System Description

INFOID:0000000005234677

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.
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.
