Important safety notes G
WARNING
Tire valve that are not approved for your
vehicle by the distributor named on the
inside cover page may result in a loss of tire
pressure. This may affect road safety. There
is a risk of an accident.
Only use tire valve that are approved for
your vehicle by the distributor named on the
inside cover page. Always make sure you
have the correct tire valve type for the tires
on your vehicle.
! Do not screw additional weights (check
valves, etc.) onto the tire valves. The elec-
tronic components could thus be damaged.
i For safety reasons, Mercedes-Benz recom-
mends that you only use tire valves that
have been tested for use on your vehicle. Checking the tire pressure manually
In order to determine and adjust the tire pres-
sures, proceed as follows: X Remove the valve cap of the tire you wish to
check.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the loading
information table or the tire pressure table
( Y page
282).
X If the tire pressure is too low, increase it to
the recommended value.
X If the tire pressure is too high, release air by
pressing down the metal pin in the valve.
Use the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat the steps for the other tires. Tire pressure monitor
General notes In vehicles with a tire pressure monitor sys-
tem, the vehicle's wheels have sensors instal-
led which monitor the tire pressure in all four
tires. The tire pressure monitor warns you if
the pressure drops in one or more of the tires.
The tire pressure monitor only functions if the
corresponding sensors are installed on all
wheels.
Tire pressure display (only on vehicles with steer-
ing wheel buttons)
On vehicles with steering-wheel buttons, the
current pressure of the individual wheels in the
display can be shown via the Service menu. Tire pressure

WARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair
the steering and driving characteristics and
lead to brake failure. There is a risk of acci-
dent.
Observe the load rating of the tires. The load
rating must be at least half of the GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load. Example: Tire and Loading Information placard on
the B-pillar, driver's side
Two instruction labels on your vehicle show
the maximum possible load.

Determining the maximum load Individual steps
The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575 in
accordance with the "National Traffic and
Motor Vehicle Safety Act of 1966".
(1) Locate the statement "The combined weight of occupants and cargo should
never exceed XXX kg or XXX lbs." on your
vehicle's placard. on your vehicle's plac-
ard.
(2) Determine the combined weight of the driver and passengers that will be riding in
your vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kg or XXX
lbs.
(4) The resulting figure equals the available amount of cargo and luggage load capa-
city. For example, if the "XXX" amount
equals
1400 lbs and there will be five290

150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is
650 lbs. (1400 Ò 750 (5 x
150) = 650 lbs.).
(5) Determine the combined weight of lug- gage and cargo being loaded on the vehi-
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
The vehicle placard named in Step 1 is the Tire
and loading information placard for your vehi-
cle.
Please note that not all vehicles are approved
for trailer operation. Trailer operation is only
permitted when a trailer hitch is installed
(Y page
315). If in doubt, please consult a
qualified specialist workshop. Example: Steps 1 to 3
The following table shows examples of how to calculate total load and cargo capacities with vary-
ing seating configurations and number and size of occupants. The following examples use a max-

You can find further information under: "Trailer tow hitch"
(Y page 315).Vehicle identification plate
Even if you have calculated the total load care-
fully, you should still make sure that the per-
missible gross weight and the gross axle
weight rating of your vehicle are not exceeded.
This data can be found on the vehicle identifi-
cation plate on the B-pillar of your vehicle
(Y page
304).
Gross Vehicle Weight Rating (GVWR): the
gross weight of the vehicle, all occupants, load
and trailer load/trailer tongue load (if applica-
ble) must not exceed the permissible gross
vehicle weight.
Gross Axle Weight Rating (GAWR): the maxi-
mum permissible load that can be carried by
one axle (front or rear axle).
To ensure that your vehicle does not exceed
the maximum permissible values (gross vehi-
cle weight and maximum gross axle weight rat-
ing), have your loaded vehicle (including driver,
occupants, load, and full trailer load if applica-
ble) weighed on a suitable vehicle weigh-
bridge. Trailer load/trailer tongue load
The trailer load/trailer tongue load affects the
gross weight of the vehicle. If a trailer is
attached, the trailer load/trailer tongue load is
included in the load along with occupants and
luggage. The trailer load/trailer tongue load is
usually approximately
10% of the gross weight
of the trailer and its load. What you should know about wheels

Rotating the wheels
! 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"
(Y page
298).
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
available, 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 rotated. 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
hydroplaning. You will only gain these benefits
if the correct direction of rotation is observed. Changing wheels

Tampering with the engine electron-
ics
! Have work carried out on the engine elec-
tronics and its associated parts, such as
control units, sensors, actuating compo-
nents and fuel lines, only at a qualified spe-
cialist workshop. Vehicle components may
otherwise wear more quickly. This can lead
to the loss of the New Vehicle Limited War-
ranty. Installing electrical or electronic
equipment
You and others can suffer health-related dam-
age through electromagnetic radiation. By
using an exterior antenna, a possible health
risk caused by electromagnetic fields, as dis-
cussed in scientific circles, is taken into
account. Only have the exterior antenna instal-
led by a qualified specialist workshop.
Electrical and electronic devices may have a
detrimental effect on both the comfort and the
operating safety of the vehicle. If equipment of
this kind is installed, its electromagnetic com-
patibility must be checked and verified.
If these devices are linked to functions associ-
ated with resistance to interference, they must
have type approval. This applies to the device
or its interfaces to the vehicle electronics, e.g.
charging brackets.
A telephone or two-way radio to be installed in
the vehicle must be approved. You can obtain
further information from any Mercedes-Benz
Commercial Van Center. For operation of mobile phones and two-way
radios, Mercedes-Benz recommends connec-
tion to an approved exterior antenna. This is
the only way to ensure optimum reception
quality inside the vehicle and to minimize
mutual interference between the vehicle elec-
tronics, mobile phones and two-way radios.
