ence the following:

To ensure that they are displayed correctly, the

tire sizes must be stored in the system and must

have been set for the mounted tires.

▷ The service life of the tires.

▷ Driving safety.

The current tire inflation pressure value is lo‐

cated on each tire.

▷ Driving comfort.

▷ Fuel consumption.

Checking the tire pressure

General information

Tires heat up while driving. The tire pressure in‐

creases with the tire temperature.

Safety information

Warning

A tire with too little or no tire inflation pressure

may heat up significantly and sustain damage.

This will have a negative impact on aspects of

handling, such as steering and braking re‐

sponse. There is a risk of accident. Regularly

check the tire inflation pressure, and correct it

as needed, for instance twice a month and be‐

fore a long trip.

Tires have a natural, consistent tire pressure

loss.

The displays of inflation devices may under-read

by up to 0.1 bar/2 psi.

The corrected tire inflation pressures are applied

automatically. Make sure that the correct tire set‐

tings have been made.

Checking using tire inflation

pressure specifications in the tire

inflation pressure table

With tires that cannot be found in the tire pres‐

sure values on the Control Display, reset the Tire

Pressure Monitor TPM.

1. Determine the intended tire inflation pressure

levels for the mounted tires.

2. Check the tire inflation pressure in all four

tires, using a pressure gage, for example.

Tire inflation pressures up to

100 mph/160 km/h

For speeds of up to 100 mph/160 km/h and for

optimum driving comfort, note the pressure val‐

ues in the tire inflation pressure table and adjust

as necessary.

3. Correct the tire inflation pressure if the actual

tire inflation pressure deviates from the in‐

tended tire inflation pressure.

4. Check whether all valve caps are screwed

onto the tire valves.

The tire inflation pressure specifications in the

tire inflation pressure table only relate to cold

tires or tires at the same temperature as the am‐

bient temperature.

Only check the tire inflation pressure levels when

the tires are cold, i.e.:

▷ A driving distance of max. 1.25 miles/2 km

has not been exceeded.

▷ If the vehicle has not moved again for at least

2 hours after a trip.

These pressure values can also be found on the

tire pressure label on the driver's door pillar.

The relative performance of tires depends upon

the actual conditions of their use, however, and

may depart significantly from the norm due to

variations in driving habits, service practices and

differences in road characteristics and climate.

bination, can cause heat buildup and possible

tire failure.

M+S

Winter and all-season tires with better cold

weather performance than summer tires.

Traction

The traction grades, from highest to lowest, are

AA, A, B, and C.

Tire tread

Summer tires

Do not drive with a tire tread depth of less than

0.12 in/3 mm, otherwise there is an increased

risk of aquaplaning.

Those grades represent the tire's ability to stop

on wet pavement as measured under controlled

conditions on specified government test surfa‐

ces of asphalt and concrete. A tire marked C may

have poor traction performance.

The traction grade assigned to this tire is based

on straight-ahead braking traction tests, and

does not include acceleration, cornering, hydro‐

planing, or peak traction characteristics.

Winter tires

Do not drive with a tire tread of less than

0.16 in/4 mm, as such tires are less suitable for

winter operation.

Temperature

Minimum tread depth

The temperature grades are A, the highest, B,

and C, representing the tire's resistance to the

generation of heat and its ability to dissipate heat

when tested under controlled conditions on a

specified indoor laboratory test wheel. Sustained

high temperature can cause the material of the

tire to degenerate and reduce tire life, and exces‐

sive temperature can lead to sudden tire failure.

The grade C corresponds to a level of perform‐

ance which all passenger car tires must meet un‐

der the Federal Motor Vehicle Safety Standard

No. 109. Grades Band A represent higher levels

of performance on the laboratory test wheel than

the minimum required by law.

Wear indicators are distributed around the tire

circumference. These wear indicators have the

legally required minimum height of

0.063 in/1.6 mm.

The positions of the wear indicators are marked

on the tire sidewall with TWI, Tread Wear Indica‐

tor.

Warning

The temperature grade for this tire is estab‐

lished for a tire that is properly inflated and not

overloaded. Excessive speed, underinflation, or

excessive loading, either separately or in com‐

ported as needed. Do not repair damaged tires,

but have them replaced.

Tire damage

General information

Inspect your tires regularly for damage, foreign

objects lodged in the tread, and tread wear.

Warning

Tires can become damaged by driving over ob‐

stacles, e.g., curbs or road damage, at high

speed. Larger wheels have a smaller tire cross-

section. The smaller the tire cross-section, the

higher the risk of tire damage. There may be a

risk of accident and risk of damage to property.

If possible, avoid driving over objects or road

conditions that may damage tires, or drive over

them slowly and carefully.

Driving over rough or damaged road surfaces, as

well as debris, curbs and other obstacles can

cause serious damage to wheels, tires and sus‐

pension parts. This is more likely to occur with

low-profile tires, which provide less cushioning

between the wheel and the road. Be careful to

avoid road hazards and reduce your speed, es‐

pecially if your vehicle is equipped with low-pro‐

file tires.

Indications of tire damage or other vehicle mal‐

functions:

Changing wheels and tires

▷ Unusual vibrations.

▷ Unusual tire or running noises.

Mounting and wheel balancing

Have mounting and wheel balancing carried out

by a dealer’s service center or another qualified

service center or repair shop.

▷ Unusual handling such as a strong tendency

to pull to the left or right.

Damage can be caused by the following situa‐

tions, for instance:

▷ Driving over curbs.

▷ Road damage.

Approved wheels and tires

General information

The following properties are recommended and

approved by the manufacturer of the vehicle for

the approved wheels and tires per vehicle type

and special equipment:

▷ Tire pressure too low.

▷ Vehicle overloading.

▷ Incorrect tire storage.

Safety information

▷ Wheel and tire combinations.

▷ Rim designs.

Warning

▷ Tire sizes.

Damaged tires can lose tire inflation pressure,

which can lead to loss of vehicle control. There

is a risk of accident. If tire damage is suspected

while driving, immediately reduce speed and

stop. Have wheels and tires checked. For this

purpose, drive carefully to the nearest dealer’s

service center or another qualified service cen‐

ter or repair shop. Have vehicle towed or trans‐

▷ Tire brands.

You can ask a manufacturer service center or an‐

other qualified service center or repair shop

about the approved wheels and tires for the vehi‐

cle and the special equipment.

MOBILITY

Safety information

Recommended tire brands

Warning

Wheels and tires which are not suitable for your

vehicle can damage parts of the vehicle, for in‐

stance due to contact with the body due to tol‐

erances despite the same official size rating.

There is a risk of an accident. The manufac‐

turer of your vehicle strongly suggests that you

use wheels and tires that have been recom‐

mended by the vehicle manufacturer for your

vehicle type.

For each tire size, the manufacturer of the vehi‐

cle recommends certain tire brands. The tire

brands can be identified by a star on the tire

sidewall.

Warning

Mounted steel wheels can cause technical

problems, for instance unexpected loosening of

the lug bolts and damage to the brake discs.

There is a risk of accident. Do not mount steel

wheels.

New tires

Tire traction is not optimal due to production-re‐

lated circumstances when tires are brand-new.

Drive conservatively for the first

200 miles/300 km.

Retreaded tires

Warning

Incorrect wheel/tire combinations will impair the

vehicle's handling characteristics and a variety

of system functions, such as the Antilock Brak‐

ing System (ABS) or Dynamic Stability Control.

There is a risk of accident. To maintain good

handling and vehicle response, use only tires

with a single tread configuration from a single

manufacturer. The manufacturer of the vehicle

recommends that you use wheels and tires that

have been recommended by the vehicle manu‐

facturer for your vehicle type. Following tire

damage, have the original wheel/tire combina‐

tion remounted on the vehicle as soon as pos‐

sible.

Warning

Retreaded tires can have different tire casing

structures. With advanced age the service life

can be limited. There is a risk of an accident.

The manufacturer of your vehicle does not rec‐

ommend the use of retreaded tires.

The manufacturer of the vehicle does not rec‐

ommend the use of retreaded tires.

Winter tires

General information

Winter tires are recommended for operating on

winter roads.

Although so-called all-season tires with M+S

identification provide better winter traction than

summer tires, they usually do not provide the

same level of performance as winter tires.

325

Wheels and tires

MOBILITY

Maximum speed of winter tires

Repairing a flat tire

If the maximum speed of the vehicle is higher

than the permissible speed for the winter tires,

then attach a label showing the permissible maxi‐

mum speed in the field of vision. The label is

available from a dealer's service center or an‐

other qualified service center or repair shop.

Safety measures

▷ Park the vehicle as far away as possible from

passing traffic and on solid ground.

▷ Turn on the hazard warning system.

With winter tires mounted, observe and do not

exceed the permissible maximum speed.

▷ Secure the vehicle against rolling away by

setting the parking brake.

▷ Turn the steering wheel until the front wheels

are in the straight-ahead position and engage

the steering wheel lock.

Rotating wheels between axles

▷ Have all vehicle occupants get out of the ve‐

hicle and ensure that they remain outside the

hazardous area in a safe place, such as be‐

hind a guardrail.

Warning

Rotating tires between the axles on vehicles

with different tire sizes or rim sizes on the front

and rear axles can cause damage to the tires

and the vehicle. There is a risk of accident. Do

not rotate the tires between the axles on vehi‐

cles with different tire sizes or rim sizes on the

front and rear axles.

▷ If necessary, set up a warning triangle at an

appropriate distance.

Sport tires

Storing tires

MOBILITY

Storage

Tire pressure

If the sport tires are not used for a long period of

time, we recommend removing the wheels from

the vehicle and lowering the tire inflation pres‐

sure to half the level specified by the manufac‐

turer.

General information

Check the tire inflation pressure regularly and

correct it if necessary, taking the regulations for

use on the road or a racetrack into account.

Store wheels or sport tires in a clean, dry, and

dark place at temperatures above 32 ℉/0 ℃.

Tire pressure specifications

The tire inflation pressure table contains all tire

inflation pressure specifications for the specified

tire sizes at the ambient temperature. The tire in‐

flation pressure values apply to tire sizes ap‐

proved by the manufacturer of the vehicle for the

vehicle type.

Use on the road

The sport tires meet the legal regulations for use

on public roads.

After being used on a racetrack, the sport tires

may no longer be suitable for road use. There‐

fore, after they have been used on a racetrack,

check the sport tires against the legal regulations

for use on public roads, for instance the mini‐

mum tread depth.

To identify the correct tire inflation pressure,

please note the following:

▷ Tire sizes of your vehicle.

▷ Maximum speed for driving.

Use on a racetrack

General information

Use on a racetrack

The tires heat up while driving. The tire pressure

increases with the tire temperature.

Inspect the sport tires for damage, foreign ob‐

jects lodged in the tread, and tread wear every

time before using them on a racetrack.

After a period of intensive driving, correct the tire

inflation pressure in the heated tires to the tire in‐

flation pressure values specified by the vehicle

manufacturer.

Bring the sport tires to the correct temperature

for use on a racetrack. To do this, drive a few cir‐

cuits with an appropriate driving style.

After they have been used on a racetrack, allow

the tires to cool down for at least 2 hours. Cor‐

rect the tire inflation pressure of the cold tires to

the tire inflation pressure values specified by the

vehicle manufacturer.

Intensive use

After an extended period of intensive driving on a

racetrack and driving over curbs or leaving the

roadway, the sport tires can become damaged.

After correcting the tire inflation pressure, carry

out a reset of the Tire Pressure Monitor TPM.

Inspect the sport tires for damage, foreign ob‐

jects lodged in the tread, and tread wear. The

wheel must be removed in order to inspect the

outside and inside of the sport tires. Have the

sport tires checked by a dealer’s service center

or another qualified service center or repair shop.

hicle to ensure that the replacement or alternate

tires and wheels allow the TPMS to continue to

function properly.

Declaration according to NHTSA/

FMVSS 138 Tire Pressure

Monitoring System

Each tire, including the spare (if provided) should

be checked monthly when cold and inflated to

the inflation pressure recommended by the vehi‐

cle manufacturer on the vehicle placard or tire in‐

flation pressure label. (If your vehicle has tires of

a different size than the size indicated on the ve‐

hicle placard or tire inflation pressure label, you

should determine the proper tire inflation pres‐

sure for those tires.) As an added safety feature,

your vehicle has been equipped with a tire pres‐

sure monitoring system (TPMS) that illuminates

a low tire pressure telltale when one or more of

your tires is significantly under-inflated. Accord‐

ingly, when the low tire pressure telltale illumi‐

nates, 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 effi‐

ciency and tire tread life, and may affect the vehi‐

cle's handling and stopping ability. Please note

that the TPMS is not a substitute for proper tire

maintenance, and it is the driver's responsibility

to maintain correct tire pressure, even if under-

inflation has not reached the level to trigger illu‐

mination of the TPMS 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 TPMS

malfunction indicator is combined with the low

tire pressure telltale. When the system detects a

malfunction, the telltale will flash for approxi‐

mately one minute and then remain continuously

illuminated. This sequence will continue upon

subsequent vehicle start-ups as long as the mal‐

function exists. When the malfunction indicator is

illuminated, the system may not be able to de‐

tect or signal low tire pressure as intended.

TPMS malfunctions may occur for a variety of

reasons, including the installation of replacement

or alternate tires or wheels on the vehicle that

prevent the TPMS from functioning properly. Al‐

ways check the TPMS malfunction telltale after

Flat Tire Monitor FTM

Principle

The Flat Tire display detects a tire pressure loss

while driving and issues a warning if the tire pres‐

sure has dropped.

General information

The system detects tire pressure loss on the ba‐

sis of rotation speed differences between the in‐

dividual wheels while driving.

In the event of a tire pressure loss, the diameter

and therefore the rotational speed of the corre‐

sponding wheel changes. The difference will be

detected and reported as a flat tire.

The system does not measure the actual infla‐

tion pressure in the tires.

Functional requirements

The following conditions must be met for the

system; otherwise, reliable message of a tire

pressure loss is not assured:

▷ After a tire or wheel replacement, an initializa‐

tion was performed with the correct tire infla‐

tion pressure.

▷ After the tire pressure was adjusted to a new

value, an initialization was performed.
