WARNING  
It is advisable to carry the wheel bolt adapter in the vehicle. The  
adapter is normally stored in the vehicle tool kit, underneath the  
towline anchorage. It should be put back there after use.  
• When it is discharged the battery can freeze at temperatures  
around 0°C. A frozen battery must first be thawed out before  
connecting the jump leads, as it could otherwise explode.  
The code number of the anti-theft wheel bolt is stamped on the front  
of the adapter. Your Audi dealer will need this number to replace the  
adapter if lost.  
• Please note the safety warnings referring to working in the  
engine compartment ⇒ page 221.

• The discharged battery must be properly connected to the  
vehicle's electrical system.  
Jump-starting  
• Switch off the car telephone if necessary. Details will be given in  
the manufacturer's instructions for the car telephone.  
Before starting the engine  
If necessary, the engine can be started by connecting it to  
the battery of another vehicle.  
If the engine should ever fail to start because of a discharged  
battery, the battery can be connected to the battery of another  
vehicle to start the engine. Suitable jump leads are required.  
Both batteries must be rated at 12 Volts. The capacity (Ah) of the  
booster battery should not be significantly lower than that of the  
discharged battery.
