Safety information

Checking the tire pressure

Warning

General information

The tires heat up while driving. The tire pres-

sure increases with the tire temperature.

A tire with too little or no tire inflation pres-

sure may heat up significantly and sustain

damage. This will have a negative impact

on aspects of handling such as steering and

braking response. There is a risk of accident,

injury, and property damage. 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.

Checking via tire inflation pressure

If equipped with a flat tire monitor, reinitialize

the flat tire monitor.

4. Make sure that all valve caps are screwed

onto the tire valves.

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, follow the tire infla-

tion pressure specifications in the tire pressure

table and adjust as necessary.

The tire inflation pressure specifications in the

tire inflation pressure table only relate to cold

tires or tires at the same temperature as the

ambient temperature.

Only check the tire inflation pressure levels

when the tires are cold, i.e.:

▷

A distance traveled of max. 1.25 miles/2 km

has not been exceeded.

▷

If the vehicle has not moved again for at

least two hours after a trip.

If equipped with an emergency wheel: check

the tire pressure of the emergency wheel in the

cargo area regularly and correct if necessary.

The treadwear grade is a comparative rating

based on the wear rate of the tire when tested

under controlled conditions on a specified gov-

ernment test course. E.g., a tire graded 150

would wear one and one-half, 1 g, times as

well on the government course as a tire graded

100. The relative performance of tires depends

upon the actual conditions of their use, how-

ever, and may depart significantly from the

norm due to variations in driving habits, service

practices and differences in road characteris-

tics and climate.

Runflat tires

Runflat tires, refer to page 357, are labeled

with a circular icon containing the letters RSC

marked on the tire sidewall.

Traction

The traction grades, from highest to lowest,

are AA, A, B, and C.

M+S

Those grades represent the tire's ability to

stop on wet pavement as measured under

controlled conditions on specified government

test surfaces of asphalt and concrete. A tire

marked C may have poor traction perform-

ance.

Winter tires, as well as all-season tires with

better winter performance than summer tires,

can be identified by the M+S marking on the

tire side wall.

Tire tread

Safety information

Warning

The traction grade assigned to this tire is

based on straight-ahead braking traction tests,

and does not include acceleration, cornering,

hydroplaning, or peak traction characteristics.

Temperature

If the tire tread depth is too low, driving

safety may be impaired in critical situations

such as aquaplaning or slush on the road.

There is a risk of accident, injury, and prop-

erty damage. The tire tread depth may not

fall below 0.12 in/3 mm for summer tires and

0.16 in/4 mm for winter and all-season tires,

or observe the statutory regulations on mini-

mum 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 excessive temperature can lead to

sudden tire failure. The grade C corresponds

to a level of performance which all passenger

car tires must meet under 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.

Minimum tread depth

Warning

The temperature grade for this tire is estab-

lished for a tire that is properly inflated and

not overloaded. Excessive speed, underinfla-

tion, or excessive loading, either separately

or in combination, can cause heat buildup

and possible tire failure.

The tire manufacturer’s wear indicators are

distributed over the tire circumference. These

indicators have a height of min. 0.06 in/1.6 mm

and serve as an indicator for tire tread wear.

353

Wheels and tires

MOBILITY

The positions of the wear indicators are

marked on the tire sidewall with TWI, Tread

Wear Indicator.

Warning

The wheels, tires and chassis components

can become damaged when driving over

curbs, road damage, or other obstacles.

Larger wheels have a smaller tire cross-sec-

tion. The smaller the tire cross-section, the

higher the risk of tire damage. There is a risk

of accident, injury, and property damage. If

possible, avoid driving over curbs, road dam-

age or other obstacles, or drive over them

slowly and carefully.

Tire damage

General information

Check your tires regularly for damage, foreign

objects lodged in the tread, and tread wear.

Indications of tire damage or another vehicle

malfunction:

▷

Unusual vibrations.

Unusual tire or running noises.

Exchanging wheels and

tires

Unusual vehicle handling such as a strong

tendency to pull to the left or right.

▷

Uneven wear pattern, e.g., increased wear

in the area of the tire shoulder.

Mounting and wheel balancing

Damage can be caused by the following situa-

tions, for instance:

Have the wheel mounted and balanced by an

authorized service center or another qualified

service center or repair shop.

▷

Driving over curbs.

Road damage.

Suitable wheels and tires

Tire pressure too low.

Vehicle overloading.

Incorrect tire storage.

General information

Only certain wheel/tire combinations are suit-

able depending on vehicle and equipment.

The vehicle manufacturer determines wheel/

tire combinations on the basis of the following

criteria:

Safety information

Warning

▷

Tire size, e.g., tire width, aspect ratio.

Wheel size, e.g., rim diameter, offset.

Damaged tires can lose tire inflation pres-

sure, which can lead to loss of vehicle con-

trol. There is a risk of accident, injury, and

property damage. If tire damage is suspected

while driving, immediately reduce speed and

stop. Have wheels and tires checked. To do

so, drive carefully to an authorized service

center or another qualified service center or

repair shop. Have the vehicle towed or trans-

ported as needed. Do not repair damaged

tires, but have them replaced.

For more information on wheel/tire combina-

tions and special equipment, contact an au-

thorized service center or another qualified

service center or repair shop.

are recommended by the manufacturer of the

vehicle for the respective wheel type.

Safety information

Warning

Recommended tire brands

Wheels and tires that are not suitable for

the vehicle can damage parts of the vehicle.

There is a risk of accident, injury, and prop-

erty damage. The vehicle manufacturer rec-

ommends that you use only wheels and tires

that have been recommended for the vehicle

type.

Warning

Mounted steel wheels can cause technical

problems, for instance unexpected loosening

of the lug bolts and damage to the brake

disks. There is a risk of accident, injury,

and property damage. Do not mount steel

wheels.

Tire types are developed for each vehicle and

optimized specifically for the individual require-

ments of that vehicle, e.g.:

▷

Vehicle handling.

Comfort.

Noise characteristics.

Specially developed tires are marked with

a star on the tire sidewall. After replacing

wheels and tires, the vehicle manufacturer rec-

ommends using star-marked tires again. The

vehicle manufacturer recommends that you

use tires of the same make and tread design.

Warning

Wheel/tire combinations that are not suitable

for the vehicle can affect vehicle handling

and a number of system functions, e.g.,the

Antilock Braking System or Dynamic Stability

Control. There is a risk of accident, injury, and

property damage. The manufacturer of the

vehicle recommends that you use wheels and

tires that have been recommended by the

vehicle manufacturer for the vehicle type. Fol-

lowing tire damage, have the original wheel/

tire combination remounted on the vehicle as

soon as possible.

New tires

Tire traction is not optimal due to manufactur-

ing circumstances when tires are brand new.

Drive conservatively for the first

200 miles/300 km.

Retreaded tires

Warning

Unsuitable wheel studs such as single-sec-

tion wheel studs may loosen or come off. The

wheel may come loose while driving. There

is a risk of accident, injury, and property dam-

age. Use only two-section wheel studs that

Retreated tires can have different tire casing

structures. With advanced age the service life

can be limited. There is a risk of accident,

injury, and property damage. The manufac-

355

Wheels and tires

MOBILITY

turer of the vehicle does not recommend the

use of retreaded tires.

As a rule, all-season tires do not perform the

same as winter tires.

Changing runflat tires

Maximum speed

When changing from runflat tires to standard

tires, it must be ensured that the vehicle con-

tains an emergency wheel or tire mobility kit.

For more information, contact an authorized

service center or another qualified service cen-

ter or repair shop.

Safety information

Warning

If the maximum permissible speed of your

mounted tires is exceeded, the tires may be

damaged. There is a risk of accident, injury,

and property damage. Do not exceed the

maximum permissible speed of the tires.

Wheel change between axles

Warning

A wheel change between the axles on vehi-

cles 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, injury, and property damage. Do

not rotate the tires between the axles on ve-

hicles with different tire sizes or rim sizes on

the front and rear axles.

Maximum speed of winter tires

If the maximum speed of the vehicle is higher

than the maximum permissible speed of the

winter tires, the maximum permissible speed

must be indicated with a sign placed in the

field of vision. The info label is available from

an authorized service center or another quali-

fied service center or repair shop.

Different abrasion patterns can occur on the

front and rear axles depending on individual

driving conditions. The tires can be rotated in

pairs between the axles to achieve even abra-

sion. For more information, contact an author-

ized service center or another qualified service

center or repair shop. After changing, check

the tire pressure and correct, if needed.

ponents may come loose. There is a risk of

accident, injury, or property damage. Reduce

your speed and stop. Do not continue driving.

Contact an authorized service center or an-

other qualified service center or repair shop.

Principle

Runflat tires permit continued driving under

limited conditions even in the event of a com-

plete tire pressure loss.

General information

The wheels consist of tires that are self-sup-

porting to a limited degree and may also in-

clude special rims.

Identification

The reinforcement of the sidewall allows the

tire to remain drivable to a limited degree in

the event of a tire pressure loss.

Follow the instructions for continued driving

with a flat tire.

Safety information

Runflat tires are labeled with a circular icon

containing the letters RSC marked on the tire

sidewall.

Warning

The vehicle handles differently when a runflat

tire has insufficient or no tire pressure; for

instance, reduced directional stability when

braking, braking distances are longer and the

self-steering properties will change. There is

a risk of accident, injury, or property damage.

Rear-wheel steering during

operation with snow chains

General information

In order to guarantee free movement of the

wheels when operating with snow chains,

rear-wheel steering must be turned off when

snow chains are mounted.

Sensors in the tire valves measure the tire in-

flation pressure and tire temperature.

Depending on the tires detected or registered,

the system displays the specified nominal

pressures on the control display and compares

them with the current tire pressures.

Rear-wheel steering is switched on again

automatically when the permitted maxi-

mum speed for snow chains is exceeded:

30 mph/50 km/h.

If tires are being used that are not specified

in the tire inflation pressure details on the ve-

hicle such as tires with special approval, the

system needs to be actively reset. The system

will then take over the actual tire inflation pres-

sures as the target pressures.

The setting for equipped snow chains can only

be used below 30 mph/50 km/h.

trailer and a flat tire. If the trailer swings or

snakes, brake immediately and apply neces-

sary steering corrections as carefully as pos-

sible.

Vehicle handling with damaged tires

Vehicles driven with a damaged tire will han-

dle differently, potentially leading to conditions

such as the following:

▷

Greater likelihood of skidding of the vehicle.

Longer braking distances.

Changed self-steering properties.

Modify your driving style. Avoid abrupt steering

or driving over obstacles, for instance curbs or

potholes.

Warning

Vibrations or loud noises while driving can

System limits

Temperature

The tire inflation pressure depends on the

tire's temperature.

Driving or exposure to the sun will increase the

tire temperature, thus increasing the tire infla-

tion pressure.

Maximum speed

You may continue driving with a damaged tire

at speeds up to 50 mph/80 km/h.

Wheels and tires

MOBILITY

The tire inflation pressure is reduced when the

tire temperature falls again.

Declaration according to NHTSA/

FMVSS 138 Tire Pressure Monitoring

System

These circumstances may cause a warning

when temperatures fall very sharply.

Each tire, including the spare (if provided)

should be checked monthly when cold and in-

flated to the inflation pressure recommended

by the vehicle manufacturer on the vehicle

placard or tire inflation pressure label. (If the

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, the vehi-

cle has been equipped with a tire pressure

monitoring system (TPMS) that illuminates a

low tire pressure telltale when one or more

of your tires is significantly under-inflated. Ac-

cordingly, 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 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 illumination of the

TPMS low tire pressure telltale. The vehicle

has also been equipped with a TPMS malfunc-

tion indicator to indicate when the system is

not operating properly. The TPMS malfunction

indicator is combined with the low tire pres-

sure telltale. When the system detects a mal-

function, the telltale will flash for approximately

one minute and then remain continuously il-

luminated. This sequence will continue upon

subsequent vehicle start-ups as long as the

malfunction exists. When the malfunction indi-

cator is illuminated, the system may not be

able to detect 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

Safety information

Warning

The jack is optimized for lifting the vehicle

and for the jacking points on the vehicle only.

There is a risk of injury. Do not lift any other

vehicle or cargo using the jack.

Warning

The jack is only provided for short-term lifting

of the vehicle for wheel changes. Even if all

safety precautions are observed, there is a

risk of the raised vehicle falling if the jack tips

over. There is a risk of injury or danger to life.

When the vehicle is raised with the jack, do

not lie under the vehicle and do not switch on

the drive-ready state.

Warning

When the jack is not inserted into the jacking

point provided for this purpose, the vehicle

may be damaged or the jack may slip when

it is being cranked up. There is a risk of injury

or risk of damage to property. When cranking

up the jack, ensure that it is inserted in the

jacking point next to the wheel well.

Warning

Placing supports, e.g., wooden blocks or sim-

ilar, under the jack may reduce its ability to

bear weight because of the limited height.

The load-carrying capacity of the wooden

blocks may be exceeded and the vehicle may

tip over. There is a risk of injury or danger to

life. Do not place supports under the jack.

Warning

A vehicle that is raised on a jack may fall

off of the jack if lateral forces are exerted

on it. There is a risk of injury and risk of

property damage. While the vehicle is raised,

do not exert lateral effort on the vehicle or

pull abruptly on the vehicle. Have a stuck

wheel removed by an authorized service cen-

ter or another qualified service center or re-

pair shop.

Warning

The jack, issued by the vehicle manufacturer,

is provided in order to perform a wheel

change in the event of a breakdown. The

jack is not designed for frequent use, e.g.,

changing from summer to winter tires. Using

the jack frequently may cause it to become

jammed or damaged. There is a risk of injury

and risk of property damage. Only use the

jack to change an emergency or spare wheel

in the event of a breakdown.

NOTICE

Using an impact wrench to loosen or tighten

the wheel lock bolt can damage the wheel

lock bolt. There is a risk of property damage.

Only use a lug wrench to loosen and tighten

the wheel lock bolt.

Warning

The jack may slip on soft, uneven, or slippery

ground, e.g., snow, ice, tiles, etc. There is a

risk of injury. If possible, change the wheel on

a flat, solid, slip-resistant surface.

Securing the vehicle against rolling

away

Lug bolt lock

Principle

General information

The vehicle manufacturer recommends to ad-

ditionally secure the vehicle against rolling

away when changing a wheel.

The wheel lug bolts have a special coding. The

lug bolts can only be released with the adapter

which matches the coding.

Overview

On a level surface

Depending on vehicle equipment, store the lug

bolt lock adapter as follows:

▷

In the cargo area under the cargo area

floor.

▷

In the cargo area on the left or right side.

In the cargo area behind a side trim panel.

Place chocks or other suitable objects in front

and behind the wheel that is diagonal to the

wheel being changed.

On a slight downhill gradient

▷

Lug lock bolt, arrow 1.

Adapter, arrow 2.

Unscrewing

1. Attach the adapter to the lug lock bolt.

2. Unscrew the lug lock bolt.

3. Remove the adapter after unscrewing the

lug bolt.

If it is necessary to change a wheel on a slight

downhill gradient, place chocks and other suit-

able objects, e.g., rocks, under the wheels of

the front and rear axles, against the direction

that the vehicle will move.

Screwing on

1. Attach the adapter to the lug lock bolt. Turn

the adapter until it fits onto the wheel lock

bolt.

2. Screw on the lug lock bolt. The tightening

torque is 101 lbs ft/140 Nm.

3. Remove the adapter and stow it after

screwing on the lug bolt.

Safety precautions

Jacking up the vehicle

▷

Park the vehicle on solid and non-slip

ground at a safe distance from road traffic.

Warning

▷

Turn on the hazard warning system.

Set the parking brake.

Hands and fingers can be jammed when us-

ing the jack. There is a risk of injury. Comply

with the described hand position and do not

change this position while using the jack.

Turn the steering wheel until the front

wheels are in the straight-ahead position

and engage the steering wheel lock.

1. Hold the vehicle jack with one hand, ar-

row 1, and grasp the jack crank handle or

lever with your other hand, arrow 2.

▷

Engage a gear or move the selector lever to

position P.

As soon as permitted by the traffic flow,

have all vehicle occupants get out and

make sure that they remain outside the

hazardous area such as behind a guardrail.

▷

If necessary, set up the hazard triangle or

hazard warning lights at an appropriate

distance.

Depending on vehicle equipment, remove

the wheel change set and, if necessary, the

emergency wheel from the vehicle.

2. Insert the jack into the rectangular recess of

the jacking point closest to the wheel to be

changed.

Secure the vehicle additionally against roll-

ing away.
