CONTROLS AND INSTRUMENTS
When Returning to Cruise Control Driving
If you have canceled cruise control under the following conditions, you can return to
the cruise control driving condition before cancellation when you operate and release
the cruise control resume switch. The moment the resume switch is released, the
cruise control set indicator light comes on.
• When depressing the brake pedal.
• When applying the exhaust brake.
• When shifting gears.
• When operating the cruise control cancel switch.
Automatic activation of the auxiliary brake (exhaust brake) during cruise control driving
suppresses an increase in the speed on a downhill slope, decreasing the need for the
driver to apply the regular brake pedal.
CAUTION
• The maximum slope angle at which the system can control the vehicle speed
increase is different depending on the load the vehicle is carrying.
Automatic Activation and Automatic Release 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.
