Automatic deactivation
In gear position D the steering wheel paddles are
deactivated after a short time if they are not used. This is indicated by means of the figure for thecurrent gear extinguishing. The exception is during engine braking - then the paddles are activated for as long as engine brak-ing is in progress. In gear position M there is no automatic deactiva-
tion.

Start/Stop
With the Start/Stop function, the engine switches off temporarily when the car has stop-ped e.g. at traffic lights or in a traffic queue, andthen starts again automatically when the journeyis resumed.
Start/Stop is one of several energy-saving func- tions intended to reduce fuel consumption, whichin turn helps to reduce exhaust emissions. The system makes it possible to adopt an envi- ronmentally-conscious driving style by allowingthe car to engine auto-stop when possible.

Using the Start/Stop function The Start/Stop function temporarily switches off the engine when stationary and then restarts itautomatically when the journey is resumed.
The Start/Stop function is available when the engine is started and can be activated if certainconditions have been met. The driver display indi-cates whether the function is available, active orunavailable, see heading "Symbols in driver dis-play" below. All of the car's normal systems such as lighting, radio, etc. work normally, even when the engine isauto-stopped. However, some equipment mayhave its output temporarily reduced, e.g. the cli-mate control system's fan speed or extremelyhigh volume on the audio system.
Auto-stopThe following is required for the engine to auto-stop:

In the centre display's function view
A car without drive mode con- trol has a function button for
Driving mode ECO in the
centre display's function view.
–Press the button in order to activate the function.
> An indicator in the button illuminates when the function is activated.
Freewheel function Eco Coast 10The freewheel function Eco Coast means in prac- tice that engine braking ceases, meaning in turnthat the car's kinetic energy is used to freewheelfor longer distances. When the driver releasesthe accelerator pedal the gearbox is automaticallydisengaged from the engine whose speed isreduced to idling speed with reduced consump-tion. The function is best used where it is possible to freewheel a long way, e.g. roads with a slightdownhill gradient or when there is a predictablespeed reduction to freewheel into a zone with alower speed limit.
Activating the freewheel function
The function is activated when the accelerator pedal is fully released, in combination with thefollowing parameters:
• Drive mode
Eco is activated.
• The gear selector is in
D position.
• Speed within the range of approx. 65-140 km/h (40-87 mph).
• The road's downhill gradient is not steeperthan approx. 6%.
The driver display shows
COASTING when the
freewheel function is being used.
Limitations
The freewheel function is not available if:
• Engine and/or gearbox are not at normal operating temperature.
• The cruise control is activated.
• The gear selector is moved from the
D posi-
tion and the manual position.
• The speed is outside the range ofapprox. 65-140 km/h (40-87 mph).
• The road's downhill gradient is steeper thanapprox. 6%.
• Manual gear changing is performed with the steering wheel paddles
*.
Deactivating and switching off the freewheel function
In certain situations it may be desirable to deacti- vate or switch off the function in order to useengine braking. Examples of such situations maybe on steep downhill gradients or before animminent overtaking manoeuvre - in order to beable to do it in the safest way possible. Deactivate the freewheel function as follows:
• Actuate the accelerator or brake pedal.
• Move the gear selector to manual position.
• Changing gear with steering wheel paddles
*.
Switch off the freewheel function as follows:
• Change drive mode
*, or switch off the
Driving mode ECO in the function view.
Even without the freewheel function, it is possible to freewheel for short distances. This, in turn,reduces consumption. However, for the best fueleconomy it is better to have the freewheel func-tion activated and be able to freewheel for longerdistances.
ECO gauge in the driver displayThe ECO gauge indicates how fuel-efficient thedriving is:

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 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

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.

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 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.
