[Warning] This vehicle is equipped with air bag. Before checking the engine compartment, read servicemanual first. Faultuy check and service can cause SRS air bag deployment and system defects that can be led to severe damage. E. Battery Cable
[Warning]
Before disconnecting the battery power, read service manual first.

8B-22 SUPPLEMENTAL RESTRAINT SYSTEM(SRS)GENERAL DESCRIPTION
AND SYSTEM OPERATION
INTRODUCTION SRS (Supplemental Restraint System) air bag protects driver and passenger by inflating air bag under collision and seat belt pre - tensioner is a supplemental equipment for seat belt
reducing shocks from the collision by pulling passenger’ s bodyagainst seat back at the same time of air bag inflation. Air bag unit has diagnosis functions and indicates system malfunctions to the driver by turning on the air bag warninglamp. CAUTION Perform the service procedures for the air bag system as ordered, if not, the air bag can be operated suddenly and it
could result in damage of air bag or injury. Before service(removal, installation, checking and replacement of parts),
observe the following instructions and service correctly.
1. To service, turn the ignition switch to ‘LOCK’ position and disconnect the negative battery cable and continue the procedures after approx. 30 seconds.
2. If the vehicle is damaged due to accident, remove the air bag ECU first to get the accident records.
3. Never use the other vehicle’s air bag parts and replace with genuine part, if required.
4. Do not disassemble or repair the air bag module, air bag unit and wiring harness to reuse.
5. Replace the air bag unit or air bag module if dropped, cracked or damaged.
