Your Vehicle Owner’s Manual: Hidden Features, Warning Lights & Why You Should Read It

Apr 29, 2025 | Love My Car

Let’s be honest—most people never crack open their car’s owner’s manual. But that little book (or PDF!) in your glove compartment holds valuable insights about your vehicle, from safety features and convenience tools to mysterious dashboard lights.

Think of it as the cheat sheet to your car’s full potential—and it might just save you time, money, and frustration.

Hidden Features You Might Be Missing

Modern vehicles are packed with smart technology, but many features go unnoticed simply because we don’t take the time to explore them.

Here are some surprising tools you might discover in your owner’s manual:

  • Parking Assist – Automatic help with parallel or reverse parking

  • Forward Collision Alerts – Sensors that warn of oncoming obstacles

  • Drowsiness Detection – Monitors your driving for signs of fatigue

  • Adaptive Headlights & Wipers – Respond to weather and road conditions

  • Push-Button Start – Simplifies ignition while boosting security

  • Bag Hooks – Yes, even these! One of our clients discovered handy grocery bag hooks in their Subaru manual—no more sliding milk jugs in the back seat!

Don’t Panic Over Dashboard Warning Lights

Have you ever seen a strange symbol light up on your dashboard and wondered if your engine’s about to explode?

Before you panic, grab your owner’s manual. Many warning or indicator lights are routine, and understanding them can help you avoid unnecessary repairs.

Common Lights You Might See:

  • Check Engine Light

  • Tire Pressure Monitoring

  • Brake System Warning

  • Overdrive Indicator (O/D)

  • Traction Control or Stability Lights

💡 Pro Tip: Some lights don’t signal danger—they simply indicate a feature is active, like Overdrive (O/D), which improves fuel efficiency at highway speeds.

What Is Overdrive (O/D) and When to Use It?

Overdrive allows your transmission to shift into higher gears for better fuel economy. Most vehicles automatically enable O/D, but if you’re driving over 60 MPH and have a manual O/D switch, make sure it’s ON to maximize efficiency.

Need a Manual? Here’s Where to Look

If you’ve misplaced yours—or never got one—there are plenty of ways to access it:

Find or Order Your Owner’s Manual:

  • Visit your vehicle manufacturer’s website

  • Search on www.edmunds.com for direct links

  • Try third-party sites like eBay, Amazon, or ManualsOnline.com

  • Ask your dealership for a printed replacement

To get the correct manual, you’ll need your make, model, year, and ideally your VIN number (found on your registration or insurance card).

Final Thought

Reading your vehicle’s owner’s manual might not be as fun as binge-watching car videos on YouTube—but it’s one of the smartest things you can do to become a more informed, safe, and efficient driver.
