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.

This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however, until the
battery is discharged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the nearest Lexus dealer or
