Whenever small children are in the vehicle, lock the rear
door so that it does not open by the inside door handle.

THEFT DETERRENT SYSTEM
G11005
To deter theft of the vehicle, this system is designed to
sound an alarm if any of the doors, trunk or hood is
forcibly unlocked or opened, or the battery terminal is
disconnected and then reconnected while the vehicle is
locked.
The alarm blows the horn intermittently, flashes the headlights,
tail lights, turn signal lights and other exterior lights. When the
interior light switch is in the “DOOR” position, the interior lights
also turn on.
After the alarm is activated, when you unlock any door or the
trunk using a entry function, wireless remote control or
mechanical key, the tail lights turn on for about 2 seconds to
inform you that the system was activated.

FIRST CLICKST OP: Only the parking, tail, license plate, side

light indicator lights up in the instrument cluster.
With the knob in the “AUTO” position, there may be a case
that the headlights do not turn on immediately, even when
the vehicle enters a dark place such as a tunnel or parking
lot according to lighting conditions. In this case, we
recommend you to twist the knob manually to the second
clickstop to turn on the headlights immediately.
When the headlight switch is turned to the first or second
clickstop, the brightness of the instrument cluster will be
reduced slightly unless the maximum brightness is provided by
pushing the “MAX” button.
However, the brightness of the instrument cluster will not be
reduced in daytime even when the headlight switch is turned

The automatic light control sensor is on top center of the
instrument panel.
Do not place anything on the instrument panel, and/or do not
affix anything on the windshield to block this sensor.
When the headlights come on, the lights automatically turn off
about 30 seconds after any of the doors is opened and closed
with the engine switch off.* To turn them on again, select the
engine switch in “IG− ON” mode, or turn the headlight switch off
and then twist the knob until the first or second clickstop.
If you are going to park for over one week, make sure the
headlight switch is off.
When the headlight switch is on with all the doors locked and
the trunk closed, pushing the ”LOCK” button on the electronic
key turns off the headlights.
NOTE:
*The time before turning off the lights can be changed.
Ask your Lexus dealer for details. Daytime Running Light System
The headlights turn on at reduced intensity when the parking
brake is released with the engine started, even with the light
switch in the ”OFF” position. They will not
go off until the engine
switch is turned off.
To turn on the other exterior lights and instrument panel lights,
twist the knob to the first clickstop.
Twist the knob to the second clickstop to turn on the headlights
to full intensity for driving at night.
When setting the knob to the third clickstop (”AUTO”), the
headlights will automatic ally adjust to full intensity and/or turn
on the other lights depending on the darkness of the
surroundings. Likewise, as the surroundings become brighter,
the headlights will turn to reduced intensity, ultimately turning
off the other lights.
NOTICE
To prevent the battery from being discharged, do not
leave the lights on longer than necessary when the
engine is not running.

Automatic headlight leveling system
The headlight beam level is always maintained automatically
at the proper level in all loading conditions so that your
headlights do not dazzle other road users.
If there is a problem somewhere in this system, the message
“CHECK HEADLIGHT” appears on the multi−information
display. At this time, the master warning light comes on and a
warning tone sounds. If the warning message appears, have
your vehicle checked by your Lexus dealer as soon as
possible.
Adaptive Front Lighting System (AFS)
Adaptive Front Lighting System (AFS) provides the proper
headlight beam level according to the current driving
conditions. T his system moves the headlight beam left or right
according to the turning angle of the tires. The synergy of this
system and the automatic headlight leveling system improves
visibility at the intersections and curves.
The system operates when the vehicle speed increases above
10 km/h (6 mph), and stops when the vehicle speed drops
below 10 km/h (6 mph).
The system can operate within the limited range of the tires
turning angle. If you do not want to activate the system, you can cancel
the system.
Adaptive Front Lighting System cancel switch is located in the
switch box.
G12017
Push the button to use the switch box. To cancel the
system, push the “AFS OFF” switch. To turn it on, push
it again.
When the system is canceled, the “AFS OFF” indicator lights
up in the instrument cluster.
If the system fails, the indicator light in the instrument cluster
will flash. If this occurs, have your vehicle checked by your
Lexus dealer.
After operation, be sure to close the switch box to its original
position.

G12005
For signaling turns, move the lever up or down in the
conventional manner.
The engine switch must be selected in “IG−ON” mode.
The turn signal is self −cancelling after a turn, but after a lane
change, you may have to cancel it by hand. You can also signal
a lane change by moving the turn signal lever partway and
holding it there.
If the green light in the instrument cluster flashes faster than
normal, it indicates that the front or rear turn signal bulb has
burned out. If this indicator light does not come on, the fuse
or the indicator light itself has probably failed.
FOG LIGHT SWITCH
G12006
To turn on the fog lights, twist the band of the headlight
lever to the fog light mark. They will come on only when
the headlights are on low beam.
When the fog lights are on, the indicator lights up in the
instrument cluster.

CAUTION
Be careful not to get your fingers caught between the
wipers and windshield.
When the wiper lever is in the “AUTO” position with the
engine switch on, the wipers could operate
automatically in the following cases:
 If you touch the upper center of the windshield
adjacent to the sensor.
 If you wipe the upper center of the windshield
(adjacent to which the sensor is located) with a towel.
 If the windshield vibrates.
 If you touch the sensor.
For mist wiper operations (a single wipe), pull the lever up
and release it.
To make the washer squirt, pull the lever toward you and
release it.
If the wiper lever is in the “OFF” position, the wipers will
automatically make 3 wipes and then a single wipe later to
sweep the windshield completely.* The interval between the
3 wipes and the last wipe will depend on the vehicle speed.
The last sweep does not happen if the vehicle speed exceeds
about 170 km/h (106 mph).
NOTE:
*This function can be changed as follows: The time before the last single wipe can be set for
about 3 seconds.
 The last single wipe can be deactivated.
Ask your Lexus dealer for details.
The warning message “LOW WASHER FLUID” is displayed in
the multi−information display when the fluid level in the tank
becomes very low. For information on adding washer fluid, see
“Adding washer fluid” on page 589.
When the headlights are on and the washers are activated by
pushing the windshield washer switch, the headlight cleaner
operates once automatically.
In cold weather, warm the windshield with the defroster before
using the washer. This will help prevent icing, which could
block your vision.
The rear window and outside rear view mirror defogger
automatically turns on when you operate the wipers.
