CAUTION
Always use a genuine Lexus fuse or equivalent for
replacement. Never install an ordinary wire Ð even for
a temporary fix. This may cause extensive damage and
possibly a fire.
ADDING WASHER FLUID
If the washer tank becomes nearly empty, add washer
fluid.
You may use plain water as washer fluid. However, in cold
areas where temperatures range below the freezing point, use
washer fluid containing antifreeze. This product is available at
your Lexus dealer and most auto parts stores. Follow the
manufacturer's directions for how much to mix with water.
