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
using replacement equipment that is not of the
same size, type, and/or style. After-market 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.
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
Monitoring Sensor.
NOTE:
²
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS 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.
²The 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 light.
Base System Ð If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
232 STARTING AND OPERATING

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 regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and an audible
chime will sound when tire pressure is low in one
or more of the four active road tires. The audible chime
will sound once every ignition cycle for each condition
that it detects. 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 recom-
mended cold placard pressure value. Once the systemreceives the updated tire pressures, the system will
automatically update and the Tire Pressure Monitoring
Telltale 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. Low
pressure in the spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate or the chime to
sound.
NOTE: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. However, if you install the compact spare tire in
place of a road tire that has a pressure below the
low-pressure warning limit, the Tire Pressure Monitoring
Telltale Light will remain ON and a chime will still sound
each ignition key cycle. 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 Tire Pressure Monitoring Telltale Light will turn
OFF, as long 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
information.
Check TPMS Warning
The Tire Pressure Monitoring Telltale Light will flash on
and off for 60 seconds and an audible chime will sound
when a system fault is detected. The flash cycle will
repeat every ten minutes, without an audible chime, until
the fault condition no longer exists. If the ignition key is
cycled, this sequence will repeat, providing the system
fault still exists.
Premium 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 regularly
and to maintain the proper pressure.
The TPMS consists of the following components:

Center (EVIC)
²Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and an audible
chime will sound when tire pressure is low in one
or more of the four active road tires. The audible chime
will sound once every ignition cycle for each condition
that it detects. In addition, the Electronic Vehicle Infor-
mation Center (EVIC) will display one or more Low
Pressure messages (Left Front, Left Rear, Right Front,
Right Rear) for 3 seconds and a graphic showing the
pressure values of each tire with the low tire pressure
values flashing. Should this occur, you should stop as
soon as possible, and inflate the tires with low pressure
234 STARTING AND OPERATING

(those flashing in the EVIC graphic) to the vehicle's
recommended cold placard pressure value. Once the
system receives the updated tire pressures, the system
will automatically update, the graphic display in the
EVIC will stop flashing, and the Tire Pressure Monitoring
Telltale 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. Low
pressure in the spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate or the chime to
sound.NOTE:
²
You can change the pressure units to display in PSI,
kPA, or BAR. Refer to ªLanguage,º under ªPersonal
Settings (Customer Programmable Features),º under
ªElectronic Vehicle Information Center (EVIC)º in
Section 4 of this manual for details.
²The 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.
However, if you install the compact spare tire in place
of a road tire that has a pressure below the low-
pressure warning limit, the Tire Pressure Monitoring
Telltale Light will remain ON and a chime will still
sound each ignition key cycle. In addition, the EVIC
will still display a low-pressure message and a flash-
ing pressure value in the graphic display. 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 Tire Pres-
sure Monitoring Telltale Light will turn OFF, and the
graphic in the EVIC will stop flashing and display a
new pressure value, as long 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 information.
Check TPMS Warning
The Tire Pressure Monitoring Telltale Light will flash on
and off for 60 seconds and an audible chime will sound
when a system fault is detected. The flash cycle will
repeat every ten minutes, without an audible chime, until
the fault condition no longer exists. In addition to the
telltale and chime, the Electronic Vehicle Information
Center (EVIC) will display a9CHECK TPM SYSTEM9
message for 3 seconds when a system fault is detected. In
the event that a fault occurs because the system did not
receive a pressure value from one or more Tire Pressure
Monitoring Sensors, the EVIC will display the9CHECK
TPM SYSTEM9message and then display dashes (- -) in
place of the pressure value to indicate which sensor is not
being received.
NOTE:You can change the pressure units to display in
PSI, kPA, or BAR. Refer to ªLanguage,º under ªPersonal
Settings (Customer Programmable Features),º under
ªElectronic Vehicle Information Center (EVIC)º in Sec-
tion 4 of this manual for details.
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 the9CHECK TPM SYS-
TEM9message will no longer display, and a pressure
value will display in place of the dashes.

FUEL REQUIREMENTS
6.1L Engine
The 6.1L engine is designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high-quality premium unleaded
gasoline with an octane rating of 91 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 experience these
symptoms, try another brand of ªpremiumº gasoline
before considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
STARTING AND OPERATING 237

content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer if his/her gasoline
contains MMT.
It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than allowed in the United States. MMT is pro-
hibited in Federal and California reformulated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and they would result in additional
cost. Therefore, you should not have to add anything to
the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²The use of fuel additives, which are now being sold as
octane enhancers, are not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives are not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
STARTING AND OPERATING 239

CAUTION!
²Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap).
²A poorly fitting gas cap could let impurities into
the fuel system.
²A poorly fitting gas cap may cause the Malfunc-
tion Indicator Light to turn on.
²To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling. When the fuel
nozzle ªclicksº or shuts off, the fuel tank is full.
WARNING!
²Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
²Never add fuel to the vehicle when the engine is
running.
²A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
NOTE:
²
Tighten the gas cap until you hear a ªclickingº sound.
This is an indication that the gas cap is tightened
properly. The Malfunction Indicator Light in the in-
strument cluster may turn on if the gas cap is not
secured properly. Make sure that the gas cap is tight-
ened each time the vehicle is refueled.
²When the fuel nozzle ªclicksº or shuts off, the fuel
tank is full.
