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.
Use of AdditivesWith the exception of gas line antifreeze dur- ing winter months, do not add solvents, thick-eners, or other store-bought additives to yourvehicle's fuel, cooling, or lubricating systems.Overuse may damage your engine, and someof these additives contain organically volatilechemicals. Do not needlessly expose yourselfto these chemicals.

Fuel vapor expands in hot weather. Open the filler cap slowly. After refueling, close the fuel filler cap by turning it clockwise until it clicks into place.
CAUTION
• Do not refuel with the engine run- ning 13
. Turn the ignition off or to posi-
tion I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
• Avoid overfilling the fuel tank. Do not press the handle on the filler nozzlemore than one extra time. Too muchfuel in the tank in hot weather condi-tions can cause the fuel to overflow.Overfilling could also cause damage tothe emission control systems.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle ifyou detect engine misfire, noticeable lossof power or other unusual operating con-ditions, such as engine overheating orbackfiring. A properly tuned engine willhelp avoid malfunctions that could dam-age the three-way catalytic converter.
• Do not park your vehicle over combusti-ble materials, such as grass or leaves,which can come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
• Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cat-alytic converter or exhaust system over-heating.
• Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehiclemay be illegal and can cause three-waycatalytic converter or exhaust systemoverheating. This includes: altering fuelinjection settings or components, alteringemission system components or location or removing components, and/or repea-ted use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readingsare fed into a control module that continu-ously monitors engine functions and controlsfuel injection. The ratio of fuel to air into theengine is continuously adjusted for efficientcombustion to help reduce harmful emis-sions.

Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions.
Economical driving conserves natural resources
Observe the following rules:
• Bring the engine to normal operating tem- perature as soon as possible by drivingwith a light foot on the accelerator pedalfor the first few minutes of operation. Acold engine uses more fuel and is subjectto increased wear.
• Whenever possible, avoid using the vehi-cle for driving short distances. This doesnot allow the engine to reach normaloperating temperature.
• Drive carefully and avoid rapid accelera-tion and hard braking.
• Use the transmission's Drive (
D) position
as often as possible and avoid using kick-down.

• Using the engine's optional Eco func- tion14
can help improve fuel economy. For
additional information, see ECO* (p. 248).
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load) in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snowor ice has ended.
• Note that roof racks, ski racks, etc,increase air resistance and also fuel con-sumption.
• At highway driving speeds, fuel consump-tion will be lower with the air conditioningon and the windows closed than with theair conditioning off and the windowsopen.
• Using the onboard trip computer's fuelconsumption modes can help you learnhow to drive more economically.
Other factors that decrease gas mileage are: • Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment Some of the above mentioned items and oth- ers are checked at the standard maintenanceintervals.
WARNING
Driving with the trunk open:
Driving with
the trunk open could lead to poisonous exhaust gases entering the passengercompartment. If the trunk must be keptopen for any reason, proceed as follows:
• Close the windows
• Set the ventilation system control to air flow to floor, windshield and side win-dows and the blower control to itshighest setting.
Handling and roadholdingAt the specified curb weight your vehicle has a tendency to understeer, which means thatthe steering wheel has to be turned morethan might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe trunk, the less the tendency to under-steer. •
Vehicle load, tire design and inflation pressure all affect vehicle handling.Therefore, check that the tires are inflatedto the recommended pressure according to the vehicle load. Loads should be dis-tributed so that capacity weight or maxi-mum permissible axle loads are notexceeded.

Towing a trailer
When towing a trailer, always observe the legal requirements of the state/province.
NOTE
For the maximum trailer and tongue weights recommended by Volvo, seeWeights (p. 357).
•All Volvo models are equipped with energy-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 Tire inflation – pressuretable (p. 285).
• 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 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.
• 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.
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%.

CAUTION
The maximum trailer weights listed are only applicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and thereforethe car's climbing ability are impairedbecause of the reduced air density, so themaximum trailer weight has to be reducedaccordingly. The weight of the vehicle andtrailer must be reduced by 10% for everyfurther 3,280 ft (1000 m) (or part thereof).When towing 5,950 lbs (2,700kg) hill incli-nation is restricted to 14%.
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 chains or wire must be correctlyfastened to the attachment points pro-vided in the trailer hitch on the vehicle.The safety chain or wire must never befastened to or wound around the tow-ing ball.
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 stability system. Forinformation on the stability system, see Stabil-ity system – introduction (p. 162)
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 also

be switched off (but will be on again the next 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 the
ignition slot 15
, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II. 2. The remote key must remain in the igni-
tion slot 16
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.
15Not necessary in vehicles with the optional keyless drive.

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. 73)
• 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.
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).

Tire Monitor - introduction
Tire Monitor uses the rotational speed of the tires in combination with signal analysis of theABS sensor signals to determine if they areproperly inflated. When a tire is under-inflated, its diameter (and consequently also its rotational speed)changes. By comparing the individual tireswith each other it is possible to determine ifone or more tires are under inflated. When low inflation pressure is detected or if the system is not functioning properly, TireMonitor will light up the tire pressure warning light (
) (also referred to as a telltale) in
the instrument panel and will display one of the following messages in the text window, for example:
Tire pressure low Check rear
right tire5 or Tire press. syst Service
required.
If two or more tires have low pressure or if the system cannot determine which tire has low pressure, a general text (
Tire pressure low
Check tires) will be displayed.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash forapproximately 1 minute and then remain illuminated.
Tire press. syst Service
required will be displayed.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance.For information on correct tire pressure,please refer to the tire inflation pressuretable (see Tire inflation – pressure table(p. 285)), the tire inflation pressure placardlocated on the driver's side B-pillar (thestructural member at the side of the vehi-cle, at the rear of the driver's door open-ing) or consult your Volvo retailer.

Calibrating Tire Monitor
In order for Tire Monitor to work correctly, tire pressure reference values must be set. Thismust be done each time wheels or tire pres-sures are changed.
Calibration1. Switch off the engine.
2. Inflate the tires to the desired pressure
(consult tire pressure placard located on the driver's side B-pillar (the structuralmember at the side of the vehicle) andput the ignition in mode II, see Ignition
