If you’re referring to a common hidden car feature, one of the best-known examples is the small arrow next to the fuel-pump icon on your dashboard.
⛽ The little arrow has a purpose
Look at the fuel gauge on your dashboard. Many cars have a tiny arrow pointing left or right beside the fuel-pump symbol.
That arrow tells you which side of the car the fuel filler door is on.
So if you’re driving an unfamiliar car or a rental and can’t remember which side the fuel cap is on, just check the arrow.
A few other “hidden” features
Depending on the vehicle, you may also have:
A fuel-door emergency release inside the trunk or cargo area.
A hidden physical key inside your key fob for unlocking the door if the battery dies.
A trunk-release mechanism that can be used from inside the trunk in an emergency.
Automatic headlight or wiper settings that may already be available but aren’t enabled.
A tire-pressure monitoring display that can show individual tire pressures on some models.
The exact features vary considerably by make, model, and year.
If you tell me your car’s make, model, and year, I can list the lesser-known features it actually has.
