WARNING/INDICATOR
LIGHTS AND MESSAGES
IMPORTANT: The warning/indicator light
switches on in the instrument panel together
with a dedicated message and/or acoustic
signal when applicable. These indications
are indicative and precautionary and as such
must not be considered as exhaustive and/or
alternative to the information contained in
the Owner Manual, which you are advised to
read carefully in all cases. Always refer to the
information in this chapter in the event of a
failure indication.
All active telltales will display first, if appli-
cable. The system check menu may appear
different based upon equipment options and
current vehicle status. Some telltales are
optional and may not appear.
Red Telltale Lights
– Seat Belt Reminder Warning Light
When the ignition switch is first turned to
ON/RUN, this light will turn on for four to
eight seconds as a bulb check. During the
bulb check, if the driver's seat belt is unbuck- led, a chime will sound. After the bulb check
or when driving, if the driver’s seat belt re-
mains unbuckled, the Seat Belt Reminder
Light will flash or remain on continuously and
a chime will sound.
– Air Bag Warning Light
This light will turn on for four to eight sec-
onds as a bulb check when the ignition
switch is first turned to ON/RUN. If the light
is either not on during startup, stays on, or
turns on while driving, have the system in-
spected at an authorized dealer as soon as
possible. This light will illuminate with a
single chime when a fault with the Air Bag
Warning Light has been detected, it will stay
on until the fault is cleared. If the light comes
on intermittently or remains on while driving,
have an authorized dealer service the vehicle
immediately.
– Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
GETTING TO KNOW YOUR INSTRUMENT PANEL
80

indicate that the parking brake is applied,
that the brake fluid level is low, or that there
is a problem with the anti-lock brake system
reservoir.
If the light remains on when the parking
brake has been disengaged, and the fluid
level is at the full mark on the master cylinder
reservoir, it indicates a possible brake hy-
draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair
is necessary.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired. Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
two seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by an autho-
rized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.

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.
– Engine Temperature Warning Light
This light warns of an overheated engine
condition. As engine coolant temperatures
rise and the gauge approachesH,this indica-
tor will illuminate and a single chime will
sound after reaching a set threshold.
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 Temperature Warning Light
This telltale indicates engine oil temperature
is high. If the light turns on while driving,
stop the vehicle and shut off the engine as
soon as possible.
– Battery Charge Warning Light
This light illuminates when the battery is not
charging properly. If it stays on while the
engine is running, there may be a malfunc-
tion with the charging system. Contact your
authorized dealer as soon as possible. This
indicates a possible problem with the electri-
cal system or a related component.
If jump starting is required, refer to “Jump-
Starting” in “In Case Of Emergency.”
– Electronic Throttle Control (ETC)
Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is run-
ning, the light will either stay on or flash
depending on the nature of the problem.
Cycle the ignition key when the vehicle is
safely and completely stopped and the trans- mission is placed in the PARK position. The
light should turn off. If the light remains on
with the vehicle under power, your vehicle
will usually be drivable; however, see an au-
thorized dealer for service as soon as pos-
sible.
If the light continues to flash when the en-
gine vehicle under power, immediate service
is required and you may experience reduced
performance, and your vehicle may require
towing. The light will come on when the

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.
– Hood Open Warning Light
This indicator will illuminate when the hood
is left open and not fully closed.
Yellow Telltale Lights
– Engine Malfunction Warning Light
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 position before engine start. If the
bulb does not come on when turning the key
from OFF to ON/RUN, have the condition
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.
83

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 engine 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
The “ESC Indicator Light” in the instrument
cluster will come on when the ignition switch
is turned to the ON/RUN position. It should
go out when the engine is 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 switch is
turned to ON/RUN.
• Each time the ignition is turned to ON/ RUN, the ESC system will be ON, even if it
was turned off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
This telltale indicates that an ESC event is
active.
– Electronic Stability Control (ESC) OFF
Indicator Light — If Equipped
This light indicates the Electronic Stability
Control (ESC) is off.
– 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 se-
quence.
IMPORTANT: Do not continue driving with one
or more flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp brak-
ing and steering. Repair immediately using
the dedicated tire repair kit and contact your
authorized dealer as soon as possible.
GETTING TO KNOW YOUR INSTRUMENT PANEL
84

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 tiresor 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 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
an authorized dealer to have your sensor
function checked.

This light monitors the Anti-Lock Brake Sys-
tem (ABS). The light will turn on when the
ignition switch is placed in the 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
