chains because t he 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 ve
hicles with All Wheel Drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory installed 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 fitted
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 285.
A WARNING
Imprope rly tig hte ned or maintained whee l
bolts can be come loose causing 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 wh ile 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 maintai n the co rrect tightening
torq ue for the wheel bo lts to reduce the
Tire s an d wheel s 255
risk of a wheel loss. If the tightening 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) wi th a tole rance 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
ized 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 u nder 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 numeral rep resents the ratio
of the t ire's sidewall height in relation to its
t read width ex pressed in pe rce ntage. Conven
tiona l 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 low
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure i s
regularly checked and maintained. Tire pre s·
sures should be checked at least once a
month and always befo re a long trip
¢ page 244, Checking tire pressure.
What you can d o to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes , curbs, gul lies ..,.

other warning devices to alert other mo
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac
ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- After installing the spare wheel, make
sure that you replace the flat tire/wheel
in its storage area properly and tighten
the knurled retaining screw securely.
@ Tips
Before changing the wheel, you must acti·
vate the jacking mode, so that the auto
matic controls for the Adaptive Air Sus
pension do not make it more difficult to
lift the vehicle with the jack ¢
page 265.
Changing a wheel
When you change a wheel, follow these
quence described below step-by-step and in
exactly that order.
1. Activate the vehicle jack mode
¢ page 265.
2. Remove the decorative wheel cover*. For
more details see also¢
page 264, Deco
rative wheel covers
or ¢ page 264,
Wheels with wheel bolt caps.
3 . Loosen the wheel bolts¢ page 264 .
4. Locate the proper mounting point for the
jack and align the jack below that point
¢page 265.
5. Raise the car with the jack¢ page 265.
6. Remove the wheel with the flat tire and
then install
the spare ¢ page 266.
What do I do now? 263
7. Tighten all wheel bolts lightly.
8.
Lower the vehicle with the jack.
9. Use the wheel bolt wrench and
firmly
tighten all wheel bolts¢ page 264.
10. Replace the decorative wheel cover*.
11. Deactivate the vehicle jack mode in the
MMI:
ICARI function button > Car systems
control button > Servicing & checks> Air
susp.: jack mode> Off .
The vehicle jack mode switches off automati
cally at speeds above 10 km/h .
A WARNING
Always read and follow all WARNINGS and
information¢ .&
in Raising the vehicle on
page 265
and ¢ page 267.
After changing a wheel
A wheel change is not complete without the
doing the following.
.. Store and secure the wheel you replaced in
the spare wheel well.
.. Replace the tools and the jack in their prop
er location.
.. Check the
tire pressure on the spare wheel
immediately after mounting it.
.. As soon as possible, have the
tightening
torques
on all wheel bolts checked with a
torque wrench. The correct tightening tor
que is 90
ft lb (120 Nm).
.. Have the flat tire
replaced as soon as possi
ble .
(D Tips
-If you notice that the wheel bolts a re
corroded and difficult to turn while
changing a tire, they should be replaced
before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.

266 What do I do now ?
-Make sure that passengers wait in a
safe p lace away from the vehicle and
well away from the road and traffic.
- Make sure jack position is correct, ad
just as necessary and then continue to ra ise the jack.
- Changes in temperature or load can af
fect the height of the vehicle.

2 7 4 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 g round 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!
Fig . 209 Engine compartme nt: connecto rs for jump
start cab les and a charger
Fig. 210 Jump starting w ith the battery of another ve
h icle: A - boos ter battery, B - discharged veh icle battery
The procedure described below for connecting
jumper cables is intended to provide a jump
start for your veh icle.
Vehicle with discharged battery :
.. Turn off 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 positive terminal
¢fig. 209 .
1. Connect one end of the red positive cable
on the
jump start bolt ¢ fig. 210@ (bolt
under the red cover = "positive") of the ve
hicle to be started @.
2 . Connect the other end to the positive ter-
mi nal @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 @. Ru n 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 crank ing for longer than 10 seconds.
Wait for about 30 seconds and then try aga in .
.,. With engine running, remove jumper cables
from both vehicles in the exact
reverse or
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 vehicle inter ior. Make
s ur e that the jumper clamps are well connect
ed with their meta l parts in full contact with
the battery terminals.
_& WARNING
To avoid se rious personal injury and dam
age to the vehicle, heed all warnings and
in structions 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.
