See Filling the Tank on page 9‑45. Notice: Some additives are not compatible with E85 fuel and can harm the vehicle's fuel system. Do not add anything to E85. Damage caused by additives would not be covered by the vehicle warranty. Notice: This vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty. 9-45 Filling the Tank WARNING (CONTINUED) . { WARNING Fuel vapors and fuel fires burn violently and can cause injury or death. .
