136 STARTING AND OPERATING
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 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 appears
in the instrument cluster display.
Distance Settings
To increase the distance setting, push the
Distance 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 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 display will
show the ACC Set With Target Detected Indicator
Light. The system will then adjust the 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.
 The system disengages Ú page 133.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
