The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
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 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 checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately 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 brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.

Red TelltaleLight What It Means
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 engine is running, the light will either stay on or flash de-
pending on the nature of the problem. Cycle the ignition key 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 engine running, your vehicle will usually be driv-
able; however, see an authorized dealer for service as soon as possible.
If the light continues to flash when the engine is running, 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 first turned to ON/
RUN 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.

Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator 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 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 illuminate
the light after engine start. The vehicle should be serviced if the light stays on through sev-
eral 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 ser-
viced as soon as possible if this occurs.

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 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 ve-
hicle 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 momentarily 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.
