CAUTION
■Front passenger occupant classification system precautions
●Do not apply a heavy load to the front passenger seat or equipment.
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback from the rear seat.
●Do not let a rear seat 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. 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, return the seatback to a position where it does
not touch the rear seat. 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 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 remains 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. 1 1 4 )
●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.
●Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
●Child restraint systems installed on the rear seat should not contact the front seat-
backs.

■Shift ranges and their functions
●You can choose from 8 levels (GS460) or 6 levels (GS350) of
engine braking force.
●A lower shift range will provide greater engine braking force than a
higher shift range, and the engine revolutions will also increase.
●If you accelerate while in ranges “1” to “7” (GS460) or “1” to “5”
(GS350), the shift range may automatically range up in accordance
with the vehicle’s speed.
●A higher shift range is automatically selected when the automatic
transmission fluid temperature is high.
■“S” mode
●When the shift range is “6” (GS460) or “4” (GS350) or lower, holding the shift
lever toward “+” sets the shift range to “8” (GS460) or “6” (GS350).
●To prevent the engine from over-revving, upshifting may automatically occur.
■Downshifting restrictions warning buzzer (in the “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. (The warning buzzer will sound twice.)
■When driving with the cruise control system (or dynamic radar cruise control sys-
tem)
The engine brake will not operate in the “S” mode, even when downshifting to “7”,
“6”, “5” or “4” (GS460) or “5” or “4” (GS350). (P. 167, 171)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP” switch is
turned to ACCESSORY or IGNITION ON mode after driving in snow mode.
■If the shift lever cannot be shifted from “P”

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 turn to IGNITION ON mode, this could mean that these sys-
tems 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 the indicated
vehicle’s systems. (P. 5 3 4 )
*: These lights turn on when the “ENGINE START STOP” switch is turned
to IGNITION ON mode to indicate that a system check is being per-
formed. They will turn off after the engine is on, or after a few seconds.
There may be a malfunction in a system if the lights do not come on, or
turn off. Have the vehicle inspected by your Lexus dealer.
