BMW 2006 325Ci Coupe Manual Do Proprietário

The Flat Tire Monitor cannot pro-
vide you with advance warning of 

sudden and severe tire damage caused 
by external factors and does not detect 
the balanced and very gradual pressure 
loss that takes place in all four tires 
over an extended period of time.

<

On the other hand, the following situa-
tions can lead to a delayed detection of 
pressure loss and even to the system 
not functioning:
> Driving on snow-covered or slippery 

roads 

> Performance-oriented driving: slip at 

the drive wheels, high levels of lateral 
acceleration

> When driving with snow chains, false 

warnings and undetected pressure 
losses may occur

> When driving with a space-saver 

spare tire, the Flat Tire Monitor can-
not function.

Each time you correct the pres-
sure in a tire, or change a wheel or 

tire, reinitialize the system immediately 
afterwards. This requires a bit of driv-
ing.

<

1. Before driving off, start the engine 

but do not start driving

2. Press the button as long as you need 

to, but no more than 10 seconds, 
until the indicator lamp in the instru-
ment cluster lights up in yellow for a 
few seconds

3. Drive off.

It takes a few minutes before the Flat 
Tire Monitor can detect a flat tire and 
issue a warning.

When driving with snow chains or 
a space-saver spare tire, do not 

initialize the system.

<

The indicator lamp in the instru-
ment cluster lights up red. This 
visual alert is accompanied by 

an acoustic warning signal.

1. Carefully reduce speed and come to 

a stop. Avoid sudden braking and 
steering maneuvers

2. Determine which wheel is damaged

If this cannot be determined, con-
tact your BMW center.

<

3. Replace the damaged wheel, refer to 

Changing a wheel on page 

.

After replacing the damaged tire, initial-
ize the system.

Vehicles with Run Flat tires:

1. Carefully reduce your speed to under 

50 mph / 80 km/h. Avoid sudden 
braking and steering maneuvers. Do 
not exceed a speed of 50 mph / 
80 km/h
