How to Set the Timer for Headlamps on a Lexus

The headlamps on your Lexus are programmed to stay on after you have exited your vehicle. This is beneficial if it is dark and you need the light from your headlamps to walk up to your house or into a public place. The default time for the headlamps to remain on is 30 seconds. You can change this value to be longer, or you can adjust it so that your headlamps do not stay on at all when turn off the engine. You will need a special diagnostic tester to perform these steps.

Instructions

1

Put the key into the ignition and turn it to the "On" position.

2

Connect the Lexus diagnostic tester to the DLC3 port on the vehicle. The DLC3 port is located on the lower left side panel and is clearly labeled.

3

Turn on the diagnostic tester and select the "Customize" option.

4

Select "Verify Connections," press the "Yes" button, and press "Enter."

5

Select function "08" which is "Light Control."

6

Go to "Light Off Delay" and set it to your desired value. You can either choose 30 seconds, 60 seconds, 90 seconds or immediate off.
