Turbocharger

After driving at freeway speeds or up a long hill, trailer towing for a long time, idle the engine at least 30 seconds before stopping it. Otherwise, the turbocharger could be damaged. However, when i-stop operates, idling is unnecessary.

Racing or over-revving the engine, particularly after it's just been started, can damage the turbocharger.

To protect the engine from damage, the engine is designed so that it cannot be raced just after starting it in extremely cold weather.
