BLIS - operation

Updated 06/08/2023

BLIS (Blind Spot Information System) is a function designed for providing support for the driver when driving in dense traffic on roads with several lanes in the same direction.

Activate/deactivate BLIS

BLIS is activated when the engine is started. This is confirmed by the indicator lamps in the door panels flashing once.

P4-1220-BLIS På-/Av-knapp — Button for activating/deactivating.

The BLIS function can be deactivated/activated by pressing the BLIS button on the centre console.

Some combinations of the selected equipment leave no vacant space for a button in the centre console - in which case the function is handled by the car's menu system MY CAR1:

Select On or Off at Settings → Car settings → BLIS.

When BLIS is deactivated/activated the lamp in the button goes out/illuminates and the combined instrument panel confirms the change with a text message. The door panel indicator lamps flash once upon activation.

To extinguish the message:

Press the left stalk switch OK button.

Wait approx. 5 seconds – the message extinguishes.

When BLIS operates

P4-1220- BLIS Princip — Principle for BLIS: 1. Zone in blind spot. 2. Zone for quickly approaching vehicle.

The BLIS function is active at speeds above 10 km/h (6 mph).

The system is designed to react when:

the vehicle is overtaken by other vehicles
another vehicle is quickly approaching the vehicle.

When BLIS detects a vehicle in zone 1 or a quickly approaching vehicle in zone 2, the door panel BLIS lamp illuminates with a constant glow. If the driver activates the direction indicator on the same side as the warning in this situation then the BLIS lamp will change from a constant glow to flashing with a more intense light.

Warning

BLIS does not work in sharp bends.

BLIS does not work when the car is being reversed.

Limitations

Dirt, ice and snow covering sensors can reduce functionality and make it impossible to provide warnings. BLIS cannot detect hazards if it is covered.
Do not affix any objects, tape or labels in the area of the sensors.
BLIS is deactivated when a trailer is connected to the car's electrical system.

Important

Repair of the BLIS and CTA functions' components or repainting the bumpers must only be performed by a workshop - an authorised Volvo workshop is recommended.
