On a 2000 Lexus RX300, the number 1 cylinder is located at the front of the engine, which is a V6 configuration. It is positioned on the driver's side (left side when facing the engine) and is the first cylinder closest to the timing belt or chain. The cylinders are numbered from front to back, with the number 1 being the first on that side.
To change the low beam on a 2003 Lexus RX300, first, open the hood and locate the headlight assembly. Remove the cover or cap on the back of the assembly, then disconnect the electrical connector from the bulb. Twist the old bulb counterclockwise to remove it, then insert the new bulb by twisting it clockwise. Finally, reconnect the electrical connector and replace the cover.
To replace the headlights in a 2002 Lexus RX300, first, open the hood and locate the headlight assembly. Disconnect the power connector from the back of the headlight bulb and remove the rubber cover. Twist the bulb socket counterclockwise to release it, then pull out the old bulb and insert the new one, making sure not to touch the glass. Finally, reassemble by reversing the steps and test the new headlight.
To remove the front seat of a Lexus RX300, first, slide the seat all the way back to access the rear bolts. Use a socket wrench to remove the bolts securing the seat to the floor. Next, disconnect any electrical connectors for seat adjustments and airbags. Finally, slide the seat forward to access and remove the front bolts, then lift the seat out of the vehicle.
To reprogram a Lexus RX300 key fob, first, sit in the vehicle and close all doors. Insert the key into the ignition and turn it to the "ON" position without starting the engine, then turn it back to "OFF." Repeat this process twice, then turn the ignition back to "ON" a final time. Press and hold the "lock" button on the key fob for a few seconds, and this should reprogram the fob. If this doesn't work, consult the owner's manual or a professional locksmith for assistance.
I find that situation occurs with our RX300 when someone hits/bumps the turn signal switch arm. Often the "toggle" for the lights changes to the "off" position. It's somewhat frustrating when you turn the car on at night expecting the headlights to turn on automatically. All you need to do is turn it back to the "on" position.
