Blind-Spot Collision Warning Settings
Setting
Blind-Spot Safety
With the engine on, select or deselect Driver Assistance Blind-Spot Safety’ from the Settings menu to set whether or not to use each function. If “Warning Only’ is selected, the function will warn the driver with a warning message and an audible warning depending on the collision risk levels. Braking will not be assisted. If ‘Off is selected, the function will turn off.
When the engine is restarted with the function off, the ‘Blind-Spot Safety System is Off message will appear on the cluster. If you change the setting from ‘Off to Warning Only, the warning light on the outside rearview mirror will blink for three seconds. In addition, if the engine is turned on when the function is set to Warning Only, the warning light on the outside rearview mirror will blink for three seconds.
WARNING
If Warning Only’ is selected, braking is not assisted. If ‘Off is selected, the driver should always be aware of the surroundings and drive safely.
Information
If the engine is restarted, the Blind-Spot Safety system will maintain the last setting.
Warning Timing
With the engine on, select Driver Assistance > Warning Timing’ from the Settings menu to change the initial warning activation time for the Blind-Spot Safety system.
When the vehicle is first delivered, Warning Timing is set to ‘Normal. If you change the Warning Timing, the warning time of other Driver Assistance systems may change.
Warning Volume
With the engine on, select ‘Driver Assistance> Warning Volume’ from the Settings menu to change the Warning Volume to ‘High’, ‘Medium’ or ‘Low’ for the Blind-Spot Safety system. If you change the Warning Volume, the warning volume of other Driver Assistance systems may change.

Select ‘Late’ for Warning Timing when traffic is light and when driving speed is slow.
Blind-Spot Collision Warning Operation
Blind-Spot Collision Warning 
Vehicle detection
To warn the driver a vehicle is detected, the warning light on the side view mirror will illuminate. Blind-Spot Collision Warning will operate when your vehicle speed is above 12 mph (20 km/h) and the speed of the vehicle in the blind spot area is above 7 mph (10 km/h).
Collision warning
A collision warning will operate when the turn signal is turned on in the direction of the detected vehicle. If the warning is only selected from the Settings menu, the collision warning will operate when your vehicle approaches the lane the blind spot vehicle is detected. To warn the driver of a collision, the warning light on the side view mirror will blink. At the same time, an audible warning will sound. When the turn signal is turned off or you move away from the lane, the collision warning will be canceled and Blind-Spot Collision Warning will return to the vehicle detection state.
WARNING
The detecting range of the rear corner radar is determined by the standard road width, therefore, on a narrow road, a Blind-Spot Collision Warning may detect other vehicles two lanes over and warn you. In contrast, on a wide road, Blind-Spot Collision Warning may not be able to detect a vehicle driving in the next lane and may not warn you. When the hazard warning light is on, the collision warning by the turn signal will not operate.
Information
If the driver’s seat is on the left side, the collision warning may occur when you turn left. Maintain a proper distance with the vehicles in the left lane. If the driver’s seat is on the right side, the collision warning may occur when you turn right. Maintain a proper distance with the vehicles in the right lane.
WARNING
Take the following precautions when using Blind-Spot Collision Warning:
- For your safety, only change the Settings after parking the vehicle at a safe location.
- If any other system’s warning message is displayed or an audible warning is generated, Blind-Spot Collision Warning’s warning message may not be displayed and audible warning may not be generated.
- You may not hear the warning sound of Blind-Spot Collision Warning if the surrounding is noisy.
- Blind-Spot Collision Warning may warn the driver late or may not warn the driver depending on the road and driving conditions.
- Driver should maintain control of the vehicle at all times. Do not depend on Blind-Spot Collision Warning. Maintain a safe braking distance, and if necessary, depress the brake pedal to reduce driving speed or to stop the vehicle.
