Wheels and tyres -&gt; Checking tyre pressure for your Volvo XC40 2018-2026

Tyre pressure monitoring system *

After a tyre has been inflated, always

refit the dust cap in order to avoid dam-

age to the valve from gravel, dirt, etc.

•

(p. 533)

Tyres (p. 526)

•

Only use plastic dust caps. Metal dust

caps can rust and become difficult to

unscrew.

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.

4. Check the tyres visually for any implanted

nails or other objects that could puncture

the tyre and cause leakage.

5. Check the sidewalls for any cavities, cuts,

bumps or other irregularities.

6. Repeat this for all tyres, including the

spare tyre*.

1. Remove the cap from the valve on one

tyre and then press the tyre pressure

gauge firmly down onto the valve.

If you have over-inflated, release air by

pressing in the metal pin in the centre of

the valve. Then check the pressure again

using the tyre pressure gauge.

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.

Some spare tyres require a higher tyre

pressure than other tyres. Check in the tyre

pressure table or on the tyre pressure label.

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 pres-

sures can be chosen for good fuel economy.

However, the lower comfort pressures are rec-

ommended instead if improved noise and trav-

elling comfort are desired.

locations in the car. The information that

applies to your particular car can be found

WHEELS AND TYRES

Each tyre, including the spare tyre*, should be

checked once a month. When checking, the

tyre should be cold and have the air pressure

recommended by the car manufacturer speci-

fied on the tyre pressure label or in the tyre

pressure table. If the car has tyres of a differ-

ent size than that recommended by the manu-

facturer, find out what the correct air pressure

level is for these.

system fault indicator is combined with the

indicator symbol 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 ability to detect or

warn of low tyre pressure may be affected.

Tyre pressure monitoring system*

The tyre pressure monitoring system³gives 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.

This symbol illuminates to indicate

low tyre pressure. Check the tyre

pressure in the Car Status app in

the centre display.

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 indica-

tor symbol for low air pressure is lit, stop and

check the tyres as soon as possible and inflate

to the correct air pressure.

A TPMS system fault can occur for several

reasons, such as after changing to a spare

tyre, or changing tyres or wheels that prevent

TPMS from functioning correctly.

If there is a fault in the system the tyre pres-

sure warning symbol flashes for approximately

one minute and then remains illuminated.

System description

Always check the indicator symbol for TPMS

after changing one or more tyres in order to

ensure the new tyre or wheel is working cor-

rectly with TPMS.

The tyre pressure monitoring system meas-

ures 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 pressure is too

low, the tyre's diameter is changed and, as a

result, so is its rotation speed. By comparing

the tyres with each other the system can

determine whether one or more tyres have

pressure that is too low.

Driving with tyres that have tyre pressure that

is too low may cause the tyre to overheat,

which can cause a tyre failure. Low tyre pres-

sure 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 driv-

er'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.

To bear in mind

Always save a new tyre pressure in the

system after changing a wheel or adjust-

ing tyre pressure.

•

If you change to tyres of a different size to

the ones fitted at the factory, the system

must be reset by storing a new tyre pres-

sure for these tyres to avoid false warn-

ings.

•

General information on the tyre monitoring

system

In the information below, the tyre monitoring

system is referred to generically as TPMS.

If a spare wheel* is used, it is possible that

not work correctly due to the differences

between the wheels.

Saving a new tyre pressure in the

monitoring system*

The car must be stationary for the Store

Pressure button to be selectable.

In order for the system for tyre pressure

monitoring⁴to 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.

The system does not replace the need for

regular tyre inspection and maintenance.

It is not possible to switch off the tyre

pressure monitoring system.

Spare wheel*

WARNING

The spare wheel, the Temporary Spare type,

can be used to temporarily replace a punc-

tured normal wheel.

The spare wheel is only designed for tempo-

rary use. Replace it with a normal wheel as

soon as possible.

Never drive faster than 80 km/h

(50 mph) with a spare wheel fitted on

the car.

•

Remember not to use bending force when

you loosen/tighten the wheel bolts. This

could damage the code groove in the lock

bolt and the wheel wrench and so make it

impossible to fit/remove the wheel.

The car must never be driven fitted

with more than one "Temporary Spare"

wheel.

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.

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.

When the wheel wrench is not in use it must

be stored in its place in the foam block under

the cargo area floor. It is important to remem-

ber this if the car is due to visit a workshop in

order to have the tool available. If you lose the

wrench, contact your Volvo dealer.

Recommended tyre pressure must be main-

tained regardless of the position of the tempo-

rary spare wheel on the car.

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.

Handling the spare wheel*

Follow these instructions for handling the

spare wheel.

Storing the punctured tyre

1. Screw back the mounting screw that held

the spare wheel in place.

The car must not be driven with tyres of

different sizes or with a spare wheel other

than the one supplied with the car. Using

different-sized wheels can cause serious

damage to the car's transmission.

Do not attempt to unscrew the lower part

of the mounting screw if it is secured in the

body. There is a risk it may break.

2. Put the tools back in their right place in

the foam block.

The spare wheel is located under the cargo

area floor in the spare wheel well with the out-

side down. The foam block contains all the

tools for changing a wheel.

3. Then fold down the cargo area floor and

place the punctured tyre in the cargo area.
