Safety and installation instructions
Warning
To prevent the risk of short circuits, always disconnect the negative
terminal of the vehicle's electrical system before working on it.
If the vehicle has an additional battery, its negative terminal should
also be disconnected.
Warning
Inadequate cable connections can cause short circuits, resulting in:
– Cable fires
– The airbag being triggered
– Damage to electronic control equipment
– Electrical malfunctions (indicators, brake light, horn, ignition,
lights)
Please observe the following instructions:
When working on the following supply lines, only use insulated cable lugs,
plugs and tab sleeves.
– 30 (direct supply from positive battery terminal)
– 15 (connected positive terminal, behind the battery)
– 31 (return cable from the battery, earth)
Do not use terminal strips.
Use a crimping tool to connect the cables.
For connections to wire 31 (earth):
– Screw on the cable using a cable lug and serrated washer with one of
the vehicle's earth bolts
– Screw the cable to the bodywork using a cable lug and a self-tapping
screw
Make sure there is a good earth connection.
If you disconnect the negative terminal of the battery, all data stored in the
volatile memories will be lost.
The following data must be set again, depending on the vehicle
equipment options:
– Radio code
– Vehicle clock
– Timer
– On-board computer
– Seat position
You can find instructions for making these settings in the appropriate
operating instructions.
