CTA (Cross Traffic Alert)*
CTA is activated when the engine is started. This is confirmed by the indicator lamps for BLIS in the door panels flashing once.
The CTA function can be deactivated with the Parking assistance On/Off button. The BLIS lamp flashes once on activation
CTA is a supplementary aid and does not work in all situations.
CTA is no substitute for a safe driving style and the use of rearview and door mirrors.
CTA can never replace the driver's responsibility and attention - it is always the driver's responsibility to reverse in a safe manner.
When CTA operates
CTA supplements the BLIS function by being able to see crossing traffic from the side during reversing, such as when reversing out of a parking space.
CTA is primarily designed to detect vehicles. In favourable conditions, it may also be able to detect smaller objects, such as cyclists and pedestrians.
CTA is only active during reversing and is activated automatically when the gearbox's reverse position is selected.
- If CTA detects something approaching from the side, an acoustic warning signal sounds. The signal comes from either the left or the right-hand speaker, depending on the direction from which the object is approaching.
- CTA also warns by illuminating the BLIS lamps.
- An additional warning is provided in the form of an illuminated icon in the display screen's PAS graphics.
CTA does not perform optimally in all situations, but has a certain limitation - for example, the CTA sensors cannot "see" through other parked vehicles or obstructing objects.
Here are some examples of when CTA's "field of vision" may be limited from the beginning and approaching vehicles cannot therefore be detected until they are very close:
However, when the driver is slowly reversing the car, the angle is changed in relation to the vehicle/object that is blocking, at which the blind sector rapidly decreases.
Examples of further limitations:
- Dirt, ice and snow covering sensors can reduce functionality and make it impossible to provide warnings. CTA cannot detect hazards if it is covered.
- Do not affix any objects, tape or labels in the area of the sensors.
- CTA is deactivated when a trailer is connected to the car’s electrical system.
The sensors for the CTA functions are located inside the rear wing/bumper on each side of the car.
- To ensure optimal functionality the areas in front of the sensors must be kept clean.
