Before handing over the vehicle to the cus‐ tomer, make the radio ready for playing through entering the correct code. Before carrying out any welding, always disconnect the two terminals of the battery, and then cover the two poles of the battery. Before carrying out any operation producing possible sparks near the battery, always remove the vehicle battery. WARNING Switch on the ignition before connecting the battery! When the battery is connected, do not allow anyone in the vehicle! 1.3 Electronic control unit The grounding terminal of the welding machine is directly con‐ nected to parts to be welded. In addition, there shall be no electrical insulation part between the grounding terminal and the welding area. The electronic control unit and the electrical wire are not al‐ lowed to come into contact with the grounding terminal or the welding electrode. 1.3.1 Processing of the electronic control unit after repair due to a traffic accident After the traffic accident occurs, change of the electric control unit will not be necessary until there is at least one of the follow‐ ing situations: ♦ The housing is significantly deformed or damaged. ♦ The instrument appearance is not damaged, but the bearing surface or holder is deformed. ♦ The plug connection is damaged or rusted due to moisture. ♦ The functional check or unit self-diagnosis procedure may show fault“Control Unit Damaged”. If an electronic part is removed as required by the service oper‐ ation, such as ABS control unit, and then reused, its function shall be tested according to existing materials after installation, such as using V.A.G self-diagnosis procedure.

C o p yrig ht b y V olk s w a g e n A G . 1.4 Paint, glass, soft pad and trim Other vehicles under no protection are not allowed to be parked in the operation area for the body repair. (There is a risk of fire due to spark, battery, paint and damaged glass). 1.5 Fuel tank or fuel delivery pipeline An extreme care shall be exercised in case that grinding and welding operations are carried out in the fuel tank or other fuel delivery part area. These parts must be removed in case of potential safety hazards. 1.6 Air conditioner After refrigerant is added into the air conditioner, its compo‐ nents are allowed to be neither welded, nor brazed or soldered. If there is a risk to heat the air conditioner components during welding and soldering on the vehicle, welding is not allowed either. In term of paint repair, temperature of the object in the drying oven or the preheating area is only allowed to reach 80°C, as there will be a large overpressure in the heated equip‐ ment, which may cause an equipment burst. Note In case that welding is performed near the refrigerant hose, it is also necessary to withdraw the refrigerant in the refrigerant circuit. Invisible ultraviolet will be released during welding, and they may infiltrate into the refrigerant hose and break down the refrigerant. 1.6.1 Remedial measures: Suck the refrigerant circuit ⇒ heater and air conditioner; Rep. gr. 87. The drained air conditioner may only be filled in a maintenance shop equipped with special V.A.G equipment. In case of re‐ quired safety measures, the equipment must be turned on to drain the refrigerant. If necessary during repairing the vehicle, drain the refrigerant circuit, and avoid contact with the refrigerant or the refrigerant vapour! Wear rubber gloves and goggles to protect your hands and eyes! The reason is that refrigerant split onto the unprotected human body parts may cause a frostbite in a serious situation. WARNING It is suggested to prepare a rinsing bottle for flushing your eyes. If liquid refrigerant enters your eyes, rinse immediately with water for 15 minutes. Then wash your eyes with eye drop, and go to see an oph‐ thalmologist right away even if your eyes do not hurt. You must tell the doctor that the frostbite is caused by refrigerant R12 or R134a. If the refrigerant is still in contact with other parts of the body even though the safety measures are followed, these areas also need to be thoroughly rinsed with cold water immediate‐ ly for at least 15 minutes.

C o p yrig ht b y V olk s w a g e n A G . Although refrigerant causes no fire risk, smoking is not allowed in a room where the refrigerant is placed. The reason is that a lit cigarette has a high temperature which may cause chemical decomposition of the refrigerant gas. Inhalation of the toxic de‐ composition generated by this will result in an irritable cough and nausea. 1.7 Airbag System Repair instructions ⇒ internal body repair; Rep. gr. 69. During operation on the airbag system as well as correction operation within the body repair scope, the battery grounding must be disconnected. WARNING Switch on the ignition before connecting the battery! When the battery is connected, do not allow anyone in the vehicle! The temperature of the airbag components must not exceed 100°C, not even instantaneously. The airbag components are not allowed to come into contact with grease, cleaning agent, oil or the like. The mechanically damaged airbag components must be re‐ placed. =>Disposal instructions ⇒ page 27 . After coming in to contact with a triggered airbag unit, wash your hands! 1.8 Check the seat belts WARNING Systematically check the seat belt system every time after an accident! If one item is found damaged according to the items to be checked, the customer must be informed of the necessity to replace the seat belt. Items to be checked: ♦ Belt body ♦ Automatic retractor (locking function) ♦ Visual inspection of the seat belt buckle ♦ Seat belt buckle function ♦ Seat belt guide member and tongue ♦ Fixing piece and fixing point ♦ Automatic waist seat belt retractor Note If the customer refuses to replace a damaged seat belt, corre‐ sponding notes must be made.

Checking – Vigorously pull the seat belt out of the automatic retractor. • No locking function-replace the seat belt together with the seat belt buckle. • If the seat belt extraction or retraction function does not work, first check that whether the automatic seat belt retrac‐ tor is in the correct position. • The second locking function is triggered through change of the vehicle operation process (locking function associated with the vehicle). Checking – Fasten the seat belts. – Accelerate the vehicle to 20 km/h, and then perform an emergency braking using the foot brake. • If the seat belt is not locked by the locking mechanism dur‐ ing the braking process, replace the seat belt together with the seat belt buckle. WARNING For safety reason, this driving test shall be performed on a road segment without other running vehicles, in order to avoid posing a danger to the other road users. 1.8.3 Visual inspection of the seat belt buck‐ le – Check whether there is cracking and peeling in the seat belt buckle. • Replace the seat belt together with the seat belt buckle in case of damage. 1.8.4 Seat belt buckle function Check the seat belt locking mechanism: – Push the tongue into the seat belt buckle till you hear the engagement sound. Vigorously pull the seat belt to check whether the closing mechanism locks. • Even there is only one locking failure of the tongue in the seat belt buckle for over 5 inspections, the seat belt must be replaced together with the seat belt buckle. Check the unlocking mechanism: – Use your finger to press the button on the seat belt buckle to release the seat belt. When the belt body is released, the tongue must automatically come out of the seat belt buckle. • Check for least 5 times. As long as the latch does not pop out for at least one time, replace the seat belt together with the seat belt buckle. General InformationBody Repairs, General Body Repairs - Edition 05.2019 1.

WARNING it is not never permissible to use lubricant on the button of the seat belt buckle to eliminate the noise or blockage in case of the seat belt operation. 1.8.5 Seat belt guide member and tongue After the seat belt system is stressed (when the seat belt is damaged in an accident), there will be some small parallel clefts on the guide member with a plastic coating. (This is different from the wear often seen, and the latter shows smooth wear without fine patterns). – Check the plastic materials for deformation, peeling and cracking. • Replace the seat belt together with the seat belt buckle in case of clefts and/or damages. 1.8.6 Fixing piece and fixing point ♦ The fixing strip/bracket is deformed (stretched). ♦ The height adjustment device does not work. ♦ Fixing points (seat, door post or vehicle floor) are deformed or the threads are damaged. • Replace the seat belt together with the seat belt buckle in case of damage found on these parts. • Replace the fixing points.
