1. Learn your owner’s manual.
Knowing where to find information quickly can help in identifying causes when trouble arises. Beyond knowing the make and model of your vehicle, it also helps to have the specific trim level on hand for the service technician, as that often identifies the engine size and configuration, transmission and other included features that vary across the model line. Be aware of your exterior paint and interior color codes in case body or upholstery repair is necessary. Keep your vehicle identification number (VIN) available, as this code will likely be required when scheduling service.
