A WARNING
-A highly explosive mixture of gases can form
when charging batteries. Only charge the
vehicle battery in well-vent ilated areas.
-A drained vehicle battery can freeze at tem­
peratures around 32 QF (0 QC). A frozen or
thawed vehicle battery must not be charged
and must not be used anymore. The battery
housing can crack and battery acid can leak
out if ice forms, which increases the risk of
an explosion and chemical burns. Contact an
Checking and Filling
authorized Audi dealer or authorized Audi
Service Facility for more information.
- Do not connect or disconnect the charging
cable while charging because this increases
the risk of an explosion.
@ Tips
- Only charge the vehicle battery through the
connections in the engine compartment.
- Read all of the manufacturer's instructions
for the charger before charging the vehicle
battery.
Windshield washer system
Fig. 272 E ngine compar tm ent: was her fluid re serv oir cap
The windshi eld washer fluid reservoir O contains
th e cleaning solution for the windshield and the
he adlight washer system*¢
page 324, fig. 26 7 .
The reservoir capacity can be found in
¢page 379.
To reduce th e risk of lime scal e deposits on the
spray no zzles, use clean water with low amounts
o f calcium. Alway s add window cleane r to the wa­
ter . When the outside temperatures are cold, an
anti -freezing agent should be added to the water
so that it does not freeze.
(D Note
-The concentration of ant i-freezing agent
must be adjusted to the vehicle operating
conditions in the respective climate . A con­
centration that is too high can lead to vehi-
cle damage.
- Never add radiator anti-freeze or other addi-
tives to the washer fluid. .,..

Emergency situations
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
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con 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-
372
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
r=:> poge 322.
([) 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.

sumption.
- Always observe environmental regu lations
when disposing of old engine o il, used brake
flu id, d irty engine coolant, spent batteries
or worn out tires .
- Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Mate­
rial -spec ial handling may apply, see

Therefore, the ava ilability of certain parts needed
for repair , restoration , or reconstruction wi ll be
restricted , or parts will be unava ilable, if the ve­
hicle is not repaired at an a uthorized Audi colli­
sion repair facility. This includes but is not limit­
ed to structura l parts which require specialized
training and equipment to restore their crash ­
worthiness back to the original NHTSA and IIHS performance.
Your vehicle incorporates the latest safety design
features ensuring a high standard of active and passive safety.
Consumer Inf ormation
This safety could be compromised by non-ap ­
proved changes to the vehicle. For this reason, if
parts have to be rep laced, please observe the fol­
lowing points when install ing additional accesso­
