WARNING
Driving with the tailgate open: Driving
with the tailgate open could lead to poi- sonous exhaust gases entering the pas-senger compartment.
• If the tailgate must be kept open for any reason, proceed as follows:
• Close the windows
• Set the ventilation system control to airflow to floor, windshield and side win-dows and blower control to its highestsetting.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local lawsrequire that the service pump be marked indi-cating use of alcohols or ethers. However,there are areas in which the pumps areunmarked. If you are not sure whether there isalcohol or ethers in the gasoline you buy,check with the service station operator. Tomeet seasonal air quality standards, someareas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxy- genated" fuels; however, the octane ratingslisted on page 139 must still be met.
Alcohol – EthanolFuels containing up to 10% ethanol by vol- ume may be used. Ethanol may also be refer-red to as Ethyl alcohol, or "Gasohol". Ethers – MTBE: Fuels containing up to 15% MTBE may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practicecan result in vehicle performance deteriora-tion and can damage critical parts in the fuelsystem. Such damage may not be coveredunder the New Vehicle Limited Warranty.
Weight distribution affects handlingAt the specified curb weight your vehicle hasa 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 stability and reduces the risk of rear wheel skid. Remember that theseproperties can alter with the vehicle load. The heavier the load in the cargo area, the less the tendency to understeer.
Handling, roadholdingVehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the recom- mended pressure according to the vehicleload. See "Tire pressure" section. Loads should be distributed so that capacity weight or maximum permissible axle loadsare not exceeded.
Conserving electrical currentKeep the following in mind to help minimizebattery drain:
• When the engine is not running, avoid turning the ignition key to position
II (see
page 145). Many electrical systems (theaudio system, the optional infotainment/navigation systems, power windows, etc)will function with the ignition key in posi-tion I. This position reduces 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.
NOTE
A warning message will be displayed in the text window in the instrument panel whenthe battery charge is low.

WARNING
•Use the jack intended for the vehicle when changing a tire. For any otherjob, use stands to support the vehicle.
• The jack should be kept well-greasedand clean, and should not be dam-aged.
• Be sure the jack is on a firm, level,non-slippery surface.
• No objects should be placed betweenthe base of jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
• The jack must correctly engage thejack attachment.
• Never allow any part of your body tobe extended under a vehicle suppor-ted by a jack.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is run-ning. Never let the vehicle roll to a stop withthe engine switched off. If the power brakes are not working, consid- erably higher pressure will be required on thebrake pedal to compensate for the lack ofpower assistance. This can happen for exam- ple when towing your vehicle or if the engineis switched off when the vehicle is rolling. Thebrake pedal feels harder than usual.
Water on brake discs and brake pads
affects braking
Driving in rain and slush or passing throughan automatic car wash can cause water tocollect on the brake discs and pads. This willcause a delay in braking effect when thepedal is depressed. To avoid such a delaywhen the brakes are needed, depress thepedal occasionally when driving through rain,slush etc. This will remove the water from thebrakes. Check that brake application feelsnormal. This should also be done after wash-ing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strainwhen driving in mountains or hilly areas, orwhen towing a trailer. Vehicle speed is usuallyslower, which means that the cooling of thebrakes is less efficient than when driving onlevel roads. To reduce the strain on thebrakes, shift into a lower gear and let theengine help with the braking. Do not forgetthat, if you are towing a trailer, the brakes willbe subjected to a greater than normal load.
Anti-lock brakes (ABS)If the ABS warning lamp lights up there is a
malfunction in the ABS system (the standardbraking system will however function) and thevehicle should be driven cautiously to atrained and qualified Volvo service technicianfor inspection. The Anti-lock Braking System(ABS) helps to improve vehicle control (stop-ping and steering) during severe braking con-ditions by limiting brake lockup. When thesystem "senses" impending lockup, brakingpressure is automatically modulated in orderto help prevent lockup, which could lead to askid. The system performs a self-diagnostic test when the engine is started and when thevehicle first reaches a speed of approxi- mately 12 mph (20 km/h). The brake pedal
will pulsate several times and a sound may be audible from the ABS control module. This isnormal. To obtain optimal effect from the ABS sys- tem, constant pressure should be kept on thebrake pedal. Do not pump the brake pedal. The switching of the ABS modulator will be audible and the brake pedal will pulsate dur-ing braking. Please be aware that ABS doesnot increase the absolute braking potential ofthe vehicle. While control will be enhanced,ABS will not shorten stopping distances onslippery surfaces.

Dynamic Stability Traction Control (DSTC)
The stability system consists of a number of functions designed help reduce wheel spin,counteract skidding, and to generally helpimprove directional stability.
NOTE
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel spin by transferring power from a drivewheel that begins to lose traction to thewheel on the opposite side of the vehicle (onthe same axle). TC is most active at low speeds.This is one of DSTC's permanent functions and cannot be switched off.
Spin control (SC)The spin control function is designed to helpprevent the drive wheels from spinning whilethe vehicle is accelerating. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily switch off this function for maxi-mum tractive force.
Temporarily switching off Spin control1. Turn the thumbwheel (1) on the left-side
steering wheel lever until the DSTC menu
is displayed.
2. Hold down the RESET button (2) to tog-
gle between
DSTC ON or DSTC SPIN
CONTROL OFF.
NOTE
• The message DSTC SPIN CONTROL
OFF indicates that the stability sys-
tem's spin control function has tempo- rarily been switched off.
• The stability control indicator light willilluminate and remain on until spincontrol has been reactivated.
• The spin control function is automati-cally enabled each time the engine isstarted.
•
DSTC ON indicates that all system
functions are active.
Active Yaw Control (AYC)This function helps maintain directional stabil- ity, for example when cornering, by brakingone or more of the wheels if the vehicleshows a tendency to skid or slide laterally. This is one of DSTC's permanent functions
and cannot be switched off.
WARNING
The car's handling and stability characte- ristics will be altered if the DSTC systemfunctions have been disabled.

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.

09 Maintenance and servicing

Belt check
Check the belt regularly to make sure it is in good condition and is clean. A worn or dirtybelt can cause poor cooling and low alterna-tor output as well as impair the operation ofthe power steering and the air conditioningunit.
NOTE
The drive belt is equipped with a self-ten- sioning mechanism and requires noadjustment between changes.
WARNING
The engine must not be running when this check is performed.
Check coolant level
The cooling system must be filled with cool- ant and not leak to operate at maximum effi-ciency. Check the coolant level regularly. Thelevel should be between the MAX and MIN
marks on the expansion tank. The checkshould be made with particular thoroughnesswhen the engine is new or when the coolingsystem has been drained. Do not remove the filler cap other than for topping up with coolant. Frequent removalmay prevent coolant circulation between the engine and the expansion tank during enginewarm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. Do not top off with water only. This reduces the rust-protective and antifreeze qualities ofthe coolant and has a lower boiling point. Itcan also cause damage to the cooling systemif it should freeze. Top off with Volvo GenuineCoolant/Antifreeze only (a 50/50 mix of waterand antifreeze.
CAUTION
The cooling system must always be kept filled to the correct level. If it is not keptfilled, there can be high local temperaturesin the engine which could result in dam-age. Different types of antifreeze/coolantmay not be mixed.
WARNING
•
Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
