General Information

Vehicles with a Universal Handsfree Phone (UHP) system can use a Bluetooth® capable mobile phone with a Hands-Free Profile to make and receive phone calls. The infotainment system and voice control are used to control the system. The system can be used while the ignition is in ON/RUN or ACC/ACCESSORY. The range of the UHP system can be up to 10m (33 ft). Not all phones support all functions and not all phones work with the UHP system.
