When refuelling your vehicle, you should

  1. keep the engine running.
  2. keep the radio on.
  3. smoke a cigarette.
  4. keep the nozzle in contact with the fuel filler intake. ✓

Answer: D. keep the nozzle in contact with the fuel filler intake.

Keep the fuel nozzle in contact with the filler pipe on your vehicle the whole time you refuel.

Why this is the answer

The handbook says not to refuel while the engine is running, while the on-board radio is transmitting, or when an open flame is present. It also says to hold the fuel hose nozzle against the filler pipe at all times so the connection is grounded. That makes keeping the nozzle in contact the right action. The point is to ground the connection and avoid ignition sources during fuelling. The same section warns against smoking in garages or near fuelling areas.

Why the other answers are wrong

Remember it

Think of the nozzle as the grounding link: touch it to the filler pipe and leave it there until fuelling is done.
