Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to help stabilize a vehicle that is towing a trailerwhen the vehicle and trailer have begun tosway and is part of the stability system. Forinformation on the stability system, see Stabil-ity system – introduction (p. 175)
FunctionA vehicle towing a trailer may begin to swayfor various reasons. Normally this only occursat high speeds but, for example, if the traileris overloaded or if the load is unevenly dis-tributed in the trailer, there is risk of swayingat speeds between approximately 45-55 mph(70-90 km/h). Swaying may be caused by factors such as: •The vehicle and trailer are hit by a sud- den, strong crosswind
• The vehicle and trailer are traveling on anuneven road surface or drive over a bump
• Sudden movements of the steering wheel
Facts about TSA
• TSA intervenes at speeds above approxi-mately 40 mph (60 km/h)
• The stability system symbol in the instru-ment panel will flash when TSA is working
• If the driver switches off the stability sys-tem's Spin Control function, TSA will alsobe switched off (but will be on again thenext time the engine is started) •
TSA may not intervene when the vehicleand trailer begin to sway if the driver triesto compensate for the swaying motion bymoving the steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very diffi- cult to stop, which makes it difficult to controlthe vehicle and trailer. The TSA system continuously monitors the vehicle's movements, particularly lateralmovement. If the system detects a tendencyto sway, the brakes are applied individuallyon the front wheels, which has a stabilizingeffect on the vehicle and trailer. This is oftenenough to enable the driver to regain controlof the vehicle. If this is not adequate to stop the swaying motion, the brakes are applied to all of thewheels on the vehicle and on the trailer if it isequipped with brakes, and engine power istemporarily reduced. As the swaying motionbegins to decrease and the vehicle-trailerhave once again become stable, TSA will nowstop regulating the brakes/engine power andthe driver regains control of the vehicle.

Towing the vehicle
Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to reg-ulations regarding maximum towing speed,length and type of towing device, lighting, etc.
1. With the remote key fully pressed into theignition slot 22
, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the igni- tion slot 23
for the entire time that the vehi-
cle is being towed.
3. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This willhelp prevent jarring movements of thevehicle being towed.
4. Be prepared to apply the brakes to stop the vehicle being towed.CAUTION
General towing precautions:
• Please check with state and local authorities before attempting this typeof towing, as vehicles being towed aresubject to regulations regarding maxi-mum towing speed, length and type oftowing device, lighting, etc.
• If the vehicle's battery is dead, seeJump starting (p. 250) to provide cur-rent for releasing the electric parkingbrake and to move the gear selectorfrom the
P position to N. If this is not
possible, see Transmission – shiftlockoverride (p. 255) for information aboutmanually overriding the shiftlock sys-tem to move the gear selector from P
to N.
• Maximum speed: 50 mph (80 km/h).Do not exceed the maximum allowabletowing speed.
• Maximum distance with front wheelson ground: 50 miles (80 km).
• The vehicle should only be towed inthe forward direction.

Attaching the towing eyeletThe towing eyelet is located under the floor of the cargo area, with the spare tire.This eyelet must be screwed into thepositions provided on the right sides ofeither the front or rear bumper (see illus-tration).
There are two different types of covers over the openings for the towing eyeletand they have to be opened differently.
• If the cover has a notch, insert a coin, etc., into the notch and pry open theedge of the cover. Open the covercompletely and remove it.
• If the cover has a mark along one edgeor in a corner, press the mark whileprying out the opposite side/cornerusing a coin, etc. Open the cover andremove it.
Screw the towing eyelet in place, first by hand and then using the tire iron until it issecurely in place. After the vehicle has been towed, the eyelet should be removed and returned to its stor-age location. Press the cover for the attachment point back into position.
WARNING
• When the vehicle is being towed, the ignition should be in mode
II (in mode
I , all of the vehicle's airbags are deac-
tivated). For more information, seeIgnition modes (p. 79)
• Never remove the remote key from theignition slot when the vehicle is beingtowed. For vehicles with keyless drive,the remote key must remain inside thevehicle.
• The power brakes and power steeringwill not function when the engine is notrunning. Approximately 5 times morepressure will be required on the brakepedal and the steering wheel will beconsiderably harder to turn.
• The towing eyelets must not be usedfor pulling the vehicle out of a ditch orfor any similar purpose involvingsevere strain.

Towing by tow truck
When necessary, call for professional help from an authorized towing company. Volvorecommends the use of flat bed equipment.
CAUTION
In certain conditions, the towing eyelet may be used to pull the vehicle onto aflatbed tow truck.
• The vehicle's position and ground clearance determine if it can be pulledup onto a flatbed tow truck using thetowing eyelet.
• If the angle of the tow truck’s ramp istoo steep or the ground clearanceunder the vehicle is insufficient, dam-age could occur by attempting to pullthe vehicle using the towing eyelet.
• If necessary, lift the vehicle using thetow truck’s lifting device.
WARNING
No person or object should be behind the tow truck while the vehicle is being pulledup onto the flatbed.

Tires – general information
Your vehicle is equipped with tires according to the vehicle's tire information placard on theB-pillar (the structural member at the side ofthe vehicle, at the rear of the driver's dooropening).
Introduction
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheelcombination designed to provide maxi-mum dry pavement performance with con-sideration for hydroplaning resistance.They may be more susceptible to roadhazard damage and, depending on drivingconditions, may achieve a tread life of lessthan 20,000 miles (30,000 km). Even if thisvehicle is equipped with Volvo’s advancedAWD or stability system, these tires are notdesigned for winter driving, and should bereplaced with winter tires when weatherconditions dictate.
The tires have good road holding characteris- tics and offer good handling on dry and wetsurfaces. It should be noted however that thetires have been developed to give these fea-tures on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higherdegree of road holding on slippery surfacesthan tires without the "all-season" rating.However, for optimum road holding on icy orsnow-covered roads, we recommend suitablewinter tires on all four wheels. When replacing tires, be sure that the new tires are the same size designation, type(radial) and preferably from the same manu-facturer, on all four wheels. Otherwise there isa risk of altering the car's roadholding andhandling characteristics.
Tire rotationYour vehicle has no required tire rotation. Tirewear is affected by a number of factors suchas tire inflation, ambient temperature, drivingstyle, etc.
NOTE
•
If the tires are rotated, they should only be moved from front to rear orvice versa. They should never be rota-ted left to right/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000miles (5,000 km) and thereafter at6,000-mile (10,000-km) intervals.Some customers find that tire rotationmay help to get extra mileage from tirelife.
• Tire rotation should only be performedif front/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).

Tires – storage and age
When storing complete wheels (tires mounted on rims), they should be suspended off thefloor or placed on their sides on the floor.
New Tires
Remember that tires are perishable goods. Asof 2000, the manufacturing week and year(Department of Transportation (DOT) stamp)will be indicated with 4 digits (e.g., 1513means that the tire illustrated was manufac-tured during week 15 of 2013).
Tire ageTires degrade over time, even when they are not being used. It is recommended that tiresgenerally be replaced after 6 years of normalservice. Heat caused by hot climates, fre-quent high loading conditions or Ultra Violet(U.V.) exposure can accelerate the agingprocess. The temporary spare
1
should also
be replaced at 6-year intervals, even if it hasnever been used. A tire's age can be determined by the DOT stamp on the sidewall (see the illustration). A tire with e.g., visible cracks or discoloration should be replaced immediately.
Storing wheels and tiresWhen storing completes wheels (tires moun-ted on rims), they should be suspended offthe floor or placed on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but shouldnot be suspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never bestored in close proximity to solvents, gaso-line, oils, etc.
WARNING
• The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unap-proved wheel/tire size combinationscan negatively affect your vehicle'sstability and handling.
• Any damage caused by installation ofunapproved wheel/tire size combina-tions will not be covered by your newvehicle warranty. Volvo assumes noresponsibility for death, injury, orexpenses that may result from suchinstallations.

Tires – tread wear indicator
The tires have wear indicator strips running across or parallel to the tread.
G021829
The letters TWI are printed on the side of the
tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visibleand indicate that the tire should be replaced.Tires with less than 1/16" (1.6 mm) tread offervery poor traction. When replacing worn tires, it is recommended that the tire be identical in type (radial) andsize as the one being replaced. Using a tire ofthe same make (manufacturer) will preventalteration of the driving characteristics of thevehicle.

Tires – tire economy
A smooth driving style and correct inflation pressure can help prolong the tires' servicelife. • Maintain correct tire pressure. The tire inflation table, see Tire inflation – pressuretable (p. 300).
• Avoid fast starts, hard braking and tirescreeching.
• Tire wear increases with speed.
• Correct front wheel alignment is veryimportant.
• Unbalanced wheels impair tire economyand driving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with themost tread should be mounted on therear wheels to reduce the chance of over-steer during hard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.

Changing a wheel – direction of rotation
Incorrectly mounted tires impair the car's braking properties and ability to force asiderain, snow and slush.
Summer and winter tires
G021778
The arrows shows the direction of rotation of the tire
• The tires with the most tread should always be on the rear axle (to help reducethe risk of skidding).
• When switching between summer andwinter tires, mark the tires to indicatewhere they were mounted on the car,e.g., LF = left front, RR = right rear
• Tires with tread designed to roll in onlyone direction are marked with an arrowon the sidewall.
• Contact a Volvo workshop if you areunsure about the tread depth.
