Mercedes-Benz AMG GT 53 4MATIC+ 2019, Operator'S Manual

Page: 394 / 530

The system checks the tire pressure and the tire
temperature of the tires installed on the vehicle
by means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in during the first jour‐
ney they are used.
The tire pressure and the tire temperature
appear in the multifunction display
(

page 392).
If there is a substantial pressure loss or if the
tire temperature is excessive, you will be warned
in the following ways:
R
via display messages (
→
page 458)
R
via the h warning lamp in the instrument
cluster (

page 486)
The tire pressure monitoring system is only an
aid. It is the driver's responsibility to set the tire
pressure to the recommended cold tire pressure
suitable for the operating situation. Set the tire
pressure for cold tires using a tire pressure
gauge. Note that the correct tire pressure for the
current operating situation must first be taught-
in to the tire pressure monitoring system.
In most cases, the tire pressure monitoring sys‐
tem will automatically update the new reference
values after you have changed the tire pressure.
You can, however, also update the reference val‐
ues by restarting the tire pressure monitoring
system manually (

System limitations
The system may be impaired or may not function
in the following situations:
R
If the tire pressure is set incorrectly
R
If there is a sudden pressure loss caused, for
example, by a foreign object penetrating the
tire
R
If there is a malfunction caused by another
radio signal source
