STARTING AND OPERATING 175
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 15 seconds at a time.
Wait 10 to 15 seconds before trying again.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the recom-
mended viscosity and quality grades, refer to “Dealer
Service” in “Servicing And Maintenance”.

Turbo Charger “Cool Down”
This vehicle is equipped with an after-run pump to cool the
turbocharger after the engine is shut off. Depending on the
type of driving and the amount of cargo, the pump will run
for up to 10 minutes after the engine has been shut off to
circulate coolant through the turbocharger.
CAUTION!
Although the pump is rubber-mounted for quiet operation,
it is normal to hear it running during this time.
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
ENGINE BREAK-IN RECOMMENDATIONS
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and not
interpreted as a problem.
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
