• You need to hold the door closed and press the button above it to lock the door. Do not try to open the door during the heating or cooling cycle when it is locked.

• If you hear “Error,” ask an adult to unplug Car Maker from the wall, wait ten seconds and then plug it back in to reset. Car Maker may automatically go into the cooling cycle. Do not unplug during this time. If you continue to hear “Error” after multiple resets, this may be an indication of a mechanical problem with the door switch; please contact Consumer Services via service.mattel.com for assistance.

• Yes, for best results, allow the wax to cool for a few minutes before opening the mold. Twist the mold slightly (as you would an ice cube tray) to break the wax free. You can also run the mold under cold water, which will help speed up the cooling process. If the car body is wet, be sure to dry it completely before applying labels. Remove car body from the mold within 10 minutes. If the body is left in the mold for any longer, the wax may begin to crack.

• Excess wax on the car body can be easily trimmed by hand or with the supplied design tool.

• If you cannot insert or remove the mold, locate the tabs on both sides of Car Maker (underneath handle), push them up and try again.

• If you have inserted different colored wax sticks next to each other, you may get some color blending (in which the wax from the two adjacent sticks mix when creating the car body).

Push the handle on the far right counterclockwise all the way to the ground and the car platform will tip forward, allowing your car to roll out.

• In order to create a solid one-colored car body, you must insert multiple wax sticks of the same color next to each other.

• If your car body came out only partially completed, see instructional video or try the following:
• Ensure you are inserting enough wax sticks into the machine and they are positioned next to each other in the proper alignment (point side down).  Remember, it’s normal for one of the wax sticks to protrude from the top.
• Ensure the handle is pulled all the way down in one continuous motion and the injection is completed within 2-3 seconds until you hear “Complete.”

• Ensure the mold has been thoroughly cleaned before starting your cycle.
