Opel Blazer Operation & Maintenance Instructions Manual page 64

Remove the fuel filler cap by slowly turning it
counterclockwise. Replace it by turning it clockwise.
When you put the cap back on, continue to turn it
clockwise until you hear a clicking noise.
CAUTION:
If you open the cap rapidly while pressure inside
the tank is high, gasoline may spray out from the
tank. Before you fully open the cap, turn it
slightly to release the pressure from inside the
tank to avoid possible injury.
NOTICE:
If you have to get a new cap, be sure to get the
right one. Otherwise the cap might not have
the proper venting. This could lead to serious
fuel system and other damage. Your dealer
knows the correct cap for your vehicle.
