Hello,

I bought my truck 5 months ago, did some hauling and I've always used the "first push" setting for exhaust brake. What's the difference between the "exhaust brake" setting and the "automatic exhaust brake" setting? I live ontop of a pretty steep hill and use the exhaust brake daily when descending the hills to save the brakes, works awesome!

 

There are two engine brake modes, manual and automatic.

Manual Engine Braking
1. Press the button to switch on manual engine braking.
2. Release the accelerator pedal to maximize engine braking.
3. Apply the brakes. The transmission downshifts to lower gears.
Note: The engine braking feature only functions when you release the accelerator.
Note: You can shift the transmission to lower gears with progressive range selection (PRS) or manual shifting independent of pressing the brakes.
Note: You can also use manual engine braking with cruise control to improve grade descent control.
Note: If your vehicle has Adaptive Cruise Control, the speed control system uses the selected engine brake mode, transmission gears, and brakes to maintain the set speed and distance to the vehicle being followed.

Automatic Engine Braking
1. Press the button twice to switch on automatic engine braking.
2. Release the accelerator or brake pedal. The system remembers your vehicle speed.
Note: This feature offers smoother, less aggressive engine braking during downhill descents. It may not apply braking if the vehicle speed is not increasing, although it will apply full engine braking force when needed to prevent acceleration. The system automatically activates the engine brake
and, if necessary, downshifts the transmission to lower gears to not exceed your vehicle's set speed when the brake or accelerator were last released.
