Caution! In order to avoid damage to the engine and the exhaust turbocharger due to insufficient lube oil supply:
☞ Do not run the cold engine at full throttle when starting and • let the engine warm up at low idling revs (for about 30 seconds)
☞ When switching off the engine: • Do not switch off the engine from full throttle • Let the engine run at idling speed for about 2 minutes
☞ Check that the following telltales have gone out: • Telltale 54 • Telltale 52 • Telltale 47
