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 ºOFFº 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 (ºAUTOº), 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 theengine is not running.
Automatic headlight leveling system
SV12022
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 this system fails, the warning light in the instrument cluster
comes on. If this occurs, have your vehicle checked by Lexus
dealer.

ODOMETER AND TRIP METER
SV13015
This meter displays the odometer and two trip meters. To
change the mode indication, push the ºODO/TRIPº knob
briefly. Each time you push the knob, the mode changes
in order from the odometer to trip meter A to trip meter B,
then back to the odometer, etc.
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 set A trip meter to zero, display the A meter reading,
push the knob and hold it. The same applies for the B trip
meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.
