2010 JEEP COMPASS tire pressure

fault is detected. The system fault will also sound a
chime. If the ignition key is cycled, this sequence will
repeat providing the system fault still exists. The Tire
Pressure Monitoring Telltale Light will turn off when the
fault condition no longer exists. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:Your vehicle is equipped with a compact spare
wheel and tire assembly. 1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the tire pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will still turn ON due to the low tire.
3. However, after driving the vehicle for up to 20 min-
utes above 15 mph (25 km/h), the Tire Pressure Moni-
toring Telltale Light will flash on and off for 75 seconds
and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid.
330 STARTING AND OPERATING

5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will update automatically and the Tire
Pressure Monitoring Telltale Light will turn OFF, as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(25 km/h) in order for the TPMS to receive this
information.
Premium System – If Equipped
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. 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:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Three Trigger Modules (mounted in three of the four
wheel wells)
•Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
•Yellow Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light 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 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 all tires that are 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 Light will extin-
guish once the updated tire pressure(s) have been re-
ceived. The vehicle may need to be driven for up to
20 minutes above 15 mph (25 km/h) to receive this
information.
Check TPMS Message
The Tire Pressure Monitoring Telltale Light 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 “CHECK TPM SYS-
TEM” message for three seconds. This text message is
then followed by a graphic display, with “- -“ in place of
the pressure value(s) indicating which Tire Pressure
Monitoring Sensor(s) is not being received.

332 STARTING AND OPERATING

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, theCHECK TPM SYSTEM
text message will not be present, and a pressure value will be displayed instead of dashes. A system fault can
occur with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
Your vehicle is equipped with a compact spare
wheel and tire assembly.
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the tire pressure in the compact spare tire.

2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will still turn ON due to the low tire.
3. However, after driving the vehicle for up to 20 min-
utes above 15 mph (25 km/h), the Tire Pressure Moni-
toring Telltale Light will flash on and off for 75 seconds
and then remain on solid. In addition, the EVIC will
display a “CHECK TPM SYSTEM” message for three
seconds and then display dashes (- -) in place of the
pressure values.
4. For each subsequent ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on

FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high-quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended, as it will not provide any
benefit over regular gasoline in these engines.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasoline contains oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The manufacturer supports the use of reformulated gaso-
line. Properly blended reformulated gasoline will pro-
vide excellent performance and durability of engine and
fuel system components.
