On/Off switch
Press the knob to turn on or
switch off the radio.
Volume control
Turn the knob clockwise to
increase volume. Volume
control is electronic and lacks an end stop. If
you have a steering wheel keypad, increase
or decrease volume with (+) or (–) buttons.
Low battery voltage
If battery voltage is low, a text appears in the
combined instrument unit display. The ener-
gy economy function of the car may switch
off the radio. Charge the battery by starting
the engine.
Volume control – TP/PTY/NEWS
If a cassette or CD is playing when the radio
receives a traffic bulletin, news or selected
programme type, the function is interrupted
and the bulletin or message is broadcast with
the volume selected for traffic information,
news or programme type.
When the bulletin or message is finished, the
unit immediately returns to the previously set
volume and resumes playing the cassette
or CD.
The audio system can be equipped with dif-
ferent options and different versions. There
are three audio system versions:
• Performance
• High Performance
• Premium Sound.
FM and AM radio with RDS and CD player is
however included in each version.
AUX
Input for external audio source (AUX) 3.5 mm
The AUX input can be used for connecting an
MP3 player for example.
Sometimes the AUX external audio source
can be heard at a different volume to the in-
ternal audio sources, e.g. the CD player. If
the audio volume of the external audio
source is too high then the sound quality may
be impaired. Prevent this by adjusting the in-
put volume of the AUX input.
