Refueling
When handling fuels always
observe any safety guidelines
posted at the service station. Never
carry spare fuel containers in your vehi-
cle. Whether empty or full, these con-
tainers can leak, cause an explosion, or
lead to fire in the event of a collision.<
Observe the following when
refueling
Open the 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 refuel-
ing
>results in premature pump shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
The fuel tank is full when the filler noz-
zle clicks off the first time.

To close the fuel filler cap:
Fit the cap and turn it clockwise until
you clearly hear a click.
Close the filler cap carefully after
refueling until a click is heard.
While closing, be sure not to squeeze
the strap which is fastened to the cap.
A loose or missing cap will activate the
message "CHECK GAS CAP" in the
Check Control
* or the Check Gas Cap
lamp
