Well here's my shot at translating them to real english. Seems like they're talking about one of those large toy cars kids ride in, like the Power Wheels stuff.
-Inside contains small parts, do not put them in your mouth as they possess a choking hazard.
-To prevent injury, do not allow children 3 years of age and under to operate and do not operate while swimming. (You know, electrical componenents and all.)
-Don't use it on a road.... even I can't get what swimming has to do with a road.
-Do not wrap the antenna around your neck (yes they have to write this... just like they write "Caution: May be hot after heating")
-May have sharp edges, check on child frequently. (in other words, don't be a sh*tty parent. This seems to be a line stating that you need to check on your kid and they aren't responsible if the little idiot cuts themself on it.)
-If used in any other way, batteries may leak or explode. If this happens:
-Vehicle may short circuit and cause large electric current. Do not attempt to use if this occurs. Use it after the charge has drained.
-If contact with water occurs, do not use.
-Please do not dispose of in water or fire. the decomposition something something.
-Do not place in the vicinity of fire or heat and then attempt to use.
-When charging batteries, use only the correct charger.
-If used in any other way, batteries in the remote control may leak or explode.
-Do not attempt to charge the batteries in the remote control.
-Do not use old and new batteries together, and use only all of the same brand.
-um.....
-swim to take out the battery...... well thats what it looks like, I've done a better translating job than anyone else so far
-If battery acid comes in contact with the eyes, skin or clothes, flush with cold clean water.
-Do not close hair, clothes or fingers inside the vehicle (I'm assuming don't get them caught in the door) to prevent them from being tangled into the vehicle.
So there's only a couple lines I can't make out, like the swimming in the road or swimming to take out the battery
but that's about 98% of it.
