remain on briefly as a bulb check. If the light stays on or
turns on while driving, turn off some of the vehicle’s
non-essential electrical devices (i.e., radio) or slightly
increase engine speed (if at idle). If the light remains on,
it means that the charging system is experiencing a
problem. See your local authorized dealer to obtain
service immediately.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
7. Electronic Throttle Control (ETC) Warning Light
This light will turn on briefly as a bulb check
when the ignition switch is placed in the ON/
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 key.
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.
Also, have the system checked by an authorized dealer if
the light does not come on during starting.
8. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
