As long as the headlight are turned off, you do not have to disconnect the battery.
I found out, it's around 210F.
disconnect the wires that connect to the battery marked either in black and red or a - and +, then if there any clamps where the battery is sitting unscrew those as well. Then reverse order to put new battery in
There are quite a number of dashboard lights on Lexus ES300. The common ones include handbrake light, check engine, temperature, check oil, battery light and so many others.
You either have a battery that has a dead cell and needs replacing or something is on pulling power from the battery. Can be any light on the vehicle or a stuck relay. In rare instances a defective alternator can cause this.
The starter is located at the front right of the engine. It is located between the engine and battery. You can trace the thin cable that runs from the battery to the back of the starter to locate it.
Car alarm in Lexus ES300 started going off at random when car was parked, not running. I changed the key fob battery (flat watch battery) with a new battery and it fixed the problem.
I would unplug the battery. This will reset your clock, etc., but it should turn the light off.
Use your remote control to Unlock, Lock and Unlock again. It worked for my case very well.
Unfortunately, the 2002 es300 was the first year that Lexus did not use a IACV in the ES300.
The first thing to do when replacing a cigarette lighter on a 1995 Lexus ES300 is to remove the fuse for this from the fuse box and disconnect the battery. Then remove the clip on the back of the lighter and slide the metal part out the front. Insert the new metal liner and connect the rear clip. Place the fuse back in the fuse box and reconnect the battery.
