163
CAUTION
Vehicles with AWD (All Wheel Drive) with the front wheels off the ground should notbe towed at speeds above 50 mph(70 km/h) or for distances longer than30 miles (50 km).
CAUTION
•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, do notattempt to start the vehicle by pushingor pulling it as this will damage thethree-way catalytic converter(s). Theengine must be jump started using anauxiliary battery (see page 152).
• If the vehicle is being towed on a flatbed truck, the towing eyelets must notbe used to pull the vehicle up onto theflat bed or to secure the vehicle on theflat bed. Consult the tow truck opera-tor.
WARNING
•The power brakes and power steering will 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.
G030862
Towing vehicles with front wheel drive/All Wheel Drive
Volvo recommends the use of flat bed equip- ment. If wheel lift equipment must be used, please use extreme caution to help avoid damage tothe vehicle.
In this case, the vehicle should
be towed with the rear wheels on theground if at all possible. If it is absolutely necessary to tow the vehicle with the front wheels on the ground, pleaserefer to the towing information on the previ-ous page.
CAUTION
• Sling-type equipment applied at the front will damage radiator and air con-ditioning lines.
• It is equally important not to use sling-type equipment at the rear or apply lift-ing equipment inside the rear wheels;serious damage to the rear axle mayresult.
• If the vehicle is being towed on a flatbed truck, the towing eyelets must notbe used to secure the vehicle on theflat bed. Consult the tow truck opera-tor.

Points to keep in mind when towing a trailer
•When towing trailers
without brakes, the
maximum permissible trailer weight is 1,700 lbs (750 kg).
• If necessary, redistribute the weight ofany cargo in the trailer to avoid excessiveweight on the trailer hitch.
• The maximum trailer weight listed in thetable for All Wheel Drive models,5,000 lbs (2250 kg) is only applicablewhen there are not more than two occu-pants in the vehicle, in the front seats,with a combined weight of 300 lbs(135 kg), with no other cargo in the vehi-cle.
• The maximum weight listed for FrontWheel Drive models, 4,000 lbs (1800 kg)is only applicable when there are notmore than four occupants in the vehicle,in the front seats and second row ofseats, with a combined weight of 600 lbs(270 kg), with no other cargo in the vehi-cle.
• Vehicles used for towing a trailer on aregular basis, or for long-distance high-way towing should be equipped with anautomatic transmission oil cooler andVolvo's automatic self-leveling system forthe rear suspension. Consult your Volvoretailer. •
Volvo recommends the use of Volvotrailer hitches that are specially designedfor the vehicle.
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
• Increase tire pressure to recommendedfull inflation pressure. See chapter"Wheels and tires."
• When your vehicle is new, avoid towingheavy trailers during the first 620 miles(1,000 km).
• Engine and transmission are subject toincreased loads. Therefore, engine cool-ant temperature should be closelywatched 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.
• 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.
• Remove the ball and drawbar assemblywhen the hitch is not being used.
• Volvo recommends the use of syntheticengine oil when towing a trailer over longdistances or in mountainous areas.
NOTE
•When parking the vehicle with a trailer on a hill, apply the parking brakebefore putting the gear selector in
P.
When starting on a hill, put the gearselector in D before releasing the park-
ing brake. Always follow the trailermanufacturer's recommendations forwheel chocking.
• 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).

Cold weather precautions
06
169
If you wish to check your vehicle before the approach of cold weather, the followingadvice is worth noting:
• Make sure that the engine coolant con- tains 50 percent antifreeze. Any othermixture will reduce freeze protection. Thisgives protection against freezing down to–31 °F (–35 °C). See section "Coolant".
• The use of "recycled" antifreeze is notapproved by Volvo. Different types ofantifreeze must not be mixed.
• Volvo recommends using only genuineVolvo antifreeze in your vehicle's radiator.Your Volvo retailer stocks plenty of Volvoengine coolant to protect your vehicleduring cold weather.
• Try to keep the
fuel tank well filled – this
prevents the formation of condensation inthe tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
• The viscosity of the engine oil is impor-tant. Oil with low viscosity (thinner oil)improves cold-weather starting as well asdecreasing 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 greater
during the winter since the windshieldwipers, lighting, etc. are used more often. Moreover, the capacity of the batterydecreases as the temperature drops. Invery cold weather, a poorly charged bat-tery 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 tires
on all four wheels for winter driving – seesection "Wheels and tires."
• To prevent the
washer fluid reservoir
from freezing, add washer solvents con-taining antifreeze (see page 224 for thelocation of the washer fluid reservoir).This is important since dirt is oftensplashed on the windshield during winterdriving, requiring the frequent use of thewashers and wipers. Volvo Washer Sol-vent should be diluted as follows:
• Down to 14 ° F (–10 ° C):
1 part washer
solvent and 4 parts water
• Down to 5 ° F (–15 ° C):
1 part washer
solvent and 3 parts water
• Down to 0 ° F (–18 ° C):
1 part washer
solvent and 2 parts water
• Down to –18 ° F (–28 ° C):
1 part washer
solvent and 1 part water
• Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid the use of de-icing sprays as they can cause damage to the locks.
W – Winter/Wet driving mode – enhanced vehicle traction
•Mode W will only function if the gear selector is in the (
D)rive position.
• Press the button at the base of the gearselector to engage/disengage this drivingmode.
• An LED in the button will light up to indi-cate that W is engaged and this will alsobe displayed in the instrument panel (seepage 58).
• This mode may be selected for starting/moving off on slippery roads.

06 Starting and driving
Before a long distance trip

170
It is always worthwhile to have your vehicle checked by a trained and qualified Volvoservice technician before driving long dis-tances. Your retailer or service technician willalso be able to supply you with bulbs, fuses,spark plugs and wiper blades for your use inthe event that problems occur. As a minimum, the following items should be checked before any long trip:• Check that engine runs smoothly and that fuel consumption is normal.
• Check for fuel, oil, and fluid leakage.
• Check transmission oil level 1
.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that are worn.Check tire pressures.
• The brakes, front wheel alignment, andsteering gear should be checked by atrained and qualified Volvo service techni-cian only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces. •
Have a word with your Volvo retailer ifyou intend to drive in countries where itmay be difficult to obtain the correct fuel.
• Consider your destination. If you will bedriving through an area where snow or iceare likely to occur, consider snow tires.

system’s compressor. If necessary, release air from the tire by turning the airrelease knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If you interrupt your trip for more than 1 hour, check the inflation pressure in thedamaged tire again before continuing.
Replacing the sealing compound container
The sealing compound container must be replaced if:• the tire sealing system has been used to repair a tire
• the container’s expiration date haspassed (see the date on decal).
NOTE
• After use, the sealing compound bot- tle, the hose, and certain other systemcomponents must be replaced. Pleaseconsult your Volvo retailer for replace-ment parts.
• If the sealing compound bottle’s expi-ration date has passed, please take itto a Volvo retailer or a recycling stationthat can properly dispose of harmfulsubstances.
Inflating tires
The tire sealing system can be used to inflate the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position 0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s inflation valve and screw the hose con- nector onto the valve as tightly as possi-ble by hand.
5. Connect the electrical wire to the nearest 12-volt socket in the vehicle. 6. Start the vehicle’s engine.
WARNING
•
The vehicle’s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be surethe vehicle is parked in a well ventilatedplace, or outdoors, before using thesystem. The parking brake should besecurely applied and the gear selectorshould be in the
P (park) position.
• Children should never be left unatten-ded in the vehicle when the engine isrunning.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to get a clear reading from the pressuregauge.
8. Refer to the tire inflation tables for the correct inflation pressure. If the tire needsto be inflated, start the tire sealing sys-tem’s compressor (press the on/offswitch to position I). If necessary, releaseair from the tire by turning the air releaseknob counterclockwise.

properly. Always check the TPMS malfunc- tion telltale after replacing one or more tiresor wheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the TPMS to continue to function prop-erly.
NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation pressure table inthis chapter or consult your Volvo retailer.
Erasing warning messagesWhen a low tire pressure warning message has been displayed, and the tire pressurewarning light has come on:
1. Use a tire pressure gauge to check theinflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pres- sure (consult the tire pressure placard or the table see page 183).
3. Drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster.
> This will erase the warning text and thewarning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
Changing wheels with TPMSPlease note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
• Only the factory-mounted wheels are equipped with TPMS sensors in thevalves.
• If the vehicle is equipped with a tempo-rary spare tire, this tire does not have aTPMS sensor.
• If wheels without TPMS sensors are mounted on the vehicle,
TIRE PRESS
SYST. SERVICE REQUIRED will be dis-
played each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes ormore.
• Once TPMS sensors are properly instal-led, the warning message should notreappear.
• Volvo recommends that TPMS sensorsbe fitted on all wheels used on the vehi-cle. Volvo does not recommend movingsensors back and forth between sets ofwheels.
NOTE
If a tire is changed or if the TPMS sensor is moved to another wheel, the sensor’svalve and valve core should be replaced.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straightonto the valve to help avoid bending orotherwise damaging the valve.
Recalibrating TPMS (Canadian models only)
In certain cases, it may be necessary to reca- librate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the infla-tion pressure table on page 183), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and turn the ignition key to position I or II
(see page 145 for additional information).
3. Turn the thumb wheel on the left-side steering wheel lever until

Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as optional equipment. The vehicle must beequipped with the Tire Pressure MonitoringSystem (TPMS) if tires of this type are instal-led. Tires of this type have specially reinforced sidewalls that make it possible to continuedriving to a limited extent even though the tirehas lost some or all of its inflation pressure.These tires are mounted on special rims (nor-mal tires can also be mounted on these rims). If an SST tire loses inflation pressure, the yel- low TPMS symbol illuminates in the instru-ment panel and a text message is also dis-played. If this happens, reduce speed to not more than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible. Drive carefully; it may be difficult to determine which tire is damaged. To find the damagedtire, check the inflation pressure in all fourtires.
WARNING
•
SST tires should only be mounted by service technicians who are familiarwith tires of this type.
• SST tires may only be mounted onvehicles equipped with TPMS.
• Do not drive faster than 50 mph(80 km/h) if TPMS indicates that a tirehas lost inflation pressure.
• Do not drive farther than 50 miles(80 km) before replacing a damagedSST tire.
• Drive carefully and avoid e.g., hardbraking or fast turns.
• SST tires must be replaced if they aredamaged. A tire of this type cannot berepaired.
