Service & Appearance Care 
Fuels  in  Foreign  Countries 
If you  plan  on  driving  in  another  country  outside  the US. or Canada, 
unleaded  fuel  may  be hard 
to find. Do not use  leaded  gasoline.  If  you  use 
even  one  tank  full,  your  emission  controls  won’t  work  well  \
or  at  all.  With 
continuous  use,  spark  plugs  can  get  fouled,  the  exhaust  system \
 can  corrode, 
and  your  engine 
oil can  deteriorate  quickly.  Your  vehicle’s  three-way  catalytic 
converter  and  oxygen  sensor  will  be  damaged. 
All of  that  means  costly 
repairs  that  wouldn’t 
be covered  by your warranty. 
To check  on  fuel  availability,  ask an auto club, or contact a major oil 
company 
that does  business  in  the  country  where  you’ll  be  driving. 
You can also write us at the following  address  for  advice. Just tell  us  where 
you’re 
going and  give  your  Vehicle  Identification  Number (VIN).
