load. See the "Tire pressure" section. Loads should be distributed so that capacity weightor maximum permissible axle loads are notexceeded.
Driving through water
•
The vehicle can be driven through water up to a depth of approximately 10 in.(25 cm), at a maximum speed of 6 mph(10 km/h).
• Take particular care when driving throughflowing water.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.
WARNING
•Avoid driving through standing or rushing water. Doing so can be dan-gerous and it may also be difficult todetermine the actual depth of thewater.
• If water cannot be avoided, after driv-ing through the water, press lightly onthe brake pedal to ensure that thebrakes are functioning normally. Wateror mud can make the brake liningsslippery, resulting in delayed brakingeffect.
CAUTION
•Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than 10 in (25 cm), water mayenter the differential and the transmis-sion. This reduces the oil's lubricatingcapacity and may shorten the servicelife of these components.
• Do not allow the vehicle to stand inwater up to the door sills longer thanabsolutely necessary. This could resultin electrical malfunctions.
• If the engine has been stopped whilethe vehicle is in water, do not attemptto restart it. Have the vehicle towedout of the water.
Engine and cooling systemUnder special conditions, for example when driving in hilly terrain, extreme heat or withheavy loads, there is a risk that the engineand cooling system will overheat. Proceed asfollows to avoid overheating the engine. •
Maintain a low speed when driving with a trailer up long, steep hills.
• Do not turn the engine off immediatelywhen stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after theengine has been switched off.
• Remove any auxiliary lights from in front of the grille when driving in hot weatherconditions.
• Do not exceed engine speeds of4500 rpm if driving with a trailer in hillyterrain. The oil temperature could becometoo high.
Conserving electrical currentKeep the following in mind to help minimize battery drain:
• When the engine is not running, avoid using ignition mode
II. Many electrical
systems (the audio system, the optionalnavigation system, power windows, etc)will function in ignition modes 0 and I.
These modes reduce drain on the battery.
• Please keep in mind that using systems,accessories, etc., that consume a greatdeal of current when the engine is notrunning could result in the battery beingcompletely drained. Driving or having theengine running for approximately15 minutes will help keep the batterycharged.

Vehicles equipped with the high perform- ance 4-cylinder engines (B4204T9 and B4204T10) require premium fuel 2
.
TOP TIER Detergent GasolineVolvo endorses the use of “TOP TIER Deter- gent Gasoline” where available to help main-tain engine performance and reliability. TOPTIER Detergent Gasoline meets a new stand-ard jointly established by leading automotivemanufactures to meet the needs of today’sadvanced engines. Qualifying gasoline retail-ers (stations) will, in most cases, identify theirgasoline as having met the “TOP TIER Deter-gent Gasoline” standards.
NOTE
Information about TOP TIER Detergent Gasoline is available atwww.toptiergas.com.
Demanding drivingIn demanding driving conditions, such as operating the vehicle in hot weather, towing atrailer, or driving for extended periods athigher altitudes than normal, it may be advis-able to switch to higher octane fuel (91 orhigher) or to change gasoline brands to fullyutilize your engine's capacity, and for thesmoothest possible operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be nec-essary to fill the tank more than oncebefore a difference in engine operation isnoticeable.
Fuel FormulationsDo not use gasoline that contains lead as a knock inhibitor, and do not use lead addi-tives. Besides damaging the exhaust emis-sion control systems on your vehicle, leadhas been strongly linked to certain forms ofcancer. Many fuels contain benzene as a solvent. Unburned benzene has been strongly linkedto certain forms of cancer. If you live in anarea where you must fill your own gas tank,take precautions. These may include:
• standing upwind away from the filler noz- zle while refueling
• refueling only at gas stations with vaporrecovery systems that fully seal themouth of the filler neck during refueling
• wearing neoprene gloves while handling afuel filler nozzle.

Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for thevehicle.
NOTE
See page 369 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 300.
• 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.

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.
• 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 approvedby 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 page144 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 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 trunk, with the spare tire. Thiseyelet must be screwed into the positionsprovided on the right sides of either thefront or rear bumper (see illustration).
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 85 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 119 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 124 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.
