FIRST CLICKSTOP: Only the parking, tail, license plate, side

SECOND CLICKSTOP: Headlights also turn on.
THIRD CLICKSTOP (ªAUTOº): The headlights and all other

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

With the knob in the ªAUTOº position, there may be a case
that the headlig hts 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 instrument panel light control dial
is turned fully up.
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.

ignition key turned to the ªACCº or ªLOCKº position.* If you
want to turn off the lights immediately, push the ªLOCKº button
on the wireless remote control key twice. The lights also can
be turned off immediately by pushing the ªLOCKº button on the
wireless remote control key with all the doors locked.
NOTE:* The time before turning off the lights can be changed.Ask your Lexus dealer for details.
If any of the side door is kept opened, the lights automatically
turn off after 30 minutes.

For high beam, push the lever forward. Pull it back for low
beam. For the headlight flasher, pull it further back.
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

For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the ªONº position.
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.

interval between sweeps, and downward to decrease
it.
The wiper lever must be in the ªINTº position.
The time interval between sweeps is shortened when the
vehicle speed increases. When the vehicle speed reaches
more than about 20 km/h (12 mph) with the interval adjuster in
the full upward position, the time interval becomes the shortest
1.5 seconds.
If you stop the vehicle with the wiper switch in the ªLOº position,
the wiper speed automatically changes from low speed to

If the wiper lever is in the ªOFFº 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: * The last single wipe can be deactivated. Ask your Lexus dealer for details.
The low washer fluid warning light in the instrument cluster
comes on when the fluid level in the tank becomes nearly
empty. For information on adding washer fluid, see ªAdding
washer fluidº on page 618.
