The BAS or ESP BAS warning light on your dashboard can indicate any of several possible problems with your brake, wheel, or steering systems, and it could be dangerous to drive. Make sure your parking brake is off. If you can, check your vehicle’s master cylinder and make sure the brake fluid reaches the full level marker. If the light remains on after following these directions, or if you need help doing so, please contact an authorized Chrysler dealer or ASE-certified repair establishment and have the vehicle checked immediately.
