Models with Auxiliary Brake-coordinated Cruise Control
This type of cruise control system automatically engages the auxiliary braking function
(exhaust brake) while it is in use to limit the increase in speed on a downhill slope.
This helps lighten the driver's workload (reducing the need to use the brake pedal to
prevent vehicle speed increase).
CAUTION
• The maximum slope angle at which the system can prevent the vehicle speed
increase is different depending on the load the vehicle is carrying.
Automatic Engagement and Disengagement of Auxiliary Brake
• The auxiliary brake is engaged when the vehicle speed exceeds the set speed on
a downhill slope.
• The auxiliary brake is disengaged when the vehicle slows down close to the set
speed.
