Anti-lock Braking System (ABS)<br />
Service the air cleaner filter elements as specified in "PART<br />
8: MAINTENANCE AND SERVICE". If your vehicle is<br />
equipped with an optional air inlet restriction indicator, service<br />
the filter elements when the air inlet restriction indicator<br />
locks in the extreme Up position.<br />
Paper elements require care and proper handling because<br />
they are critical to engine service life.<br />
Turbocharger<br />
When servicing the air intake and exhaust systems on a<br />
turbocharged engine, check the items that follow. If you<br />
detect any deficiencies, take the vehicle to an authorized<br />
dealer for servicing. Delay could lead to severe and expensive<br />
damage to your vehicle.<br />
WARNING! Do not operate engine with turbocharger<br />
intake piping disconnected. Working<br />
around a turbocharger with the intake<br />
piping removed can be dangerous. A suction<br />
is created when the engine is running. This<br />
suction could draw your hand or anything else<br />
near it into the impeller fan. You could be seriously<br />
injured. Always keep the intake piping<br />
connected when you will be running the engine.<br />
PART 8: MAINTENANCE AND SERVICE<br />
• Lubricating System: Check the oil lines, housing, and<br />

Leaks could mean you have damaged oil lines or oil<br />
seals.<br />
• Manifold: With the engine operating, check for leaking<br />
manifold or flange gaskets.<br />
• High Frequency Vibration: Vibration may indicate<br />
turbo rotor imbalance. Have your dealer investigate<br />
this immediately.<br />
Exhaust System<br />
Details of inspection and maintenance of your exhaust system<br />
are covered under "Noise Control System".<br />
