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.

<

Brake warning lamp

l

If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. Before
driving further, be sure to comply with
the instructions on pages 106 and 118
Brake warning lamp for Cana-
dian models.
Tire Pressure Monitor (RDC)/
Flat Tire Monitor

l

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

absolute minimum; refill as soon as
possible. Do not drive more than
approx. 30 miles (50 km) until you do.
For additional information refer to

Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While all-season tires (M+S designa-
tion) provide better winter traction than
summer tires with the load ratings H, V,
W, Y and ZR, they generally do not
achieve the performance of winter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer having
the same tread configuration on all four
wheels.Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce the tire wears to below 0.16 in
(4 mm), winter tires display a percep-
tible decrease in their ability to cope
with winter driving conditions, and
should be replaced in the interest of
safety.
Comply with the specified tire inflation
pressures Ñ and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against
contact with oil, grease and fuel.Snow chains
*
Use BMW narrow-link snow chains on
summer or winter tires in pairs only and
only on the rear wheels.
BMW 325xi: in an extreme emergency Ð
for instance, with the vehicle stuck on
one side, or when obstructions make it
impossible to reach one tire Ð a chain
may also be mounted on just one tire
for the limited period needed to resolve
the problem.
Comply with all manufacturer's safety
precautions when mounting the chains.
You cannot mount snow chains on the
following tires:
225/50 R 16 92
225/45 R 17 91
245/40 ZR 17
