GETTING TO KNOW YOUR INSTRUMENT PANEL71

As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. 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
underinflated tire causes the tire to overheat and can
lead to tire failure. Underinflation 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 underinflation 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
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 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.

Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a
failure with the tow hook. Contact an
authorized dealer for service.
Transmission Temperature Warning Light
This warning light will illuminate to warn
of a high transmission fluid temperature.
This may occur with strenuous usage
such as trailer towing. If this light turns
on, stop the vehicle and run the engine at idle or
slightly faster, with the transmission in PARK (P) or
NEUTRAL (N), until the light turns off. Once the light
turns off, you may continue to drive normally.
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 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. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have
your sensor function checked.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is
illuminated you could cause the fluid to boil over,
come in contact with hot engine or exhaust
components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission damage
or transmission failure.

ONBOARD DIAGNOSTIC SYSTEM — OBD II

Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine
emissions well within current government regulations.

If any of these systems require service, the OBD II
system will turn on the Malfunction Indicator Light
(MIL). It will also store diagnostic codes and other
information to assist your service technician in
making repairs. Although your vehicle will usually
be drivable and not need towing, see an authorized
dealer for service as soon as possible.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY

Your vehicle is required to have an OBD II and a
connection port to allow access to information related
to the performance of your emissions controls.
Authorized service technicians may need to access this
information to assist with the diagnosis and service of
your vehicle and emissions system
Ú
page 133.

EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to
pass an inspection of your vehicle's emissions
control system. Failure to pass could prevent
vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies
the Malfunction Indicator Light (MIL) is
functioning and is not on when the
engine is running, and that the OBD II system is
ready for testing.
The OBD II system may not be ready if your vehicle
was recently serviced, recently had a depleted
battery or a battery replacement. If the OBD II
system should be determined not ready for the
I/M test, your vehicle may fail the test.
CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician should
connect equipment to the OBD II connection
port in order to read the VIN, diagnose, or
service your vehicle.
If unauthorized equipment is connected
to the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.
