Pilot Assist *
Pilot Assist helps the driver to drive the car between the lane's side markings using steeringassistance as well as to maintain an even speed,combined with a preselected time interval to thevehicle ahead.
The Pilot Assist function gives more comfortable driving and a more relaxed driving experienceduring, for example, long journeys on motorwaysin even traffic flows.
The camera and radar unit measures the distance to the vehicle ahead and detects side markings 9
.
Camera and radar unit
Distance readers
Readers, side markings The driver selects the desired speed and a time interval to the vehicle ahead. Pilot Assist scansthe distance to the vehicle ahead and the lane'sside markings on the road surface using thecamera and radar unit. The preset time interval ismaintained with automatic speed adjustmentwhilst the steering assistance helps to positionthe car in the lane. Pilot Assist steering assistance takes into account the speed of the preceding car and thelane markings. The driver can at any time ignorethe Pilot Assist steering recommendation andsteer in another direction, e.g. to change lane oravoid an obstruction on the road. If Pilot Assist cannot interpret the lane unambig- uously, e.g. if the camera and radar unit does notsee the lane's side markings, Pilot Assist tempo-rarily deactivates steering assistance, butresumes it if the lane can be interpreted again -although the speed and distance control func-tions remain active.
NOTE
Pilot Assist steering assistance is deactivated and is resumed without prior warning.
The current status of steering assistance is indicated by thecolour of the steering wheel'ssymbol: • GREEN steering wheel indi- cates active steering assis-
tance • GREY steering wheel (as in illustration) indi- cates deactivated steering assistance.

WARNING
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 andintervene if Pilot Assist does not provide suit-able steering assistance or maintain a suita-ble speed or suitable time interval. Read all the sections about this function in the owner's manual in order to learn about itslimitations, of which the driver should beaware before the function is used. Pilot Assist must only be used if there are clear lane lines painted on the road surfaceon each side of the lane. All other useinvolves increased risk of contact with sur-rounding obstacles that are not detected bythe function. The driver always bears responsibility for how the car is controlled as well as for maintainingthe correct distance and speed, even whenPilot Assist is being used.
Pilot Assist regulates the speed with acceleration and braking. It is normal for the brakes to emit alow sound when they are being used to adjustthe speed. Pilot Assist attempts to regulate the speed smoothly. In situations that demand sudden brak-ing the driver must brake himself/herself. Thisapplies in case of large speed differences or ifthe vehicle in front brakes suddenly. Due to the limitations of the camera and radar unit, brakingmay come unexpectedly or not at all. Pilot Assist aims to follow the vehicle ahead in the same lane at a time interval set by the driver.If the radar unit cannot see any vehicle in frontthen the car will instead maintain the speed setand stored by the driver. This also takes place ifthe speed of the vehicle ahead increases andexceeds the stored speed. The following applies for cars with automatic gearbox:
• Pilot Assist can follow another vehicle atspeeds from 0 km/h up to 200 km/h(125 mph).
• Pilot Assist can give steering assistance fromalmost stationary up to 140 km/h (87 mph).
The following applies for cars with manual gear-box: • Pilot Assist can follow another vehicle at speeds from 30 km/h (20 mph) up to200 km/h (125 mph).
• Pilot Assist can give steering assistance from30 km/h (20 mph) up to 140 km/h(87 mph).
WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver must intervene if the systemdoes not detect a vehicle in front. Pilot Assist does not brake for people, ani- mals, objects, small vehicles (e.g. cycles andmotorcycles), low trailers as well as oncoming,slow or stationary vehicles. Do not use Pilot Assist, for example, in city traffic, at junctions, on slippery surfaces, witha lot of water or slush on the road, in heavyrain/snow, in poor visibility, on winding roads,on slip roads, or with a trailer connected tothe car.
IMPORTANT
Maintenance of Pilot Assist components must only be performed at a workshop - an author-ised Volvo workshop is recommended.

Activating and starting the Pilot Assist
*
Pilot Assist must first be activated and then started to be able to control speed and distanceand to give steering assistance.
NOTE: The illustration is schematic - details may vary depending on car model.
In order to start the Pilot Assist it is required that:
• The driver's seatbelt must be buckled and the driver's door must be closed.
• There must be a vehicle (the "target vehicle")within reasonable distance in front of the car,or the current speed must be at least15 km/h (9 mph).
• For cars with manual gearbox. Speed mustbe at the lowest 30 km/h (20 mph).

Press
▶ (6).
> The
symbol changes to Pilot Assist
in standby mode (8).
2. Press the steering wheel button
(2).
> Pilot Assist is started and current speed is stored, which is shown with figures in the centre of the speedometer.
...or... With the adaptive cruise control started:
–Press ▶ (6).
> Pilot Assist is started.
Pilot Assist steering assistance is only active when the steeringwheel symbol (2) has changedfrom GREY to GREEN. Pilot Assist only regulates the time interval to the vehicle
ahead when the distance symbol shows a vehicle(1) above the steering wheel symbol.
At the same time a speed range is marked. The higher speed is the stored/selected speed and thelower speed is that of the vehi-cle ahead (target vehicle).
Hands on the steering wheelIn order for Pilot Assist to function, the driver must have his/her hands on the steering wheel.The system continually monitors this. If hands arenot detected on the steering wheel then a textmessage is shown, prompting the driver toactively steer the car. If this is not done, anacoustic warning signal will also be given. If that does not prompt the driver to put his/her hands on the steering wheel either, Pilot Assistchanges to standby mode. Following which, PilotAssist must be restarted with the steering wheel button
.
NOTE
Note that Pilot Assist only works when the driver has hands on the steering wheel.

Setting the time interval for Pilot Assist *
Pilot Assist can be set with different time inter- vals.
Different time intervals to the vehicle in front can be selectedand shown in the driver displayas 1-5 horizontal lines - themore lines the longer the timeinterval. One line representsabout 1 second to the vehicle
in front, 5 lines represents about 3 seconds.
NOTE
When the symbol in the driver display shows a car and a steering wheel, Pilot Assist fol-lows a vehicle in front at a preset time gap. When only one steering wheel is shown, there is no vehicle within a reasonable distanceahead.
Control for time interval.
Decrease time interval
Increase time interval
Distance indicator
–Press the steering wheel button (1) or (2) to increase or decrease the time interval.
> The distance indicator (3) shows the cur- rent time interval.
In order to follow the vehicle ahead in a smooth and comfortable way, Pilot Assist allows the timeinterval to vary noticeably in certain conditions.For example, at low speed, when the distancesbecome short, Pilot Assist increases the timeinterval slightly. Note that a short time interval only allows the driver a short time to react and take action if anyunforeseen problem should arise.
NOTE
Only use the time intervals permitted by local traffic regulations. If Pilot Assist does not appear to react when activated, this may be because the time dis-tance to the vehicle in front is preventing anincrease in speed. The higher the speed the longer the calcula- ted distance in metres for a given time inter-val.
