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
