4. Connect the other end to the negative ground post of the
battery manager control unit located next to the battery.
Starting the engine
-Start the engine of the vehicle with the booster battery.
Run the engine at a moderate speed.
- Start engine with discharged vehicle battery in the usual
manner .
- If the engine fails to start: do not keep the starter
cranking for longer than 10 seconds. Wait for about 30
seconds and then try again.
- With engine running, remove jumper cables from both vehicles in the exact
reverse order.
The battery is vented to the outside to prevent gases from entering
the vehicle interior . Make sure that the jumper clamps are well
connected with their metal ports in full contact with the battery
terminals.
& WARNING
To avoid serious personal injury and damage to the vehicle, heed all warnings and instructions of the jumper cable manufacturer. If
in doubt, call for road service.
• Jumper cables must be long enough so that the vehicles do not
touch.
• When connecting jumper cables, make sure that they cannot
get caught in any moving parts in the engine compartment.
• Before you check anything in the engine compartment, always
read and heed all
WARNINGS ~ page 299, "Engine compartment".
0 Note
Improper hook -up of jumper cables can ruin the generator. •
Always connect POSITIVE(+) to POSITIVE(+), and NEGATIVE(-) to
NEGATIVE( -) ground post of the battery manager control unit.
• Check that all screw plugs on the battery cells are screwed in
firmly. If not, tighten plugs prior to connecting clamp on negative
battery terminal.
• Please note that the procedure for connecting a jumper cable as
described above applies specifically to the case of your vehicle
being jump started. When you are giving a jump start to another
vehicle, do not connect the negative(-) cable to the negative(-)
terminal on the discharged
battery @~ page 365, fig. 297. Instead,
securely connect the negative(-) cable to either a solid metal
component that is firmly bolted to the engine block or to the engine
block itself. If the battery that is being charged does not vent to the
outside, escaping battery gas could ignite and explode! •
Emergency towing with commercial
tow truck
General hints
Your Audi requires special handling for towing.
The following information is to be used by commercial tow truck
operators who know how to operate their equipment safely.
• Never tow your Audi, towing will cause damage to the engine
and transmission.
• Never wrap the safety chains or winch cables around the brake
lines.
• To prevent unnecessary damage, your Audi must be transported
with a flat bed truck.
• To load the vehicle on to the flat bed, use the towing loop found
in the vehicle tools and attach to the front or rear anchorage

&, WARNING (continued )
• The engine compartment of any motor vehicle is a potentially
hazardous area . Never reach into the area around or touch the
radiator fan . It is temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed . The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehi cle .
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle . The jack suppl ied with the
vehicle is not adequate for this purpose and could collapse causing serious personal injury .
• If you must work underneath the vehicle with the wheels on
the ground , always make sure the vehicle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in
"P " (Park position ) and the park brake is firmly
applied.
