engine overheat BMW MOTORRAD G 650 XCHALLENGE 2007 Rider's Manual (in English)

Fuel down to reserve
Warning light for fuel down
to reserve lights up.
Lack of fuel can result in
the engine misfiring and
cutting out unexpectedly. Mis-
firing can damage the catalytic
converter; a hazardous situation
can result if the engine cuts out
unexpectedly.
Do not run the fuel tank dry.
Possible cause: The fuel tank
contains no more than the re-
serve quantity of fuel.

Refuelling ( 52)Insufficient engine oil
pressure
Warning light for oil pres-
sure shows.
The oil pressure in the lube-oil
system is too low. Stop immedi-
ately and switch off the engine if
the warning light shows.
The insufficient oil pres-
sure warning does not fulfil
the function of an oil gauge. The
only way of checking whether
the oil level is correct is to check
with the oil dipstick.
Possible cause: Engine-oil level
too low.
Check the engine oil level
( 65)
If the oil level is too low:
Top up the engine oil ( 67)
If the engine oil level is correct:
Riding when engine-oil
pressure is low can result
in engine damage.Do not continue your journey.
Have the fault rectified as
quickly as possible by a
specialist workshop, preferably
an authorised BMW Motorrad
dealer.
Coolant temperature too high
Warning light for coolant
temperature shows.
Continuing to ride when the
engine is overheated could
result in engine damage.
You must comply with the in-
structions below.
Possible cause: Coolant level too
low.
Check the coolant level ( 71)
If the coolant level is too low:
Topping up coolant ( 72)
Possible cause: Radiator fan de-
fective.
322zStatus indicators

Catalytic converterIf misfiring causes unburned fuel
to enter the catalytic converter,
there is a danger of overheating
and damage.
For this reason, observe the fol-
lowing points:
Do not run the fuel tank dry.
Do not attempt to start or run
the engine with a spark-plug
cap disconnected.
Stop the engine immediately if
it misfires.
Use only unleaded fuel.
Comply with all specified main-
tenance intervals.
Unburned fuel will destroy
the catalytic converter.
Note the points listed for protec-
tion of the catalytic converter.
Risk of fireTemperatures at the exhaust are
high.
Flammable materials (e.g.
hay, leaves, grass, clothing
and luggage, etc.) could ignite
if allowed to come into contact
with the hot exhaust pipe.
Do not permit flammable materi-
als to come into contact with the
hot exhaust system.
Cooling would be
inadequate if the engine
were allowed to idle for a lengthy
period with the motorcycle at
a standstill: overheating would
result. In extreme cases, the
motorcycle could catch fire.
Do not allow the engine to idle
unnecessarily. Ride away imme-
diately after starting the engine.
Tampering with the
control unit of the
electronic engine-
management system
Tampering with the engine
control unit can damage
the motorcycle and cause acci-
dents.
Do not tamper with the engine
control unit.
Tampering with the engine
control unit can result in
mechanical loads that the mo-
torcycle's components are not
designed to withstand. Damage
caused in this way is not covered
by the warranty.
Do not tamper with the engine
control unit.

pads more frequently and replace
the brake pads in good time.Air pressure and damping
characteristics
The off-road settings for air
pressure in the Air Damping
System and the front and rear
shock-absorber damping char-
acteristics will impair the motor-
cycle's handling characteristics
on surfaced roads.
If you have been off-roading, re-
member to correct the air pres-
sure in the Air Damping System
and the shock-absorber damping
characteristics before you return
to surfaced roads.
Deactivatable ABS
OE
You can deactivate the BMW
Motorrad Integral ABS for off-
roading ( 33).
BrakesHow can stopping
distance be minimised?Each time the brakes are applied,
a load distribution shift takes
place with the load shifting for-
ward from the rear to the front
wheel. The sharper the motor-
cycle decelerates, the more load
is shifted to the front wheel. The
higher the wheel load, the more
braking force can be transmitted
without the wheel locking.
To optimise stopping distance,
apply the front brakes rapidly and
keep on increasing the force you
apply to the brake lever. This
makes the best possible use
of the dynamic increase in load
at the front wheel. Remember
to pull the clutch at the same
time. In the "panic braking situ-
ations" that are trained so fre-
quently braking force is applied
as rapidly as possible and withthe rider's full force applied to
the brake levers; under these cir-
cumstances the dynamic shift
in load distribution cannot keep
pace with the increase in de-
celeration and the tyres cannot
transmit the full braking force to
the surface of the road. ABS has
to intervene to keep the front
wheel from locking; this increases
stopping distance.
Descending mountain
passes
There is a danger of the
brakes fading if you use
only the rear brakes when des-
cending mountain passes. Under
extreme conditions, the brakes
could overheat and suffer severe
damage.
Use both front and rear brakes,
and make use of the engine's
braking effect as well.
