These controls are located on the right side of the steering wheel.

(Volume): Press the up or down arrow on the volume control to increase or decrease the sound level of all cell phone communications, such as incoming calls, voice recognition and memo playback. The selected volume levels will be saved in memory for the next time these features are used. Other audio volume levels, for example the CD or radio volume, will not be affected. The volume arrows will only change the volume of the feature currently in use at the time of adjustment.

(Select): Press the up arrow on the select control to access a listing of the last five numbers called using the voice recognition feature. Press the down arrow on the select control to access the list of phone numbers stored in the handset's address book. The cellular phone system can access up to 99 numbers stored in the handset. Additional numbers can be accessed using the handset key pad. Once you enter either list, you can press the up or down arrow to scroll through the stored numbers displayed on the DIC. If you see a number you wish to call while scrolling through either list, press the voice recognition control and the cell phone will dial the number currently displayed on the DIC.

The steering wheel controls can be used to operate the system when either the ignition is in ACCESSORY or ON, or when Retained Accessory Power (RAP) is active.
