Status indicators222
Electronic immobiliser
(EWS)
EWS symbol is
displayed.
The key being used is not
authorised for starting, or
communication between the
key and engine electronics is
disrupted.
• Remove any other vehicle
keys located near the igni-
tion key (
b 30)
.
• Use the replacement key.
• It is best to have the defec-
tive key replaced by an
authorised BMW motorcycle
dealer (
b 32).
Fuel reserve
General warning light
lights up yellow.
Fuel reserve symbol is
displayed and flashes
10 times.The fuel tank contains a fuel
reserve of a maximum of
4 litres. The Tripmaster indi-
cates the estimated residual
operating range (
b 34).
Lack of fuel could result
in the engine cutting out
unexpectedly and this could
therefore cause a dangerous
road situation.
Do not run the fuel tank dry.c
A lack of fuel could result
in misfiring and this in
turn could damage the catalyt-
ic converter.
Do not run the fuel tank dry.c
•Refuel.
Coolant temperature
General warning light
lights up red.
Coolant temperature
indicator flashes 10 times.
Coolant temperature too high.
Continuing to ride when
the engine is overheated
could result in engine damage.
It is essential that the
measures given below are
observed.c
• Check coolant level, top up if
necessary.
• If possible, ride in the part-
load range to cool down the
engine.
• In traffic jams, switch off the
engine, but keep the ignition
on so that the radiator fan
continues to operate.

223Status indicators
Engine electronics
General warning light
lights up yellow.
Engine electronics
symbol is displayed.
Fault in the engine electronics.
In exceptional cases, the
engine stops and can no
longer be started. Otherwise,
the engine runs in emergency
operating mode.
You can continue to ride, but
bear in mind that the usual
engine output is not available.
• Have the fault remedied as
soon as possible by a spe-
cialist workshop, preferably
an authorised BMW motor-
cycle dealer.
Engine oil pressure
General warning light lights
up red.
Engine oil pressure symbol
is displayed.
Insufficient engine oil pressure.
The "engine oil pressure" warn-
ing indicates that there is no oil
pressure or that the oil pressure
in the lubricating oil circuit is too
low; under no circumstances is it
to be regarded as fulfilling the
function of an oil gauge. Once
the oil pressure has built up
1 – 2 seconds after the engine
start, the warning indicator must
go out.
If the "engine oil pressure" warn-
ing is displayed while the motor-
cycle is being ridden, take
account of the traffic situation
and:• Disengage the gear.
• Press the kill switch.
•Bring the motorcycle safely
to a halt.
• Check the engine oil level.
Alongside an insufficient
engine oil level, other
problems in the engine can
lead to the "engine oil pres-
sure" warning. Continuing to
ride in these cases can cause
engine damage.
If the "engine oil pressure"
warning is issued, do not con-
tinue to ride, even though the
engine oil level might be
correct.c
• Have the fault remedied by a
specialist workshop, prefer-
ably an authorised
BMW motorcycle dealer.

Status indicators224
Battery charge current
General warning light
lights up red.
Battery charge current
symbol is displayed.
The battery is no longer being
charged. You can only con-
tinue to ride until the battery is
discharged.
A discharged battery
could result in the engine
cutting out unexpectedly and
this could therefore cause a
dangerous road situation.
If possible, do not continue to
ride.c
• Have the fault remedied as
soon as possible by a spe-
cialist workshop, preferably
an authorised BMW motor-
cycle dealer.
Defective lamp

ure, there can be prob-
lems seeing and being seen.
Defective lamps should be
replaced as soon as possi-
ble.c

Electronic immobiliserThe electronic immobiliser
helps protect your BMW
motorcycle from theft, and this
enhanced security is at your
disposal without any need for
you to set parameters or acti-
vate additional systems. The
engine of a motorcycle fitted
with this electronic immobiliser
can only be started with the
keys that belong to the vehi-
cle. You can also have your
authorised BMW motorcycle
dealer bar individual keys, for
example if a particular key
goes missing. The engine can-
not be started with a key that
has been barred.
