Vehicle tool kit
General notes
Depending on the equipment version of the vehi- cle, the vehicle tool kit is:
Rin the seat base of the left front seat
Rin the rear stowage compartment
Rin the tool holder in the cargo compartment
Apart from some country-specific variants, vehi-
cles without a spare wheel are not equipped
with tire-changing tools. If your vehicle is equip-
ped with tire-changing tools, these are in the
vehicle tool kit. If the vehicle tool kit is stowed in
the driver's seat base, the jack is in a separate
holder in the cargo compartment on the right-
hand side of the vehicle next to the tailgate/rear door (
Ypage 274).
Some tools for changing a wheel are specific to
the vehicle. For more information on which tools are required and approved to perform a wheel
change on your vehicle, consult a qualified spe-
cialist workshop.
Necessary tire-changing tools can include, for
example:
Rjack
Rlug wrench
Rratchet wrench
iThe jack has a maximum weight of 7.5 kg
depending on the vehicle's equipment.
The maximum payload of the jack can be
found on the sticker on the jack itself.
The jack is maintenance-free. In the event of a malfunction, please contact a qualified spe-
cialist workshop.

Maximum tire pressures
:Maximum permitted tire pressure (example)
Never exceed the maximum permissible tire
inflation pressure. When adjusting the tire pres-
sures always observe the recommended tire
pressure for your vehicle (
Ypage 282).
iThe actual values for tires are specific to
each vehicle and may deviate from the values
in the illustration.
Tire valve (snap-in valve)
Important safety notes
GWARNING
Tire valve that are not approved for your vehi-
cle by the distributor named on the inside
cover page may result in a loss of tire pres-
sure. 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.
iFor 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:
XRemove the valve cap of the tire you wish to
check.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it with the
recommended value on the loading informa-
tion table or the tire pressure table
(
Ypage 282).
XIf the tire pressure is too low, increase it to the
recommended value.
XIf 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.
XScrew the valve cap onto the valve.
XRepeat the steps for the other tires.
Tire pressure monitor
General notes
In vehicles with a tire pressure monitor system,
the vehicle's wheels have sensors installed
which monitor the tire pressure in all four tires.
The tire pressure monitor warns you if the pres- sure drops in one or more of the tires. The tire
pressure monitor only functions if the corre-
sponding 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.

Loading the vehicle
Instruction labels for tires and loads
GWARNING
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 accident.
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 themaximum possible load.
(1) Tire and Loading Information placard :is
on the B-pillar on the driver's side. Tire and
Loading Information placard :shows the
permissible number of occupants and the
maximum permissible load of the vehicle. It also contains details of the tire sizes and
corresponding pressures for tires mounted
at the factory.
(2) The vehicle identification plate is on the B-pillar on the driver's side. The vehicle
identification plate informs you of the per-
missible gross weight. It is made up of the
vehicle weight, all vehicle occupants, the
fuel and the cargo. You can also find infor-
mation about the maximum Gross Axle
Weight Rating on the front and rear axle.
The maximum gross axle weight rating is
the maximum weight that can be carried by
one axle (front or rear axle). Do not exceed the permissible gross weight or the maxi-
mum gross axle weight rating for the front
or rear axle.

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".
XStep 1: Locate the statement "The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs." on your vehicle's
Tire and Loading Information placard.
XStep 2: Determine the combined weight of
the driver and passengers that will be travel-
ing in your vehicle.
XStep 3: Subtract the combined weight of the
driver and passengers from XXX kilograms or
XXX lbs.
XStep 4: The resulting figure equals the avail-
able amount of cargo and luggage load capa-
city. For example, if the "XXX" amount equals
1400 lbs and there will be five 150-pound
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400 Ò750 (5 x 150) = 650 lbs).
XStep 5: Determine the combined weight of
luggage and cargo being loaded on the vehi-
cle. For reasons of safety, that weight must
not exceed the available cargo and luggage
cargo capacity calculated in step 4.
XStep 6 (if applicable): If your vehicle is tow-
ing a trailer, load from the trailer will be trans-
ferred to your vehicle. Please consult the Tire
and Loading Information placard, to deter-
mine how this reduces the available cargo and
luggage load capacity of your vehicle.

292Loading the vehicle
Wheels and tires
Vehicle identification plate
Even if you have calculated the total load care-
fully, you should still make sure that the permis-
sible gross weight and the gross axle weight rat-
ing of your vehicle are not exceeded. This data
can be found on the vehicle identification plate
on the B-pillar of your vehicle (
Ypage 305).
Permissible gross vehicle weight: the gross
weight of the vehicle, all occupants, load and
trailer load/noseweight (if applicable) must not
exceed the permissible gross vehicle weight.
Gross axle weight rating: the maximum per-
missible 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 vehicle
weight and maximum gross axle weight rating),
have your loaded vehicle (including driver, occu-
pants, load, and full trailer load if applicable)
weighed on a suitable vehicle weighbridge.
Trailer load/noseweight
The trailer load/noseweight affects the gross
weight of the vehicle. If a trailer is attached, the trailer load/noseweight is included in the load
along with occupants and luggage. The trailer
load/noseweight is usually approximately 10%
of the gross weight of the trailer and its load.

DOT, Tire Identification Number (TIN)
U.S. tire regulations stipulate that every tire
manufacturer or retreader must imprint a TIN in
or on the sidewall of each tire produced.
The TIN is a unique identification number. The
TIN enables the tire manufacturers or retreaders
to inform purchasers of recalls and other safety-
relevant matters. It makes it possible for the
purchaser to easily identify the affected tires.
The TIN is made up of manufacturer identifica-
tion code ;, tire size =, tire type code ?and
manufacturing date A.
DOT (Department of Transportation): tire
symbol :indicates that the tire complies with
the requirements of the U.S. Department of
Transportation.
Manufacturer identification code: manufac-
turer identification code ;provides details on
the tire manufacturer. New tires have a code
with two symbols. Retreaded tires have a code
with four symbols.
Further information about retreaded tires
