DESCRIPTION
OutlineINFOID:0000000001328805
The Intelligent Cruise Control (ICC) system automatically maintains a selected distance from the vehicle
ahead according to that vehicle's speed, or at the set speed, if the road ahead is clear.
The ICC function has two cruise control modes and brake assist (with preview function).
VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
With vehicle-to-vehicle distance control mode, the driver can maintain the same speed as other vehicles with-
out the constant need to adjust the set speed as the driver would with a normal cruise control system.
The system is intended to enhance the operation of the vehicle when following the vehicle traveling in the
same lane and direction.
If the distance sensor detects a sl ower moving vehicle ahead, the system wil l reduce speed so that the vehicle
ahead can be followed at the selected distance.
The system automatically controls the throttle and applie s the brakes (up to 25% of vehicle braking power) if
necessary.
The detection range of the sensor is approximately 120 m (390 ft) ahead.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Conventional (fixed speed) cruise contro l mode is cruising at preset speeds.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.
BRAKE ASSIST (WITH PREVIEW FUNCTION)
When the force applied to brake pedal exceeds a certain level, the Brake Assist is activated and generates a
greater braking force than that of a convent ional brake booster even with light pedal force.
When the Preview Function identifies the need to apply the sudden brake by sensing the vehicle ahead in the
same lane and the distance and relative speed from it, it applies the brake pre-pressure before driver depress
the brake pedal and improves brake re sponse by reducing its free play.
Refer to Owner's Manual for BRAKE ASSIST (W ITH PREVIEW FUNCTION) operating instructions.
