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 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

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.

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.

WHEELS AND TYRES
482
TyresAmongst other things, the function of the tyres is to carry load, provide grip on the road surface,dampen vibration and protect the wheel fromwear.
The tyres greatly affect the car's driving characte- ristics. The type of tyre, dimensions, tyre pressureand speed rating are important for how the carperforms.
Recommended tyresOn delivery, the car is equipped with Volvo origi- nal tyres that have the VOL 1
marking on the side
of the tyres. These tyres are carefully adapted to the car. In the event of changing tyres, it is there-fore important that the new tyres also have thismarking in order for the car's driving characteris-tics, comfort and fuel consumption to be main-tained.
New tyres
Tyres are perishable. After a few years they begin to harden at the same time as the frictioncapacity/characteristics gradually deteriorate. Forthis reason, aim to get as fresh tyres as possiblewhen you replace them. This is especially impor-tant with regard to winter tyres. The last four dig-its in the sequence mean the week and year ofmanufacture. This is the tyre's DOT marking(Department of Transportation), and this is statedwith four digits, for example 0715. The tyre in thefigure was manufactured in week 07 of 2015.
Tyre ageAll tyres older than 6 years old should bechecked by an expert even if they seem undam-aged. Tyres age and decompose, even if they arehardly ever or never used. The function cantherefore be affected. This applies to all tyres that are stored for future use. Examples of externalsigns which indicate that the tyre is unsuitable foruse are cracks or discoloration.
Wear and maintenanceCorrect tyre pressure results in more even wear.Driving style, tyre pressure, climate and road con-dition affect how quickly the tyres age and wear. To avoid differences in tread depth and to pre- vent wear patterns forming on the tyres, the frontand rear wheels can be switched with each other.A suitable distance for the first change is approx.5000 km and then at 10000 km intervals. Volvo recommends the an authorised Volvo work- shop is contacted for checking if you are uncer-tain about tread depth. If significant differences inwear (> 1 mm difference in tread depth) betweentyres have already occurred, then the least worntyres must always be fitted on the rear. Under-steer is normally easier to correct than oversteer,and leads to the car continuing forwards in astraight line rather than having the rear end skid-ding to one side, resulting in possible completeloss of control over the car. This is why it isimportant for the rear wheels never to lose gripbefore the front wheels.
WARNING
A damaged tyre may lead to loss of control over the car.

There may be deviations for certain tyre dimensions.
