Engine preheating system  
Fig. 114 In the front left bumper: Connection socket 2 for the engine preheating system.  
Please first read and note the introductory information and heed the WARNINGS  
Your vehicle may be equipped with an engine preheating system (engine preheater), which slowly  
warms the engine coolant using a heating element when the vehicle is parked. The included cable  
must be connected to a 120 Volt Ground Fault Circuit (GFI) protected outlet that is protected from  
water (in your garage, for instance). When the coolant is preheated, the engine reaches its operating  
temperature more quickly, uses less fuel, and produces less polluting emissions during the warm-up  
phase.  
Preheating the engine can take up to 3 hours depending on the temperature outside.  
Connecting the engine preheating system  
Use only the provided connecting cable, together with an appropriate extension cable if necessary.  
All cables and adapters that are used must not be damaged ⇒ꢀ  
.
Open the cover ⇒ꢀfig. 114 (1).  
Plug the connecting cable into the socket (2).  
Attach the connecting cable to an extension cable if necessary. Always use a 12 gauge or heavier  
heavy-duty extension cable that can be properly grounded to a three-prong Ground Fault Circuit (GFI)  
wall outlet and is not longer than 100 ft (30 meters).  
Plug the connecting cable or the extension cable into a 120 Volt Ground Fault Circuit (GFI) wall  
outlet that is properly protected against rain and other moisture. Never plug the preheater into a  
normal outlet regardless of whether the outlet is grounded or not.  
Always disconnect the connecting cable and close the cover (1) before starting the engine.  
WARNING  
Improper use of the engine preheating system may cause short circuits, fires, and serious or  
fatal personal injuries.  
Always connect the connecting cable to a 120 Volt Ground Fault Circuit (GFI) wall outlet.  
The outlet must be protected from water, moisture and other fluids.  
Never connect the engine preheating system to a conventional socket, regardless of  
whether the socket is protected or not.  
WARNING  
Using an outlet or power cables that are incorrect or damaged, using electrical appliances  
incorrectly, or ignoring safety precautions can result in short circuits, accidents, injuries, and  
life-threatening electrical shocks.  
Never use a damaged outlet or a damaged power cable.  
Always plug the preheating system into a 120 Volt Ground Fault Circuit (GFI) wall outlet  
that is properly protected against rain and other moisture.  
Always check the fuse protection of the 120 Volt power source before using the  
connecting cable.  
Always use a 12 gauge or heavier heavy-duty extension cable that can be properly  
grounded to a three-prong GFI outlet. The extension cable must not be longer than 100 ft  
(30 meters).  
Check the cables for damage before every use. Never use a damaged cable. Damaged  
cables must be replaced. See an authorized Volkswagen dealer or an authorized Volkswagen  
Service Facility.  
Only use the cables provided.  
Always remove the connecting cable before starting the engine.  
Never attempt to alter or repair cables or other electrical components.  
Never let plugs or connectors come into contact with water, moisture, or any other fluids.  
If the engine preheating system is used occasionally, test the GFI circuit breaker (Ground Fault  
Circuit Interrupter) once a month. Test it once a week if the system is used regularly.
