18. Seat Belt Reminder Light
This light will turn on for five to eight seconds as
a bulb check when the ignition switch is first
placed in the RUN position. A chime will sound if
the driver's seat belt is unbuckled during the bulb check.
The Seat Belt Reminder Light will flash or remain on
continuously if the driver's seat belt remains unbuckled
after the bulb check or when driving.
19. Vehicle Security Light — If Equipped
The Vehicle Security Light flashes rapidly
when the Vehicle Security Alarm is arming,
and slowly when the Vehicle Security Alarm is
armed.
20. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is placed in the RUN position.
21. Electronic Throttle Control (ETC) Light
This light will turn on briefly as a bulb check
when the ignition switch is placed in the RUN
position. This light will also turn on while the
engine is running if there is a problem with the
Electronic Throttle Control (ETC) system.
If the light comes on while the engine is running, safely
bring the vehicle to a complete stop as soon as possible,
place the shift lever in PARK, and cycle the ignition
through the ACC and RUN positions. The light should
turn off. If the light remains lit with the engine running,
your vehicle will usually be drivable. However, see an
authorized dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required. In this case, you may
experience reduced performance, an elevated/rough idle
or engine stall, and your vehicle may require towing.
