DESCRIPTION

Intelligent Cruise Control

The Intelligent Cruise Control (ICC) system maintains a selected distance from the vehicle ahead within set speeds.

The driver can select the set speeds.

The vehicle travels at a set speed when the road ahead is clear.

The ICC system can be set to one of two cruise control modes:

CAUTION:

Never set the cruise speed exceeding the posted speed limit.

Vehicle-to-vehicle Distance Control Mode

For maintaining a selected distance between own vehicle and the vehicle in front of own vehicle up to the preset speed. Refer to System Description .

Conventional (Fixed Speed) Cruise Control Mode

For cruising at a preset speed. Refer to System Description .

NOTE: In the Conventional (Fixed Speed) Cruise Control Mode, a warning chime will not sound to warn driver if own vehicle are too close to the vehicle ahead.

WARNING: Always drive carefully and attentively when using either cruise control mode. To avoid serious injury or death, do not rely on the system to prevent accidents or to control the vehicle's speed in emergency situations. Do not use cruise control except in appropriate rode and traffic conditions.

Distance Control Assist (DCA) System

DCA share the systems and components with ICC system. Refer to System Description .

Predictive Forward Collision Warning (PFCW) System

PFCW share the systems and components with ICC system. Refer to System Description .

Forward Emergency Brake (FEB) System

FEB system share the systems and components with ICC system. Refer to System Description .
