Coolant Brake fluidAdding coolant To guard against the possibility of
scalding injuries, always wait until the
engine cools (temperature gauge
needle in blue sector) before
unscrewing the cap on the expansion
tank.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape, then continue
turning to remove.
2 If the coolant is low, slowly add
coolant 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
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every three years.The brake warning lamp comes on and
the parking brake has been released:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
For adding brake fluid or for deter-
mining 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 91.

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 attacks 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
disposal of brake fluid.<

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, 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
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 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).
