GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight of
the vehicle including fuel, tools, spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight if applicable. The gross
vehicle weight must never exceed the permissi-
ble gross weight (GVWR) specified on the
B-pillar on the driver's side (
Ypage 305).
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permitted gross
weight of the fully laden vehicle (weight of the
vehicle including all accessories, occupants,
fuel, luggage and the drawbar noseweight if
applicable). The permissible gross weight is
specified on the vehicle identification plate on
the B-pillar on the driver's side (
Ypage 305).
Maximum weight of the laden vehicle
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa are the
equivalent of 1 psi. Another tire pressure unit is
bar. 100 kilopascals (kPa) are the equivalent of
1 bar.
Load index
In addition to the load bearing index, a load
index can be stamped onto the sidewall of the
tire. It specifies the load-bearing capacity of the
tire more precisely.
Curb weight
The weight of a vehicle with standard equipment
including the maximum filling capacity of fuel,
oil, and coolant. It also includes the air-condi-
tioning system and optional equipment if these
are installed on the vehicle, but does not include
passengers or luggage.
Maximum tire load
The maximum tire load in kilograms or pounds is
the maximum weight for which a tire is
approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one tire.
Maximum load on one tire
Maximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.
PSI (Pounds per square inch)
Standard unit of measurement for tire pressure.
Aspect ratio
Relationship between tire height and width in
percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's surface.
Tire pressure is specified in pounds per square
inch (psi), in kilopascal (kPa) or in bar. Tire pres-
sure should only be corrected when the tires are
cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
Rif the vehicle has not been driven further than
1 mile (1.6 km)
Tire tread
The part of the tire that comes into contact with
the road.
Tire bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
tire bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, a roof rack or a high-performance bat-
tery, are not included in the curb weight and theweight of the accessories.

Guide/load rails
The maximum tensile load for the cargo tie-
down points on a guide/load rail is:
Cargo tie-down
pointPermissible nomi-nal tensile load
Guide rail786.5 lbf
(350 daN)
Load rails on cargo
compartment floor1124.0 lbf (500 daN)
Load rail on sidewall225.0 lbf
(100 daN)
The values specified apply only to loads placed
on the cargo compartment floor if:
Rthe load is secured to two cargo tie-down
points on the rail and
Rthe distance to the nearest load-securing
point on the same rail is approximately 3 ft
(1 m)
Maximum roof load
GWARNING
If you use openings in the bodywork or
detachable parts as steps, you could:
Rslip and/or fall
Rdamage the vehicle and cause yourself to
fall.
There is a risk of injury.
Always use secure climbing aids, e.g. a suita-
ble ladder.
!Do not use the lower sliding door guide (car-
riage) as a step. Otherwise, you could damage
the paneling and/or the sliding door mecha-
nism.
GWARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character-
istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.
There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
!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, Mercedes-Benz recom-
mends that you only use roof carrier systems
which have been tested and approved for
Mercedes-Benz vehicles. This will help to
avoid damage.
Maximum roof load330 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.
Reduce the load on shorter roof carriers pro-
portionately. The maximum load per pair of roof
carrier supports is 110 lbs (50 kg). The maxi-
mum 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
(
Ypage 244).
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 tested
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 coupling on the
identification plate of the trailer tow hitch.
You can obtain advice from a qualified specialist
workshop. Also observe the information on tow-
ing a trailer in the "Driving and parking" section
(
Ypage 165).
