Using the Maintenance Schedule
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 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 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 questions on how to keep the vehicle in good condition, see your dealer.
This part tells you the maintenance services that should be done and when to schedule them.
When you go to your dealer for service, trained and supported service people will perform the work using genuine parts.
The proper fluids and lubricants to use are listed in Part D. Make sure whoever services the vehicle uses these. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle.
These schedules are for vehicles that:
- carry passengers and cargo within recommended limits on the Tire and Loading Information label. See Loading the Vehicle.
- are driven on reasonable road surfaces within legal driving limits.
- use the recommended fuel. See Gasoline Octane.
