•
If the button is continually pushed, the set speed will
continue to decrease in 5 mph decrements until the
button is released. The decrease in set speed is re-
flected in the EVIC/DID.
Metric Speed (km/h)
•
Pushing the SET - button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h.
•
If the button is continually pushed, the set speed will
continue to decrease in 10 km/h decrements until the
button is released. The decrease in set speed is re-
flected in the EVIC/DID.
NOTE:
•
When you override and push the SET + button or SET
- buttons, the new Set Speed will be the current speed
of the vehicle.
•
When you use the SET - button to decelerate, if the
engine’s braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically slow the vehicle.
•
The ACC system decelerates the vehicle to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, after two
seconds the driver will either have to push the RES
(resume) button, or apply the accelerator pedal to
reengage the ACC to the existing Set Speed.
•
The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting
may occur while climbing uphill or descending down-
hill. This is normal operation and necessary to main-
tain set speed. When driving up hill and down hill, the
ACC system will cancel if the braking temperature
exceeds normal range (overheated).
