Snow tires/studded tires

Owners who live in or regularly commute

through areas with sustained periods of snow

or icy driving conditions are strongly advised

to fit suitable winter tires to help retain the

highest degree of traction.

Tires for winter use:

•

It is important to install winter tires on all

four wheels to help retain traction during

cornering, braking, and accelerating. Fail-

ure to do so could reduce traction to an

unsafe level or adversely affect handling.

•

Do not mix tires of different design as this

could also negatively affect overall tire

road grip.

•

Winter tires wear more quickly on dry

roads in warm weather. They should be

removed when the winter driving season

has ended.

•

Studded tires should be run-in 300 –

600 miles (500 – 1000 km) during which

the vehicle should be driven as smoothly

as possible to give the studs the opportu-

nity to seat properly in the tires. The tires

should have the same rotational direction

throughout their entire lifetime.

, see Tire Monitor - introduc-

Please consult state or provincial regula-

tions restricting the use of studded winter

tires before installing such tires.

Tire pressure monitoring -

introduction

Volvo provides two different systems to moni-

tor tire pressure: Tire Pressure Monitoring

System (TPMS) or Tire Monitor.

Determining which tire monitoring
system is in your vehicle
To see which system is installed in your vehi-

cle, press the MY CAR button on the center
console. Go to

Settings

pressure

, see Tire Pressure Monitoring

System (TPMS) – general information

(p. 306).

Introduction
Each tire, 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 tire inflation pressure label.

(If your vehicle has tires of a different size

than the size indicated on the vehicle placard

or tire inflation pressure label, you should

determine the proper tire inflation pressure for

those tires.)

As an added safety feature, your vehicle has

been equipped with a tire pressure monitor-

ing system that illuminates a low tire pressure
telltale (

) when one or more of your tires

is significantly under-inflated. Accordingly,

when the low tire pressure telltale illuminates,

you should stop and check your tires as soon

as possible, and inflate them to the proper

pressure.
Driving on a significantly under-inflated tire

causes the tire to overheat and can lead to

tire failure. Under-inflation also reduces fuel

efficiency and tire tread life, and may affect

the vehicle's handling and stopping ability.

Please note that a tire pressure monitoring

system is not a substitute for proper tire

maintenance, and it is the driver's responsi-

bility to maintain correct tire pressure, even if

under-inflation has not reached the level to

trigger illumination of the system's low tire

pressure telltale.
Your vehicle has also been equipped with a

TPMS malfunction indicator to indicate when

the system is not operating properly. The

monitoring system's malfunction indicator is

combined with the low tire 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

Where permitted

09 Wheels and tires

306

exists. When the malfunction indicator is illu-

minated, the system may not be able to

detect or signal low tire pressure as intended.
System malfunctions may occur for a variety

of reasons, including the installation of

replacement or alternate tires or wheels on

the vehicle that prevent the tire pressure

monitoring system from functioning properly.
Always check the system's malfunction tell-

tale after replacing one or more tires or

wheels on your vehicle to ensure that the

replacement or alternate tires and wheels

allow the system to continue to function

properly.

table (see Tire inflation – pressure table

The system indicates low tire pressure but

does not replace normal tire maintenance.

For information on correct tire pressure,

please refer to the tire inflation pressure

(p. 300)), the tire inflation pressure placard

located on the driver's side B-pillar (the

structural member at the side of the vehi-

cle, at the rear of the driver's door open-

ing) or consult your Volvo retailer.

WARNING

Incorrect inflation pressure could lead to

tire failure, resulting in a loss of control of

the vehicle.

Tire Pressure Monitoring System

(TPMS) – general information

TPMS uses sensors mounted in the tire valves

to check inflation pressure levels. When the

vehicle is moving at a speed of approximately

20 mph (30 km/h) or faster, these sensors

transmit inflation pressure data to a receiver

located in the vehicle.

USA – FCC ID: KR5S180052050
This device complies with part 15 of the

FCC rules. Operation is subject to the fol-

lowing conditions: (1) This device may not

cause harmful interference, and (2) this

device must accept any interference

received, including interference that may

cause undesired operation.

When low inflation pressure is detected or if a

sensor is not functioning properly, TPMS will
light up the tire pressure warning light (

)

(also referred to as a telltale) in the instrument

panel and will display one of the following

messages:

Tire pressure low

If a malfunction occurs in the system, the

tire pressure warning light will flash for

approximately 1 minute and then remain

illuminated.

Tire Pressure Monitoring System

(TPMS) – changing wheels

Please keep the following in mind when

changing or replacing the factory installed

TPMS wheels/tires on the vehicle:

•

Not all aftermarket wheels are equipped

with TPMS sensors in the valves.

•

If the vehicle is equipped with a tempo-

rary spare tire, this tire does not have a

TPMS sensor.

•

If wheels without TPMS sensors are

mounted on the vehicle, a text message

will displayed in the instrument panel

each time the vehicle is driven above

20 mph (30 km/h) for 10 minutes or more.

•

Once TPMS sensors are properly instal-

led, the warning message should not

reappear. If the message is still displayed,

drive the vehicle for several minutes at a

speed of 20 mph (30 km/h) or faster to

erase the message.

•

Volvo recommends that TPMS sensors

be fitted on all wheels used on the vehi-

cle, including winter tires. Volvo does not

recommend moving sensors back and

forth between sets of wheels.

When inflating tires with TPMS sensors,

press the pump's mouthpiece straight

onto the valve to help avoid bending or

otherwise damaging the valve.

•

After inflating the tires, always reinstall

the valve cap to help avoid damage to

the valve from dirt, gravel, etc.

•

Use plastic valve caps only. Metal

caps could corrode and become diffi-

cult to remove.

•

If you change to tires with a different

dimension than the factory-installed

ones, the TPMS system must be

reconfigured for these tires. This must

be done by a trained and qualified

Volvo service technician.

•

If a tire is changed, or if the TPMS sen-

sor is moved to another wheel, the

sensor's seal, nut, and valve core

should be replaced.

•

When installing TPMS sensors, the

vehicle must be parked for at least

15 minutes with the ignition off. If the

vehicle is driven within 15 minutes, a

TPMS error message will be displayed.

Erasing warning messages
When a low tire pressure warning message

has been displayed and the tire pressure
warning light in the instrument panell (

)

has come on:
1. Use a tire pressure gauge to check the

inflation pressure of all four tires.

2. Re-inflate the tire(s) to the correct pres-

sure (consult the tire pressure placard

located on the driver's side B-pillar (the

structural member at the side of the vehi-

cle, at the rear of the driver's door open-

3. In certain cases, it may be necessary to

drive the vehicle for several minutes at a

speed of 20 mph (30 km/h) or faster. This

will erase the warning text and the telltale

will go out.

•

Tire monitoring systems use a tem-

perature compensated pressure value.

This pressure value is dependent on

tire temperature and ambient tempera-

ture, which can differ from the recom-

mended cold tire pressure in the tire

inflation table and on the tire pressure

placard located on the driver's side B-

pillar (the structural member at the

side of the vehicle, at the rear of the

driver's door opening). This means

that it may sometimes be necessary to

inflate them slightly above the recom-

mended cold pressure value

(approx. 3-4 psi or 0.2-0.3 bar) in order

to reset a low tire pressure warning.

•

To help avoid incorrect tire inflation

pressure, if possible only inflate the

tires when they are cold. The tires are

considered to be cold when they have

the same temperature as the sur-

rounding (ambient) air. This tempera-

ture is normally reached after the vehi-

cle has been parked for at least

3 hours. After driving a distance of

approximately 1 mile (1.6 km), the tires

are considered to be hot.

•

After inflating the tires, always reinstall

the valve cap to help avoid damage to

the valve from dirt, gravel, etc.

•

Use plastic valve caps only. Metal

caps could corrode and become diffi-

cult to remove.

WARNING

•

Incorrect inflation pressure could lead

to tire failure, resulting in a loss of con-

trol of the vehicle.

•

Tire monitoring systems cannot indi-

cate sudden tire damage caused by

external factors (e.g., a blowout) in

advance.

Tire Monitor - introduction

Tire Monitor uses the rotational speed of the

tires in combination with signal analysis of the

ABS sensor signals to determine if they are

properly inflated.

When a tire is under-inflated, its diameter

(and consequently also its rotational speed)

changes. By comparing the individual tires

with each other it is possible to determine if

one or more tires are under inflated.
When low inflation pressure is detected or if

the system is not functioning properly, Tire

Monitor will light up the tire pressure warning
light (

) (also referred to as a telltale) in

the instrument panel and will display one of

the following messages in the text window,

for example:

Tire pressure low Check rear

Tire press. syst Service

required

If two or more tires have low pressure or if the

system cannot determine which tire has low

pressure, a general text (

) will be displayed.

If a malfunction occurs in the system, the

tire pressure warning light will flash for

approximately 1 minute and then remain

illuminated.

pressure reference values must be set. This

must be done each time wheels or tire pres-

sures are changed.

Calibration
1. Switch off the engine.
2. Inflate the tires to the desired pressure

(consult tire pressure placard located on

the driver's side B-pillar (the structural

member at the side of the vehicle) and

Self-supporting run flat tires (SST)

Self-supporting run flat tires are available as

optional equipment on certain models.

The vehicle must be equipped with one of the

tire pressure monitoring systems if tires of

this type are installed.
Tires of this type have specially reinforced

sidewalls that make it possible to continue

driving to a limited extent even though the tire

has lost some or all of its inflation pressure.

These tires are mounted on special rims (nor-

mal tires can also be mounted on these rims).
If an SST tire loses inflation pressure, the yel-

low TPMS symbol illuminates in the instru-

ment panel and a text message is also dis-

played. If this happens, reduce speed to not

more than 50 mph (80 km/h). The tire should

be replaced as soon as possible.

WARNING

•

SST tires should only be mounted by

service technicians who are familiar

with tires of this type.

•

SST tires may only be mounted on

vehicles equipped with a tire pressure

monitoring system.

•

Do not drive faster than 50 mph

(80 km/h) if the monitoring system indi-

cates that a tire has lost inflation pres-

sure.

•

Do not drive farther than 50 miles

(80 km) before replacing a damaged

SST tire.

•

Drive carefully and avoid e.g., hard

braking or fast turns.

•

SST tires must be replaced if they are

damaged. A tire of this type cannot be

repaired.

Tire sealing system* – general

information

Certain models are equipped with a tire

sealing system* that enables you to tempo-

rarily seal a hole in the tread surface and re-

inflate a flat tire, or to adjust a tire’s inflation

pressure.

Introduction
The tire sealing system consists of an air

compressor, a container for the sealing com-

pound, wiring to connect the system to the

vehicle’s electrical system via one of the 12-

volt sockets, and a hose used to connect the

system to the tire’s inflation valve.

The tire sealing system's compressor has

been tested and approved by Volvo.

09 Wheels and tires

314

Option/accessory, for more information, see Introduction.

The 12-volt sockets are located in the front

tunnel console, on the rear side of the center

console in the rear seat and in the cargo

area*.

Accessing the tire sealing system
The tire sealing system is stowed under the

floor of the cargo area. To access it:
1. Lift the floor hatch in the cargo area.
2. Lift out the tire sealing system.

•

The tire sealing system is only

intended to seal holes on the tire’s

tread area, not the sidewall.

•

Tires with large holes or tears cannot

be repaired with the tire sealing sys-

tem.

•

After use, stow the tire sealing system

properly to help prevent rattling.

WARNING

•

After using the tire sealing system, the

vehicle should not be driven farther

than approximately 120 miles (200

km).

•

Have the tire inspected by a trained

and qualified Volvo service technician

as soon as possible to determine if it

can be permanently repaired or must

be replaced.

•

The vehicle should not be driven faster

than 50 mph (80 km/h) while using a

tire that has been temporarily repaired

with the tire sealing system.

•

After using the tire sealing system,

drive carefully and avoid abrupt steer-

ing maneuvers and sudden stops.

Tire sealing system–temporarily
repairing a flat tire

Temporarily repairing a flat tire is done in two

stages:

•

Stage 1: The hole is sealed by pumping

sealing compound into the tire. The car is

then driven a short distance to distribute

the sealing compound in the tire.

09 Wheels and tires

Option/accessory, for more information, see Introduction.

315

Tire sealing system* – overview (p. 315)

Do not remove any foreign objects (nails,

etc.) from the tire before using the sealing

system.

•

Stage 2: The tire’s inflation pressure is

checked and adjusted if necessary.

WARNING

•

Never leave the tire sealing system

unattended when it is operating.

•

Keep the tire sealing system away

from children.

WARNING

The bottle is equipped with a catch to

keep it securely in place and help prevent

sealing compound leakage. Once in place,

the bottle cannot be unscrewed. This must

be done by a trained and qualified Volvo

service technician.

5. Remove the valve cap from the tire’s

inflation valve and screw the tire sealing

system’s hose connector onto the valve

as tightly as possible by hand.

6. Connect the electrical wire to the nearest

12-volt socket in the vehicle.

Be sure that none of the other 12-volt

sockets is being used while the compres-

sor is in operation.

7. Start the vehicle’s engine.

WARNING

The vehicle´s engine should be running

when the tire sealing system is used to

avoid battery drain. Therefore, be sure the

vehicle is parked in a well ventilated place,

or outdoors, before using the system.

8. Start the tire sealing system’s compres-

sor by pressing the on/off switch to posi-

tion I.

WARNING

•

Never stand next to the tire being infla-

ted when the compressor is in opera-

tion.

•

If cracks, bubbles, etc. form on the tire,

switch off the compressor immediately.

•

If there is visible damage to the sidewall

or the rim, the tire cannot be repaired.

The vehicle should not be driven if this

occurs. Contact a towing service or

Volvo On Call Roadside Assistance if

applicable.

The air pressure gauge will temporarily

show an increase in pressure to approxi-

mately 88 psi (6 bar) while the sealing

compound is being pumped into the tire.

The pressure should return to a normal

level after approximately 30 seconds.

9. Within seven minutes, inflate the tire to

between 22—44 psi (1.8—3.0 bar).

Switch off the compressor briefly to get a

clear reading from the pressure gauge.

09 Wheels and tires

318

Option/accessory, for more information, see Introduction.

The compressor should not be used for

more than 10 minutes at a time to avoid

overheating.

WARNING

If the pressure remains below 22 psi

(1.8 bar) after approximately seven

minutes, turn off the compressor. In this

case, the hole is too large to be sealed and

the vehicle should not be driven.

10. Switch off the compressor and discon-

nect the electrical wire from the 12-volt

socket.

11. Unscrew the hose from the tire’s inflation

valve and reinstall the valve cap.

the valve cap to help avoid damage to

the valve from dirt, gravel, etc.

•

Use plastic valve caps only. Metal caps

could corrode and become difficult to

remove.

12. Immediately drive the vehicle for approxi-

mately 2 miles (3 km) at a maximum

speed of 50 mph (80 km/h) to distribute

the sealing compound in the tire.

If your vehicle is equipped with the Tire

Pressure Monitoring System (TPMS), the

use of the sealing compound may lead to

incorrect tire pressure readings or in rare

cases, damage to the tire pressure sensor.

Use the tire sealing system to check and

adjust the damaged tire's inflation pres-

sure.

•

Safely stow the tire sealing system in a

convenient place as it will soon be

used again to check the tire’s inflation

pressure.

•

The empty bottle of sealing compound

cannot be removed from the bottle

holder. Consult a trained and qualified

Volvo service technician to have the

bottle removed and properly disposed

of.

WARNING

If heavy vibrations, unsteady steering

behavior, or noises should occur while

driving, reduce speed and park the vehicle

in a safe place. Recheck the tire for

bumps, cracks, or other visible damage,

and recheck its inflation pressure. If the

pressure is below 19 psi (1.3 bar), do not

continue driving. Have the vehicle towed

to a trained and qualified Volvo service

technician.

Tire sealing system – checking

inflation pressure

The tire sealing system can also be used to

check the tires' inflation pressure.

Stage 2: Checking inflation pressure
1. Connect the tire sealing system as

described in stage 1, see Tire sealing

2. Refer to the inflation pressure table in this

chapter for the correct inflation pressure.

If the tire needs to be inflated, start the

tire sealing system’s compressor. If nec-

essary, release air from the tire by turning

the air release knob counterclockwise.

The compressor should not be used for

more than 10 minutes at a time to avoid

overheating.

WARNING

If you interrupt your trip for more than 1

hour, check the inflation pressure in the

damaged tire again before continuing.

Tire sealing system* – inflating tires

The tire sealing system can be used to inflate

the tires.

To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.

Ensure that the on/off switch is in position
0 (the 0 side of the switch should be

pressed down).

3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s

inflation valve and screw the hose con-

nector onto the valve as tightly as possi-

ble by hand.

5. Connect the electrical wire to the nearest

12-volt socket in the vehicle.

6. Start the vehicle’s engine.

WARNING

•

The vehicle’s engine should be running

when the tire sealing system is used to

avoid battery drain. Therefore, be sure

the vehicle is parked in a well ventilated

place, or outdoors, before using the

system. The parking brake should be

securely applied and the gear selector

should be in the P (park) position.

•

Children should never be left unatten-

ded in the vehicle when the engine is

running.

7. Check the tire’s inflation pressure on the

gauge. Switch off the compressor briefly

to get a clear reading from the pressure

gauge.

8. Refer to the tire inflation table in this

chapter for the correct inflation pressure.

If the tire needs to be inflated, start the

tire sealing system’s compressor (press

the on/off switch to position I). If neces-

sary, release air from the tire by turning

the air release knob counterclockwise.

The compressor should not be used for

more than 10 minutes at a time to avoid

overheating.

9. Turn off the compressor (press the on/off

switch to position 0) when the correct

inflation pressure has been reached.

10. Unscrew the hose from the tire’s inflation

valve and reinstall the valve cap.
