How To Calculate The Correct Service Intervals - Toyota Prius Warranty & Service Handbook

How to Calculate the Correct Service Intervals

Your Prius must be serviced according to the Maintenance Schedule in
this book. Service intervals are for a given distance or period of time,
whichever occurs first.
Even if you don't drive far enough to cover the distance between
service intervals, your Prius should still be serviced according to the
time period shown on the schedule. Regular maintenance is vital to
maintain the performance and longevity of your Prius.
Lubricants and other items deteriorate over time as well as distance.
Old or contaminated oil doesn't provide the engine with full protection
and could cause serious engine damage.
Additional Service Requirements
How and where you drive your Prius determines the service
requirements as much as the time or distance travelled. For example, if
you are regularly towing heavy loads or driving in rough conditions,
then more frequent maintenance is necessary, refer to Additional
Service Requirements in this Section. The Service Advisor at your
Toyota Prius Service Centre can best advise you on the maintenance
requirements, to suit your driving conditions.
MAINTENANCE OF YOUR TOYOTA
Break-in Period Oil Change
Your new Prius is manufactured to precision tolerances and rigorously
checked and filled with high quality lubricants at the factory; as such the
oil and filter does not need to be changed until the first service.
Oil Thickening
Oil thickening is a phenomenon which occurs when particles of unburnt
fuel and combustion by-products cause a build-up of carbon (soot) in
the engine oil forming a jelly type substance. It can cause serious engine
damage through oil starvation. It is essential that the engine oil is
changed according to the Maintenance Schedule in this Section, at
either the time or distance specified.
