Maintenance and care
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
When refueling always shut the engine off and never allow
sparks or open flames near the filler neck. Never smoke while
refueling. Fuel vapor is extremely hazardous under certain conditions.
Care should be taken to avoid inhaling excess fumes.
The flow of fuel through a fuel pump nozzle can produce static
electricity, which can cause a fire if fuel is pumped into an
ungrounded fuel container.
Use the following guidelines to avoid static build-up when filling an
ungrounded fuel container:
• Place approved fuel container on the ground.
• DO NOT fill a fuel container while it is in the vehicle.
• Keep the fuel pump nozzle in contact with the fuel container while
filling.
• DO NOT use a device that would hold the fuel pump handle in the fill
position.

and could damage your vehicle.

components.
