Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

l

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for
different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react to this in the
following section.

Red: stop immediately

Battery charge current



l

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. Please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and
serious engine damage. If the drive belt
is defective, increased steering effort is
also required.

<

Engine oil pressure


l

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level and top off as
required. If the oil level is correct,
please contact the nearest BMW
center.
Do not continue driving, as the
engine could sustain serious
damage from inadequate lubrication.

Tire inflation pressures The specified inflation pressures are
provided on a sticker attached to the
B-pillar and visible with the driver's
door open.Checking tire pressuresAll pressures are specified in the stan-
dard units of pressure for your country,
psi or kilopascal, and apply to cold tires
(tires at ambient temperature, refer to
tire pressure table on the following
page).
Vehicles with Tire Pressure Monitor
(RDC)/Flat Tire Monitor:
After correcting the inflation pressures,
reactivate the system, refer to
pages 78, 80.
Another instruction plate regarding
inflation pressures on the door pillar
indicates which system is equipped on
your vehicle.
Check the tire pressures on a
regular basis Ð at least twice a
month Ð and before every extended
journey. Otherwise, incorrect tire pres-
sure can lead to driving instability, tire
damage and accidents.
Remember to check the inflation pres-
sure in the space-saver or standard
spare tire.

Inflate the spare tire to the highest infla-
tion pressure of any tire on your
vehicle.<
Comply with tire approval
specificationsThe inflation pressures in the table
apply to BMW approved tire sizes and
tire manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
made by other manufacturers.
Your vehicle is equipped with tires that
not only meet US standards, but also
European standards. We recommend
the exclusive use of BMW approved
tires.

Tire Pressure Monitor (RDC)
*
The conceptRDC monitors the tire pressures at all
four wheels while the vehicle is moving.
The system provides an alert whenever
the inflation pressure drops significantly
below the specified pressure in one or
more tires.
In order for the system to learn the
correct tire inflation pressure, check the
inflation pressure in all tires according
to the inflation pressure table on
page 25 and make corrections as
necessary. Then activate the system.
This indicator lamp in the instru-
ment cluster will inform you if
the tire pressure is not correct.
To activate the system1. Turn ignition key to position 2 (do not
start the engine)
2. Press the button long enough for the
yellow indicator lamp in the instru-
ment cluster to light up for a few
seconds
3. After a few minutes driving time, the
RDC adopts the current pressure
levels as the reference, and from that
point on, can detect and report a flat
tire.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.
In the event of loss in inflation
pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the yellow
indicator lamp will come on.
This alerts you to have the tires inflated
to the specified pressures as soon as
possible.
If you are prompted to check the
tire pressure shortly after a
correction has been made, this indi-
cates that the corrected values were
not accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. Then activate the system once
again.<

Tire Pressure Monitor (RDC)

In the event of a flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic
signal is sounded.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the
wheel and flat tire.
The space-saver spare tire is
provided for temporary use only in
the case of a tire failure. It does not
have RDC electronics and is not moni-
tored. The spare tire
that has the same
dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics
and will be also monitored once the
tires have been mounted and the
system activated.<
RDC cannot alert you to severe
and sudden tire damage caused
by external factors.<
Have the tires changed by your
BMW center.
Your BMW center has the information
needed for working with RDC and is
equipped with the necessary special
tools.<
System interferenceLocal devices using the same radio
frequency can interfere with RDC.
The yellow indicator lamp will come on
during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

Flat Tire Monitor
*
The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires in order to detect and warn of any
substantial pressure loss.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.
To initialize the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after adjusting the
inflation pressure and letting the system
"learn" the correct pressures.
1. Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table on page 25,
and correct their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press button as long as you need to
until the indicator lamp in the instru-
ment cluster lights up. After a little
while, the indicator lamp will go out
by itself
4. After a few minutes driving time, the
Flat Tire Monitor adopts the current
pressure levels as the reference, and
from that point on, can detect and
report a flat tire.

Flat Tire Monitor
*
Activate/deactivate the systemThe Flat Tire Monitor automatically
assumes operation whenever you turn
the ignition key to position 2. Unless
manually deactivated, it is always on
during normal vehicle operation.
To deactivate the system: press the
button, the yellow indicator lamp comes
on.
To activate the system: press the
button again, the indicator lamp goes
out.
You should deactivate the system
before driving with snow chains, as the
chains can generate spurious warnings
and/or prevent the system from
detecting actual pressure loss.
In the event of a flat tire
The red warning lamp in the
instrument cluster lights up to
warn of pressure loss and tire
failure. This visual alert is accompanied
by an acoustic warning signal. Reduce
your speed immediately, and steer and
brake gently as you bring the vehicle to
a stop.
To reset the warning lamp: after
replacing the flat tire you will need to
reset the red warning lamp manually:
maintain pressure on the Flat Tire
Monitor button until the warning lamp
goes out. Then reinitialize the system.
The Flat Tire Monitor cannot
provide you with advance warning
of sudden and severe tire damage
caused by external factors.
The system also does not detect the
gradual and minor loss of pressure that
all tires display over extended periods
of time.<
Check the tire inflation pressures
on a regular basis, correcting
them as necessary, refer to page 24.
The system may respond to operation
on slippery or snow-covered road
surfaces with false warnings or delays
in detecting actual pressure loss.
Performance-oriented driving (slip at
the drive wheels, high rates of lateral
acceleration) can also increase the time
that the Flat Tire Monitor requires to
detect a flat tire.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on
until the problem is corrected.
Please refer the problem to your BMW
center.
