Safety and General Information - 71 
 
Vehicles 
RF signals are liable to influence improperly installed electronic systems or 
systems in motorized vehicles that are inadequately protected. Consult your 
vehicle manufacturer or its representative. Make sure to always confer with the 
manufacturer of any item of equipment that you add to your vehicle. 
 
Facilities with Warning Signs 
Make sure to turn off your phone in any facility that posts warning signs requiring 
you to do so. 
 
Explosive Atmospheres
 
To prevent involvement in explosions, turn off your phone in “explosive” areas or 
in areas with “Turn off your radio device” signs. Ensure compliance with all signs 
and instructions. 
 
Potentially Explosive Areas
 
When you are in an area where the atmosphere is explosive (potentially 
explosive), turn off your phone device.
 
These areas are often indicated (though not always). Included are fuelling areas 
for vehicles, (gas stations), below decks on boats, fuel or chemical transfer or 
storage facilities, areas where the air contains chemical substances (or particles, 
granules, dust or metal powders), and any other area where you would be advised 
to turn off your vehicle engine.
 
 
For Vehicles with an Installed Air Bag 
An air bag inflates with great force. Do not place objects, including parts of 
installed equipment or portable equipment in the area of the air bag, or in its 
deployment area. Portable equipment for the vehicle that is installed defectively in 
close proximity to an air bag that inflates is liable to cause severe injuries.
