ECO*
Eco is a function 10
developed by Volvo to give
the driver the opportunity to actively drive more economically and to help reduce fuelconsumption.
IntroductionWhen Eco is activated, thefollowing functions are modi-fied:
• The automatic transmission's shifting points
• The engine management system andaccelerator pedal response
• Stop/stop function (Start/Stop – introduc-tion (p. 256)): the engine can auto-stopbefore the vehicle has come to a full stop
• Eco Coast functionality is activated:engine braking is disabled
• Climate system settings: certain functions(e.g., air conditioning) will be temporarilyreduced or deactivated
NOTE
When Eco is activated, several climate system parameters are changed and thefunction of certain current-consuming sys-tems will be reduced. Some of these functions can be restarted manually but full functionality will not berestored until Eco is deactivated.
Function
ECO On/Off button in the center console
ECO symbol in the instrument panel
When the engine is switched off, ECO is deactivated and must be reactivated eachtime the engine is started (with the exceptionof certain engines). The
ECO symbol will be displayed in the
instrument panel and the indicator light in the ECO button will be on when Eco is activated.
Eco on or offWhen ECO is deactivated, the ECO symbol will not be
displayed in the instrument panel and the indicator lightin the ECO button will be off.
The function will remaindeactivated until the buttonis pressed again.
Eco CoastEco Coast is an integral part of the Eco func- tion and essentially deactivates engine brak-ing, allowing the vehicle to roll freely.
NOTE
To function optimally, Eco Coast should primarily be used when the vehicle cancoast as far as possible.
When the driver releases the accelerator pedal, the transmission is automatically dis-engaged from the engine and engine rpm willbe reduced to the idle level(approx. 700-800 rpm), which helps reducefuel consumption.

All Wheel Drive (AWD)
Your Volvo can be equipped with permanent All Wheel Drive, which means that power isdistributed automatically between the frontand rear wheels.
Under normal driving conditions, most of the engine's power is directed to the frontwheels. However, if there is any tendency forthe front wheels to spin, an electronicallycontrolled coupling distributes power to thewheels that have the best traction.
NOTE
The message AWD disabled Service
required will be appear in the information
display if an electrical fault should occur in the AWD system. A warning light will alsoilluminate in the instrument panel. If thisoccurs, have the system checked by atrained and qualified Volvo service techni-cian.

Hill Descent Control (HDC) 12
–
introduction
HDC is a type of automatic engine brake and makes it possible to increase or decrease thevehicle's speed on downhill gradients usingonly the accelerator pedal, without applyingthe brakes. The brake system functions auto-matically to maintain a low and steady speed.
IntroductionNormally, when the accelerator pedal isreleased while driving down hills, the vehicle'sspeed slows as the engine runs at lower rpm(the normal engine braking effect). However, ifthe downhill gradient becomes steeper and ifthe vehicle is carrying a load, speed increasesdespite the engine braking effect. In this sit-uation, the brakes must be applied to reducethe vehicle's speed. HDC is particularly useful when driving down steep hills with rough surfaces, and where theroad may have slippery patches.
WARNING
HDC does not function in all situations, and is a supplementary braking aid. Thedriver has full responsibility for driving in asafe manner.

Brakes – general
The brake system is a hydraulic system con- sisting of two separate brake circuits. If aproblem should occur in one of these circuits,it is still possible to stop the vehicle with theother brake circuit. If the brake pedal must be depressed farther than normal and requires greater foot pres-sure, the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault hasoccurred. If this light comes on while driving or braking, stop immediately and check the brake fluidlevel in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal – do not pump thebrakes.
WARNING
If the fluid level is below the
MIN mark in
the reservoir or if a brake system message is shown in the information display: DO
NOT DRIVE . Have the vehicle towed to a
trained and qualified Volvo service techni-cian and have the brake system inspected.
Brake pad inspectionOn vehicles equipped with a jack*, the condi- tion of the brake pads can be checked byraising the vehicle (see Changing a wheel –removing wheel (p. 291) for informationabout using the jack and removing a wheel)and performing a visual inspection of thebrake pads.
WARNING
• If the vehicle has been driven immedi- ately prior to a brake pad inspection,the wheel hub, brake components,etc., will be very hot. Allow time forthese components to cool before car-rying out the inspection.
• Apply the parking brake and put thegear selector in the Park (
P) position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.

Tires – storage and age
When storing complete wheels (tires mounted on rims), they should be suspended off thefloor or placed on their sides on the floor.
New Tires
Remember that tires are perishable goods. Asof 2000, the manufacturing week and year(Department of Transportation (DOT) stamp)will be indicated with 4 digits (e.g., 1513means that the tire illustrated was manufac-tured during week 15 of 2013).
Tire ageTires degrade over time, even when they are not being used. It is recommended that tiresgenerally be replaced after 6 years of normalservice. Heat caused by hot climates, fre-quent high loading conditions or Ultra Violet(U.V.) exposure can accelerate the agingprocess. The temporary spare
1
should also
be replaced at 6-year intervals, even if it hasnever been used. A tire's age can be determined by the DOT stamp on the sidewall (see the illustration). A tire with e.g., visible cracks or discoloration should be replaced immediately.
Storing wheels and tiresWhen storing completes wheels (tires moun-ted on rims), they should be suspended offthe floor or placed on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but shouldnot be suspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never bestored in close proximity to solvents, gaso-line, oils, etc.
WARNING
• The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unap-proved wheel/tire size combinationscan negatively affect your vehicle'sstability and handling.
• Any damage caused by installation ofunapproved wheel/tire size combina-tions will not be covered by your newvehicle warranty. Volvo assumes noresponsibility for death, injury, orexpenses that may result from suchinstallations.

Changing a wheel – spare wheel
Wheel changes should always be carried out correctly.
Spare tire
The spare tire in your vehicle2
is called a
"Temporary Spare". Recommended tire pressure (see the placard on the B-pillar or on the fuel filler door) shouldbe maintained irrespective of which positionon the vehicle the temporary spare tire isused on. In the event of damage to this tire, a new one can be purchased from your Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Road holding andhandling may be affected with the "Tem-porary Spare" in use. Do not exceed50 mph (80 km/h).
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tireother than the one that came with the vehi-cle. The use of different size wheels canseriously damage your car's transmission.
Spare wheelThe spare wheel is only intended for tempo- rary use. Replace it with a normal wheel assoon as possible. The car's handling may bealtered by the use of the spare wheel. Thecorrect tire pressure for the spare wheel isstated in the tire pressure table, see Tire infla-tion – pressure table (p. 300) and in the tireinflation placard on the driver's side doorjamb at the rear of the driver's door opening.
WARNING
Current legislation prohibits the use of the “Temporary Spare” tire other than as atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Road holding andhandling may be affected with the “Tem-porary Spare” in use.
CAUTION
The vehicle must never be driven with more than one temporary spare wheel.
The spare wheel is located in the spare wheel well with the rim side down. There are twofoam blocks, one under the spare wheel andone over/inside. The upper one contains alltools. The same bolt runs through to secure the spare wheel and the foam blocks.

• Cold tires
: The tires are considered to be
cold when they have the same tempera-ture as the surrounding (ambient) air. Thistemperature is normally reached after thevehicle has been parked for at least3 hours.
Tire specifications – Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETYREQUIREMENTS IN ADDITION TO THESEGRADES .
Quality grades can be found, where appli-cable, on the tire sidewall between thetread shoulder and maximum sectionwidth. For example: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when tes-ted under controlled conditions on a specifiedgovernment test course. For example, a tiregraded 150 would wear one and one half(1 ½) times as well on the government courseas a tire graded 100. The relative perform-ance of tires depends upon the actual condi-tions of their use, however, and many departsignificantly from the norm due to variation indriving habits, maintenance practices and dif-ferences in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest,are AA, A, B, and C, as measured under con-trolled conditions on specified governmenttest surfaces of asphalt and concrete. A tiremarked C may have poor traction perform- ance. The traction grade assigned to this tireis based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering(turning) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance tothe generation of heat and its ability to dissi-pate heat when tested under controlled con-ditions on a specified indoor laboratory testwheel. Sustained high temperature can causethe material of the tire to degenerate andreduce tire life, and excessive temperaturecan lead to sudden tire failure. The grade Ccorresponds to a minimum level of perform-ance that all passenger vehicle tires mustmeet under the Federal Motor Safety Stand-ard No. 109. Grades B and A represent higherlevels of performance on the laboratory testwheel than the minimum required by law.

Snow tires/studded tires4
Owners who live in or regularly commute through areas with sustained periods of snowor icy driving conditions are strongly advisedto fit suitable winter tires to help retain thehighest degree of traction.
Tires for winter use:
•
It is important to install winter tires on all four wheels to help retain traction duringcornering, braking, and accelerating. Fail-ure to do so could reduce traction to anunsafe level or adversely affect handling.
• Do not mix tires of different design as thiscould also negatively affect overall tireroad grip.
• Winter tires wear more quickly on dryroads in warm weather. They should beremoved when the winter driving seasonhas ended.
• Studded tires should be run-in 300 – 600 miles (500 – 1000 km) during whichthe vehicle should be driven as smoothlyas possible to give the studs the opportu-nity to seat properly in the tires. The tiresshould have the same rotational directionthroughout their entire lifetime.
NOTE
Please consult state or provincial regula- tions restricting the use of studded wintertires before installing such tires.
Tire pressure monitoring - introduction
Volvo provides two different systems to moni- tor tire pressure: Tire Pressure MonitoringSystem (TPMS) or Tire Monitor.
Determining which tire monitoring system is in your vehicle
To see which system is installed in your vehi- cle, press the
MY CAR button on the center
console. Go to
SettingsCar settings.
• If your vehicle has a menu called
Tire
monitoring, see Tire Monitor - introduc-
tion (p. 310).
• If your vehicle has a menu called
Tire
pressure, see Tire Pressure Monitoring
System (TPMS) – general information (p. 306).
IntroductionEach tire, including the spare (if provided), should be checked monthly when cold andinflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different sizethan the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure forthose tires.) As an added safety feature, your vehicle hasbeen equipped with a tire pressure monitor-ing system that illuminates a low tire pressure telltale (
) when one or more of your tires
is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates,you should stop and check your tires as soonas possible, and inflate them to the properpressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead totire failure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle's handling and stopping ability.Please note that a tire pressure monitoringsystem is not a substitute for proper tiremaintenance, and it is the driver's responsi-bility to maintain correct tire pressure, even ifunder-inflation has not reached the level totrigger illumination of the system's low tirepressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. Themonitoring system's malfunction indicator iscombined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minuteand then remain continuously illuminated.This sequence will continue upon subsequentvehicle start-ups as long as the malfunction
