a CHECK TPM SYSTEM message for three sec-
onds and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a
chime will sound, the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds
and then remain on solid, and the EVIC will
display a CHECK TPM SYSTEM message for
three seconds and then display dashes (- -) in
place of the pressure value.
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 automati-
cally. In addition, the Tire Pressure Monitoring
Telltale Light will turn OFF and the graphic in the
EVIC will display a new pressure value instead of
dashes (- -), 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 10 minutes above 15 mph (25
km/h) in order for the TPMS to receive this infor-
mation.
TPMS Deactivation & Reactivation
The TPMS can be deactivated if replacing all four
wheel and tire assemblies (road tires) with wheel
and tire assemblies that do not have TPMS Sen-
sors, such as when installing winter wheel and tire
assemblies on your vehicle.
To deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with those
not equipped with TPM Sensors. Then, drive the
vehicle for 10 minutes above 15 mph (25 km/h).
The TPMS will chime and the Tire Pressure Moni-
toring Telltale Light will flash on and off for 75
seconds and then remain on solid. In addition, the
Electronic Vehicle Information Center (EVIC) will
display a "CHECK TPM SYSTEM" text message,
and the graphic will display "- -" in place of four
tire pressure values. Upon the next ignition key
cycle, the TPMS will no longer chime or turn on the
Tire Pressure Monitoring Telltale Light, or display
the text message in the EVIC. However, the
graphic will still display "- -."
To reactivate the TPMS, first, replace all four wheel
and tire assemblies (road tires) with those
equipped with TPM Sensors. Then, drive the ve-
hicle for up to 10 minutes above 15 mph (25
km/h). The TPMS will chime, the Tire Pressure
Monitoring Telltale Light will flash on and off for 75
seconds, the EVIC will display a "CHECK TPM
SYSTEM" text message, and the graphic will
display tire pressure values to show that the TPMS
is receiving sensor data.
General Information
Transmitter and receivers operate on a carrier
frequency of 433.92 MHz as required by EEC
regulations. These devices must be certified to
conform to specific regulations in each individual
country. Two sets of regulations are involved: ETS
(European Telecommunication
300–220, which most countries use, and German
BZT federal regulation 225Z125, which is based
on ETC 300–220 but has additional unique re-
quirements. Other defined requirements are noted
in ANNEX VI of COMMISSION DIRECTIVE 95/56/
EC. Operation is subject to the following two
conditions:
• This device may not cause harmful interfer-
ence.
• This device must accept any interference re-
ceived, including interference that may cause
undesired operation.
FUEL REQUIREMENTS
Your vehicle is designed to meet all emission
regulations and provide excellent fuel economy
when using high quality unleaded gasoline with a
minimum research octane rating of 91.
The vehicle will operate on fuels ranging from
regular unleaded having a minimum research
octane of 91 to premium unleaded with a mini-
mum research octane of 98.
Over 40 automobile manufacturers around the
world have issued and endorsed consistent gaso-
line specifications (the World Wide Fuel Charter,
WWFC) to define fuel properties necessary to
deliver enhanced emissions, engine perfor-
mance, and durability for your vehicle. The manu-
