Hyundai Azera: Fuel requirements

Your new vehicle is designed to use only unleaded fuel having a pump octane number ((R+M)/2) of 87 (Research Octane Number 91) or higher.

Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL, as well as minimize exhaust emissions and spark plug fouling.

Never add any fuel system cleaning agents to the fuel tank other than what has been specified. (Consult an authorized HYUNDAI dealer for details.)

WARNING - Refueling

• Do not "top off" after the nozzle automatically shuts off when refueling. Attempts to force more fuel into the tank can cause fuel overflow onto you and the ground causing a risk of fire.
• Always check that the fuel cap is installed securely to prevent fuel spillage in the event of an accident.

✽ NOTICE

Tighten the cap until it clicks one time, otherwise the warning light “Check Fuel Cap” will illuminate on the LCD display.
