Indicator and warning lampsTechnology that monitors itselfMany of the systems of your BMW mon-
itor themselves automatically, both dur-
ing engine starts and while you are driv-
ing. Indicator and warning lamps that
are identified by "l" are tested for
proper functioning whenever the igni-
tion 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 below.
Red: Stop immediately
Battery charge current l
The battery is no longer being
charged. There is a malfunction
of the alternator V-belt or in the charg-
ing circuit of the alternator. Please con-
tact the nearest BMW center.
If the ribbed V-belt is defective, do
not continue driving. The engine
could be damaged due to overheating.
If the ribbed V-belt is defective, in-
creased steering effort is also re-
quired.<
Engine oil pressure l
Comes on while the engine is
running and the "STOP! ENGINE
OILPRESS" message appears in the
Check Control: Stop vehicle and switch
off engine immediately. Check level of
oil in engine, top up as required. If oil
level is correct: Please contact the
nearest BMW center.
Do not continue driving. The en-
gine could be damaged because
of inadequate lubrication.<
Tire Pressure Control (RDC)
* l
In addition, there is an acousti-
cal warning signal: A tire failure
has occurred. Reduce vehicle speed
immediately and stop the vehicle. Avoid
hard brake applications. Do not over-
steer. For additional information: Refer
to page 92.
Parking brake
*, brake hydraulic
system l
Comes on when you engage the
parking brake. For additional informa-
tion: Refer to page 69.
Comes on although the parking brake is
released: Have the brake fluid level
checked. Before driving further, be
sure to read the notes on pages 130
and 152.
Also comes on with the message
"CHECK BRAKE PADS" in the Check
Control.

>CHECK TIRE PRESSURE
*
Check and correct the tire inflation
pressure to specifications at the earli-
est opportunity (next stop for fuel).
Refer to page 92.
>TIRE CHECK INACTIVE
*
A temporary interference of the RDC
or a system fault. Refer to page 93.

necessary and brake pedal travel may
be significantly longer.
Have the fault checked by your

Displays after completion of tripAll of the malfunctions registered during
the trip appear consecutively when the
key is turned to Position 0.
One of the following displays may ap-

Winter tires Snow chains
*
Do not exceed specified
maximum speeds
Never exceed the maximum
speed for which the tires are
rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to be-
low 0.16 inches (4 mm), and should
thus be replaced.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
StorageStore tires in a cool, dry place, away
from light whenever possible. Protect
the tires against contact with oil, grease
and fuel.Use narrow-link BMW snow chains
on
summer or winter tires only in pairs and
only on the rear wheels. Comply with all
manufacturer's safety precautions when
mounting the chains.
It is not possible to mount snow
chains on tires with 17-inch
wheels.<

Caring for your carWashing your carYou can have your new BMW washed
in an automatic car wash. Car wash
systems that do not employ brushes are
preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the car.
To prevent spots, avoid washing when
the hood is still warm, or immediately
after and during exposure to strong
sunlight.
When using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). If you are
uncertain, consult the manager of the
car wash
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system
>The vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.Vehicles with rain sensor
*:
Clean the windshield regularly. Wax
from automatic car washes or insects,
for example, can cause malfunctions in
the function of the rain sensor.
Turn the rain sensor off in auto-
matic car washes. If you do not,
damage may occur if the wipers switch
on unintentionally.<
Parts of the car which are inaccessible
to the automatic washer Ð such as door
sills, door and hood edges, etc. Ð
should be cleaned by hand.
In the winter months, it is especially im-
portant to ensure that the car is washed
on a regular basis. Large quantities of
dirt and road salt are difficult to remove,
and they also cause damage to the ve-
hicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's sur-
face. Inadequate distance and exces-
sive pressure can damage or weaken
the finish, making it more susceptible to
subsequent attack. In addition, mois-
ture could penetrate to vehicle compo-
nents, leading to long-term damage.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (scratches). Never use abra-
sives or strong solvents to clean the
covers
>Remove dirt and contamination
(such as insects) by soaking with
BMW Car Shampoo and then rinsing
with plenty of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use an ice scraper.<
After washing the car, apply the
brakes briefly to dry them. Braking
efficiency might otherwise be reduced
by the moisture, and the brake rotors
could also be corroded.<
