Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for thevehicle.
NOTE
See page 385 for the maximum trailer and tongue weights recommended by Volvo.
•Observe the legal requirements of the state/province in which the vehicles are
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
Trailer towing does not normally present any particular problems, but take into considera-tion: • Increase tire pressure to recommended full pressure. See the tire inflation tableon page 316.
• When your vehicle is new, avoid towingheavy trailers during the first 620 miles(1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine cool-ant temperature should be closely watched when driving in hot climates orhilly terrain. Use a lower gear and turn offthe air conditioner if the temperaturegauge needle enters the red range.
• If the automatic transmission begins tooverheat, a message will be displayed inthe text window.
• Avoid overload and other abusive opera-tion.
• Hauling a trailer affects handling, durabil-ity, and economy.
• It is necessary to balance trailer brakeswith the towing vehicle brakes to providea safe stop (check and observe state/local regulations).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch isnot being used.
WARNING
• Bumper-attached trailer hitches must not be used on Volvos, nor shouldsafety chains be attached to thebumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulicbrake system directly to the vehiclebrake system, nor a trailer's lightingsystem directly to the vehicle lightingsystem. Consult your nearest author-ized Volvo retailer for correct installa-tion.
• When towing a trailer, the trailer'ssafety wire must be correctly fastenedto the hole or hook provided in thetrailer hitch on the vehicle. The safetywire should never be fastened to orwound around the drawbar ball.

Towing a trailer

305
FunctionA vehicle towing a trailer may begin to sway for 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 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 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 89 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.

Having the vehicle towed by a tow truck
Call for professional help from an authorized towing company. Volvo recommends the useof 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.
CAUTION
•The vehicle should always be towed in the forward direction.
• Vehicles with All Wheel Drive (AWD)*that are being towed with the frontwheels off the ground should not betowed at a speed above approx.45 mph (70 km/h) and should not betowed farther than 30 miles (50 km).
Towing the vehicle
1. With the remote key fully pressed into the
ignition 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, seepage 125 to provide current for releas-ing the electric parking brake and tomove the gear selector from the
P
position to N. If this is not possible,
see page 130 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.

Winter driving conditions
Snow chainsSnow chains can be used on your Volvo with the following restrictions:• Snow chains should be installed on front wheels only. Use only Volvo approvedsnow chains.
• If accessory, aftermarket or "custom"tires and wheels are installed and are of asize different than the original tires andwheels, chains in some cases CANNOTbe used. Sufficient clearances betweenchains and brakes, suspension and bodycomponents must be maintained.
• Some strap-on type chains will interferewith brake components and thereforeCANNOT be used.
• All Wheel Drive models
: Snow chains
should only be installed on the frontwheels.
• Certain size tires may not allow theassembly of snow chains/traction devi-ces.
Consult your Volvo retailer for additional
snow chain information.
CAUTION
• Check local regulations regarding the use of snow chains before installing.
• Use single-sided snow chains only.
• Always follow the chain manufactur-er's installation instructions carefully.Install chains as tightly as possible andretighten periodically.
• Never exceed the chain manufactur-er's specified maximum speed limit.(Under no circumstances should youexceed 31 mph (50 km/h).
• Avoid bumps, holes or sharp turnswhen driving with snow chains.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns aswell as locked wheel braking.
Snow tires, studded tires 1
Tires for winter use:
•
Owners who live in or regularly commute through areas with sustained periods ofsnow or icy driving conditions arestrongly advised to fit suitable winter tires to help retain the highest degree of trac-tion.
• It is important to install winter tires on allfour wheels to help retain traction duringcornering, braking, and accelerating. Fail-ure to do so could reduce traction to anunsafe level or adversely affect handling.
• Do not mix tires of different design as thiscould also negatively affect overall tireroad grip.
• Winter tires wear more quickly on dryroads in warm weather. They should beremoved when the winter driving seasonhas ended.
• Studded tires should be run-in 300 – 600 miles (500 – 1000 km) during whichthe vehicle should be driven as smoothlyas possible to give the studs the opportu-nity to seat properly in the tires. The tiresshould have the same rotational directionthroughout their entire lifetime.
NOTE
Please consult state or provincial regula- tions restricting the use of studded wintertires before installing such tires.

The brake fluid should always be between the MIN
and MAX marks on the inside of the res-
ervoir. Check, without removing the cap, thatthere is sufficient fluid in the reservoir. Fluid type : DOT 4 boiling point >536 °F
(>280 °C).Replace : The fluid should be replaced
according to the intervals specified in the Warranty and Service Records Informationbooklet. When driving under extremely hard condi- tions (mountain driving, etc), it may be neces-sary to replace the fluid more often. Consult atrained and qualified Volvo service technician. Always entrust brake fluid changing to a trained and qualified Volvo service technician.
WARNING
• If the fluid level is below the
MIN mark
in the reservoir or if a brake-related message is shown in the informationdisplay: DO NOT DRIVE . Have the car
towed to a trained and qualified Volvoservice technician and have the brakesystem inspected.
• Dot 4 should never be mixed with anyother type of brake fluid.
Filling1. Turn and open the cover.
2. Unscrew the reservoir cap and fill the
fluid. The level must be between the MIN
and MAX marks.
Power steering fluid
Check the level frequently. The fluid does not require changing. The fluid level must bebetween the MIN and MAX marks. For
capacities and recommended fluid grade, seepage 389.
WARNING
If a problem should occur in the power steering system or if the vehicle has noelectrical current and must be towed, it isstill possible to steer the vehicle. However,keep in mind that greater effort will berequired to turn the steering wheel.
CAUTION
Keep the area around the power steering fluid reservoir clean when checking.

washers do not have facilities for washing the underbody.
NOTE
Condensation may form temporarily on the inside of the lenses of exterior lights suchas headlights, fog lights, or taillights. Thisis normal and the lights are designed towithstand moisture. Normally, condensa-tion will dissipate after the lights have beenon for a short time.
CAUTION
•
Before driving into an automatic car wash, turn off the optional rain sensorto avoid damaging the windshield wip-ers.
• Make sure that side view mirrors, aux-iliary lamps, etc, are secure, and thatany antenna(s) are retracted orremoved. Otherwise there is risk of themachine dislodging them.
• Chromed wheels:
Clean chrome-
plated wheels using the same deter-gents used for the body of the vehicle.Aggressive wheel-cleaning agents canpermanently stain chrome-platedwheels.
WARNING
• When the vehicle is driven immediately after being washed, apply the brakes,including the parking brake, severaltimes in order to remove any moisturefrom the brake linings.
• Engine cleaning agents should not beused when the engine is warm. Thisconstitutes a fire risk.
Polishing and waxing
•
Normally, polishing is not required during the first year after delivery, however, wax-ing may be beneficial.
• Before applying polish or wax the vehiclemust be washed and dried. Tar spots canbe removed with kerosene or tar remover.Difficult spots may require a fine rubbingcompound.
• After polishing use liquid or paste wax.
• Several commercially available productscontain both polish and wax.
• Waxing alone does not substitute for pol-ishing a dull surface.
• A wide range of polymer-based waxescan be purchased today. These waxesare easy to use and produce a long-last-ing, high-gloss finish that protects the bodywork against oxidation, road dirt andfading.
• Do not polish or wax your vehicle in directsunlight (the surface of the vehicle shouldnot be warmer than 113 °F (45 °C).
CAUTION
Volvo does not recommend the use of long-life or durable paint protection coat-ings, some of which may claim to preventpitting, fading, oxidation, etc. These coat-ings have not been tested by Volvo forcompatibility with your vehicle's clear coat.Some of them may cause the clear coat tosoften, crack, or cloud. Damage caused byapplication of paint protection coatingsmay not be covered under your vehicle'spaint warranty.
Cleaning the interior
Only use cleaning agents and car care prod- ucts recommended by Volvo. Clean regularlyand follow the instructions included with thecar care product.
Upholstery care
