are used to help in finding malfunctions and
improving quality and are sent to the manufac-
turer where necessary. In addition, the manu-
facturer is subject to product liability. The man-
ufacturer needs technical data from vehicles for
this purpose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com-
fort and infotainment functions yourself as part
of the selected equipment.
These include, for example:
Rmultimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
Raddress book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
Rnavigation destinations that have been
entered
Rdata about using Internet services
These data can be saved locally in the vehicle or
are located on a device that you have connected
to the vehicle. If this data is saved in the vehicle,
you can delete it at any time. These data are sent
to third parties only at your request, particularly
when you use online services in accordance with
the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the piece of equipment in ques-
t

ion, these can include, for example:
Rseat and steering wheel position settings
Rsuspension and climate control settings
Rcustom settings such as interior lighting
If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile
end device to the vehicle. You can control this by
means of the control elements integrated in the vehicle. The smartphone's picture and sound
can be output via the multimedia system. Spe-
cific items of information are also sent to your
smartphone.
Depending on the type of integration, this can
include:
Rgeneral vehicle information
Rposition data
This allows the use of selected smartphone
Apps, such as navigation or music player Apps.
There is no additional interaction between the smartphone and the vehicle, particularly active
access to vehicle data. The type of additional
data processing is determined by the provider of
the App being used. Whether you can configure
settings for it and, if so, which ones, depends on
the App and your smartphone's operating sys-
tem.
Service provider
Wireless network connection
If your vehicle has a wireless network connec-
tion, data can be exchanged between your vehi-
cle and other systems. The wireless network
connection is enabled by either an in-vehicle
transmitter and receiver or your own mobile end
device (e.g. smartphone). Online functions can
be used via this wireless network connection.
These include online services and applications/ Apps provided by the manufacturer or other
providers.
Services provided by the manufacturer
In the case of the manufacturer's online serv-
ices, the manufacturer describes the functions
in a suitable place and the associated informa-
tion subject to data protection legislation. Per-
sonal data can be used in order to provide online
services. Data are exchanged via a secure con-
nection (e.g. using the IT system specially pro-
vided for this purpose by the manufacturer).
Collecting, processing and using personal data
beyond the provision of services is permitted
only on the basis of a statutory permit or decla-
ration of consent.
You can usually activate and deactivate the serv-
ices and functions (some of which are subject to
charge). In many cases, this also applies to the
vehicle's entire data connection. However, this
does not apply in particular to legally prescribed
functions and services such as the "eCall" emer-
gency call system.
Services from third parties
If it is possible to use online services from other
providers, these services are the responsibility
of the provider in question and subject to that
provider's data protection conditions and terms
of use. The manufacturer has no influence over
the content exchanged here.

While driving ,pay attention to vibrations, noises
and unusual handlin gcharacteristics ,e.g. pull-
ing to on eside .This may indicat ethat th e
wheels or tires are damaged. If you suspec tthat
a tire is defective, reduce your spee dimmedi-
ately. Stop th evehicl eas soo nas possible to
chec kth ewheels and tires for damage. Hidden
tire damag ecould also be causing th eunusual

wit hth eoptimized rubber compound ,there is
an increased ris kof hydroplaning and skid-
din gon damp or wet road surfaces. In addi-

Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 5 lbs (2.3 kg). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-volt-
age battery, are not included in the curb weight
and the weight of the accessories.
TIN (Tire Identification Number)
This is a unique identifier which can be used by
a tire manufacturer to identify tires, for example
for a product recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur- er's identity code, tire size, tire type code and
the manufacturing date.
Load bearing index
The load bearing index (also load index) is a code
that contains the maximum load bearing capa-
city of a tire.
Traction
Traction is the result of friction between the tires
and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of áin (1.6 mm)
has been reached.
Occupant distribution
The distribution of occupants in a vehicle at their
designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(150 lbs) multiplied by the number of seats in
the vehicle.
Changing a wheel
Flat tire
The "Breakdown assistance" section
(Ypage 249) contains information and notes on
how to deal with a flat tire.
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes in the "Mounting a wheel" section
(
Ypage 280).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000 km). Depending on tire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is rota- ted. Check the tire pressure and reactivate the
tire pressure monitor if necessary.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.
