During recharging, the battery is producing hydrogen gas.
Therefore, before recharging:
1. Maintenance type batteries – Remove the vent plugs.
2. If recharging with the battery installed on the vehicle, be sure to disconnect the ground cable.
3. Make sure the power switch on the recharger is off when connecting the charger cables to the battery and when disconnecting them.
a. Look carefully at the fuse. If the thin wire is broken, the fuse has blown. If you are not sure or if it is too dark to see,
try replacing the suspected fuse with one of the same value that you know is good.
b. Only Install a fuse with the amperage rating designated on the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull out the “CIG,” “DOME” or “A.C” fuse, which may be
dispensable for normal driving, and use it if its amperage rating is the same.
If you cannot use one of the same amperage, use one lower than, but as close as possible to, the amperage. If the
amperage is lower than the specified, the fuse might blow out again but this does not indicate anything wrong. Be sure to get the correct fuse as soon as possible and return the substitute to its original clips.
It is a good idea to purchase a set of spare fuses and keep them in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem with the electrical system. Have your Lexus dealer correct it as soon as possible.
