Checking the timings of the camshaft

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: SAFETY INSTRUCTIONS ON HANDLING HYBRID CARS .
For additional information see: NOTES ON REPAIR OF HIGH-VOLTAGE BATTERY UNIT .

WARNING: Hot surfaces .
Risk of burning!

Perform all work only on components that have cooled down.

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: TECHNICAL INFORMATION
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.

NOTE: TECHNICAL INFORMATION
Only G05 and G07
On vehicles with an active stabilizer (ARS), the fan cowl must be removed to crank the engine.
