2014 AUDI S4 warning

260 What do I do now?
-Check the tire pressure on the spare imme­
diately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as possible by your authorized Audi dealer or
qualified workshop.
- With steel and alloy wheel rims , the wheel
bolts are correctly tightened at a torque of
90 ft lbs . (120 Nm).
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing
a tire, they should be replaced before you
check the tightening torque .
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover.
Until then, drive with extra care and at re ­
duced speeds .

The fuses are located at the front left and
r igh t of the cockpit and behi nd the trim on
the right side of the luggage compartment .
.. Turn
off the ignit ion a nd the affected electri­
ca l consume rs .
.. Check the following table to see which fuse
belongs to the consumer .
.. Remove the appropriate cover
Q fig. 207 or
Q page 213, fig. 178 .
.. To remove the purple plastic clip if necessa­

pla ce the blown fuse w ith an identical new
one.
& WARNING , -
Do not repair f uses and never replace a
blown fuse w ith one that has a higher amp
rating. This can cause damage to the elec­
trical system and a fire.
11 You can dispose of the plastic clip after removing it.

If a new fuse burns out again after short ly
have you have insta lled it, have the electri ­
ca l system checked by your authorized
Audi dealer .

Bulbs
Replacing bulbs
For your safety, we recommend that you hove
your authorized Audi dealer replace any bulbs
for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb. This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb holders 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 p roper­
l y resea led.
For your safety, we recommend that you have
you r authorized Aud i dea ler replace any bulbs
for you, since yo ur dealer has the proper tools,
the correct bulbs and the expertise .
Gas discharge lamps (Xenon lights)*:
Due to the high electr ical voltage, have the
bulbs replaced by a qualif ied technician .
Headlights wit h Xenon light are identified by
the high voltage sticker .
_&. WARNING
Changing Xenon lamps witho ut the neces­
sa ry equipment can cause serious personal
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working per sonnel who
have the necessary tools and equ ipment to
perform these ope rations.
Starting by pushing or
towing
Q;) Note
Vehicle s with an automati c transmission
cannot be started by pushing or towing .
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discha rged or wea k batte ry, the battery can be
connected to the battery o f
another vehicle,
using a
pair of jumper cables to start the en­
g ine .
Jumper cables
Use only jumper cab les of sufficiently
large cross section to carry the starter cur rent
safely. Refer to the manufact urer's spec ifica­
ti ons.
Use on ly jumper cables with
insulated te rmi­
na l clamps wh ic h are d istinctly mar ked :
plus (+) cable in most c ases co lore d red
minu s (-) cable
in most cases colored black .
A WARNING

safe ha ndling of your ve hicle's bat tery.
- Alw ay s sh ield yo ur eye s and a vo id le an­
ing over the batte ry w henever p ossib le . -
A discharged battery can freeze at tem­
pe rat ures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the fr ozen battery complete ly , ot h­
e rwise it cou ld explode.
- Do not allow batte ry acid to contact eyes
or skin . Fl ush any contacted a rea wi th
wate r im media tely.
- Imp roper use of a booster battery to
s tart a vehicle may cause an explosion.
- Vehicle batter ies generate explosive gas­
es . Keep sparks, flame and lighted ciga­
rettes away from ba tte ries .
- Do not try to jump start a ny ve hicle w ith
a low ac id leve l in the battery .
- The vo ltage of the booster batte ry m ust
a lso have a 12-Vo lt rat ing . The capacity
(A h) of the booster batte ry should not b e
lowe r than that of the discharged bat­
tery . U se o f batt erie s of d iffe ren t voltage
or subs tanti ally diffe ren t "Ah" rat ing

T he capac ity (Ah) of the booster battery
should not be lower than that of the dis­
charged batte ry.
- Before you check anything in the engine
compartment, always read and heed a ll
W ARNI NGS¢
page 214.
(D Note
- App lyi ng a hig her voltage booste r bat­
tery wi ll cause expens ive damage to sen­
sitive e lectronic components, such as
cont ro l units, relays, rad io, etc.
- There must be no electrical contact be­ twee n the vehicles as otherwise current
co uld already start to f low as soon as t he
posi tive(+) terminals a re con nected . ..,.

@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charg ing the
battery, never connect the negative
ground cable to the battery negat ive post
because the ba ttery manager system must
be ab le to detect the battery's state of
charge. Always connect the negative
g round cab le to the negative ground pos t
of t he battery manager cont ro l unit.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described b elow!

The procedure described below for connecting
jumper cables is intended to provide a jump
start for your veh icle .
Vehicle with di scharged battery :
~Turnoff lights and accessories , move lever
of automatic transmission to N (Neutral) or P (Park) and set parking brake .
Emergency situ ation s 267
Connect POSITIVE(+) to POSITIVE(+ )

1. Connect one end of the red positive cable
on the
jump sta rt bolt c::;, fig. 212 (D
(Bolts under cove r= "posit ive ") of the ve­
hicle to be started @.
2 . Conne ct the othe r end to the pos itive ter -

~ W ith engi ne runni ng, remove jumpe r cab les
from both vehicles in the exa ct
reverse o r­
der .
~ Close the cover on the positive pole .
T he b attery is vented to the o utside to p reven t
gases from en tering the veh icle in ter ior . Ma ke
s ur e that the j umper clamps a re well connect­
ed with their
metal ports in full contact with
the batte ry term inals.
A WARNING
To avoid serious personal injury and dam­
age to the vehicle, heed all warnings and
in structions of the jumper cable ma nufac-
turer . If i n dou bt, call for road servic e.

268 Emergency sit uat ions
-Jumper cables mus t be long enough so
that the vehicles do not touch.
- W hen connecting jumper ca bles, ma ke
sure t hat they cannot get caught in any
moving parts in the eng ine compart­
ment.
- Do not bend over the batteries - danger of chemical burns!
- The battery ce ll locking screws must be
tightened securely .
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
9 page 214.
Improper hook-up of jumper cables can r u­
in the generator.
- Always connect POSITIVE( +) to POS I­
TIVE(+), and NEGATIVE( -) to NEGATIVE
( - ) ground post of the battery manager
control unit.
- Check that a ll screw plugs on the battery
cells are screwed in firmly. If not, tighten
plugs p rior to connecting clamp on nega­
tive battery terminal.
- Please note that the procedure for con­ nect ing a jumper cable as described
above applies spec ifically to the case of
you r vehicle being jump started. When
you are giving a jump start to another ve­ hicle, do
not connect the negat ive( -) ca­
ble to the negat ive (-) term inal on the
discharged battery@)
9fig. 212. In­
stead, securely connect the negative(- )
cable to e ither a solid metal component
that is firm ly bolted to the engine block
or to the engine block itse lf. If the bat­
tery 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 tow­
ing.
T he following information is to be used by
commercial tow truck operators who know
how to operate their equipment safely.
