2008 JEEP COMPASS flat tire

CAUTION!
²The 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
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
²After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.NOTE:
²The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
²Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's handling and
stopping ability.
²The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver 's responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
light.
268 STARTING AND OPERATING

²Seasonal temperature changes will affect tire pressure,
and the TPM system will monitor the actual tire
pressure in the tire.
Base System ± If Equipped
This is the Tire Pressure Monitoring System warn-
ing indicator located in the instrument cluster.
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 the tires on your vehicle regularly
and to maintain the proper pressure.The TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²Tire Pressure Monitoring Telltale Light
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. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire
on your vehicle, and inflate each tire to the vehicle's
recommended cold placard pressure value. The system
will automatically update and the Tire Pressure Monitor-
ing 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 kph) to receive
this information.

addition, the Electronic Vehicle Information Center
(EVIC) will display a graphic of the pressure value(s)
with the low tire(s) flashing.
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 graphicdisplay 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 kph) to receive this informa-
tion.
Check TPM System Message
The Tire Pressure Monitoring Telltale Lamp will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a ªCHECK TPM SYS-
TEMº message for 3 seconds. This text message is then
followed by a graphic display, with ª- -ª in place of the
pressure value(s) indicating which Tire Pressure Moni-
toring Sensor(s) is not being received.

4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
Towing Requirements Ð Tires
þ
Do not attempt to tow a trailer while using a compact
spare tire.
þProper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to the
Tires±General Information section of this manual on
Tire Pressures for proper tire inflation procedures.
þAlso, check the trailer tires for proper tire inflation
pressures before trailer usage.
þCheck for signs of tire wear or visible tire damage
before towing a trailer. Refer to the Tires±General
Information section of this manual on Tread Wear
Indicators for the proper inspection procedure.
þWhen replacing tires refer to the Tires±General Infor-
mation section of this manual on Replacement Tires for
proper tire replacement procedures. Replacing tires
with a higher load carrying capacity will not increase
the vehicle's GVWR and GAWR limits.
Towing Requirements Ð Trailer Brakes
þ
Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
þAn electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.

7. Lower the vehicle by turning the jack screw to the left.
8. Finish tightening the nuts. Push down on the wrench
while tightening the wheel nuts. Alternate nuts until each
nut has been tightened twice. Correct wheel nut torque is
100 ft. lbs (135 N´m). If you doubt that you have
tightened the nuts correctly, have them checked with a
torque wrench by your dealer or at a service station.
9. Remove the wheel blocks and lower the jack until it is
free. Reassemble the lug wrench to the jack assembly and
stow it in the spare tire area. Secure the assembly using
the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.10. Place the deflated (flat) tire in the cargo area,have the
tire repaired or replaced as soon as possible.
WARNING!
A loose tire thrown forward in a collision or hard
stop could injure the occupants in the vehicle. Have
the deflated (flat) tire repaired or replaced
immediately.
11. Check the tire pressure as soon as possible. Correct
pressure as required.

and First gear. Usually the least accelerator pedal pres-
sure to maintain the rocking motion without spinning the
wheels is most effective.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause axle, tire
damage or failure. A tire could explode and injure
someone. Do not spin your vehicle's wheels faster
than 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping when you are stuck.
And don't let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transaxle overheating and failure. It can
also damage the tires. Do not spin the wheels above
30 mph (48 km/h). Do not spin the wheels continu-
ously for more than 30 seconds.
TOWING A DISABLED VEHICLE
With Ignition Key
Automatic And Manual Transaxle
Front-wheel-drive vehicles must have the front wheels
elevated; Four-wheel-drive vehicles must be hauled on a
flatbed truck.
306 WHAT TO DO IN EMERGENCIES

Temperature Grades
The temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance, which all
passenger car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B and A repre-
sent higher levels of performance on the laboratory test
wheel than the minimum required by law.WARNING!
The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
