Warning
Fuel vapors and fuel fires burn violently and can cause injury or death.
This spray can happen if the tank is nearly full, and is more likely in hot weather.
Open the fuel cap slowly and wait for any hiss noise to stop then unscrew the cap all the way.

The tethered fuel cap is behind a hinged fuel door on the passenger side of the vehicle. To open the fuel filler door, lift the fuel door release lever. The lever is on the floor, on the left front side of the driver seat.
The fuel door is unlocked when the vehicle is unlocked. Locking the vehicle locks the fuel door.

To remove the fuel cap, turn it slowly counterclockwise.
Be careful not to spill fuel. Do not top off or overfill the tank and wait a few seconds after you have finished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Exterior Care on page 10-70.
When replacing the fuel cap, turn it clockwise until it clicks. Make sure the cap is fully installed. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See Malfunction Indicator Lamp on page 5-12.
Push the fuel door closed until it latches.
Warning
If a fire starts while you are refueling, do not remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant.
Leave the area immediately.
Caution
If a new fuel cap is needed, be sure to get the right type of cap from your dealer. The wrong type of fuel cap may not fit properly, may cause the malfunction indicator lamp to light, and could damage the fuel tank and emissions system. See Malfunction Indicator Lamp on page 5-12.
