360 STARTING AND OPERATING
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
i
n
strum
ent panel settings. Refer to “Getting To Know Your
Instrument Panel” for more information. The speed decre
-
ment shown is dependant on the chosen speed unit of U.S.
(mph) o
r Metric (km/h):
U.S. Speed (mph)
P
ushing the SET (-) but
ton 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
contin
ue to decrease in 5 mph decrements until the button
is rele
ased. The decrease in set speed is reflected in the
instrument cluster display.
Metric Speed (km/h)
Pushing the SET (-) but
ton 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
contin
ue 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:
W
hen you override and push the SET (+) button or SET (-)
button
s, 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 auto-
matically slow the vehicle.
T
he ACC system applies the brake down to a full stop
when fo
llowing 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 do
wn hill. 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 maintain set speed.
When driving up hill and down hill, the ACC system will
cancel if the braking temperature exceeds normal range
(overheated).
