Metric Speed (km/h)
Pushing the SET (-) button once will result in
a 1 km/h decrease in set speed. Each subse
-
quent 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 RES (+)
button or SET (-) button, the new set speed
will be the current speed of the vehicle.
When you use the SET (-) button to decel
-
erate, 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 (+) button, or
apply the accelerator pedal to reengage the
ACC to the existing set speed.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while
climbing uphill or descending downhill. This
is normal operation and necessary to main
-
tain set speed. When driving uphill and down
-
hill, the ACC system will cancel if the braking
temperature exceeds normal range (over
-
heated).
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)
Distance Setting 3 Bars (Long)
