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 20 minutes above 15 mph
(25 km/h). The TPMS will chime and the Tire
Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and then remain on
solid. In addition, the Electronic Vehicle Infor-
mation 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 switch 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 vehicle for up to 20 minutes above 15 mph
(25 km/h). The TPMS will chime, the Tire Pres-
sure 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 indi-
vidual country. Two sets of regulations are
involved: ETS (European Telecommunication
Standard) 300–220, which most countries use,
and German BZT federal regulation 225Z125,
which is based on ETC 300–220 but has addi-
tional unique requirements. Other defined re-
quirements are noted in ANNEX VI of COMMIS-
SION 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
received, including interference that may
cause undesired operation.
FUEL REQUIREMENTS —
GASOLINE ENGINES

2.4L and 2.7L Engines

All engines are designed to meet all emissions
regulations and provide excellent fuel economy
and performance when using high quality un-
leaded gasoline with a minimum research oc-
tane rating of 91. 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 before considering service for the
vehicle.
Over 40 auto manufacturer's world wide have
issued and endorsed consistent gasoline
specifications (the Worldwide Fuel Charter,
WWFC) which define fuel properties necessary
to deliver enhanced emissions, performance,
and durability for your vehicle. The manufac-
turer recommends the use of gasoline that
meets the WWFC specifications if they are
available.
