1-7. Safety information
■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may recognize him/
her as a child depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a larger child who has outgrown a child restraint system sits in
the front passenger seat, the system may recognize him/her as an
adult depending on his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front passen-
ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. (P. 77)
*5: In case indicator is not illuminated, consult this manual as for installing
the child restraint system properly. (P. 8 0 )

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 Lexus dealer immediately if this occurs.
■Warning lights
Warning lights inform the driver of malfunctions in any of the vehi-
cle’s systems. (P. 3 3 9 )
*: These lights turn on when the engine switch is turned to IG-ON mode
to indicate that a system check is being performed. They will turn off
after the engine is started, or after a few seconds. There may be a mal-
function in a system if a light does not come on, or if the lights do not turn
off. Have the vehicle inspected by your Lexus dealer.
