WARNING

  • Gasoline is extremely flammable and highly explosive under certain conditions.
  • Improper handling may result in burns or serious personal injury. Always stop the engine and do not smoke or allow open flames or sparks near the Nissan Sentra while refueling.

  • Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically.
  • Continuing to refuel may cause fuel overflow, fuel spray, and a potential fire hazard.

  • Use only an original equipment type fuel-filler cap.
  • The correct cap includes a built-in safety valve required for proper fuel system and emission control operation. Using an incorrect cap may cause system malfunctions, personal injury, or trigger the Malfunction Indicator Light (MIL).

  • Never pour fuel into the throttle body in an attempt to start the vehicle.
  • Do not fill a portable fuel container inside the vehicle or trailer.
    • Static electricity may cause an explosion of flammable liquid, vapor, or gas.
    • Always place portable fuel containers on the ground when filling.
    • Do not use electronic devices during refueling.
    • Keep the pump nozzle in contact with the container while filling.
    • Use only approved portable fuel containers for flammable liquids.

CAUTION

  • Do not use E-15 or E-85 fuel in the Nissan Sentra.
  • The LOOSE FUEL CAP warning message will appear if the fuel-filler cap is not properly tightened.
  • It may take several driving trips for the message to display. Failure to secure the fuel-filler cap after the warning appears may cause the Malfunction Indicator Light (MIL) to illuminate.

  • If the fuel-filler cap is loose or missing, the Malfunction Indicator Light (MIL) may illuminate.
  • If the light turns on due to a loose or missing cap, tighten or reinstall the cap and continue driving. The light should turn off after several trips. If the light remains on, have the vehicle inspected by a NISSAN dealer.

  • If fuel is spilled on the vehicle body, rinse it off with water immediately to prevent paint damage.
