• An abnormality occurs in the stop lamp signal.
When one of the following conditions is met, unless
the vehicle is stopped to turn the ignition switch to
the "LOCK" (OFF) position, the cruise control system
function will be suspended even if the system returns
to the normal state. Also, one of the following condi-
tions is met, a constant speed driving is cancelled
immediately. The speed limiter will be also deacti-
vated.
• Engine-ECU abnormality.

ADAPTIVE CRUISE CONTROL SYSTEM (ACC)

GENERAL INFORMATION

In addition to the conventional cruise control system
an adaptive cruise control system (ACC), which
maintains the distance from vehicle travelling in front,
has been adopted.
• *
: For the cruise control system, refer to P.17-2.
• A radar detects the distance from vehicle travel-
ling in front, and thus decelerates the vehicle by
braking if necessary to maintain the distance.
• The system attempts to maintain the distance
from vehicle travelling in front by accelerating
within the set vehicle speed by using a radar
installed in the vehicle.
NOTE: .
•
If vehicle travelling in front accelerates faster than
your vehicle's set speed, your vehicle will be
driven at your set speed.
•
If the vehicle travelling in front stops, your vehicle
also stops.
•
The system does not function if the vehicle travel-
ling in front is stationary or very slow, or much
slower than your vehicle.
•
The system may not be able to maintain the dis-
tance if the radar is contaminated, vehicles are
driven uphill or downhill repeatedly, another vehi-
cle cuts in abruptly, or a motorcycle is travelling in
front.
