•Keep all magnetic objects, such as laptop computers,
iPod’s, cell phones and PDA’s (anything with a bat-
tery) away from the compass sensor which is located
in the top of the instrument panel. These devices can
interfere with compass accuracy and performance.
Manual Compass Calibration
If the compass appears to be inaccurate, you may wish to
manually calibrate the compass. Prior to calibrating the
compass, make sure the proper Compass Variance Value
is selected. (Refer to “Compass Variance” for additional
information). Then, continue to calibrate the compass as
follows:
1. Start the engine and leave the shift lever in the PARK
position.
2. Press and release the EVIC button several times until
the EVIC displays the Personal Settings (Customer-
Programmable Features) menu.3. Press and release the EVIC button several times until
“Calibrate Compass (Yes)” is displayed. A EVIC button
press (longer than two seconds) will place the compass in
calibration mode.
4. The CAL indicator will come on continuously in the
EVIC display, to indicate that the compass is now in the
calibration mode and that the vehicle can now be driven
to calibrate. Press the EVIC button from the
Calibrate
Compass (Yes) screen to exit the EVIC Customer-
Programmable features, and return it to its normal oper-
ating mode.)
5. Drive the vehicle slowly, under 5 mph (8 km/h),
completing one or more circles (in an area free from large
metal or metallic objects) until the “CAL” indicator turns
off. The compass will now function normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the

TPMS will continue to warn you of low tire pressure as
long as the condition exists, and will not turn off until the
tire pressure is at or above the recommended cold
placard pressure. Once the low tire pressure warning has
been illuminated, you must increase the tire pressure to
the recommended cold placard pressure in order for the
Tire Pressure Monitoring Telltale Light to turn off. The
system will automatically update and the TPMS Telltale
Light will turn off once the system receives the updated
tire pressures. 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.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pressure
of 33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi (193 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn ON the TPMSTelltale Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Telltale Light will still be ON. In this situation, the
TPMS Telltale Light will turn OFF only after the tires are
inflated to the vehicle’s recommended cold placard pres-
sure value.
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 aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
266 STARTING AND OPERATING

CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
NOTE:
•TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
•TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving 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.
•TPMS is not a substitute for proper tire maintenance,
and it is the driver ’s responsibility to maintain correct
tire pressure using an accurate tire pressure gauge,
even if under-inflation has not reached the level to
trigger illumination of the TPMS Telltale Light.
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
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 perform a
monthly tire pressure check on, and to maintain the
proper pressure of all the tires on your vehicle.

STARTING AND OPERATING 267

The TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Telltale Light will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four
active road tires. 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. Once the
system receives the updated tire pressures, the system
will automatically update and the TPMS Telltale Light
will turn off. 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.
Check TPMS Warning
The TPMS Telltale Light will flash on and off for 75 sec-
onds and then remain on solid when a system fault is
detected. The system fault will also sound a chime. If the
ignition key is cycled, this sequence will repeat, provid-
ing the system fault still exists. The TPMS Telltale Light
will turn off when the fault condition no longer exists. A
system fault can occur due to any of the following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies (RF)
as the TPMS sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Excessive accumulation of snow or ice around the
wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS Sensors.
268 STARTING AND OPERATING

NOTE:
1. The compact spare tire (if equipped) does not have a
TPMS Sensor. Therefore, the TPMS will not monitor the
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 TPMS Telltale Light will turn ON due to
the low tire.
3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h), the TPMS 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 TPMS Telltale Light will flash on and off
for 75 seconds and then remain on solid.5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the TPMS
Telltale Light will turn OFF, as long 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.

STARTING AND OPERATING 269

The tire pressure sensors are regulated under one of the
following licenses:
United States..................... KR5S120123
Canada ........................ 2671-S120123
FUEL REQUIREMENTS
2.4L And 2.4L Turbo Engines
2.4L standard engines are designed to meet
all emission regulations and provide excel-
lent fuel economy and performance when
using high quality unleaded “regular”
gasolines having an octane rating of 87.
The use of premium gasoline is not recom-
mended. Under normal conditions, the use of premium
gasoline will not provide a benefit over high quality
unleaded “regular” gasolines, and in some circumstances
may result in poorer performance.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
