Important!
When towing the vehicle, please, note the following:
With the automatic central locking activated and the
key in steering lock position 2, the vehicle doors lock if
the left front wheel as well as the right rear wheel are
turning at vehicle speeds of approximately 9 mph
(15 km / h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking.Note:
To signal turns while being towed with hazard warning
f lash er in u se, turn key in steering l ock to position 2 a nd
activate combination switch for left or right turn signal
in usual manner – only the selected turn signal will
operate. Upon canceling the turn signal, the hazard
warning flasher will operate again.
Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in steering lock position 0
or 1). Otherwise, the ESP will immediately be engaged
and will apply the rear wheel brakes. Switch off the
tow-away alarm as well as the ESP, see page 37 and 170.

cluster displayPractical hints Car care Index Traction
The traction grades, from highest to lowest are “AA”,
“A”, “B”, and “C”. 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 performance.Te mp e r a t u r e
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 vehicle tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Wa r n i n g !
The traction grade assigned to this tire is based on
straightahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
Wa r n i n g !
The temperature grade for this tire is established
for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause excessive heat build up
and possible tire failure.
