improves cold-weather starting as well as decreasing fuel consumption while theengine is warming up. Full synthetic0W-30 oil is recommended for driving inareas with sustained low temperatures.
• The load placed on the battery is greaterduring the winter since the windshieldwipers, lighting, etc., are used moreoften. Moreover, the capacity of the bat-tery decreases as the temperature drops.In very cold weather, a poorly chargedbattery can freeze and be damaged. It istherefore advisable to check the state ofcharge more frequently and spray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tireson all four wheels for winter driving, seepage 314.
• To prevent the washer fluid reservoir fromfreezing, add washer solvents containingantifreeze. This is important since dirt isoften splashed on the windshield duringwinter driving, requiring the frequent useof the washers and wipers. Volvo WasherSolvent should be diluted as follows:Down to 14 °F (–10 °C): 1 part washersolvent and 4 parts water Down to 5 °F(–15 °C): 1 part washer solvent and3 parts water Down to 0 °F (–18 °C):1 part washer solvent and 2 parts waterDown to –18 °F (–28 °C): 1 part washersolvent and 1 part water. •
Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.

NOTE
•When parking the vehicle with a trailer on a hill, apply the parking brakebefore putting the gear selector in
P.
Always follow the trailer manufactur-er's recommendations for wheelchocking.
• When starting on a hill, put the gearselector in
D before releasing the park-
ing brake. See also page 135 for moredetailed information about starting offon a hill while towing a trailer.
• If you use the manual (Geartronic) shiftpositions while towing a trailer, makesure the gear you select does not puttoo much strain on the engine (usingtoo high a gear).
• The drawbar assembly/trailer hitchmay be rated for trailers heavier thanthe vehicle is designed to tow. Pleaseadhere to Volvo's recommended trailerweights.
• Avoid driving with a trailer on inclinesof more than 15%.
Trailer cableAn adapter is required if the vehicle's trailer hitch has a 13-pin connector and the trailerhas 7 pins. Use an adapter cable approved by Volvo. Make sure the cable does not dragon the ground.

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 Dynamic Stability andTraction Control system (DSTC). See page142 for information on DSTC.
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 DSTC symbol (
) in the instru-
ment panel will flash when TSA is working
• If the driver switches off the DSTC sys- tem's Spin Control function, TSA will also be 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 nostop regulating the brakes/engine power andthe driver regains control of the vehicle.

Towing eyelet
G017464
Location of the towing eyelet
Attaching the towing eyelet
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). See page 87 for more infor-mation about ignition modes.
• 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 the vehicle
1. With the remote key fully pressed into theignition slot 1
, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the igni- tion slot 2
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, attachjumper cables (see page 123) to pro-vide current for releasing the electricparking brake and to move the gearselector from the
P position to N. If
this is not possible, see page 128 forinformation about manually overridingthe shiftlock system to move the gearselector 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.
Having the vehicle towed by a tow truck
Call for professional help from an authorized towing company.Volvo recommends the useof flat bed equipment. The towing eyelet may be used to pull the vehicle onto a flatbed tow truck if:
• The angle of the tow truck’s ramp is not more than 12 degrees from a horizontalplane
• The vehicle’s wheels rotate freely and rollstraight ahead
WARNING
No person or object should be behind the tow truck while the vehicle is being pulledup onto the flatbed.

Introduction
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).
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 DSTC 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.
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 rotationYour vehicle has no required tire rotation. Tire wear 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).
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 aging

process. The temporary spare
1
should also
be replaced at 6-year intervals, even if it has never 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.
Tread wear indicator
G021829
The tires have wear indicator strips running across or parallel to the tread. The letters TWI
are printed on the side of the tire. Whenapproximately 1/16" (1.6 mm) is left on thetread, these strips become visible and indi-cate that the tire should be replaced. Tires with less than 1/16" (1.6 mm) tread offer verypoor 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.
Improving tire economy
•
Maintain correct tire pressure. See the tire inflation table on page 307.
• Drive smoothly: avoid fast starts, hardbraking and tire screeching.
• 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.
Summer and winter tires
G021778
The arrows shows the direction of rotation of the tire
• When switching between summer and winter 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.
• Incorrectly mounted tires impair the car'sbraking properties and ability to forceaside rain, snow and slush.

•The tires with the most tread should always be at the rear (to reduce the risk ofskidding).
• Contact a Volvo workshop if you areunsure about the tread depth.
Storing wheels and tiresWhen storing complete wheels (tires mounted on rims), they should be suspended off thefloor 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.
