What is the “O/D Off” button on my Automatic Car?
Most drivers who drive an automatic vehicle probably have no idea what the O/D Off button does. The good news is, it’s one of the easiest buttons to learn about and understand how to use properly in your car. This article explains everything you need to know about the O/D Off button on your automatic vehicle, including why it’s there and how to use it properly when you need to use it. We hope this helps you make better decisions about how you drive in the future!
What is the “O/D Off” button on my automatic car?
The OD off button allows for manual gear selection in some vehicles equipped with automatic transmissions. When a car with an automatic transmission reaches cruising speed, pushing that button will enable you to select from three gears (known as L, 2, and 3). This helps to eliminate jerky gear shifts by your vehicle.

Why O/D Off is important
O/D (Overdrive) can confuse some drivers because it has two different functions. First, O/D allows you to manually shift from your current gear ratio to a lower one, and it’s used to enhance fuel economy when driving at high speeds. Your vehicle’s speed-sensitive transmission constantly monitors its efficiency by checking information from all its sensors; once it sees that you’re going at a consistent pace, it automatically shifts down through your gears. This keeps you in optimal equipment for your specific speed, which improves fuel economy by up to 10 percent.
How O/D OFF can save you time, money, and accidents
You’ve probably never had to use your OD off feature if you drive an automatic vehicle. That might change if you take a trip down a hill, however. Automatic transmissions shift gears automatically (which is why they’re called automatics). Still, they can move back and forth between gears when they encounter too steep of a decline or incline, losing control over your vehicle.
This can be dangerous both for you and other drivers around you—or anyone who may wander into your path. At the same time, you’re temporarily stuck at 30 miles per hour. The OD off feature will keep your transmission from shifting into neutral when going downhill. It may prevent others from stealing your car.
When to use it
Should you need to drive more slowly than usual, depress the accelerator and turn off the cruise control. While you still have a foot on the gas pedal, push in and hold down your cruise control’s O/D Off button.
The word Off will appear as soon as it’s activated, which means your cruise control is now disengaged. As long as your foot stays pressed to the gas pedal, your vehicle should remain at its current speed—you won’t accelerate or decelerate until you let go of that pedal. It’s not for situations where you want to slow down gradually; if that’s what you’re looking for, pull back gently on your accelerator.
Overuse of O/D OFF
Many drivers understand that Overdrive (or O/D) refers to an overdrive gear or a setting that helps make it easier to accelerate in traffic or drive up a hill. They may even know that if they push their O/D switch, their vehicle will become more fuel-efficient and get better gas mileage.
However, most drivers don’t realize how quickly they can use up all their transmission fluid by driving with their Overdrive off. So when you put your car into Drive, it automatically sets your transmission into Overdrive. It does so because that makes it more fuel-efficient and easy to drive.
Can O/D OFF hurt your car?
When drivers talk about shifting to or from Overdrive or Driving, they refer to their vehicle’s specific gear. When you push a shift up or down, you are changing gears and advancing (up) or slowing (down) your engine speed. Typically, automatic transmission only has one forward gear: Overdrive. When your engine goes faster than its normal speed, it shifts into Overdrive. On many cars, pushing shift downturns off Overdrive and returns it to its normal setting for driving around town.
Turning off Overdrive can help you get better gas mileage because it slows your engine speed back down to normal levels. However, if you turn off Overdrive while going too fast for conditions, your car could start shaking as it adjusts to lower speeds.
You may also hear a loud clunking noise. If you feel like something is wrong with your vehicle after turning off O/D OFF, stop immediately and check out what’s going on under the hood before continuing with your Drive.
If your engine dies with O/D OFF, what should you do?
Suppose your engine dies while driving with O/D OFF. In that case, you’re going to be pulling over and attempting to restart your vehicle—and that’s okay. Remember: You still have a gearbox, so don’t worry about trying to drive home in 1st gear!
If you’re traveling at highway speeds, it may be safest to pull over in a safe spot and wait until you feel confident enough to continue driving without worrying about your engine dying again.
Also, keep in mind that rolling back isn’t an option if you end up parking on an incline (or downhill) after all of these failures. You need your brakes and steering for safety reasons and because they’re required for shifting gears!
Since driving an automobile can be dangerous to you and others if done improperly, it’s important to know what each control does. Don’t risk hurting yourself or anyone else by playing with unfamiliar rules.
The OD offsetting in your car stands for Overdrive off. This was a popular feature of vehicles back in the day, but it’s not used very often anymore. OD off will keep your transmission from shifting out of Overdrive while cruising down a highway or flat road when driving an automatic transmission car. Overdrive was created to save gas mileage and is generally found around fourth gear on newer cars.
