No or poor connection

Factors affecting the network.

The amount of data transferred is dependent on
the services or apps in use in the car. For exam-
ple, streaming audio can require large amounts of
data which requires a good connection and good
signal strength.

Mobile phone to car

The speed of the connection may vary depending
on the location of the mobile phone in the car.
Move the mobile phone handset closer to the
centre display in order to increase the signal
strength. Ensure that there is no source of inter-
ference in between.

Mobile phone to network

The speed of the mobile network varies depend-
ing on the coverage in the present location. Poor
network coverage may occur, for example in tun-
nels, in mountainous country, in deep valleys or
indoors. The speed also depends on the agree-
ment you have with your network.

In the event of problems with data traffic, con-
tact your network operator.

Restarting the phone

If there are problems with the connection then it
may help to restart the phone.

WHEELS AND TYRES

528

Tyres

Amongst other things, the function of the tyres is
to carry load, provide grip on the road surface,
dampen vibration and protect the wheel from
wear.

The tyres greatly affect the car's driving characte-
ristics. The type of tyre, dimensions, tyre pressure
and speed rating are important for how the car
performs.

Recommended tyres

On delivery, the car is equipped with Volvo origi-
nal tyres that have the VOL

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 this
marking 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 friction
capacity/characteristics gradually deteriorate. For
this reason, aim to get as fresh tyres as possible
when 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 of
manufacture. This is the tyre's DOT marking
(Department of Transportation), and this is stated
with four digits, for example 0717. The tyre in the
figure was manufactured in week 07 of 2017.

Tyre age

All tyres older than 6 years old should be
checked by an expert even if they seem undam-
aged. Tyres age and decompose, even if they are
hardly ever or never used. The function can
therefore be affected. This applies to all tyres that

are stored for future use. Examples of external
signs which indicate that the tyre is unsuitable for
use are cracks or discoloration.

Wear and maintenance

Correct 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 front
and 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 in
wear (> 1 mm difference in tread depth) between
tyres have already occurred, then the least worn
tyres must always be fitted on the rear. Under-
steer is normally easier to correct than oversteer,
and leads to the car continuing forwards in a
straight line rather than having the rear end skid-
ding to one side, resulting in possible complete
loss of control over the car. This is why it is
important for the rear wheels never to lose grip
before the front wheels.

WARNING

A damaged tyre may lead to loss of control

over the car.

There may be deviations for certain tyre dimensions.

Tyres' rotation direction

Tyres with a tread pattern which are designed to
only turn in one direction have the direction of
rotation marked with an arrow.

The arrow shows the tyre's direction of rotation.

The tyre must always rotate in the same direction
throughout its lifespan. Tyres should only be
switched between front and rear positions, never
between left and right-hand sides, or vice versa. If
the tyres are fitted incorrectly, the car's braking
characteristics and capacity to force rain and
slush out of the way are adversely affected. Tyres
with the greatest tread depth should always be
fitted to the rear of the car (to decrease the risk
of skidding).

Make sure that both pairs of wheels have the
same type and dimension, and also the same
make.

Tread wear indicators on the tyres

Tread wear indicators show the status of the
tyre's tread depth.

A tread wear indicator is a narrow elevation
across the longitudinal grooves of the tyre's tread
pattern. On the side of the tyre are the letters
TWI (Tread Wear Indicator). When the tyre's tread
depth is down to 1.6 mm (1/16"), the tread will
be level in height with the tread wear indicators.
Change to new tyres as soon as possible.
Remember that tyres with little tread depth pro-
vide very poor grip in rain and snow.

Checking the tyre pressures

Tyres with the correct air pressure increase driv-
ing safety, save fuel and extend the service life of
the tyres.

Tyre pressure decreases over time, this is a natu-
ral phenomenon. Tyre pressure also varies
depending on ambient temperature. Inadequate
tyre pressure increases fuel consumption, short-
ens tyre lifespan and impairs the car's driving
characteristics. Driving on tyres with tyre pressure
that is too low could result in the tyres overheat-
ing and being damaged. Tyre pressure affects
travelling comfort, road noise and driving charac-
teristics.

Recommended tyre pressure

The tyre pressure label on the driver's side door
pillar (between frame and rear door) shows which

pressures the tyres should have at different loads
and speed conditions.

Improved fuel economy with ECO pressure

For a light load (max. 3 people) and a speed of
up to 160 km/h (100 mph), the ECO pressures
can be chosen for optimum fuel economy. How-
ever, the lower comfort pressures are recom-
mended instead if optimum noise and travelling
comfort are desired.

Checking the air pressure

1. Check the tyre pressures monthly. Carry out

the check on cold tyres, which means that
the tyres should have the same temperature
as the outside temperature. After several few
kilometres of driving, the tyres warm up and
the pressure increases.

2. If necessary, inflate so that the air pressure

corresponds with the approved tyre pressure
in accordance with the tyre pressure label.

•

After a tyre has been inflated, always refit
the dust cap in order to avoid damage to
the valve from gravel, dirt, etc.

•

Only use plastic dust caps. Metal dust
caps can rust and become difficult to
unscrew.

Tyre monitoring

The tyre monitoring system, Indirect Tyre
Pressure Monitoring System (ITPMS), gives a
warning with an indicator symbol in the driver
display when the pressure in one or more of the
car's tyres is too low.

If the symbol first flashes for approximately one
minute and then changes to a constant glow, it
may indicate that the system cannot detect or
warn of low tyre pressure as intended.

mately one minute and then
changes over to illuminating
with a constant glow in the
event of a fault in the ITPMS
system.

System description

ITPMS measures differences in rotation speed
between the different wheels via the ABS system
in order to be able to determine whether they
have the correct tyre pressure. If the tyre pres-
sure is too low, the tyre's diameter is changed
and, as a result, so is its rotation speed. By com-
paring the tyres with each other the system can
determine whether one or more tyres have pres-
sure that is too low.

When the tyre pressure is too low, the indicator
symbol for low tyre pressure is illuminated in the
display and a message is shown, see also the
heading "Message in the driver display" below.

General information on the tyre monitoring
system

In the information below, the tyre monitoring sys-
tem is referred to generically as TPMS.

Each tyre, including the spare tyre

*, should be

checked once a month. When checking, the tyre
should be cold and have the air pressure recom-
mended by the car manufacturer specified on the
tyre pressure label or in the tyre pressure table. If
the car has tyres of a different size than that rec-
ommended by the manufacturer, find out what
the correct air pressure level is for these.

As an extra safety feature, the car is equipped
with a tyre pressure monitoring system (TPMS),
which shows when the air pressure in one or
more tyres is too low. When the indicator symbol
for low air pressure is lit, stop and check the tyres
as soon as possible and inflate to the correct air
pressure.

Driving with tyres that have tyre pressure that is
too low may cause the tyre to overheat, which
can cause a puncture. Low tyre pressure also
reduces fuel efficiency as well as tyre service life,
and can affect car handling and stopping ability.
Note that TPMS does not replace regular tyre
maintenance. It is the driver's responsibility to
maintain correct tyre pressure, even if the limit for
low tyre pressure has not been reached so that
the indicator symbol illuminates.

The car is also equipped with a TPMS system
fault indicator, which indicates when the system

is not functioning correctly. The TPMS system
fault indicator is combined with the indicator sym-
bol for low tyre pressure. When the system
detects a fault, the symbol in the driver display
will flash for about one minute and then remain
illuminated. This procedure will be repeated when
the car is started until the fault has been rectified.
When the symbol is illuminated, the system's abil-
ity to detect or warn of low tyre pressure may be
affected.

A TPMS system fault can occur for several rea-
sons, such as after changing to a spare tyre, or
changing tyres or wheels that prevent TPMS from
functioning correctly.

Always check the indicator symbol for TPMS
after changing one or more tyres in order to
ensure the new tyre or wheel is working correctly
with TPMS.

Messages in the driver display

The following messages may be shown when the
indicator symbol is illuminated:

•

Tyre pressure low

Check tyres, calibrate

after fill

•

Tyre pressure system

Temporarily

unavailable

•

Tyre pressure system

Service required

If the system cannot determine which tyre has
low pressure, all four tyres will be indicated in the
centre display.

To bear in mind

•

Always calibrate the system after a wheel
change or tyre pressure adjustment. See the
tyre pressure label on the driver's side door
pillar for Volvo's recommended tyre pres-
sures.

•

The system does not replace normal tyre
maintenance.

•

There is no option to deactivate ITPMS.
