Before installing this type of accessory (particularly for transmitters/receivers:
frequency bandwidth, power level, position of the aerial, etc.), make sure it is compatible
with your vehicle.
Before carrying out any towing, set the gearbox to NN position (see "Automatic gearbox" in Section 2), unlock the steering column then
release the parking brake (see "Electronic parking brake" in Section 2).
If the gearbox cannot be set to position N, please contact an Authorised Dealer.
