Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as the multiport fuel injection system/sequential multiport
fuel injection system, dynamic radar cruise control system, cruise control system,
anti-lock brake system, vehicle dynamics integrated management, SRS airbag sys-
tem and seat belt pretensioner system, be sure to check with your Lexus dealer for
precautionary measures or special instructions regarding installation.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.

■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 syst em (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”
