ECO*
Eco is a function 10
developed by Volvo to give
the driver the opportunity to actively drive more economically and to help reduce fuel consump-tion.
IntroductionWhen Eco is activated, the fol- lowing functions are modified:
• The automatic transmission's shifting points
• The engine management system and accel- erator pedal response
• Stop/stop function (Start/Stop – introduction(p. 268)): the engine can auto-stop beforethe vehicle has come to a full stop
• Eco Coast functionality is activated: enginebraking 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 the function ofcertain current-consuming systems will bereduced. 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 deacti- vated and must be reactivated each time theengine is started (with the exception of certainengines). The
ECO symbol will be displayed in the instru-
ment panel and the indicator light in the ECO
button will be on when Eco is activated.
Eco on or offWhen ECO is deactivated, theECO symbol will not be dis-
played in the instrument panel and the indicator light in the ECO button will be off. The
function will remain deactivated until the button is pressedagain.
Eco CoastEco Coast is an integral part of the Eco function and essentially deactivates engine braking, allow-ing the vehicle to roll freely.
NOTE
To function optimally, Eco Coast should pri- marily be used when the vehicle can coast asfar as possible.
When the driver releases the accelerator pedal, the transmission is automatically disengagedfrom the engine and engine rpm will be reducedto the idle level (approx. 700-800 rpm), whichhelps reduce fuel consumption.

* Option/accessory, for more information, see Introduction.
274 This feature is primarily intended to be used in driving situations where a decrease in speed isexpected, such as when entering a zone with alower speed limit. Eco Coast enables proactive driving with as little braking as possible.
Combinations of On and Off
Depending on the driving situation, Eco can be used in different ways to help reduce fuel con-sumption:
• With Eco activated
: this enables Eco Coast,
which allows the vehicle to roll freely for as
far as possible when the driver releases the
accelerator pedal (e.g., when approaching atraffic light or intersection).
or
• With Eco deactivated
: engine braking can
be used when the vehicle will only roll for
a short distance (in heavy traffic, etc.) or
when driving down hills .
To help keep fuel consumption as low as possi-ble, Eco Coast should not be used in traffic situa-tions where the brakes have to be used fre-quently.
Activating Eco Coast
Eco Coast is activated when the accelerator pedal is released completely if:
• Eco is activated
• The gear selector is in
D •
The vehicle's speed is between approxi-mately 40–85 mph (65–140 km/h). Alwaysobserve posted speed limits
• The gradient of a down-slope is less thanapproximately 6%
Deactivating
Eco Coast
In certain situations, it may be advisable to switch off the Eco Coast function, such as:
• When driving down steep hills, in order to uti-lize engine braking
• Prior to passing another vehicle, in order todo so as safely as possible
Deactivating Eco Coast (and reactivating enginebraking) can be done in the following ways: • Press the
ECO button on the center console
• Move the gear selector to the manual "
S+/–"
position
• Change gears using the steering wheel pad- dles
*
• Press the brake or accelerator pedal
Eco Coast limitationsThis function will not be available if:
• Cruise control is activated
• The gradient of a down-slope is more than approximately 6%
• The steering wheel paddles
* are used to
manually change gears •
The engine and/or transmission have notreached their normal operating temperature
• The gear selector is moved from
D to the
manual " S+/–" position
• The vehicle's speed is not within the40–85 mph (65–140 km/h). interval
Additional information and settings
Other ECO-related settings can be made in the vehicle's
MY CAR menu. See My Car – introduc-
tion (p. 77) for more information.

All Wheel Drive (AWD)Your Volvo can be equipped with permanent All Wheel Drive, which means that power is distrib-uted automatically between the front and rearwheels.
Under normal driving conditions, most of the engine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe 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 also illu-minate in the instrument panel. If this occurs,have the system checked by a trained andqualified Volvo service technician.

Hill Descent Control (HDC) – introduction
HDC is a type of automatic engine brake and makes it possible to increase or decrease thevehicle's speed on downhill gradients using onlythe accelerator pedal, without applying thebrakes. The brake system functions automaticallyto maintain a low and steady speed.
IntroductionNormally, when the accelerator pedal is released while driving down hills, the vehicle's speed slowsas the engine runs at lower rpm (the normalengine braking effect). However, if the downhillgradient becomes steeper and if the vehicle iscarrying a load, speed increases despite theengine braking effect. In this situation, the brakesmust be applied to reduce the 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. The driver hasfull responsibility for driving in a safe manner.

Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect onthe brake discs and pads. This will cause a delayin braking effect when the pedal is depressed. Toavoid such a delay when the brakes are needed,depress the pedal occasionally when drivingthrough rain, slush, etc. This will remove the waterfrom the brakes. Check that brake applicationfeels normal. This should also be done afterwashing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain whendriving in mountains or hilly areas, or when towinga trailer. Vehicle speed is usually slower, whichmeans that the cooling of the brakes is less effi-cient than when driving on level roads. To reducethe strain on the brakes, shift into a lower gearand let the engine help with the braking. Do notforget that if you are towing a trailer, the brakeswill be subjected to a greater than normal load.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.

Anti-lock braking system (ABS) The ABS system helps to improve vehicle con- trol (stopping and steering) during severe brak-ing conditions by limiting brake lockup.
When the system "senses" impending lockup, braking pressure is automatically modulated inorder to help prevent lockup that could lead to askid. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.

Brake lights The brake lights come on automatically when the brakes are applied.
Adaptive brake lights
The adaptive brake lights activate in the event of sudden braking or if the ABS system is activated.This function causes an additional taillight oneach side of the vehicle to illuminate to help alertvehicles traveling behind. The adaptive brake lights activate if:
• The ABS system activates for more than approximately a half second
• In the event of sudden braking while thevehicle is moving at speeds above approxi-mately 6 mph (10 km/h).
When the vehicle has come to a stop, the brakelights and additional taillights remain on for aslong as the brake pedal is depressed or untilbraking force on the vehicle is reduced.

Emergency Brake Assistance (EBA)
EBA is designed to provide full brake effect immediately in the event of sudden, hard brak-ing.
Emergency Brake AssistanceThe EBA system is activated by the speed with which the brake pedal is depressed. When the EBA system is activated, the brake pedal will go down and pressure in the brake sys-tem immediately increases to the maximum level.Maintain full pressure on the brake pedal in orderto utilize the system completely. EBA is automati-cally deactivated when the brake pedal isreleased.

STARTING AND DRIVING

Driving through water
The vehicle should be driven with extreme cau- tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to a depth of approximately 10 in. (25 cm), (V60Cross Country: approximately 12 in. (30 cm)) atwalking speed to help prevent water from enter-ing the differential and the transmission. Waterreduces the oil's lubricating capacity and mayshorten the service life of these components.
• 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 dangerous and itmay also be difficult to determine theactual depth of the water.
• If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.
CAUTION
•Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than approximately 10 in.(25 cm), (V60 Cross Country: approxi-mately 12 in. (30 cm)), water may enterthe differential and the transmission. Thisreduces the oil's lubricating capacity andmay shorten the service life of thesecomponents.
• Damage to any components, the engine,transmission, turbo-charger, differential orits internal components caused by flood-ing, vapor lock or insufficient oil is notcovered under warranty.
• Do not allow the vehicle to stand in waterup to the door sills longer than absolutelynecessary. This could result in electricalmalfunctions.
• If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water.

Engine and cooling system
Under special conditions, for example when driv- ing in hilly terrain, extreme heat or with heavyloads, there is a risk that the engine and coolingsystem will overheat.
Proceed as follows to avoid overheating the engine.
• Maintain a low speed when driving with atrailer up long, steep hills. For information,see Towing a trailer (p. 292)
• Do not turn the engine off immediately whenstopping after a hard drive.
WARNING
The cooling fan may start or continue to oper- ate (for up to 6 minutes) after the engine hasbeen switched off.
• Remove any auxiliary lights from in front of the grille when driving in hot weather condi-tions.
• Do not exceed engine speeds of 4500 rpm ifdriving with a trailer in hilly terrain. The oiltemperature could become too high.

Driving in cold weather
Check your vehicle before the approach of cold weather.
The following advice is worth noting:
• Make sure that the engine coolant (p. 341) contains 50 percent antifreeze. Any othermixture will reduce freeze protection. Thisgives protection against freezing down to–31 °F (–35 °C). The use of "recycled" anti-freeze is not approved by Volvo. Differenttypes of antifreeze must not be mixed.
• Volvo recommends using only genuine Volvoantifreeze in your vehicle's radiator.
• Try to keep the fuel tank well filled – thishelps prevent the formation of condensationin the tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
• The viscosity of the engine oil is important.Oil with low viscosity (thinner oil) improvescold-weather starting as well as decreasingfuel consumption while the engine is warm-ing up. Full synthetic 0W-30 oil is recom-mended for driving in areas with sustainedlow temperatures.
• The load placed on the battery is greater dur-ing the winter since the windshield wipers,lighting, etc., are used more often. Moreover,the capacity of the battery decreases as thetemperature drops. In very cold weather, apoorly charged battery can freeze and be damaged. It is therefore advisable to checkthe state of charge more frequently andspray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tires onall four wheels for winter driving, see Snowtires/studded tires (p. 316).
• To prevent the washer fluid (p. 354)reservoirfrom freezing, add washer solvents contain-ing antifreeze. This is important since dirt isoften splashed on the windshield during win-ter driving, requiring the frequent use of thewashers and wipers. Volvo Washer Solventshould be diluted as follows: Down to 14 °F(–10 °C): 1 part washer solvent and 4 partswater Down to 5 °F (–15 °C): 1 part washersolvent and 3 parts water Down to 0 °F(–18 °C): 1 part washer solvent and 2 partswater Down to –18 °F (–28 °C): 1 partwasher solvent and 1 part water.
• Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.
Refueling – fuel requirements
Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (detergent
additives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddrivability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo does not recommend the use of exter- nal fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. andCanadian regulations require that pumps deliver-ing unleaded gasoline be labeled "UNLEADED".Only these pumps have nozzles which fit yourvehicle's filler inlet. It is unlawful to dispense lea-ded fuel into a vehicle labeled "unleaded gaso-line only". Leaded gasoline damages the three-way catalytic converter and the heated oxygensensor system. Repeated use of leaded gasolinewill lessen the effectiveness of the emission con-trol system (p. 290) and could result in loss ofemission warranty coverage. State and local vehi-

cle inspection programs will make detection of misfueling easier, possibly resulting in emissiontest failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl(MMT). If such fuels are used, your EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle to a trained and qualified Volvoservice technician for service.
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 laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. To meet seasonal air quality standards,some areas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxygen- ated" fuels; however, the octane ratings (p. 287)listed must still be met.
Alcohol – Ethanol
Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to asEthyl 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 practice canresult in vehicle performance deterioration andcan damage critical parts in the fuel system. Suchdamage may not be covered under the NewVehicle Limited Warranty.
Refueling – octane rating Volvo recommends premium fuel for best per- formance, but using 87 octane
