We know that when a warning light appears on your dashboard, it can be daunting – especially if you are unsure what to do. We have created this simple guide to help you understand what each warning light on your new or used car means and what steps you need to take. It is important that you know how to respond to each warning light to reduce any additional damage to your vehicle and to ensure that your vehicle is safe. If you are unsure how to carry out an action or repair on your vehicle our car trained experts know your car better than anyone.
Red warning lights mean you should stop the car as soon as it is safe.

Green warning lights are for information only.
Servicing plans allow customers to fix the price of their vehicle's maintenance in advance - enabling customers to budget against future wear and tear or mechanical faults.
