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

make the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.

(ABS) is adjusting brake pressure to help avoid a
braking skid.

stops adjusting brake pressure. SeeAntilock Brake
System (ABS) on page 4-5for more information.

the charge in the battery. Turn off unnecessary
accessories to allow the battery to recharge.
3-55
