48 inches deep

How does grade braking work in normal mode?
For grade braking to activate it requires the driver to apply steady brake pedal pressure to maintain desired speed while driving on a downhill grade. The vehicle’s modules monitor the amount of brake pedal apply, vehicle deceleration rates, and other factors to determine if normal mode powertrain grade braking is necessary.
What does a jake brake on a semi trailer do?
What is a Jake brake? “Jake Brake” refers to compression release engine brakes. A feature on large diesel-powered vehicles like semi-trailers, it works by releasing the compressed air in the engine via the exhaust valves to quickly reduce speed, resulting in a loud noise.
