2.START ENGINE WITH INTELLIGENT KEY (IF EQUIPPED)
Check if the engine could be started by all registered Intelligent Keys.
The engine cannot be started by some Intelligent Keys>>Int elligent Key is low battery or malfunction. Refer
to BL-158, "
Intelligent Key Battery Replacement" .
The engine cannot be started by all Intelligent Keys >> GO TO 3
The engine can be started by all Intelligent Keys >> GO TO 4
3.CHECK “KEY” WARNING LAMP ILLUMINATION
When pushing the ignition switch, check if “KEY” warning lamp in combination meter illuminates.
KEY warning lamp illuminates green >> Refer to BL-119, "
Trouble Diagnosis Symptom Chart" .
KEY warning lamp illuminates red >> Refer to BL-119, "
Trouble Diagnosis Symptom Chart" .
Does not illuminate >> Refer to BL-119, "
