329zStatus indicators

Residual braking function
activeGeneral warning light
lights up red.
ABS warning light
flashes four times per
second.
Without the assistance
of the ABS function, the
wheels could lock when the
brakes are applied hard. You
have to apply considerably
more force to the brake
levers to brake without
servo-assisted brakes. The
changed braking response
can cause accidents.
Avoid hard braking if possible.
Apply brakes in good time as
increased effort is required.
Only residual braking func-
tion is available in at least one
brake circuit.
You can continue to ride.
However, the ABS function and brake servo assistance
are not available.
Have the fault rectified as
soon as possible by a spe-
cialist workshop, preferably
an authorised BMW Motor-
rad dealer.
Brake fluid level in wheel
brake circuit too low General warning light
flashes red once per
second.
ABS warning light
flashes once per
second.
The ABS wheel brake
circuit is a closed sys-
tem whose fluid level cannot
be determined at the brake
fluid reservoirs.
Very badly worn brake pads
can also trigger the "Brake
fluid too low" warning. Checking brake-pad thick-
ness, front brakes ( 95)
Checking brake pad thick-
ness, rear brakes ( 96)
Worn brake pads can
lengthen stopping dis-
tances by a significant margin
and consequently cause acci-
dents.
Apply the brakes in good
time.
Worn brake pads can
damage the brake discs.
Think well ahead and brake
carefully; avoid severe brak-
ing.
Have worn brake pads re-
placed as soon as possible
by a specialist workshop,
preferably an authorised
BMW Motorrad dealer.
If the brake pads are not
badly worn, the brake system
332zStatus indicators

will have to be checked for
malfunctions and leaks.Switch off the ignition and
pull the brake lever, then
release it and depress the
brake pedal.
Check the following:
Brake pressure perceptible
at brake lever and at brake
pedal.
Brakes acting on both
wheels.
No visible signs of brake
fluid leaking.
There is a defect in the
brake system and it
could result in brake fade.
Apply the brakes in good
time.
If these criteria are satis-
fied, you can continue rid-
ing. Bear in mind, however,
that a loss of brake fluid that
cannot be detected might be the cause of the warn-
ing.
Have the fault rectified as
soon as possible by a spe-
cialist workshop, preferably
an authorised BMW Motor-
rad dealer.
If the function and leak check
reveals a fault: There is a defect in the
brake system and it
could result in accidents.
Do not continue your jour-
ney.

Notify a specialist work-
shop, preferably an author-
ised BMW Motorrad dealer.
ABS fault General warning light
flashes red four times
per second. ABS warning light
flashes four times per
second.
There are at least two faults
in the brake system. Only the
residual braking function is
available in at least one brake
circuit and the fluid level in
the brake system is too low.
See the fault descriptions
above.

If the position of the
clutch fluid reservoir is
changed, air can enter the
clutch system.
Do not twist the handlebar
fitting or the handlebars. Attempting to adjust the
clutch lever while riding
the motorcycle can lead to
accidents.
Do not attempt to adjust the
clutch lever unless the motor-
cycle is at a standstill.

Changing the position of
the brake-fluid reservoir
can allow air to penetrate the

in this way is not covered by
the warranty.
Do not tamper with the
control unit of the electronic
engine-management
system.ChecklistUse the following checklist
to check important functions,
settings and wear limits be-
fore you ride off.Brakes

StartingSide standYou cannot start the motor-
cycle with the side stand ex-
tended and a gear engaged.
The engine will switch itself
off if you start it with the gear-
box in neutral and then en-
gage a gear before retracting
the side stand.GearboxYou can start the engine
when the gearbox is in neutral
or if you pull the clutch with a
gear engaged. Switch on the
ignition before you pull the clutch. When the gearbox is
in neutral, the green neutral
telltale light is on and the gear
indicator in the multifunction
display shows 0.
Starting the engine
If you switch on the ig-
nition while the brakes
are applied, then start the
engine and ride off immedi-
ately, the BMW Integral ABS
remains in residual braking
function mode. Self-diagnosis
is performed as soon as the
brake levers are in their fully
released positions for the first
time. Until this completes the
ABS function is not available;
the same applies to power
assistance for the brakes.
When you start the engine,
wait for the ABS to complete
its self-diagnosis.
Switch on the ignition.

If the brake disc is visible: Have the brake pads re-
placed by a specialist work-
shop, preferably an author-
ised BMW Motorrad dealer.Brake fluidChecking brake-fluid
level, front brakes
A low fluid level in the
brake reservoir can al-
low air to penetrate the brake
system. This significantly re-
duces braking efficiency.
Apply the brakes in good
time.
Make sure the ground is
level and firm and hold the
motorcycle upright.
Move the handlebars to the
straight-ahead position. with OA Centre stand:
Make sure the ground is
level and firm and place
the motorcycle on its centre
stand.
Move the handlebars to the

Check the brake fluid level
in reservoir 1.
The brake fluid level
in the reservoir does
not drop as the brake pads
wear. Brake fluid level, front

Do not permit the brake flu-
id level to drop.
Any drop in brake fluid level,
even if the level remains
above the MIN mark, is
indicative of a fault in the
brake system. Have the fault rectified as
soon as possible by a spe-
cialist workshop, preferably
an authorised BMW Motor-
rad dealer.
