& WARNING
Charging a battery can be dangerous.
- Always follow the operat ing instruct ions
provided by the battery charger manufactur­
er when charging your battery .
- Never charge a frozen ba ttery . It may ex­
plode because of gas trapped in the ice. A l­
low a frozen battery to thaw out first .
- Do not reuse batteries wh ich were frozen.
The battery housing may have cracked and
weakened when the battery froze .
- Charge the battery in a we ll ventilated area.
Keep away from open flame or electrical
spark. Do not smoke . Hydrogen gas generat­
ed by the battery is exp losive.
- To reduce the danger of explosion, never
connect or disconnect charger cables whi le
the charger is operat ing.
- Fast charging a battery is dangerous and
should only be attempted by a competent
technician with the proper equipment.
- Battery acid that may spill during charging
should be washed off with a solution of
warm water and baking soda to neutralize
the acid .
(D Note
Never use a fast charger as a booster to start
the engine. This will serious ly damage sensi­
tive electronic components, such as control
units, relays, radio, etc ., as well as the battery
charger .
Replacing the battery
Your veh icle is equipped with an inte llige nt ene r­
gy management system for d istr ibut ing elect rici ­
ty ¢
page 138. The battery cha rges better in
vehicles with the en ergy management system
than in vehicles without the system. To ensure
that th e additional pow er is availabl e after re ­
p lac ing the battery, rep lacing w ith the same type
of b attery from the s ame manufac turer ( like the
battery that was delivered with the veh icle) is
recommended . Yo ur authorized deale r must code
the battery in the energy management system to
Ch eck ing and Filling
enable you to use the energy management func­
tions corr ectly aft er replacing the batt ery .
If it is no t possib le to use a battery of this type,
the new battery mus t have the same capacity,
vo ltage ( 12-volts), amperage, construction and
plug sealing.
When install ing the battery, make sure the ig ni­
t ion and all electr ica l cons umers are tu rned off.
Q) Note
- Vehicles, fo r example with a Start-Stop sys­
t em*, a re equipped with a specia l cycle­
proof bat tery (such as an AGM battery). In­
sta lling a different type of battery can cause
prob lems in the veh icle elect rical system .
When replacing the vehicle battery, always
install one w ith the same specifications as
the origina l battery.
- Make sure that the gas venting hose is al­
ways connected to the original opening on the battery s ide . Otherw ise gasses or bat­
tery acid could leak out .
- Battery mounts and clamps must always be
secured correct ly .
- Read and follow the warn ings under
¢
page 313, Working on the battery before
performing any work on the battery.
® For the sake of the environment
Because of the problem of proper d isposa l of
a battery, we recommend your authori zed
Audi dealer change the battery for you. Bat ­
teries contain sulfur ic acid and lead and must
always be disposed of properly in compliance
wi th a ll envi ronmenta l reg ulat ions. Dispos ing
of veh icle bat teries improperly is very da nger­
ous to the environment.

anti-free zing agent should be added to the water
so that it does not freeze .
Cl) Note
-The concentration of anti-free zing agent
must be adjusted to the vehicle operating
conditions in the respective climate. A con ­
centration that is too high can lead to veh i­
cle damage .
- Never add rad iator anti -freeze or other addi ­
tives to the washer fluid .
- Do not use a glass cleaner that contains
paint solvents, beca use this could damage

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden

Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
I t is becoming increasing ly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car wh ich you can only reach
through the eng ine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs for
you, s ince your dealer has the proper tools, the
;;§ correct bu lbs and the expert ise .

~ Gas discharge lamps (Xenon lights): .... 0 0
3 Fuses and bulbs
Due to the high e lectrica l voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker.
LED headlights*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced.
& WARNING ~ -
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
h ig h-vo ltage portions of such lamps!
- Only your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the bulb holders that can cause serious cuts. If
you are uncerta in about what to do, have
the work performed by an authorized Audi deale r or qualified workshop. Ser ious per­
sonal injury may result from improperly per­
formed work.
(D Tips
-If you st ill prefer to replace the light bulbs
yourself, be awa re that the engine compa rt­
ment is a hazardous area to work in~.&..

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
CD Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engin e 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 discharged battery can freeze at tempera­
tures just below 32 °F (0 °C). Before con­
necting a jumper cable, you must thaw the
356
frozen battery completely, otherwise it could explode.
- 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
~page 304.
CD 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.
@ Tips
The discharged battery must be properly con-
nected to the vehicle's electrical system. .,..
