CRUISE CONTROL SYSTEM
B: CAUTION
•Before disassembling or reassembling parts, al-
ways disconnect the battery ground cable from bat-
tery. When repairing the audio, control module, etc.
which are provided with memory functions, record
the memory contents before disconnecting the
ground cable from battery. Otherwise, the memory
will be cleared.
•Reassemble the parts in the reverse order of dis-
assembly unless otherwise indicated.
•Adjust the parts to specifications specified in this
manual.
•Connect the connectors securely during reas-
sembly.
•After reassembly, ensure functional parts oper-
ate properly.
