FUSE SERVICE WARNINGS

WARNINGFor vehicles with DSC, if the room fuse is disconnected, the stored initial position of the steering angle sensor will be cleared and the DSC will not operate properly, making the vehicle unsafe to drive. Perform the steering angle sensor initialization procedure after connecting the room fuse. (See STEERING ANGLE SENSOR INITIALIZATION PROCEDURE .)

FUSE SERVICE CAUTION

CAUTIONDetermine and correct the cause of the burnt fuse before replacing it. If the fuse is replaced before doing this, it may burn again.
