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 , cruise control system, vehicle dynamics 
integrated management, SRS airbag system  and seat belt pretensioner system, be 
sure to check with your Lexus dealer for precautionary measures or special instruc-
tions regarding installation.
High voltage parts and cables on the hybr id 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 deal er before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.d tsc.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.

■Operation signals
●Doors: A buzzer sounds and the emergency flashers flash to indicate that the 
doors have been locked/unlocked. (Locked: Once; Unlocked: Twice)
●Windows and moon roof: A buzzer sounds when the windows and moon roof 
begin to close.
■Door lock buzzer
If a door is not fully closed, a buzzer sounds continuously if an attempt to lock the 
door is made. Fully close the door to stop the buzzer, and lock the vehicle once 
more.
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between key and vehicle may be affected, 
preventing the smart access system with  push-button start and wireless remote 
control from operating properly. (Way of coping: P.  5 3 1 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, 
airport or other facility that generates  strong radio waves or electrical noise
●When carrying a portable radio, cellular  phone, cordless phone or other wire-
less communication devices
●When the electronic key has come into contact with, or is covered by a metallic 
object
●When multiple electronic keys are in the vicinity
●When carrying or using the electronic key together with the following devices 
that emit radio waves
• Another vehicle’s electronic key
• A wireless key that emits radio waves
• Personal computer
●If window tint with a metallic content or  metallic objects are attached to the rear 
window

will be locked again and the alarm will automatically be set.
In case that the alarm is triggered, immediately stop the alarm. ( P.  9 0 )
■Battery-saving function
In the following circumstances, the entry func tion is disabled in order to prevent the 
vehicle and electronic key batteries from discharging. 
●When the entry function has not been used for 2 months or more
●When the electronic key has been left within approximately 3 ft. (1 m) of the 
vehicle for 10 minutes or more
The system will resume operation when... 
●The vehicle is locked using  the door handle lock switch
●The vehicle is locked/unlocked using the wireless remote control function  
(  P. 47) or the mechanical key ( P.  5 3 1 )
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The battery becomes depleted even if 
the electronic key is not used.) If the smart access system with push-button start 
or the wireless remote control function  does not operate, or the detection area 
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. (  P.  4 5 4 )
