This input jack is not an audio output; do not plug headphones into the front auxiliary input jack.

Drivers are encouraged to set up any auxiliary device while the vehicle is in P (Park). See Defensive Driving on page 9‑3 for more information on driver distraction.

To use a portable audio player, connect a 3.5mm (1/8 in) cable to the radio's front auxiliary input jack.

When a device is connected, press the radio CD/AUX button to begin playing audio from the device over the vehicle speakers.
