Apa itu Overdrive pada Kendaraan? Ini Fungsi dan Tipsnya

When buying a car, car manufacturers certainly provide several important features that make it easier for drivers, including overdrive. So what is meant by overdrive? What are its functions? And how to use this feature correctly? Before answering these questions, let's first understand what is meant by overdrive in cars. Overdrive is a car feature in the form of a lever or button that optimizes fuel efficiency when the car is at high speed. To understand it further, let's take a look at the following explanation.

What is Overdrive?

Overdrive is a term used to describe a vehicle's transmission gear with a higher gear ratio compared to engine speed. If you are using an automatic car with a 4-speed transmission, then the engine speed is the same as the ratio in gear 3. So, when you use gear 4, the rotational ratio is greater than the engine speed, hence it is called overdrive. The overdrive feature can make the car more responsive when overtaking other vehicles on the road. 

Functions of Overdrive in Cars

There are several functions of car overdrive that you need to know. Here are the complete functions.

1. Limiting the acceleration of gear shifting

The main function of overdrive is to limit the acceleration system when shifting the car's gears. This way, the car's transmission does not use all available gears when operating. For example: if your car has a 4-speed transmission, when you use the overdrive feature, the acceleration can only be done up to the third gear ratio.

2. Helping to conquer hills or overtake other vehicles 

The next function, overdrive can make it easier for drivers to conquer hills and overtake other vehicles. When the overdrive feature is pressed, overdrive becomes inactive. Meanwhile, when the overdrive feature or button is not pressed, overdrive becomes active. 

Tips for Correctly Using the Overdrive Feature

Here are some tips you can follow when you want to use the car's overdrive feature. Here are the right tips.

1. Use when overtaking or going uphill

When you want to overtake (pass another vehicle), you can use the overdrive feature. This feature can also be used when you want to go over a hill that is not steep. In this condition, your car needs better power, so the overdrive feature will help your car get the necessary power. However, if the road is steep, you need to shift to a lower gear.

To activate the overdrive feature is easy, you just need to press the O/D button or shift the lever to the O/D position. You need to remember, O/D or overdrive will be in a non-functional (off) condition if the indicator light is on. Meanwhile, O/D will function (on) when the indicator light is off. Immediately deactivate O/D when you no longer need it, or when the car's speed is below 60 km/h.

2. Avoid using overdrive when driving at normal speeds

The second tip, you should not use the overdrive feature when the car is driving on smooth roads or when the car is moving at normal speeds. This will certainly hinder the car's speed, as the car may stutter. In addition, improper use of the overdrive feature can affect the lifespan of the car's transmission system components

These are some tips you can follow when you want to use the car's overdrive feature. Don't forget to always perform maintenance on car components at a professional workshop like Daihatsu workshop.
