We recommend winter tires (M+S radial
tires) for operation under inclement win-
ter driving conditions. Although all-sea-
son M+S tires provide better winter
traction than standard summer tires
with H, V, W and ZR speed ratings, they
generally fail to provide the same levels
of performance as standard snow tires
in winter driving.
If you fit winter tires, install radial tires
of the same tread configuration and
from a single manufacturer on all four
wheels (better still: on all five wheels).
This ensures safe tracking and steering
response.
Fit BMW-approved winter tires only.
Any BMW Retailer will be glad to pro-
vide you with information on the best
winter tires for your particular driving
conditions.Winter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in (4 mm), and should thus
be replaced.
Observe the specified tire inflation
pressures - and be sure to have the
wheel and tire assemblies balanced
every time you change the tires!
a
Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and ac-
cidents.
Have this work performed by skilled pro-
fessionals only. Your BMW Retailer will
be glad to assist you.c
Store tires in a cool, dry place, away
from light whenever possible. Protect
the tires from contact with oil, grease
and fuel.

Washing your carRight from the start, you can wash your
new BMW either by hand or in an auto-
matic car wash. BMW Convertible: For
instructions on cleaning and care of the
convertible top, refer to page 136 ff.
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,
ensure that
dno damage occurs to vehicles with
add-on body elements (e.g., spoilers,
telephone aerials). Consult the car
wash operator if necessary
dthe vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.
Loosen and remove stubborn dirt and
dead insects before washing the car.
a
Always maintain an adequate dis-
tance between the spray source and the
vehicle's surface when using spray
wands and high-pressure washers. In-
adequate distance and excessive pres-
sure can damage or weaken the finish,
making it more susceptible to subse-
quent attack. In addition, moisture could
penetrate to vehicle components, lead-
ing to long-term damage.c
Parts of the car which are inaccessible
to the automatic washer - such as door
sills, door and hood edges, etc. -
should be cleaned by hand.
b
Please observe the following
when cleaning the headlamp covers:
dDo not clean by wiping with a dry
cloth (scratches). Never use abra-
sives or strong solvents to clean the
covers.
dRemove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with
plenty of water.
dAlways use a de-icer spray to remove
accumulated ice and snow Ð Never
use a scraper!cIn the winter months, it is especially
important to ensure that the car 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.
a
After washing, the brakes may be
wet and thus less effective! Apply the
brakes briefly to dry them.c

Never use spot remover, paint thinner,
solvents, gasoline etc. to remove spots
from the convertible top and from the
rear window, as these substances
destroy the rubber seals and lead to
leaks. Use only BMW-approved clean-
ers.
In addition to the advantage of being
extremely flexible, the rear window also
has the disadvantage of having a rela-
tively soft surface. For this reason, only
clean the rear window with a soft, anti-
static 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
authorized BMW Retailer for additional
information. b
A full range of car-care products is
available from your BMW Retailer.c
a
Cleaning agents can contain sub-
stances that are dangerous or bad for
your health. Therefore always observe
the warnings and danger notices on the
package.
Open the doors or windows on your ve-
hicle when cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically in-
tended for this application.c
Hardtop:Please follow the instructions for car
care from page 131.If the vehicle is to be temporarily stored
for more than three months, have the
following maintenance performed by
your BMW Retailer:
1 Cleaning, preservation and retreat-
ment of the engine, engine compart-
ment, underbody, axles and
subassemblies in accordance with
the factory speciÞcations. Vehicle
washing with interior cleaning fol-
lowed by paint and chrome care.
Clean rubber seals of the hood, lug-
gage compartment lid and doors and
rub with either talcum powder or
glycerine oil.
2 Change engine oil and oil Þlter at
operating temperature. As an addi-
tional corrosion protection measure,
an anti-corrosive agent can be added
to the engine in accordance with the
manufacturer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the acid level in the battery
cells and add distilled water if neces-
sary.
5 Increase the tire inßation pressure to
50.9 psi (3.5 bar).
