Damage to or destruction of electrical components.
Electrostatic discharge.
Damage to or destruction of electrical components.
- Leave the electrical components in their original packaging until they are being installed. Only use the original packaging for returning the product. Always package removed components straight away.
- Read and comply with user information on using the associated special tool 12 7 060.
- Only tap the housings of electrical components. Do not tap pins or multi-pin connectors directly.
- Wear electrically conductive clothing and antistatic shoes (with ESD symbol).
- For additional information see: NOTES ON ESD (ELECTROSTATIC DISCHARGE) PROTECTION .
NOTE:
RISK OF DAMAGE
Damage to steering column switch cluster (SZL).
The steering column switch cluster (SZL) or the coil spring cassette can be damaged by twisting the steering wheel if the lower steering shaft (or the universal joint) is separated from the steering gear or the steering column.

NOTE:
TECHNICAL INFORMATION
Immobilization period-long fill of coolant!
Do not reuse used coolant.
When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be emptied and refilled.
In the case of other removal work involving the draining of part quantities of coolant, the coolant level must be topped up with new coolant.

NOTE:
TECHNICAL INFORMATION
Filling without the vacuum filling equipment (watering can filling) is not permitted .
If this is not observed, there is a risk of component damage or engine damage.
The filling specification must be observed.
It is essential to visually check the vacuum filling equipment before use to check that it is functioning correctly and clean.
It is not permissible to operate the vehicle if the filling procedure has not been fully completed. Otherwise there may be functional limitations (degradation) or overheating.
A bleeding procedure is required after a part has been exchanged in the cooling system and/or after refilling the cooling system.
