WARNING
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 handsfree
device and only use the telephone when
weather, road and traffic conditions permit.
Some jurisdictions prohibit the driver from
using a mobile phone while driving a vehicle.
