Installation of a mobile two-way radio system
The installation of a mobile two-way radio system in your vehicle could affect elec-
tronic systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
●Cruise control system
●Dynamic radar cruise control system
●Anti-lock brake system
●SRS airbag system
●Seat belt pretensioner system
Be sure to check with your Lexus dealer for precautionary measures or special
instructions regarding installation of a mobile two-way radio system.
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.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.

1-2. Opening, closing and locking the doors and trunk
■Battery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
vehicle and electronic key batteries from discharging.
●When the entry function has not been used for a month 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 th e door handle lock switch.
●The vehicle is locked/unlocked using the wireless remote control function.
( P. 44)
●The vehicle is locked/unlocked using the mechanical key. ( P. 5 3 3 )
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year
and a half.)
●If the battery becomes low, an alarm will sound in the cabin when the engine
stops. ( P. 5 1 4 )
●The battery becomes depleted even if the electronic key is not used because
the key always receives radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. (  P. 4 5 6 )

the following electrical appliances that produce a magnetic field.

●If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by the
entry function. (Use the wireless re mote control to unlock the doors.)
●A sudden approach to the effective range or door handle operation may prevent
the doors from being unlocked. In this case, return the door handle to the original
position and check that the doors unlock before pulling the door handle again.
■When the vehicle is not driven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m) of
the vehicle.
■Security feature
If a door is not opened within approx imately 60 seconds after the vehicle is
unlocked, the anti-theft system automatically locks the vehicle again.
■Alarms and warning indicators
A combination of exterior and interior alarms as well as warnings displayed on the
multi-information display are used to prevent theft of the vehicle and unforeseeable
accidents resulting from erroneous operation. Take appropriate measures in
response to any warning indications on the multi-information display. ( P. 5 0 4 )
