The tire pressure monitor hasayellow warning
lamp in the instrument cluster for indicating
pressure loss or amalfunction. Whether the
warning lamp flashes or lights up indicates
whether atire pressure is too low or the tire
pressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, the tire
pressure on one or more tires is significantly
too low. The tire pressure monitor is not mal- functioning.
Rif the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, amessage
appears in the multifunction display.O bserve
the information on display messages
(
Ypage 241).
It may take up to ten minutes for amalfunction
of the tire pressure monitor to be indicated. A
malfunction will be indicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after afew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at agas station with apressure gauge. The
tire pressures shown by the on-board computer
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.
The operation of the tire pressure monitor can
be affected by interferenc efrom radio transmit-
ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the vehicle.

monitored.

If the tire pressure monitor detect sapressure
loss in one or more tires, awarning message is
shown in the multifunction display.T he yellow
tire pressure warning lamp then lights up.
RIf the Please Correct Tire Pressuremessage appears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the opportunit yarises.
RIf the Check Tiresmessage appears in the
multifunction display,t he tire pressure in one
or more tires has dropped significantly. The
tires must be checked.
RIf the WarningTireMalfunctionmessage
appears in the multifunction display,t he tire
pressure in one or more tires has dropped
suddenly. The tires must be checked.
Be sure to observe the instructions and safety
notes in the display messages in the "Tires" sec- tion (
Ypage 241).
If the wheel positions on the vehicle are rotated, the tire pressures may be displayed for the
wrong positions for ashort time. This is rectified
after afew minutes of driving, and the tire pres-
sures are displayed for the correctp ositions.
Restarting the tire pressuremonitor
When you restart the tire pressure monitor, all
existin gwarning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tire pressures as the reference values

for monitoring. In most cases,the tire pressure
monitor wil lautomatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can als odefine refer-
ence values manually as described here. The tire
pressure monitor then monitors the new tire
pressure values.
XSet the tire pressure to the valu erecommen-
ded for the corresponding driving situation on

GWARNING
Overloade dtires can overheat, causing a
blowout. Overloade dtires can als oimpair the
steering and driving characteristics and lead
to brake failure. There is arisk of accident.
Observet he loadrating of the tires. The load
rating must be at least hal fofthe GAWR of
you rvehicle. Never overload the tires by
exceeding the maximu mload.
Two instruction labels on you rvehicles how the

Additives
!Operating the engine with fuel additives
adde dlater can leadtoe ngine failure. Do not
mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residueb uildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Compl ywith the instructions
for use on the product label. More information
abou trecommended additives can be
obtained from any authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use bran-
ded fuels that have additives.
The fuel quality available in some countries may
not be sufficient. Residue could build up in the
fuel injection system as aresult. In such cases,
and in consultation with an authorized
Mercedes-Benz Center, the fuel may be mixed
with the cleaning additive recommended by
Mercedes-Benz. You must observe the notes
and mixing ratios specifiedont he container.
Engine oil
General notes
!Never use engine oil or an oil filter of aspec-
ificatio nother than is necessary to fulfill the
prescribeds ervice intervals. Do not change
the engine oil or oil filter in order to achieve
longer replacement intervals than those pre-
scribed. You could otherwise cause engine
damage or damage to the exhaust gas after-
treatment.
Follow the instructions in the service interval display regarding the oil change. Otherwise,
you may damage the engine and the exhaust
gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products (
Ypage 344).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.
You shoul dtherefore only use engine oils and oil
filters that are approved for vehiclesw ith main-
tenance systems.
