The radar sensor for ACC is shared
with the collision mitigation brake
system (CMBS). For more
inf ormation on the radar sensor, see
page . For more inf ormation on
CMBS, see page .
Adaptive cruise control (ACC)
consists of a radar sensor in the
f ront grille, the ACC buttons on the
steering wheel, and the ACC

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 ACC is cancelled by any these
conditions, wait until the condition
improves, then press the RES/
ACCEL button to restore ACC.
When you do this, the vehicle will
resume its set cruising speed.
If you turn the ignition switch to the
ACCESSORY (I) or LOCK (0)
position af ter ACC was automatically
cancelled, the set speed is erased,
and you must enter it again (see
page ).
Poor weather (rain, f og, snow, etc.)
When the radar sensor in the front
grille gets dirty.
The vehicle ahead of you cannot
be detected.
An abnormal tire condition is
detected, or the tires are skidding.
When ACC is automatically canceled,
the beeper sounds about 1 second,
and an ACC OFF message appears
