Volvo V70 (2016 year). Instruction - part 18

Fuel - handling

Fuel of a lower quality than that recom-

mended by Volvo must not be used as engine

power and fuel consumption is negatively

affected.

WARNING

Always avoid inhaling fuel vapour and get-

ting fuel splashes in the eyes.
In the event of fuel in the eyes, remove any

contact lenses and rinse the eyes in plenty

of water for at least 15 minutes and seek

medical attention.
Never swallow fuel. Fuels such as petrol,

bioethanol and mixtures of them and die-

sel are highly toxic and could cause per-

manent injury or be fatal if swallowed.

Seek medical attention immediately if fuel

has been swallowed.

WARNING

Fuel which spills onto the ground can be

ignited.
Switch off the fuel-driven heater before

starting to refuel.
Never carry an activated mobile phone

when refuelling. The ring signal could

cause spark build-up and ignite petrol

fumes, leading to fire and injury.

Mixtures of various fuel types or use of

fuels which are not recommended will

invalidate Volvo's guarantees and any sup-

plementary service agreements; this is

applicable to all engines.

Economical driving (p. 308)

Extreme weather conditions, driving with a

trailer or driving at high altitudes in combi-

nation with fuel grade are factors that

could affect the car's performance.

Fuel - petrol

Petrol is used as fuel.

Only use petrol from well-known producers.

Never use fuel of dubious quality. Petrol must

fulfil the EN 228 standard if this is available.

•

95 RON can be used for normal driving.

•

98 RON is recommended for optimum

performance and minimum fuel consump-

tion.

When driving in temperatures above +38 °C,

fuel with the highest possible octane rating is

recommended for optimum performance and

fuel economy.

•

Use only unleaded petrol to avoid

damaging the catalytic converter.

•

Fuel containing metallic additives must

not be used.

•

Do not use any additives which have

not been recommended by Volvo.

Alcohols-ethanol

•

Fuel that contains up to

10 percent by volume ethanol is per-

mitted.

•

EN 228 E10 petrol (max

10 percent by volume ethanol) is

approved for use.

•

Ethanol higher than E10 (max

10 percent by volume ethanol) is not

permitted. T.ex. E85 is not permitted.

Fuel - diesel

Diesel is used as fuel.

Only use diesel fuel from well-known produc-

ers. Never use fuel of dubious quality. Diesel

fuel must fulfil the EN 590 and/or SS 155435

standards. Diesel engines are sensitive to

contaminants in the fuel, such as metals and

a high volume of sulphur for example.
At low temperatures (-6 °C to -40 °C), a par-

affin precipitate may form in the diesel fuel,

which may lead to ignition problems. Special

diesel fuel designed for low temperatures

around freezing point is available from the

major oil companies. This fuel is less viscous

at low temperatures and reduces the risk of

paraffin precipitate.
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 the

paintwork. Wash off any spillage with deter-

gent and water.

08 Starting and driving

305

Diesel fuel must:

•

fulfil the EN 590 and/or SS 155435

standards

•

have a sulphur content not exceeding

10 mg/kg

•

have a maximum of 7 vol % FAME

(Fatty Acid Methyl Ester).

tion. For more information, see Key posi-

Diesel type fuels that must not be used:

•

Special additives

•

Marine diesel fuel

•

Heating oil

•

FAME

(Fatty Acid Methyl Ester) and

vegetable oil.

These fuels do not fulfil the requirements in

accordance with Volvo recommendations

and generate increased wear and engine

damage that is not covered by the Volvo

warranty.

Empty tank
The design of the fuel system in a diesel

engine means that if the vehicle runs out of

fuel, the tank may need to be vented in the

workshop in order to restart the engine after

fuelling.

Once the engine has stopped due to fuel

starvation, the fuel system needs a few

moments to carry out a check. Do this before

starting the engine, once the fuel tank has

been filled with diesel:
1. Insert the remote control key in the igni-

tion switch and push it in to the end posi-

tions (p. 80).

2. Press the START button without

depressing the brake and/or clutch pedal.

3. Wait approx. one minute.
4. To start the engine: Depress the brake

and/or clutch pedal and then press the

START button again.

see Volvo service programme (p. 355).

Before filling with fuel in the event of fuel

shortage:

•

Stop the car on as flat/level ground as

possible - if the car is tilting there is a

risk of air pockets in the fuel supply.

Draining condensation from the fuel
filter
The fuel filter separates condensation from

the fuel. Condensation can disrupt engine

operation.

The fuel filter must be drained at the intervals

specified in the Service and Warranty Booklet

or if you suspect that the car has been filled

with contaminated fuel. For more information,

Certain special additives remove the water

separation in the fuel filter.

Option/accessory, for more information, see Introduction.

Diesel particle filter (DPF)

Diesel cars are equipped with a particle filter,

which results in more efficient emission con-

trol.

The particles in the exhaust gases are collec-

ted in the filter during normal driving. So-

called "regeneration" is started in order to

burn away the particles and empty the filter.

This requires the engine to have reached nor-

mal operating temperature.
Regeneration of the particle filter is automatic

and normally takes 10-20 minutes. It may

take a little longer at a low average speed.

Fuel consumption may increase slightly dur-

ing regeneration.

Regeneration in cold weather
If the car is frequently driven short distances

in cold weather then the engine does not

reach normal operating temperature. This

means that regeneration of the diesel particle

filter does not take place and the filter is not

emptied.
When the filter has become approx. 80% full

of particles, a yellow warning triangle is

shown in the combined instrument panel, and

the message

Soot filter full See manual

shown in its information display.
Start regeneration of the filter by driving the

car until the engine reaches normal operating

temperature, preferably on a main road or

motorway. The car should then be driven for

approximately 20 minutes more.

The following may arise during regenera-

tion:

•

a smaller reduction of engine power

may be noticed temporarily

•

fuel consumption may increase tem-

porarily

•

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 tem-

perature more quickly.

If the filter is completely filled with parti-

cles, it may be difficult to start the engine

and the filter is non-functional. Then there

is a risk that the filter will need to be

replaced.

Bi-Fuel* - introduction to vehicle gas

Filling vehicle gas*

Points to remember when filling vehicle gas

(CNG - Compressed Natural Gas) for cars

with the Bi-Fuel engine alternative.

Filling
Vehicle gas is filled via the gas nipple that is

located next to the fuel cap inside the fuel

filler flap.

1. Open the fuel filler flap and remove the

nipple's protective cover.

2. Push the nozzle towards the nipple and

make sure that the hose nozzle is

attached by turning the handle on the

nozzle to the left.

3. Then hold the start button on the gas

pump depressed for approx. 5 seconds.
> The tank is filled in a couple of

minutes.

4. Remove the nozzle by turning its handle

to the right.

08 Starting and driving

Option/accessory, for more information, see Introduction.

Switch for gas operation*

For cars with the Bi-Fuel engine alternative

there is a switch to change between gas

operation (CNG - Compressed Natural Gas)

and petrol operation. This is located by the

centre console.

Operation

Press the switch to change between gas

operation and petrol operation.
When the switchover takes place a clicking

noise can be heard in the cargo area. This is

normal - the noise is created when the tank

valves open.
The switch has two positions:

•

BI-FUEL illuminates in green - the car is

being driven on vehicle gas

•

BI-FUEL illuminates in orange - the car is

being driven on petrol (fuel gauge for

vehicle gas is extinguished).

The car always starts with petrol even if gas

operation is selected. When the engine has

started the system automatically changes to

gas operation - normally within a few seconds

of a warm start.
When starting with a cold engine it will take

longer before the car changes to gas opera-

tion in order to ensure the lowest possible

emissions.

warning lamp
If the warning lamp in the switch illuminates,

and/or repetitive acoustic signals can be

heard, then the car needs servicing. Acknowl-

edge the warning by pressing the switch and

visit the nearest workshop - an authorised

Volvo workshop is recommended.

Catalytic converters

The purpose of the catalytic converters is to

purify exhaust gases. They are located close

to the engine so that operating temperature is

reached quickly.

The catalytic converters consist of a monolith

(ceramic or metal) with channels. The channel

walls are lined with a thin layer of platinum/

rhodium/palladium. These metals act as cata-

lysts, i.e. they participate in and accelerate a

chemical reaction without being used up

themselves.

Lambda-sond

oxygen sensor

The Lambda-sond is part of a control system

intended to reduce emissions and improve

fuel economy. For more information, see Fuel

consumption and CO2 emissions (p. 425).
An oxygen sensor monitors the oxygen con-

tent of the exhaust gases leaving the engine.

This value is fed into an electronic system

that continuously controls the injectors. The

ratio of fuel to air directed to the engine is

continuously adjusted. These adjustments

create optimal conditions for efficient com-

bustion, and together with the three-way cat-

alytic converter reduce harmful emissions

(hydrocarbons, carbon monoxide and nitrous

oxides).

•

For lowest fuel consumption, activate
ECO* (p. 290)

•

Use the ECO Guide which indicates how

fuel-efficiently the car is being driven, see

Eco guide & Power guide* (p. 69).

•

Drive in the highest gear possible, adap-

ted to the current traffic situation and

road - lower engine speeds result in lower

fuel consumption. Use the gear indicator

(p. 272).

•

Avoid sudden unnecessary acceleration

and heavy braking.

•

High speed results in increased fuel con-

sumption - the wind resistance increases

with speed.

•

Do not run the engine to operating tem-

perature at idling speed, but rather drive

with a light load as soon as possible - a

cold engine consumes more fuel than a

warm one.

•

Drive with the correct air pressure in the

tyres and check this regularly - select

ECO tyre pressure for best results, see

Tyres - approved tyre pressures (p. 430).

•

Choice of tyres can affect fuel consump-

tion - seek advice on suitable tyres from a

dealer.

•

Remove unnecessary items from the car -

the greater the load the higher the con-

sumption.

•

Use engine braking to slow down, when it

can take place without risk to other road

users.

•

A roof load and ski box increase air resis-

tance, leading to higher consumption -

remove the load carriers when not in use.

•

Avoid driving with open windows.

tion's environmental philosophy, see Environ-

mental philosophy (p. 22).

WARNING

Never switch off the engine while moving,

such as downhill, this deactivates impor-

tant systems such as the power steering

Driving with a trailer*

When driving with a trailer there are a number

of important points to think about regarding

e.g. the towing bracket, the trailer and how

the load is positioned in the trailer.

Payload depends on the car's kerb weight.

The total of the weight of the passengers and

all accessories, e.g. towbar, reduces the car's

payload by a corresponding weight. For more

detailed information, see Weights (p. 410).
If the towing bracket is mounted by Volvo,

then the car is delivered with the necessary

equipment for driving with a trailer.

•

The car's towing bracket must be of an

approved type.

•

If the towbar is retrofitted, check with

your Volvo dealer that the car is fully

equipped for driving with a trailer.

•

Distribute the load on the trailer so that

the weight on the towing bracket com-

plies with the specified maximum towball

load.

•

Increase the tyre pressure to the recom-

mended pressure for a full load. For infor-

approved tyre pressures (p. 430).

•

The engine is loaded more heavily than

usual when driving with a trailer.

Only applies to cars with automatic gearbox.

08 Starting and driving

310

Option/accessory, for more information, see Introduction.

•

Do not tow a heavy trailer when the car is

brand new. Wait until it has been driven

at least 1000 km.

•

The brakes are loaded much more than

usual on long and steep downhill slopes.

Downshift to a lower gear and adjust your

speed.

•

For safety reasons, the maximum permit-

ted speed for the car when coupled with

a trailer should not be exceeded. Follow

the regulations in force for the permitted

speeds and weights.

•

Maintain a low speed when driving with a

trailer up long, steep ascents.

•

Avoid driving with a trailer on inclines of

more than 12%.

Trailer cable
An adapter is required if the car's towing

bracket has 13 pin electrics and the trailer

has 7 pin electrics. Use an adapter cable

approved by Volvo. Make sure the cable does

not drag on the ground.

Direction indicators and brake lights on
the trailer
If any of the trailer's lamps for direction indi-

cators are broken, then the combined instru-

ment panel's symbol for direction indicators

flashes faster than normal and the information

display shows the text

Trailer indicator

malfunction

If any of the trailer's lamps for the brake light

are broken then the

Trailer brake light

malfunction

text is shown.

Level control*
The rear shock absorbers maintain a constant

height irrespective of the car's load (up to the

maximum permissible weight). When the car

is stationary the rear of the car lowers slightly,

which is normal

Trailer weights
For information on Volvo's permitted trailer

weights, see Towing capacity and towball

load (p. 411).

Driving with a trailer* - manual gearbox

The stated maximum permitted trailer

weights are those permitted by Volvo.

National vehicle regulations can further

limit trailer weights and speeds. Towbars

may be certified for higher or lower towing

weights than the car can actually tow.

WARNING

Follow the stated recommendations for

trailer weights. Otherwise, the car and

trailer may be difficult to control in the

event of sudden movement and braking.

Recovery (p. 318)

Towing eye

The towing eye is screwed into a threaded

socket behind a cover on the right-hand side

of the bumper, front or rear.

Attaching the towing eye

Take out the towing eye that is located

under the floor hatch in the cargo area.
Applies to Bi-Fuel* cars: the towing eye is

stored together with the tools in the stor-

age compartment in the front part of the

cargo area.

08 Starting and driving

318

The cover for the towing eye's attach-

ment point is available in two variants

which must be opened in different ways:

•

Open the variant with a recess using a

coin or similar inserted in the recess,

turning it outwards. Then turn out the

cover completely and remove it.

•

The second variant has a marking

along one side or in a corner: Press the

marking with a finger and fold out the

opposite side/corner at the same time

using a coin or similar - the cover turns

around its axis and can then be

removed.

Screw the towing eye right in up to its

flange. Turn in the towing eye firmly e.g.

using the wheel wrench.
After use, unscrew the towing eye and

return it to its place.
Finish by refitting the cover onto the

bumper.

The towing eye may be used to pull the car

up onto a recovery vehicle with a flatbed plat-

form. The car's position and ground clear-

ance determine whether it is possible. If the

slope of the recovery vehicle's ramp is too

steep, or if the ground clearance under the

car is inadequate, then the car may be dam-

aged if you try to pull it up using the towing

eye. Raise the car using the recovery vehi-

cle's lifting device if necessary.

WARNING

No one/nothing is allowed to remain

behind the recovery vehicle while the car

pulled up onto the flatbed platform.

The towing eye is only designed for towing

on roads - not for pulling the car unstuck

or out of a ditch. Call a recovery service for

recovery assistance.
