Setting a maximum height for the
power tailgate*
The tailgate can be set to stop opening at a cer-tain height, for example if the tailgate needs tobe opened in a garage with a low ceiling.
Setting maximum opening height:
1.Open the tailgate to the desired openingheight.
NOTE
It is not possible to program an opening posi-tion lower than half-open tailgate.
2.Press the button on the lower edge ofthe tailgate and hold for at least 3 seconds.
>Two brief audio signals will sound to indi-cate that the position has been stored.
Resetting to maximum opening position:
–Move the tailgate manually to its highest
possible position and press the buttonon the tailgate for at least 3 seconds.
>Two audio signals will sound to indicatethat the stored position has been erased.The tailgate can then be opened to itsmaximum position.
NOTE
If the system has been working continu-ously for a prolonged period of time, it willbe switched off to avoid overload. It canbe used again after approximately2 minutes.

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 (ESC72) 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
The vehicle's leveling control system adjusts thesuspension and shock absorbers automaticallyto help provide good comfort and control whiledriving. Leveling can also be controlled manuallyto facilitate loading or getting in and out of thevehicle.
Pneumatic suspension and shock
absorbers
The system is adapted to the selected drivemode and vehicle speed. The pneumatic suspen-sion reduces the vehicle's ground clearance athigher speeds to reduce air resistance andincrease stability. The shock absorbers are nor-mally set to provide the best possible comfortand are adjusted continuously according to theroad surface and the vehicle's acceleration, brak-ing and cornering.
The instrument panel indicateswhen the suspension level isbeing adjusted.
The following apply if a door or the tailgate isopened:
If a door is opened, the level can only beadjusted upwards.
If the tailgate is open, the level can only beadjusted downwards.
Parking
When parking, make sure that there is adequatespace above and below the vehicle since groundclearance may vary depending on e.g. ambient
temperature, how the vehicle is loaded, if loadingmode is used, which drive mode is selected afterthe engine is started, etc.
The level may also be adjusted a period after thevehicle is parked. This is to compensate for anyheight changes that may occur due to tempera-ture changes in the air springs when the vehiclecools.
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.

Low Speed Control
The low-speed function, Low Speed Control(LSC), facilitates and improves control and trac-tion on rough roads and slippery surfaces, e.g.when towing a trailer on grass or up boat ramps.
The function is included in the Off Road drivemode.
Low Speed Control is designed for driving onrough roads and when towing trailers at lowspeeds, up to approximately 40 km/h (25 mph).
When driving at low speeds, LSC prioritizes lowgears and all-wheel drive to help avoid wheel spinand improve traction on all wheels. The accelera-tor pedal will be less responsive to improve trac-tion and speed control at low speeds.
The function is activated together with HillDescent Control (HDC), which makes it possibleto control speed going down steep hills using theaccelerator pedal and reduces the need to usethe brake pedal. The system makes it possible tomaintain a low and uniform speed when drivingdown steep hills.

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

Winter driving
It is important to check the vehicle before drivingin cold/snowy conditions to make sure it can bedriven safely.
Before the cold season arrives:
Make sure the engine coolant contains 50%antifreeze. This mixture helps protect theengine from frost erosion down toapprox. -35 °C (-31 °F). Do not mix differenttypes of antifreeze as this could pose ahealth risk.
Keep the fuel tank well filled to prevent con-densation from forming.
Check the viscosity of the engine oil. Oil withlow viscosity (thinner oil) improves cold-weather starting and reduces fuel consump-tion when driving with a cold engine.
CAUTION
Low-viscosity oil should not be used with harddriving or in hot weather.
Check the condition and charge level of thestart battery. Cold weather places greaterdemands on the start battery and reduces itscapacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in the washerfluid reservoir.

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-

Tire sidewall designations
The following information can be found on atire's sidewall.
Federal law mandates that tire manufacturersplace standardized information on the sidewall ofall tires (see the illustration).
The vehicle has been certified with certain combi-nations of wheels and tires.
The following information is listed on the tiresidewall:
The tire designation:
NOTE
Please be aware that the following tire desig-nation is an example only and that this par-ticular tire may not be available on your vehi-cle.
1.215: the width of the tire (in millimeters)from sidewall edge to sidewall edge. Thelarger the number, the wider the tire.
2.65: The ratio of the tire's height to its widthin percent.
3.R: Radial tire (the designation RF and the
symbol indicate that the vehicle isequipped with optional self-supporting run
flat tires3.
4.15: The diameter of the wheel rim (ininches).
5.95: The tire's load index. In this example, aload index of 95 equals a maximum load of1521 lbs (690 kg).
6.H: The tire's speed rating, or the maximumspeed at which the tire is designed to bedriven for extended periods of time, carryinga permissible load for the vehicle, and withcorrect inflation pressure. For example, Hindicates a speed rating of 210 km/h(130 mph).
