1. Reduce your speed and carefully stop the

car. Avoid sudden braking and steering

maneuvers.

2. If all four wheels are shown in yellow, iden-

tify the damaged wheel on the vehicle.

3. Repair the flat tire with the M Mobility Sys-

tem, refer to page 217.

Have the tire replaced by a BMW center or a

workshop that is informed in the handling of

TPM and that works according to BMW repair

procedures with correspondingly trained per-

sonnel.

Malfunction

The small warning lamp flashes in

yellow and then lights up continu-

ously; the larger warning lamp comes

on in yellow. On the Control Display,

the wheels are shown in gray and a message

appears. No punctures can be detected.

This type of message is shown in the following

situations:

> If there is a malfunction

Have the system checked.

> If a wheel without TPM electronics has

been mounted

> If TPM is temporarily malfunctioning due to

other systems or devices using the same

radio frequency.

Message for unsuccessful system

reset

The warning lamp lights up yellow. A

message appears on the Control Dis-

play. The system is not reset after a

tire has been changed, for example.

Check the tire inflation pressure and reset the

system, refer to page 86.

Declaration according to NHTSA/

FMVSS 138

Tire Pressure Monitoring Systems

Each tire should be checked monthly when cold

and inflated to the inflation pressure recom-

mended by the vehicle manufacturer on the

vehicle placard or tire inflation pressure label. If

your vehicle has tires of a different size than the

size indicated on the vehicle placard or tire infla-

tion pressure label, you should determine the

proper tire inflation pressure for those tires. As

an added safety feature, your vehicle has been

equipped with a tire pressure monitoring sys-

tem, TPMS, that illuminates a low tire pressure

telltale when one or more of your tires are signif-

icantly under-inflated. Accordingly, when the

low tire pressure telltale illuminates, you should

stop and check your tires as soon as possible,

and inflate them to the proper pressure. Driving

on a significantly underinflated tire causes the

tire to overheat and can lead to tire failure.

Underinflation also reduces fuel efficiency and

tire tread life, and may affect the vehicle’s han-

dling and stopping ability. Please note that the

TPMS is not a substitute for proper tire mainte-

nance, and it is the driver’s responsibility to

maintain correct tire pressure, even if underin-

flation has not reached the level at which the

TPMS low tire pressure telltale illuminates.

The TPMS malfunction indicator is combined

with the low tire pressure telltale. When the sys-

tem detects a malfunction, the telltale will flash

for approximately one minute and then remain

continuously lit. This sequence will continue

upon subsequent vehicle startups as long as

the malfunction exists. When the malfunction

indicator is illuminated, the system may not be

able to detect or signal low tire pressure as

intended. TPMS malfunctions may occur for a

variety of reasons, including the installation of

replacement or alternate tires or wheels on the

vehicle that prevent the TPMS from functioning

properly. Always check the TPMS malfunction

telltale after replacing one or more tires or

wheels on your vehicle to ensure that the

replacement or alternate tires and wheels allow

the TPMS to continue to function properly.

Servotronic

The concept

"Servotronic" varies the steering force required

to turn the wheels as a function of the speed at

which you are driving.
