Pilot Assist*

Pilot Assist helps the driver to drive the car between the road lane whilst at the same time maintaining a preselected time interval to the preceding vehicle.

Pilot Assist provides more comfortable driving in slow traffic - up to 50 km/h (30 mph) - on motorways and main roads.

The driver sets the desired time interval to the preceding vehicle. Pilot Assist scans the preceding vehicle and the lane markings with the camera and radar unit. The preset time interval is maintained with automatic speed adjustment whilst the steering assistance helps to position the car in the lane.

Pilot Assist steering assistance takes into account the speed of the preceding car and the lane markings. The driver can at any time ignore the Pilot Assist steering recommendation and steer in another direction, e.g. to change lane or avoid an obstruction on the road.

If the camera and radar unit does not sense the lane markings or a preceding vehicle, Pilot Assist is set in the standby mode.

When Pilot Assist is in the standby mode and the car comes too close to a preceding vehicle, the driver is instead warned by the Distance warning for the short distance (refer to Distance warning at the end of this section).


Pilot Assist is an aid which cannot handle all traffic, weather and road conditions.

The driver must always be observant with regard to the prevailing traffic conditions and intervene when Pilot Assist is not maintaining a suitable speed or suitable distance.

Read all the sections about this function in the owner's manual in order to learn about its limitations, of which the driver should be aware before the function is used.

Pilot Assist must only be used if there are clear lane lines painted on the road surface on each side of the lane. All other use involves increased risk of contact with surrounding obstacles that are not detected by the function.

The driver always bears responsibility for how the car is controlled as well as for maintaining the correct distance and speed, even when Pilot Assist is being used.

Pilot Assist attempts to regulate the speed smoothly. In situations that demand sudden braking the driver must brake himself/herself. This applies in case of large speed differences or if the vehicle in front brakes suddenly. Due to the limitations of the camera and radar unit, braking may come unexpectedly or not at all.

The stored speed for the Pilot Assist function is preset to 50 km/h (30 mph) and cannot be adjusted - if the speed of the vehicle in front increases to more than 50 km/h (30 mph) and is no longer within a reasonable distance, Pilot Assist is set to standby mode.


Maintenance of Pilot Assist components must only be performed at a workshop - an authorised Volvo workshop is recommended.

Pilot Assist regulates the speed with acceleration and braking. It is normal for the brakes to emit a low sound when Pilot Assist uses them.


Pilot Assist is not a collision avoidance system. The driver must intervene if the system does not detect a vehicle in front.

Pilot Assist does not brake for humans or animals, and not for small vehicles such as bicycles and motorcycles. Nor for low trailers, oncoming, slow or stationary vehicles and objects.

Do not use Pilot Assist, for example, in city traffic, in dense traffic, at junctions, on slippery surfaces, with a lot of water or slush on the road, in heavy rain/snow, in poor visibility, on winding roads or on slip roads.

Collision risk warning

P5-1546-Pilot Assist Princip m Koll-varning
Warning light.

Pilot Assist uses about 40% of the foot brake's capacity. If the car needs to be braked more heavily than Pilot Assist is capable of and the driver does not brake, the warning lamp and acoustic warning from City Safety are activated to alert the driver that immediate intervention is required.


The warning lamp may be difficult to see in strong sunlight or when wearing sunglasses.


P5-1507 HUD collision warning
A flashing symbol attracts the driver's attention.

If the car is fitted with a head-up display* the warning is displayed on the windscreen with a flashing symbol.


Pilot Assist only gives warning about vehicles whose camera and radar unit has been detected - therefore a warning may not occur or be delayed. Do not wait for a warning without braking when so required.
