature is 68 ÉF (20 ÉC) and the
measured tire pressure is 30 psi (207 kPa), a temperature
drop to 20 ÉF (-7 ÉC) will decrease the tire pressure to
approximately 26 psi (179 kPa). This tire pressure is
sufficiently low enough to turn ON the ªTire Pressure
Monitoring Lightº. Driving the vehicle may cause the tire
pressure to rise to approximately 30 psi (207 kPa), but the
ªTire Pressure Monitoring Lightº will still be ON. In this
situation, the ªTire Pressure Monitoring Lightº will turn
OFF only after the tires have been inflated to the vehicle's
recommended cold placard pressure value.

Premium System ± If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²3 Trigger Modules (mounted in three of the four wheel
wells)
²Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
²Yellow Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Lamp will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more of the four active road tire
pressures are low. The audible chime will sound once
every ignition cycle for each condition that it detects. In
addition, the Electronic Vehicle Information Center
(EVIC) will display a graphic of the pressure value(s)
with the low tire(s) flashing.
296 STARTING AND OPERATING

Display Settings
²Your system can be set to display pressure units in PSI,
kPa, or BAR.NOTE:These display settings may not be available due
to Regulatory Authorities. In this case, the display will
only show approved units.
NOTE:A low spare tire will not cause the Tire Pressure
Monitoring Telltale Lamp to illuminate or the chime to
sound.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle's recommended cold placard pres-
sure value. The system will automatically update, the
graphic display of the pressure value(s) will stop flash-
ing, and the Tire Pressure Monitoring Lamp will extin-
guish once the updated tire pressure(s) have been re-
ceived. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation.
Low Tire Pressure Display
STARTING AND OPERATING 297

Check TPM System Message
The Tire Pressure Monitoring Telltale Light will flash on
and off for 60 seconds, and an audible chime will sound
when a system fault is detected. The flash cycle will
repeat every ten minutes, without an audible chime, until
the fault condition no longer exists.
The EVIC will display the ªCHECK TPM SYSTEMº
message for 3 seconds. This text message is then followed
by a graphic, with ª- -ª displayed for the pressure value
indicating which of the Tire Pressure Monitoring Sen-
sor(s) is not being received.
If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, and the9CHECK TPM SYS-
TEM9text message will no longer display.

298 STARTING AND OPERATING

Display Settings
²Your system can be set to display pressure units in PSI,
kPa, or BAR.
NOTE:These display settings may not be available due
to Regulatory Authorities. In this case, the display will
only show approved units.
NOTE:If your vehicle is equipped with a compact spare
wheel and tire assembly that does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the Tire Pressure Monitor System (TPMS). In the event
that the compact spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the ªTire Pressure Monitoring Lampº to be ON, a
chime to sound, and the Electronic Vehicle Information
Center (EVIC) will still show the low tire pressure value
flashing on the graphic display. However, driving the
vehicle for up to 10 minutes above 15 mph (25 km/h) will
display a ªCHECK TPM SYSTEMº text message on theEVIC. This text message will then be followed by a
graphic, with ª- -ª in place of the flashing low pressure
value. For every subsequent key cycle, the ªTire Pressure
Monitoring Lampº will be ON, a chime will sound, a
ªCHECK TPM SYSTEMº text message will be display in
the EVIC, and the graphic display will have ª- -ª in place
of the pressure value of the spare tire location. Once the
original road tire has been properly repaired, and put
back onto the vehicle in place of the compact spare tire.
The TPMS will update the graphic display on the EVIC
with a new tire pressure value instead of ª- -ª, and the
ªTire Pressure Monitoring Lampº will be OFF as long as
none of the road tire(s) are below the low pressure
warning threshold. The vehicle may need to be driven for
up to 10 minutes above 15 mph (25 km/h) to receive this
information.
