The EVIC, odometer, and navigation system units can be
changed between English and Metric.
Press and hold the EVIC button when in this display until
“US” or “METRIC” appears to make your selection.
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 cause the compass to give false
readings. In order to ensure compass accuracy, the com-
pass variance should be set to the zone number on the
compass variance map that corresponds to the current
location of the vehicle.
NOTE:Magnetic materials should be kept away from
the Instrument Panel. This is where the compass sensor is
located.

placard 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 °F (241
kPa). If the ambient temperature is 68 °F (20 °C) and the
measured tire pressure is 30 psi (207 kPa), a temperature
drop to 20 °F (-7 °C) will decrease the tire pressure to
approximately 26 psi (179 kPa). This tire pressure is
sufficiently low enough to turn ON the “Tire Pressure
Monitoring Light”. Driving the vehicle may cause the tire
pressure to rise to approximately 30 psi (207 kPa), but the
“Tire Pressure Monitoring Light” will still be ON. In this
situation, the “Tire Pressure Monitoring Light” 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:
•Receiver Module
•4 Tire Pressure Monitoring Sensors
•3 Trigger Modules (mounted in three of the four wheel
wells)
270 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, and theCHECK TPM SYS-
TEMtext message will no longer display.
NOTE:Your system can be set to display pressure units
in PSI, kPa, or BAR.
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 “Tire Pressure Monitoring Lamp” 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) willdisplay a “CHECK TPM SYSTEM” text message on the
EVIC. This text message will then be followed by a
graphic, with “- -“ in place of the flashing low pressure
value. For every subsequent key cycle, the “Tire Pressure
Monitoring Lamp” will be ON, a chime will sound, a
“CHECK TPM SYSTEM” text message will be display in
the EVIC, and the graphic display will have “- -“ 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 “- -“, and the
“Tire Pressure Monitoring Lamp” 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.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do
not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to
the sensors may result.
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 wheel rim sensor.
NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The 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.
274 STARTING AND OPERATING

•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the Tire
Pressure Monitoring Telltale lamp.
•Seasonal temperature changes will affect tire pressure,
and the TPM system will monitor the actual tire
pressure in the tire.
General Information
This device complies with part 15 of the FCC rules and
RSS 210 of Industry Canada. Operation is subject to the
following conditions:
•This device may not cause harmful interference.
•This device must accept any interference received,
including interference that may cause undesired op-
eration.The tire pressure sensors are covered under one of the
