PRECAUTIONS FOR VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
• Intelligent Cruise Control is functionally limited. This never support careless driving and low visibility (rain,
fog, etc.). Drive the vehicle safely. Keep a safe distance between vehicles by decreasing the vehicle speed
according to the driving condition etc.
• Intelligent Cruise Control never stop the vehicle automatically. Intelligent Cruise Control is automatically released, and the buzzer sounds if any vehicle ahead is not detected when the vehicle speed is approxi-
mately 35 km (21.5 MPH) or less.
• Use this system when the vehicle speed does not ex tremely change. This system may not properly function
when any vehicle cuts in, or when the vehicle ahead suddenly applies the brake. Then, the warning (buzzer
and indication) activates.
• Never use Intelligent Cruise Control in the following conditions.
- A well-trafficed road, and a tight turn. It may cause any accident because the driving does not fit to the road condition.
- A slippery road (e.g., freezing, or snowy road) The vehicle may lose the control by wheelspin.
- The vehicle drives in bad whether (rain, fog, snow etc.). The distance from the vehicle ahead is not detected pr ecisely if the whether condition is bad. Intelligent
Cruise Control is released automatically if the wiper activates in low or high speed.
- The vehicle receives bright light (sunshine etc.). The distance from the vehicle ahead is not detected pr ecisely if bright light enters in the vehicle.
- Raindrop or snow is on the sensor.
The distance from the vehicle ahead is not detected precisely if raindrop or snow attaches on the sensor.
- A steep downhill The setting vehicle speed may exceed if Intelligent Cr uise Control does not detect the vehicle ahead. The
brake may heat up in the vehicle-to-vehicle distance control mode.
- A repeated uphill and downhill Intelligent Cruise Control may not detect the vehicle ahead precisely. An accident may occur by tailgating.
- Maintaining proper vehicle distance is diff icult due to frequent acceleration/deceleration.
It may cause any accident because the driving does not fit to the road condition if keeping a proper vehicle-
to-vehicle distance is difficult.
- When entering in the highway interchange (swerving off the main line),
Unexpected accident may cause if the vehicle ahead drives slower
than the preset vehicle speed. The vehicle-to-vehicle distance con-
trol mode accelerates automatically because the vehicle ahead is
not detected on the lane if the own vehicle or the vehicle ahead
changes the lane.
• Intelligent Cruise Control does not activate to the parking vehicles, and vehicles driving extremely slower than the own vehicle. Never
hit the vehicle stopping at a tollgate, or the tail end of traffic jam.
• Intelligent Cruise Control does not activate to the vehicle edging way, and non-vehicle objects (passengers etc.).
• This function detects the reflector of the vehicle ahead. Intelligent Cruise Control may not detect the vehicle
ahead, and keep a proper vehicle-to-vehicle distance in the following conditions. Drive the vehicle according
to the driving condition.
- The vehicle ahead installs the reflector higher (trailer etc.).
- The rear of the vehicle ahead is extremely dirt.
- The vehicle ahead or vehicle on other lanes splashes water or snow on the road.
- The vehicle ahead provides dark exhaust gas. Smoke blocks the visibility.
- The vehicle ahead attaches film on the reflector. The vehicle ahead does not install the reflector. The reflec- tor is broken.
- Extremely heavy load is on the rear seat or in the cargo area.
- The vehicle drives on a repeated uphill and downhill
