2. Attach your Pokéwalker to your Nintendo DS or DSi.
3. Select "Pokéwalker" from the main menu.
4. Select "Walk Mode" or "Run Mode."
5. Walk or run with your Pokéwalker.
As you walk or run, your Pokémon will earn experience points (EXP). When your Pokémon earns enough EXP, it will level up.
Here are some tips for leveling up your Pokémon on the Pokéwalker:
* Use the Pokéwalker regularly. The more you walk or run with your Pokéwalker, the more EXP your Pokémon will earn.
* Walk or run in areas with a lot of Pokémon. The more Pokémon you encounter, the more EXP your Pokémon will earn.
* Use the Exp. Share item. The Exp. Share item will allow your entire party of Pokémon to earn EXP, even if they are not in battle.
* Take advantage of the Pokéwalker's features. The Pokéwalker has a number of features that can help you level up your Pokémon, such as the "Walk Marathon" feature and the "Friend Safari" feature.
