Park Assist Camera *
Blind sectors
There are "blind" sectors between the cameras' fields ofvision.
With Park Assist Camera's 360° view* selected,objects/obstacles may not be detected if theyare located in the "joints" where the edges of theindividual camera views meet.
WARNING
Even if it seems as though only a fairly smallsection of the screen image is obstructed, thismay mean that a relatively large sector is hid-den and obstacles there may not be detecteduntil they are very near the vehicle.
Defective camera
If a camera sector is dark andcontains this symbol, this indi-cates that the camera is notfunctioning properly.
See the following illustration foran example.
The vehicle's left-side camera is malfunctioning.
A dark camera sector may also be displayed inthe following situations, but without the defectivecamera symbol:
a door is open
the trunk lid is open
a rearview mirror is folded in
Lighting conditions
The camera image is automatically adjustedaccording to the current lighting conditions. Thismeans that the brightness and quality of the
image may vary slightly. Poor lighting conditionsmay result in reduced image quality.
Rear Park Assist Camera
WARNING
Be extra cautious whenreversing if this symbol isshown when a trailer, bikecarrier or similar is attachedand electrically connectedto the vehicle.
The symbol indicates thatthe rear parking assist sensors are deacti-vated and will not warn of any obstacles.
NOTE
A bike carrier and other accessories mountedon the rear of the vehicle can obscure thecamera's view.

Recommended camera and radarsensor maintenance
In order for the camera and radar sensor to func-tion properly, they must be kept free of dirt, ice,snow, etc. and should be washed regularly withwater and car washing detergent.
NOTE
Dirt, ice and snow covering the sensors couldcause false warnings, reduced function, or nofunction.

Location of rear radar sensors. Keep the marked areaclean (on both the left and right sides of the vehicle).
For optimal performance, it is important tokeep the areas in front of the sensors clean.
Do not attach any objects, tape or decals tothe surface of the sensors.
Clean the camera lenses regularly usinglukewarm water and car washing detergent.Wash gently to avoid scratching the lens.

Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer-tain situations, it may be unable to detect pedes-trians, large animals, cyclists or vehicles, or it maydetect them later than expected.
Vehicles that are dirty may be detected later thanclean vehicles, and in dark conditions, motorcy-cles may be detected late or not at all.
If a text message displayed in the instrumentpanel indicates that the camera/radar sensor isobstructed, it may be difficult for City Safety todetect pedestrians, large animals, cyclists, vehi-cles or lane markings in front of the vehicle. CitySafety functionality may therefore be reduced.
Text messages may not be displayed for all situa-tions in which the windshield sensors areblocked. The driver must therefore always keepthe windshield in front of the camera/radar sen-sor clean.
CAUTION
Maintenance of driver support components
may only performed by a workshop50.
Driver intervention
Backing up
City Safety is temporarily deactivated when thevehicle is backing up.
Low speed
City Safety is not activated at very low speedsunder 4 km/h (3 mph). The system will thereforenot intervene in situations in which your vehicle isapproaching another vehicle very slowly, such aswhen parking.
Active driver
Action by the driver always has priority. CitySafety will therefore not react or will react at alater stage with a warning or intervention in situa-tions in which the driver is clearly steering andoperating the accelerator pedal, even if a collisionis unavoidable.
An active and aware driving style may thereforedelay collision warnings and intervention in orderto minimize unnecessary warnings.
Other limitations
WARNING
Warnings and brake interventions can betriggered late or not at all if the traffic sit-uation or external influences prevent thecamera and radar unit from properlydetecting pedestrians, cyclists, large ani-mals or vehicles ahead of the vehicle.
To be able to detect vehicles at night, itsfront and rear lights must work and illumi-nate clearly.
The camera and radar unit have a limitedrange for pedestrians and cyclists – thesystem can provide effective warningsand brake interventions if the relativespeed is lower than 50 km/h (30 mph).For stationary or slow-moving vehicles,warnings and brake interventions areeffective at vehicle speeds of up to70 km/h (43 mph). Speed reduction forlarge animals is less than 15 km/h(9 mph) and can be achieved at vehiclespeeds over 70 km/h (43 mph). At lowerspeeds, the warning and brake interven-tion for large animals is less effective.
Warnings for stationary or slow-movingvehicles and large animals can be disen-gaged due to darkness or poor visibility.

Charging cable residual currentdevice
The charging cable has a circuit breaker thathelps protect against current overloads and ther-mal overheating.
WARNING
Charging the hybrid battery may only be donefrom approved, grounded 120/240 V outlets(AC, alternating current). If the electrical cir-cuit or electrical socket's capacity is notknown, let a licensed electrician inspect theelectrical circuit's capacity. Using a chargelevel that exceeds the electrical circuit's orelectrical outlet's capacity may start a fire ordamage the electrical circuit.
WARNING
The charging cable's residual currentbreaker helps protect the vehicle's charg-ing system but cannot ensure that an cur-rent overload will never occur.
Never use visibly worn or damaged elec-trical sockets. Doing so could lead to firesor serious injury.
Never connect the charging cable to anextension cord.
Maintenance or replacement of the hybridbattery may only be performed by atrained and qualified Volvo service techni-cian.
If the charging cable's residual current device istriggered, the blue indicator light in the chargingmodule will not illuminate when the chargingcable is plugged into an electrical outlet (or thered warning light will glow steadily). Have the out-let checked by a licensed electrician or try usinganother wall outlet.

Brake Assist System
The brake enhancing system, (BAS3), helpsincrease braking force and can thereby reducebraking distance.
The system monitors the driver's braking habitsand increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.

Braking on wet roads
Prolonged driving in heavy rain without brakingmay cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. Itwill then be necessary to apply greater pressureto the brake pedal. You should therefore maintaina greater distance to the vehicle ahead.
Firmly apply the brakes after washing the vehicleor driving on wet roads. This helps warm up thebrake discs, enabling them to dry more quicklyand protecting them against corrosion. Considerthe current traffic situation when braking.

Brakes (p. 397)
Braking on salted roads (p. 399)
Braking on salted roads
When driving on salted roads, a layer of salt mayform on the brake discs and brake pads.
This could increase stopping distance. Maintainan extra large safety distance to the vehicleahead. Make sure to also:
Apply the brakes from time to time to helpremove salt. Make sure braking does notpose a risk to any other road users.
Gently apply the brakes when you have fin-ished driving and before driving again.

Maintenance of the brake system
Regularly check the brake system componentsfor wear.
To keep the vehicle as safe and reliable as possi-ble, follow the Volvo service schedule specified inthe Warranty and Maintenance Records Informa-tion booklet. New and replaced brake pads andbrake discs do not provide optimal braking effectuntil they are "broken in" by driving a few hun-dred kilometers (miles). Compensate for thereduced braking effect by applying greater pres-sure to the brake pedal. Volvo recommends onlyusing brake pads approved for your Volvo.
CAUTION
The brake system's components should beregularly checked for wear.
Contact a workshop for advice on how to dothis or let a workshop perform the inspection- an authorized Volvo workshop is recom-mended.
