Mounting a wheel
Vehicle preparation
XStop the vehicle as far away as possible from
traffic and on a level, firm and non-slip sur-
face.
XIf your vehicle poses a risk to approaching
traffic, switch on the hazard warning lamps.
XApply the parking brake.
XTurn the front wheels to the straight-ahead
position.
XShift the transmission to position P.
XSwitch off the engine.
XPassengers should leave the vehicle. Make
sure that the passengers are not endangered
as they do so.
XMake sure that no one is near the danger area
while the wheel is being changed. Anyone
who is not directly assisting in the wheel
change should, for example, stand behind the
barrier.
XPlace the warning triangle or warning lamp at
a suitable distance.
Observe the legal requirements on the cor-
rect use of the warning triangle or warning
lamp for the country in which you are cur-
rently driving
XSecure the vehicle to prevent it from rolling
away.
Observe the safety notes on parking under
"Driving and parking" (
Ypage 135)
XOn level terrain: place chocks or other suit-
able objects under the front and rear of the
wheel that is diagonally opposite the wheel to
be changed.
XOn slight inclines: place chocks or other
suitable objects under the wheels on the front and rear axles opposite the wheel to be
changed.
XIf included in the vehicle equipment, take the
tire-changing tool kit out of the vehicle tool kit
(
Ypage 272).
Apart from some country-specific variants,
vehicles are not equipped with tire-changing
tools. Some tools for changing a wheel are
specific to the vehicle. Consult a qualified
specialist workshop for more information on
which tools are required to perform a wheel
change on your vehicle.
XIf included in the vehicle equipment, remove
the spare wheel from the spare wheel bracket (
Ypage 303). Observe the safety notes listed
under "Spare wheel" (Ypage 303).
XCarefully remove the hub caps.
XUsing lug wrench :, loosen the wheel bolts
on the wheel to be changed counter-clock-
wise by about one full turn. Do not remove the
wheel bolts.
Raising the vehicle
GWARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
GWARNING
On uphill and downhill slopes, the jack could
tip over with the vehicle raised. There is a risk
of injury.
Do not change wheels on uphill or downhill
gradients. Notify a qualified specialist work-
shop.
!Only position the jack on the jacking points
intended for this purpose. You could other-
wise damage the vehicle.
Observe the following when raising the vehicle:
RTo raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved

nance work under the vehicle.
RAvoid changing the wheel on uphill and down-
hill slopes.
RBefore raising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Never disengage the
parking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
RMake sure that the distance between the
underside of the tires and the ground does not
exceed 1.2 in(3 cm).
RNever place your hands or feet under the
raised vehicle.
RNever lie under the raised vehicle.
RNever start the engine when the vehicle is
raised.
RNever open or close a door or the tailgate/
door when the vehicle is raised.
RMake sure that no persons are present in the
vehicle when the vehicle is raised.

the side support surfaces.
Removing a wheel
!Do not place wheel bolts in sand or on a dirty
surface. The bolt and wheel hub threads could
otherwise be damaged when you screw them
in.
XUnscrew the wheel bolts.
XRemove the wheel.
Mounting a new wheel
GWARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always observe the instructions and safety
notes on "Changing a wheel" (
Ypage 298).

Cargo tie-down points and carrier sys-
tems
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 max-
imum loading capacity of the weakest cargo
tie-down point into account.
If you brake hard, for example, the forces act-
ing could be up to several times the weight
force of the load. Always use multiple cargo
tie-down points in order to distribute the force absorption. Load the anchorages evenly.
You will find additional information about cargo
tie-down points and cargo tie-down rings in the
"Securing loads" section (
Ypage 246).
Cargo tie-down rings
The maximum tensile load of the cargo tie-down
rings is:

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).
