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.

bubble of the gauge should not deviate from the center of the
gauge by more than four marks to either side of the gauge.2. Look at the beam angle gauge (horizontal movement). The
red mark should not deviate by more than one mark to either
side of the gauge.
If the error is over the value specified above, take the vehicle
