GOOD DRIVING HABITS

Weight Ratings

Do not overload the vehicle. The gross vehicle weight rating (GVWR) and
gross axle weight ratings (GAWR's) for a given model may vary due to the
tires, wheels/rims, suspensions, axles and/or frame of a specific vehicle. For
safety and durability reasons, do not exceed the GVWR and GAWR's listed on
your vehicle's Safety Certification Label.

Instruments

Glance at the instruments frequently. When problems develop, take prompt
steps to correct them.

Shutting Down the Engine

After a hard run, allow the engine to idle three minutes before shutdown to
stabilize the temperature of all engine parts. Quick shutdowns can cause
engine damage and prevent the turbocharger from being properly lubricated.
For additional options, see "Shutting Down the Engine", page 174.

General Observation

Make it a habit at stops to walk around your truck and look for fuel, oil and
coolant leaks. Also check the condition of tires, wheel nuts, springs and lights.
Stop trouble before it stops you!
