Diesel Exhaust Brake Indicators

Diesel Exhaust Brake

These are Diesel Exhaust Brake Indicator symbols. One of the indicators will be seen when the Diesel Exhaust Brake has been activated and is in full strength mode (first image) or in Automatic (AUTO) mode (second, third and fourth images).

• Before continuing, are you sure this is your symbol?? If yes, then read on below.
• Otherwise, you can return to our main Picture Symbols page and scan again!

The appearance is that of a less than sign or a sideways V with wavy lines at one end, all inside a circle inside brackets. The latter is a standard part of many symbols associated with brakes.

The feature supplies negative or braking torque from the engine. Typically, the engine braking is used for, but not limited to, vehicle towing applications where additional vehicle braking can be achieved by the internal engine power. This preserves the vehicle’s mechanical brakes.

The exhaust brake feature will function when the driver toggles it on by pushing the exhaust brake button until the indicator is seen. Normal (Full Strength) exhaust brake mode is indicated by the yellow/amber/orange Exhaust Brake Indicator, as is the green version.

Turned Off

Automatic or Smart Exhaust Brake can be enabled by pushing the exhaust brake button again anytime after the normal Full Exhaust Brake has been turned on. The Exhaust Brake Indicator will change from yellow/amber to green when Automatic Smart Exhaust Brake is enabled. Pushing the exhaust brake button again will toggle the exhaust brake mode to off.
