Tire replacement Tire rotation
Do not use retreaded tires as this
could negatively affect driving
safety. This is due to the possible varia-
tions in casing structures and, in some
instances, to their extreme age, factors
which can lead to a decrease in their
durability.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 3200 indicates that the tire was
manufactured in week 32 of 2000.
BMW recommends the replacement
of all tires when the tires are no more
than 6 years old, even if a tire usage of
10 years is possible.
Spare tires over 6 years old should be
used only in case of emergency. A tire
of this age should be replaced by a new
tire immediately, and should not be
fitted together with new tires.
Between the axlesTread wear at the front and rear axle is
different and will vary according to indi-
vidual driving conditions. In the interest
of safety and optimal vehicle response,
we advise against rotating wheels from
front to rear and vice versa.
If rotating the wheels between the axles
is under consideration for economic
reasons, the costs for remounting the
wheels must be calculated against any
savings which might result from the
anticipated extension in tire life. Rota-
tion should always be carried out at
short intervals (max. 3,000 miles/
5,000 km). Consult your BMW center for
more information.Should you decide to rotate the wheels,
it is essential to comply with the
following:
Rotate wheels on the same side of the
vehicle only, otherwise braking effi-
ciency and road grip could be adversely
affected.
Following rotation, correct the tire infla-
tion pressure.
If tires with different sizes are
mounted on the front and rear
axles (refer to page 103), the wheels
may not be rotated from one axle to the
other.<

Wheel and tire combinationsThe right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
leading to serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
For wheel and tire specifications
approved by BMW, refer to the informa-
tion on page 103.
The correct wheel and tire combi-
nation affects different systems
such as ABS, DSC and RDW. The func-
tion of these systems is impaired if
improper wheel and tire combinations
are used.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel and tire combination
following a flat tire as soon as
possible.<
Codes on tires and wheelsThe code on tires has the following
meaning.
Codes on radial tires:
The speed rating indicates the
approved maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 149 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
ZR = over 149 mph (240 km/h) Example:
Nominal width
in mm
Aspect ratio in %
Belt rating ID code
for radial tires
Wheel diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
205/60 R 15 91 H
All season and winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes on light-alloy wheels:
Protect valve inserts against dirt by
using screw-on valve caps.
Dirt in the valves frequently leads to
slow leaks.Storage Store tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against
contact with oil, grease and fuel. Example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches
Extended hump on
the 2 rim shoulders

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.

Do not work on your vehicle
without appropriate skills. Always
switch off the engine and allow it to
cool down before working in the engine
compartment. Always disconnect the
battery before working on any electrical
systems or equipment, especially when
these are located within the engine
compartment. Comply with all appli-
cable instructions and warnings. If you
are not familiar with all guidelines, have
the work performed by your BMW
center. Otherwise, safety hazards for
vehicle occupants and other road users
may occur as a result of improper
handling of components and mate-
rials.<

Engine oil To check oil level1 Park the vehicle on a level surface.
2 Switch the engine off after it has
reached normal operating tempera-
ture.
3 After approx. 1 minute, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material.
4 Push the dipstick carefully all the way
into the guide tube and pull it out
again.
5 The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.36mde790
The space between the two marks on
the dipstick corresponds to approx.
1.4 US quarts (1.3 liter). Do not fill
beyond the upper mark on the dipstick.
Excess oil will damage the engine.36mde791
To add oilWait until the level has dropped to just
above the lower mark before adding oil.
Do not wait until the oil drops below the
lower mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, differential and
the power steering system.< 36mde792

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).

Caring for your vehicleWhen 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). Consult the
car wash operator if necessary.
>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 ample water is
available for washing and rinsing.
Parts of the vehicle which are inacces-
sible to the automatic washer – such as
door sills, door and hood edges, etc. –
should be cleaned by hand.
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Large quan-
tities of dirt and road salt are difficult to
remove, and they also cause damage to
the vehicle.If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's
surface. Inadequate distance and
excessive pressure can damage or
weaken the finish, making it more
susceptible to subsequent attack. In
addition, moisture could penetrate to
vehicle components, leading to long-
term damage.<
When cleaning the headlamps,
please observe the following:
>Do not rub dry (this causes scratches)
and never use abrasives 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 – never
use a scraper.<
After washing the vehicle, apply
the brakes briefly to dry them.
Braking efficiency might otherwise be
reduced by the moisture and the brake
discs could also be corroded.<

Caring for your vehicleCleaning and care of the
convertible top – M roadsterThe appearance and life of the convert-
ible top are highly dependent on its
proper care and operation. You should
pay particular attention to the following
instructions if your vehicle has a light-
colored top.
Protect the vehicle from exposure to
intense sunlight whenever possible by
parking it in the shade. This will prevent
the paint, rubber and fabric-covered
parts from being attacked.
Never fold up the convertible top and
store it in the convertible top compart-
ment when wet, dirty or frozen, since
mildew stains and rub spots may result.
To prevent the formation of creases in
the rear window and mildew stains in
the fabric, do not leave the top folded
in the convertible top compartment for
extended periods.
If the vehicle will be parked for lengthy
periods in an enclosed space, be sure
that the convertible top is dry and that
there is adequate ventilation.Clean off bird droppings immediately,
since they attack the convertible top
and cause the rubber seals to swell due
to their caustic characteristics.
Besides water, treat rubber seals only
with talcum powder, rubber care prod-
ucts or silicone spray, particularly when
they feel dry or tend to stick.
Eliminate noises such as squeaks with
lubricant spray.
Never use sharp-edged objects to
clean snow or ice from the rear window.
The use of deicing spray is not
approved. Due to the danger of
damage and discoloration, do not apply
adhesive tape, stickers, etc., to the
window or cover it with plastic film.
Depressions and discoloration may
occur in the convertible top as a result
of improper maintenance and cleaning
or as the result of stresses from exces-
sive use. The convertible top and its
seams may also develop leaks. These
occurrences are not covered by the
warranty. For repairs, please consult
your BMW center.
Special wash for the topIn the case of more extensive dirt,
which is especially visible on light-
colored top materials, clean the top
with the BMW Convertible Cleaning
Set. Please proceed as follows:
Spray the convertible top with the
cleaning agent and then rub with a well-
dampened sponge using circular
motions until a foam develops. Then you
can finish washing the vehicle in an
automatic car wash. After three to five
washings the convertible top should be
treated with a special impregnating
spray. Please follow the instructions on
the spray can.
Use the cleaning and car-care
products that you can obtain at
your BMW center.<

Caring for your vehicleRear window cleaningWhile the roadster's rear window has
the advantage of being extremely flex-
ible, there is the disadvantage that it
has a relatively soft surface. For this
reason, clean the rear window only with
a soft, antistatic cloth or with BMW
Convertible Rear Window Cleaner.
If you wash the vehicle frequently in
brush car washes, and in particular in
those with hard brushes, faint scratches
in the rear window may result. With the
window replacement system you can
replace a heavily scratched window at a
relatively low price. Please contact your
BMW center for additional information.
Do not use spot removers, paint
thinners, solvents, gasoline or
similar substances for removing spots
from the convertible top or from the
rear window. These materials destroy
the rubber seals, which will lead to
leaks. Use only BMW-approved
cleaners.<
Exterior finishTo provide effective corrosion protec-
tion, multilayer paintwork is applied at
the factory. Cataphoretic immersion
priming techniques are supplemented
using special body-cavity protectants,
with the application of specially-devel-
oped and extensively tested materials.
A layer of flexible PVC is first applied
to the undercarriage. Following this, a
comprehensive undercoating treat-
ment with a wax-based protectant is
applied.
Regular care makes an important
contribution to maintaining the safety
and value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on
vehicle finishes have led paint and
vehicle manufacturers to initiate
programs designed to further improve
the durability of their finishes. Despite
this, environmental factors which occur
locally or regionally can have negative
effects on the finish of your vehicle.
These should guide you in determining
the frequency and extent of your efforts
to maintain the vehicle finish.
Depending upon material and type
of impact (perforation of paint layer),
physical stresses from sand, road salt, gravel, etc., can cause corrosion to
start extending beneath the finish,
starting at the point of impact.
Road dirt, tar spots, dead insects,
animal droppings (strong alkali concen-
tration) and tree excretions (resins and
pollen) all contain substances capable
of causing damage when allowed to
remain on the finish of your vehicle for
any period of time (spots, etching,
flaking, separation in the top coat).
In industrial areas, deposits of flue dust,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other envi-
ronmental pollutants will damage the
vehicle's finish unless adequate care is
provided – even though this is generally
limited to the outside horizontal
surfaces.
In coastal regions, high levels of atmo-
spheric salt and humidity promote
corrosion.
In the tropics, in addition to ultra-violet
radiation and high humidity, tempera-
tures over +105 7 (+40 6) in the
shade are common. Under those condi-
tions, light paints can reach tempera-
tures up to +175 7 (+80 6) and dark
paints up to +250 7 (+120 6).

Caring for your vehicleCaring for the vehicle finishRegular washing is a preventive
measure against long-term effects from
substances which are harmful to the
vehicle's finish, especially if you drive
your vehicle in areas with high levels of
air pollution or aggressive natural
substances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive
substances. Failure to do so can lead to
changes in the paint's chemical struc-
ture or to discoloration. Gasoline spilled
during refueling, oil, grease and brake
fluid should always be cleaned away
immediately, as should bird droppings
(finish damage).
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use
cleaning fluid or alcohol with a clean
cloth or cotton pad to remove. Remove
tar spots with tar remover. After
cleaning, the affected areas should be
waxed to ensure continued protection.
Use the cleaning and car-care
products that you can obtain at
your BMW center.<
Waxing your vehicleProtect the finish using carnauba or
synthetic-based waxes only.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the
surface.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Use the cleaning and car-care
products that you can obtain at
your BMW center.<
Paint damageYou can touch up minor paint flaws with
BMW spray paint or a BMW touchup
stick.
The color code for your vehicle is
provided on a tag located near the
vehicle data plate and on the first page
of the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
Damage caused by flying stones,
scratches, etc., must be touched up
without delay to prevent rust from
forming.
If corrosion has started to form in an
area with paint damage, remove all rust
and clean the area. Finally, apply the
finish coat. Wait a few days, then polish
the repaired area. Finish by applying a
wax preservative.
More extensive paint damage should
be repaired professionally in accor-
dance with the manufacturer's instruc-
tions. Your BMW center uses original
BMW finish materials in accordance
with approved repair procedures.
Use the cleaning and car-care
products that you can obtain at
your BMW center.<
