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 rec-
ommend that you pull over to a safe location 
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the 
hands-free device and only use the tele-
phone when weather, road, and traffic con-
ditions permit.
Some jurisdictions prohibit the driver from 
using a cellular telephone while driving a ve-

ly 14 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, pos-
sibly resulting in an accident and/or 
personal injury.
