Metric Speed (km/h)
 Pushing the SET (+), or SET (-) button once will result in
a 1 km/h speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 km/h.
 If the button is continually pushed, the set speed will
continue to adjust in 10 km/h increments until the
button is released. The new set speed is reflected in
the instrument cluster display.
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 ACC Is Active
 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
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 maintain set
speed. When driving uphill and downhill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
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 will show in the instrument cluster
display.
Distance Settings
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)
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).
STARTING AND OPERATING
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 a slower moving vehicle is detected in the same lane,
the instrument cluster display will show the ACC Set With
Target Detected 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.
 The system disengages page 107.
Ú
The maximum braking applied by ACC is limited; however,
the driver can always apply the brakes manually, if
necessary.
NOTE:
The brake lights will illuminate whenever the ACC system
applies the brakes.
A Proximity Warning will alert the driver if ACC predicts that
its maximum braking level is not sufficient to maintain the
set distance. If this occurs, a visual alert "BRAKE!" will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
force.
