Wa r n i n g !
A driver’s attention to the road must always be his/
her primary focus when driving. For your safety
and the safety of others, we recommend that you
pull over to a safe location and stop before placing
or taking a telephone call. If you choose to use the
telephone while driving, please use the hands-free
device and only use the telephone when road and
traffic conditions permit.Some jurisdictions prohibit the driver from using a
cellular telephone while driving a vehicle.Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is covering
a distance of approximately 50 feet (approximately
14 m ) e v e r y s e c o n d . Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so could
lead to a malfunction of the vehicle’s electronic
system, possibly resulting in an accident and
personal injury.
Wa r n i n g !
Some jurisdictions prohibit the driver from using a
cellular telephone while driving a vehicle. Whether
or not prohibited by law, for safety reasons, the
driver should not use the cellular telephone while
the vehicle is in motion.
