BMW 745i Manual Do Proprietário

Check the tire inflation pressure regu-
larly and correct it if necessary, refer 

Do not initialize the system when snow 
chains are fitted. False alarms and unde-
tected loss of pressure may occur in such 
situations. 
When driving on snow-covered or slippery 
surfaces, it may take some time for a loss of 
tire pressure to be indicated. 
A sports driving style – spinning of the 
driven wheels, high lateral accelerations – 
can likewise result in a delayed response 
from the Flat Tire Monitor.

The symbol will appear in yellow in the 
Check Control and a message will appear. 

Please refer to the additional information 
supplied in the Control Display, and have 
the system inspected at your BMW center. 

TPM monitors inflation pressures in all four 
tires while you drive. The system provides 
an alert whenever the inflation pressure 
drops significantly below the specified 
pressure in one or more tires. 

To initialize TPM, start by checking the 
inflation pressures in all four tires and com-
paring them with those specified in the 
table on page 

, correcting them as nec-

essary.Then proceed to initialize the 
system. 

This symbol will appear in the 
Check Control to inform you when 
the inflation pressure varies from 

that stored in the system. A text message 
appears at the same time.
Please take note of the additional informa-
tion in the Control Display.
You can find more information on the 
Check Control starting on page 

.

The TPM cannot alert you to severe 
and sudden tire damage caused by 

external factors.

1.

With the vehicle parked, switch on the 
ignition 

2.

Select "TPM" from the "Settings" menu 
and confirm your selection. The initial-
ization menu appears. 

1.

Select and confirm

2.

TPM is initialized. A message appears 
in the Check Control 

3.

After several minutes of driving TPM will 
adopt the tires' current inflation pres-
sures as its references. 
The current data appear in the Control 
Display. These figures are more accu-
rate than those that appear on the infla-
tion gauges at filling stations, etc. 

The only time you will need to repeat this 
procedure is after correcting your tire pres-
sures. Because TPM automatically 
assumes operation each time you switch 
on the ignition, it is on duty whenever you 
drive. 

If the system detects a flat tire during 
the initialization process, the tires in 

the Control Display will appear in red.
