CAUTION
■
Front passenger occupant cl assification system precautions
● Double Cab and CrewMax models: Do not let a rear passenger lift the
front passenger seat with their feet or press on the seatback with their
legs.
● Do not put objects under the front passenger seat.
● Do not recline the front passenger seatback so far that it touches a rear
seat or a back wall. This may cause the AIR BAG OFF indicator light to be
illuminated, which indicates that the passenger’s airbags will not deploy in
the event of a severe accident. If the seatback touches the rear seat or
back wall, return the seatback to a position where it does not touch the
rear seat or back wall. Keep the front passenger seatback as upright as
possible when the vehicle is moving. Reclining the seatback excessively
may lessen the effectiveness of the seat belt system.
● If an adult sits in the right 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 right front passenger seat fully rearward.
● When it is unavoidable to install the forward-facing child restraint system
on the front passenger seat, install the child restraint system on the front
passenger seat in the proper order. ( P. 144)
● 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.
● Double Cab and CrewMax models: Child restraint systems installed on the
rear seat should not contact the front seatbacks.
● Do not use a seat accessory, such as a cushion or seat cover, that covers
the seat cushion surface.
● Do not attach a commercial seatback table or other heavy item to the back
of the front passenger seat.
● Do not modify or replace the upholstery of the front seat.

Gear range display when driving in S mode
The current gear range is displayed on the combination meter. ( P. 182)
■ When driving with the cruise control system (if equipped)
The engine brake will not operate in the S mode, even when downshifting to
5 or 4 (6-speed models) or 4 or 3 (5-speed models). ( P. 223)
■ If the shift lever cannot be shifted from P
P. 643
■ If the S indicator does not come on even after shifting the shift lever to
S
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer, immediately.
(In this situation, the vehicle will operate as if the shift lever is in D.)
■ AI-SHIFT
The AI-SHIFT automatically shifts the gear to the optimal position according
to the driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D posi-
tion. (Shifting the shift lever to the S position cancels the function.)
The engine speed may remain high after releasing the accelerator pedal.
This does not indicate a malfunction.
■ Downshifting restrictions wa rning buzzer (in the S mode)
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. (The warning buzzer will
sound twice.)
