Question about 2005 Lexus RX330

Open Question

What does it mean that AFS light is on? Might it have something to do with a slow leak in the electrical system? The car battery (have had 4 in 5 years) dies about 3 times per year but runs again after jump-start. I turned off interior lights years ago and turn off radio each time I park car.

Most likely right.... if the alternator quits you can often run off the battery but once you start accessories like wipers . heater etc it will not last long

you need a scan tool to clear the fault code before the light will go out, but a health check should be performed to see if any other problems exist.

SOURCE: Vehicle was parked and not started for 2 months.

Hi, there will be diodes in the generator that are letting the power from the battery drain away through the parked times when not in use. to prove it charge the battery- then disconnect the negative terminal on the battery, connect 24 hours later and see if the battery as kept it charge, if so - fit new alternator, good luck.

Afs mean lexus


Switch labelled 'AFS OFF' is down near the fuel door release.'AFS' means Adaptive Front lighting System (at night with the Bi-Xenon headlights) it swivels either side, pressing that button means they stay pointing straight ahead and don't turn when you turn the steering wheel. You need to push the button again to turn the AFS back on.

What does AFS of mean???? This is a indicator light on the dash.


Adaptive Front lighting System (AFS) is used when for example if it was day time and you entered a dark parking garage the lights would detect and adapt to the lighting environment which will then automatically trigger the Bi-xenon headlights to turn on themselves in order to illuminate the road ahead when the vehicle anticipates it is necessary. It is an automatic feature which turns on by itself for your convenience therefore you wont have to induce any actions, the car does it all for you. And most Importantly (I quote) "the Adaptive Front lighting System (AFS) automatically controls the headlight lighting pattern according to steering angle and vehicle speed to help provide better visibility at night."

'AFS off' light on dash what does it mean and how do


Hi there,

This is a possible sensor malfunction - related to Suspension Height circuit.

Whenever a warning light of this nature is displayed, your vehicle's onboard diagnostic OBDII will have store the appropriate Trouble Codes.

Your local Lexus Dealership will be able to connect their handheld scanner to your vehicle's computer, which will then tell them where the problem lies (this would take less than 30mins to diagnose - marvellous machines they are!)

Lexus will then direct you on the appropriate action.

Cheers,

How to replace Lexus RX330 headlights.


replacing the headlights is easy. There is no need to adjust the afs, is is automatically done within the vehicle. Changing the bulbs doesn't affect the afs system at all.
