T-screw and swing the subwoofer to
the side.
Always observe all safety precau-
tions posted at the service station

fuel containers in your vehicle. Whether
empty or full, these containers can leak,
cause an explosion, or lead to fire in the
event of a collision.<
Simple and environmentally
friendly
Open the fuel filler cap carefully to
prevent fuel from spraying out.
Fuel spray may cause injury.
Do not top off. Topping off may cause
fuel spillage.<
Keep the filler cap in the bracket
attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refu-
eling
>results in premature pump shutoff
>and will reduce the effectiveness of
the vapor recovery system on the
pump.
