Renault Koleos Owners Manual: System A

Operating principle

Using the radar sensor, the system calculates the distance separating the vehicle from the one in front and alerts the driver if there is a risk of a front-end collision.

The driver can then brake the vehicle to limit the damage arising from a collision.

Note: make sure that the radar sensor 1 is not obscured (by dirt, mud, snow etc. or by the fitting of accessories such as bullbars).

System A

Operation

While driving (at speeds of between 20 and 85 mph (30 and 140 km/h) ), if there is a risk of collision with the vehicle in front, the warning light 4 will be displayed on the instrument panel in red, alongside a beep.

If the driver depresses the brake pedal and the system still detects a risk of collision, the brake force is increased. If the driver fails to react following an alert of an imminent collision, the system activates the brakes.

System A

Activating or deactivating the system

For vehicles fitted with a navigation system On the multifunction screen 5, select the "Vehicle" menu, "Driving assistance", and "Active braking", and then choose "ON" or "OFF".

You can access menu "Driving assistance" directly from button 6 .

function activated

function deactivated

The warning light is displayed on the instrument panel when the system is deactivated. This system is reactivated each time the ignition is switched on.

Conditions for non-activation of the system

The system cannot be activated:

  • when the gear lever is in neutral;

  • when the parking brake is activated;

  • while cornering.

  • For 4-wheel drive vehicles, when Electronic Stability Programme (ESC) with understeer and traction control are deactivated (please see "Electronic Stability Programme (ESC) with understeer and traction control" above). Warning light comes on.

Operating faults

When the system detects an operating fault, the warning light lights up on the instrument panel, with the message "Active braking disconnected".

There are two possibilities:

  • the system is temporarily disrupted (for example: radar obscured by dirt, mud, snow etc.). In this case, park the vehicle and switch off the engine. Clean the detection zone of the radar. When you next start the engine, the warning light and the message go out
  • if this is not the case, this may arise from another cause; contact an Approved Dealer.

Consult an approved dealer.

The system A only detects vehicles driving in the same direction of traffic.

The system cannot detect motorcycles because of the difficulty in forecasting their trajectory.

 

Active emergency braking

This function is an additional driving aid. This function is not under any circumstances intended to replace the due care and attention of the driver, who should at all times be in control of the vehicle. The triggering of this function may be delayed or prevented when the system detects clear signs of control of the vehicle by the driver (action on the steering wheel, pedals etc.).

System servicing/repairs

  • In the event of an impact, the radar-camera or radar alignment may be changed, and its operation may consequently be affected.

    Deactivate the function, then consult an authorised dealer.

  • Any work in the area where the radar-camera or radar are located (repairs, replacements, windscreen modifications etc.) must be carried out by a qualified professional.
  • Fitting accessories which may block the radar is prohibited (bull bars etc.).

Only an authorised dealer is qualified to service the system.

In the event of system disturbance

Some conditions can disturb or damage the operation of the system, such as:

  • a complex environment (metal bridge, tunnel etc.);
  • poor weather conditions (snow, hail, black ice etc.);

Risk of inadvertent braking.

 

Limitation of the system operation
  • The system will only respond to vehicles which are moving or which have been sensed as moving.
  • The radar area should be kept clean and free of any modifications in order to ensure the proper operation of the system.
  • The system cannot respond to small vehicles such as motorbikes, bicycles or pedestrians as effectively as to other vehicles.
  • The system may not operate properly when the road surface is slippery (rain, snow, black ice etc.).

Deactivating the function

You must disable the function if:

  • the brake lights are not functioning;
  • the front of the vehicle has undergone an impact or been damaged;
  • the vehicle is being towed (breakdowns);

Halting the function

You can halt the active braking function at any time by tapping the accelerator pedal or by turning the steering wheel in a avoidance manoeuvre.

In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.
