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 hybrid system, multiport fuel injection system/
sequential multiport fuel injection system, dynamic radar cruise control system,
cruise control system, anti-lock brake system, vehicle dynamics integrated manage-
ment, SRS airbag system and seat belt pretensioner system, be sure to check with
your Lexus dealer for precautionary measures or special instructions regarding
installation.
High voltage parts and cables on the hybrid vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.
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.

■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 “5” or
“4”. (→P. 1 8 3 )
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the “POWER” switch is turned to
ACCESSORY or ON mode after driving in snow mode.
■If the shift lever cannot be shifted from “P”
→P. 5 4 8
■If the indicator does not come on even after shifting the shift lever to “S”
This may indicate a malfunction in the transmission. Have the vehicle inspected by
your Lexus dealer immediately.
(In this situation, the vehicle will operate as if the shift lever is in “D”.)
■When in heavy traffic
To avoid running the hybrid battery (traction battery) down, leave the shift lever in
“D” or “S”.
