188 STARTING AND OPERATING
Metric Speed (km/h)
Pushing the SET
(+) button once will result in a 1 km/h
increase in set speed. Each subsequent tap of the
button results in an increase of 1 km/h.
If the button is continually pushed, the set speed will
continue to increase in 10 km/h increments until the
button is released. The increase in set speed is
reflected in the instrument cluster display.
To Decrease Speed
While ACC is set, the set speed can be decreased by
pushing the SET
(-) button.
The driver's preferred units can be selected through the
instrument panel settings. Refer to “Getting To Know Your
Instrument Panel” for more information. The speed
decrement shown is dependent on the chosen speed unit
of US (mph) or Metric (km/h):
U.S. Speed (mph)
Pushing the SET (-) button once will result in a 1 mph
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 mph.
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
reflected in the instrument cluster display.
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
reflected in the instrument cluster display.
NOTE:
When you override and push the SET
(+) button or SET
(-) button, 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 suffi-
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
The ACC system applies the brake down to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, the host vehicle
will release the vehicle brakes two seconds after
coming to a full stop.
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, down shifting may
occur while climbing uphill or descending downhill. This
is normal operation and necessary to maintain set
speed. When driving up hill and down hill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
SETTING THE FOLLOWING DISTANCE IN
ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting displays in the instrument cluster display.
Distance Setting 4 Bars (Longest)
