Using your VTech Blaze the T - Rex Switch & Go Dinos toy is super easy. To switch between the T - Rex and car modes, just follow the natural movement of the toy parts. It's designed to be intuitive for kids. When you want to see the cool fire light projection and hear the sound effects, tilt Blaze's head back or press on the bumper. Remember to keep this toy away from water and other liquids as it's an electronic toy. Also, make sure small children don't put any parts in their mouths. For maintenance, use a dry cloth to wipe the toy clean. If the batteries run out, open the battery compartment at the bottom of the toy and replace them with new ones of the same type.
