Winter operationDriving on low-traction road
surfacesDo not activate the Sport Mode (refer to
page 64). Use smooth, gentle pressure
to control the accelerator pedal. Avoid
excessive engine speeds and shift to
the next higher gear at an early point.
Shift down into the next lowest gear
when approaching uphill or downhill
grades. Maintain an adequate distance
between yourself and the vehicle
ahead.BrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
The resulting increases in braking dis-
tance are considerable and should be
kept in mind at all times.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.If the ABS does not respond in a critical
braking situation and the wheels lock,
reduce the pressure on the brake pedal
until the wheels just start to roll again
while still maintaining enough force to
continue braking.
Then increase the pressure, reduce the
pressure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce braking distances while helping
you maintain steering control.
You can always then attempt to steer
around hazards after you have reduced
pressure on the brake pedal.
Do not shift down on slick road
surfaces if you want to decelerate.
Doing so could cause the wheels to
lose traction and skid, thus resulting in
the loss of vehicle control.<
Depress the clutch during hard
braking on road surfaces that pro-
vide only poor or uneven traction.<
Skid control Depress the clutch and release the
accelerator pedal. Countersteer care-
fully and attempt to regain control of the
vehicle.ParkingEngage first or reverse gear. Depending
on the steepness of the incline, you can
apply the parking brake as well. In order
to prevent the parking brake pads from
locking due to frost or corrosion, dry
them by gently applying the parking
brake as the vehicle is coming to a stop.
Make sure that following traffic is not
endangered.
The brake lamps do not come
on when the parking brake is
engaged.<

Coolant Brake fluidAdding coolant Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must fall within
the blue zone. If it is not, there is a
danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open
2 If the coolant is low, slowly add cool-
ant until the correct level is reached Ð
do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are
required.
Replace the coolant every three years.If the brake warning lamp comes on
and the parking brake has been re-
leased:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
For adding brake fluid or for determin-
ing and correcting the cause of brake
fluid loss, consult your BMW center.
Your BMW center is familiar with the
specifications for factory-approved
brake fluids (DOT 4).
Brake fluid loss can increase brake
pedal travel. For this type of situation,
refer to the notes on page 89.
520de093
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability 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 toxic and eats away the
vehicle's paintwork. You should always
store it in its original container and in a
location that is inaccessible to children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the "MAX"
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of brake fluid.<

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 dur-
ing or immediately after exposure to
strong sunlight.
In order to protect your convertible top,
do not have any special waxing pro-
gram done to 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 sur-
face. Inadequate distance and exces-
sive pressure can damage or weaken
the finish, making it more susceptible to
further damage. In addition, 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 vehicle

118n
Caring for your vehicleCaring for the vehicle finish Regular washing is a preventive mea-
sure against long-term effects from
substances that are harmful to the vehi-
cle's finish, especially if you drive your
vehicle in areas with high levels of air
pollution or natural contaminants (tree
resins, pollen).
Nevertheless, you should immediately
remove especially aggressive sub-
stances. Failure to do so can lead to
changes in the paint's chemical struc-
ture or to discoloration. Gasoline spilled
during refueling, oil, grease, brake fluid
and bird droppings should always be
cleaned up immediately.
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use clean-
ing fluid or alcohol and 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 available at your BMW
center.<
Waxing your vehicle Protect 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 available at your BMW
center.<
Repairing the paint You can touch up small areas of paint
damage with a BMW spray paint or a
BMW touchup stick.
The color code of your vehicle is pro-
vided 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).
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.

Storing your vehicle
If you plan on parking the vehicle
for more than three months,
please adhere the maintenance opera-
tions described below.<
Preparations for storageHave your BMW center perform the
following procedures:
1 Clean and apply a rustproofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in accor-
dance with approved repair proce-
dures. 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 op-
erating temperature. As an additional
corrosion protection measure, an an-
ticorrosive agent can be added to the
engine in accordance with the manu-
facturer'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 pre-
vent the formation of condensation
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 com-
pletely and store it in a cool (but
frost-free) room
4 Remove the hardtop and store it
separately, refer to page 95
5 Close the convertible top.During storageRecharge a battery that has been taken
out of the car 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 136.
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).

Lamps and bulbs The lamps and bulbs make essential
contributions to the safety of your vehi-
cle. Therefore, comply fully with the fol-
lowing instructions during bulb replace-
ment. If you are not familiar with any of
the procedures, consult your BMW
center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar material,
or hold the bulb by its metallic base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the electri-
cal system, switch off the electri-
cal accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage, com-
ply with any instructions provided by
the bulb manufacturer.<
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.<
Xenon lamps

The main headlamps for your BMW
Z8 roadster have been designed using
xenon-light technology. The service life
of these bulbs is very long and the
probability of a failure is very low, pro-
vided that they are not switched on and
off an unusual number of times.
Should a lamp ever fail, however,
please contact your BMW center for
assistance.
Because of the extremely high
voltages involved, any work on the
lighting system should be performed
only by authorized technicians. Failure
to comply with this creates a risk of
fatal injury.<
Neon lampsThe front turn signal indicators (side
marker lamps), the rear turn signal indi-
cators, the rear and brake lamps, as
well as the high-mount brake lamp, are
of neon-light technology. The service
life for these lamps is very high and the
likelihood of failure very minimal.
Should a lamp ever fail, however,
please contact your BMW center for
assistance.

Towing
Avoid "off-center" towing. Be sure
that the tow rope is pulled tightly
when the towing vehicle begins to
move.<
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-startingFor instructions on jump starting, refer
to page 143.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle1 Put the manual-shift gear lever in
neutral
2 Towing speed:
Max. 45 mph (70 km/h)
3 Towing distance:
Max. 95 miles (150 km)
4 Leave the ignition key at position 1 to
ensure that the brake lamps, turn sig-
nals, horn and windshield wipers
remain operative, and to prevent the
steering lock detent from engaging
5 Switch on the hazard-warning system
(comply with country-specific regula-
tions).
Find some means of identifying the
vehicle in tow, e. g. place a sign or
warning triangle in the rear window.
Make sure that the ignition key re-
mains in position 1 even when the
electrical system has failed to prevent
the steering lock from engaging. The
steering and brakes are without power
assist when the engine is not running.
This means that increased effort is
required for steering and braking.<
Towing with a commercial tow
truck>Do not tow with sling-type equipment
>Use a wheel lift or flat bed equipment
>Please comply with applicable towing
laws.
Never allow passengers to ride in a
towed vehicle for any reason.
Never attach tie-down hooks, chains,
straps, or tow hooks to the tie rods, con-
trol arms, or any other part of the vehicle
suspension. If you do so, severe dam-
age will occur to these components.<520us014

Highly sensitive sensors monitor the
number of revolutions of the wheels,
steering angle, lateral acceleration,
brake pressure and the movement
of the vehicle around its vertical axis.
If differences in wheel speed should
occur, the system will recognize the
danger this loss of traction causes and
reduce the drive torque going to the
wheels. The system will also apply the
brakes specifically to the rear wheels,
if necessary.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion and compares it with an ideal con-
dition that is calculated from the sen-
sor's signals. If differences such as
under- or oversteering should occur,
DSC will stabilize the vehicle in frac-
tions of a second by reducing engine
power output, applying the brakes to
individual rear wheels Ð and to specific
front wheels, too, if necessary. As a
result, dangerous skids can be pre-
vented even as they are beginning.You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and vehicle stability.
The braking intervention may be
accompanied by sounds specific to
the system.
The safety belt tensioner responds to
severe frontal collisions by tightening
the belt to ensure that occupants
remain firmly positioned in their seats.
A gas-pressure system retracts the
buckle assembly to tension the shoul-
der and lap belts within fractions of a
second. This reduces the tendency to
slide under the lap belt.
