these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the gas station.
Before touching the fuel noz-

whilst refuelling. Electric cur-
rent and/or electronic interfer-
ence from mobile phones can
potentially ignite fuel vapours
and cause a fire.
Do not get back into a vehicle
once you have begun refu-
elling. You can generate a
build-up of static electricity by
touching, rubbing or sliding
against any item or fabric capa-
ble of producing static electric-
ity. Static electricity discharge
can ignite fuel vapours causing
a fire. If you must re-enter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other petrol
source, with your bare hand.(Continued)
