With fuel-efficient driving, the gauge shows a low value with the pointer in the green zone.
• With non-fuel-efficient driving, e.g. duringheavy braking or heavy acceleration, thegauge shows a high value.
The ECO gauge also has an indicator to showhow a reference driver would drive the car underthe same driving conditions. This is indicated withthe short pointer on the gauge.
Eco gauge in the 12-inch driver display.
Eco gauge in the 8-inch driver display.
ECO climate controlIn the Eco drive mode, ECO climate control is
activated automatically in the passenger com- partment in order to reduce energy consumption.
NOTE
When the ECO function is activated, several parameters in the climate control system'ssettings are changed, and several electricityconsumer functions are reduced. Certain set-tings can be reset manually, but full function-ality is only regained by switching off the ECO function or adapting
Individual* drive mode
with full climate functionality.
In the event of difficulties due to misting, press the button for max. defroster which has normalfunctionality.

Overloading the starter battery
The electrical functions in the car load the starter battery to varying degrees. Avoid using the igni-tion position II when the car is switched off.
Instead, use ignition position I - which uses less
power.
Also, be aware of different accessories that load the electrical system. Do not use functions whichuse a lot of power when the car is switched off.Examples of such functions are:
• ventilation fan
• headlamps
• windscreen wiper
• audio system (high volume).
If the starter battery voltage is low, the message
12 V Battery Low charge, will soon enter
power save mode is shown in the driver display.
The energy-saving function then shuts down cer- tain functions or reduces certain functions suchas the ventilation fan and/or audio system.
–In which case, charge the starter battery by starting the car and then running it for atleast 15 minutes - starter battery charging ismore effective during driving than runningthe engine at idling speed while stationary.

Preparations for a long trip
Before a driving holiday or some other type of long journey, it is important to check the car'sfunctions and equipment particularly carefully.
Check that:
• the engine is working normally and that fuel consumption is normal
• there are no leaks (fuel, oil or other fluid)
• all bulbs are working
• the tyres have sufficient tread depth andpressure
• a warning triangle and high-visibility vest arelocated in the car - legally required in certaincountries
• the wiper blades are in good condition.

Winter driving
For winter driving it is important to perform cer- tain checks of the car in order to ensure that itcan be driven safely.
Check the following in particular before the cold season:
• The engine coolant must contain 50% glycol.This mixture protects the engine againstfrost erosion down to approximately –35 °C.To avoid health risks, different types of glycolmust not be mixed.
• The fuel tank must be kept filled to preventcondensation.
• Engine oil viscosity is important. Oils withlower viscosity (thinner oils) facilitate startingin cold weather and also reduce fuel con-sumption while the engine is cold. Readmore about suitable oils in the section"Adverse driving conditions for engine oil".
IMPORTANT
Low viscosity oil must not be used for hard driving or in hot weather.
• The condition of the starter battery and charge level must be inspected. Coldweather places great demands on the starter battery and its capacity is reduced by thecold.
• Use washer fluid with antifreeze to avoid iceforming in the washer fluid reservoir.
Slippery driving conditionsTo achieve optimum roadholding Volvo recom-mends using winter tyres on all wheels if there isa risk of snow or ice.
NOTE
The use of winter tyres is a legal requirement in certain countries. Studded tyres are notpermitted in all countries.
Practise driving on slippery surfaces under con- trolled conditions to learn how the car reacts.

Handling of fuel
Do not use fuel with a lower quality than that rec- ommended by Volvo, as this will negatively affectengine power and fuel consumption.
WARNING
Always avoid inhaling fuel vapour and getting fuel splashes in the eyes. In the event of fuel in the eyes, remove any contact lenses and rinse the eyes in plenty ofwater for at least 15 minutes and seek medi-cal attention. Never swallow fuel. Fuels such as petrol, bioe- thanol and mixtures of them and diesel arehighly toxic and could cause permanent injuryor be fatal if swallowed. Seek medical atten-tion immediately if fuel has been swallowed.
WARNING
Fuel which spills onto the ground can be igni- ted. Switch off the fuel-driven heater before star- ting to refuel. Never carry an activated mobile phone when refuelling. The ring signal could cause sparkbuild-up and ignite petrol fumes, leading tofire and injury.
14 Only applies to a car with diesel engine.

Petrol
Petrol is a type of engine fuel that is intended for cars with a petrol engine.
Only use petrol from well-known producers. Never use fuel of dubious quality. The petrol mustfulfil the EN 228 standard.
IMPORTANT
• Fuel that contains up to 10 percent by volume ethanol is permitted.
• EN 228 E10 petrol (max10 percent by volume ethanol) isapproved for use.
• Ethanol higher than E10 (max.10 percent by volume ethanol) is not per-mitted, e.g. E85 is not permitted.
Octane rating
•95 RON can be used for normal driving.
• 98 RON is recommended for optimum per- formance and minimum fuel consumption.
When driving in temperatures above +38 °C, fuelwith the highest possible octane rating is recom-mended for optimum performance and fuel econ-omy.
IMPORTANT
• Use only unleaded petrol to avoid damag- ing the catalytic converter.
• Fuel containing metallic additives mustnot be used.
• Do not use any additives which have notbeen recommended by Volvo.

Diesel Diesel is a type of engine fuel that is intended for cars with a diesel engine.
Only use diesel fuel from well-known producers. Never use fuel of dubious quality. Diesel fuelmust fulfil the EN 590 or SS 155435 standard.Diesel engines are sensitive to contaminants inthe fuel, such as excessively high volumes of sul-phur and metals. At low temperatures (lower than 0 °C) a paraffin precipitate may form in the diesel fuel, which maylead to ignition problems. The fuel qualities thatare sold must be adapted for season and climatezone, but for extreme weather conditions, old fuelor moving between climate zones, paraffin precip-itate may occur. The risk of condensation in the fuel tank is reduced if the tank is kept well filled. When refuelling, check that the area around the fuel filler pipe is clean. Avoid spilling fuel onto thepaintwork. Wash off any spillage with detergentand water.
IMPORTANT
Diesel fuel must: •fulfil the EN 590 and/or SS 155435 standards
• have a sulphur content not exceeding10 mg/kg
• have a maximum of 7 vol % FAME 15
(B7).
IMPORTANT
Diesel type fuels that must not be used:
• Special additives
• Marine diesel fuel
• Heating oil
• FAME 16
and vegetable oil.
These fuels do not fulfil the requirements in accordance with Volvo recommendations andgenerate increased wear and engine damagethat is not covered by the Volvo warranty.

Empty tank and diesel engine
Once the engine has stopped due to fuel starva- tion, the fuel system needs a few moments tocarry out a check.
Before starting the engine after the fuel tank has
been filled with diesel - proceed as follows:
1. The remote control key must be inside the car.
2. Set the car in ignition position II - turn the
ignition dial to START without depressing
the brake pedal and hold the knob in the START position for approx. 4 seconds. Then
release the knob, which automatically returns to its starting position.
3. Wait approx. one minute.
4. To start the engine: Depress the brake pedal and turn the ignition dial to START again.
NOTE
Before filling with fuel in the event of fuel shortage:
• Stop the car on as flat/level ground aspossible - if the car is tilting there is a riskof air pockets in the fuel supply.

Diesel particulate filter Diesel-driven cars are equipped with a particu- late filter, which results in more efficient emis-sion control.
The particles in the exhaust gases are collected in the filter during normal driving. So-called"regeneration" is started in order to burn awaythe particles and empty the filter. This requiresthe engine to have reached normal operatingtemperature. Regeneration of the particulate filter is automatic and normally takes 10-20 minutes. It may take alittle longer at a low average speed. Fuel con-sumption may increase slightly during regenera-tion.
Regeneration in cold weatherIf the car is frequently driven short distances incold weather then the engine does not reachnormal operating temperature. This means thatregeneration of the diesel particulate filter doesnot take place and the filter is not emptied. When the filter has become approx. 80% full of particles, a yellow warning triangle illuminates, and the message
Particulate filter full See
Owner's manual is shown in the driver display.
Start regeneration of the filter by driving the car until the engine reaches normal operating tem-perature, preferably on a main road or motorway. The car should then be driven for approximately20 minutes more.
NOTE
The following may arise during regeneration:
• a smaller reduction of engine power may be noticed temporarily
• fuel consumption may increase temporar-ily
• a smell of burning may arise.
When regeneration is complete the warning text is cleared automatically. Use the parking heater
* in cold weather - the
engine then reaches normal operating tempera- ture more quickly.
IMPORTANT
If the filter is completely filled with particles, it may be difficult to start the engine and the fil-ter is non-functional. Then there is a risk thatthe filter will need to be replaced.

Economical driving
Drive economically and eco-consciously by driv- ing smoothly, thinking ahead, and adjusting yourdriving style and speed to the prevailing condi-tions.
• For lower fuel consumption, activate ECO drive mode.
• Use the Eco Coast 17
freewheel function -
engine braking will cease and the car'skinetic energy can be used to freewheel forlonger distances.
• Drive in the highest gear 18
possible, adapted
to the current traffic situation and road -lower engine speeds result in lower fuel con-sumption. Use the gear shift indicator.
• Drive at a steady speed and keep a good dis-tance to other vehicles and objects to mini-mise braking.
• High speed results in increased fuel con-sumption - the wind resistance increaseswith speed.
• Do not run the engine to operating tempera-ture at idling speed, but rather drive with anormal load right after starting - a coldengine consumes more fuel than a warmone. •
Drive with the correct air pressure in thetyres and check this regularly - select ECOtyre pressure for best results.
• Choice of tyres can affect fuel consumption -seek advice on suitable tyres from a dealer.
• Remove unnecessary items from the car -the greater the load the higher the consump-tion.
• Use engine braking to slow down, when itcan take place without risk to other roadusers.
• A roof load and space box increase windresistance, leading to higher consumption -remove the load carriers when not in use.
• Avoid driving with open windows.
WARNING
Never switch off the engine while moving, such as downhill, this deactivates importantsystems such as the power steering andbrake servo.

Towing bracket
*
The car can be equipped with a towing bracket that makes it possible to tow e.g. a trailer afterthe car.
There may be different towing bracket variants available for the car; contact a Volvo dealer formore information. For information on towing capacity and towball load, see the section "Towing capacity and tow-ball load".
IMPORTANT
When the engine is switched off, the constant battery voltage to the trailer connector can beswitched off automatically so as not to drainthe starter battery.
IMPORTANT
The towball needs regular cleaning and lubri- cation with grease in order to prevent wear.
17 See the section "Drive mode ECO".
18 Applies to driving with manual gear changing.

STARTING AND DRIVING
426
Driving with a trailer
When driving with a trailer, there are a number of points that are important to think about regar-ding the towing bracket, the trailer and how theload is positioned in the trailer.
Payload depends on the car's kerb weight. The total of the weight of the passengers and allaccessories, e.g. towbar, reduces the car's pay-load by a corresponding weight. The car is supplied with the necessary equipment for towing a trailer.
• The car's towing bracket must be of anapproved type.
• Distribute the load on the trailer so that theweight on the towing bracket complies withthe specified maximum towball load. Towballload is calculated as part of the car's payload.
• Increase the tyre pressure to the recom-mended pressure for a full load. For moreinformation on tyre pressure, see the section"Approved tyre pressures".
• The engine is loaded more heavily than usualwhen driving with a trailer.
• Do not tow a heavy trailer when the car isbrand new. Wait until it has been driven atleast 1000 km.
• The brakes are loaded much more than usualon long and steep downhill slopes. Downshiftto a lower gear and adjust your speed. •
Follow the regulations in force for the permit-ted speeds and weights.
• Maintain a low speed when driving with atrailer up long, steep ascents.
• The maximum trailer weights given only applyto altitudes up to 1000 metres above sealevel. At higher altitudes, engine power andthus the car's climbing ability is decreaseddue to the reduced air density, and the maxi-mum trailer weight must therefore bereduced. The weight of the car and trailermust be decreased by 10 % for each addi-tional 1000 m (or part thereof).
• Avoid driving with a trailer on inclines of morethan 12%.
NOTE
Extreme weather conditions, driving with a trailer or driving at high altitudes in combina-tion with fuel quality are factors that consider-ably increase the car's fuel consumption.
Trailer connectorAn adapter is required if the car's towing bracket has a 13 pin connector and the trailer has a 7 pinconnector. Use an adapter approved by Volvo.Make sure the cable does not drag on theground.
IMPORTANT
When the engine is switched off, the constant battery voltage to the trailer connector can beswitched off automatically so as not to drainthe starter battery.
Trailer weightsInformation about Volvo's permitted trailer weights is available in the article "Towingcapacity and towball load".
WARNING
Follow the stated recommendations for trailer weights. Otherwise, the car and trailer may bedifficult to control in the event of suddenmovement and braking.
NOTE
The stated maximum permitted trailer weights are those permitted by Volvo. National vehicleregulations can further limit trailer weightsand speeds. Towbars can be certified forhigher towing weights than the car canactually tow.
Direction indicators and brake lights on the trailer
If one or more of the trailer's direction indicators or brake light bulbs is broken, the driver display
