carro nao anda para frente com botoes.

Galera estou desenvolvendo um projeto de carro para android, e quando adicionei os botoes de um assets do propio unity o carro nao anda para frente. Eu usei o script desse mesmo assets quem vem no unity, mas o carro nao anda para frente apenas para tras e vira as rodas. quem puder ajudar agradeço.

Qual o nome do Script?

 então eu peguei esse script no propio unity, fui la em assets e import package e vehicles, depois fui la pastas e peguei os scripts do carro e coloquei no meu tudo certo, depois peguei os botoes para android, mas quando aperto play o carro so anda para tras e vira as rodas

esse é o script:

cara eu mexi em uns negocios aqui e ele andou pra frente mas bem devagar e pra tras ele ia bem rapido. agora ele parou de ir pra frente dnv, pode me ajudar a resolver ?

o Problema deve tá nos botões

entao é bom eu criar uns novos ?
