2-3. Operating the lights and windshield wipers

■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.

■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.
