Oil level/coolant temperature indica-
tor light “ ”
This indicator light has two functions.l
The light will come on and symbol
“ ” will flash if the engine oil lev-
el is low. If this symbol flashes,
stop the engine immediately and
fill it with oil to the specified level.
l
The light will come on and symbol
“ ” will flash if the coolant tem-
perature is too high. The following
chart shows the conditions of the
indicator light, symbol and tem-
perature display in accordance to
coolant temperature.
The light circuit can be checked by the
procedure on page 3-5.
EC000118
CAUTION:@ l
Do not run the motorcycle until
you know it has sufficient en-
gine oil.
l
Do not run the motorcycle if the
engine is overheated.
@NOTE:@ Even if the oil is fislled to the specified
level, the indicator light may flicker
when riding on a slope or during sud-
den acceleration or deceleration, but
this is normal. @

4-PRE-OPERATION CHECKSOwners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or
loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual in-
spection, you check the following points before each ride.
EAU00340
PRE-OPERATION CHECK LIST
ITEM CHECKS PAGE
Front brake
• Check operation, free play, fluid level and fluid leakage.
• Fill with DOT 4 brake fluid if necessary.6-25 ~ 6-28

ECA00005
CAUTION:@ The oil level/coolant temperature in-
dicator light and fuel indicator light
should come on for a few seconds
and then go off. If an indicator light
does not go off, refer to the corre-
sponding indicator light circuit
check in the “INSTRUMENT AND
CONTROL FUNCTIONS” section. @2. Shift the transmission into neutral.NOTE:@ When the transmission is in neutral, the
neutral indicator light should be on. If
the light does not come on, ask a
Yamaha dealer to inspect it. @3. Turn on the starter (choke) and
completely close the throttle grip.
4. Start the engine by pushing the
start switch.
NOTE:@ If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt. @5. After starting the engine, move the
starter (choke) to the halfway posi-
tion.NOTE:@ For maximum engine life, never accel-
erate hard with a cold engine! @6. After the engine is warm, turn off
the starter (choke) completely.NOTE:@ The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off. @
EAU01258

several minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.

Cooling system1. Check the coolant level in the res-
ervoir tank when the engine is cold
as the coolant level will vary with
engine temperature. The coolant
level should be between the maxi-
mum and minimum marks.2. If the level is low, remove the res-
ervoir tank cover by removing the
bolts.
3. Add coolant or distilled water to
raise it to the specified level.
4. Install the reservoir tank cover and
