  1. I will be glad to be getting a professional guide and update on the best way of handling and given the best modern professional base standards on all Toyota cars.

    Thanks

  2. I travel with a Lexus es 350 and each time I put on the A/C and drove a little distance it usually triggers the traction control and check engine light on and also sometimes doesn’t detect the remote for tumb starting but once I hit the remote on an object the green light for starting comes up.

    Pls kindly clear the air on this.. Thanks
