5.Odometer / Trip Odometer Display Area
• The odometer display shows the total distance the
vehicle has been driven. The trip odometer shows
individual trip mileage. Refer to “Odometer/Trip
Odometer/ECO (Fuel Saver Indicator) Button” for
further information.
• U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser
the correct mileage that the vehicle has been driven. If
your odometer needs to be repaired or serviced, the
repair technician should leave the odometer reading
the same as it was before the repair or service. If they
cannot do so, then the odometer must be set at zero,
and a sticker must be placed in the door jamb stating
what the mileage was before the repair or service. It is
a good idea for you to make a record of the odometer
reading before the repair/service, so that you can be
sure that it is properly reset, or that the door jamb
sticker is accurate if the odometer must be reset at zero.

Tire Pressure Monitoring System (TPMS) Warning 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.
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 immedi-
ately 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.
204 GETTING TO KNOW YOUR INSTRUMENT PANEL

As an added safety feature, your vehicle has been equipped
with a Tire Pressure Monitoring System (TPMS) that illumi-
nates 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 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.
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 malfunc-
tion 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 continuously 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 todetect 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 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 dealer to have your sensor function checked.

AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
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 de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after a vehicle has not been driven for more than three
hours, or driven less than 1 mile (1.6 km) after a three-hour
period. Refer to “Tires” in “Servicing and Maintenance” 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 thresh-
old 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 turnoff until the tire pressure is at or above recommended cold
placard pressure. Once the “Tire Pressure Monitoring Tell-
tale Light” has been illuminated, the tire pressure must be
increased to the recommended cold 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. The vehicle
may need to be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) air 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 suffi-
ciently low enough to turn ON the “Tire Pressure Moni-
toring Telltale Light.” Driving the vehicle may cause the
tire pressure to rise to approximately 30 psi (207 kPa), but
5
SAFETY 227

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 have been 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 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, nor 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, 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.
