Driving with a trailer
There are a number of things to consider whentowing 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 beapproved 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.

STARTING AND DRIVING
* Option/accessory.480
Follow applicable regulations regarding per-mitted speed and weight.
Drive slowly when towing a trailer up a longand steep incline.
The maximum trailer weights given only applyto altitudes up to 1000 meters (3280 feet)above sea level. At higher altitudes, enginepower (and thus the vehicle's climbing ability)is decreased due to the reduced air density,and the maximum trailer weight must there-fore be reduced. The weight of the vehicleand trailer must be decreased by 10% foreach additional 1000 m (3280 feet) or partthereof.
Avoid driving with a trailer on inclines of morethan 12%.
Avoid overloading and other incorrect use.
The trailer's brakes must be balanced withthe vehicle's brakes to help ensure safestops (follow applicable local regulations).
NOTE
To facilitate towing a trailer in a vehicle equip-ped with pneumatic suspension*, select: the
Suspension ControlDynamic setting inIndividual drive mode.
CAUTION
Bumper-attached trailer hitches must notbe used on Volvos, nor should safetychains be attached to the bumper.
Trailer hitches attaching to the vehiclerear axle must not be used.
Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
NOTE
The optional detachable trailer hitch may notbe available in all markets or on all models.Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer,driving at high altitudes and fuel quality arefactors that significantly increase a vehicle'sfuel consumption.
Trailer weights
WARNING
Please adhere to the recommendations provi-ded for trailer weight. If the recommendationsare not followed, the vehicle and trailer maybe difficult to control during evasive maneu-vers and braking.
NOTE
The specified maximum trailer weights arethose permitted by Volvo. National vehicleregulations may set additional restrictions ontrailer weight and speed. The trailer hitchesmay be certified for higher towing weightsthan the vehicle is permitted to tow.
Self-leveling suspension *
The vehicle's self-leveling system attempts tokeep the vehicle at a constant level, regardless ofload (up to the maximum permitted weight).When the vehicle is stationary, the rear end of thevehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weather
In certain conditions, there is a risk of overheat-ing when driving with a trailer. If overheating ofthe engine and drive system is detected, a warn-ing symbol will illuminate in the instrument panelalong with a message.

Trailer Stability Assist*
Trailer Stability Assist (TSA8) is a functiondesigned to help stabilize a vehicle that is tow-ing a trailer when the vehicle and trailer havebegun to sway. The function is part of the Elec-
tronic Stability Control system ESC9.
Reasons for swaying
A vehicle towing a trailer may begin to sway forvarious reasons. Normally this only occurs at highspeeds. However, if the trailer is overloaded orunevenly distributed, e.g. too far back, there is arisk of swaying even at low speeds.
Swaying may be caused by factors such as:
The vehicle and trailer are hit by a sudden,strong crosswind.
The vehicle and trailer are traveling on anuneven road or over a bump.
Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult orimpossible to stop it. This makes the vehicle andtrailer difficult to control and there is a risk ofswerving into oncoming traffic or driving off theroad.
Trailer Stability Assist function
Trailer Stability Assist continuously monitors thevehicle's movements, particularly lateral move-
ments. If swaying is detected, the brakes areapplied individually on the front wheels, which hasa stabilizing effect on the vehicle and trailer. Thisis often enough to enable the driver to regaincontrol of the vehicle.
If the Trailer Stability Assist function's firstattempt is not adequate to stop the swayingmotion, the brakes are applied on all wheels andengine power is temporarily reduced. As theswaying motion begins to decrease and the vehi-cle and trailer have once again become stable,TSA stops regulating the brakes/engine powerand the driver regains control of the vehicle.
NOTE
Trailer Stability Assist is deactivated if thedriver selects the sport mode by deactivatingESC in the center display's menu system.
Trailer Stability Assist may not intervene if thedriver tries to compensate for the swaying motionby moving the steering wheel rapidly, becausethe system will then not be able to determine if itis the trailer or the driver causing the swaying.

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-

Determining the vehicle's permittedweight
Properly loading your vehicle will provide maxi-mum return of vehicle design performance.
Weight designations
Before loading your vehicle, familiarize yourselfwith the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank offuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, includingcargo and optional equipment. When towing, tow-bar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be car-ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weightof occupants and cargo should never exceedXXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driverand passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driverand passengers from XXX kg or XXX lbs.
4. The resulting figure equals the availableamount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is 650lbs. (1400 - 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggageand cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4.
6. If your vehicle will be towing a trailer, loadfrom your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.

WARNING
Exceeding the permissible axle weight,gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.
