Electric power steering warning
indicator “EPS” (RS90P /
RS90PLT / RST90PGT)
The electric power steering warning indicator
comes on when the key is turned to the on po-
sition, and then goes off once the engine is
started. If the warning indicator remains 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.
TIP
If the steering load is too heavy (i.e., exces-
sive steering use when the snowmobile is
traveling at a slow speed), the power assist is
reduced to protect the EPS motor from over-
heating.

possible.
