message. The
000Atire pressure loss warning
lamp in the instrument cluster (Y page 218)
lights up.
The tire pressure is show nin2red rectangles.
The pressure of the tire concerned is shown
in one of the two rectangles (Y page 192).
Additionally, a warning tone sounds.
Each tire that is affected by a significant loss
of pressure is highlighted in the pressure
display.
Restarting the tire pressure monitor When you restart the tire pressure monitor,
the currently set tire pressure are taken as
reference values for monitoring.
In most cases, the tire pressure monitor
detects the new reference values
automatically, e.g. after you have:
R changed the tire pressure
R changed wheels or tires
R installed new wheels or tires
However, you can also define reference
values manually as described here.
Before restarting the tire pressure
monitor:
X Set the tire pressure to the value
recommended on the Tire and Loading
Information placard or the tire pressure
table on the B-pillar on the driver's side
(Y page 278).
Observe the notes on tire pressure when
doing so (Y page 278).
X Make sure that the tire pressure is correct
on all four wheels. Restarting the tire pressure monitor
(vehicles without steering wheel
buttons):
X
Turn the key to position 2in the ignition
lock.
X Press the 0004menu button on the
instrument cluster repeatedly until the
display shows the following message:
+CAL- TPMS X
Press the 000Ebutton on the instrument
cluster.
The display shows:
OK TPMS The tire pressure monitor activation
process has begun. The tire pressures
measured for the individual wheels are
stored as the new reference values,
provided that the tire pressure monitor
considers them to be plausible.
If you wish to cancel the restart:
X Press the 000Fbutton or the 0004menu button
on the instrument cluster.
The activation process is canceled
automatically if 30 seconds elapse with no
input.
Restarting the tire pressure monitor
(vehicles with steering wheel buttons):
X Turn the key to position 2in the ignition
lock.
X Press the 0010or0007 button on the
steering wheel repeatedly until the
standard display is shown (Y page 182).
X Press the 0001or0009 button on the
steering wheel repeatedly until the current
pressure of the individual tires is displayed
or the display shows the following
message:

it is unscrewed, you can use the valve insert
from tire sealant bottle 0019after you have
used the tire sealant.
X Unscrew the valve insert from the valve of

If possible, inflate the tire to the
recommended tire pressure. You will find a
table of recommended tir epressure on the
Tire and Loading Information placard 10
or
the tire pressure plate on the B-pillar on the
driver's side of the vehicle (Y page 278).
X Then press 0on tire inflation compressor

X Screw the valve cap onto tire valve 001C.
X Observe the following notes and
instructions:
R
Tire pressure of 300 kPa (3.0 bar/
43.5 psi) not reached (Y page 301).
R Tire pressure of 300 kPa (3.0 bar/
43. 5psi) reached (Y page 301).
Tire pressure of 300 kPa (3.0 bar/
43.5 psi) not reached G
WARNING
If the specified tire pressure is not reached,
the tire is too severely damaged.T he tire
sealant cannot offer assistance with a flat tire in this case. Damaged tires as well as tire
pressure that is too low can impair the braking
and driving characteristics. There is a risk of
an accident.
Do not drive any further. Notify a qualified
specialist workshop.
i The Mercedes-Benz Service24h
telephone numbers can be found on a
sticker in the driver's door entrance area
and in the vehicle Maintenance Booklet.

WARNING
At ire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tire that
has been repaired using tire sealant.
The maximum speed for a tire sealed with tire
sealant is 50 mph (80 km/h).
The "max. 50 mph" (80 km/h) sticker must
be affixed within the driver's field of vision.
X Turn the pressure release screw on
pressure gauge 0023counter-clockwise and
bleed the system.
X Turn the key in the ignition lock to
position 0.
X Pull connector 0024on the tire inflation
compressor out of the 12 V socket.
X Clean the valve core extractor with clean
water.
X Remove angled valve adapter 0006from valve
