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 weather, 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 
44 feet (approximately 13.5 m) every 
second.
Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, 
possibly resulting in an accident and 
personal injury.
