  • Your vehicle owner’s manual is the driver’s best resource for crucial technical and maintenance information.
  • This manual also outlines the manufacturer’s recommended service schedule.
  • You’ll also find information on basic car care, such as how to locate and check fluids, how to inspect your vehicle’s battery, and how to replace your tires.
  • Most owner’s manuals don’t have the following information: repair instructions, DTC descriptions, and wiring diagrams.

Many vehicle owners search Google aimlessly for answers to questions like: “what type of oil does my car use” and “how do I replace my headlight bulbs.” But what they fail to realize is that the answers to these questions—and many more—are readily available in their owner’s manual. 

When it comes to taking care of your vehicle, the owner’s manual is one of the most important references to have on hand. That’s why, in recognition of the fall car care season, we’ve created a guide to help you navigate your owner’s manual to find proper information on vehicle service and upkeep. 

Your Owner’s Manual: Where to Look for Car Care Information

  • The service schedule

The Service Schedule (May Be Found in a Supplemental Booklet)

You want to take care of your car by servicing it on time, but you don’t want to waste money on unnecessary maintenance. The service schedule comes in handy because it tells you what services are due and when. For example, it mentions when:

  • Other maintenance that should be performed 

You’ll find the schedule either in the back of the owner’s manual or in a separate, supplemental booklet.

Surprisingly, many people are unaware of how much information is available in their owner’s manual⁠—and just as many get confused about what’s not included in the manual.

Here are some examples of what the document does not cover:  

How to Find a Copy Of Your Car’s Owner’s Manual Online

These days, if you lose your car’s owner’s manual, you may be able to access a digital version for free via the automaker’s website. Nearly all vehicle manufacturers provide digital owner’s manuals for models built within the last decade or two. For instance, if you have a 2015 Toyota RAV4, you can get an e-manual by going to 

But what If you have an older car or you simply want a paper manual? Usually, you can get a print copy through eBay or the dealer. 

Why Having (and Reading!) the Owner’s Manual is Important 

Nowadays, there’s no excuse not to reference your owner’s manual since digital versions are readily available online. Choosing to rely on internet search results for important questions, such as what type of oil your car takes, can lead to incorrect answers that cause big-time problems. 

So, if you want your car to last, you need to keep the owner’s manual handy—and actually read it.
