Tire Pressure Monitoring Indicator Light
Yellow Telltale Light 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 recom-
mended 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.
IMPORTANT:Do not continue driving with one
or more flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp braking
and steering. Repair immediately using the
dedicated tire repair kit and contact your autho-
rized 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 pres-
sure 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. 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’sresponsibility 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 indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately 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
130

able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or 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 origi-
nal equipment tires and wheels. TPMS pres-
sures and warning have been established for
the tire size equipped on your vehicle. Un-
desirable system operation or sensor dam-
age 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 seal-
ants 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 authorized dealership to have your
sensor function checked.

play one of eight compass headings to indicate
the direction the vehicle is facing, the outside
temperature, and the current radio station.
Refer to “Personal Settings (Customer-
Programmable Features)” in this section for
additional information regarding the compass.
Average Fuel EconomyShows the average fuel economy since the last
reset (pushing and holding theRIGHTarrow
button as prompted in the EVIC display to
reset). When the fuel economy is reset, the
display will read “RESET” or show dashes for
two seconds. Then, the history information will
be erased, and the averaging will continue from
the last fuel reading before the reset.
Distance To Empty (DTE)Shows the estimated distance that can be trav-
elled with the fuel remaining in the tank. This
estimated distance is determined by a weighted
average of the instantaneous and average fuel
economy, according to the current fuel tank
level. This is not resettable.NOTE:
Significant changes in driving style or ve-
hicle loading will greatly affect the actual
drivable distance of the vehicle, regardless
of the DTE displayed value.
When the DTE value is less than 30 miles
(48 km) estimated driving distance, the DTE
display will change to a text display of"LOW
FUEL.” This display will continue until the ve-
hicle runs out of fuel. Adding a significant
amount of fuel to the vehicle will turn off the
"LOW FUEL"text and a new DTE value will be
displayed, based on the current values in the
DTE calculation and the current fuel tank level.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will
warn the driver of a low tire pressure based on
the vehicle recommended cold placard pres-
sure.
The tire pressure will vary with temperature by
about 1 psi (7.0 kPa) for every 12°F (6.5°C).
This means that when the outside temperature
decreases, the tire pressure 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 pressure must not exceed the maxi-
mum 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 thelow-pressure warning limit for any reason, in-
cluding low temperature effects, or natural pres-
sure 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 Pres-
sure Monitoring Telltale Light) illuminates, you
must increase the tire pressure to the recom-
mended 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.
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 vehicle may need to be driven for up to 10
minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.For example, your vehicle may have a recom-
mended cold (parked for more than three hours)
placard 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 (158
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 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 placard pressure value.
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.

CAUTION!
•The TPMS has been optimized for the
original equipment tires and wheels. TPMS
pressures and warning have been estab-
lished 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. Aftermarket
wheels can cause sensor damage.
•Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter 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 pres-
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the TPMS sensor.NOTE:
•The TPMS is not intended to replace nor-
mal tire care and maintenance or to pro-
vide 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 maintenance, 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 compo-
nents:
•Receiver Module.
•Four Tire Pressure Monitoring Sensors.
•Tire Pressure Monitoring Telltale Light.
205

Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, a LOW TIRE
message will be displayed for a minimum of five
seconds, 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 placard pressure value. The sys-
tem will automatically update and the Tire Pres-
sure Monitoring Light will extinguish and the
LOW TIRE message will turn off once the
updated tire pressures have been received.
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 vehicle may need to be driven for up to 10
minutes above 15 mph (24 km/h) to receive this
information.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. The
system fault will also sound a chime. 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 to facilities 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 compact
spare wheel and tire assembly.
1. The compact spare tire does not have a tire
pressure monitoring sensor. Therefore, the
TPMS will not monitor the tire pressure in the
compact spare tire.
2. 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 key cycle, a chime will sound and the
Tire Pressure Monitoring Telltale Light and
LOW TIRE message will still turn ON due to
the low tire.
3. However, after driving the vehicle for up to
10 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.
4. For each subsequent ignition key cycle, a
chime will sound and the Tire Pressure
Monitoring Telltale Light will flash on and off
for 75 seconds and then remain on solid.
206

5. 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 update
automatically and the Tire Pressure Monitor-
ing 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 10 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this informa-
tion.
Premium System — If EquippedThe 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 TPMS consists of the following compo-
nents:•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Three Trigger Modules (mounted in three of
the four wheel wells)
•Various Tire Pressure Monitoring System
Messages, which display in the Electronic
Vehicle Information Center (EVIC)
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and an au-
dible chime will be activated when one or more
of the four active road tire pressures are low.
The audible chime will sound once every igni-
tion cycle for the first condition that it detects. In
addition, the EVIC will display a “LOW TIRE”
text message for a minimum of five seconds
and a graphic of the pressure value(s) with the
low tire(s) flashing.Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible and inflate all tires that are flashing
on the graphic display to the vehicle’s recom-
mended cold placard pressure value. The sys-
tem will automatically update, the “LOW TIRE”
text message will no longer be displayed, the
graphic display of the pressure value(s) will stop
flashing, and the Tire Pressure Monitoring Light
will extinguish once the updated tire pressure(s)
have been received.
