CAUTION
■
If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning light
not come on when you start the engine, 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.

lights turn on automatically whenever the engine is started and the park-
ing brake is released. Daytime running lights are not designed for use at
night.
Type A: Daytime running lights can be turned off by operating the switch.
