it's fine they just write that on there in case you need a 120 volt adapter. 13.8 is the reccommended adapter. i have a 2001 TL also and with my passport 8500 having a voltage display on ti the car is almost always at 14.2 volts. but for some reason when you turn the AC off it will be closer to 13.8- 14.0 wierd...
