tem measures the current tire pressures and stores them as the new specified pressures.
~ If the changed tire pressures are not displayed
in the Infotainment system, drive the vehicle
for approximately 10 minutes so that the sen­
sor signal from the wheels is received again.
During this adaptation phase, --.·· is displayed
for the pressure and temperature and the tire
pressure monitoring system is only partially
available. It only provides a warning if one or
more tir e pressures is below the minimum per­
mitted specified pressure. If this is the case, the

Malfunctions
Applies to: vehicles with tire pressure monitoring syste m
-
If the Tire Pressure Monitoring System is not
avai lable, the
mm indicator light appears in the
driver information system. The
IE indicator light
also blinks for approximately one minutes each
time the ignition is switched on . The tire pressure
monitoring system cannot be selected in the In­
fotainment system. The fol lowing are examples
of situat ions that could cause a malfunction:
-If the message appears at the end of the adap­
tation phase, the system cannot detect the
wheels installed on the vehicle. This may resu lt
from one or more wheels being installed with­
out wheel sensors or with incompatible wheel
sensors.
-A wheel sensor or another component has
failed.
-Using snow cha ins can affect the function of
the system because of the shield ing effect of
the chains .
-The tire pressure monitoring system is not
available due to a malfunction.
-T ransmitters with the same frequency, such as
headphones or remote-control led dev ices, may
cause a temporary system malfunction due to
the strong electromagnetic field.
Wheels
T he m;i indicator light turns off once the Tire
Pressure Monitoring System is available again. If
you cannot correct the ma lfunction and the
m;i
indicator light stays on, drive immediately to an
authorized Audi dealer or authorized Audi Service
Facility to have the malfunction repaired.

" N .... 0 00 \.J ' Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING -
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases .
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-volt rating . The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah " rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c>page 193.
@ Note
- Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
( + ) terminals are connected.
247

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.
Use of jumper cables
Make sure to connect the jumper cable clamps in
exactly the order described below!

Wait for about 30 seconds and then try again.
• With engine running, remove jumper cables
from both veh icles in the exact
reverse order.
• Close the red cover on the pos itive terminal.
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 parts in full contact w ith the
battery terminals.
A 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.
- When connecting jumper cables, make sur e
that they cannot get caug ht in any moving
pa rts in the engine compartment.
