Common camera and radar limitations
Obstructed camera
The area marked in the illustration must be cleaned regularly and kept free of decals, objects, solar film,etc.
The camera is located on the upper interior section of the windshield along with the radarsensor. Do not place, affix or mount anything on the inside or outside of the windshield, or in frontof or around the camera and radar sensor –this could disrupt camera and radar-basedfunctions. It could cause functions to bereduced, deactivated completely or to producean incorrect function response.
High temperatures
If the temperature in the passenger compart- ment is very high, the camera/radar sensorwill switch off temporarily forapprox. 15 minutes after the engine is startedto protect its electronic components. Whenthe temperature has cooled sufficiently, thecamera/radar sensor will automatically restart.
Damaged windshield
NOTE
Failure to take action could result in reduced performance for the driver supportsystems that use the camera and radarunit. It could cause functions to bereduced, deactivated completely or to pro-duce an incorrect function response.
To avoid the risk of malfunction of the driver support systems that use the radar sensor, thefollowing also apply:
If there are cracks, scratches or stonechips on the windshield in front of any ofthe camera and radar sensor "windows"and this covers an area ofabout 0.5 × 3.0 mm (0.02 × 0.12 in.) ormore, contact a workshop to have the windshield replaced 126
.
Volvo advises
against repairing cracks,
scratches or stone chips in the area in front of the camera and radar sensor – the entire windshield should instead bereplaced.
Before replacing the windshield, contact a workshop 126
to verify that the right wind-
shield has been ordered and installed.
The same type of windshield wipers or wipers approved by Volvo should be usedfor replacement.
If the windshield is replaced, the cameraand radar sensor must be recalibrated by a workshop 126
to help ensure proper func-
tioning of all of the vehicle's camera and radar-based systems.
Additional radar limitations
Vehicle speed
The radar sensor's ability to detect a vehicle ahead is significantly reduced if the speed ofthe vehicle ahead differs greatly from yourvehicle's speed.
126 An authorized Volvo workshop is recommended.

Limited field of vision
The radar sensor has a limited field of vision. In some situations, it may detect a vehicle laterthan expected or not at all.
The radar sensor's field of vision
The radar sensor's detection of vehicles very close to your vehicle may be delayedin certain situations, e.g. if a vehicle pulls in between your vehicle and the vehicledirectly ahead.
Small vehicles, such as motorcycles, or vehicles that are not driving in the centerof the lane may remain undetected.
In curves, the radar may detect the a dif- ferent vehicle than intended or lose sightof a target vehicle.
Low trailers
Low trailer in the radar shadow
Low trailers may also be difficult or even impossible for the radar to detect. The drivershould be extra alert when driving behind vehi- cles towing low trailers when Adaptive Cruise Control
* or Pilot Assist
* is activated.
Additional camera limitations
Reduced visibility
Cameras have the same limitations as the human eye. In other words, their “vision" isimpaired by adverse weather conditions suchas heavy snowfall/rain, dense fog, swirling dust/snow, etc. These conditions may reducethe function of systems that depend on thecamera or cause these systems to temporarilystop functioning. Strong sunlight, reflections from the road sur- face, ice or snow covering the road, a dirtyroad surface, or unclear lane marker lines maydrastically reduce the camera

limitations
Blind sectors
There are "blind" sectors between the cameras' fields of vision.
With the Park Assist Camera's 360° view *
selected, objects/obstacles may not be detected if they are located in the "joints"where the edges of the individual cameraviews meet.
WARNING
Even if it seems as though only a fairly small section of the screen image isobstructed, this may mean that a relativelylarge sector is hidden and obstacles theremay not be detected until they are verynear the vehicle.
Lighting conditions
The camera image is automatically adjusted according to the current lighting conditions.This means that the brightness and quality ofthe image may vary slightly. Poor lighting con-ditions may result in reduced image quality.
NOTE
A bike carrier and other accessories moun- ted on the rear of the vehicle can obscurethe camera's view.

Recommended camera and radar sensor maintenance
In order for the camera and radar units to function properly, they must be kept free ofdirt, ice, snow, etc. and should be washedregularly with water and car washing deter-gent.
NOTE
Dirt, ice and snow covering the sensors could cause false warnings, reduced func-tion, or no function.

Location of rear radar sensors. Keep the marked area clean (on both the left and right sides of the vehicle).
For best possible performance, it is impor- tant to keep the areas in front of the sen-sors clean.
Do not attach any objects, tape or decalsto the surface of the sensors.
Clean the camera lenses regularly usinglukewarm water and car washing deter-gent. Wash gently to avoid scratching thelens.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.

Camera and radar unit symbols and messages Here are examples of some of the messages and symbols related to the camera and radarunits that may be displayed in the instrumentpanel.Sensor blockedIf this symbol and the messageWindscreen sensor Sensor
blocked, see Owner's manual is
displayed in the instrument panel, it
means that the camera and radar unit are unable to detect other vehicles, cyclists,pedestrians and large animals in front of thevehicle and that the vehicle's camera andradar-based functions may be obstructed.
The following table shows some of the situa- tions that can cause the message to be dis-played, and suggested actions:
Cause Action
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow. Clean the windshield in front of the camera/radar sensor and remove dirt, iceand snow.
Thick fog, heavy rain or snow is blocking the radar signals or thecamera's range of visibility. No action. Heavy precipitation may sometimes prevent the camera/radar sensorfrom functioning.
Water or snow is spraying/swirling up and blocking the radarsignals or the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the cam-era/radar sensor from functioning.
There is dirt between the inside of the windshield and the cam-era/radar sensor. Consult a workshop to have the area of the windshield on the inside of the cam-era's casing cleaned. An authorized Volvo workshop is recommended.
Bright sunlight. No action. The camera/radar sensor will reset automatically when lighting con-ditions improve.

Fuel
Volvo recommends the use of detergent gas- oline to control engine deposits.
Deposit control gasoline (gasoline with detergent additives)
Detergent gasoline is effective in keeping injectors and intake valves clean. Consistentuse of deposit control gasolines will helpensure good driveability and fuel economy. Ifyou are not sure whether the gasoline containsdeposit control additives, check with the serv-ice station operator.
NOTE
Volvo recommends not using external fuel injector cleaning systems, e.g. do not adddetergent additives to gasoline before orafter refueling.
Unleaded fuelAll Volvo vehicles have a three-way catalytic converter and must only use unleaded gaso-line. US and Canadian regulations require thatpumps delivering unleaded gasoline arelabeled "UNLEADED". Only the nozzles ofthese pumps will fit in your vehicle's fuel fillerinlet. It is unlawful to dispense leaded fuel intoa vehicle labeled "unleaded gasoline only".Leaded gasoline damages the three-way cata-lytic converter and the heated oxygen sensor system. Repeated use of leaded gasoline willlessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicleinspection programs will make detection ofmisfueling easier, possibly resulting in emis-sion test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tricar-bonyl (MMT). If such fuels are used, yourEmission Control System performancemay be affected, and the Check EngineLight (malfunction indicator light) locatedon your instrument panel may light. If thisoccurs, please return your vehicle to atrained and qualified Volvo service techni-cian for service.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local lawsrequire that the service pump be marked indi-cating use of alcohols or ethers. However,there are areas in which the pumps areunmarked. If you are not sure whether there isalcohol or ethers in the gasoline you buy,check with the service station operator. To

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle if youdetect engine misfire, noticeable loss ofpower or other unusual operating condi-tions, such as engine overheating or back-firing. A properly tuned engine will helpavoid malfunctions that could damage thethree-way catalytic converter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, whichcan come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cata-lytic converter or exhaust system over-heating.
Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.
