CAUTION

If a safety system warning light does not come on
Should a safety system light such as the ABS and 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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional,
immediately if this occurs.
