KEYS AND DOORS
16
If you do not drive your vehicle, store the electronic
key, keeping it at least 5 m (15 ft.) away from the
vehicle.
ALARMS AND WARNING MESSAGES
Your Lexus is equipped with alarms inside and outside, as
well as warning messages in the multiinformation
display, that remind you if there is a problem involving the
entry function.
Cases which are expected to happen frequently are
shown in the illustrations and the other cases are
described in the table. If an alarm or warning message
comes on, check to see what the problem is referring to
the illustrations and table, and take the appropriate
measure.
If a warning message appears, the master warning light
will blink.

SWITCHES

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.

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.

the headlights, push the switch with the headlights on.
The engine switch must be selected in “IG−ON” mode.
The warning message “LOW WASHER FLUID” is displayed in

becomes very low. For information on adding washer fluid, see
“Adding washer fluid” on page 589.
After operation, be sure to close the switch box to its original
position.
CAUTION
To reduce the chance of injury in case of an accident or
a sudden stop, keep the switch box closed when not in
use while driving.
NOTICE
Do not turn the headlight cleaner on with the washer
fluid tank empty. It may cause the cleaner motor to
overheat.
