INTELLIGENT BRAKE ASSIST


System Description


FUNCTION DESCRIPTION
Intelligent Brake Assist (IBA) system warns the driver by a warning lamp and chime when there is a risk of a collision with the vehicle ahead in the traveling lane and the driver must take avoidance action immediately.
The system helps reduce the rear-end collision speed by applying the brakes when it judges a collision can not be avoided.

CAUTION:
The IBA system is a not collision avoidance system. It is the driver's responsibility to stay alert, drive safely and be in control of the vehicle at all times. As there is a performance limit, it may not provide a warning or brake in certain conditions.

NOTE:
- The IBA system shares component parts and diagnosis with the ICC (Intelligent Cruise Control) system.
New parts added to the IBA system is the IBA OFF indicator lamp in the combination meter and the IBA OFF switch on the inside instrument driver lower panel.
- The ICC sensor integrated unit shares the parts with the ICC, but the IBA system will operate even when the
ICC system is turned to OFF.

OPERATION DESCRIPTION
The IBA system uses a distance sensor located below the front bumper to measure the distance to a vehicle ahead. When the system judges that the distance gets shorter, the vehicle ahead detection indicator lamp on the combination meter blinks and the warning chime sounds.
To turn the system off/on, push and hold the IBA OFF switch after starting the engine for more than 1 second.

NOTE:
- The system on/off condition will be memorized even if the ignition switch turns OFF.
- The IBA system operates under the following conditions.
- The IBA system will function when the vehicle is driven at speeds of approximately 15 km/h (10 MPH) and above, and when the vehicle's speed is approximately 15 km/h (10 MPH) faster than that of the vehicle ahead.
