Special features of winter tires Snow chains
*
Choosing the right tireFor winter road driving, BMW recom-
mends winter tires (M+S radial belt
tires). Although all-season M+S tires
provide better winter traction than stan-
dard summer tires with H, V, W, Y and
ZR speed ratings, they generally fail to
provide the same levels of performance
as standard snow tires in winter driving.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
When selecting winter tires,
remember that you should never
mount anything other than safety tires,
as your vehicle is not equipped with a
spare tire.
For further information, refer to
page 137.<
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which 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. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureOnce the tread depth on winter tires is
less than 0.16 in (4 mm), they are no
longer suitable for winter road driving,
and in the interest of safety should 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.
The use of narrow-link BMW snow
chains is permissible in pairs only on
the rear wheels with winter tires with
tire size 245/45 R 18 96 H. Comply with
all manufacturer's safety precautions
when mounting the chains. Do not
exceed a speed of 30 mph (50 km/h)
while driving with mounted snow
chains.
Do not activate the Flat Tire
Monitor when driving with snow
chains mounted. Malfunction warnings
and undetected losses in pressure are
a possibility when driving with snow
chains.
For further information, refer to
page 67.<

The use of rims and wheel bolts
that do not meet the specifica-
tions of the original factory-installed
equipment will affect the safe operation
of your vehicle and may cause an acci-
dent and personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias-
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle
control.<

Washing your vehicle You 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 vehicle.
In order to avoid spots, do not wash the
vehicle when the hood is warm, or
during or immediately after exposure to
strong sunlight.
In order to protect your convertible top,
do not use washing programs featuring
wax application on your vehicle. The
small amount of beading wax always
used in automatic car washes will not
harm the convertible top.
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). 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 that ample water
is available for washing and rinsing.
Parts of the vehicle which are inacces-
sible 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
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 further damage. In addi-
tion, moisture could penetrate to
vehicle components, leading to long-
term damage.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth. 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 Ð 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
rotors could also be corroded.<

Caring for your vehicleWindow careYou can use window and glass cleaner
to clean inside window surfaces and
mirrors without smearing and streaking.
Never use polishing pastes or abrasive
(quartz) cleansers on mirror lenses.
Clean the wiper blades with soapy
water. The wiper blades should be
replaced twice a year Ð before and after
the cold season.
Use only wiper blades approved
by BMW.<
Caring for other vehicle
components and materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially
during the winter months. However, do
not use aggressive products containing
acids, strong alkalis or abrasives. Do
not use steam cleaners operating at
temperatures above 140 7 (60 6).
Follow the manufacturer's instructions.
Carefully clean chrome parts such as
lamp sockets assemblies, door handles
and similar items with an ample amount
of clean water Ð and shampoo, too, if
necessary Ð especially if there is an
accumulation of road salt. Use a
chrome polish for an additional treat-
ment.
Use water to clean plastic components,
headliners, lamp lenses, and surfaces
sprayed dull black Ð adding vinyl
shampoo, if necessary. Do not allow
moisture to soak through the seats or
headliner. Never use solvents such as
lacquer thinner, heavy-duty grease
remover, fuels, or similar substances.
Use a soft, clean cloth to wipe off the
clear covers of the instruments, using
methylated spirits with distilled water as
a cleaning solvent, if necessary, at a
mixing ratio of 1:1.Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
The safety belts should be cleaned with
a mild soap and water solution without
being removed from the vehicle. Never
attempt chemical or dry cleaning, as
damage to the belt fabric could result.
After cleaning, never allow the inertia
reel to retract the belts until they are
completely dry. Dirty safety belts
prevent the inertia reel mechanism from
retracting the strap properly, thus
constituting a safety hazard.
Heavily soiled floor carpets and mats
*
can be cleaned with an interior cleaner.
The floor mats can be removed from
the vehicle for cleaning.
Clean aluminum surfaces with water
and, if necessary, with a mild soap.
Never use solvents such as lacquer
thinner, heavy-duty grease remover,
fuels, or similar substances.
Use only a wet cloth to clean painted
inner parts. Dry them afterwards with a
soft cloth.
Use the cleaning and car-care
products available at your BMW
center.<

Airbags 1 Front airbags on the driver and
passenger side
2 Side airbags on the driver and front
passenger sideImportant safety notices
Do not attempt to remove the gas
generators of the airbag restraint
system from the vehicle. Testing and
servicing are to be performed only by
trained technicians.
In the event of a malfunction, deactiva-
tion, or triggered actuation (as a
response to an accident) of the airbag
restraint system, consult your BMW
center for repairs or service operations.
520de021
Do not modifiy or tamper with either the
wiring or the individual components in
the airbag system. These include the
padded steering wheel hub, the instru-
ment panel, and the side trim panels of
the doors. Never apply adhesive mate-
rials to these components or cover or
modify them in any way. Do not remove
or dismantle the steering wheel your-
self.
To ensure compliance with applicable
safety regulations, have a BMW center
dispose of airbag generators.
Unprofessional attempts to service the
system could lead to failure in an emer-
gency or undesired airbag activation,
either of which could result in personal
injury.<

Vehicle storage
If the vehicle is to be stored for
more than three months, ensure
that the following service operations
are carried out first.<
Preparations for storageHave your BMW center perform the
following procedures:
1. Clean and apply a rust proofing
agent or other treatment to the
engine, engine compartment, under-
carriage, axles and major compo-
nents in accordance with approved
repair procedures. Wash the vehicle,
clean the interior and treat painted
and chromed parts. Clean the
weather-stripping around the hood,
luggage compartment and doors
2. Change engine oil and oil filter at
operating temperature. As an addi-
tional corrosion protection measure,
an anticorrosive agent can be added
to the engine in accordance with the
manufacturer's instructions
3. Check the coolant level and concen-
tration and top off if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top off
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 vehicle1. 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 area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not engage
the parking brake
3. Remove the battery, charge it
completely and store it in a cool (but
frost-free) room
4. Remove the hardtop and store it
separately, refer to page 96
5. Close the convertible top.
During storageRecharge a battery that has been taken
out of the vehicle every six months. If it
is not recharged, it will not be service-
able. 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 138.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement, if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).

Changing a wheel Safety tiresYour BMW Z8 roadster is equipped
with safety tires.
The safety tires are made of self-
supporting tires mounted on specially-
designed wheel rims. Special reinforce-
ment elements support the sidewalls in
the event of pressure loss. Although tire
performance is then restricted, the
vehicle can still be driven on the
deflated tire for a limited distance. Your
vehicle is equipped with a tire pressure
monitor that signals you in case of a flat
tire.
In the event of a flat tireThe red indicator lamp on the instru-
ment panel will flash in the event of a
flat tire. In addition, a gong will sound.
Refer to page 67.
Carefully reduce speed to less than
50 mph (80 km/h), avoiding any hard
braking or steering maneuvers while
doing so.
You will still be able to drive approx.
155 miles (250 km) on your safety tire,
until you can get to a safe place to park,
a gas station, or to your nearest BMW
center. Under minimum vehicle loading,
it could conceivably last more than
155 miles (250 km).
If you cannot immediately determine
which tire is defective just by looking
at it, then check the tire pressure in all
four tires.Have your BMW center replace
your tires. For safety reasons, do
not have safety tires repaired. Your
BMW center has been trained to work
with the safety tires and is equipped
with the necessary special tools.<
If necessary, please have your
BMW center switch the tires on
your vehicle from summer to winter
tires, or the reverse.<
