Important safety notes G
WARNING
An incorrectly secured roof carrier, ski rack or
load could become detached from the vehi-
cle. These objects might then be thrown
around and could injure you or others or
cause an accident. Follow the roof carrier/ski
rack manufacturer's installation instructions
and special instructions for use. The roof load raises the vehicle's centre of
gravity, thereby affecting vehicle handling.
You must always observe the maximum roof
load of 100 kg. Always adapt your driving style
to the prevailing road, traffic and weather
conditions and drive with particular care if the
roof is laden.
! Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the vehi-
cle.
Position the load on the roof carrier in such
a way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is fitted

Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. G

i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 – 2 litres.
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
