294 OperationTires and wheels
Reactivating the Run Flat Indicator
The tire inflation pressure monitor must be
reactivated in the following situations:

if you have changed the tire inflation
pressure


if you have replaced the wheels or tires


if you have installed new wheels or
tires

Using the tire placard on the driver’s
door B-pillar or, if available, the inside
of the fuel filler flap, make sure the tire
inflation pressure of all four tires is cor-
rect.
Warning!
G
When the multifunction display shows the
message
Tire pressure Check tires
,
one or more of your tires is significantly un-
der-inflated. You should stop and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s tire information
placard. Driving on a significantly under-in-
flated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Each tire, including the
spare, should be checked monthly when
cold and set to the recommended tire infla-
tion pressure as specified on the Tire And
Loading Information placard (
page 287)
or on the tire inflation pressure label
(
page 291).
Warning!
G
The Run Flat Indicator does not provide a
warning for wrongly selected tire inflation
pressures. Always adjust tire inflation pres-
sure according to the placard on the driver’s
door B-pillar or fuel filler flap.
The Run Flat Indicator does not replace reg-
ular checks of the tire inflation pressures
since a gradual pressure loss in all four tires
cannot be detected by the Run Flat
Indicator.
The Run Flat Indicator is not able to issue a
warning due to a sudden dramatic loss of
tire inflation pressure (e.g. tire blowout
caused by a foreign object). In this case
bring the vehicle to a halt by carefully apply-
ing the brakes and avoiding abrupt steering
maneuvers.
Warning!
G
The Run Flat Indicator can only warn you in
a reliable manner if you have set the correct
tire inflation pressures for each tire.
If an incorrect tire inflation pressure was
set, the system will monitor the pressure ac-
cording to the incorrect value.

The T

ressure M
onitoring S
ystem
(TPMS) is equipped with a combination low tire
pressure/TPMS malfunction telltale in the in-
strument cluster (
page 29). Depending on
how the telltale illuminates, it indicates a low tire
pressure condition or a malfunction in the TPMS
system itself:


If the telltale illuminates continuously, one
or more of your tires is significantly under-in-
flated. There is no malfunction in the TPMS.


If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system it-
self is not operating properly.

297 Operation
Tires and wheels
Reactivating the TPMS
The TPMS must be reactivated when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
Using the tire placard on the driver’s
door B-pillar (
page 286) or, if avail-
able, the supplemental tire pressure
information on the inside of the fuel fill-
er flap (
page 271), make sure the tire
inflation pressure of all four tires is cor-
rect.

Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(page 145).

Press thej or kbutton repeat-
edly until you see the following mes-
sage:Tire pressure monitor
active
Menu: R-button
TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction 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 properly.i
If a condition causing the TPMS to malfunc-
tion develops, it may take up to 10 minutes for
the system to signal a malfunction using the
TPMS telltale flashing and illumination se-
quence.
The telltale extinguishes after a few minutes driv-
ing if the malfunction has been corrected.
i
Operating radio transmission equipment
(e.g. wireless headsets, two-way radios) in or
near the vehicle could cause the TPMS to mal-
function.
Warning!
G
It is the driver’s responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might loose control over the vehicle.
i
Reactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended for the vehicle operating condition.
Tire pressure should only be adjusted on cold
tires. Observe the recommended tire inflation
pressure on the placard on the driver’s door
B-pillar (
page 286). Some vehicles may have
supplemental tire pressure information for driv-
ing at high speeds (
page 292) or for vehicle
loads less than the maximum loaded vehicle con-
dition (
page 292). If such information is pro-
vided, it can be found on the inside of the fuel
filler flap.

The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
Tire pressure inquiries are made using the
multifunction display. The present inflation
pressures are displayed only after a few
minutes’ travel time.

Switch on the ignition (

Press thej or kbutton until
the current inflation pressures for each
tire appear in the multifunction display.

Possible differences between the readings
of a tire pressure gauge of an air hose, e.g. gas
station equipment, and the vehicle’s control
system can occur. Usually the readings issued by
the control system are more precise.

the individual inflation pressure values are
matched with the tires. The individual values are
displayed after a few minutes driving.

Maintenance
We strongly recommend that you have
your vehicle serviced by an authorized
Mercedes-Benz Center, in accordance with
the Maintenance Booklet at the times
called for by the maintenance service indi-
cator.
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and the maintenance service indicator at
the designated times/mileage may result
in vehicle damage not covered by the
Mercedes-Benz Limited Warranty.Maintenance service indicator
message
The maintenance service indicator mes-
sage will notify you when your next mainte-
nance service is due.
Starting approximately 1 month before
your next maintenance service is due, one
of the following messages will appear in
the right multifunction display while you
are driving or when you switch on the igni-
tion (example service A):
Service A in XXXXX miles (km)
Service A in XXX days
Service A Due now
The type of maintenance service due is in-
dicated in the left multifunction display:
9Basic service (A)½
Extended service (B)Clearing the maintenance service indi-
cator message
The maintenance service indicator mes-
sage is automatically cleared after approx-
imately 30 seconds


after you have switched on the ignition


after you have reached the mainte-
nance service threshold while driving
You can also clear the maintenance ser-
vice indicator message yourself.
i
Vehicles equipped with Maintenance
System (U.S. vehicles) only:
The Maintenance System tracks distance driven
and the time elapsed since the last maintenance
service, calculates other maintenance service
work required, and calls for the next mainte-
nance service accordingly.
i
Vehicles equipped with FSS (Flexible Ser-
vice System) only (Canada vehicles):
The interval between maintenance services de-
pends on your driving habits. A gentle driving
style, moderate engine speeds and the avoid-
ance of short-distance trips will lengthen the in-
terval between services.
