H
Low tire pressure telltale for the
Advanced TPMS* illuminates
continuously.
The Advanced TPMS* detects a loss of
pressure in at least one tire.

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

Read and observe messages in the mul-
tifunction display.
If the tire inflation pressure in the respec-
tive tire(s) has (have) been corrected, the
low tire pressure telltale goes out after few
minutes driving.

392 Practical hintsWhat to do if …Warning!
G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly under-inflated tire causes the tire to over-
heat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping 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 under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.

Check tires
Then restart
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
inoperative
The Run Flat Indicator is malfunctioning.

Have the Run Flat Indicator checked by an authorized
Mercedes-Benz Center.
The Run Flat Indicator has been switched off
due to an error.
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 342).

If necessary, change the wheel (
page 452).

Reactivate the Run Flat Indicator after adjusting the tire
inflation pressure values (
page 344).

No wheel sensors
There are wheels without appropriate wheel
sensors mounted (e.g. winter tires).

Have the Advanced TPMS* checked by an authorized
Mercedes-Benz Center.

Have the appropriate wheel sensors installed by an
authorized Mercedes-Benz Center.
Tire pres. monitor
No wheel sensors
One or more sensors malfunction (e.g. bat-
tery in one or more wheel sensor is empty).
One or more wheels without appropriate
wheel sensors mounted (e.g. spare tire).

Have the Advanced TPMS* checked by an authorized
Mercedes-Benz Center.

Have the wheel sensors installed by an authorized
Mercedes-Benz Center.
The tire pressure for the respective tire is shown in the
multifunction display.

As soon as the causes for the malfunction are no longer
present, the Advanced TPMS* automatically becomes ac-
tive again after a few minutes driving.
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
You may lose control of the vehicle. Contin-
ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.
