WARNING: High-voltage system.
The high-voltage system operates on the basis of hazardous, electrical voltage and high currents. Mortal hazard through electric shock!

All work on the high-voltage system may only be carried out by specially trained and technically experienced personnel.
For additional information see:
61 00... SAFETY INSTRUCTIONS ON HANDLING HYBRID CARS
For additional information see:
61 25... NOTES ON REPAIR OF HIGH-VOLTAGE BATTERY UNIT

WARNING: 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: Working on fuel system.
Risk of fire! Danger of explosion!

When working on the fuel system, make sure the workstation has sufficient ventilation, e.g., by means of extraction.
Tightly seal off open lines and connections; collect any leakage fuel directly at the point of exit.
No fire, sparks, open flames or smoking.

CAUTION: On releasing high pressure line, fuel may emerge at high speed.
Injury hazard!

Wear suitable personal protective equipment.
Before performing any installation work, allow cooling system to cool down to less than 40°C.
Note warnings on cylinder head cover.

NOTE: RISK OF DAMAGE
Damage to battery terminal, the safety battery terminal or the intelligent battery sensor (IBS).
Damaged battery terminals can lead to malfunctions or vehicle electrical system faults.
