ing from under the vehicle for several minutes. This is the sound of a fuel evaporation
leakage check and, it does not indicate a malfunction.
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are cur-
rently available in the market. You should kn ow that Toyota does not warrant these prod-
ucts and is not responsible fo r their performance, repair, or replacement, or for any

non-genuine Lexus products could affect its performance, safety or durability, and may
even violate governmental regulations. In addition, damage or performance problems
resulting from the modification may not be covered under warranty.
