NOTE
Dirt, ice and snow covering the sensors reduce their function and can make measure-ment impossible.
Driver responsibilityThe driver should keep in mind that PAP is a parking aid ‒ not an infallible fully automatic sys-
tem. The driver must always be prepared to take control and cancel a parking sequence if neces-sary. There are a number of things to keep in mind when parking, including:
• The driver is always responsible for determin-ing if the space suggested by PAP is suita-ble for parking.
• Do not use PAP when using snow chains ora temporary spare tire.
• Do not use PAP if there are any objects pro-truding from the vehicle.
• Heavy rain or snowfall may inhibit PAP's abil-ity to accurately measure a parking space.
• While searching and measuring the parkingspace, PAP may be unable to detect objectslocated far into the space.
• PAP may not suggest parking spaces onnarrow streets if it does not detect sufficientspace for maneuvering the vehicle. •
Use approved tires 128
inflated to the correct
tire pressure because this affects PAP's abil-ity to provide parking assistance.
• PAP's function is based on the way the vehi-cles are parked behind and in front of yourparking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims couldbe damaged by the curb during the parkingprocedure.
• Perpendicular parking spaces may not bedetected or may be suggested unnecessarilyif a parked vehicle is sticking out more thanother parked vehicles.
• PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with sharp curves or bends. Alwaysmake sure that your vehicle is parallel to rel-evant parking spaces when PAP is measur-ing the parking space.
CAUTION
Switching to another approved wheel and/or tire dimension could change the tire circum-ference, which would then require the PAPsystem to be updated. Consult a workshop –an authorized Volvo workshop is recom-mended.

Installing the ball holder1. If necessary, remove the cotter pin from thelocking bolt and slide the locking bolt out of the towbar assembly.
2. Slide the ball holder into the towbar assem- bly.
3. Align the hole in the ball holder with the one in the towbar assembly.
4. Slide the locking bolt through the towbar assembly/ball holder.
5. Insert the cotter pin in the hole at the end of the locking bolt.
WARNING
• Be sure the towbar is securely locked in position before attaching anything to it.
• Always attach the trailer's safety wiresecurely to the towbar's safety wireattachment bracket.
Removing the ball holder1. Remove the cotter pin from the locking bolt
and slide the locking bolt out of the ballholder/towbar assembly.
2. Pull the ball holder out of the towbar assem- bly.

Driving with a trailer
There are a number of things to consider when towing a trailer, such as the towbar, the trailerand how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehi- cle's curb weight. The total weight of all passen-gers and any installed accessories, e.g. towbar,reduces the vehicle's load-carrying capacity bythe corresponding amount. • Towbars used on the vehicle must be approved for the applicable use.
• Distribute the load on the trailer so that theweight on the towbar complies with thespecified maximum towball weight. Thetongue weight is calculated as part of thevehicle's payload.
• Increase the tire pressure to the recom-mended pressure for a full load.
• The engine is subjected to more load thanusual when towing a trailer.
• Towing a trailer affects the vehicle's han-dling, durability and driving economy.
• Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
• On long and steep downgrades, the vehicle'sbrakes are subjected to much more loadthan usual. When manually shifting, down-shift and adapt speed accordingly.

Tire direction of rotation
Tires with tread designed to roll in only one direction are marked with an arrow on the side-wall.
The arrow shows the tire's direction of rotation.
• The tire should maintain the same direction of rotation throughout its service life.
• Tires should only be moved between thefront and back, never from right to left or viceversa.
• Incorrectly mounted tires impair the vehicle'sbraking properties and ability to force asiderain, snow and slush.
• The tires with the most tread should alwaysbe mounted on the rear wheels to helpreduce the risk of skidding.
NOTE
Use tires of the same type, dimensions and make (manufacturer) on each axle.

8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and
indicates that the tire meets all federalstandards. The next two numbers are thefactory code where the tire was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was made. For example,0717 means that the tire was manufacturedduring week 7 of 2017. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9. Tire Ply Composition and Material Used :
Indicates the number of plies indicates or thenumber of layers of rubber-coated fabric inthe tire tread and sidewall. Tire manufactur-ers also must indicate the ply materials in thetire and the sidewall, which include steel,nylon, polyester, and others.
10. Maximum Load : Indicates the maximum
load in pounds and kilograms that can becarried by the tire. Refer to the vehicle's tire information placard located on the B-Pillarfor the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperaturegrades .
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This limit is setby the tire manufacturer.
Speed SymbolA tire's Speed Symbol (SS) indicates the maxi-mum speed for which the tire has been certifiedand should be at least equivalent to the vehicle'stop speed. Winter tires, with or without studs, are exceptions and may use a lower SS. When winter tires areinstalled, the vehicle may not be driven fasterthan the tires' SS. The vehicle's speed should always be determined by the posted speed limit and traffic and roadconditions, not the tire's SS. The following table indicates the maximum per- missible speed for each SS.
M 130 km/h (81 mph)
Q 160 km/h (100 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph)

Adjusting tire pressureTire pressure decreases over time, which is nor- mal. The tire pressure must therefore beadjusted to maintain the recommended tire pres-sure.
Use the recommended inflation pressure for cold tires for optimal tire performance and wear.
NOTE
To help prevent incorrect inflation pressure, pressure should be checked when the tiresare cold. The tires are considered to be coldwhen they have reached the same tempera-ture as the ambient temperature (about 3hours after the vehicle was last driven). Afterdriving for a few kilometers, the tires will warmup and the pressure will increase.
1. Remove the valve cap from the tire and press the air pressure gauge firmly onto the valve.
2. Inflate to the recommended inflation pres- sure. 3. Screw the valve cap back on.
NOTE
•
After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tire to make sure there
are no nails or other embedded objects that could puncture the tire and cause air leak-age.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregulari-ties.
6. Repeat this procedure for each tire, including the spare tire 5
.
NOTE
If you have overfilled the tire, release air by pushing on the metal stem in the center ofthe valve. Then recheck the pressure withyour tire gauge. Some spare tires require higher inflation pres- sure than the other tires. Consult the tireinflation pressure table or the inflation pres-sure placard.

Recommended tire pressure
The tire pressure placard on the driver's side B pillar (between the front and the rear door) indi-cates tire pressure for different loads and speedconditions.
The placard specifies the designation for the fac- tory-mounted tires on the vehicle, as well as loadlimits and inflation pressures.

Tire pressure monitoring system
*
The tire pressure monitoring system, Tyre Pressure Monitoring System (TPMS), provides awarning symbol in the instrument panel if pres-sure is too low in one or more tires.
SymbolExplanation
This symbol illuminates to indicate low inflation pressure. If there is a system malfunction, the inflation pressure warning symbolwill flash for approximately oneminute and then glow steadily.
System descriptionThe tire pressure monitoring system measures differences in rotational speed between thewheels through the ABS system to determine ifthe tires are properly inflated. If inflation pressure in a tire is too low, its diameter (and consequently its rotational speed) changes. By comparing thetires with each other, the system can determine ifthe pressure in one or more tires is too low.
General information about the tire pressure
monitoring system
In the following description, the tire monitoring system is generally referred to as TPMS. Each tire, including the spare tire (if provided) 6
,
should be checked monthly when cold and infla- ted to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard ortire inflation pressure label. (If your vehicle hastires of a different size than the size indicated onthe vehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure telltale. When the system detects a mal-
