Tire pressure table
Tire pressure table inside the fuel filler flap (exam-
ple: Passenger Van)
Tire pressure table inside the fuel filler flap (exam-
ple: Cargo Van)
You will find the recommended tire pressure for
various operating conditions on the inside of
your vehicle's fuel filler flap (
Ypage 135) and
under "Tire pressure table" (Ypage 290).
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid for
that tire size.
Example: Cargo Van vehicle loads
Example: Passenger Van vehicle loads
:
Partially laden vehicle
;Fully laden vehicle
For the Passenger Van, the vehicle loads are
defined in the table as different numbers of pas-
sengers and amounts of luggage. The actual
number of seats may vary – for more informa-
tion, please refer to the vehicle's registration
documents.
The tire pressure value given for partly laden
vehicles are minimum values which offer you
good ride comfort. They are not for towing trail-
ers.
You can also use the tire pressure values for a
fully laden vehicle. These are always permitted
and admissible. However, in a partially laden
vehicle, the ride is not as comfortable and fuel
consumption is only minimally reduced. In addi- tion, wear is greater in the center of the tire
tread.
For towing trailers, the applicable value for the
rear tires is the maximum tire pressure value
stated in the table inside the fuel filler flap.

Therefore, you should only correc ttire pressur e
when th etires are cold.
The tires are cold:
Rif th evehicl ehas been parked for at least
three hour swithout direct sunligh ton th e
tires ,and
Rif th evehicl ehas no tbeen driven further than
1 mile (1. 6km)
Tir etemperature changes depending on th e
ambien ttemperature, driving spee dand tire

(10 †), th etire pressur echa
nges by approx
-
imately 10 kP a(0.1 ba r/1.5psi) . Take this into
account when checking the pressure of warm
tires. Only correct the tire pressure if it is too low
for the current operating conditions. If you
check the tire pressure when the tires are warm,
it results in a higher value than when the tires
are cold. This is normal. Do not under any cir-
cumstances release the air in order to adjust the pressure to the prescribed value for cold tires.
The tire pressure would otherwise be too low.
Observe the recommended tire pressure for
cold tires on the tire pressure table in the fuel
filler flap. Driving with tire pressure that is too high or too
low can:
Rshorten the service life of the tires
Rcause increased tire damage
Rhave a negative effect on handling character-
istics and thus the driving safety (e.g. hydro-
planing)
Underinflated or overinflated tires
Underinflated tires:
GWARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addition, they also suffer from excessive and/or irreg-
ular wear, which can severely impair the brak-
ing properties and the driving characteristics.
There is a risk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires can:
Rfail from being overheated
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on fuel consumption
Overinflated tires
GWARNING
Tires with excessively high pressure can burst
because they are damaged more easily by
road debris, potholes etc. In addition, they
also suffer from irregular wear, which can
severely impair the braking properties and the driving characteristics. There is a risk of an
accident.
Avoid tire pressures that are too high in all the
tires, including the spare wheel.
Overinflated tires can:
Rincrease the braking distance
Radversely affect handling
Rwear excessively and/or unevenly
Radversely affect ride comfort
Rbe more susceptible to damage

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.

For further information on displaying the current
tire pressures, refer to "Checking the tire pres-
sure electronically" (
Ypage 288).
Important safety notes
GWARNING
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tire and Loading Information placard on
the driver's door B-pillar or the tire pressure
label on the inside of the fuel filler flap. If your
vehicle has tires of a different size than the
size indicated on the Tire and Loading Infor-
mation placard or the tire pressure label, you
should determine the proper tire pressure for
those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires
are significantly underinflated. Accordingly,
when the low tire pressure telltale illuminates,
you should stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on a significantly underin-
flated tire causes the tire to overheat and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
USA only:
Your vehicle has al so b
een equipped with a
TPMS malfunction indicator to indicate if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the warning lamp will
flash for approximately a minute and then
remain continuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from func-
tioning properly. Always check the TPMS mal-
function telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function prop-
erly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pressure
suitable for the operating conditions
(
Ypage 282).
Note that the correct tire pressure for the cur-
rent operating conditions must first be pro-
gramed into the tire pressure monitor. If a sub-
stantial pressure loss occurs, the warning
threshold for the warning message is aligned to
the taught-in reference values. Restart the tire
pressure monitor after adjusting the cold tire
pressure (
Ypage 289). The current pressures
are saved as new reference values. This will
ensure that a warning message will only appear
if the tire pressure drops significantly.
The tire pressure monitor does not warn you if a
tire pressure is incorrect. Observe the notes on
the recommend
ed tire pressure (Ypage 282).
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. following pen- etration by a foreign object. In this event, brake
the vehicle until it comes to a standstill. Avoid
sudden steering movements.
The tire pressure monitor has a yellow h
warning lamp in the instrument cluster for indi-
cating pressure loss/malfunctions (USA) or
pressure loss (Canada). Depending on how the
warning lamp flashes or lights up, an underin-
flated tire or a malfunction in the tire pressure
monitor is displayed:
Rif the h warning lamp is lit continuously,
the tire pressure on one or more tires is sig-

nificantly too low. The tire pressure monitor is
not malfunctioning.
RUSA only: if thehwarning lamp flashes for
60 seconds and then remains lit constantly,
the tire pressure monitor is malfunctioning.
The display also shows a message:
Ron vehicles without steering wheel buttons
(Ypage 203)

(Ypage 219)
USA only: if the tire pressure monitor is mal-
functioning, it may be more than ten minutes
before the malfunction is shown. The htire
pressure warning lamp flashes for 60 seconds
and then remains lit. When the malfunction has
been rectified, the htire pressure warning
lamp goes out after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gauge.
The tire pressures shown by the on-board com-
puter refer to those measured at sea level. At
high altitudes, the tire pressure values indicated
by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tire pressures.
If radio transmitting equipment (e.g. wireless
headphones, two-way radios) is operated inside
the vehicle or in the vicinity of the vehicle, this
can interfere wi th th
e operation of the tire pres-
sure monitor.

Vehicles with steering wheel buttons:if the
wheel positions on the vehicle are rotated, the
tire pressures may be displayed for the wrong
positions for a short time. This is rectified after a
few minutes of driving; the tire pressures are
then displayed for the correct positions.
Restarting the tire pressure monitor
General notes
When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamp goes out. The monitor uses the
currently set tire pressures as the reference val-
ues for monitoring. In most cases, the tire pres-
sure monitor will automatically detect the new
reference values after you have changed the tire
pressure. However, you can also set reference
values manually as described here. The tire
pressure monitor then monitors the new tire
pressure values.

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.
