Driving
Drain all the air brake reservoirs
daily, completely to 0 kPa/psi, by
opening the draincock at the bottom
of the tanks. Close draincock after
complete draining. Air tanks
equipped with automatic moisture
ejector valves may also be drained
manually as required to maintain a
dry air system. Contact your dealer
if you are unsure of the air reservoir
locations or the draining procedure.

could damage the power steering pump.

periodically for the following:
• Spring leaf damage

• Abnormal looseness
• Damaged seals.
The following changes indicate a need to inspect and service your
vehicle:
