On-Vehicle Inspection

REMOVE COWL TOP VENTILATOR LOUVER RH (See REMOVAL )
DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.

NOTE: After the engine switch is turned off, the HDD navigation system requires approximately 6 minutes to record various types of memory and settings. As a result, after turning the engine switch off, wait 6 minutes or more before disconnecting the cable from the negative (-) battery terminal.
