City Safety limitations
City Safety functionality may be reduced in cer-tain situations.

Surroundings
Low objects
Hanging objects, such as flags for overhangingloads or accessories such as auxiliary lights orfront protective grids that extend beyond theheight of the hood, may limit City Safety function-ality.

Slippery road conditions
The extended braking distance on slippery roadsmay reduce City Safety's capacity to help avoid acollision. In these types of situations, the Anti-lock Braking System and Electronic Stability Con-
trol (ESC68) will help provide optimal brakingpower with maintained stability.

Backlighting
The visual warning signal in the windshield maybe difficult to detect in bright sunlight, if there arereflections, or if the driver is wearing sunglassesor not looking straight ahead.

Heat
If the temperature in the passenger compartmentis high due to e.g. bright sunlight, the visual warn-ing signal in the windshield may be temporarilydisabled.
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 and replacement of City Safetycomponents may only be performed by aworkshop – an authorized Volvo workshop isrecommended.
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.

Leveling control* and suspension
Self-leveling and suspension functions are con-trolled automatically.
Rear leveling control keeps the rear section ofthe vehicle at the same height regardless of load.Leveling control may also remain active when thevehicle is parked.

Shock absorbers (Four-C)
The shock absorbers are adapted to the selecteddrive mode and vehicle speed. The shock absorb-ers are normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface and the vehicle's acceleration,braking and cornering.
Transporting
When transporting the vehicle on a ferry, train ortruck, only secure (lash) the vehicle around thetires, not using any other parts of the chassis.Changes in the pneumatic suspension may occurduring transport, which could adversely affect thelashing and result in damage.

Preparing for a long trip
It is important to have the vehicle's systems andequipment checked carefully before driving longdistances.
Check that:
the engine is running properly and that fuelconsumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlightheight if the vehicle is carrying a heavy load
tire tread depth and air pressure are at cor-rect levels. Change to snow tires when driv-ing in areas where there is a risk of snowy oricy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Tread wear indicator
The tread wear indicator shows the status of thetire's tread.
The tread wear indicator is a narrow elevatedstrip running across the tire's longitudinal treadgrooves. The letters TWI (Tread Wear Indicator)are visible on the side of the tire. When approxi-mately 1.6 mm (1/16 inch) is left on the tread,the tread will be at the same height as the treadwear indicator. Replace the tire as soon as possi-ble. Tires with low tread offer very poor traction inrain or snow.

Tire terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional markings,notes or warnings such as standard load, radialtubeless, etc.
Tire information placard: A placard show-ing the OE (Original Equipment) tire sizes,recommended inflation pressure, and themaximum weight the vehicle can carry.
Tire Identification Number (TIN): A numberon the sidewall of each tire providing infor-mation about the tire brand and manufactur-ing plant, tire size and date of manufacture.
Inflation pressure: A measure of theamount of air in a tire.
Standard load: A class of P-metric or Metrictires designed to carry a maximum load at 35psi [37 psi (2.5 bar) for Metric tires]. Increas-ing the inflation pressure beyond this pres-sure will not increase the tires load carryingcapability.
Extra load: A class of P-metric or Metrictires designed to carry a heavier maximumload at 41 psi [43 psi (2.9 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetire's load carrying capability.
kPa: Kilopascal, a metric unit of air pressure.
PSI: Pounds per square inch, a standard unitof air pressure.
B-pillar: The structural member at the sideof the vehicle behind the front door.
Bead area of the tire: Area of the tire nextto the rim.
Sidewall of the tire: Area between the beadarea and the tread.
Tread area of the tire: Area of the perime-ter of the tire that contacts the road whenmounted on the vehicle.
Rim: The metal support (wheel) for a tire or atire and tube assembly upon which the tirebeads are seated.
Maximum load rating: a figure indicatingthe maximum load in pounds and kilogramsthat can be carried by the tire. This rating isestablished by the tire manufacturer.
Maximum permissible inflation pressure:the greatest amount of air pressure thatshould ever be put in the tire. This limit is setby the tire manufacturer.
Recommended tire inflation pressure:inflation pressure, established by Volvo,which is based on the type of tires that aremounted on a vehicle at the factory. Thisinformation can be found on the tire inflationplacard(s) located on the driver's side B-pillarand in the tire inflation table in this chapter.
Cold tires: The tires are considered to becold when they have the same temperatureas the surrounding (ambient) air. This tem-
