Polaris 120 XC SP Youth Universal Owner's Safety And Maintenance Manual page 38

Snow and ice buildup in the underhood area can inter-
fere with the steering.
Before allowing your child to drive the machine, be sure that ice
and snow are not interfering with the steering. Manually turn the
skis to the left and right. If difficulty is encountered, check for
ice and snow buildup which may be obstructing the steering
linkage.
Hard Packed Snow
Steering and braking control are substantially reduced when
operating on on hard surfaces, hard-packed snow, or icy surfaces.
Teach your child to reduce speed as required to maintain control in all
driving conditions. If necessary, maximum speed may be regulated by
using the procedure outlined on page A- -31.
