SYSTEM
In the conventional (fixed speed) cruise control mode,
a warning chime does not sound to warn driver if own
vehicle are too close to the vehicle ahead, as neither the presence of the vehicle ahead nor the vehicle-to-
vehicle distance is detected.
OPERATION DESCRIPTION
To turn ON the conventional (fixed speed) cruise cont rol mode, push and hold the MAIN switch for longer than
approximately 1.5 seconds when ICC system is OFF.
When pushing the MAIN switch ON, the ICC system display and the MAIN switch indicator are displayed on
the information display.
After hold the MAIN switch ON for longer than approxim ately 1.5 seconds, the ICC system display goes out.
The MAIN switch indicator stays lit and brings the system to standby state.
NOTE:
To turn on the vehicle-to-vehicle distance control mode again, turn OFF the system and quickly push (less
than 1.5 seconds) the MAIN switch.
When the DCA system is ON, the conventional (fixed speed) cruise control mode cannot be turned on even
though the MAIN switch is pushed and held.
To turn ON the conventional (fixed speed) cruise control mode, turn OFF the DCA system. Refer to DAS-68,
"System Description".
ADAS control unit performs the control as per the following:
Set Condition
When the system is under a standby state and the vehi cle speed is between approximately 40 km/h (25 MPH)
and 144 km/h (90 MPH), pushing the SET/COAST switch will start system control.
If the system is canceled by conditions 1-6 below, the sy stem will resume control at the last set cruising speed
by pushing the RESUME/ACCELERATE switch.
Cancel conditions1. When CANCEL switch is pressed.
2. When brake pedal depressed.
3. When the vehicle speed falls below approximately 32 km/h (20 MPH).
4. When the vehicle slows down more than 13 km/h (8 MPH) below the set speed.
5. When the selector lever is not in the “D” position or manual mode.
6. When the parking brakes are applied.
7. When the MAIN switch is turned OFF.
8. When VDC (including the TCS) operates.
9. When a wheel slips.
10. When the system malfunction occurs.
Constant
speed Comparing the set vehicle speed with the current vehicle speed, transmits the command to ECM via CAN communication
to reach the set vehicle speed, and controls the electronic throttle control actuator.

NOTE:
The display of the DCA system is given priority when the DCA system is ON in a standby mode. (The set vehi-
cle speed indicator, set distance indicator, and own vehicle indicator are not displayed).
APPROACH WARNING DISPLAY
If own vehicle comes closer to a vehicle ahead due to rapi d deceleration of that vehicle or if another vehicle
cuts in, the system warns the driver with the chim e and ICC system display. Decelerate by depressing the
brake pedal to maintain a safe vehicle distance if:
The chime sounds.
The vehicle ahead detection indicator and set distance indicator blink.
The warning chime may not sound in some cases when there is a short distance between vehicles. Some
examples are:
When the vehicles are traveling at the same s peed and the distance between vehicles is not changing.
When the vehicle ahead is traveling faster and the distance between vehicles is increasing.
When a vehicle cuts in at near own vehicle.
The warning chime will not sound when own vehicle approac hes vehicles that are parked or moving slowly.
The warning chime will not sound when the accele rator pedal is depressed, overriding the system.
The approach warning chime may sound and the system disp lay may blink when the ICC sensor detects some
reflectors which are fitted on vehicles in other lanes or on the side of the road.
This may cause the ICC system to dec elerate or accelerate the vehicle.
The ICC sensor may detect these reflectors when the vehicle is driven on winding roads, hilly roads or when
entering or exiting a curve.
The ICC sensor may also detect reflectors on narrow roads or in road construction zones.
In these cases driver will have to manually control the proper distance ahead of own vehicle.
Also, the sensor sensitivity can be affected by vehicle operation (steering maneuver or driving position in the
lane) or traffic or vehicle condition (for example, if a vehicle is being driven with some damage).
