Coolant temperature gauge
The coolant temperature gauge shows engine coolant temperature
with the coolant temperature display. When the segment begins to
move above the C (Cold) display, the engine is warm enough for the
SXS to be ridden. When the coolant temperature is low, the coolant
temperature gauge will display "Lo". The normal operating
temperature range is within the section between the H and C displays.

If all sections of the coolant temperature gauge, including segment
H and high coolant temperature indicator are on (automatically
appears in the display), stop the engine and check the reserve tank
coolant level.
Read pages 246 – 247 and do not drive the SXS until the problem
has been corrected.
NOTICE
Continuing to ride with an overheated engine can cause serious
engine damage.
