not come on when you start the hybrid system, this could mean that these
systems are not available to help protect you in an accident, which could
result in death or serious injury. Have the vehicle inspected by your Toyota
dealer immediately if this occurs.

vehicle’s systems. ( P. 426)

after the hybrid system is started is on, or after a few seconds. There
may be a malfunction in a system if the lights do not come on, or turn
off. Have the vehicle inspected by your Toyota dealer.
