Maintenance and Specifications
power steering fluid and hydraulic brake fluid. Failure to observe
precautions preventing the contamination of either system with fluid
from the other will result in swelling and deterioration of rubber parts
leading to reduced brake performance and eventual brake failure.
To avoid fluid contamination, the following should always be observed:
1. Use only fluids specified (or equivalent) and properly identified.
2. Add fluids only to the following locations:
• Power steering fluid to the power steering fluid pump reservoir
• Brake fluid to the brake master cylinder
Hydraulic brakes - brake lines, hoses and fittings
Inspect these components every 4,000 miles (6,000 km).
• Check lines for kinks, dents, corrosion or rupture.
• Check hoses for abrasions, kinks, soft spots or rupture, collapse,
cracks, twists or loose frame supports. When replacing a hose, be sure
there is adequate clearance to the hose to avoid an abrasion to the
new hose.
• Examine all connections for leaks.
• Repair or replace brake line tubes, hoses or fittings as required.

Driveline parking brake

Parking brake adjustment should only be performed by a qualified
technician, and in accordance with the instructions in the service
manual.
Use wheel chocks and exercise caution when inspecting under
the vehicle. A vehicle roll-away could result in property damage,
personal injury or death.

Catalytic converter

If your diesel engine is equipped with a catalytic converter, it is
important to review the maintenance schedule to ensure proper
functioning of the catalytic converter. Also, take precautions not to
damage the catalytic converter when servicing your engine or storing
your vehicle.
Note: If your vehicle is equipped with a catalytic converter/muffler, do
not blend waste oil with Diesel fuel. Operate only on low sulfur (less
than 500 parts per million sulfur) diesel fuel with a cetane value of 45 or
higher.
