STARTING AND OPERATING 175
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 An ACC Distance Is Also Set:
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 the vehicle in front. If
your vehicle follows the vehicle in front 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 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 Settings
To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving
vehicle is detected in the same lane, the
instrument cluster displays the ACC Set With
Target Light. The system will then adjust vehicle
speed automatically to maintain the distance
setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed
The vehicle ahead moves out of your lane or
view of the sensor
The distance setting is changed
