The current accident prevention regulations should be observed. When dealing with component parts of the airbag system safety instructions should be complied with. For more detailed information please refer to the TIS under RA no. 32 34 ... . Non-observance of the safety instructions can lead to erroneous activation and injury from the airbag system." Assembly instructions When installing cables, do not kink or damage them otherwise faults may occur which can only be localised and remedied later by extensive reworking. Costs arising in this way will not be reimbursed by BMW. The procedures, Convert heater/air-conditioner and Install IHKA wiring harness, are best shown on a dismantled heater/air-conditioner. Should specified pins be assigned, bridges, double crimping or parallel connections will have to be made. All operations are shown on a left-hand drive vehicle. Target Group Target group for these installation instructions is technical personnel who have been trained on BMW vehicles and who have specialised knowledge of vehicle electrical systems. Tasks: Carry out all maintenance, repair and installation work on BMW vehicles on own account. All operations should be carried out with the aid of the current BMW - repair instructions - circuit diagrams in a rational sequence with the prescribed tools (special tools) whilst observing the current safety regulations.
