No special run-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
Do not race the engine.
While driving, keep your engine speed
(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or slow.
Varying engine speed is needed to
properly run-in the engine.
Avoid hard stops, except in emergen- cies, to allow the brakes to seat prop-
erly.
Don't let the engine idle longer than 3 minutes at one time.
Don't tow a trailer during the first 2,000 km (1,200 miles) of operation.
CAUTION
Do not let any petrol or water
enter the tank. This would make itnecessary to drain it out and tobleed the lines to avoid jamming
the injection pump and damagingthe engine.
In winter, in order to cut down incidents due to freezing, paraffinoil may be added to the fuel if the
temperature drops to below - 10°C(50°F). Never use more than20% paraffin oil.
CAUTION
Never use any fuel, whether diesel or B5 biodiesel that fails tomeet the latest petroleum indus-
try specification.
Never use any fuel additives or treatments that are not recom-mended or approved by the vehi-cle manufacturer.
