D3 is the gear that enables you to engage the first three gears in your car (gears 1, 2, and 3) while driving. It provides an optimum driving experience for the driver while cruising around town, especially in busy environments where stop-and-go driving cannot be avoided. It also ensures the best experience while driving up or descending a hill or mountain due to its ability to engender engine braking, which is necessary for such driving.

In a situation whereby your car’s D gear has an electronic or mechanical fault resulting in a malfunctioning that prevents it from shifting gears automatically, you can alternatively drive your car by using D2 and D3. It would provide a smooth driving experience in the same way similar to a car with a manual transmission.

Meanwhile, some cars do not have D1 or D2; rather, they have (+) and (-) symbols on the gear handle. The function is similar to D1 and D2; the (+) symbol is simply for switching up the gear, and the (-) symbol is for switching down.

D3 helps your vehicle rev up when it’s at a low speed in a situation when you are trying to overtake another vehicle. It helps to boost your vehicle’s engine power to enable you to overtake satisfactorily. It is essential to understand the best gear option to engage in every situation to enjoy the best driving experience and help you ensure that your car’s components do not wear out on time, resulting in an unexpected breakdown.

The various gear position serves different purposes, since you may not easily notice their variations as you engage them. Just like D3 is faster than D2 and D1, D4 also offers a different dimension of operation while you drive. It helps your car acceleration process where D3 is not ideal. If you are also asking, “What does D3 mean in a Honda CRV?” the information above suits your question.

Therefore, it is vital to know the difference between D3 and D4 and how they deliver satisfaction in different situations to enable you to know when to engage them efficiently. Understanding their differences would help you become a better driver, as they deliver optimum driving satisfaction at different levels and different driving situations. Note that it is important to regularly check transmission fluid no matter what gear position you use when driving.

D4 vs. D3

After understanding what D3 means in an automatic transmission car, you may be asking, “What is D4 in a car?” D4 is quite different from D3; they function at different levels and deliver efficiently in varying driving situations.

D4 is used under normal driving conditions. While D3 keeps the gear limit within the first three gears (1, 2, and 3), D4 operates within the gear 1, 2, 3, and 4 limits. D4 automatically helps your car select a suitable/convenient gear for various levels of acceleration and speed while you drive. It combines the operations of D1, 2, 3, and 4, as it can switch within the range of 1 to 4.

While D3 is suitable when ascending or descending a hill and serves as the ideal gear position for a stop-and-go driving situation, D4 is most suitable for driving on a freeway (highway), especially when driving from one city to another. It has a higher speed compared to D3 and is more suitable in all conditions than D3. While D3 may not be ideal for driving on the highway, D4 can be used either within a town or on the highway. Remember, it combines the operations of D1, 2, 3, and 4.

However, cars with automatic transmissions are different from those with manual transmissions. Cars with manual transmission require that you regularly engage the gears from the lowest to the highest and vice versa; but, cars with automatic transmission have been designed to select their gear automatically from lowest to highest and vice versa.

Hence, it would be best to drive on D4 normally, whether within the city or on the highway. It would be best if you only used D3 when driving up or down a hill because of the need to maintain a slow speed. If you were also asking, “What does 2 mean in a car?” You should have known that by now.

It is best to use D4 on the highway when driving at speeds above 40 mph or 60km/h. There is usually less braking on the highway; hence D4 provides a faster speed than D3. It is better to drive at D4 when traveling outside the city than to use D3.
