therefore strongly recommended to observe
regular oil changes using an approved engine
oil with the appropriate SAE classification. Brake fluid
G
WARNING
Ove raperiod of time, the brake fluid absorbs
moisture from the air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake flu-
ids can be obtained from any Mercedes-Benz
Service Centre or on the Internet at
http://bevo.mercedes-benz.com
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Coolant
Important safety notes The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R
anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. The
engine could otherwise be damaged.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com .You can
also consult a Mercedes-Benz Service
Centre.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
If antifreeze/corrosion inhibitor is present in
the correc tconcentration, the boiling point of
the coolant during operation will be around
130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. This will protec tthe engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to -45 †); otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor- Service products and capacities

WARNING
Only have a trailer tow hitch retrofitted at a
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use aMercedes-Benz
Service Centre for this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop.
! If you have a trailer tow hitch retrofitted,
changes to the cooling system may be nec-
essary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage point sonthe chas-
sis frame. Anchorage points for the trailer tow hitch (exam-

24-GHz radar sensor system (country overview)
The 24 GHz radar sensor system requires separate approval for each country. When you are
driving in a country in which the radar sensor system is not approved, you must deactivate
the system using the on-board computer (Y page 242). The current country overview can be
obtained from a Mercedes-Benz Service Centre.
Vehicles with anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities.
