operating temperature as soon as possible. This is best achieved by driving with a light foot on the
accelerator pedal for a few minutes after starting, rather than prolonged idling.

Turbo caution

Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast
enough to prevent engine damage.
Before switching off the engine, let it operate at idle for a short time to allow the spinning of the turbo-
compressor's turbine vanes to slow. After hard driving, this idle time should last a couple of minutes,
during which the vanes will slow and the compressor will cool down while still receiving lubrication. If
the turbine vanes are spinning at high speeds when the engine is switched off, there is a great risk of heat
damage and/or turbine seizure due to lack of lubrication.
Do not race the engine just prior to switching off!
