Vehicles With Compact Spare
1. The compact spare tire does not have a TPM
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 switch cycle, the "TPM Telltale Light"
will remain ON and a chime will sound. In
addition, the graphic in the instrument cluster
will still display the low pressure values in a
different color.
3. After driving the vehicle for up to 10 minutes
above 15 mph (24 km/h), the "TPM Telltale
Light" will flash on and off for 75 seconds and
then remain on solid. In addition, the instru-
ment cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five
seconds and then display dashes (- -) in
place of the pressure value.
4. For each subsequent ignition switch cycle, a
chime will sound, the "TPM Telltale Light" will
flash on and off for 75 seconds and then
remain on solid, and the instrument cluster
will display a "SERVICE TPM SYSTEM"
message for a minimum of five 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
automatically. In addition, the "TPM Telltale
Light" will turn OFF and the graphic in the
instrument cluster will display a new pres-
sure 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 (24 km/h) in
order for the TPMS to receive this informa-
tion.
TPMS Deactivation — If Equipped
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 Sensors, 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 tires not
equipped with Tire Pressure Monitoring (TPM)
Sensors. Then, drive the vehicle for 10 minutes
above 15 mph (24 km/h). The TPMS will chime,
the "TPM Telltale Light" will flash on and off for
75 seconds and then remain on, and the instru-
ment cluster will display the "SERVICE TPM
SYSTEM" message and then display dashes
(--) in place of the pressure values. Beginning
with the next ignition switch cycle, the TPMS will
no longer chime or display the "SERVICE TPM
SYSTEM" message in the instrument cluster but
dashes (--) will remain in place of the pressure
values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 10 minutes above 15 mph
(24 km/h). The TPMS will chime, the "TPM
Telltale Light" will flash on and off for 75 seconds
and then turn off, and the instrument cluster will
display the "SERVICE TPM SYSTEM" mes-
sage. The instrument cluster will display pres-
sure values in place of the dashes. On the next
ignition switch cycle the "SERVICE TPM SYS-
TEM" message will no longer be displayed as
long as no system fault exists.
FUEL REQUIREMENTS
6.2L Supercharged And 6.4L Engine
The 6.2L Supercharged And 6.4L engines is
designed to meet all emissions regulations and
provide excellent fuel economy and perfor-
mance when using high-quality premium un-
leaded gasoline with an Research Octane Num-
ber (RON) of 98 or higher.
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
