ABS warning lightThe ABS warning light 1 lights up
if the BMW Integral ABS develops
a fault (

81).
Warning light, general General warning light 2 lights up if
the BMW Integral ABS develops a
fault (

81), or if the tail light or
brake light is defective.
Low fuel levelWhen warning light 3 comes on,
there are still approximately
4 litres (0.9 gal) of fuel in the tank.
Engine oil pressureWarning light 4 goes out above
idle speed.
*n depending on national-market
specification
 Attention:
If warning light 4 comes on dur-
ing the journey, take the follow-
ing action as soon as traffic
conditions permit:
•Declutch
• Operate the kill switch
• Bring the motorcycle safely to
a halt
• Check engine oil level
(

30)
Top up with fresh oil if the oil
level is low. If the warning light
for engine oil pressure lights up
even though the oil level is cor-
rect, it is absolutely essential to
consult a specialist workshop,
preferably an authorised BMW
motorcycle dealer.

Brake system - with BMW Integral ABS
Sensitive electronic
control
It takes skill and sensitive con-
trol of the brakes to pull up
safely on a motorcycle. If the
front wheel brake locks and the
wheel skids, the necessary lon-
gitudinal and lateral stabilising
forces are lost, and a fall can
result.
For this reason, the rider sel-
dom makes full use of available
braking performance in an
emergency. BMW Integral ABS is the latest-
generation BMW ABS develop-
ment: by preventing both
wheels from locking and opti-
mising braking-force distribu-
tion by means of the integral
function, it offers much
improved braking performance
(

76). Full use is made of tech-
nical braking capacity to mini-
mise braking distances, even
when road conditions are poor.
When the motorcycle is ridden
in a straight line, the BMW Inte-
gral ABS is able to handle
emergency braking safely.

Extra safety reservesBut remember: the potentially
shorter braking distances
which BMW Integral ABS per-
mits must not be used as an
excuse for careless riding. ABS
is primarily a means of ensuring
a safety margin in genuine
emergencies.
– You have to familiarise your-self with the new, electroni-
cally assisted braking. Try the
brakes several times when
you take your motorcycle out
for the first time. Find out for
yourself how the brakes feel
– Never ride without due care
and attention, or assume that
good fortune will protect you
from your own foolhardiness
– Keep within the permitted
speed limits – Take care when cornering.
When you apply the brakes on
a corner, the motorcycle's
weight and momentum take
over and even BMW Integral
ABS is unable to counteract
their effects.

Brake system - with BMW Integral ABS
Partially integral brakes The integral brake function
interlinks the front and rear
brakes, so both wheels are
braked when you operate the
brake lever.
The electronic controller in the
BMW Integral ABS computes
the braking-force distribution
between front and rear wheels,
and applies the brakes
accordingly.
Braking-force distribution
depends on load and is recal-
culated every time the ABS
controller comes into action.
In this partially integral brake
configuration, the integral brak-
ing function is activated only
when you pull the handbrake
lever. The footbrake lever acts
only on the rear brake.
Brake boosterThe hydraulic pump in the BMW
Integral ABS actively boosts the
braking force acting on the
wheel when the brakes are
applied.
By boosting the braking force in
this way, the BMW Integral ABS
achieves higher braking effi-
ciency than standard brake
systems.
ABS - anti-lock brake
system
ABS prevents the wheels lock-
ing under heavy braking when
the motorcycle is travelling in a
straight line, thus contributing
significantly to road safety.

RESIDUAL BRAKING
FUNCTION
If the BMW Integral ABS develops
a fault, a RESIDUAL BRAKING
FUNCTION only is available in the
brake circuits in question.
The RESIDUAL BRAKING FUNC-
TION is the braking efficiency
without the hydraulic servo assist-
ance of the BMW Integral ABS.
Under these circumstances,
therefore, you must apply CON-
SIDERABLY higher pressure to
the brake levers in question in
order to apply the brakes, and
lever travel is longer.
When the RESIDUAL BRAKING
FUNCTION is active, the ABS
function is unavailable in the
brake system in question.
When the RESIDUAL BRAKING
FUNCTION is active, the integral
braking function is partially or
entirely unavailable.
 Warning:
When the RESIDUAL BRAKING
FUNCTION is active, maintain a
defensive riding style and pro-
ceed immediately to the near-
est specialist workshop,
preferably an authorised BMW
motorcycle dealer.

Note:
When the RESIDUAL BRAKING
FUNCTION for the front brake is
active, it is advisable to set ad-
juster A (

35) of the handbrake
lever to position 4.
The RESIDUAL BRAKING
FUNCTION is active under the
following circumstances:
– Ignition off
– Before and during self- diagnosis (

78)
– Fault in the BMW Integral ABS (

81)

Note:
When the RESIDUAL BRAKING
FUNCTION is active for both
brake circuits, the noise of the
pump is no longer audible when
you operate the brake levers.

Self-diagnosis with pull-
away test
The BMW Integral ABS performs
self-diagnosis and a pull-away
test to ensure its operability.
Self-diagnosis is performed auto-
matically when you switch on the
ignition.
 Warning:
Self-diagnosis is not performed
unless both brake levers are in
their fully released positions.
Only the RESIDUAL BRAKING
FUNCTION is available until
self-diagnosis is completed
(
77).
*n depending on national-market
specification
• Release the brake levers, if necessary
• Switch on the ignition
Initially:
– ABS warning light 1:
Flashes at 4 Hz
– General warning light 2:
ON

Self-diagnosis is in
progress
Then:
– ABS warning light 1:
Flashes at 1 Hz
– General warning light 2:
OFF

Note:
Flashing at 1 Hz = 1 flash per

Note:
Starting on gradients:
Always switch on the ignition
with gear engaged, clutch lever
released and both brake levers
released.
Self-diagnosis cannot be per-
formed if you do not follow this
procedure.
When self-diagnosis com-
pletes, apply the brakes, disen-
gage the clutch, and start the
engine.

 Warning:
If the BMW Integral ABS fails
in both brake circuits, a RE-
SIDUAL BRAKING FUNCTION
only is available (
77).
 Warning:
If the RESIDUAL BRAKING
FUNCTION (

77) is active,
maintain a defensive riding
style and proceed immediate-
ly to a specialist workshop,
preferably an authorised BMW
motorcycle dealer.
*n depending on national-market
specification
 Warning:
If there is a fault in the ABS
system, the reserves of safety
normally afforded by ABS are
not available until the defect
has been put right.
There is a risk of dropping the
motorcycle if the brakes are
applied too hard and the
wheels lock or the rear wheel
lifts clear of the ground as a
r e su l t o f a h i g h le v e l o f t yr e ad -
hesion. Have the defect recti-
fied immediately by a
specialist workshop, prefera-
bly an authorised
BMW motorcycle dealer.
