The automatic light control sensor is on the 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 you turn on the headlights, the lights automatically turn
off about 30 seconds after any of the doors is opened and
closed with the ignition switch turned to the “ACC” or “LOCK”\
position.* To turn them on again, turn the ignition switch to the
“ON” position, 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 wireless
remote control 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
ignition 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.

ODOMETER AND TRIP METER
13L145
This meter displays the odometer and two trip meters. To
change the mode indication, push the “ODO/TRIP” button
briefly. Each time you push the button, the mode changes
in order from the odometer to trip meter A to trip meter B,
then to the odometer.
The odometer records the total distance the vehicle has
been driven. The twin trip meter records two different
distances independently.
For example, you can use one meter to calculate the fuel
economy and the other to measure the distance on each trip.
To change the trip meter indication from one trip to the
other, push the “ODO/TRIP” button. To set the trip meter
A to zero, display the meter A reading, then push the
“RESET” button. The same applies for the trip B meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

accelerator pedal more firmly and slowly, you can drive your
vehicle at low speeds. Have your Lexus checked by your
Lexus dealer as soon as possible.

until the engine is stopped and the ignition switch is
turned to “ACC” or “LOCK” position.
Emissions inspection and maintenance (I/M) programs
Your vehicle may not pass a state emission inspection if the
malfunction indicator lamp remains on. Contact your Lexus
dealer to check your vehicle’s emission control system and
OBD (On −Board Diagnostics) system before taking your
vehicle for the inspection.
For details, see “Emissions inspection and maintenance (I/M)
programs” on page 431.
(g) Master Warning Light
If any system malfunctions, this warning light comes on or
flashes together with a warning tone, and a warning message
appears in the multi−information display. When the cause of
the problem is eliminated, the warning tone and message on
the display will turn off.
(h) “ABS” Warning Light
The light comes on when the ignition switch is turned to the
“ON” position. If the anti−lock brake system and the brake
assist system work properly, the light turns off after a few
seconds. Thereafter, if either of the systems malfunctions, the
light comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti −lock brake system, the brake
assist system, the traction control system and/or the vehicle
stability control system do/does not operate, but the brake
system still operates conventionally.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti− lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.
