Using the Maintenance Schedule
We want to help keep this 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 the 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 the vehicle in good
condition, see your dealer/retailer.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
