RF signals may affect improperly installed or inadequately shielded
electronic systems in motor vehicles (for example, electronic fuel
injection systems, electronic antiskid/antilock braking systems, electronic
[ 163 ]
speed control systems, air bag systems). Check with the manufacturer or
its representative regarding your vehicle. You should also consult the
manufacturer of any equipment that has been added to your vehicle.
Switch your phone off in any facility where posted notices so require.
Potentially explosive atmospheres
Switch off your phone when in any area with a potentially explosive
atmosphere and obey all signs and instructions. Sparks in such areas could
cause an explosion or fire resulting in bodily injury or even death.
Users are advised to switch off the phone when at a refueling point
(service station). Users are reminded of the need to observe restrictions on
the use of radio equipment in fuel depots (fuel storage and distribution
areas), chemical plants, or where blasting operations are in progress.
Areas with a potentially explosive atmosphere are often but not always
clearly marked. They include below deck on boats; chemical transfer or
storage facilities; vehicles using liquefied petroleum gas (such as propane
or butane); areas where the air contains chemicals or particles, such as
grain, dust, or metal powders; and any other area where you would
normally be advised to turn off your vehicle engine.
