WARNING
Even if they have not been used, old tyres can suddenly lose pressure or burst, especially at high

km in order to prevent accidents and serious injury.
WARNING
Wheels must have the necessary clearance. If the wheels do not have the necessary clearance, the
tyre could rub on parts of the running gear, vehicle body and the brake lines. This can lead to a fault
in the brake system and to tread separation and thus to a tyre bursting.

Wheel imbalance may develop when the vehicle is driven; you will notice this by nervous steering
response. Unbalanced wheels will affect the level of tyre wear. In this case, the wheels should be
balanced again.
Incorrect wheel alignment impairs driving safety and increases tyre wear. The running gear should
be checked by a qualified workshop if tyres show excessive wear.
WARNING
If you notice unusual vibration or the car pulling to one side while the vehicle is in motion, this may
indicate that one of the tyres is damaged.
Check the tyres and wheel rims for damage.

The tyre lettering is located on both sides. Certain labels may only be found on one side of the tyre,
e.g. tyre identification number and manufacturing date.
Any additional numbers and letters are internal codes used by the tyre manufacturer or country-
specific identifiers.
Low-profile tyres
Low-profile tyres have a wider tread surface, larger rim diameter and lower side walls than
conventional wheel/tyre combinations ⇒ . Low-profile tyres can improve the vehicle's handling
and precision. They may however result in a less comfortable ride on poor road surfaces and tracks.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with directional tread
pattern. The direction of rotation must be observed in all cases. This guarantees the best possible
running characteristics.
If, however, the tyre is fitted in the opposite direction to the tread pattern, you must take more care
when driving as the tyre is now no longer being used according to its designation. The tyre must be
replaced as quickly as possible or be fitted with the tread in the correct direction.
Asymmetrical tyres
Asymmetrical tyres take into account the differing behaviour of the inner and outer areas of the
tread pattern. The sidewalls of asymmetrical tyres are marked to indicate "inside" or "outside".
Make sure that you observe the correct tyre positioning on the wheel rim.

The load index indicates how many kilograms can be loaded onto an individual tyre (tyre load).

Scope of service
The scope of service includes all maintenance work that is necessary in order to keep your vehicle
roadworthy (depending on the operating conditions and vehicle equipment, e.g. engine, gearbox or
service fluids). The maintenance work is divided into inspection work and servicing work. You can
find out what work is required in detail for your vehicle:

Technical data
Notes on technical data
Unless otherwise indicated or separately listed, the technical data apply to the basic model. The
values may differ if additional equipment is fitted, for different model versions and for special
vehicles and in the case of country-specific vehicle specifications. All data in the official vehicle
documents take precedence over these data.
Engine
The vehicle data sticker and the official vehicle documents show which engine is installed in your
vehicle.
Weight
The values for the kerb weight in the following tables apply for the road-ready vehicle with driver
(75 kg), service fluids including fuel tank carrying 90% of its capacity and, where applicable, tools and
spare tyre ⇒ . Additional equipment and retrofitted accessories increase the stated kerb weight
and reduce the maximum permitted load accordingly.
The load comprises the weights of the following:

Performance figures
In certain vehicles with heavy duty running gear, the engine could be governed to provide a
maximum speed of 210 km/h.
The performance figures were measured without equipment which may negatively influence
performance, such as a roof carrier or mudflaps.
Gross combination weight
The specified gross combination weights are applicable only for altitudes up to 1,000 m above sea
level. The maximum gross combination weight must be reduced by approximately 10% for every
further started 1,000 m in altitude.
Notes on the tables
Gearbox abbreviations: MG = manual gearbox, AG = automatic gearbox, DSG® = DSG® dual clutch
gearbox. MG6 = 6-speed manual gearbox.
