Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
• Tire pressure – Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle
maintenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire fail-
ure. You could lose control and have a collision
resulting in serious injury or death. Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected regu-
larly for wear and correct cold tire inflation pressures.
The manufacturer strongly recommends that you use
tires equivalent to the originals in size, quality and
performance when replacement is needed. Refer to the
paragraph on “Tread Wear Indicator” in this section.
Refer to the Tire and Loading Information placard or
the Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for your
tire will be found on the original equipment tire side-
wall.
See the Tire Sizing Chart example found in the “Tire
Safety Information” section of this manual for more
information relating to the Load Index and Speed
Symbol of a tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously

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

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.
Service TPM System Message
214 STARTING AND OPERATING

•After driving the vehicle 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. In addition, the instrument
cluster will display a “Service Tire Pressure Monitor-
ing System” message.
• 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.
Once you repair or replace the original road tire and
reinstall it, the TPMS will update automatically. In
addition, 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. 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 information.General Information
