This warning light comes on when the coolant
temperature, and therefore the engine, is out-
side its normal operating temperature range.The warning light comes on in blue to inform
the driver that the vehicle should be warmed
up. After the engine is started, warm it up until
the warning light goes off.
The vehicle can be operated normally when
the warning light is off.
The warning light comes on in red when the
engine is overheating. If the red light comes

so and allow the engine to idle for about 10
minutes. If the warning light does not go off,
stop the engine and allow it to cool. (See page

dicators are okay) and then go off. If the warn-
ing light does not come on at all, comes on in

TIPThe radiator fan automatically switches on
or off according to the temperature of the
coolant in the radiator.
 If the engine overheats, see page 8-67 for
instructions. EBU32400Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.
EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine.

TIPService the air filters more frequently when
operating in wet or dusy environments. Whenever air filter maintenance is performed:
check the air inlet for obstructions and the
air filter case for dirt and foreign matter.
 check the air filter case check hoses for dirt
or water and clean as necessary.
 check the air filter cas e joints and the rub-
ber joints to and from the throttle body for
proper fit and sealing.
 tighten all fittings securely to avoid the pos-
sibility of unfiltered air entering the engine.NOTICEECB02270Never operate the engine with the air filter
element removed. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage. Additionally, the fuel injection system
would be affected, resulting in poor engine
performance and possible overheating.
Clean the primary air filter as follows.
1. Remove panel C (page 8-10).
2. Remove the air filter case cover by turn- ing the air filter case cover lock counter-
clockwise.TIPMake sure that the match mark on the cover
lock is aligned with the open match mark on
the air filter case cover.

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIPIf it is difficult to get the recommended coolant, tap water can be used temporarily, provided that
it is changed to the recommended coolant as soon as possible. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
