Important safety notes i
RACE START is only available in AMG vehi-
cles.
RACE START enables optimal acceleration
from a standing start. The precondition for
this is a suitable high-grip road surface. G
WARNING
RACE START is only available when SPORT
handling mode is activated. SPORT handling
mode will only be able to stabilise the vehicle
to a limited degree if the vehicle starts to skid
or a wheel starts to spin. The vehicle is there-
fore harder to control at the threshold range.
You could lose control of the vehicle and
cause an accident.
RACE START should only be used on closed
off circuits. Always adapt your driving style to
suit the prevailing road and weather condi-
tions. 178

When it leaves the factory, your vehicle's
trailer socket is equipped with a permanent
power supply and a power supply that is
switched on via the ignition lock.
The permanen tpower supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin
10.
! You can connect consumers with a power
rating of up to 240 W to the permanent
power supply and up to 180 W to the power
supply that is switched on via the ignition
lock.
You must not charge a trailer battery using
the power supply.
The trailer's permanent power supply is
switched off in the event of low vehicle supply
voltage and after six hours at the latest.
You can obtain further information about
installing the trailer electrics from a qualified
specialist workshop, e.g. aMercedes-Benz
Service Centre.
X To switch the connected power supply
on or off: turn the key in the ignition lock
to position 2or 0respectively. Bulb failure indicator for LED lamps
i If LED lamps are fitted in the trailer, an
error message may appear in the multi-

Heating menu
Auxiliary heating departure time
This function is only available on vehicles with
auxiliary heating (Y page 128).
In the Heating submenu, you can select a
stored departure time or change a departure
time.
The auxiliary heating timer function calcu-
lates the switch-on time according to the out-
side temperature so that the vehicle is pre-
heated by the departure time. When the
departure time is reached, the auxiliary heat-
ing continues to heat for a further five
minutes and then switches off. The auxiliary
heating adopts the THERMATIC or
THERMOTRONIC temperature setting.
You can switch off the auxiliary heating by
using the remote control or the auxiliary heat-
ing button on the centre console. G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set
the vehicle alight. Choose you rparking spot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at filling stations or when your vehicle
is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
! Operating the auxiliary heating/ventila-
tio nd raws on the vehicl ebattery. Afte ryou
have heated or ventilated the vehicle a maximum of two times, drive for a longer
distance.
i Switch the auxiliary heating on regularly
once a month for about 10 minutes.
