Central locking

Unlike the previous systems, a two-motor lock is used here. The locked motor switches the central locking system from unlocked to locked or vice versa. The safe motor switches the central locking system from locked to safe or vice versa. The central locking system provides for three different locking conditions Action 1 If the lock is activated once, the so-called Safe locking - door secured The doors can be opened only with the key, but not with the inside door handles. Action 2 If the door...

System description

The highly accurate satellite-based navigation system permits rapid and sure guidance to an input destination in areas for which a digitized road map on CD-ROM is available. Route guidance is realised by means of driving instructions with voice output in various selectable national languages, supported by arrow or map displays on the screen. Buttons for selecting the various audio sources (AM FM tuner, cassette, CD) are located on the left side of the front panel. The RDS names of the stations...

Switch convertible top compartment

The switch connects ground to the control module. The switch has been omitted in vehicles as from the Y-range. In the event of an alarm, the horn is supplied with positive potential by the control module. If the positive supply for the alarm horn is interrupted, the visual alarm is triggered via the direction indicator lights and the interior lights. The signal converter obtains the transponder code from the signals sent by the transponder, and then sends this code on to the alarm system...

Activating and deactivating alarm system

The alarm system is activated by a ground signal at the activation input or by an activation signal from the hand-held transmitter. The activation of the system is ignored if terminal 86 S, terminal 15 or a valid transponder key is recognised. If for some reason it is not possible to lock the central locking system with a single locking command, the alarm system is not activated. Activation of the alarm system cannot be achieved until the central locking system is locked if necessary manually...

Remedy

On-board computer Disconnection of the vehicle battery deletes the memories for average speed and average consumption. As a result, the displayed range on remaining fuel can be markedly different or even 0. The outside temperature indicator loses its memory effect. In other words, the indicated outside temperature can be too high due to the heat radiated when the vehicle is hot. The radio reverts to the Code function when the battery is disconnected and is thus no...

Behaviour in the case of servicing

An activated tilt sensor will trigger an alarm. In order to carry out servicing work the alarm siren must be switched off before the work is commenced. To switch it off, insert the vehicle key with valid transponder into the ignition lock and rotate to actuate the buzzer contact. Components can be removed with triggering the alarm as long as the vehicle key remains inserted.
