Adding Equipment to the Outside of

performance. Check with your dealer before adding
equipment to the outside of the vehicle.

Fuel

Use of the recommended fuel is an important part
of the proper maintenance of this vehicle. To help
keep the engine clean and maintain optimum vehicle
performance, we recommend the use of gasoline
advertised as TOP TIER Detergent Gasoline.
Look for the TOP TIER label on the fuel pump to
ensure gasoline meets enhanced detergency standards
developed by auto companies. A list of marketers
providing TOP TIER Detergent Gasoline can be found
at www.toptiergas.com.
