Do not approach the exhaust system or surrounding areas without allowing adequate time for the system to cool down. Failure to do so could result in serious burns to the skin. Diesel Exhaust Fluid (DEF) Gauge create a braking effect on the drive wheels. Because it can help keep your vehicle’s brakes from overheating, it can save wear and tear on the service brakes. However, the engine compression or exhaust brake is not an emergency brake or the primary vehicle brake.
WARNING Do not operate the engine compres- sion brake when driving/operating your vehicle bobtail or with a loaded or un- loaded trailer on road surfaces with poor traction (wet, icy, or snow cov- ered roads) or in heavy traffic. There may not be enough weight on the rear axle to provide traction. Braking caused by the normal operation of the engine compression brake could cause you to lose control of the vehi- cle, resulting in an injury accident. Make sure the engine brake is switch- ed "OFF" when bobtailing or with an unloaded trailer. Failure to comply may result in death, personal injury, equip- ment or property damage.
