To turn the lights on, twist the knob on the end of the lever.
FIRST CLICKST OP: Only the parking, tail, license plate, side
marker and instrument panel lights turn on.
SECOND CLICKSTOP: Headlights also turn on.
THIRD CLICKSTOP (”AUTO”): The headlights and all other
lights automatically turn on depending on the darkness of the
surroundings.*
NOTE:
*The operating condition or sensitivity can be changed.
Ask your Lexus dealer for details. Vehicles sold in U.S.A.: When the headlights are on, the
headlight indicator lights up in the instrument cluster.
Vehicles sold in Canada:
When the tail lights are on, the tail
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
to first or second clickstop.

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.

For high beam, push the lever forward. Pull it back for low

A blue light in the instrument cluster indicates high beam or
headlight flasher is on.
The headlight flasher works even when the headlight switch is
off.

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.

LIGHT SENSITIVE OPTITRONMETER
Light sensitive optitron meter reduces unwanted glare of
the instrument cluster to provide a fine view for the driver.
The meter is originally set to “AUTONorm” mode, so the
reflection of the instrument cluster is adjusted
automatically by tinting the cluster glass depending on
the lighting condition of your surroundings.
There are “AUTO” and “MANUAL” modes. To change the
mode as you like, follow the procedure below.
The reflection control switch is located in the switch box.

after the “MODE” switch is pushed. The mode shown last is
set.
The cluster glass may not be tinted in “MANUAL−1”,
“MANUAL−2” or “MANUAL− 3” mode in the night or cloudy dark

When the ambient temperature in the vehicle interior is low, it
may take time for the cluster glass to be tinted.

2. Set the driving pattern selector switch to the normal
position.
Your transmission has a driving pattern selector switch which
allows you to select power, normal or snow mode to suit your
driving condition. For ordinary driving, Lexus recommends
that you use the normal mode to improve fuel economy.
3. For more powerful acceleration and sporty driving, use
the power position.
In the power mode, the “ECT PWR” light in the instrument
cluster is on and the most suitable shift pattern is selected
depending on the driver’s operation of accelerator and brake
pedal and on the vehicle condition. See “Automatic shifting
point change control” on page 363.
For snow mode, see “Electronic Throttle Control System”
on page 371.
