Low coolant temperature indicator light
The low coolant temperature indicator light 1 flashes
when the coolant temperature is low and informs the
rider that the snowmobile must be warmed up. After the
engine is started, warm it up until the indicator light goes
off.
The snowmobile can be operated normally after the indi-
cator light goes off.
NOTE:
When the low coolant temperature indicator light flashes,
the engine control system prevents the engine speed
from rising even if the throttle lever is pressed.
ESU00364
Coolant temperature warning indicator
If the engine overheats, the coolant temperature warning
indicator
1 and the warning light 2 come on. When this
occurs, stop the engine immediately and allow the
engine to cool down, and then check the coolant level in
the coolant reservoir. (See page 6-4.)
CAUTION:
@
Do not operate the engine if it overheats.

The coolant temperature warning indicator indicates a
malfunctioning sensor, disconnected coupler, broken
lead, or short circuit when detected by the self-diagnosis
device of the snowmobile.
The coolant temperature warning indicator and warning
light warn the rider of the above problems by flashing
continuously. (See the table below for the warning light
flash pattern.)
When this occurs, have a Yamaha dealer inspect the
snowmobile as soon as possible.
