CAUTION
■Front passenger occupant classification system precautions
●If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
minated. 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 cor-
rectly. If the “AIR BAG OFF” indicator still remain illuminated, either ask the pas-
senger 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 passenger seat
in the proper order. (→P. 151)
●Do not modify or remove the front seat.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction in the detection sys-
tem. In this case, contact your Lexus 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 covers the
seat cushion surface.
●Do not modify or replace the upholstery of the front seat.

2-1. Driving procedures
GX460_U.S.A. (OM60J00U)
■S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift
range to 6.
■AI-SHIFT
AI-SHIFT automatically selects the optimal gear according to driver performance
and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position. (Shifting
the shift lever to the S position cancels the function.)
The engine speed remain high after releasing the accelerator pedal. This does not
indicate a malfunction.
■When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( → P. 246, 250)
■If the shift lever cannot be shifted from P
→ P. 7 3 7
■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 Lexus dealer immediately.
(In this situation, the transmission will operate in the same manner as when the shift
lever is in D.)
■Downshift restriction warning buzzer (S mode)
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever is operated. (A buzzer will sound twice.)
