CAUTION: Working on 12 V electrical system. 
Risk of short circuits! Risk of fire! 
  • Make sure that there is no charger  connected to the jump start terminal in the engine compartment.
  • Detach battery ground lead from battery.
  • For auxiliary batteries: Detach battery minus cables from all auxiliary batteries.
WARNING: Hot fluids. 
Risk of scalding! 
  • Conduct all work in the vehicle wearing appropriate personal protective equipment only.
WARNING: Hot surfaces. 
Risk of burning! 
  • Perform all work only on components that have cooled down.
NOTE: TECHNICAL INFORMATION 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.

Preliminary work 

WARNING: Hot surfaces. 
Risk of burning! 
  • Perform all work only on components that have cooled down.
NOTE: RISK OF DAMAGE 
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: 61 35... NOTES ON ESD (ELECTROSTATIC DISCHARGE) PROTECTION
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 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
