GETTING TO KNOW YOUR VEHICLE 17

After placing the ignition in the ON/RUN position,
the vehicle security light will turn on for
three seconds for a bulb check. If the light
r e

mains on after the bulb check, it indicates
that there is a problem with the electronics.
In addition, if the light begins to flash after the
b u

lb check, it indicates that someone used an
invalid key fob to start the engine. Either of these
conditions will result in the engine being shut off
after two seconds.

If the vehicle security light turns on during
no
rmal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there
is a fault in the electronics. Should this occur,
have the vehicle serviced as soon as possible by
an authorized dealer.
All of the key fobs provided with your new
v e

hicle have been programmed to the vehicle
electronics.
KEY PROGRAMMING
Programming key fobs may be performed at an
authorized dealer.
REPLACEMENT KEYS
NOTE:
Only key fobs that are programmed to the
v e

hicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle.
NOTE:
Duplication of key fobs may be performed at an
a u

thorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has
never been programmed. When having the Sentry Key Immobilizer system
s
e

rviced, bring all vehicle keys with you to an
authorized dealer.

GETTING TO KNOW YOUR INSTRUMENT PANEL 101

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 hydraulic system malfunction or that
a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS) /
Electronic Stability Control (ESC) system. In this
case, the light will remain on until the condition 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
br

aking 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 indicated by the
Brake Warning Light, which will turn on when
the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is
c o

rrected.
NOTE:
The light may flash momentarily during sharp
c o

rnering 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
n
e

cessary.
Vehicles equipped with the Anti-Lock Brake
S y

stem (ABS) are also equipped with Electronic
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 required.
Operation of the Brake Warning Light can be
c h

ecked 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 illuminate, have
the light inspected by an authorized dealer.
The light also will turn on when the parking
b r

ake is applied with the ignition switch in the
ON/RUN position. NOTE:

This light shows only that the parking brake is
a p

plied. It does not show the degree of brake
application.
Vehicle Security Warning Light — If
Equipped
This light will flash at a fast rate for
approximately 15 seconds when the
v e

hicle security alarm is arming, and
then will flash slowly until the vehicle
is disarmed.
Engine Coolant Temperature Warning
Light
This warning light warns of an
overheated engine condition. If the
e n

gine 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
sound for four minutes or until the engine is
able to cool, whichever comes first.

If the light turns on while driving, safely pull over
a n

d stop the vehicle. If the Air Conditioning (A/C)
system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle.

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.

102 GETTING TO KNOW YOUR INSTRUMENT PANEL

If the temperature reading does not return to
normal, turn the engine off immediately and call
for service.

Refer to “If Your Engine Overheats” in “In Case
Of

Emergency” for further information.
Transmission Temperature Warning Light
— If Equipped
This warning light will illuminate to
warn of a high transmission fluid
te

mperature. 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 or NEUTRAL, until the
light turns off. Once the light turns off, you may
continue to drive normally.
Battery Charge Warning Light
This warning light will illuminate when
the battery is not charging properly. If
i t
stays on while the engine is running,
there may be a malfunction with the
charging system. Contact an authorized dealer
as soon as possible.
This indicates a possible problem with the
e l

ectrical system or a related component.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
li
ght turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer.
A chime will sound when this light turns on.
Do not operate the vehicle until the cause is
c o

rrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
Electronic Throttle Control (ETC) Warning
Light

This warning light will illuminate to
indicate a problem with the Electronic
T h

rottle Control (ETC) system. If a
problem is detected while the vehicle is
running, 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.

NOTE:
This light may turn on if the accelerator and
b r

ake pedals are pressed at the same time.
If the light continues to flash when the vehicle is
r u

nning, immediate service is required and you
may experience reduced performance, 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
ACC/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.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.

YELLOW WARNING LIGHTS
Engine Check/Malfunction Indicator
Warning Light (MIL)
The Engine Check/Malfunction
Indicator Light (MIL) is a part of an
On

board Diagnostic System called
OBD II that monitors engine and
automatic transmission control systems. This
warning 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
i g

nition switch from OFF to ON/RUN, have the
condition checked promptly. Certain conditions, such as a loose or missing
g
a

s cap, poor quality fuel, etc., may illuminate
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
t o

alert serious conditions that could lead to
immediate loss of power or severe catalytic
converter damage. The vehicle should be
serviced by an authorized dealer as soon as
possible if this occurs.
WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher
temperatures than in normal operating
conditions. 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
t h

e driver, occupants or others.

104 GETTING TO KNOW YOUR INSTRUMENT PANEL
Electronic Stability Control (ESC) Active
Warning Light — If Equipped

This warning light will indicate when the
Electronic Stability Control system is
Ac

tive. The “ESC Indicator Light” in the
instrument cluster will come on when the
ignition is placed in the ON/RUN or ACC/ON/RUN
position, 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 warning light remains on after several ignition
cycles, and the vehicle has been driven several
miles (kilometers) at speeds greater than 30 mph
( 4

8 km/h), see an authorized dealer as soon as
p o

ssible to have the problem diagnosed and
corrected.

The “ESC OFF Indicator Light” and the “ESC
Indicator Light” come on momentarily each
time the ignition is placed in the ON/RUN or
ACC/ON/RUN position.
The ESC system will make buzzing or clicking
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 warning light indicates the
Electronic Stability Control (ESC) is

Each time the ignition is turned to ON/RUN or
A C

C/ON/RUN, the ESC system will be on, even
if it was turned off previously.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that
t h

e 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
m
e

ntioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided),
sh
ould 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.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause damage
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.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair
kit and contact an authorized dealer as soon

108 GETTING TO KNOW YOUR INSTRUMENT PANEL
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
a
nd Maintenance (I/M), this check
v e

rifies 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.
Normally, the OBD II system will be ready. The
OB
D 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. Your vehicle has a simple ignition actuated test,
w
h

ich you can use prior to going to the test
station. To check if your vehicle's OBD II system
is ready, you must do the following:

1. Cycle the ignition switch to the ON position, b
ut do not crank or start the engine.

NOTE:
If you crank or start the engine, you will have to
s t

art this test over.
2. A s soon as you cycle the ignition switch to
t
he ON position, you will see the
“Malfunction Indicator Light (MIL)” symbol
come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two t
hings will happen:
The MIL will flash for about 10 seconds
and then return to being fully illuminated
until you turn OFF the ignition or start the
engine. This means that your vehicle's
OBD II system is not ready and you
should not proceed to the I/M station.
The MIL will not flash at all and will
remain fully illuminated until you place
the ignition in the off position or start the
engine. This means that your vehicle's
OBD II system is ready and you can
proceed to the I/M station.
If your OBD II system is not ready, y
ou should
see an authorized dealer or repair facility. If your
vehicle was recently serviced or had a battery
failure or replacement, you may need to do
nothing more than drive your vehicle as you
normally would in order for your OBD II system
to update. A recheck with the above test routine
may then indicate that the system is now ready.

Regardless of whether your vehicle's OBD II
s y

stem is ready or not, if the MIL is illuminated
during normal vehicle operation you should have
your vehicle serviced before going to the I/M
station. The I/M station can fail your vehicle
because the MIL is on with the engine running.
