When Driving
i-ACTIVSENSE
NOTE
Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions correctly and each system may not operate normally.
The rear surface of a vehicle ahead does not re À ect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
Vehicles ahead with low vehicle height and thus less area for re À ecting radio waves.
Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tyres and onto your windscreen.
The luggage compartment is loaded with heavy objects or the rear passenger seats
are occupied.
Ice, snow, or soiling is on the front surface of the front emblem.
During inclement weather such as rain, snow, or sand storms.
When driving near facilities or objects emitting strong radio waves.
Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions.
The beginning and end of a curve.
Roads with continuous curves.
Narrow lane roads due to road construction or lane closures.
The vehicle ahead enters the radar sensor's blind spot.
The vehicle ahead is running abnormally due to accident or vehicle damage.
Roads with repeated up and down slopes
Driving on poor roads or unpaved roads.
The distance between your vehicle and the vehicle ahead is extremely short.
A vehicle suddenly comes close such as by cutting into the lane.
To prevent incorrect operation of the system, use tyres of the same speci ¿ ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use
tyres with signi ¿ cantly different wear patterns or tyre pressures on the same vehicle
(Including the temporary spare tyre).
If the battery power is weak, the system may not operate correctly.
If the vehicle is driven on a road with little traf ¿ c and few vehicles ahead or
obstructions for the radar sensor (front) to detect, the sensor detects that the radar
sensor (front) is dirty and the Smart Brake Support/Smart City Brake Support (SBS/
SCBS) Warning Light (amber) may be temporarily turned on. However, it does not
indicate a malfunction.
