CAUTION:
All SRS wire harnesses are covered with yellow insulation. Before you disconnect any part of an SRS wire harness, disconnect the airbag connectors.
Whenever the ignition switch is ON, or has been turned OFF for less than three minutes, be careful not to bump the SRS unit: the airbags could
accidentally deploy and cause damage or injuries.
For additional precautions, refer to AIR BAGS AND SEAT BELTS / SERVICE PRECAUTIONS. See: Restraint Systems/Service Precautions
NOTE: The original radio has a coded theft protection circuit. Be sure to get the customer's code number before:
-
disconnecting the battery.
-
removing the No. 32 (7.5 A) fuse from the underhood fuse/relay box.
-
removing the radio.
After service, reconnect power to the radio and turn it ON. When the word "CODE" is displayed, enter the customer's 5-digit code to restore radio
operation.
1. When the engine is cool, drain the engine coolant from the radiator.
WARNING: Do not remove the radiator cap when the engine is hot; the engine coolant is under pressure and could severely scald you.
