Engine Brake
The engine brake is controlled by the lever position
(as shown in
Fig. 17.2). At the top position, the en-
gine brake is off, and at the three lower positions, the
engine brake is on and the intensity (low, medium,
high) increases with each step down. For more infor-
mation about using the engine brake, see
Chapter 15.
NOTE: Using the engine brake with cruise con-
trol can be used to activate Descent Control
Mode or Deceleration Mode. For more informa-
tion, see "Cruise Control" in
Chapter 7.
