Turbocharger Information
í
The turbocharger greatly enhances engine power. Its advanced design provides improved
operation and requires minimum additional maintenance. To get maximum performance
from your turbocharged engine, take note of the following tips:
l
The turbocharged engine is designed for optimal operation with premium unleaded
gasoline (page 4-2). Do not use fuel with a lower octane rating. Extra fuel additives are
NOT recommended.
l
Change the engine oil and filter using the turbo engine interval outlined in the
maintenance schedule (for your driving condition).
l
Use only the recommended engine oil (page 8-18). Extra oil additives are NOT
recommended.
l
After driving at freeway speeds or up a long hill, idle the engine at least 30 seconds to
cool the turbo before turning off the engine. Avoid simply shutting the engine off
abruptly after a hard or long drive. Damage to the turbocharger may result.
l
Do not race or over-rev the engine when starting. This should not be done with ANY
engine, especially not with one that's turbocharged.
l
Do not add any aftermarket devices to alter the engine's ignition timing, fuel delivery, or
turbo boost pressure. This may lead to serious engine damage and may void your
warranty.
