Pilot Assist
Pilot Assist helps the driver keep the vehicle in the current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
How Pilot Assist worksThe Pilot Assist function is primarily intended for use on highways and other major roads where itcan help provide a more comfortable and relaxingdriving experience.
The camera/radar sensor monitors the distance to the vehicle ahead and detects lane markings 61
.
Camera and radar sensor
Distance monitor
Lane marker line monitors The driver sets the desired speed and distance to the vehicle ahead. Pilot Assist monitors the dis-tance to the vehicle ahead and the traffic lane'sside markers using the camera and radar sensor.The system maintains the set time interval to thevehicle ahead by automatically adjusting yourvehicle's speed and keeps your vehicle in its laneby providing steering assistance. Pilot Assist's steering assistance is based on monitoring the direction of the vehicle ahead andthe traffic lane's side marker lines. The driver canoverride Pilot Assist's steering recommendationsat any time and steer in another direction, e.g. tochange lanes or avoid obstacles on the road. If the camera/radar sensor cannot detect the lane's side marker lines or if Pilot Assist is unablefor some other reason to clearly interpret thelane, Pilot Assist will temporarily deactivate steer-ing assistance until it can once again interpretthe lane markings. However, the speed and dis-tance warnings will remain active.
WARNING
Pilot Assist is deactivated automatically and resumes working without prior notice.
The color of the steering wheel symbol indicates the currentstatus of steering assistance: • GREEN indicates that steer- ing assistance is active • GRAY (as shown in illustra-
tion) indicates that steering assistance is deacti- vated.

WARNING
•The Pilot Assist function is supplementary driver support intended to facilitate driv-ing and help make it safer – it cannothandle all situations in all traffic, weatherand road conditions.
• The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
• Pilot Assist should only be used if thereare clear lane lines painted on each sideof the lane. All other use will increase therisk of contact with nearby obstacles thatcannot be detected by the functions.
• Pilot Assist is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theproper position within the lane, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
NOTE
Depending on market, this function may be either Standard or Optional.
Pilot Assist regulates speed by accelerating and braking. It is normal for the brakes to emit a slightsound when they are being used to adjust speed. Pilot Assist attempts to smoothly regulate speed. The driver must apply the brakes in situationsrequiring immediate braking. For example, whenthere are great differences in speed betweenvehicles or if the vehicle ahead brakes suddenly.Due to limitations in the camera and radar sen-sor, braking may occur unexpectedly or not at all. Pilot Assist is designed to follow a vehicle ahead in the same lane and maintain a time interval tothat vehicle set by the driver. If the radar sensordoes not detect a vehicle ahead, it will insteadmaintain the speed set by the driver. This will alsohappen if the speed of the vehicle aheadexceeds the set speed for your vehicle.
• Pilot Assist can follow another vehicle atspeeds from a standstill up to 200 km/h(125 mph).
• Pilot Assist can provide steering assistancefrom near-stationary speeds up to 140 km/h(87 mph).
WARNING
• Pilot Assist is not a collision avoidance system. The driver must intervene if thesystem fails to detect a vehicle ahead.
• Pilot Assist does not brake for people,animals, objects, small vehicles (e.g.cycles and motorcycles), low trailers aswell as oncoming, slow or stationary vehi-cles.
• Do not use Pilot Assist in demanding sit-uations, such as in city traffic, at intersec-tions, on slippery surfaces, with a lot ofwater or slush on the road, in heavy rain/snow, in poor visibility, on winding roads,on highway on- or off-ramps, or with atrailer connected to the vehicle.
CAUTION
Maintenance of the integrated components in Pilot Assist may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.
In curves and forks in the roadPilot Assist is designed to interact with the driver. The driver should never wait for steering assis-tance from Pilot Assist, but instead should alwaysbe ready to increase his or her own steeringefforts, particularly in curves.

When the vehicle is approaching an off-ramp or a fork in the road, the driver should steer towardthe desired lane to indicate to Pilot Assist thedesired direction of travel.
Pilot Assist strives to keep the vehicle
in the center of the lane
When Pilot Assist provides steering assistance, itstrives to position the vehicle in the center of thelane between the lane markings. For the smooth-est driving experience possible, the driver shouldpermit the vehicle to find the optimal positioning.The driver should check that the vehicle is posi-tioned safely in the lane and can always adjustthe vehicle's position by applying more force tothe steering wheel. If Pilot Assist does not position the vehicle appro- priately in the lane, the driver should turn off PilotAssist or switch to Adaptive Cruise Control.

Activating and starting Pilot Assist Pilot Assist must first be activated and then started before it can regulate speed and dis-tance and provide steering assistance.
Note: This illustration is general and details may vary depending on model.
To start Pilot Assist: •
The driver's seat belt must be buckled and the driver's door must be closed.
• There must be a vehicle ahead (target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least15 km/h (9 mph).

310With Adaptive Cruise Control in
standby mode:
1. Press the
▶ button on the steering wheel (6).
> The
symbol will change to Pilot
Assist in standby mode (8).
2. Press the
button on the steering wheel
(2).
> Pilot Assist will start and the current speed will be stored, which will be shown by numbers in the center of the speedom-eter.
...or... With Adaptive Cruise Control started:
–Press the ▶ button on the steering wheel (6).
> Pilot Assist will start.
Pilot Assist's steering assis- tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN. Pilot Assist will only regulate
the time interval to the vehicle ahead when the distance symbol shows a vehicle (1) over thesteering wheel symbol.
A speed interval will be marked at the same time. The higher speed is the set speed for your vehicle and thelower speed is the speed of thevehicle ahead (target vehicle).
Hands on the steering wheelPilot Assist only functions if the driver's hands are on the steering wheel. If Pilot Assist detectsthat the driver's hands are not on the steeringwheel, the driver will be instructed to activelysteer the vehicle by a text message and an audi-ble signal. If Pilot Assist still cannot detect the driver's hands on the steering wheel, the function will gointo standby mode. Pilot Assist must then be reactivated by pressing the
button on the
steering wheel.
NOTE
Note that the Pilot Assist function only works when the driver's hands are on the steeringwheel.
