vehicle’s tires. The tire pressure will also increase as the
vehicle is driven - this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects, or
natural air pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended cold
tire placard pressure. Once the low tire pressure warning
has been illuminated, the tire pressure must be increased to
the recommended cold tire placard pressure in order for
the “Tire Pressure Monitoring Telltale Light” to be turned
off.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
The system will automatically update and the “Tire Pres-
sure Monitoring Telltale Light” will extinguish once the
updated tire pressures have been received. NOTE:
The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this informa-
tion.
For example, your vehicle may have a recommended cold
(parked for more than three hours) tire placard pressure of
35 psi (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 Telltale Light.” Driving the vehicle
may cause the tire pressure to rise to approximately 30 psi
(207 kPa), but the “Tire Pressure Monitoring Telltale Light”
will still be on. In this situation, the “Tire Pressure Moni-
toring Telltale Light” will turn off only after the tires have
been inflated to the vehicle’s recommended cold tire plac-
ard pressure value.
CAUTION!
• The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size

equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS 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.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to maintain
correct tire pressure, using an accurate tire pressure
gage, even if under-inflation has not reached the level to
trigger illumination of the “Tire Pressure Monitoring
Telltale Light.”
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Base System
The 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 Basic TPMS consists of the following components:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• TPMS Telltale Warning Light
Tire Pressure Monitoring Low Tire Pressure
Warnings
The “Tire Pressure Monitoring Telltale Light”
will illuminate in the instrument cluster, a “LOW
TIRE PRESSURE” message will display in the
instrument cluster, and an audible chime will be
activated when one or more of the four active road tire
pressures are low. 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 tire placard pressure value (located on the
placard label on the driver’s-side B-Pillar).
NOTE: When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order to
turn the Tire Pressure Monitoring Telltale Light off. The system will automatically update and the “Tire Pres-
sure Monitoring Telltale Light” will extinguish once the
updated tire pressures have been received.
NOTE:
The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this informa-
tion.
SERVICE TPM SYSTEM
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. The “Tire Pressure
Monitoring Telltale Light” will turn off when the fault
condition no longer exists. A system fault can occur with
any of the following scenarios:
• Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Accumulation of excessive snow and/or ice around the
wheels or wheel housings.
394 STARTING AND OPERATING

•Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
• The compact spare tire (if equipped) does not have a
TPMS sensor. Therefore the TPMS will not monitor the
pressure in the compact spare tire.
• 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, a chime will
sound, a “LOW TIRE PRESSURE” message will be
displayed and the “Tire Pressure Monitoring Telltale
Light” will turn on.
• After driving for up to 20 minutes above 15 mph
(24 km/h), the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.
• For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then remain on solid.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will automatically update, and the “Tire Pressure Monitoring Telltale Light” will turn off as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires.
NOTE: The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) for the TPMS to receive
this information.
Premium System
The 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 to regularly check and
maintain proper tire pressure in all the tires.
The Premium TPMS consists of the following components:
• Receiver Module
• Four TPMS Sensors
• Various TPMS messages, which display in the instru-
ment cluster, and graphics displaying tire pressures
• TPMS Telltale Warning Light

TPMS Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will illumi-
nate in the instrument cluster, and an audible chime will be
activated when one or more of the four active road tire
pressures are low. In addition, the instrument cluster will
display a “LOW TIRE” message and a graphic display of
the pressure value(s) with the low tire(s) flashing, high-
lighted or shown in a different color. AnInflate Tire to XX
message will also be displayed.
Should a low tire condition occur on any of the four active
road tire(s), you should stop as soon as possible, and inflate
the low tire(s) that is flashing, highlighted or shown in a
different color on the graphic display to the vehicle’s
recommended cold tire pressure value as shown in the
Inflate Tire to XX message.
NOTE: When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order to
turn the Tire Pressure Monitoring Telltale Light off.
The system will automatically update, the graphic display
of the pressure value(s) will stop flashing or return to their
original color and the “Tire Pressure Monitoring Telltale
Light” will extinguish once the updated tire pressure(s)
have been received. NOTE:
The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this informa-
tion.
SERVICE TPM SYSTEM Message
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
The instrument cluster will display a “SERVICE TPM
SYSTEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with --in
place of the pressure value(s) indicating which TPMS
Sensor(s) is not being received.
If the ignition switch 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, the “SERVICE TPM SYSTEM” mes-
sage will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following scenarios:
• Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.

wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
• The compact spare tire (if equipped) does not have a
TPMS. Therefore, the TPMS will not monitor the pres-
sure in the compact spare tire.
• 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 “Tire
Pressure Monitoring Telltale Light” will remain on, the
“LOW TIRE” message will be displayed, a chime will
sound, and the instrument cluster will still display a
flashing, highlighted or different color pressure value
and the Inflate Tire to XX message in the graphic
display.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “Tire Pressure Monitoring Tell-
tale Light” will flash on and off for 75 seconds and then remain on solid. In addition, 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.
• For each subsequent ignition switch 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 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.
• 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 Pressure Monitoring Telltale Light” will turn off
and the graphic in the instrument cluster will display a
new pressure value instead of dashes (- -), as long no tire
pressure is below the low pressure warning limit in any

STARTING AND OPERATING 397

NOTE:The driver’s side sliding door cannot be opened
while the fuel door is open. This feature operates only
when the sliding door is fully closed prior to opening the
fuel door.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap. A poorly fitting cap could let
impurities into the fuel system and may cause the
“Malfunction Indicator Light (MIL)” to turn on, due
to fuel vapors escaping from the system.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the MIL to turn on.
• A 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.

WHAT TO DO IN EMERGENCIES 447

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and automatic trans-
mission control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be drivable and not need towing,
see your authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Cybersecurity” in the
“Understanding Your Instrument Panel” section.
