In such circumstances, use atowing bar.
Make sure that the steering is moving freely
befor etowing. G
WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towin geye could detach itself
R the vehicle/traile rcombination coul dover-
turn.
There is arisk of an accident.
When towing or tow-startin ganothe rvehicle,
its weight should not be greater than the per-
missible gross weight of your vehicle. G
WARNING
The vehicle is braked when the HOL Dfunction
or DISTRONIC PLUS is activated. Therefore,
deactivate HOLD and DISTRONIC PLUS if the
vehicle is to be towed.
! Make sure that the electric parking brake
is released. If the electric parking brake is

Additives
! Operatin gthe engin ewith fuel additives
can cause wear in the fuel high-pressure
pump and contaminate the entire fuel sys-
tem. The repair costs are high. This does
not include additives for the removal and
prevention of residue build-up. Petrol must
only be mixed with additives recommended
by Mercedes-Benz .More information about
recommended additives can be obtained
from any Mercedes-Benz Servic eCentre. One of the major problem
swith low-grade
fuel is the creation of carbon deposits during
the process of burnin gfuel. Mercedes-Benz
recommends that you use fuel brands that
have additives.
If you use fuels without these additives for a
longer period of time, there may be abuild-up
of carbon deposits. Thes ewill form especially
on the inlet valves and in the combustion
chamber.
This could lead to engine runnin gproblems,
e.g.:
R longe rengine warm-up phase
R uneven idle
R engine noise
R misfiring
R los so fpower
In areas where petrol with the required addi-
tives is not available, carbon deposits can
build up. In this case, Mercedes-Benz recom-
mends the use of additives that have been
approved for Mercedes-Benz vehicles; see
http:/ /bevo.mer cedes-benz.com.
The quality of the fuel available in some coun-
tries may not be sufficien t.Residue could
build up as aresult. In such cases, and in
consultation with aMercedes-Ben zService
Cent re,the petrol ma ybemixed with the
additive recommended by Mercedes-Benz
(part no. A000989254510). You must
observe the notes and mixin gratios specified
on the container.
Consult aMercedes-Ben zService Cent reto
view alist of approved products. Observe the
instruc tions for use in the product descrip-
tion.
Do not mix other fuel additives with fuel. This
causes unnecessary cost sand could damage
the engi ne. Service products and capacities
