10 Simple Step-by-step Guidelines on How to Use Engine Brake in Automatic Transmission

Step 1: Understand the Function

First, understand that an engine brake, also known as a compression brake or exhaust brake, helps slow down a vehicle by using the engine’s resistance to reduce speed rather than relying solely on the vehicle’s brakes. You can achieve this by releasing the accelerator pedal while driving.

Engine Braking Works Best in Lower Gears

It’s important to note that engine braking works best in lower gears and at higher speeds. The higher the engine speed, the more effective the engine brake will be. You can experiment with different gears and speeds to find the optimal engine braking for your vehicle.

Step 2: Locate the Gear Selector

Identify the gear selector in your vehicle, typically located on the center console or steering column. It will have the following settings: P (park), R (reverse), N (neutral), D (drive), and L (low gear). The low-gear setting is where you can activate engine braking. Not all automatic vehicles have a low gear mode; some may require you to manually shift into a lower gear.

You can refer to your vehicle’s owner’s manual for more information on the gear selector and its functions. But in general, the lower the gear, the more engine braking you will experience. It’s best to use this feature when driving on steep descents or in hazardous weather conditions.

Step 3: Engage Overdrive (if equipped)

Vehicle is Equipped With Overdrive

If your vehicle is equipped with overdrive, ensure it is engaged. Overdrive can help provide additional engine braking when descending hills or slowing down. However, make sure to disengage overdrive before engaging lower gears. It is usually a button located on the gear selector or steering wheel.

You can also refer to your owner’s manual for more information on overdrive and its functions. The overdrive light should turn off when it is disengaged. But keep in mind that not all vehicles have overdrive. It’s best to check your owner’s manual if you are unsure.

Step 4: Downshift Manually (if equipped)

If your vehicle has a manual shifting mode or paddle shifters, manually downshift to a lower gear to increase engine braking. This allows the engine to rev higher and provide more resistance, slowing down the vehicle. You can usually downshift by pressing the “+” or “-” buttons on the gear selector or steering wheel.

You can also manually downshift by moving the gear selector from D (drive) to  L (low gear). It’s essential to note that not all automatic vehicles have this feature. You can refer to your owner’s manual for more information on manual shifting mode and its functions.

Step 5: Use Tow/Haul Mode (if equipped)

Some automatic transmission vehicles have a tow/haul mode, which adjusts shift points and engine braking to provide better control when towing heavy loads or descending steep grades. Activate tow/haul mode if available. You can usually find this button on the gear selector or steering wheel. Refer to your owner’s manual for more information on tow/haul mode.

Vehicles Have a Tow/Haul Mode

But keep in mind that not all vehicles have this feature. The tow/haul light should turn on when activated. You can refer to your owner’s manual for more information on tow/haul mode and its functions. But in general, it is recommended to use this mode when driving downhill and carrying a heavy load.

Step 6: Monitor Engine RPM

While driving, monitor the engine’s RPM (revolutions per minute) gauge. When descending a hill or approaching a stop, you can manually downshift to keep the engine RPM higher, maximizing engine braking. You can also release the accelerator pedal to let the transmission automatically downshift and slow down the vehicle. Be careful not to over-rev the engine, as this can cause damage.

Otherwise, it is a safe and effective way to control your vehicle’s speed without using the brakes. Then, when you need to gain speed again, simply press the accelerator pedal or upshift to a higher gear.

Step 7: Anticipate Stops and Descents

Anticipate stops, intersections, or downhill grades ahead of time. By planning ahead, you can adjust your speed and use engine braking more effectively to slow down without relying heavily on the brakes. It will also help you avoid sudden and frequent braking, which can cause wear and tear on the brakes and decrease their lifespan. You can also use this technique to maintain a steady speed while driving on hilly or winding roads, providing more control and stability. But remember to always use caution and follow traffic laws while driving.

Step 8: Apply Gentle Pressure to the Gas Pedal

When using engine braking, apply gentle pressure to the gas pedal as needed to maintain control of the vehicle’s speed. This helps prevent the vehicle from slowing down too abruptly. It also gives you more control of the vehicle and prevents it from stalling. You can also use the gas pedal to manually downshift instead of using the gear selector, which can be useful in certain situations.

Apply Gentle Pressure to the Gas Pedal

It’s essential to be gentle with the gas pedal to avoid over-revving the engine and causing damage. However, if needed, you can also quickly release the accelerator pedal to activate engine braking.

Step 9: Monitor Vehicle Speed

Continuously monitor your vehicle’s speed and adjust your use of engine braking accordingly. If you need to slow down more quickly, you may need to apply the brakes in addition to using engine braking. You can also use engine braking to maintain a steady speed while driving downhill, preventing the vehicle from gaining too much speed and potentially causing loss of control.

It’s essential to always be aware of your surroundings and adjust your driving accordingly. Thus, using engine braking correctly can help improve your driving experience and increase safety on the road. With practice, you can become more comfortable and confident in using this technique to control your vehicle’s speed without relying solely on the brakes.
