Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by "

l

" are tested for proper
functioning whenever the ignition key is
turned. They each light up once for
different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
You will see how to react to this in the
following section.

Red: stop immediately

Battery charge current

l

The battery is no longer being
charged. The alternator drive
belt is defective or there is a malfunc-
tion in the charging circuit of the alter-
nator. Please contact the nearest BMW
center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and
serious engine damage. If the drive belt
is defective, increased steering effort is
also required.

<


Engine oil pressure

l

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level and top off as
required. If the oil level is correct,
please contact the nearest BMW
center.
Do not continue driving, as the
engine could sustain serious
damage from inadequate lubrication.

<



Brake hydraulic system

l

The brake fluid level is too low.
Before driving further, be sure to
read the notes on pages 104 and 126.

Disc brakes Brake system Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead, decelerate
the vehicle with increased pressure on
the brake pedal (watch for following
traffic), release the pedal and then
repeat the brake application (staggered
braking). This staggered braking tech-
nique allows the brakes to cool in the
intervals between active braking
phases, preventing overheating and
ensuring that full braking capacity
remains available at all times.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in Neutral. Do not
coast with the engine switched off. The
engine provides no braking effect when
the clutch is depressed and there is no
power-assist for braking or steering
when the engine is not running.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Brake fluid level
The warning lamp for the
hydraulic brake system comes
on:
The brake fluid level is too low in
the reservoir (refer to page 126).
If the brake fluid level is too low
and brake pedal travel has become
noticeably longer, there may be a
defect in one of the two brake system's
hydraulic circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and braking distances may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
The warning lamp for the brake
pads comes on:
The brake pads have reached
their minimum pad thickness. Proceed
to the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads that BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle in the event of their use.<

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

Brake fluid Vehicle Identification Brake fluid is hazardous to health and
will damage the vehicle's paint. You
should always store it in its original
container and in a location which is
inaccessible to children. Avoid brake
fluid spills. Do not fill brake fluid beyond
the "MAX" level in the
reservoir. 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.<
The Vehicle Identification Number is
located in the engine compartment
below the windshield and on the top
of the instrument panel. 367us053

Storing your vehicle5. 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 vehicle for
storage1. Dry the parking brake and footbrake
by brake applications to prevent the
brake rotors and drums from
corroding
2. Park the vehicle in a covered, dry,
and well-ventilated room. Place the
transmission in 1st gear or set the
selector lever to the "P" position.
Chock the wheels to prevent the
vehicle from rolling if necessary. Do
not set the parking brake
3. Remove the battery, charge it
completely and store it in a cool (but
frost-free) room
Z3 roadster:
4. Remove the hardtop
* and store it
separately, refer to page 109
5. Close the convertible top.
During storageRecharge the battery 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 154.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement if necessary, refer to
the Service Manual.
