Adaptive cruise control (ACC) allows
you to maintain a set speed and keep
the vehicle ahead of you and your
vehicle at a saf e distance without
having to use the accelerator pedal
or the brake pedal.If the vehicle ahead of you slows
down suddenly or another vehicle
cuts in f ront of your vehicle, ACC
alerts you by sounding a beeper and
displaying a message on the multi-
inf ormation display.
TheACCradarsensorinthefront
grille can detect and monitor the
distance of a vehicle up to 328 f eet
(100 meters) ahead of your vehicle.
For more inf ormation on the radar
sensor, see page .Do not use ACC under these
conditions:
In poor visibility.
In heavy traffic.
When you must slow down and
speed up repeatedly.
On winding roads.
When you enter a toll gate,
interchange, service area, parking
area, etc. In these areas, there is
no vehicle ahead of you, and ACC
would still try to accelerate to your
set speed.
In bad weather (rain, f og, snow,
etc.)
On a slippery road (f or example a
road covered with ice or snow).
As with any system, there are limits
to ACC. Inappropriate use of ACC
can result in a serious accident. Use
the brake pedal whenever necessary,
and always keep a safe distance
between your vehicle and other
vehicles.
When the vehicle ahead of you slows
down or speeds up, ACC senses the
change in distance and compensates
by accelerating or braking your
vehicle to reach the cruising speed
you previously set. The distance
between vehicles is based on your
speed: the f aster you go, the longer
the distance will be; the slower you
go, the shorter it will be.

If the vehicle ahead of you slows
down abruptly, or if another vehicle
cuts in f ront of you, a beeper sounds
and a message appears on the multi-
inf ormation display to warn you.Your vehicle f ollows the vehicle
ahead of it, keeping a constant
distance. ACC will not keep your
vehicle at a constant distance if the
vehicle ahead of you goes out of
range of your set speed.If the vehicle ahead of you slows
down and changes lanes, ACC no
longer tracks it. Your vehicle will
then return to your set speed.
In this case, decelerate your vehicle
by pressing the brake pedal, and
keep an appropriate distance f rom
the vehicle ahead.
When a vehicle ahead is within ACC
range and going at a steady speed

ACC does not work below 25 mph
(40 km/h). It cannot bring your
vehicle to a complete stop.
ACC will not sound a beeper or
display a message on the multi-
inf ormation display to warn you of
vehicles going slower than 13 mph
(20 km/h) or vehicles that are
parked. In these cases, it is up to
you to maintain a safe distance by
using the brake pedal.
ACC may not recognize
motorcycles or other small
vehicles ahead of your vehicle.ACC may react to vehicles beside
you or even a building beside you
by momentarily applying the
brakes or sounding a beeper under
conditions such as a sudden curve
or narrowing of the road, an
abrupt movement of the steering
wheel, or if you are in an unusual
position within your lane.
