• Inflate the tire to between 29 psi (200 kPA)
and 36 psi (250 kPA) and read the pressure on
the gauge.
• If this tire pressure is not reached, remove the
filler hose. Drive slowly approximately 33 feet (10 m) forward or in reverse so that the sealant
can be distributed in the tire. Pump up the tire
aga in ¢ ,&. .
A WARNING
-Read and follow the manufacturer's safety
precautions on the compressor and in the
instructions on the bottle of sea lant.
- If a tire pressure of 29 psi (200 kPA) cannot
reached after inflating for 6 minutes, then
the tire is too severely damaged. Do not
continue driving.
- If the tire cannot be repaired with the tire
sealant, see an authorized Audi dealer or au­

mobility kit within the driver's field of vision.
• Stop the vehicle after driving for about 10 mi­
nutes and check the tir e pressure .
• If the tire pressure is lower than 19 psi (130
kPA), then the tire is too severely damaged. Do
not continue driving.
A WARNING
Pay attention to the following after repairing
the tire:
- Do not drive faster than SO mph (80 km/h).
- Avoid hard acceleration, braking sharply,
and fast cornering .

Emergency situations
@ Tips
The discharged battery must be properly con·
nected to the vehicle's electrical system .
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negat ive g round cable to the negative ground
post of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

The procedure described below for connecting
jumper cables is intended to provide a jump start
for your vehicle.
Vehicle with discharged battery:
.. Set the parking brake and select the P (Park)
selector lever position.
284
.. Switch the ignition and all electrical equipment
off.
Connecting the positive cable (red) to the
positive terminal
.. Open the red cover on the positive terminal
<=:>fig. 209.
1. Secure one end of the positive cable (red) to
the ju mp start connection
(D c:> fig. 210 on
the vehicle to be started @.
2 . Secure the other end of the pos itive cable
(red) to the positive terminal @on the vehi·
cle battery prov iding the current @.
Connecting the negative cable (black ) to the
negative terminal
3 . Secure one end of the negative cable (black)
to the negative term inal @ on the vehicle
batte ry that is providing the current @.
4. Secure the other end of the negative cable
(black) to the jump start connection
@of the
vehicle to be started @.
Starting the engine
.,. First start the engine in the vehicle giving the
charge @ and let it run at idle .
.. Now start the engine in the vehicle with the
drained veh icle battery @.
.. If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approximately 30 seconds .
.. Once the engine with the drained vehicle bat·
tery has been started, remove the cables in the
reverse order from the way they were installed .
.. Close the red cover on the pos itive terminal.
The battery is vented to the outside to prevent
gases from enter ing the vehicle interior. Make
sure that the jumper clamps are well connected
with their
metal ports in full contact with the
battery termin als.
.&_ WARNING
To avoid serious personal injury and damage
to the vehicle, heed all warnings and instruc­
tions 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.

perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, test ing devices and other
equ ipment available to specially trained work­

formance, rel iability and safety of the veh icle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
veh icle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the ma intenance sc hedule may be a condition for
upho ld ing a possib le wa rranty claim made within
the warranty period.
Above all, operational safety can be adversely af­
fected, creating unnecessa ry risks fo r you and
your passenger.
If i n doubt about any servicing, have it done by
your author ized Audi dealer or any other properly

A WARNING
--
- Ser ious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when work ing
on the vehicle . Always follow commonly ac­
cepted safety practices and general com­ mon sense. Never risk pe rsonal inj ury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fu lly famil iar with these
or other proced ures with respect to the ve­
h icle, or are uncerta in how to pro ceed.
- Do not do any work without the proper tools
and eq uipment. Have the necessary wo rk
done by your authorized Audi dealer or an­
other proper ly equipped and qualified work­
shop.
- The engine compartment of any motor vehi ­
cle is a potentially hazardous area . Never
reach into the area around or touch the radi­
ator fan.
It is temperature controlled and
can switch on suddenly
-even when the en­
g ine is off . The radiator fan switches on au­
tomatically when the coolant reaches a cer­
tain tempe rature and will cont inue to run
until the coolant temperature d rops.
- Always sw itch off the ignition before anyone
gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work underneath
the vehicle. The jack suppl ied with the veh i­
cle is no t adequate for this pu rpose and
could collapse caus ing serious personal in­
