The smart cruise control system may have limits to detect distance to the vehicle ahead due to road and traffic conditions. |
| • |
On curves or inclines/declines |
| - |
On curves or inclines/declines, the smart cruise control
system may not detect a moving vehicle in your lane, and then your
vehicle may accelerate to the set speed directly. Also, the vehicle
speed may slow down abruptly when the vehicle ahead is recognized.
Select the appropriate set speed on curves or inclines/declines and
control the vehicle speed by applying the brake pedal if necessary. |
| - |
Your vehicle speed can be reduced due to a vehicle in the
adjacent lane. Apply the accelerator pedal and select the appropriate
set speed. Check to be sure that the road conditions permit. 
|
| - |
A vehicle which moves into your lane from an adjacent lane
cannot be recognized by the sensor until it is in the sensor's detection
range. |
| - |
Be always cautious because a vehicle which suddenly moves into your lane can be recognized late by the sensor. |
| - |
If the vehicle which moves into your lane is slower than your
vehicle, the speed may decrease to maintain the distance to the vehicle
ahead. |
| - |
If the vehicle which moves into your lane is faster than your
vehicle, your vehicle will maintain the selected speed even the vehicle
is in the sensor's detection range. 
|
| - |
Even though a vehicle is in the same lane, a vehicle which is
out of the sensor’s detection range cannot be recognized by the
sensor.
1) Small vehicle such as motorcycle, bicycle and cultivator
2) A vehicle offset to one side
3) A slow-moving vehicle or sudden-decelerating vehicle
4) A stopped vehicle
5) A vehicle with small rear profile such as trailer with no loads 
|
| - |
In this following situation, the front vehicle can’t be
recognized correctly so control the vehicle speed by applying the brake
pedal or accelerator pedal if necessary.
1) When the vehicle is pointing upwards due to overloading in the trunk
2) While making turns by steering
3) When driving to one side of the lane
4) When driving on narrow lanes or on curves
|
| • |
If the smart cruise control is left on (CRUISE indicator
light ON), the smart cruise control can be switched on accidentally.
Keep the smart cruise control system off (CRUISE indicator light OFF)
when the smart cruise control is not in use, to avoid inadvertently
setting a speed. |
| • |
Observe a regulation speed on road when setting the cruise speed. |
| • |
Do not use the cruise control when it maynot be safe to keep the car at a constant speed : |
| - |
Driving in heavy or varying speed traffic |
| - |
On slippery (rainy, icy or snow-covered) roads |
| • |
Pay particular attention to the driving conditions whenever using the smart cruise control system. |
| • |
The vehicle cannot be stopped by using the smart cruise
control system. If emergency stop is necessary, you should apply the
brakes. |
| • |
Keep the safety distance according to road conditions and
vehicle speed. If the following distance is too close at a high speed
driving, it is dangerous. |
| • |
The smart cruise control system can not recognize a stopped
vehicle, pedestrians or an oncoming vehicle. Always look ahead
cautiously to prevent unexpected and sudden situations from occurring. |
| • |
The smart cruise control system is not a substitute for safe
driving practices but a supplementary function only. It is the
responsibility of the driver to always check the speed and the distance
to the vehicle ahead. |
| • |
In front of you, vehicles moving with a frequent lane change
may cause a delay in the system's reaction or may cause the system to
react to a vehicle actually in adjacent lane. Always look ahead
cautiously to prevent unexpected and sudden situations from occurring. |
| • |
Your vehicle may accelerate when a vehicle ahead of you
disappears. When you are warned that the vehicle ahead of you is not
detected, drive with caution. 
|
| • |
When vehicles are at a standstill and the vehicle in front of
you changes to the next lane, be careful when your vehicle starts to
move because it may not recognize the stopped vehicle in front of you. 
|
| • |
Always look out for pedestrians when your vehicle is maintaining a distance with the vehicle ahead. 
|
| • |
Always be cautious for vehicles with higher height or vehicles carrying loads that sticks out to the back of the vehicle.
