■Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key
battery and the vehicle battery from being discharged while the vehicle is not in
operation for a long time.
●In the following situations, the smart access system with push-button start may
take some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of theoutside of the vehicle for 10 minutes or longer.
• The smart access system with push-button start has not been used for 5 days
or longer.
●If the smart access system with push-button start has not been used for 14 days
or longer, the doors cannot be unlocked at any doors except the driver’s door.
In this case, take hold of the driver’s door handle, or use the wireless remote
control or the mechanical key, to unlock the doors.
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between electronic key and the vehicle may
be affected, preventing the smart access system with push-button start and wireless
remote control from operatin g properly. (Way of coping: →P. 7 3 9 )

■Note for the unlocking function
●Gripping the door handle when wearing a glove may not unlock the door.
●A sudden approach to the effective range or door handle 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.
●If there is another electronic key in the detection area, it may take slightly longer
to unlock the doors after the door handle is gripped.
■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.
●The smart access system with push-button start can be deactivated in advance.

■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get the
electronic key too close to the vehicle when operating the system from the outside
of the vehicle.
Depending on the position and holding condition of the electronic key, the key may
not be detected correctly and the system may not operate properly. (The alarm may
go off accidentally, or the door lock prevention may not function.)

■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin when the engine
stops. (→P. 3 4 )
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indicate
that the electronic key battery may be depleted. Replace the battery when nec-
essary. ( →P. 6 4 4 )
• The smart access system with push-button start or the wireless remote con- trol does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Glass top ranges
•Table lamps

■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on auto-
matically (at a reduced intensity) whenever the engine is started and the parking
brake is released. Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help fuel economy.
■Headlight control sensor
■Automatic light off system
●When only the tail lights come on: The parking/front side marker, tail, license
plate and fog lights turn off if the “ENGINE START STOP” switch is turned to
ACCESSORY mode or turned off and the driver’s door is opened.
●When the headlights come on: The headlights, parking/front side marker, tail,
license plate and fog lights turn off 30 seconds after a door or the glass hatch is
opened and closed. (The lights turn off immediately if on the key is
pressed after all the doors are locked.)
To turn the lights on again, turn the “ENGINE START STOP” switch to IGNITION
ON mode, or turn the light switch off once and then back to
or .
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

3-1. Using the air conditioning system and defogger
GX460_U.S.A. (OM60J00U)Rear outlets (vehicles without a re
ar automatic air conditioning sys-
tem)
Direct air flow to the left or right,
up or down.
Turn the knob to open or close
the vent.
■Air conditioning system settings
When the “ENGINE START STOP” switch is turned on, the air conditioning system
settings will be set to those that were in use the last time the “ENGINE START
STOP” switch was turned off.
Air conditioning system settings are memorized individually on each electronic key,
so the settings reproduced will be specific to the key that is used.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and ambi-
ent conditions. As a result, the following may occur.
●Immediately after the switch is pressed, the fan may stop for a while until warm
or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.

4-3. Do-it-yourself maintenance
GX460_U.S.A. (OM60J00U)
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
●If recharging with the battery installed on the vehicle, be sure to disconnect the
ground cable.
●Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the battery.
■After recharging/reconnecting the battery
●Unlocking the doors using the smart key system may not be possible immedi-
ately after reconnecting the battery. If this happens, use the wireless remote
control or the mechanical key to lock/unlock the doors.
●Start the engine with the “ENGINE START STOP” switch in ACCESSORY
mode. The engine may not start with the “ENGINE START STOP” switch
turned OFF. However, the engine will operate normally from the second
attempt.
●The “ENGINE START STOP” switch mode is recorded by the vehicle. If the bat-
tery is reconnected, the vehicle will return the “ENGINE START STOP” switch
mode to the status it was in before the battery was disconnected. Make sure to
turn off the engine before disconnect the battery. Take extra care when con-
necting the battery if the “ENGINE START STOP” switch mode prior to dis-
charge is unknown.
If the system will not start even after multiple attempts, contact your Lexus dealer.
