Whenever a light comes on your dashboard you should refer to your vehicle handbook as your first port of call to ensure that you follow any manufacturer’s recommendations and guidance.
However, as a general rule of thumb, if the warning light is red, you need to take immediate action and stop driving as soon as it’s safe to do so. If the warning light is yellow, the vehicle is safe to drive with extra care but should be driven as little as possible until a diagnostic check is undertaken by one of our branches. Ideally, once a yellow light illuminates, your next journey would be to one of our branches.
