the coolant system and reduce the engine's
service life.
The coolant is a mixture of water and anti-
freeze and corrosion inhibitor. It performs the
following tasks:
R Anti-corrosion protection
R Antifreeze protection
R Raises the boiling point
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze/corrosion protection. Coolant must
remain in the engine cooling system all year
round to ensure anti-corrosion protection and
a higher boiling point, even in countries with
high outside temperatures.
Check the antifreeze/corrosion inhibitor con-
centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
R be at least
50%. This way, the engine cooling
system is protected against freezing down
to approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Otherwise, heat will not
be dissipated as effectively.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the require-
ments in the Mercedes-Benz Specifications for
Service Products Sheet Number 325.
More information can be obtained at any quali-
fied specialist workshop.

Important safety notes The climate control system of your vehicle is
filled with the refrigerant R ‑134a.
The warning label for the refrigerant being
used can be found on the radiator cross mem-
ber.
! Only the refrigerant R‑134a and the PAG
oil approved by Mercedes-Benz may be
used. The approved PAG oil may not be
mixed with any other PAG oil that is not
approved for R-134a refrigerant. Otherwise,
the climate control system may be dam-
aged.
Maintenance work such as adding refrigerant
or replacing components may only be carried
out by a qualified specialist workshop. All
applicable regulations thereto and the SAE
standard J639 must be adhered to.
All work on the climate control system should
always be carried out at qualified specialist
workshop.

WARNING
Windshield washer concentrate is highly
flammable. If windshield washer concentrate
gets onto hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure that windshield washer concen-
trate is not spilled in the vicinity of the filler
neck.
! Only use washer fluid which is suitable for
lamp lenses, e.g. MB SummerFit or MB Win-
terFit. Unsuitable washer fluid may damage
the lamp lenses of the headlamps.
When handling washer fluid, observe the
important safety notes on service products
(Y page

305).
Mixing ratio Add windshield washer concentrate to the
washer fluid all year round. Adapt the mixing
ratio to the ambient temperature. At temperatures above freezing:
X Fill up the washer fluid reservoir with a mix-
ture of water and windshield washer con-
centrate, e.g. Summerwash to prevent
smearing.
At temperatures below freezing:
X Fill up the washer fluid reservoir with a mix-
ture of water and windshield washer con-
centrate, e.g. Winterwash if there is a dan-
ger of frost.
This prevents washer fluid from freezing on
the windshield.

) Cargo tie-down points and carrier
systems
Cargo tie-down points General notes
! Observe the information on the maximum
loading capacity of the individual cargo tie-
down points.
If you use several cargo tie-down points to
secure a load, you must always take the
maximum loading capacity of the weakest
cargo tie-down point into account. Vehicle data
313
Technical data Z

If you brake hard, for example, the forces
acting could be up to several times the
weight force of the load. Always use multi-
ple cargo tie-down points in order to distrib-
ute the force absorption. Load the ancho-
rages evenly.
You will find additional information about
cargo tie-down points and cargo tie-down rings
in the "Securing loads" section
(Y page 244).

down rings is: Cargo tie-down

(1 m) Maximum roof load G
WARNING
If you use openings in the bodywork or
detachable parts as steps, you could:
R slip and/or fall
R damage the vehicle and cause yourself to
fall.
There is a risk of injury.
Always use secure climbing aids, e.g. a suit-
able ladder.
! Do not use the lower sliding door guide
(carriage) as a step. Otherwise, you could
damage the paneling and/or the sliding
door mechanism. G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the usual driving
characteristics, as well as steering and brak-
ing, change. The vehicle tilts more severely
when cornering and may react more slug-
gishly to steering input.
If you exceed the maximum roof load, the
driving characteristics, as well as the steer-
ing and braking, will be greatly impaired.
There is a risk of an accident.
Adjust your driving style and never exceed
the maximum roof load.
! The weight of any load carried on the roof,
including the roof carrier, must not exceed
the maximum permissible roof load.
The roof carrier supports must be mounted
at equal distances.
Install rail carriers in front of and behind the
middle prop.
! For safety reasons, only use roof carriers
that have been tested and approved for
Mercedes-Benz. This will help avoid damage. Maximum roof load
330 lbs (150 kg)
with at least three
pairs of support
points
The data is valid for a load distributed evenly
over the entire roof area. 314
Vehicle data
Technical data

Reduce the load on shorter roof carriers pro-
portionately. The maximum load per pair of
roof carrier supports is
110 lbs (50 kg). The
maximum load of a rail carrier bar is 220 lbs
(100 kg).
Loading guidelines and other information con-
cerning load distribution and load securing can
be found in the "Transporting" section
(Y page 242). Trailer tow hitch
General notes Mercedes-Benz recommends having a trailer
tow hitch retrofitted at an authorized
Mercedes-Benz Van Dealer.
Use only a trailer tow hitch that has been tes-
ted and approved specially for your vehicle by
the distributor named on the inside of the
front cover. Only use a ball coupling for your
Metris trailer tow hitch if it has been approved
for your vehicle. You can also find information
on the permitted dimensions of the ball cou-
pling on the identification plate of the trailer
tow hitch.
You can obtain advice from a qualified special-
ist workshop. Also observe the information on
towing a trailer in the "Driving and parking"
section (Y page

168).
Trailer loads Make sure that you adhere to the local legal
requirements for trailer loads.
The permissible weights and loads which can-
not be exceeded can also be found:
R in your vehicle documents and
R on the identification plates of the trailer
hitch, the trailer and the vehicle
(Y page

You will find the basic values approved by the
manufacturer in the following table. If the val-
ues differ, the lowest value applies.
Make sure that you adhere to the weight
restrictions by having the weight checked on a
calibrated weighbridge. Permissible gross
