The electrical circuit of the indicator light can
be checked by turning the key to “ ” (on). If
the indicator light does not come on initially
when the key is turned to “ ” (on), or if the
indicator light remains on, have a Yamaha
dealer check the electrical circuit.TIPSee page 4-12 for a detailed explanation of
this indicator light and how to set it. EBU35282Coolant temperature warning light “ ”
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
on, stop the vehicle as soon as it is safe to do
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
8-66.)
TIPThe coolant temperature warning light can be
checked by turning the key to “ ” (on). The
warning light should come on in purple briefly
(which confirms that both the blue and red in-
dicators are okay) and then go off. If the warn-
ing light does not come on at all, comes on in
red or blue, or if the warning light remains on,
have a Yamaha dealer check the vehicle. NOTICEECB02040
The engine may overheat if the vehicle is
overloaded. If this happens, reduce the

This warning light comes on when the key is
turned to “ ” (on), and then goes off once
the engine is started. If the warning light re-
mains on or comes on after the engine is
started, the EPS system may not be working
correctly. When this occurs, have a Yamaha
dealer check the EPS system.
The electrical circuit of the warning light can
be checked by turning the key to “ ” (on). If
the warning light does not come on, have a
Yamaha dealer check the electrical circuit.TIPIf the steering load is too heavy (e.g., exces-
sive steering use at slow speed or when op-
erating in deep mud, sand, or snow), the
power assist is reduced to protect the EPS
motor from overheating.

be protected against frost and corro-
sion. If water has been added to the
coolant, have a Yamaha dealer check
the antifreeze content of the coolant
as soon as possible, otherwise the ef-
fectiveness of the coolant will be re-
duced.

5. Install the reservoir cap.
6. Install the hood when finished servicingthe vehicle.TIPThe radiator fan automatically switches on
or off according to the temperature of the
coolant in the radiator.
If the engine overheats, see page 8-66 for
instructions.

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 recommende d 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.
