2. Press and release the EVIC button several times until
the EVIC displays the Personal Settings (Customer Pro-
grammable Features) menu.
3. Press and release the EVIC button several times until
ªCalibrate Compass (Yes)º is displayed. A long (longer
than two seconds) EVIC button Press will place the
Compass in calibration mode.
4. The ªCALº 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 the9Calibrate
Compass (Yes)9screen will 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 ªCALº indicator turns
off. The compass will now function normally.Compass Variance
Compass Variance is the difference between magnetic
North and Geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to introduce some compass error.
In order to ensure compass accuracy, the compass vari-
ance should be properly set according to the variance
zone map for the vehicle's current location. The compass
in your vehicle will now automatically compensate for
this difference.
NOTE:Magnetic materials such as a laptop computer,
cell phone, and PDA's (anything with a battery), should
be kept away from the top of the instrument panel. This
is where the compass sensor is located.

driven for up to 10 minutes above 15 mph (25 km/h)
in order for the TPMS to receive this information.
þFor example, your vehicle may have a recom-
mended cold (parked for more than three hours)
placard pressure of 33 psi (227 kPa). If the ambient
temperature is 68É F (20É C) and the measured tire
pressure is 28 psi (193 kPa), a temperature drop to
20É F (-7É C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure is
sufficiently low enough to turn ON the TPM Light.
Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the TPM
Light will still be ON. In this situation, the TPM
Light will turn OFF only after the tires are inflated to
the vehicle's recommended cold placard pressure
value.
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:
²TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
²TPMS 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.
²TPMS 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 TPM Light.
²Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
BASE SYSTEM Ð 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 the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
²Receiver Module
²Four Tire Pressure Monitoring Sensors
²Tire Pressure Monitoring Telltale Light
334 STARTING AND OPERATING

Tire Pressure Monitoring Low Pressure Warnings
The TPM 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 TPM Light will turn off. The vehicle may
need to be driven for up to 10 minutes above 15 mph (25
km/h) in order for the TPMS to receive this information.
Check TPMS Warning
The TPM Light will flash on and off for 75 seconds 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, providing the systemfault still exists. The TPM 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 as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials which 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 TPM sensors.
NOTE:
1. The compact spare tire (if so equipped) does not have
a tire pressure monitoring 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 TPM Telltale Light will turn ON due to the
low tire.
3. After driving the vehicle for up to 10 minutes above 15
mph (25 km/h), the TPM 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 TPM 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 TPM Telltale
Light will turn OFF, as long no tire pressure is below the
low-pressure warning limit in any of the four active roadtires. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.
