WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle. Do not use Pilot Assist in demanding driving conditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps. In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog, slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations: • High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override PilotAssist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills. Thedriver should be attentive and prepared to applythe brakes in these situations. Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
Additional information
•
The Off Road drive mode cannot be
selected if Pilot Assist is activated.
• Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.

CAUTION
•Service and maintenance on City Safety may only be carried out by a trained andqualified Volvo service technician.
• If a crack, scratch or stone chip shouldoccur in the section of the windshield infront the camera/radar sensor, contact atrained and qualified Volvo service techni-cian to repair or replace the windshield.Failing to do so may result in reducedCity Safety functionality.
• This can also result in certain functionsbeing reduced or disabled, or they mayrespond incorrectly.
To help avoid the risk of incorrect, reduced ordisabled functionality for driver support sys-tems using the camera or radar sensors:
• Volvo recommends that cracks, scratchesor stone chips on the windshield in front of the camera/radar sensor should
not
be repaired; in such cases, the entire windshield should be replaced.
• Before the windshield is replaced, con-tact a Volvo retailer to ensure that thecorrect windshield is ordered and instal-led. If the wrong type of windshield isused, this may cause City Safety to func-tion improperly or not at all.
• Volvo recommends the use of only Genu-ine Volvo Replacement Windshields.
• When replacing windshield wipers, use the same type or ones approved by Volvo.
After the windshield has been replaced, thecamera/radar sensor will have to be recalibra-ted by a trained and qualified Volvo servicetechnician to help ensure proper function ofall of the vehicle's camera-/radar-based sys-tems.
MaintenanceIn order for camera and radar sensor to function properly, the area of the windshield must be keptfree of dirt, ice, snow, etc. and should be washedregularly with a suitable car washing detergent.
NOTE
Dirt, ice and/or snow covering the camera and radar sensors reduce functionality andmay disable the vehicle's camera-/radar-based systems. This can also result in certain functions being reduced or disabled, or they may respond incorrectly.

Camera limitations
The camera used by several of the driver support systems has certain limitations, which also affectthe systems using it.
Reduced visibility
WARNING
• The camera has the same limitations as the human eye. In other words, its “visionis impaired” by adverse weather condi-tions such as heavy snowfall, dense fog,etc. These conditions may reduce thefunction of systems that depend on thecamera or cause these systems to tem-porarily stop functioning.
• Strong sunlight, reflections from the roadsurface, ice or snow covering the road, adirty road surface, or unclear lane markerlines may drastically reduce the camera

CauseAction
Water or snow on the surface of the road swirl up and block radar signals or the camera's view. No action. The driver should be extra alert in conditions of this type.
There is dirt between the inside of the windshield and the camera/radar sensor. Have the area of the windshield cleaned by a trained and qualified Volvo service technician.
Strong backlighting No action required. The came will reset automatically when lightingconditions improve.
High temperaturesIf the temperature in the passenger compartment is very high, the camera and radar sensor may betemporarily turned off for approx. 15 minutesafter the engine has been started to protect theirelectronic components. When the temperaturehas cooled sufficiently, the camera and radarsensor will restart automatically.

Blind Spot Information (BLIS) *
limitations
Blind Spot Information functionality may be reduced in certain situations.
• Dirt, ice and snow on the sensors may reduce functionality and prevent the systemfrom providing warnings.
• Do not attach any objects, tape, decals, etc.,on the surface of the sensors.
• BLIS is deactivated if a trailer is attached tothe vehicle's electrical system.
Maintenance
The BLIS/CTA 5
sensors are located on the
inside of the rear fenders/bumper.
Keep the highlighted area clean (on both sides of the vehicle) - generic illustration
For the system to function optimally, the area over and around the sensors must be kept clean.
CAUTION
Repairs to the BLIS/CTA systems and/or repainting the rear bumper should only bedone by a trained and qualified Volvo servicetechnician.

Cross Traffic Alert (CTA) *
Cross Traffic Alert (CTA) is a supplementary part of Blind Spot Information and is intended todetect vehicles crossing behind your vehiclewhile you are backing up.
When does Cross Traffic Alert function
Principle for CTA
CTA supplements BLIS by warning the driver of crossing traffic behind your vehicle, for example,when backing out of a parking space. It is primarily designed to detect another vehicle but in certain cases may also detect pedestriansor smaller objects such as bicycles. CTA is only activated when the vehicle is rolling rearward or when the gear selector is put inreverse.

limitations
The Park Assist Camera system has certain limi- tations that the driver should be aware of.
NOTE
Bicycle carriers or other accessories mounted on the trunk lid may obstruct the camera'sfield of vision.
Blind sectorsEven if a fairly small section of the screen image appears to be obstructed, this may mean that arelatively large area is hidden and objects theremay not be detected until they are very near thevehicle.
The "blind" sectors between the cameras' fields of vision
With 360° view selected, objects/obstacles may
not be detected at the edges of the individual cameras' fields of vision.
Defective cameraIf a camera sector is dark andcontains this symbol, this indi-cates that the camera is notfunctioning properly (see thefollowing illustration).
In this example, the driver's side camera is not function- ing
