198 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
If the SET + button is continually pressed, the set speed
will continue to increase in 5 mph (10 km/h) increments
until the button is released. The increase in set speed is
reflected in the EVIC display.
While ACC is set, the set speed can be decreased by
pressing the SET - button.
Pressing the SET - button once will result in a 1 mph
(1 km/h) decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 mph (1 km/h).
If the SET - button is continually pressed, the set speed
will continue to decrease in 5 mph (10 km/h) increments
until the button is released. The decrease in set speed is
reflected in the EVIC display.
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 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 2 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, 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).
