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.
