Tire Pressure Monitoring System (TPMS) Warning Light
Yellow TelltaleLight What It Means
Tire Pressure Monitoring System (TPMS) Warning Light
The warning light switches on and a message is displayed to indicate that the tire pressure
is lower than the recommended value and/or that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the
indications corresponding to each tire in sequence.
CAUTION!
Do not continue driving with one or more flat tires
as handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Repair imme-
diately using the dedicated tire repair kit and con-
tact your authorized dealer as soon as possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
130 UNDERSTANDING YOUR INSTRUMENT PANEL

Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, 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
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indica-
tor is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continu-
ously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur for
a variety of reasons, including the installation of re-
placement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly. Al-
ways check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle toensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function prop-
erly.
CAUTION!
The 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 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 dealer to have your
sensor function checked.4

to stop on wet pavement, as measured under con-
trolled conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C may
have poor traction performance.
WARNING!
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and does
not include acceleration, cornering, hydroplan-
ing, or peak traction characteristics.
Temperature Grades
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat, when tested
under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature
can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead
to sudden tire failure. The grade C corresponds to a
level of performance, which all passenger vehicle
tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test
wheel, than the minimum required by law.
WARNING!
The temperature grade for this tire is established
for a tire that is properly inflated and not over-
loaded. Excessive speed, under-inflation, or ex-
cessive loading, either separately or in combina-
tion, can cause heat buildup and possible tire
failure.
TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
The tire pressure will vary with temperature by about
1psi (7 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mile
(1.6 km) after a three hour period. The cold tire inflation
210 STARTING AND OPERATING

pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall. Refer to “Tires –
General Information” in “Starting And Operating” for
information on how to properly inflate the vehicle’s
tires. The tire pressure will also increase as the vehicle is
driven. This is normal and there should be no adjust-
ment 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
limit for any reason, including low temperature effects
and natural 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 the
recommended cold placard pressure. Once the low tire
pressure warning (Tire Pressure Monitoring Telltale
Light) illuminates, you must increase the tire pressure
to the recommended cold placard pressure in order for
the “Tire Pressure Monitoring Telltale Light” to turn off.
The system will automatically update and the “Tire
Pressure Monitoring Telltale Light” will turn off once
the system receives the updated tire pressures. Thevehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pres-
sure of 33 psi (227 kPa). If the ambient temperature is
68°F (20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn ON
the “Tire Pressure Monitoring Telltale Light.” Driving
the vehicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the “Tire Pressure
Monitoring Telltale Light” will still be on. In this
situation, the “Tire Pressure Monitoring Telltale Light”
will turn off only after the tires are inflated to the
vehicle’s recommended cold placard 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

CAUTION!(Continued)
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. The TPM sensor is
not designed for use on aftermarket wheels and
may contribute to a poor overall system perfor-
mance or sensor damage. Customers are encour-
aged to use OEM wheels to assure proper TPM
feature operation.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
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 moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring 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 the high voltage battery
range and tire tread life, and may affect the vehicle’s
handling and stopping ability.
• It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
• 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
gauge, 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 pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
212 STARTING AND OPERATING

TPM System
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.
The TPMS consists of the following components:
•Receiver module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime will
sound when tire pressure is low in one or more of the
four active road tires. In addition, the instrument
cluster will display a low pressure graphic showing
the low tire pressure tire highlighted in a different
color.
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure to the vehicle’s
recommended cold placard pressure value. Once the
system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale Light” will turn off. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this infor-
mation.

TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
sound a chime and also display a “Service Tire Pressure
Monitoring System” message in the instrument cluster
for approximately 5 seconds.
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, and the “Service TPM
System” message will no longer display.A system fault can occur due to any of the following:
1. Signal interference due to electronic devices or driv-
ing next to facilities emitting the same radio frequen-
cies as the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
• The TPMS will not monitor the pressure in a replace-
ment tire installed without a tire pressure sensor.
• If you install a replacement 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
and a chime will sound. In addition, the highlighted
graphic in the instrument cluster will still display a
low pressure text message and a pressure value in a
different color.
