Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are
identified by
●
are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent 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 below.
Red: stop immediately
Battery charge current
●
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 seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.
<
Engine oil pressure
●
Stop the vehicle immediately
and switch off engine. Check
the engine oil level and top off as
required. If the oil level is correct,
please contact the nearest BMW cen-
ter.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.
<
Brake warning lamp
●
If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. Before driv-
ing further, be sure to comply with the
instructions on pages 110 and 123.

●
In addition, an acoustic signal is
sounded: a tire failure has occurred.
Reduce vehicle speed immediately to
stop the vehicle. Avoid hard brake
applications. As you steer the vehicle,
use caution and avoid overcorrecting.

pages 81, 82
Red and yellow: continue driving
cautiously
The brake warning lamp comes
on together with the yellow indi-
cator lamps for ABS
●
and
ASC+T/DSC:
The entire ABS, CBC,
ASC+T/DSC and ADB control
system has failed. Continue
driving cautiously and defen-
sively. Avoid hard brake applications.
Please have the system checked by
your BMW center as soon as possible.

111 Wheels and tires
Tire inflation pressureInformation for your safetyThe factory-approved tires are matched
to your vehicle and have been selected
to provide optimum safety and driving
comfort when used properly.
It is not merely the tire's service life, but
also driving comfort and – above all else
– driving safety that depend on the con-
dition of the tires and the maintenance
of the specified tire inflation pressure.
Incorrect tire inflation pressure is a fre-
quent cause of tire damage. It also sig-
nificantly influences the roadholding
ability of your BMW.
Be sure to check the tire inflation
pressure, including the space-
saver spare tire or the spare tire, on a
regular basis, at least twice a month
and before every extended journey,
refer to page 24. If this is not done,
incorrect tire pressures can cause driv-
ing instability and tire damage, ulti-
mately resulting in accidents.<
Tire conditionTire tread – tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
Tread depth should not be allowed to
go below 1/8 in / 3 mm, even though
the legally specified minimum tread
depth is 1/16 in / 1.6 mm.
Below 1/8 in / 3 mm tread depth, there
is a great risk of hydroplaning, even at
relatively moderate speeds and with
only small amounts of water on the
road. Tread wear indicators in the
tread-groove base – see arrow – are
distributed around the wheel circumfer-
ence and are labeled on the tire side-
wall with TWI – Tread Wear Indicator. At
a tread depth of 1/16 in / 1.6 mm, the
indicators signal that the legally permis-
sible wear limit has been reached.
Do not drive on a deflated – flat –
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle. Avoid overloading the vehi-
cle so that the permitted load on the
tires is not exceeded. Overloading can
lead to overheating and internal tire
damage.
The ultimate result can assume the
form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. This type of problem can be
caused by contact with curbs, etc. This
is also true for irregularities in the vehi-
cle's handling characteristics, such as a
pronounced tendency to pull to the left
or right. Should this occur, respond by
immediately reducing your speed. Pro-
