GENERAL INFORMATION 
NOTES ON SELF-LOCKING NUTS AND BOLTS - AH00.00-N-0001-01A 
All models  
Important repair information  
 Bolts with locking splines, micro-encapsulated bolts and self-locking nuts must always be replaced after 
being used once. 
There is an increased risk of injury when unscrewing micro-encapsulated bolts due to the sudden breakaway 
torque. 
Before new micro-encapsulated bolts are screwed in, the mating thread must be re-cut in order to remove all the 
residue of the old bolt locking compound. 
MEASURES FOR PREVENTING DAMAGE TO VEHICLES OR COMPONENTS WHEN PERFORMING ARC WELDING 
WORK - AH00.00-N-0005-01A 
All models  
 The following measures must be taken before welding in order to prevent damage to various vehicle 
components: 
1 Have fire extinguishers at the ready.  
2 The negative terminal of the battery must be disconnected and covered up.  
3 In vehicle with airbags the red, 12-pin test connection/plug-in connection must be disconnected no 
sooner than two seconds after the battery has been disconnected (risk of unwanted activation).  
6 Attach protective shields to prevent flying sparks and radiated heat in endangered areas.  
7 Do not touch electronics housings or electrical cables with the welding electrode or the welder's ground 
connection.  
8 If two parts are being welded together, both parts must be attached to the welder's negative clamp.  
9 Make direct connection between the electrical welder's ground connection and the part being welded. 
Ensure that there are no electrically insulating parts between the ground connection and the welding 
point.  
10 Protect or remove any parts that are sensitive to heat such as plastic cables.  
11 Remove electrical cables that are laid in cavities and/or pipelines, covered containers and electrical 
components from the danger area before welding.  
12 If possible, the points where the welded part is being attached to the vehicle and the ground terminal is 
attached to the electrical welder must be bare; remove all traces of paint, corrosion, oil, grease and

soiling.  
13 The ground terminal of the welder must not be attached to the transmission. The welding current can 
cause arcing at the bearing points inside the transmission. The structural changes that this causes lead to 
premature failure of the equipment.
