■
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 rec-
ognize him/her as a child depe nding on his/her physique and pos-
ture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a larger child who has outgrow n 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 pas-
senger seat. A forward-facing child restraint system should only
be installed on the front passenger seat when it is unavoidable.
(  P. 136)
*5: In case the indicator light is not illuminated, consult this manual on
how to install the child restraint system properly. ( P. 140)

CAUTION
■
Front passenger occupant cl assification system precautions
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG OFF” indicator is illuminated, ask the
passenger to sit up straight, well back in the seat, feet on the floor, and
with the seat belt worn correctly. If the “AIR BAG OFF” indicator still
remains illuminated, either ask the passenger to move to the rear seat, or
if that is not possible, move the front passenger seat fully rearward.
● When it is unavoidable to install a forward-facing child restraint system on
the front passenger seat, install the child restraint system on the front pas-
senger seat in the proper order. ( P. 140)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction of the
detection system. In this case, contact your Toyota dealer immediately.
● Child restraint systems installed on the second seat should not contact the
front seatbacks.
● Do not use a seat accessory, such as a cushion and seat cover, that cov-
ers the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.

■Downshift restriction warning buzzer (S mode in multi-mode type)
To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (A buzzer will sound twice.)

Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
