Cleaning the rear windowPress the lever briefly:
The intermittent setting of the rear
window wiper is switched on or off.
Press and hold the lever:
The system sprays washer fluid against
the rear window and activates the
wiper. After the lever is released, the
wiper continues to cycle for a few
seconds.
To change the wiper blades, refer to
page 128.
Cleaning the headlamps*If the headlamps are on, they will also
be cleaned every fifth time you activate
the cleaning the windshield 5 mode.
Do not use the washers if there is
any danger that the fluid will freeze
on the windshield, otherwise vision
could be obscured. For this reason, use
an antifreeze agent. Refer to page 108.
Do not use the washers when the reser-
voir is empty, otherwise damage to the
washer pump could result.< Windshield washer jetsThe windshield washer jets are heated
automatically

Tire Pressure Warning (RDW)The conceptThe Tire Pressure Warning (RDW) moni-
tors the tire pressure in all four wheels
while driving. The system is designed to
detect whenever the inflation pressure
in a tire drops significantly, monitoring
the speed of the tires relative to each
other. A flat tire can be detected and
reported because its speed suddenly
deviates drastically from that of the
other tires.
Initializing 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 correcting the
inflation pressure and letting the system
"learn" what condition is required.
1 Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 27),
and adjusting their pressure if neces-
sary.
2 Turn the ignition key to position 2.36mus735
3 Continue to press the button until the
indicator lamp in the instrument
cluster lights up. After a short time,
the indicator lamp will go out auto-
matically.
4 Switch the ignition off.

Special features of winter tires Snow chains
*
Choosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While so-called all season tires (M+S
designation) provide better winter trac-
tion than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally do not achieve the performance of
winter tires.
In the interests of sure tracking and safe
steering response, mount winter tires
which are made by the same manufac-
turer and which have the same tread
pattern at all four wheels.Comply with recommended speed
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 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 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 – and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.The use of narrow-link BMW snow
chains on winter tires is approved only
in pairs and only on the rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Deactivate the Tire Pressure
Warning (RDW) when using snow
chains. The snow chains can lead to
malfunction warnings and undetected
losses in pressure.

Brake fluid Vehicle Identification Number
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the operating safety
and reliability of the brake system, have
the brake fluid changed every two years
by a BMW center. Refer also to the
Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
Brake fluid is hazardous to health and
will damage the vehicle's paint. You
should always store it in its original
container and in a location which is
inaccessible to children. Avoid brake
fluid spills. Do not fill brake fluid beyond
the "MAX" mark in the reservoir. The
brake fluid could ignite upon contact
with hot engine parts and cause serious
burns.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of brake fluid.<
The Vehicle Identification Number is
located in the engine compartment
below the windshield (arrow) and on the
top of the instrument panel. 367us053

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and oper-
ating safety – and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of your vehicle.

Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance
intervals, which are then indicated in
the Service Interval Display. While
conventional systems rely solely on
distance traveled to determine when
service is due, the BMW Maintenance
System considers the actual conditions
under which the vehicle operates.
From the point of view of maintenance,
62,000 miles (100,000 km) accumu-
lated in short-distance urban driving are
not the equivalent of the same distance
covered at moderate speeds in long-
distance highway travel. In response
to this fact, the BMW Maintenance
System monitors operating conditions
as the basis for determining the
optimum service intervals for your indi-
vidual vehicle. The BMW Maintenance System
includes the Engine Oil Service as well
as Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, since oil deteriorates
over time regardless of use, even those
who drive only short distances – signifi-
cantly less than 6,200 miles (10,000 km)
annually – should have the engine oil
changed regularly. Refer to the Service
and Warranty Information Booklet (US
models) or to the Warranty and Service
Guide Booklet (Canadian models).

Storing your vehicle
If you intend to store the vehicle
for longer than three months, have
the maintenance operations described
on this page performed.<
Preparation for storageHave the following operations
performed by your BMW center:
1 Clean and apply a rustproofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in
accordance with approved repair
procedures. Wash the vehicle, clean
the interior and treat painted and
chromed parts. Clean the rubber
seals around the hood, luggage
compartment and doors.
2 Change the engine oil and oil filter
with the engine at operating tempera-
ture. As an additional corrosion
protection measure, a corrosion
inhibitor can be added to the engine
in accordance with the manufac-
turer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the fluid level of the wind-
shield washer fluid reservoir; top up if
necessary.
5 Fill the fuel tank completely to
prevent the formation of condensa-
tion.
6 Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle for
storage1 Dry the parking brake and footbrake
by brake applications to prevent the
brake discs and drums from
corroding.
2 Park the vehicle in a covered, dry,
and well-ventilated room. Place the
transmission in 1st gear. Chock the
wheels to prevent the vehicle from
rolling if necessary. Do not apply the
parking brake.
3 Remove the battery, charge it
completely and store it in a cool (but
frost-free) room.
M roadster:
4 Remove the hardtop
* and store it
separately. Refer to page 97.
5 Close the convertible top.
During storageRecharge the battery every six months.
If it is not recharged, it will not be
serviceable. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.Removing the vehicle from
storageRecharge the battery if the "Magic Eye"
turns black. Refer to page 141.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement if necessary. Refer to
the Service Manual.
