SWITCHES
23 Daytime Running Light System (Canada only)
The headlights turn on 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 ignition switch is turned off.
To turn on the other exterior lights and instrument panel lights, twist
the knob to the first clickstop.
Under the daytime running light system, the headlights turn on at
reduced intensity. Twist the knob to the second clickstop to turn to
full intensity for driving at night.
When setting the knob to the third clickstop (”AUTO”), the
headlights will automatically 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 (Vehicles with
discharge headlight only)
As the headlight beam level is always maintained automatically at
the proper level in all loading conditions, your headlights do not
dazzle other road users.
If this system fails, the multi information display shows a message
”HEADLIGHT LEVELING”. If this occurs, have your vehicle
checked by Lexus dealer.

For signaling turns, move the lever up or down in the
conventional manner.

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.
