The Intelligent Cruise Control (Full Speed Range) system maintains a selected distance from the vehicle in
front of own vehicle within the speed range of 0 to 144 km/h (0 to 90 MPH) up to the set speed. The set speed
can be selected by the driver between 32 to 144 km/h (20 to 90 MPH). 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 pre-
set speed. Refer to 

CCS-29, "System Description"

.

Conventional (Fixed Speed) Cruise Control Mode

For cruising at a preset speed. Refer to 

CCS-38, "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 emer-
gency situations. Do not use cruise control except in appropriate rode and traffic conditions.

Forward Collision Warning (FCW)

FCW share the systems and components with ICC system. Refer to 

CCS-387, "System Description"
