Tire Pressure Monitoring Indicator Light
Yellow TelltaleLight What It Means
Tire Pressure Monitoring Indicator 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 indica-
tions corresponding to each tire in sequence.
IMPORTANT: Do not continue driving with one or more
flat tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. Repair im-
mediately using the dedicated tire repair kit and contact
your authorized dealership 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 pressure label, you
should determine the proper tire inflation 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. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible and
inflate them to the proper pressure. Driving on a signifi-
cantly 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.
112 UNDERSTANDING YOUR INSTRUMENT PANEL

Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain 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 indicator 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. Always
check the TPMS malfunction telltale after replacing oneor more tires or wheels on your vehicle, to ensure that
the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
CAUTION!
The TPMS has been optimized for the original equip-
ment 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 equip-
ment 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 inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealership to have your sensor function checked.4

174 STARTING AND OPERATING

The suggested rotation method is the “forward cross”
shown in the following diagram. This rotation pattern does
not apply to some directional tires that must not be
reversed.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold tire pressure.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when theoutside temperature decreases, the tire pressure will de-
crease. 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 pressure must not exceed the
maximum inflation pressure 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
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 limit for
any reason, including low temperature effects, or 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 tire pressure on the placard. Once the low tire pressure
warning (Tire Pressure Monitoring Telltale Light) illumi-
nates, you must increase the tire pressure to the recom-
mended cold tire 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. 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.
For example, your vehicle may have a recommended cold
(parked for more than three hours) tire pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (159 kPa). This tire pressure is suffi-
ciently low enough to turn on the Tire Pressure Monitoring
Telltale Light. Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 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 tire pressure value.

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, al-
ways 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.
220 STARTING AND OPERATING

•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 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 pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Base System
This is the TPMS warning indicator located in the
instrument cluster.
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 the tires on your vehicle regularly and to
maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Five Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illuminate
in the instrument cluster, an audible chime will be acti-
vated, and the “Check tire pressure” text message will
display 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 placard pressure value. The system will
automatically update and the Tire Pressure Monitoring
Light will extinguish once the updated tire pressures have
been received. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive this
information.

STARTING AND OPERATING 221

Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected, an audible chime will be activated and the
“Tire Pressure Monitoring Unavailable” text message will
display. If the ignition key 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:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. 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: Your vehicle is equipped with a regular size spare
wheel. 1. The spare tire has a tire pressure monitoring sensor, but
it is not monitored until it is mounted in place of any of
the existing four road tires.
2. If you install the spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon
the next ignition key cycle, a chime will sound and the
Tire Pressure Monitoring Telltale Light will turn ON due
to the low tire condition. Then, after driving the vehicle
for up to 20 minutes above 15mph (24km/h), the system
will recognize the new sensor, and turn off the telltale.
3. If a spare tire not equipped with tire pressure monitor- ing sensor is used, then the Tire Pressure Monitoring
Telltale Light will turn ON, flashing for 75 seconds and
then remaining solid for each subsequent ignition key
cycle.
NOTE: For correct Tire Pressure Monitoring behavior,
please wait for about 20 minutes in key-off during each tire
substitution.
