Citroen C3: Driving / Blind Spot Monitoring

Refer to the General recommendations on the use of driving and manoeuvring aids.

This system includes sensors, placed on the sides of the bumpers, and warns the driver of the potentially dangerous presence of another vehicle (car, truck, motorcycle) in the blind spot areas of their vehicle (areas hidden from the driver's field of vision).

The warning is given by a fixed warning lamp that appears in the door mirror on the side in question:

• immediately, when being overtaken;
• after a delay of about one second, when overtaking a vehicle slowly.

Activation / Deactivation

It is set via the Driving / Vehicle touch screen menu.

When the function is activated, this warning lamp comes on in the instrument panel.

When starting the vehicle, the warning lamp comes on in each mirror to indicate that the system is activated.

The state of the system stays in the memory when switching off the ignition.

The system is automatically deactivated when towing with a towing device approved by CITROËN.

Conditions for operation

• All vehicles are moving in the same direction and in adjacent lanes.
• The speed of your vehicle must be between 7 and 87 mph (12 and 140 km/h).
• When overtaking a vehicle, the speed difference is less than 6 mph (10 km/h).
• When overtaken by a vehicle, the speed difference is less than 16 mph (25 km/h).
• Traffic is flowing normally.
• Overtaking a vehicle over a certain period of time and the vehicle being overtaken remains in the blind spot.
• You are driving on a straight or slightly curved road.
• Your vehicle is not pulling a trailer, a caravan, etc.

Operating limits

No alert is triggered in the following conditions:

• In the presence of non-moving objects (parked vehicles, barriers, street lamps, road signs, etc.).
• Oncoming traffic.
• Driving on a winding road or a sharp corner.
• When overtaking or being overtaken by a very long vehicle (lorry, bus, etc.) that is detected in the rear blind spot but is also present in the driver’s front field of vision.
• When overtaking quickly.
• In very heavy traffic: vehicles detected in front and behind are confused with a lorry or a stationary object.

Malfunction

In the event of a malfunction, this warning lamp flashes for a few moments in the instrument panel, accompanied by the Service warning lamp coming on and the display of a message.

Contact a CITROËN dealer or a qualified workshop to have the system checked.

The system may suffer temporary interference in certain weather conditions (rain, hail, etc.).

In particular, driving on a wet surface or moving from a dry area to a wet area can cause false alerts (for example, the presence of a fog of water droplets in the blind spot angle is interpreted as a vehicle).

In bad or wintry weather, ensure that the sensors are not covered by mud, ice or snow.

Take care not to cover the warning zone in the door mirrors or the detection zones on the front and rear bumpers with adhesive labels or other objects; they may hamper correct operation of the system.
