NOTE:
If the vehicle is moving and a door is opened,
there will also be a single chime.
— Electronic Throttle Control (ETC)
Warning Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the vehicle is run-
ning, the light will either stay on or flash
depending on the nature of the problem.
Cycle the ignition when the vehicle is safely
and completely stopped and the transmission
is placed in the PARK position. The light
should turn off. If the light remains on with
the vehicle running, your vehicle will usually
be drivable; however, see an authorized
dealer for service as soon as possible.
If the light continues to flash when the ve-
hicle is running, immediate service is re-
quired and you may experience reduced per-
formance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The
light will come on when the ignition is placed
in the ON/RUN or MAR/ON/RUN position and remain on briefly as a bulb check. If the light
does not come on during starting, have the
system checked by an authorized dealer.
— Engine Temperature Warning Light
This light warns of an overheated engine
condition. If the engine coolant temperature
is too high, this indicator will illuminate and a
single chime will sound. If the temperature
reaches the upper limit, a continuous chime
will be sound for four minutes or until the
engine is allowed to cool whichever comes
first.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission
into NEUTRAL and idle the vehicle. If the
temperature reading does not return to nor-
mal, turn the engine off immediately and call
for service. Refer to “If Your Engine Over-
heats” in “In Case Of Emergency” for further
information.
— Oil Pressure Warning Light
This light indicates low engine oil pressure. If
the light turns on while driving, stop the
vehicle and shut off the engine as soon as
possible. A chime will sound when this light
turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
— Transmission Temperature Warning
Light — If Equipped
This light indicates that there is excessive
transmission fluid temperature that might
occur with severe usage such as trailer tow-
ing. If this light turns on, stop the vehicle and
run the engine at idle or slightly faster, with
the transmission in PARK or NEUTRAL, until
the light turns off. Once the light turns off,
you may continue to drive normally.
WARNING!
If you continue operating the vehicle when

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.
— Seat Belt Reminder Warning Light
When the ignition is first placed in the ON/
RUN or MAR/ON/RUN position, if the driver’s
seat belt is unbuckled, a chime will sound
and the light will turn on. When driving, if the
driver or front passenger seat belt remains
unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime
will sound. Refer to “Occupant Restraints
Systems” in “Safety” for further information.
— Transmission Fault Warning Light
This light will illuminate (together with a
message in the instrument cluster display
and a buzzer) to indicate a transmission
fault. Contact your authorized dealer if the
message remains after restarting the engine.
— Engine Oil Level Warning Light
This warning light appears on the panel when
the engine oil level falls below the minimum
recommended value. Restore the correct en-
gine oil level or contact your authorized
dealer for service.
Yellow Warning Lights
— Anti-Lock Brake (ABS) Warning
Light
This light monitors the Anti-Lock Brake Sys-
tem (ABS). The light will turn on when the
ignition is placed in the ON/RUN or MAR/ON/
RUN position and may stay on for as long as
four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the
brake system is not functioning and service is required. However, the conventional brake
system will continue to operate normally if
the brake warning light is not on.
If the ABS light is on, the brake system
should be serviced as soon as possible to
restore the benefits of Anti-Lock Brakes. If
the ABS light does not turn on when the
ignition is placed in the ON/RUN or MAR/ON/
RUN position, have the light inspected by an
authorized dealer.
— Low Fuel Warning Light
When the fuel level reaches approximately
2–6 gal (9–11 L) this light will turn on, and
remain on until fuel is added.
— Generic Warning Light
The Generic Warning Light will illuminate if
any of the following conditions occur: Engine
Oil Pressure Sensor Failure, External Light
Failure, Parking Sensor Failure, DST System
Failure, Stop/Start failure, or Air Bag telltale
recovery.
The telltale will blink in case of Air Bag
Warning Light Failure. Contact an authorized
dealer immediately for service.

— Tire Pressure Monitoring System
(TPMS) Warning 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 con-
sumption 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.
CAUTION!
Do not continue driving with one or more
flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp
braking and steering. If a tire puncture
occurs, repair immediately using the dedi-
cated tire repair kit and contact your au-
thorized dealer as soon as possible.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the vehicle placard or tire inflation pressure la-
bel. (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 monitor-
ing 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 illu-
minates, 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 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 approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent ve-
hicle 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 replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion 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.
35

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 opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. After-
market 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 your authorized dealer to have your
sensor function checked.
— Vehicle Security Warning Light
This telltale will illuminate when the vehicle
security alarm system has detected an at-
tempt was made to break into the vehicle.
— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
The light will illuminate when the ignition is
in the ON/RUN position before engine start.
If the bulb does not come on when turning
the key from OFF to ON/RUN, have the con-
dition checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced as soon as possible if this
occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.

— Electronic Stability Control (ESC)
Warning Light — If Equipped
The “ESC Indicator Light” in the instrument
cluster will come on when the ignition is
placed in the ON/RUN or MAR/ON/RUN po-
sition, and when ESC is activated. It should
go out with the engine running. If the “ESC
Indicator Light” comes on continuously with
the engine running, a malfunction has been
detected in the ESC system. If this light
remains on after several ignition cycles, and
the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon
as possible to have the problem diagnosed
and corrected.
• The “ESC Off Indicator Light” and the “ESC Indicator Light” come on momen-
tarily each time the ignition is placed in the
ON/RUN or MAR/ON/RUN position.
• Each time the ignition is turned to ON/RUN or MAR/ON/RUN, the ESC system will be
on, even if it was turned off previously. • The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive.
• This light will come on when the vehicle is in an ESC event.
— Electronic Stability Control (ESC) Off
Warning Light — If Equipped
This light indicates the Electronic Stability
Control (ESC) is off.
Each time the ignition is turned to ON/RUN
or ACC/ON/RUN, the ESC system will be on,
even if it was turned off previously.
Yellow Indicator Lights
— Cold Start Inhibitor — If Equipped
This vehicle will inhibit engine cranking when
the ambient temperature is less than –22° F
(–30° C) and the oil temperature sensor read-
ing indicates an engine block heater has not
been used. The Cold Start Inhibitor light will
flash during in cold weather for up to 10 sec-
onds. If equipped with a block heater harness the
message "Engine Heater Recommended",
will be displayed in the instrument cluster
when the ambient temperature is below 5°F
(-15° C) at the time the engine is shut off as
a reminder to avoid possible crank delays at
the next cold start.
Green Indicator Lights
— Turn Signal Indicator Lights
The turn signal arrows will flash indepen-
dently when left or right turn signals are
selected. Turn signals can be activated when
the multifunction lever is moved down (left)
or up (right).
NOTE:
• A continuous chime will sound if the ve-
hicle is driven more than 1 mile (1.6 km)
with either turn signal on.
• Check for an inoperative outside light bulb if either indicator flashes at a rapid rate.
— Park/Headlight On Indicator Light
This indicator will illuminate when the park
lights or headlights are turned on.

This indicator shows that the high beam
headlights are on. With the low beams acti-
vated, push the multifunction lever forward
(toward the front of the vehicle) to turn on the
high beams. Pull the multifunction lever rear-
ward (toward the rear of the vehicle) to turn
off the high beams. Pull the lever toward you
for a temporary high beam on, "flash to pass"
scenario.
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 govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light (MIL). It will also store diag-
nostic codes and other information to assist
your service technician in making repairs.
Although your vehicle will usually be drivable
and not need towing, see your authorized
dealer for service as soon as possible.
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 dam-
age and power loss will soon occur. Im-
mediate service is required.
Onboard Diagnostic System (OBD
II) Cybersecurity
Your vehicle is required to have an Onboard
Diagnostic system (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.

AUXILIARY DRIVING SYSTEMS
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 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 the outside tempera-
ture 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 pres-
sure molded into the tire sidewall. 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 limit for any reason,
including low temperature effects and natu-
ral 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 pres-
sure warning (Tire Pressure Monitoring [TPM]
Telltale Light) illuminates, you must increase
the tire pressure to the recommended cold
placard pressure in order for the TPM Telltale
Light to turn off. The system will automati-
cally update and the TPM 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.
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 plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.
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 approxi-
mately 23 psi (158 kPa). This tire pressure is
sufficiently low enough to turn on the TPM
Telltale Light. Driving the vehicle may cause
the tire pressure to rise to approximately
27 psi (186 kPa), but the TPM Telltale Light
will still be on. In this situation, the TPM
Telltale Light will turn off only after the tires
are inflated to the vehicle’s recommended
cold placard pressure value.
SAFETY
42

CAUTION!
• The TPMS has been optimized for theoriginal equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion 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 Sys-
tem (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.
• 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 TPMS sensor. NOTE:
• The TPMS is not intended to replace nor-
mal 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
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 respon-
sibility 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 TPM 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.
