In order for the system for tyre pressure
monitoring

4

to work correctly, a reference

value for the tyre pressure must be saved.
This must take place every time the tyres are
changed or the tyre pressure is changed so
that the system can warn about low pressure
correctly.

For example, when driving with a heavy load
or at high speed above 160 km/h (100 mph),
the tyre pressure should be adjusted in
accordance with Volvo's recommended tyre
pressure values. The system is then reset by
saving a new tyre pressure.

Perform the following procedure to store a
new tyre pressure as a reference value in the
system:

1. Switch off the car.

2. Inflate the tyres to the correct pressure,

see the decal on the door pillar on the driv-
er's side showing the recommended pres-
sure for factory fitted tyres.

3. Start the car.

4. Open the

Car Status

app in the app view.

5. Press

TPMS

.

NOTE

The car must be stationary for the

Store

Pressure

button to be selectable.

6. Press

Store Pressure

.

7. Tap on

OK

to confirm that the tyre pres-

sure in all four tyres has been checked and
adjusted.

8. Drive the car until the new tyre pressure

has been saved. The new tyre pressure is
stored when the car is driven at a speed
above 35 km/h (22 mph).
> When sufficient data has been collec-

ted for the system to be able to detect
low tyre pressure, the animation show-
ing storage progress disappears from
the centre display. The system does not
provide additional confirmation that a
new tyre pressure has been saved.

If storing fails, a message is shown:

Storing

pressure unsuccessful. Try again.

If the car's ignition is switched off before the
new tyre pressure has been saved then the
procedure needs to be performed again. Allow
the storing to finish within the same driving
cycle to ensure that the new tyre pressure has
been saved correctly.

warns

that tyre pressure is too low, action is
required.

Check and rectify the tyre pressure
when the indicator symbol for the
system is illuminated and the

Tyre

pressure low

message is shown.

1. Switch off the car.

2. Check the tyre pressure in all four tyres

with a tyre pressure gauge.

3. Inflate the tyres to the correct pressure,

see the decal on the door pillar on the driv-
er's side showing the recommended pres-
sure for factory fitted tyres.

4. Always save a new tyre pressure in the

system via the centre display after the tyre
pressure has been adjusted.

Note that the indicator symbol does not
extinguish until the low tyre pressure has
been rectified and storing a new tyre pres-
sure has been started.

NOTE

To avoid incorrect tyre pressure, the pres-
sure should be checked on cold tyres.
"Cold tyres" means the tyres are the same
temperature as the ambient temperature
(approx. 3 hours after the car has been
driven). After a few kilometres of driving,
the tyres warm up and the pressure increa-
ses.

NOTE

•

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.

WARNING

•

Incorrect tyre pressure may lead to tyre
failure, which could result in the driver
losing control of the car.

•

The system cannot indicate sudden
tyre damage in advance.

Spare wheel

*

The spare wheel, the Temporary Spare type,
can be used to temporarily replace a punc-
tured normal wheel.

The spare tyre is only designed for temporary
use. Replace it with a normal wheel as soon as
possible.

The car's driving characteristics can be
changed when the spare wheel is used and
the ground clearance is reduced. Do not wash
the car in an automatic car wash if the
Temporary Spare is being used.

Recommended tyre pressure must be main-
tained regardless of the position of the tempo-
rary spare wheel on the car.

If the spare tyre is damaged then a new one
can be purchased from a Volvo dealer.

WARNING

•

Never drive faster than 80 km/h
(50 mph) with a spare wheel fitted on
the car.

•

The car must never be driven fitted
with more than one "Temporary Spare"
wheel.

•

The car may have different driving cha-
racteristics while driving with the spare
wheel. The spare wheel must be
replaced with a normal wheel as soon
as possible.

•

The spare wheel is smaller than the
normal wheel, which affects the car's
ground clearance. Look out for high
kerbs and do not machine-wash the
car.

•

Follow the manufacturer's recom-
mended tyre pressure for the spare
wheel.

•

On all-wheel drive cars, the drive on
the rear axle can be disengaged.

•

If the spare wheel is fitted to the front
axle then it is not possible to use snow
chains at the same time.

•

The spare wheel must not be repaired.

IMPORTANT

The car must not be driven with tyres of
different sizes or with a spare tyre other
than the one supplied with the car. Using
different-sized wheels can cause serious
damage to the car's transmission.

Handling the spare wheel

Follow these instructions for handling the
spare wheel.

The illustration is generic and appearance may differ.

The spare wheel is stored in a bag and must
be secured with two straps on the floor of the
cargo area while driving. The straps must be
tensioned crosswise over the wheel and
attached in the car's four load retaining eye-
lets.

Tools for changing wheels are located under
the cargo area floor.

Winter tyres

Winter tyres are adapted for winter road con-
ditions.

Volvo recommends winter tyres with particu-
lar dimensions. Tyre dimensions are depend-
ent on engine variant. When driving on winter
tyres, the correct type of tyres must be fitted
to all four wheels.

NOTE

Contact a Volvo dealer for advice about
which wheel rim and type of tyre are most
suitable.

Tips for changing to winter tyres

When summer and winter wheels are
changed, mark which side of the car they were
mounted on, for example

L

for left and

R

for

right.

Studded tyres

Studded winter tyres should be run in gently
for 500-1000 km (300-600 miles), so the
studs settle properly into the tyres. This gives
the tyre, and especially the studs, a longer
service life.

NOTE

The legal provisions for the use of studded
tyres vary from country to country.

Tread depth

Road conditions with ice, slush and low tem-
peratures place considerably higher demands
on tyres than summer conditions. Volvo there-
fore recommends not to drive on winter tyres
that have a tread depth of less than 4 mm
(0.15 inches).

Snow chains

Use of snow chains and/or winter tyres can
help to improve the traction in winter condi-
tions.

Volvo recommends that snow chains are not
used on wheel dimensions greater than
18 inches

WARNING

Use Volvo genuine snow chains or equiva-

lent chains designed for the car model, and

tyre and rim dimensions. Only

single-sided

snow chains are permitted.
In the event of uncertainty about the show

chain, Volvo recommends that an author-

ised Volvo workshop should be contacted.

The wrong snow chains may cause serious

damage to the car and lead to an accident.

IMPORTANT

Snow chains can be used on the car with
the following restrictions:

•

Always follow the mounting instruc-
tions from the manufacturer carefully.
Fit the chains as tensioned as possible
and tension them at regular intervals.

•

Snow chains must only be used on the
front wheels (also applies to all-wheel
drive cars).

•

In some cases, snow chains must NOT
be used, such as if accessory, after-
market or "special" tyres and wheels
are fitted that have a different size to
the original tyres and wheels. Suffi-
cient distance must be maintained
between the chains and brakes, sus-
pension and body components.

•

Check local regulations with regard to
using snow chains before fitting them.

•

Never exceed the chain manufacturer's
specified maximum speed. You must
never exceed 50 km/h (30 mph) under
any circumstances.

•

Avoid bumps, holes or sharp turns
when driving with snow chains.

•

Avoid driving on bare ground as this
wears out both the snow chains and
tyres.

•

Driving with snow chains may have a
negative effect on the car's driving
characteristics. Avoid fast or sharp
turns, as well as braking with locked
wheels.

•

Some types of chain that are firmly
tensioned affect brake components
and must therefore NOT be used.

You can obtain more information on snow
chains from a Volvo dealer.

Emergency puncture repair kit

The emergency puncture repair kit

7

, is used

to seal a puncture as well as to check and
adjust the air pressure in the tyre.

Cars equipped with spare tyre

*

do not have

the puncture repair kit.

The puncture repair kit consists of a compres-
sor and a bottle with sealing fluid. The sealing
works as a temporary repair.

NOTE

The sealing fluid is effective at sealing tyres
with tread punctures but has limited ability
to seal tyres with sidewall punctures. Do
not use the emergency puncture repair kit
on tyres displaying larger slits, cracks or
similar damage.

NOTE

The compressor is intended for temporary
emergency puncture repair and is
approved by Volvo.

Location

The puncture repair kit is located in the foam
block under the floor in the cargo area.

Sealing fluid expiry date

The bottle of sealing fluid must be replaced if
the bottle's expiry date has passed (see the
decal on the bottle). Treat the old bottle as
environmentally hazardous waste.

with a reverse catch to prevent leakage.

6. Unscrew the tyre's dust cap and screw in

the air hose's valve connection to the bot-
tom of the thread on the tyre's air valve.

Check that the pressure reducing valve on
the air hose is fully screwed in.

7. Connect the electrical cable to the closest

12 V socket and start the car.

NOTE

Make sure that none of the other 12 V
sockets is in use when the compressor is
operating.

WARNING

Do not leave children in the car without

supervision when the engine is running.

WARNING

Inhaling car exhaust fumes could result in

danger to life. Never leave the engine run-

ning in sealed areas or areas that lack suffi-

cient ventilation.

8. Start the compressor by flicking the

switch to position

I

(On).

WARNING

Never stand next to the tyre when the

compressor is running. If cracks or uneven-

ness arise then the compressor must be

switched off immediately. The journey

should not be continued. Call roadside

assistance for recovery to a tyre centre.

Volvo recommends an authorised tyre cen-

tre.

NOTE

When the compressor starts, the pressure
can increase up to 6 bar (88 psi) but the
pressure drops after approximately
30 seconds.

9. Inflate the tyre for 7 minutes.

IMPORTANT

The compressor must not be operated for
longer than 10 minutes - risk of overheat-
ing.

10. Switch off the compressor to check the

pressure on the pressure gauge. Minimum
pressure is 1.8 bar (22 psi) and maximum
is 3.5 bar (51 psi). Release air using the
pressure reducing valve if the tyre pres-
sure is too high.

WARNING

If the pressure is below 1.8 bar (22 psi)

then the hole in the tyre is too big. The jour-

ney should not be continued. Call roadside

assistance for recovery to a tyre centre.

Volvo recommends an authorised tyre cen-

tre.

11. Switch off the compressor and detach the

electrical cable.

12. Unscrew the air hose from the tyre valve

and refit the dust cap on the tyre.

NOTE

•

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

•

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

13. Fit the protective cap on the air hose in

order to avoid leakage of the remaining
sealing fluid. Place the equipment in the
cargo area.

14. As soon as possible, drive at least 3 km

(2 miles) at a maximum speed of 80 km/h
(50 mph) so that the sealing fluid can seal
the tyre, and then perform a follow-up
check.

WARNING

Sealant will spurt out of the puncture dur-

ing the first few rotations of the tyre. Make

sure that nobody is standing near the car

and gets the sealing fluid splashed onto

them when the car is driven away. The dis-

tance should be at least 2 metres (7 feet).

15.

Follow-up inspection

Connect the air hose on the tyre valve and
screw in the valve connection to the bot-
tom of the tyre valve's thread. The com-
pressor must be switched off.

16. Read the tyre pressure on the pressure

gauge.

•

If it is below 1.3 bar (19 psi) then the
tyre is insufficiently sealed. The journey
should not be continued. Call roadside
assistance for recovery.

•

If the tyre pressure is higher than
1.3 bar (19 psi), the tyre must be infla-
ted to the pressure specified in accord-
ance with the tyre pressure label on the
driver's side door pillar (1 bar = 100 kPa
= 14.5 psi). Release air using the pres-
sure reducing valve if the tyre pressure
is too high.

WARNING

Check the tyre pressure regularly.

Volvo recommends that the car is driven to the
nearest authorised Volvo workshop for the
replacement/repair of the damaged tyre.
Advise the workshop that the tyre contains
sealing fluid.

The sealing fluid bottle and hose must be
replaced after use. Volvo recommends that
these replacements be performed by an
authorised Volvo workshop.
