Tachometer
When the gas engine is off and the key is in the
ON/RUN position, the position of the tachometer
indicator shows the state of the vehicle:
•AUTO STOP position indicates that the vehicle is
still able to move and the engine could restart,
by an Auto Start, at any time.
•OFF position indicates that the engine is off.
When the engine is on, the tachometer indicator shows
the engine’s revolutions per minute (rpm).
Charging System Light
This light will come on
briefly when the
ignition is turned to
ACC/ACCESSORY or
ON/RUN, but the engine is
not running, as a check
to show it is working.
It should go out once the engine has been started. If it
stays on, or comes on while driving, there could be
a problem with the charging system. A charging system
Driver Information Center (DIC) message may also
appear. SeeDIC Warnings and Messages on page 3-12
for more information. This light could indicate that
there are electrical problems. Have it checked right
away. If a short distance must be driven with the light
on, be certain to turn off all the accessories, such as the
radio and air conditioner. United States Version

If there is a problem with the battery charging system,
the DIC will display a message. SeeDIC Warnings
and Messages on page 3-12.

the owner manual for more information.
DIC Warnings and Messages
Warning messages are displayed on the DIC to notify
the driver that the status of the vehicle has changed and
that some action may be needed by the driver to
correct the condition. If there is more than one message
that needs to be displayed they will appear one after
another. Some messages may not require immediate
action but you should press the select button or the trip
odometer reset stem on the instrument panel cluster
to acknowledge that you received the message
and clear it from the display. Some messages cannot
be cleared from the display because they are more
