pump and never let children
pump fuel.
.Before touching the fill nozzle, touch a
metallic object to discharge static
electricity from your body.
.Fuel can spray out if the fill nozzle is
inserted too quickly. This spray can
happen if the tank is nearly full, and is
more likely in hot weather. Insert the

engine stalling and damage to the fuel
system.

Be careful not to spill fuel. Wait five seconds
after you have finished pumping before
removing the fill nozzle. Clean fuel from
painted surfaces as soon as possible. See
Exterior Care 0283. Push the fuel door
closed until it latches.
{Warning
If a fire starts while you are refueling, do

flow of fuel by shutting off the pump or
by notifying the station attendant. Leave
