                 2 .    Service Precaution on Model with Supplemental Restraint System
                     DANGER

                 Some vehicles are equipped with Supplemental Restraint System (SRS), i.e., driver
                 airbag. Failure to carry out service operations in the correct sequence may cause the
                 SRS to unexpectedly deploy during servicing, or even lead to critical accident.
                 Furthermore, an operational mistake may also prevent the SRS from normal operations.
                 Before servicing (including removal, installation, inspection or replacement of any
                 part), be sure to read through the following items carefully and perform the correct
                 procedures described in the service manual.

                 (a)    General Precaution
                        •     Since it is difficult to identify the failure of the SRS, Diagnostic Trouble Code
                              (DTC) is an essential source of information during troubleshooting.Thus, when
                              troubleshooting the SRS, always remember to check the DTCs before
                              disconnecting the battery.
                        •     Operation can only be started 90 seconds after the ignition switch is turned to
                              the “LOCK” position and the negative (-) cable and the positive (+) cable are
                              disconnected from the battery. (The SRS is equipped with backup power supply.
                              Therefore, if any operation is taken within 90 seconds after disconnecting the
                              battery negative (-) cable and positive (+) cable, the SRS may deploy suddenly.)
