■If a safety system warning light does not come on
Should a safety system light such as the ABS/Multi Terrain ABS and SRS 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 seri-
ous injury. Have the vehicle inspected by your Lexus dealer immediately if this
occurs.
