RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the vehicle payload. This will
ensure that you do not exceed the permissi-
ble gross vehicle weight rating (GVWR).
Checking the vehicle and trailer weight
RMake sure the weights of the towing vehicle
and the trailer comply with the maximum per-missible values. Have the vehicle/trailer com-
bination weighed on a calibrated weigh-
bridge. The vehicle/trailer combination con-
sists of the towing vehicle including the driver,
passengers and load, as well as the loaded
trailer.
RCheck the maximum permissible gross axle
weight rating of the front and rear axles
(GAWR), the gross trailer weight (GTW), the
gross combination weight rating (GCWR) and
the noseweight of the trailer drawbar (TWR).
Trailer power supply
!
Incorrect wiring of the connector plug could,
under certain circumstances, cause malfunc-
tions in the vehicle's other electronic sys-
tems. We therefore recommend having the
connector plug wired at a qualified specialist
workshop.
!You can connect accessories with a maxi-
mum power consumption of 240 W to the
permanent power supply.
You must not charge a trailer battery using the
power supply.
Your vehicle may be equipped with various elec-
trical installations for trailer towing. Depending
on your trailer, you may need an adapter to con-
nect the electrical system of the trailer with that
of the vehicle.
The trailer socket of your vehicle is equipped at
the factory with a permanent power supply.
The permanent power supply is on the trailer
socket pin assignment 4.
Note that the permanent power supply of the
trailer is not switched off when the on-board voltage is low. This can completely discharge
the starter battery of your vehicle.
Further information on the electrical equipment
currently installed on your vehicle and on instal-
ling trailer electrics can be obtained at any quali-
fied specialist workshop.

!
When recovering a vehicle that has become
stuck, pull it as smoothly and evenly as pos-
sible. Excessive tractive power could damage
the vehicles.
If the drive wheels get trapped on loose or
muddy ground, recover the vehicle with the
utmost care. This is especially the case if the
vehicle is laden.
Never attempt to recover a vehicle with a trailer
attached.
Pull out the vehicle backwards, if possible, using
the tracks it made when it became stuck.

TIN (Tire Identification Number)
A unique identification number which can be
used by a tire manufacturer to identify tires, for
example for a product recall, and thus identify
the purchasers. The TIN is composed of the
manufacturer identification code, tire size, tire
model code and manufacturing date.
Load bearing index
The load bearing index (also load index) is a code
that contains the maximum load bearing capa-
city of a tire.
Traction
Traction is the result of friction between the tires
and the road surface.
TWR (permissible trailer drawbar load)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator
Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of áin (1.6 mm)
has been reached.
Distribution of the vehicle occupants
The distribution of vehicle occupants over des-
ignated seat positions in a vehicle.
Maximum permissible payload weight
Nominal load and goods/luggage load plus
68 kg (150 lb s)multiplied by the number of
seats in the vehicle.
Changing wheels
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes under "Mounting a wheel" (
Ypage 297).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
If your vehicle's tire configuration allows, you
can rotate the tires according to the intervals in
the tire manufacturer's warranty book in your
vehicle documents. If no warranty book is avail-
able, the tires should be rotated every 3,000 to
6,000 miles (5,000 to 10,000 km) or earlier if
tire wear requires. Do not change the direction
of rotation.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is rota-
ted. Avoid oily or greasy cleaning agents.
Check the tire pressure and reactivate the tire
pressure monitor if necessary.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount a spare wheel against the direc-tion of rotation. Observe the time restriction on
use as well as the speed limitation specified on
the spare wheel.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tires
from contact with oil, grease and fuel.

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 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 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 163).
