There is a difference in sound quality between the different audio sources (radio, CD…).
For optimum sound quality, the audio settings (Volume, Bass, Treble, Ambience, Loudness) can be adapted to the different sound sou rces, which may result in audible differences when changing source (rad io, CD…).
Check that the audio settings (Volume, Bass, Treble, Ambience, Loudness) are adapted to the sources listened to. It is advisable to set the AUDIO functions (Bass, Treble, Front-Rear Fader, Left-Right Balance) to the middle position, select the musical ambience "None" and set the loudness correction to the "Active" position in CD mode or to the "Inactive" position in radio mode.
When changing the settings for treble and bass, the ambience setting is deselected.
When changing the ambience setting, treble and bass are reset to zero.
Choosing an ambience imposes settings for treble and bass. Modifying one without the other is not possible. Modify the treble and bass settings or the ambience setting to obtain the desired sound quality.
When changing the balance setting, distribution is deselected.
Choosing a distribution setting imposes a balance setting. Modifying one without the other is not possible. Modify the balance setting or the distribution setting to obtain the desired sound quality.

"ISOFIX" mountings
There are three rings for each seat: - two rings A , located between the vehicle seat back and cushion, indicated by a label,
- a ring B , behind the seat, referred to as the Top Tether for fixing the upper strap. ther
This ISOFIX mounting system provides fast, reliable and safe fitting of the child seat in your vehicle.
The incorrect installation of a child seat
in a vehicle compromises the child's protection in the event of an accident.
For information regarding the ISOFIX child seats which can be installed in your vehicle, refer to the table showing the locations for
installing ISOFIX child seats.
When fitting an ISOFIX child seat to the left hand rear seat, before fitting the seat, first move the centre rear seat belt towards the middle of the vehicle, so as to avoid the seat inter fering with the operation of the seat belt.
The ISOFIX child seats are fitted with two latches which are secured on the two rings A . Some seats also have an upper strap , known as the Top Tether, which is attached to ring B . To attach this strap, raise the vehicle seat's head restraint then pass the hook between its rods. Then fix the hook on ring B and tighten the upper strap.
