Coolant
Checking coolant level
e Important:
Always keep the fluid level
above the minimum mark. Add
coolant only when the engine is
cold.
 Place the BMW C1 on its
stand
– after making sure that the
ground is level and firm
 Open the seat
 Check coolant level in expan-
sion tank:
MAX Maximum level
MIN Minimum level
( ) Figure in bracketsbpage number for
description
e Important:
Never overfill the expansion
tank.
 Top up the coolant if neces-
sary (Service and Technical
Booklet
b 24)
 Close the seat
\f Note:
If the expansion tank is full and
coolant temperature is high (as
indicated by red warning light
\b
b 11) or coolant consumption
is excessive, consult a special-
ist workshop, preferably an au-
thorised BMW dealer.

Engine oil
Winter operation
\f Note:
If temperatures under 10 °C per-
sist for lengthy periods and dur-
ing the cold season of the year,
use SAE 5 W-40 engine oil.

Checking the oil level
e Important:
The red
p (b 11) engine oil
pressure warning light indicates
that the oil pump's delivery rate
is too low: it is not an oil level
indicator. The warning light
goes out after 1-2 seconds,
once oil pressure has built up –
the red
p engine oil pressure
warning light must remain off at
all times when the vehicle is in
motion. Check the oil level reg-
ularly, each time that fuel is
added (or at least every second
time). Always check engine oil
level with the engine at its regu-
lar operating temperature. With
the engine at its regular operat-
ing temperature, wait
approx. 1 minute for the oil to
drain back into the sump.
Checking the oil level just after
the engine has been run or
when it is not properly warm will
falsify the reading and could
lead to the engine being operat-
ed with the wrong quantity of
oil.

Safety check
e Important:
To avoid damage to the engine:
– never exceed the maximum
oil level.
– always keep the oil level
above the minimum mark.
 Wait one minute after switch-
ing off and check engine oil
level with the engine at regu-
lar operating temperature.
 Place the BMW C1 on its
stand
– make sure that the ground is
level and firm 
Unscrew and remove
dipstick 1, clean it and push it
back in to check the oil level
(do not screw in)
 Check oil level against lines
marked on dipstick:
MAX Maximum level
MIN Minimum level
The difference is equivalent to
approx. 0.2 litre (0.352 Imp.
pints)
 Add engine oil through filler
neck if necessary
 Reinstall the dipstick

Fuel
Refuelling
d Warning:
Fuel is flammable and explo-
sive. Do not smoke. Never
bring a naked flame near the
fuel tank.
Fuel expands when hot (for
instance if the fuel tank is in
the sun). When refuelling, in-
sert the pump nozzle fully into
the tank and release the trig-
ger as soon as the pump
shuts down automatically
(tank filled to capacity) (
b 33)
- fuel could escape if you
overfill the tank.
( ) Figure in bracketsbpage number for

e Important:
Note that fuel containing lead
will destroy the catalytic con-
verter.
Do not run the fuel tank dry or
you may damage the engine or
catalytic converter.

Safety check
Brakes
Checking brake pressure
d Warning:
Sudden changes in play or
spongy action of the hand-
brake lever indicate a fault in
the brake system.
Before riding off, therefore,
always check the resistance
of the front and rear brake
levers and test operation of
the brakes.
Do not ride your BMW C1 if
you have any doubts about
the safety of the brake sys-
tem.
Immediately seek the advice
of a specialist workshop,
preferably an authorised
BMW dealer.
Work on the
brake system

To ensure reliability have all
work on the brake systems
carried out by a specialist
workshop, preferably an au-
thorised BMW dealer.

Safety check
Brakes
Changing the brake fluid
d Warning:
Brake fluid is subject to
severe thermal loads, and
absorbs moisture from the
atmosphere.
Consequently, the brake fluid
must be changed regularly
(
bsee the Service and Tech-
nical Booklet Chapter 2) by a
specialist workshop, prefera-
bly an authorised
BMW dealer.

Checking the brake fluid
level
Gradual wear of the brake pads
causes the brake fluid level in
the reservoir to sink.
d Warning:
If brake fluid level in the fluid
reservoirs for the front or rear
brakes has dropped below
the MIN mark (
b 36-37), have
the brake system checked
without delay by a specialist
workshop, preferably an au-
thorised BMW dealer.
