* Option/accessory, for more information, see Introduction.185
When does BLIS function
The system functions when your vehicle is moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:The system reacts when you pass another vehicle at a speed of up to 6 mph (10 km/h)faster than that vehicle.
When you are passed by another
vehicle:
The system reacts if your vehicle is passed by another vehicle at a speed of up to 43 mph(70 km/h) faster than your vehicle.
WARNING
• BLIS does not function in sharp curves.
• BLIS does not function when yourvehicle is backing up.
• If you are towing a wide trailer, thismay prevent the BLIS cameras fromdetecting other vehicles in adjacentlanes.
How BLIS functions in daylight and darkness
DaylightBLIS reacts to the
shape of surrounding vehi-
cles. The system is designed to help detect motor vehicles such as cars, trucks, buses, motorcycles, etc.
DarknessBLIS reacts to the
headlights of surrounding
vehicles. In order to be detected by BLIS, a vehicle in the blind area must have its head-lights on. This means, for example, that thesystem will not detect a trailer without head-lights that is being towed behind a car ortruck.
WARNING
• BLIS does not react to cyclists or mopeds.
• BLIS does not react to vehicles thatare standing still.
• The BLIS cameras have the same limi-tation as the human eye. In otherwords, their "vision is impaired" byadverse weather conditions such asheavy snowfall, intense light directlyinto the camera, dense fog, etc.
LimitationsIn certain situations, the BLIS indicator light(s) may illuminate even when there are no othervehicles in the area monitored by the system.
NOTE
If the BLIS indicator lights illuminate occa- sionally even when there are no other vehi-cles in the blind area, this does not indi-cate a fault in the system. In the event of a fault,
Blind spot syst.
Service required will be displayed.
The following are several examples of situa- tions in which the BLIS indicator light(s) mayilluminate even when there are no other vehi-cles in the area monitored by the system.

* Option/accessory, for more information, see Introduction.199
Introduction
Air conditioningThe vehicle is equipped with Electronic Cli- mate Control (ECC). The climate control sys-tem cools, heats or dehumidifies the air in thepassenger compartment.
NOTE
• The air conditioning can be switched off, but to ensure the best possible cli-mate comfort in the passenger com-partment and to prevent the windowsfrom misting, it should always be on.
• In warm weather, a small amount ofwater may accumulate under the carwhen it has been parked. This water iscondensation from the A/C systemand is normal.
Sensor location
•
The sunlight sensor is located on the top side of the dashboard.
NOTE
The sunlight sensor monitors which side of the car that is most exposed to sunlight.This can mean that the temperature maydiffer between the right and left-side airvents, even if the temperatures set for bothsides of the passenger compartment arethe same.
•The temperature sensor for the passen- ger compartment is located below the cli-mate control panel.
• The outside (ambient) temperature sensoris located on the door mirror.
• The humidity sensor* is located in theinterior rearview mirror.
NOTE
Do not cover or block the sensors with clothing or other objects.
Side windows and moonroofTo ensure that the air conditioning works optimally, the side windows, and the optionalmoonroof should be closed.
Fog on the inside of the windowsThe defroster function should be used toremove fog or mist from the inside of the win-dows. Keeping the windows clean with acommercially available window washing spray will also help prevent fogging or mist-ing.
Vents in the parcel shelf
NOTE
The air vents at the rear of the parcel shelf should never be obstructed.
Temporary shut-off of the air conditioning
The air conditioning is momentarily disen- gaged during full acceleration or when drivinguphill with a trailer. This may result in a tem-porary increase in cabin temperature.
Ice and snowAlways keep the air intake grille at the base ofthe windshield free of snow.
Climate system maintenanceSpecial tools and equipment are required tomaintain and carry out repairs on the climatesystem. Work of this type should only bedone by a trained and qualified Volvo servicetechnician.
RefrigerantVolvo cares about the environment. The airconditioning system in your car contains aCFC-free refrigerant – R134a. This substancewill not deplete the ozone layer. The air con-

or maximum permissible axle loads are not exceeded.
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.

Octane rating
Minimum octane
G028920
Typical pump octane labelVolvo recommends premium fuel for best performance, but using 87 octane 1
or above
will not affect engine reliability.
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.
WARNING
Never carry a cell phone that is
switched
on while refueling your vehicle. If the
phone rings, this may cause a spark that could ignite gasoline fumes, resulting infire and injury.
WARNING
Carbon monoxide is a poisonous, color- less, and odorless gas. It is present in allexhaust gases. If you ever smell exhaustfumes inside the vehicle, make sure thepassenger compartment is ventilated, andimmediately return the vehicle to a trainedand qualified Volvo service technician forcorrection.

Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for thevehicle.
NOTE
See page 359 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 293.
• 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. See also page 131 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 page136 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 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 is

temporarily reduced. As the swaying motion begins 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.

Loads
Properly loading your vehicle will provide maximum return of vehicle design perform-ance. Before loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or withouta trailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weightThe weight of the vehicle including a full tankof fuel and all standard equipment. It doesnot include passengers, cargo, or optionalequipment.
Capacity weightAll weight added to the curb weight, includingcargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
NOTE
For trailer towing information, please refer to the section "Towing a trailer" on page279.
Permissible axle weightThe maximum allowable weight that can be carried by a single axle (front or rear). Thesenumbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axlemust never exceed its maximum permissibleweight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-gers.
NOTE
•The location of the various labels in your vehicle can be found on page356.
• A table listing important weight limitsfor your vehicle can be found on page359.
Steps for Determining Correct Load Limit
1. Locate the statement "the combined
weight of occupants and cargo should never exceed XXX pounds" on your vehi-cle's placard. 2. Determine the combined weight of the
driver and passengers that will be ridingin your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kilo-grams or XXX pounds.
4. The resulting figure equals the available amount of cargo and luggage loadcapacity. For example, if the "XXX"amount equals 1400 lbs. and there will befive 150 lb. passengers in your vehicle,the amount of available cargo and lug-gage load capacity is 650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of lug- gage and cargo being loaded on the vehi-cle. That weight may not safely exceedthe available cargo and luggage loadcapacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual 1
to deter-
mine how this reduces the available cargo and luggage load capacity of yourvehicle.
