General safety recommendations  
Labels are applied at various  
points on your vehicle. They carry  
safety warnings as well as vehicle  
identification information. Do not  
remove them: they form an integral part  
of your vehicle.  
We draw your attention to the following points:  
-
The fitting of electrical equipment or accessories not listed by CITROËN may cause  
excessive current consumption and faults and failures with the electrical system of  
your vehicle. Contact a CITROËN dealer for information on the range of recommended  
accessories.  
-
As a safety measure, access to the diagnostic socket, used for the vehicle's electronic  
systems, is reserved strictly for CITROËN dealers or qualified workshops, equipped  
with the special tools required (risk of malfunctions of the vehicle's electronic systems  
that could cause breakdowns or serious accidents). The manufacturer cannot be held  
responsible if this advice is not followed.  
For any work on your vehicle, use  
a qualified workshop that has the  
technical information, skills and  
equipment required, all of which a  
CITROËN dealer is able to provide.  
-
Any modification or adaptation not intended or authorised by Automobiles CITROËN  
or carried out without meeting the technical requirements defined by the manufacturer  
would lead to the suspension of the legal and contractual warranties.  
Installation of accessory radio communication transmitters  
Before installing a radio communication transmitter, you must contact a CITROËN dealer  
for the specification of transmitters which can be fitted (frequency, maximum power,  
aerial position, specific installation requirements), in line with the Vehicle Electromagnetic  
Compatibility Directive (2004/104/EC).  
Depending on the legislation in force in the country, certain safety equipment may be  
compulsory: high visibility safety vests, warning triangles, breathalysers, spare bulbs, spare  
fuses, fire extinguisher, first aid kit, mud flaps at the rear of the vehicle...
