Nissan Sentra Owners Manual: Car phone or CB radio
A cellular phone should not be used for any purpose while driving so full attention may be given to vehicle operation.
Some jurisdictions prohibit the use of cellular phones while driving.
If you must make a call while your vehicle is in motion, the hands free cellular phone operational mode is highly recommended. Exercise extreme caution at all times so full attention may be given to vehicle operation.
If you are unable to devote full attention to vehicle operation while talking on the phone, pull off the road to a safe location and stop your vehicle.
