16 Introduction
Operating safety
Proper use of the vehicle
Proper use of the vehicle requires that you
are familiar with the following information
and rules:

the safety precautions in this manual

the “Technical data” section in this
manual

traffic rules and regulations

motor vehicle laws and safety stan-
dards
Warning!G
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because
the vehicle’s electronic components are in-
terconnected, any modifications made may
produce an undesired effect on other sys-
tems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
See an authorized Mercedes-Benz Light
Truck Center for repairs or modifications to
electronic components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore nev-
er turn off the engine while driving.
Warning!G
Heavy blows against the vehicle underbody
or tires / wheels, for example when running
over an obstacle, road debris or a pothole,
may cause serious damage and impair the
operating safety of your vehicle. If you feel a
sudden significant vibration or ride distur-
bance, or you suspect that damage to your
vehicle has occurred, you should turn on
your hazard warning flashers, carefully slow
down, and drive with caution to an area
which is a safe distance from the road.
Inspect the vehicle underbody and
tires / wheels for possible damage. If the ve-
hicle appears unsafe, have it towed to the
nearest authorized Mercedes-Benz Light
Truck Center or other qualified maintenance
or repair facility for further inspection or re-
pairs.
Warning!G
Various warning labels are attached to your
vehicle. These warning labels are intended
to make you and others aware of various
risks. You should not remove any of these
warning labels unless explicitly instructed to
do so by information on the label itself. Re-
moval of any of these labels may cause you
and others to be unaware of certain risks
which may result in an accident and / or per-
sonal injury.

R 350 (R 320 CDI similar)
1Filler cap
R 500 (R 63 AMG similar)
1Filler cap
iAll models (except R 63 AMG):
The filling quantity between the upper and
lower marks on the oil dipstick is approximately
2.1 US qt (2.0 l).
R 63 AMG:
The filling quantity between the upper and
lower marks on the oil dipstick is approximately
1.6 US qt (1.5 l).
!Only use approved engine oils and oil filters
required for vehicles with Maintenance System
(U.S. vehicles) or FSS PLUS (Canada vehicles).
For a listing of approved engine oils and oil
filters, refer to the Factory Approved Service
Products pamphlet in your vehicle literature port-
folio, or contact an authorized Mercedes-Benz
Light Truck Center.
Using engine oils and oil filters of specification
other than those expressly required for the
Maintenance System (U.S. vehicles) or
FSS PLUS (Canada vehicles), or changing of oil
and oil filter at change intervals longer than
those called for by the Maintenance System
(U.S. vehicles) or FSS PLUS (Canada vehicles)
will result in engine or emission control system
damage not covered by the Mercedes-Benz
Limited Warranty.

370 Operation
Engine compartment
Unscrew filler cap1 from filler neck.
Add engine oil as required. Be careful
not to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
Screw filler cap1 back on filler neck.
For more information on engine oil, see
“Technical data” section (
page 538) and
(
page 540).
Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Light
Truck Center check the automatic trans-
mission.Coolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze. To check
the coolant level, the vehicle must be
parked on level ground.
!Excess oil must be siphoned or drained off.
It could cause damage to the engine or
emission control system not covered by the
Mercedes-Benz Limited Warranty.Warning!G
In order to avoid any possibly serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.

Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.

380 Operation
Tires and wheels
Certification label
Even after careful determination of the
combined weight of all occupants, cargo
and the trailer tongue load (if applicable)
(
page 380) as to not exceed the permis-
sible load limit, you must make sure that
your vehicle never exceeds the Gross
Vehicle Weight Rating (GVWR) and the
Gross Axle Weight Rating (GAWR) for
either the front or rear axle. You can obtain
the GVWR and GAWR from the certification
label. The certification label can be found
on the driver’s door B-pillar, see “Technical
data” (
page 526).
Gross Vehicle Weight Rating (GVWR): The
total weight of the vehicle, all occupants,
all cargo, and the trailer tongue load
(
page 380) must never exceed the
GVWR.
Gross Axle Weight Rating (GAWR): The to-
tal allowable weight that can be carried by
a single axle (front or rear). To assure that your vehicle does not
exceed the maximum permissible weight
limits (GVWR and GAWR for front and rear
axle), have the loaded vehicle (including
driver, passengers and all cargo and, if
applicable, trailer fully loaded) weighed on
a suitable commercial scale.
Trailer tongue load
The tongue load of any trailer is an impor-
tant weight to measure because it affects
the load you can carry in your vehicle. If a
trailer is towed, the tongue load must be
added to the weight of all occupants riding
and any cargo you are carrying in the
vehicle. The tongue load typically is
between 10% and 15% of the trailer weight
and everything loaded in it.
Recommended tire inflation pressure
Warning!G
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.

designed for use with the electric air pump. Use
a power outlet (
page 322) for electric air
pump operation.
Warning!G
Air hose 4 and union nut5 can become
hot during inflation. Exercise proper caution
to avoid burning yourself when using the
equipment.
!Do not operate the electric air pump longer
than 8 minutes without interruption. Otherwise it
may overheat.
You may operate the electric air pump again
after it has cooled off.
