natural, even pressure drop in all four
tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
> When you are driving on snow-covered
or slippery road surfaces
> If you are using a sports driving style:
slip on the drive wheels, high lateral
acceleration
> False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted
> When you are driving with the compact
wheel, the Flat Tire Monitor is unable to
function.
Initializing the system
Perform the initialization immediately
after correcting the inflation pressure,
after changing a tire or changing a wheel or
all wheels. A drive is necessary for this pur-
pose.<
Control Center, for principle details, refer to
page 16:
1. Before beginning driving, start the
engine, but do not drive off
2. Open the menu
3. Select "Vehicle settings" and press the
controller
4. Select "FTM" and press the controller
5. Select "Set tire pressure" and press the
controller
6. Select "Yes" and press the controller
7. Drive off.
The message "Initializing" is displayed.
It takes a few minutes before the Flat Tire
Monitor can detect and report a flat tire.
After the initialization is completed, the
message "Active" is displayed.
If a flat tire is detected during initialization,
a message appears on the Control Display.
When driving with snow chains or
with the compact wheel, do not initial-
ize the system.<
Flat tire
Indicator lamp
The symbol in the instrument clus-
ter lights up in red and a simulta-
neous message appears on the
Control Display. In addition, an acoustic
signal sounds.
Please note any supplementary information
that appears on the Control Display. You
can find more information on the Check
Control starting on page 68.
1. Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2. Identify damaged tire
If identification is not possible,
contact your BMW center.<
3. Replace the damaged wheel, refer to
Changing a tire on page 187.
Vehicles with run-flat tires:
1. Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
edges of the run-flat tires, inflation
pressure loss can not usually be recog-
nized from the outside, refer to Run-flat
tires on page 175.<
2. To continue driving, comply with the
instructions for driving with damaged
tires on page 175.
