be sure your vehicle won't move, even when

ice or sand without damaging your transaxle, see If
You Are Stuck: In Sand, Mud, Ice or Snow

Shifting into a drive gear while your engine is
"racing" (running at high speed) is dangerous.
Unless your foot is firmly on the brake pedal,
your vehicle could move very rapidly. You
