Head AUDI A8 2014 Manual PDF

Traction
The traction grades, from highest to lowest,
a re AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance¢ .&..
Temp eratu re
The temperature grades are A (the highest),
B, and
C, representing the tire 's resistance to
the generat ion of heat and its ability to dissi­
pate heat when tested under controlled condi­
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failu re ¢ .&. .
The grade C corresponds to a level of perform­
ance which all passenger car tires m ust meet
u nder the Federa l Motor Ve hicle Safety Stand­
ard No.
1 09. Grades Band A represent higher
l eve ls of pe rformance on the laboratory test
wheel than the m inimum required by law.
_& WARNING
Th e traction grade assigned to this tire is
based on stra ight-ahead b raking t raction
tests, and does not include acceleration,
cornering , hydrop laning or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es ­
tablished for a t ire that is properly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
separate ly or in combination, can cause
heat buildup and possibl e tire fa ilu re.

Winter tires
Winter tires can improve vehicle handling on
snow and ice . At temperatures below 45 °F
(7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true w inter o r "snow" tir es, those
with very deeply cut t read. These tires should
o nl y be used in pairs and be installed o n all
f o ur wheels . Make sure you p urchase snow
ti res that are the same size and cons truc tion
type as the other tires on yo ur vehicle .
I f your veh icle is eq uipped w ith all-whee l
drive *, t his w ill improve trac tion durin g w in ter
driv ing, even wi th the s tanda rd tires. Howev ­
er, we strongly recommend that you always
equip all four wheels on your veh icle w ith cor­
rect ly fitted winter tires or all-season t ires,
when winter road condit ions are expected.
This also improves the veh icle 's b rak ing per­
fo rmance and reduces stoppi ng d ista nces .
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur whee ls .
As k your au thori zed A udi d ealer or qualified
workshop for permit ted
winter tire size s. Use
o nl y radial winter ti res .
Win ter tires lose their effec tiveness whe n the
tread is worn down to a depth o f
0.15 7 inch
(4 mm) .

Please a lways remember that winter tires may
have a lowe r sp eed rating than the tires o rig i­
nally i nstalled on your veh icle at t he time it

chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severe ly dam­
age the wheelhouse and other parts of
the veh icle .
@ Tips
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with All Wheel Drive.
Wheel bolts
Wheel bolts mu st always be tigh tened to the
correc t torque .
The design of whee l bolts is matched to the
factory in sta lled r ims. If different rims are fit ­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used . This ensures that wheels are f itted
secure ly and that the brake system f unctions
correctly .
In certain circumstances, you may not use
wheel bolts from a d iffe rent vehicle -even if it
i s the same mode l
¢page 294.
A WARNING
Imprope rly tig hte ned or maintained whee l
bolts can be come loose causin g loss of
contro l, a co llision and serious persona l in­
jury .
- Alw ays keep the w heel bolts and the
th reads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the w heel h ubs. They can
become loose while driving if greased or
o iled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the rim being installed.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the co rrect tightening
torq ue for the wheel bo lts to reduce the
Tire s an d wheel s 265
risk of a wheel loss. If the tighte ning tor­
que of t he wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing . If the tighte ning torque is
too h igh, the wheel bol ts and threads
can be damaged and the whee l can be­
come loose.
(I) Note
The specified torque for the whee l bolts is
90 ft lb ( 120 Nm) with a tole ranc e of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. Afte r cha nging a whee l, the torq ue
must be checked as soon as possible wi th a
torque w rench -prefe rably by an au thor­
i z ed Audi dealer or qualif ied workshop .
Low aspect ratio tires
Your Audi is facto ry-eq uipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance , road fee l
and handling under a variety of driving cond i­
tions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation . The numera l rep resents the ratio
of the t ire's sidewall height in relation to its
t read width ex pressed in perce ntage. Conven ­
tion al tires have a he igh t/w idth ratio of 60 or
more.
The performance of low-aspe ct-ratio tire s is
particularly sensitiv e to improper infla tion
pres sure. It is therefore important that l ow
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure is
regularly checked and maintained. Tire pres·
sures should be checked at least once a
month and always before a long trip

What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes , curbs, gul lies ..,.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb . Thi s applies especially to the light bu lbs
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 ser ious cuts, and parts
must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
Headlights with Xenon light can be ident ified
by the high voltage sticke r.
LE D headlights* require no ma intenance .
Please contact your authorized Aud i dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
p lode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bu lbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work ­
shop. Serious personal injury may result
from improperly performed work.
(D Tips
-If you must replace the light bulbs your­
self, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. Always read and
heed all WARNINGS
c> page 231.
-It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.

284 Emergency situations
@ Tips
-The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative
post because the battery manager sys­
tem must be able to detect the battery's
state of charge . Always connect the neg­
ative ground cable to the negative
ground post of the battery manager con­
trol unit.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described below!

•Turnoff lights and accessories, move lever
of automatic transmission to N (Neutral) or
P (Park) and set parking brake.
Connect POSITIVE(+) to POSITIVE(+)
(red)
• Open the red cover on the pos itive terminal
¢ fig. 233 .
1. Connect one end of the red positive cable
on the
jump start bolt c::;, fig. 234 @ (bolt
under the red cover = "positive ") of the ve ­
hicle to be started @.
2. Connect the other end to the positive ter-
mina l@ of the booster battery@.
Connect NEGATIVE (-) to NEGATIVE (-)
(black)
3. Connect one end of the black negative ca­
ble to the negat ive terminal @ of the
booster battery @.
4. Connect the other end to the
jump start
pin © (bolts with hex head bolt= "nega­
tive") of the vehicle to be started @.
Starting the engine
• Start the engine of the veh icle w ith the
booster battery@. Run the engine at a
moderate speed.
• Start engine with discharged vehicle battery
@ in the usual manner.
• If the engine fails to start, do not keep the
starter cranking for longer than 10 seconds.
Wait for about 30 second s and then try
aga in.
• With engine running, remove jumper cables
from both vehicles in the exact
reverse o r­
de r.
• Close the red cover on the positive term inal.
T he battery is vented to the outside to prevent
gases from entering the veh icle inter ior. Make
sure that the jumper clamps are well connect­
ed with their metal parts in full contact with
the battery terminals.
_& WARNING
To avoid serious personal injury and dam­
age to the vehicle, heed all warnings and
instructions of the jumper cable manufac­
turer. If in doubt, call for road service.
- Jumper cables must be long enough so
that the veh icles do not touch.
