2. Vacuum the mats and floor to remove loose dust and dirt. Do not shake or beat the mats to remove dust and dirt as they can

crack.

3. Clean the area with a neutral-coloured, clean microfibre cloth that is lightly dampened with water or a colourless, mild

cleaning agent. Use gentle circular motions.

4. Let the mat dry fully before putting it back. Fix it into place by pressing down near each pin.

Warning

Only use one mat for each seat and make sure the mats are properly fastened using all pins. If the driver's mat is not

properly attached, it can move around and endanger your driving by getting caught near or under the driver pedals.

13.4. Wheels and tyres

The tyres' purpose is to carry your car's load, grip the underlying surface well, reduce vibration and protect

the wheel rim from wear. Get familiar with the recommendations to get the most out of your wheels and

tyres.

Familiarise yourself with tasks such as how to maintain a correct tyre pressure and how to change wheels so you are comfort-

able in these situations.

13.4.1. Wheel and tyre recommendations

The content of this manual represents the status of the user manual at the time of printing and may not be completely valid in future

instances. For more information, refer to the first page for the complete disclaimer note.

342 / 444

Volvo recommends that you only use wheel rims and tyres that have been tested and approved by Volvo and

are genuine Volvo accessories. A complete wheel refers to when tyres are fitted onto wheel rims.

Recommended tyres

On delivery, the car is equipped with Volvo original tyres that have the VOL marking on their sides^[1]. These tyres are carefully

adapted to the car. It is therefore important that if you change tyres, the new tyres also have this marking in order to maintain

the car's driving characteristics, comfort and electricity consumption.

Original tyres

Your car is originally equipped with tyres according to the label found on the pillar by the driver door.

The tyres have good roadholding properties and provide good driving characteristics on dry and wet road surfaces. Remember,

however, that the tyres have been developed to provide these properties on roads that are free from ice and snow.

Some cars are equipped with a combination of tyres and wheel rims with extra-high performance. They are designed to be cap-

able on dry road surfaces and with resistance against aquaplaning. These may be more sensitive to damage on the road surface

and, depending on conditions, may have a service life of less than 30,000 km (20,000 miles). Even if the car is equipped with

AWD or stability systems, these tyres are not designed for winter driving and should be changed to winter tyres as the weather

requires.

"All-season" tyres provide slightly better roadholding on slippery road surfaces than tyres without the "all-season" classifica-

tion. However, for good roadholding on icy or snow-covered roads, Volvo recommends winter tyres on all four wheels.

Tyre age

Volvo recommends that tyres should be changed after 6 years of normal use. Tyres age and deteriorate over time, even if they

are rarely or never used. The function can therefore be affected. This applies to all tyres that are stored for future use. Heat

caused by hot climates, frequently carrying heavy loads or exposure to ultraviolet (UV) radiation may accelerate the ageing pro-

cess. Cracks or discolouration are examples of external signs which indicate that the tyre is unsuitable for use. A tyre that has

visible signs of deterioration should be changed immediately.

When you replace your tyres, it is important to use the newest tyres possible. This is especially important with regard to winter

tyres. Use the tyres' DOT^[2]markings to determine how old your tyres are.

Replacing tyres

Never switch originally fitted wheels between the front and rear axles.

When you replace your tyres, you must make sure that all four tyres have the right size designation for their corresponding axle,

are of the same type (radial), and are preferably from the same manufacturer as the original tyres. Otherwise there is a risk of

changing the car's roadholding properties and driving characteristics.

The wheel must always rotate in the same direction throughout its lifespan.

If the wheels are fitted incorrectly, the car's braking characteristics and capacity to deflect rain and slush are adversely affected.

Wheel rims and tyre sizes

The content of this manual represents the status of the user manual at the time of printing and may not be completely valid in future

instances. For more information, refer to the first page for the complete disclaimer note.

343 / 444

Warning

Your Volvo's wheel rim and tyre sizes are specified to meet stringent requirements for stability and driving

characteristics. Unapproved combinations of wheel rim size and tyre size may have a negative effect on the car's

stability and driving characteristics.

Any damage caused by the fitting of unapproved combinations of wheel rim size and tyre size are not covered by the

new car warranty. Volvo accepts no liability for death, personal injury or any costs caused by such installations.

Do not use steel or aluminium wheel rims which are damaged, cracked or deformed, which have extensive corrosion

damage, or which have been welded or repaired.

13.4.1.1. Tyres and wheel storage

To keep them in good condition, you should always store wheels that are not in use in a cool, dry and dark

place. How you place them, as well as avoiding exposure to chemicals, is also important.

When you store wheels that are not in use, it's important to keep them from direct sunlight, rain, water, heat sources or sparks.

They should never be stored near solvents, petrol, oils or similar substances, especially not flammable ones.

Store wheels^[1]hung up or lying on their sides on the floor.

If you store tyres not fitted on rims, you should never hang them up. Store them standing upright or lying on their sides in-

stead. If you hang up rimless tyres, they may become deformed.

[1]

Tyres fitted on rims

13.4.1.2. Tyre economy

To preserve your tyres as much as possible, there are some things you should keep in mind.

Correct tyre pressure reduces uneven wear. It's important to check the pressure regularly.

Hard acceleration, heavy braking and driving in a way which causes screeching tyres lead to increased tyre wear.

Tyre wear increases with speed.

Unbalanced wheels cause uneven and excessive tyre wear as well as reduced ride comfort.

Wheels must have the same direction of rotation during their entire service life.

The rear tyre grip should always be equal to, or better than, the front tyre grip to reduce the risk of oversteering in case of

heavy braking.

instances. For more information, refer to the first page for the complete disclaimer note.

344 / 444

Tyres or wheel rims may be damaged permanently if you hit kerb stones or drive into deep holes.

Driving style, road conditions and climate affect the tyre wear.

13.4.2. Designations on tyre sidewall

There are many digits, numbers and symbols that may be found on a tyre's sidewall. Here are some examples

and explanations of what they indicate.

13.4.2.1. Tyre tread wear indicators

The content of this manual represents the status of the user manual at the time of printing and may not be completely valid in future

instances. For more information, refer to the first page for the complete disclaimer note.

346 / 444

There are tread wear indicators to show the status of the tyre's tread depth.

The narrow grooves that run lengthways across the tyre's tread pattern are tread wear indicators. On the side of the tyre are the

letters TWI^[1]

.

Important

Tyres should be changed before wearing them down to the tread wear indicators to avoid poor traction in rain and

snow.

Volvo recommends that winter tyres have a greater tread depth than 3 millimetres (1/8 inch) and summer tyres

1.6 millimetres (1/16 inch).

13.4.3. Changing wheels

If you need to change a wheel, it's important to follow the recommended procedure.

Warning

Raising the car to change a wheel

Changing a wheel requires that you raise the wheel off the ground. Carefully follow the separate instructions for raising

the car safely.

If you are changing a wheel in or close to traffic, make sure you and the car are clearly visible to others. Activate the

hazard warning lights, put out a warning triangle in a visible but safe place and wear a reflective vest.

Designate a safe space for passengers to wait, away from both the car and traffic.

You are responsible for safety around the car while it is raised. Do not allow people inside or close to the car.

Never get under the car, or let anyone reach under it with any part of their body, while it is raised with a jack.

The content of this manual represents the status of the user manual at the time of printing and may not be completely valid in future

instances. For more information, refer to the first page for the complete disclaimer note.

347 / 444

Note

You must activate jack mode before raising the car off the ground.

Before removing the wheel

The wheels on your car are fastened with wheel bolts. For extra security, you can use lockable bolts.

Put the gear in P and engage the parking brake before starting.

Important

Make sure that the dimensions of the replacement wheel are approved for your car.^[1]

Make sure you read through all the instructions before you start. Get all the tools you need before the car is raised.^[2]

Removing the wheel

1. Remove the plastic caps from the wheel fasteners using a suitable tool or pull the wheel cap off.

Tool for removing the wheel fastener caps

2. While your car is still on the ground, use the wheel wrench to loosen the wheel fasteners approximately 0.5-1 turn. Press

the wrench downwards while the wrench is extended to the left to avoid personal injury. The anticlockwise rotation loosens

the fastener. If you are using lockable bolts, start with them.

3. Follow the instructions on how to safely raise the car.

4. Raise the car high enough so that the wheel you want to remove is off the ground. Remove the wheel fasteners and lift off

the wheel.

Tip

When switching wheels between winter and summer, mark which side they were mounted on, for example L for left

and R for right.

348 / 444

6. Mount the wheel. Make sure you tighten the fasteners. However, the final tightening to the specified torque is done when

the wheel is back on the ground and unable to rotate while you do it.

Warning

Never switch originally fitted wheels between the front and rear axles.

Make sure that you put the wheels on the correct axle. Incorrectly mounted wheels can affect the car's handling.

Never use lubricant on the threads of wheel fasteners. It could cause the wheel fasteners to loosen after

tightening.

7. Lower the car back to the ground.

8. Fasten the fasteners crosswise. If you are using lockable bolts, finish with those.

It’s very important that the fasteners are properly secured. Tighten to 140 Nm (103 lb-ft). Check the tightening torque with a

torque wrench. Overtightened or loosely tightened fasteners may damage the fastening threads or the wheel itself.

Tighten the wheel fasteners crosswise.

9. Place the wheel fastener cover back over the fasteners, using the guide markers to position it correctly, then press it into

place. Ensure that it's securely fastened.

10.Check the tyre pressure and store a new reference value in the tyre pressure monitoring system.

Warning

Check the wheel fasteners

The wheel fasteners may need to be re-tightened a few days after the wheel has been changed. Temperature differences

and vibrations may cause them to loosen.

Wheel properties after a wheel change

Be attentive to signs of incorrectly fitted wheels. This could affect the car's braking characteristics and the ability to de-

flect rain and slush.

When you have changed the type or size of the wheels, you should drive carefully at first. The dynamics and driving char-

acteristics of the wheels may have changed.

Some spare wheels have different dimensions. If your car is approved for the spare wheel you intend to use, the difference

in dimensions is okay.

Use tools that are designed for your car model.

13.4.3.1. Spare wheel

If you get a punctured tyre, a spare wheel^{[ ]}can be temporarily used until the original wheel can be replaced

1

or repaired.

The spare wheel is only designed for temporary use. You should replace the spare wheel with an ordinary wheel as soon as

possible.

Warning

Before driving with a spare wheel

Only use a spare wheel that your car is approved for.

Never drive your car with more than one spare wheel fitted.

Snow chains cannot be used if the spare wheel is fitted on the front axle.

The spare wheel should never be repaired.

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

Make sure to follow the spare wheel manufacturer’s recommendations regarding tyre pressure.

Driving with a spare wheel

Never drive faster than 80 km/h (50 mph) when a spare wheel is fitted to your car.

Your car's driving characteristics may be affected by using a spare wheel. It is important to replace the spare wheel

with an original wheel as soon as possible.

Note

While a spare wheel is used, the tyre pressure monitoring system might not work correctly.

[1]

The spare wheel must be of the type Temporary Spare.

13.4.3.2. Winter tyres

The content of this manual represents the status of the user manual at the time of printing and may not be completely valid in future

instances. For more information, refer to the first page for the complete disclaimer note.

350 / 444

Winter tyres are designed for driving in road conditions with ice and snow. Your winter tyres' tread depth

should be deeper than that of regular tyres.

Dimensions

When driving with winter tyres, it's important that all four tyres are of the correct type. Contact a Volvo dealer for advice.

Studded tyres

Studded winter tyres should be run-in gently for 500-1,000 km (300-600 miles) so that the studs settle properly into the

tyres. This gives the tyre, and especially the studs, a longer service life.

Note

Legal regulations for the use of studded tyres may vary. Make sure your fitted tyres are in full compliance with local

regulations and laws.

Tread depth

Road conditions with ice, slush, snow and low temperatures put higher demands on your tyres than summer conditions. Volvo

recommends that winter tyres have a tread depth of at least 4 millimetres (0.15 inch).

Note

Speed rating

Winter tyres^[1]are allowed to have a lower speed rating than your car's top speed. However, if your winter tyres do have a

lower speed rating than your car's top speed, you are not allowed to drive faster than the tyres' speed rating.

[1]

Both studded and stud-free tyres

13.4.3.3. Using snow chains

Using snow chains can help to improve traction in winter conditions. However, there are some restrictions

you have to keep in mind.

Warning

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

Use genuine Volvo snow chains or equivalent chains designed for the car model, tyre and wheel rim dimensions.

Only single-sided snow chains are permitted.

The wrong snow chains may cause serious damage to the car and lead to an incident.

The content of this manual represents the status of the user manual at the time of printing and may not be completely valid in future

instances. For more information, refer to the first page for the complete disclaimer note.

351 / 444

Note

Using snow chains may result in malfunction of the tyre pressure monitoring system.

Fitting snow chains

Make sure you are in a safe place when fitting or removing the snow chains.

•

Always comply with local regulations and laws regarding the use of snow chains.

•

Always carefully follow the mounting instructions from the manufacturer.

•

Always use the same type of chains on left and right-hand side tyres.

•

Volvo recommends that snow chains are not used on wheels with dimensions greater than 20 inches.

•

Make sure you use the correct size in relation to the wheels.

•

Snow chains must only be used on the rear wheels.^[1]

•

If wheels of a different size than the original wheels are fitted, certain snow chains must not be used.

•

There needs to be sufficient distance between the chains and the car's brakes, suspension and body components. Chains

•

that risk interfering with brake components must not be used.

If you need to move your car while fitting or removing chains, do not let the wheels run over the chains' attachments.

•

Fit the chains as tensioned as possible and tension them at regular intervals.

•

Tip

Practise fitting the snow chains before winter comes.

Driving with snow chains

Once the snow chains are fitted, drive about 200 metres (650 feet). Then stop the car and check again that the chains are

•

firmly attached.

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

•

circumstances.

While improving grip in certain conditions, snow chains negatively affect other driving characteristics. If possible, avoid

•

driving over uneven ground, such as bumps or holes. Also avoid fast or sharp turns as well as hard braking.

Avoid driving on ground not covered in snow or ice as this wears out both the snow chains and wheels.

•

Contact a Volvo dealer for more information.

13.4.4. Punctures

If you suffer a punctured tyre, there are several actions to take to recover safely, especially if it happens while

you are driving.

If the puncture occurs while you are driving, it’s important to think about safety first. Activate the hazard warning lights and, if

possible, move the car away from immediate danger. If necessary, call roadside assistance.

Warning

Do not drive the car if it has a punctured tyre. It is not safe and will damage the car.

If possible, exit your car from the side with the least traffic to avoid causing an accident.

Place a warning triangle so that others are warned well in advance of passing your car. Remember to first put on a

reflective vest if you have one.

Tip

If you need to use a temporary puncture repair kit, be sure to read its instructions before you start to use it.

13.4.4.1. Temporary puncture repair

Your car is equipped with a temporary puncture repair kit^{[ ]}which can be used to repair a minor puncture in

1

a tyre. The kit includes a bottle of sealant fluid and a compressor.

Warning

Read through all of the instructions before using the repair kit.

You should not drive faster than 80 km/h (50 mph) after the repair kit has been used on your tyres.

The content of this manual represents the status of the user manual at the time of printing and may not be completely valid in future

instances. For more information, refer to the first page for the complete disclaimer note.

353 / 444

Compressor

The compressor is intended to be used for temporary tyre repair and is approved by Volvo. You can also use the compressor to

check and adjust the tyre pressure on your original tyres when needed.

The compressor is an electrical device. When it's time to dispose of it, be sure to follow local regulations related to waste

management.

Sealant fluid

The sealant fluid works as a temporary repair. It is effective at sealing a tread puncture but should not be used to seal a puncture

in the sidewall of the tyre. If the tyre has larger slits, cracks or similar damage, you should not use the sealant to repair it.

The bottle of sealant fluid needs to be replaced if the expiration date has passed^[2]. The old bottle is considered hazardous

waste.

[1]

Also called temporary mobility kit or TMK

[2]

See expiration date on bottle.

13.4.4.1.1. Using the temporary puncture repair kit

When using the temporary puncture repair kit, there are a number of important steps you need to follow.

Make sure you read and understand each step before proceeding.

Warning

Sealing fluid can be harmful

The sealing fluid contains substances that are harmful if swallowed. The contents can also cause allergic reactions or be

otherwise harmful to the respiratory tract, the skin, the central nervous system and the eyes.

Precautions

Store the kit out of reach of children.

Avoid prolonged or repeated contact with the skin. If you get sealing fluid on your clothes, remove them.

Wash hands thoroughly after handling.

First aid

Ingestion: Do not induce vomiting unless directed to do so by medical personnel. Get medical attention.

Skin: Wash affected areas of skin with soap and water. Get medical attention if symptoms occur.

Eyes: Flush with plenty of water for least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical

attention if symptoms occur.

Inhalation: Move the exposed person to fresh air. If irritation persists, get medical attention.

Make sure the compressor's power button is in the off position before starting.

Don't remove the air hose during repair.

If the puncture was caused by a nail or similar and it's still in the tyre, leave it in. This helps to seal the puncture.

If the repair is carried out in an area where there might be other vehicles, activate the hazard warning lights and use a

warning triangle, if you have one.

Preparations

1. Place the label showing maximum permitted speed so that it is clearly visible as a reminder for the driver, for example in the

5. Connect the compressor to the car's 12 V socket and ensure that the socket works and is supplying current.

6. Start the compressor by pressing the power button.

>

The compressor pressure increases. The pressure may temporarily reach as high as 7 bar (102 psi) before settling after about

30 seconds.

Warning

Never stand next to the tyre while the compressor is on. If cracks or bumps appear in the tyre, the compressor must

be turned off immediately. Stop and contact Volvo Assistance for safe recovery.

7. Inflate the tyre for 7 minutes.

Important

To avoid overheating, do not run the compressor for more than 10 minutes.

8. Shut the compressor off to check the pressure on the pressure gauge. The minimum tyre pressure is 1.8 bar (26 psi) and the

maximum tyre pressure is 2.5 bar (36 psi). Use the pressure-reducing valve if the pressure is too high.

You need to remove the bottle to access the air release valve. The bottle is equipped with a check valve that prevents fluid

leakage when the bottle isn't connected to the compressor, so you don't have to worry about fluid leaking out. Follow these

steps to remove the bottle:

1. Unscrew the hose from the tyre's valve.

2. Detach the hose from the bottle.

3. Remove the bottle from the compressor.

4. Attach the hose directly to the compressor.

5. Screw the hose back onto the tyre's valve.

6. Release air by pressing the air release valve.

Warning

If the pressure is below 1.8 bar (26 psi), the hole in the tyre is too big. Do not continue and contact Volvo Assistance

for safe recovery.

9. Unplug the compressor from the 12 V socket.

10.Clean the hose before stowing it and make sure that no sealing compound is spilt.

11. Refit the tyre valve's dust cap.

12. As soon as possible, drive for 10 minutes^[1]and let the fluid seal the tyre. After that, perform a follow-up check.

Warning

Sealant will squirt out of the puncture during the first few rotations of the tyre. Make sure that nobody is standing

near the car and gets the sealing fluid on them when the car is driven away.

Follow-up check

13.With the compressor shut off, connect the air hose to the tyre's air valve.

14.Check the tyre pressure on the pressure gauge.

>

If it is below 1.3 bar (19 psi) then the tyre is insufficiently sealed. Stop and contact Volvo Assistance for safe recovery.

If the tyre pressure is higher than 1.3 bar (19 psi), the tyre must be inflated to the pressure specified on the tyre pressure

label on the driver's side door pillar. If the pressure is too high, release air using the pressure-reducing valve.

15. Refit the tyre valve's dust cap.

Replace the sealing fluid bottle and hose after use. Contact a Volvo dealer to do so.

Volvo recommends replacing or repairing the damaged tyre as soon as possible. Inform the workshop that the tyre contains

sealing fluid.

Warning

Maximum mileage with tyres containing sealing fluid is 200 km (120 miles).

3. Connect the compressor to the car's 12 V socket and start the car.

4. Start the compressor by pressing the power button.

Important

To avoid overheating, do not run the compressor for any longer than 10 minutes at a time.

5. Check the tyre pressure on the compressor's pressure gauge^[1]. Use the pressure-reducing valve if the pressure is too high.

6. Turn off the compressor and unplug it from the 12 V socket.

7. Unscrew the air hose from the tyre.

8. Refit the tyre valve's dust cap.

9. Store a new reference value in the tyre pressure monitoring system if needed.

Return the kit to its storage location.

[1]

The recommended tyre pressure for the car's original tyres can be found on a label on the driver's side door pillar.

13.4.5. Tyre pressure

A correct tyre pressure helps to improve driving stability, lower energy consumption and extend the lifespan

of the tyre.

With time, the tyre pressure decreases. The pressure also varies depending on environmental conditions. All of this is normal.

However, if you drive with an incorrect tyre pressure, the tyres may overheat and become damaged. The tyre pressure affects

ride comfort, noise levels and handling characteristics.

Make it a habit to check the tyre pressure monthly and before longer trips. Always make sure you use a reliable pressure gauge.

To keep the tyres in good shape, use the recommended tyre pressure for cold tyres.

The content of this manual represents the status of the user manual at the time of printing and may not be completely valid in future

instances. For more information, refer to the first page for the complete disclaimer note.

358 / 444

Warning

If the tyre pressure is too high or too low, the tyres can sustain severe damage. The tyres can explode while you are

driving and cause you to lose control of the car.

Tip

A correct tyre pressure will help you take advantage of your car's full loading capacity.

13.4.5.1. Tyre pressure monitoring

Your car can detect and indicate if the tyre pressure is low. Tyre pressure monitoring cannot be disabled. If

the system is unable to detect any tyre pressure, it will indicate that there's a malfunction.

For the tyre pressure monitoring system to provide updated information, you need to drive the car above 35 km/h (22 mph) for

several minutes.

An indicator symbol lights up if a low tyre pressure is detected in any of the tyres. It will stay illuminated until the problem is re-

solved and a new reference value for the tyre pressure has been stored.

In addition to messages in the driver display, you can also find information about the tyre pressure monitoring in the car status

view.

Warning

No advance warning possible

The system cannot give you any advance warning of potential tyre damage.

Ensure correct tyre pressure immediately

When the low tyre pressure symbol is lit, stop and check the tyre pressures as soon as possible. Driving with underin-

flated tyres can cause tyre failure.

If the tyre pressure monitoring system is not working correctly, the driver display's indicator symbol will first flash for approx-

imately one minute and then remain lit. A message also appears on the driver display. If the fault is permanent, a service is re-

quired.^[1]

Remember that the system does not replace the need for regular tyre inspection and maintenance.

System description

Note

Your car uses an indirect tyre pressure monitoring system. This means you don't need to use wheels mounted with

TPMS^[2]sensors.

The following information is phrased according to external legal requirements.

Each tyre, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recom-

mended by the vehicle manufacturer on the vehicle placard or tyre inflation pressure label. (If your vehicle has tyres of a differ-

ent size than the size indicated on the vehicle placard or tyre inflation pressure label, you should determine the proper tyre infla-

tion pressure for those tyres.)

As an added safety feature, your vehicle has been equipped with a tyre pressure monitoring system (TPMS) that illuminates a

low tyre pressure telltale when one or more of your tyres is significantly under-inflated. Accordingly, when the low tyre pressure

telltale illuminates, you should stop and check your tyres as soon as possible, and inflate them to the proper pressure. Driving

on a significantly under-inflated tyre causes the tyre to overheat and can lead to tyre failure. Under-inflation also reduces fuel ef-

ficiency and tyre tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tyre maintenance, and it is the driver's responsibility to maintain correct

tyre pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tyre pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.

The TPMS malfunction indicator is combined with the low tyre pressure telltale. When the system detects a malfunction, the

telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon

subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may

not be able to detect or signal low tyre pressure as intended. TPMS malfunctions may occur for a variety of reasons, including

the installation of replacement or alternate tyres or wheels on the vehicle that prevent the TPMS from functioning properly.

Always check the TPMS malfunction telltale after replacing one or more tyres or wheels on your vehicle to ensure that the re-

placement or alternate tyres and wheels allow the TPMS to continue to function properly.

Note

Certain TPMS malfunctions may require the driver to switch off and lock the vehicle for 6 minutes for the control module

to reset.

If the system still does not work correctly, contact a workshop.^[3]

13.4.5.1.1. Saving a new reference value for tyre pressure

monitoring

The tyre pressure monitoring system needs a reference value to work from. This means that the value needs

to be reset in certain circumstances for the system to work properly.

A new reference value needs to be stored when certain changes have been made, such as every time you adjust the tyre pres-

sure or change the tyres. The reference value may also need to be updated when there is a significant change in the car's weight

due to loading or unloading.

1. Turn the car off.

2. Inflate the tyres to the correct tyre pressure.^[1]

3. Start the car.

4.

Press the car symbol

in the bottom bar and go to Status → Tyre pressure.

5. Select Update reference pressure.

Note

The Update reference pressure button is used to store a new reference value for the tyre pressure monitoring

system. For safety reasons, it's only available when the car is turned on and stationary.

6. Confirm that you want to store a new value. The confirmation step is needed to avoid saving a new reference value by

mistake.

>

This overwrites the previous tyre pressure and enters a new reference value.

7. Start driving the car. The new value will be stored after driving for several minutes at a speed above 35 km/h (22 mph).

>

Once a new reference value is stored, the animation showing the saving progress disappears from the centre display.

If storing fails, an error message is shown.

[1]

See the tyre pressure label on the driver's side door pillar or the relevant section in the manual for information on

recommended tyre pressure for your car.

13.4.5.2. Adjusting tyre pressure

The tyre pressure needs to be adjusted if you're changing wheels or planning to drive with a different load.

It's normal for tyre pressure to decrease over time. Adjusting it so that you have the correct pressure for the

current situation helps ensure an even tyre wear and high performance.

instances. For more information, refer to the first page for the complete disclaimer note.

The tyres need to be at ambient temperature when the pressure is checked and adjusted. This is referred to as having cold tyres.

Never release air from a warm tyre. When it cools down, the internal air pressure drops, which can lead to underinflated or even

entirely deflated tyres.

The tyres can warm up very quickly and should be considered warm if driven for longer than approximately 1.5 km (1 mile). They

often need about 3 hours of cooling down before reaching ambient temperature again.

1. Remove the tyre valve's dust cap and then press the tyre pressure gauge firmly onto the valve.

2. Check the gauge to see what the current tyre pressure is.

3. If the pressure is low, inflate the tyre to the correct pressure. The recommended pressure for factory-fitted tyres is shown on

the door pillar on the driver's side.

4. Refit the dust cap^[1]to avoid damage to the valve.

5. Inspect the tyre for stuck debris, such as nails or other objects, that could puncture the tyre.

6. Check the sidewalls for any cavities, cuts, bumps or other irregularities.

If you accidentally over-inflate the tyre, press the metal pin in the middle of the valve to let out the excess air. Then check the

pressure again.

After adjusting the tyre pressure, remember to store a new reference value in the tyre pressure monitoring system.

Note

Spare wheels may have recommended pressures that are different from those of the original tyres. Always use the

pressure recommended by the spare wheel manufacturer.

Tip

You can use the compressor from the temporary puncture repair kit to check and adjust the tyre pressure on your original

tyres when needed.

[1]

Only use original Volvo dust caps or plastic ones as metal dust caps may corrode and stick to the valve.

13.5. Car electrics and batteries

Your car has a specialised electrical system that delivers electricity to and from the batteries.

There are both high-voltage and low-voltage circuits for different electrical functions.
