Using the Maintenance Schedule
We want to help you keep your vehicle in good working
condition. But we do not know exactly how you will
drive it. You might drive very short distances only a few
times a week. Or you might drive long distances all
the time in very hot, dusty weather. You might use your
vehicle in making deliveries. Or you might drive it to
work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You might need more
frequent checks and replacements. So please read
the following and note how you drive. If you have any
questions on how to keep your vehicle in good condition,
see your dealer/retailer.
This schedule is for vehicles that:
•
carry passengers and cargo within recommended
limits. You will find these limits on the Tire and
Loading Information label. See Loading Your
Vehicle on page 4-34.
•
are driven on reasonable road surfaces within legal
driving limits.
•
are driven off-road in the recommended manner.
See Off-Road Driving on page 4-13.
•
use the recommended fuel. See Gasoline Octane
on page 5-6.
The services in Scheduled Maintenance on page 6-4
should be performed when indicated. See Additional
Required Services on page 6-6 and Maintenance
Footnotes on page 6-7 for further information.

CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you
can be seriously injured. Do your own
maintenance work only if you have the
required know-how and the proper tools and
equipment for the job. If you have any doubt,
see your dealer/retailer to have a qualified
technician do the work. See Doing Your Own
Service Work on page 5-4.
Some maintenance services can be complex. So,
unless you are technically qualified and have the
necessary equipment, you should have your
dealer/retailer do these jobs.
