available, you may add the following engine
oils until the next oil change:

Additives
!
Do not use any additives with the engine
oil. This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective outside temperatures and in accordance with
the SAE classification (viscosity). The table
shows you which SAE classifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regular oil changes using an approved engine oil with the
appropriate SAE classification. 474

Trailer tow hitch
Mounting dimensions
! If you have a trailer tow hitch retrofitted,
changes to the engine cooling system may
be necessary, depending on the vehicle
type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chas- sis. The retrofitting of a trailer tow hitch is only
permissible if a towing weight is specified in
your vehicle documents. If this is not the case,
then the vehicle is not approved for the tow-
ing of a trailer.
For more information, please contact a quali-
fied specialist workshop.
Towing a trailer is not possible with all mod-
els. For further information, see (Y page 284). :

Maximum drawbar noseweight
!
Use a drawbar noseweight as close as possible to the maximum permissible noseweight.
Do not use a noseweight of less than 50kg, otherwise the trailer may come loose.
Note that the payload and the rear axle load are reduced by the actual payload.
Towing a trailer is not possible with all models. For further information, see (Y page 284).
The drawbar noseweight is not included in the trailer load. Trailer tow hitch

However, the actual noseweight must not exceed the value given on the trailer tow hitch
identification plate. In addition, a distinction should be made between towing a trailer and
using a carrier system on the ball coupling of the trailer tow hitch.
Note also that the payload and the rear axle load are reduced by the actual noseweight.
You can attach carrier systems, e.g. bicycle racks or load-bearing implements, on the ball
coupling. The maximum noseweight of 75 kg applies when using carrier systems on the ball
coupling. Permissible rear axle load when towing a trailer
