Applying the Brakes Manually
If the driver Is aware of a posslble threatening situation, you should take all necessary and Immediate actions; never wait for the VADA system to intervene. Safe operation of the vehicle is the responsibility of the driver. H the driver applies the brakes, cruise control wfll automalically disengage, and there will not be a VADA intervention If the driver applies more than two-thirds brake application.
Approaching Slower Moving
When approaching a much slower­ moving vehtcle ahead, the driver should anticipate this and begin applying the vehicle's brakes early and not wait for the VADA system to lniervene.

The VADA system should have significantly less false alerts lhan earlier systems. Radar technology Is not perfect, however, and false alerts sometimes occur. If false alerts occur too
Impact Alert Warning
Ignoring the Impact Alert warning from the V/>£JA can lead to death, personal Injury or vehlcle damage.
The Impact Alert (IA) is the mos! severe warning Issued by the system. The IA Warning Indicates Iha! the driver should apply more braking force immediately. The Driver Information Display (DID) provides several visual and audible alerts.
The instrument cluster illumlnates red light emitting diodes (LEDs), and a pop­ up displays requesting the driver to act. Also, a continuous tone is sounded.

Potential False Warnings
Also, when an Impact Alert occurs, a "Heads Up" warning Is displayed as a red line reflected in the windshield. The red line lllumlnates from the lop of the dash.
When the IA activates, take evasive acUon by applying more braking power and/or steering clear of the vehicle ahead lo avoid a potential collision.
If an impact alert occurs and driver intervention Is required, a continuous audible sound and various warning screens display. The screen diSplayed and audible aten level are dictated by the closeness of the vehicle/object.

Operational Notes
When passing a vehicle or changing lanes, the vehicle ls no longer tracked by the system.
When lhe vehicle ahead is out of sensor range and no other vehicle present. after a short safety delay occurs. Then 1he system accelerates to the last stored set speed.
