Hold and Charge function

In some situations, it can be useful to be able
to control the hybrid battery's state of charge
while driving is in progress. This is possible
with the functions 

Hold

 and 

Charge

.

Hold

 and 

Charge

 are available in all drive

modes. The functions are cancelled if 

Pure

drive mode is activated.

Function buttons for Hold and Charge

The functions are activated in the centre dis-
play's function view.

Hold

Battery level sustained for
later use

.

The function maintains the
charge in the hybrid battery
for electric drive and saves
available electricity for later

use, e.g. for driving in an urban environment or
through a residential area.

The car works as for normal hybrid operation
with discharged battery where, in addition to
re-using brake-generated energy, for example,
the car starts the internal combustion engine
more often in order to maintain the charge in
the battery.

Preparations for a long trip

Before a driving holiday or some other type of
long journey, it is important to check the car's
functions and equipment particularly care-
fully.

Check that

•

the engine is working normally and that
fuel consumption is normal

•

there are no leaks (fuel, oil or other fluid)

•

braking effect on braking works as
intended

•

all lamps are working - adjust headlamp
level if the car is heavily laden

•

the tyres have sufficient tread depth and
pressure. Change to winter tyres when
driving to areas where there is a risk of
snowy or icy road surfaces

•

starter battery charging is good

•

the wiper blades are in good condition

•

a warning triangle and high-visibility vest
are located in the car - legally required in
certain countries

Winter driving

For winter driving it is important to perform
certain checks of the car in order to ensure
that it can be driven safely.

Check the following in particular before the
cold season:

•

The engine coolant must contain 50%
glycol. This mixture protects the engine
against frost down to approx. -35°C
(-31°F). To avoid health risks, different
types of glycol must not be mixed.

•

The fuel tank must be kept filled to pre-
vent condensation.

•

Engine oil viscosity is important. Oils with
lower viscosity (thinner oils) facilitate star-
ting in cold weather and also reduce fuel
consumption while the engine is cold.

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. Cold
weather places great demands on the
starter battery and its capacity is reduced
by the cold.

•

Use washer fluid with antifreeze to avoid
ice forming in the washer fluid reservoir.

Slippery driving conditions

To achieve optimum roadholding Volvo recom-
mends using winter tyres on all wheels if there
is a risk of snow or ice.

NOTE

The use of winter tyres is a legal require-
ment in certain countries. Studded tyres
are not permitted in all countries.

Practise driving on slippery surfaces under
controlled conditions to learn how the car
reacts.

Driving in water

Wading means the car being driven through
water, e.g. on a flooded road. Driving in water
must be performed with great caution.

Observe the following to prevent damage to
the car when driving through water:

•

The water level must not be higher than
the floor of the car. If possible, check the
depth at the deepest point before starting
to drive through the water. Extra caution
should be exercised when passing
through flowing water.

•

Always change to 

Off Road

 drive mode

before driving through water in order to
ensure that the internal combustion
engine is running.

•

Do not drive faster than walking pace.

•

Do not stop the car in the water. Drive for-
ward carefully or reverse the car back out
of the water.

•

Remember that waves created by oncom-
ing traffic may rise above the level for the
floor of the car.

•

Avoid driving through salt water (corrosion
risk).

IMPORTANT

Parts of the car (e.g. engine, gearbox,
driveline or electrical components) may be
damaged when driving through water with
a level higher than the floor of the car.
Damaged caused to a component caused
by submersion, hydrolock or lack of oil is
not covered by the warranty.

In the event of stalling in water, do not try
to restart. Instead, tow the car out of the
water and transported on a low loader to a
workshop. An authorised Volvo workshop
is recommended.

When the water has been passed, depress the
brake pedal lightly and check that full brake
function is achieved. Water and mud for
example can make the brake linings wet
resulting in delayed brake function.

If necessary, clean the contact for the trailer
coupling after driving in water and mud.

Handling of fuel

Do not use fuel with a lower quality than that
recommended by Volvo, as this will nega-
tively affect engine power and fuel consump-
tion.

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 diesel

are highly toxic and could cause permanent

injury or be fatal if swallowed. Seek medi-

cal 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.

IMPORTANT

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.

Petrol (p. 501)

STARTING AND DRIVING

501

Petrol

It is important to use the correct fuel during
refuelling. Petrol is available with different
octane ratings that are adapted for different
types of driving.

Only use petrol from well-known producers.
Never use fuel of dubious quality. The petrol
must fulfil the EN 228 standard.

Identifier for petrol

Decal on the inside of the fuel filler flap.

The identifier in accordance with the CEN
standard EN16942 is located on the inside of
the fuel filler flap, and will be on corresponding
fuel pumps and their nozzles at filling stations
throughout Europe by 12 October 2018 at the
latest.

These are the identifiers that apply for current
standard fuels in Europe. Petrol with the fol-
lowing identifiers may be used in cars with
petrol engine:

E5 is a petrol with maximum
2.7% oxygen and maximum
5 volume % ethanol.

E10 is a petrol with maximum
3.7% oxygen and maximum
10 volume % ethanol.

IMPORTANT

•

Fuel that contains up to 10 percent by
volume ethanol is permitted.

•

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, e.g. E85 is not permit-
ted.

Octane rating

•

RON 95 can be used for normal driving.

•

RON 98 is recommended for good power
and low fuel consumption.

•

An octane rating lower than RON 95 must
not be used.

When driving in temperatures above +38 °C
(100 °F), fuel with the highest octane rating is
recommended for adapted performance and
fuel economy.

IMPORTANT

•

Use only unleaded petrol to avoid dam-
aging the catalytic converter.

•

Fuel containing metallic additives must
not be used.

•

Do not use any additives which have
not been recommended by Volvo.

Petrol particle filter

16

Petrol cars are fitted with particle filters for
more efficient emission control.

Particles in the exhaust gases are collected in
the petrol particle filter during normal driving.
In normal driving conditions, passive regenera-
tion takes place, which leads to the particles
being oxidised and burned away. The filter is
emptied in this way.

If the car is driven at low speed or with repea-
ted cold starts in low outside temperature,
active regeneration may be necessary. Regen-
eration of the particulate filter is automatic and
normally takes 10-20 minutes. Fuel consump-
tion may temporarily increase during regenera-
tion.

Use the parking heater in cold weather - the
engine then reaches normal operating tem-
perature more quickly.

When driving short distances at low
speeds in a petrol car

The capacity of the emissions system is affec-
ted by how the car is driven. Driving varying
distances and at different speeds is important
in order to achieve performance that is as
energy-efficient as possible.

Driving short distances at low speeds (or in
cold climates) frequently, where the engine

does not reach normal operating temperature,
can lead to problems that can eventually
cause a malfunction and trigger a warning
message. If the vehicle is mostly driven in city
traffic, it is important to regularly drive at
higher speeds to allow the emissions system
to regenerate.

•

The car should be driven on A-roads at
speeds in excess of 70 km/h (44 mph) for
at least 20 minutes between each refuel-
ling.

Overheating in the engine and

drive system

Under certain conditions, e.g. hard driving in
hilly terrain and hot climate, there is a risk
that the engine and drive system may over-
heat – in particular with a heavy load.

•

In the event of overheating, the engine's
power may be limited temporarily.

•

Remove any auxiliary lamps from in front
of the grille when driving in hot climates.

•

If the temperature in the engine's cooling
system becomes too high then a warning
symbol is illuminated and the driver dis-
play shows the message

Overloading the starter battery

The electrical functions in the car load the
starter battery to varying degrees. Avoid
using the ignition 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 func-
tions which use 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, a message
is shown in the driver display. The energy-sav-
ing function then shuts down certain functions
or reduces certain functions such as the venti-
lation fan and/or audio system.

–

In which case, charge the starter battery
by starting the car and then running it for
at least 15 minutes - starter battery charg-
ing is more effective during driving than
running the engine at idling speed while
stationary.

Using jump starting with another

battery

If the starter battery is discharged then the
car can be started with current from another
battery.

Charging point for jump-starting own car.

IMPORTANT

The car’s charging point is only intended
for jump-starting the car itself. The charg-
ing point is not intended for jump-starting
another car. Using the charging point to
jump start another car may cause a fuse to
blow, which means the charging point will
stop working.

When a fuse has blown the message 

12 V

Battery

 

Fuse failure Service required

 is

shown in the driver display. Volvo recom-

mends that an authorised Volvo workshop is
contacted.

When jump-starting the car, the following
steps are recommended to avoid short circuits
or other damage:

1. Set the car's electrical system in ignition

position 

0

.

2. Check that the donor battery has a voltage

of 12 V.

3. If the donor battery is installed in another

car - switch off the donor car's engine and
make sure that the two cars do not touch
each other.

4. Connect one of the red jump lead's

clamps to the donor battery's positive ter-
minal (1).

IMPORTANT

Connect the start cable carefully to avoid
short circuits with other components in the
engine compartment.

5. Open the positive jump-starting point's

cover (2).

6. Connect the red jump lead's other clamp

onto the car's positive jump-starting point
(2).

7. Connect one of the black jump lead's

clamps to the donor battery's negative ter-
minal (3).

8. Connect the black jump lead's other

clamp onto the car's negative jump-star-
ting point (4).

9. Check that the jump lead clamps are

affixed securely so that there are no sparks
during the starting attempt.

10. Start the engine of the "donor car" and

allow it to run a few minutes at a speed
slightly higher than idle approx. 1500 rpm.

}}

* Option/accessory.

505

11. Start your own car's engine. If the start

attempt fails then extend the charging
time to 10 minutes, and then make a new
start attempt.

NOTE

When starting the engine in normal condi-
tions the car's electric drive motor is priori-
tised - the petrol engine remains switched
off. This means that after the start knob
has been turned clockwise, the electric
motor has "started" and the car is ready to
move. A started motor is indicated by the
driver display's indicator lamps extinguish-
ing and its preset theme illuminating.

IMPORTANT

Do not touch the connections between
cable and car during the starting attempt.
There is a risk of sparks forming.

12. Remove the jump leads in reverse order -

first the black and then the red.

Make sure that none of the black jump
lead's clamps comes into contact with the
car's positive jump-starting point/donor
battery's positive terminal or the clamp
connected to the red jump lead.

WARNING

•

The battery can generate oxyhydrogen
gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected incorrectly, and this can be
enough for the battery to explode.

•

Do not connect the jump leads to any
fuel system component or any moving
part. Be careful of hot engine parts.

•

The battery contains sulphuric acid,
which can cause serious burns.

•

If sulphuric acid comes into contact
with eyes, skin or clothing, flush with
large quantities of water. If acid
splashes into the eyes - seek medical
attention immediately.

•

Never smoke near the battery.

NOTE

The car cannot be started if the hybrid bat-
tery is discharged.

Towbar

*

The car can be equipped with a towbar that
makes it possible to tow e.g. a trailer behind
the car.

There may be different towbar variants availa-
ble for the car. Contact a Volvo dealer for more
information.

IMPORTANT

When the engine is switched off, the con-
stant battery voltage to the trailer connec-
tor can be switched off automatically so as
not to drain the starter battery.

IMPORTANT

The towball needs regular cleaning and
lubrication with grease in order to prevent
wear.

NOTE

When a hitch with a vibration damper is
used, the towball must not be lubricated.

This also applies when fitting a bicycle rack
that is clamped in around the towball.

NOTE

If the car is equipped with a towbar, there
is no rear mounting for a towing eye.

Driving with a trailer

When driving with a trailer, there are a num-
ber of points that are important to think about
regarding the towbar, 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.

The car is supplied with the necessary equip-
ment for towing a trailer.

•

The car's towbar must be of an approved
type.

•

Distribute the load on the trailer so that
the weight on the towbar complies with
the specified maximum towball load. Tow-
ball load is calculated as part of the car's
payload.

•

Increase the tyre pressure to the recom-
mended pressure for a full load.

•

The engine is loaded more heavily than
usual when driving with a trailer.

•

Do not tow a heavy trailer when the car is
brand new. Wait until it has been driven at
least 1000 km (620 miles).

•

The brakes are loaded much more than
usual on long and steep downhill slopes.
Downshift to a lower gear when shifting
manually and adjust your speed.

•

Follow the regulations in force for the per-
mitted speeds and weights.

•

Maintain a low speed when driving with a
trailer up long, steep ascents.

•

The maximum indicated trailer weight only
applies to heights up to 1000 metres
above sea level (3280 ft). At higher eleva-
tions, the engine output and the vehicle's
climbing ability are reduced due to the
reduced air density, and the maximum
trailer load must therefore be reduced. The
weight of the car and trailer must be
decreased by 10% for each additional
1000 m (3280 ft) or part thereof.

•

Avoid driving with a trailer on inclines of
more than 12%.

NOTE

To facilitate towing a trailer on a car with
air suspension

*

, select the 

Suspension

Control

Dynamic

 setting in Individual

drive mode.

NOTE

Extreme weather conditions, driving with a
trailer or driving at high altitudes, in combi-
nation with poorer fuel quality than recom-
mended, are factors that considerably
increase the car's fuel consumption.

Trailer connector

An adapter is required if the car's towbar has a
13 pin connector and the trailer has a 7 pin
connector. Use an adapter approved by Volvo.
Make sure the cable does not drag on the
ground.

IMPORTANT

When the engine is switched off, the con-
stant battery voltage to the trailer connec-
tor can be switched off automatically so as
not to drain the starter battery.

Trailer weights

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.

NOTE

The stated maximum permitted trailer
weights are those permitted by Volvo.
National vehicle regulations can further
limit trailer weights and speeds. Towbars
can be certified for higher towing weights
than the car can actually tow.
