DIC Warnings and
Messages (Base and
Uplevel Systems)
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.
Multiple messages may appear
one after another.
The DIC monitors some uid levels,
battery of the Remote Keyless Entry
(RKE) transmitter, the theft-deterrent
system on vehicles with this feature,
the brake light switch, and important
exterior lights, including wiring and
fuses.Some messages may not require
immediate action, but you can
acknowledge that you received the
messages and to clear them from the
display by doing one of the following:
Press the OK button on the base
level audio system.
Press the multifunction knob, if
your vehicle has this feature,
on the uplevel audio system.
Press the left thumbwheel, if your
vehicle has this feature, on the
steering wheel.
If there are several warning
messages, acknowledge them
one at a time.Some messages cannot be cleared
from the DIC display because they
are more urgent. These messages
require action before they can
be cleared. You should take any
messages that appear on the display
seriously and remember that clearing
the messages will only make the
messages disappear, not correct
the problem.
Warning messages for the uplevel
DIC follow. On the base level
DIC, messages appear in an
abbreviated form.
