VECI Label
WARNING: This page is about a different car, the 2007 Jeep Patriot and 2007 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
All models have a Vehicle Emission Control Information (VECI) Label. DaimlerChrysler permanently attaches the label in the engine compartment. It cannot be removed without defacing information and destroying the label.
The label contains the vehicle's emission specifications and vacuum hose routings. All hoses must be connected and routed according to the label.
