NOTE
In the following cases, the Forward Sensing Camera (FSC) may not be able to detect
target objects correctly.
Under bad weather condition, such as rain, fog and snow.
The window washer is being used or the windscreen wipers are not used when it's
raining.
Ice, fog, snow, frost, rainfall, dirt, or foreign matter such as a plastic bag is stuck on
the windscreen.
Trucks with low loading platforms and vehicles with an extremely low or high
pro ¿ le.
When driving next to walls with no patterning (including fences and longitudinally
striped walls).
The tail lights of the vehicle ahead are turned off.
A vehicle is outside the illumination range of the headlights.
The vehicle is making a sharp turn, or ascending or descending a steep slope.
Entering or exiting a tunnel.
Heavy luggage is loaded causing the vehicle to tilt.
Strong light is shone at the front of the vehicle (back light or high-beam light from
on-coming vehicles).
There are many light emitters on the vehicle ahead.
When the vehicle ahead is not equipped with tail lights or the tail lights are turned
off at nighttime.
Elongated luggage or cargo is loaded onto installed roof rails and covers the Forward
Sensing Camera (FSC).
Exhaust gas from the vehicle in front, sand, snow, and water vapour rising from
manholes and grating, and water splashed into the air.
When towing a malfunctioning vehicle.
The vehicle is driven with tyres having signi ¿ cantly different wear.
The vehicle is driven on down slopes or bumpy roads.
There are water puddles on the road.
The surroundings are dark such as during the night, early evening, or early morning,
or in a tunnel or indoor parking lot.
The illumination brightness of the headlights is reduced or the headlight illumination
is weakened due to dirt or a deviated optical axis.
The target object enters the blind spot of the Forward Sensing Camera (FSC).
A person or object bursts onto the road from the shoulder or cuts right in front of
you.
You change lanes and approach a vehicle ahead.
When driving extremely close to the target object.
Tyre chains or a temporary spare tyre is installed.
The vehicle ahead has a special shape. For example, a vehicle towing a trailer house
or a boat, or a vehicle carrier carrying a vehicle with its front pointed rearward.

When Driving

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 boot/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.
