Description
The telephone system in the vehicle is available in three options: Tel 1, UHP and OnStar.

Tel 1
Tel 1 means that the car is prepared for an external mobile telephone connection that is connected to the system via a connector in the dashboard. The roof antenna and antenna cable are factory-mounted. Tel 1 means that the telephone keypad must be used for dialling. The microphone in the roof panel is used for speaking and the car's standard audio system is used as speakers. The volume is adjusted during a call via the steering wheel controls or the volume control of the audio system. The phone is charged automatically.

UHP
UHP means that the car is equipped with a UHP control module that is connected to the microphone, radio unit, Ibus and a bracket. The bracket is connected to the roof antenna and is located in the floor console's storage compartment. The holder, which is unique to the mobile phone, is fastened and connected to the bracket. SID displays the selected telephone functions.

The steering wheel controls can be used for incoming and outgoing phone calls, volume adjustment and to browse among and select numbers from the phone book or call list. The microphone in the roof panel is used for speaking and the car's standard audio system is used as speakers. The making and storage of calls can be voice-controlled.

The UHP control module is connected to the wiring harness and communicates on the car's I-bus. The UHP control module is fastened to the floor with a bracket in front of the gear lever/gear selector.

There are two ways to connect the mobile phone to the car's UHP system:
^ The mobile phone with holder is fastened into the car's bracket. The holder must be designed for the mobile phone. When the mobile phone battery is to be charged and connected to the vehicle antenna, it is put in the holder and anchored to the bracket.
^ Wireless connection between the mobile phone and system is possible with the Bluetooth function. The UHP control module has the *Bluetooth function with integrated antenna. Mobile phones with Bluetooth can be coupled with UHP. The mobile phone then uses its own battery and antenna.

In both cases, the mobile phone is controlled with the steering wheel controls and voice recognition. SID displays selected telephone functions and indication that one is within an area with GSM coverage.

*Bluetooth is wireless technology that works in the license-free ISM band (Industrial Scientific Medical) of 2.4 GHz. Bluetooth has a short range and is designed for communication in a personal network, such as between a mobile phone and a computer.

OnStar
With the help of OnStar, you obtain guidance with several services and emergency assistance in the event of an accident. Contact OnStar simply by pressing the OnStar button on the dashboard. The system then links the car with OnStar, where you get contact with people who can help with a number of traffic services. The system calls the alarm center in the event of a collision in which the airbags were deployed. With the help of GPS, the car's position is located, which makes it easier for rescue workers to arrive to the scene more quickly.
