If the coolant level drops within a short time after replenishing

If you cannot find a leak, have your Lexus dealer test the cap and check for leaks in
the cooling systems.

The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing serious injuries, such as burns.

Be sure to wash it off with water to prevent damage to parts or paint.
