2002 BMW Z3 engine coolant

126n
Coolant Brake fluid To add coolantWait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be
located in the blue field; otherwise,
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
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 regularly. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).If the warning lamp for the brake
hydraulic system comes on:
The brake fluid level is too low, refer
also to the instructions on page 104.
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 may result in extended
brake pedal travel. If this occurs, refer
to the notes on page 104.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the operating safety
and reliability 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).367de740

Airbags Storing your vehicle1 Front airbags on the driver and
passenger side
2 Side airbags on the driver and
passenger sideImportant safety notices
Do not attempt to remove the gas
generators of the airbag restraint
system from the vehicle or to disas-
semble them.
Have inspection and service proce-
dures performed by specially-trained
personnel only.
If the airbag restraint system malfunc-
tions, is deactivated or triggered as a
response to an accident, have the
system repaired by a BMW center only.
367de730
Do not make modifications of any kind
to the individual components or system
wiring. These include the upholstered
covers on the steering wheel hub, in the
instrument panel and in the side trim
panels of the doors. Never apply adhe-
sive materials to these components or
cover or modify them in any way. Do
not attempt to disassemble the steering
wheel itself.
To ensure compliance with applicable
safety regulations, have the airbag
generators disposed of by a BMW
center only.
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.< If you intend to store the vehicle
for longer than three months, have
the maintenance operations described
on this page performed.<
Preparation for storageHave the following operations
performed by your BMW center:
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 rubber
seals around the hood, luggage
compartment and doors
2. Change the engine oil and oil filter
with the engine at operating temper-
ature. As an additional 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 up if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top up if
necessary
