Indicator lamp2 flashes. The vehicle
adjusts to the highway level.
The following message appears in the
multifunction display while the level is
being set:When the highway level is reached, indica-
tor lamp2 goes out and the following
message appears in the multifunction dis-
play:
!Keep in mind that in rough or uneven
roads, adjusting the vehicle to a lower
level may cause the vehicle underbody
to come in contact with the road and
result in damage to the vehicle under-
body. Always make sure the vehicle
has sufficient ground clearance before
adjusting it to a lower level.
iThe messages can be cleared by
pressing buttonæ orç on the
multifunction steering wheel.iThe vehicle level is set to highway level
automatically when the vehicle speed
is exceeding 25 mph (40 km/h).

364 OperationTires and wheelsPlacard (Example A) lists the recommend-
ed cold tire inflation pressures for maxi-
mum loaded vehicle weight. The tire
inflation pressures listed apply to the tires
installed as original equipment.
Placard (Example B)
1Vehicle Tire Information placard with
recommended tire inflation pressures
Placard (Example B) lists the recommend-
ed cold tire inflation pressures for maxi-
mum loaded vehicle weight. The tire
inflation pressures listed apply to the tires
installed as original equipment.Important notes on tire inflation
pressure
Tire temperature and tire inflation pressure
are also increased while driving, depending
on the driving speed and the tire load.
If you will be driving your vehicle at high
speeds of 100 mph (160 km/h) or higher,
where it is legal and conditions allow,
consult the placard on the inside of the fuel
filler flap on how to adjust the cold tire in-
flation pressure. If you do not adjust the
tire inflation pressure, excessive heat can
build up and result in sudden tire failure.Be sure to readjust the tire inflation
pressure for normal driving speeds. You
should wait until the tires are cold before
adjusting the tire inflation pressure.
Some vehicles may have supplemental tire
inflation pressure information for vehicle
loads less than the maximum loaded vehi-
cle condition. If such information is provid-
ed, it can be found on the placard located
on the inside of the fuel filler flap.
Tire inflation pressure changes by approxi-
mately 1.5 psi (0.1 bar) per 18°F (10°C) of
air temperature change. Keep this in mind
when checking tire inflation pressure
where the temperature is different from
the outside temperature.
Warning!
G
If the tire inflation pressure drops repeated-
ly:

Check the tires for punctures from
foreign objects.


Check to see whether air is leaking from
the valves or from around the rim.

371 Operation
Tires and wheels

Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu
appears in the multifunction display
(page 168).

Press thej or kbutton repeat-
edly until you see the following
message:Tire pressure monitor
active
Reactivation possible:
R-button

Press the reset button (
page 158).
The following message will appear in
the multifunction display:
Check current
tire pressure?

Press the æbutton.
The following message will appear in
the multifunction display:Tire pressure monitor
reactivatedThe TPMS will now monitor the tire in-
flation pressure values of all four tires.
If you wish to cancel activation:

Press the çbutton.Checking tire pressure electronically
with the Advanced Tire Pressure Moni-
toring System* (Advanced TPMS*),
(Canada only)
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the
vehicle operating condition. Tire pres-
sure should only be adjusted on cold
tires. Observe the recommended tire
inflation pressure on the placard on the
driver’s door B-pillar (
page 357).
Some vehicles may have supplemental
tire pressure information for driving at
high speeds (
page 364) or for vehicle
loads less than the maximum loaded
vehicle condition (
page 364). If such
information is provided, it can be found
on the inside of the fuel filler flap.
iThe Advanced T
ire P
ressure M
onitoring
S
ystem* (Advanced TPMS*) is
equipped with a combination low tire
pressure/TPMS malfunction telltale in
the instrument cluster (
page 24). De-
pending on how the telltale illuminates,
it indicates a low tire pressure condi-
tion or a malfunction in the TPMS sys-
tem itself:


If the telltale illuminates continu-
ously, one or more of your tires is
significantly underinflated. There is
no malfunction in the TPMS.


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

374 OperationTires and wheelsReactivating Advanced 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 357) or, if avail-
able, the supplemental tire pressure
information on the inside of the fuel
filler flap (
page 342), make sure the
tire inflation pressure of all four tires is
correct.

Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu
appears in the multifunction display
(page 168).

Press thej or kbutton repeat-
edly until you see the current inflation
pressures for each tire appear in the
display or the following message
appears in the multifunction display:Tire pressure displayed

only after driving
a few minutes

Press the reset button (
page 158).
The following message will appear in
the multifunction display:
Check current
tire pressure?

Press the æbutton.
The following message will appear in
the multifunction display:Tire pressure monitor

flation pressure values of all four tires.
If you wish to cancel activation:

Press the çbutton.
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 lose control over the vehicle.
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the
vehicle operating condition. Tire pres-
sure should only be adjusted on cold
tires. Observe the recommended tire
inflation pressure on the placard on the
driver’s door B-pillar (
page 357).
Some vehicles may have supplemental
tire pressure information for driving at
high speeds (
page 364) or for vehicle
loads less than the maximum loaded
vehicle condition (
page 364). If such
information is provided, it can be found
on the inside of the fuel filler flap.

Run Flat Indicator
There was a warning message about
a loss in the tire inflation pressure
and the Run Flat Indicator has not
been reactivated yet.

Make sure that the correct tire inflation pressure is set
for each tire.

Then reactivate the Run Flat Indicator.
Run Flat Indicator
inactive
Run Flat Indicator is malfunctioning.

Have the Run Flat Indicator checked by an authorized
Mercedes-Benz Light Truck Center.
Run Flat Indicator
unavailable
The Run Flat Indicator has been
switched off due to an error.

Have the Run Flat Indicator checked by an authorized
Mercedes-Benz Light Truck Center.
Tire pressure
Check tires
The Run Flat Indicator indicates that
the pressure is too low in one or more
tires.

Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. Observe the traffic sit-
uation around you.

Check and adjust tire inflation pressure as required
(page 365).

If necessary, change the wheel (
page 478).

Reactivate the Run Flat Indicator after adjusting the tire
inflation pressure values (
page 365).
