7.1 Warnings and Notices

7.1.1 Warnings and Notices

Anti-Corrosion Materials

Warning!

Notice: If the power steering system has been serviced,
an accurate fluid level reading cannot be obtained unless
air is bled from the steering system. The air in the fluid
may cause pump cavitation noise and may cause pump
damage over a period of time.

Power Steering Hose Disconnected

Warning!

Notice: Do not start the vehicle with any power steering
gear inlet or outlet hoses disconnected. When
disconnected, plug or cap all openings of components.
Failure to do so could result in contamination or loss of
power steering fluid and damage to the system.

Steering Wheel in the Full Turn Position

Warning!

Notice: Do not hold the steering wheel in the full turn
position longer than 5 s, as damage to the steering pump
may result.

Using Proper Power Steering Fluid

Warning!

Notice: When adding fluid or making a complete fluid
change, always use DEXRON¢. Failure to use the
proper fluid will cause hose and seal damage and fluid
leaks.
