If the coolant level drops within a short time after replenishing

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

condition, have your vehicle checked by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
CAUTION

Do not touch the radiator or condenser as they may be hot and cause serious inju-
ries, such as burns.
