242 Checking and filling
@ For the sake of the environment
Be cause of the problem of proper disposa l
of brake flu id as we ll as the special tools
req uired and the necessary expert ise, we
recommend that you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
Unde r normal operating conditions, the bat
tery in your A udi does not need any mainte
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the elect ro lyte level checked by an authorized
Aud i dea ler o r qualified workshop . The elec
trolyte leve l sho uld a lso be c hecked each t ime
the battery is c harged ¢
page 244.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a bat tery that is older tha n 5 yea rs .
W ith certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec
tr ica l system fo r safety reasons ¢

pair, core and disposal of the airbags on
page 171.
Hybr id d rive *: you can find important i nforma
tion about the high voltage battery under
¢ page 97.
Disconnecting the battery terminals
Some veh icle functions (power w indow regu
lators, for example) are lost if the battery ter
minals a re discon nected. These functions have
to be re learned after the ba tte ry term inals a re
connect ed aga in. To prevent this , the battery
should only be d isconnected from the vehicle
e lec tric al sys te m whe n absolu tely necessa ry
for rep airs.
Vehicles not driven for long periods
If yo u do not dr ive you r vehicle over a pe riod
of severa l days or w eeks, ele ct rical com po
n e nt s are gr adually cu t ba ck o r swi tched off .

adjustment, may not be availab le. T he con
venience functions will be avai lab le aga in
when you tu rn on the ign ition and start t he
engine.
Winter operation
Du ring the winte r mon ths, bat tery ca pac ity
tends to dec rease as tem peratures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear wi ndow de
fogger, etc ., are used more often.
Avoid unnecessary powe r consum ption, pa r
t icu lar ly in city traffic or when traveling only
sho rt distances. Let your authori zed Aud i
dealer check the capacity of the vehicle bat
te ry before winter sets in ¢
page 244. A well
c h arged battery will not on ly preven t starti ng
problems when the wea ther is cold, but w ill
also last lo nger.
Working on the battery
Be especially careful when working on or near
the ba ttery.
The battery is located in the luggage compart
me nt under the floor . B efo re you c hec k any

272 What do I do now ?
Performing the repair
App lies to vehicles: with tire repair kit
Fig. 217 Perform ing the rep air
Pre parati ons
.. Park the vehicle as far as possible from mov
ing traffic in the event of a flat tire.
.. Set the
parki ng brake to prevent the vehicle
from roll ing unintentionally .
.. Shift the
se lec tor le ver in to th e P po siti on.
.. Determine whethe r a repair w ith the tire re
pair kit is possible or not
¢ page 271.
.. Let all of the passengers ex it th e vehicle
and move a safe distance away ¢& .
.. Take the
sealant bottle and the compre ssor
out of the luggage compartment
¢ page 104, fig. 112.
.. Affix the label "max. 50 mph (80 km/h)",
found on the sealant bottle, to the instru
ment cluster where it can be seen by the
dr iver .
Fill ing a tire
.. Shake the bottle thoroughly before f il li ng.
.. Screw the accompanying filling hose com-
pletely onto the bottle. This breaks through
the foi l seal automatically at the connec
t ion.
.. Remove the valve cap from the tire va lve and
uns crew the valve inse rt using the accompa
nying valve insert too l¢
fig . 217.
.. Lay the valve insert on a clean s urface .
.. Remove the sealing p lug from the filling
hose and connect the hose to the tire va lve .
.. Hold the bottle with the bottom fac ing up
ward and empty the entire contents into the
tire.
.. Then pu ll out the hose and screw the valve
i nsert tightly back into the tire valve .
Inflating a tire
.. Screw the fill ing hose for the compressor
onto the tire valve and insert the connector
into the cigarette lighter .
.. Inflate the tire to between 29 PSI (200 kPA)
and 36 PSI (250 kPA) and read the pressure
on the gauge .
.. If this tire pressure is not reached, dr ive
your veh icle approximately 33 ft ( 10 meters)
forward or backward so that the sealant can be red istr ibuted inside the tire.
If at this
time the requi red a ir pressure st ill cannot be
reached , the tire is too badly damaged and
cannot be repaired with the tire sealant .
Final inspection
.. Stop the vehicle after driving for about 10
m inutes and check the tire pressure .
.. If the tire pressure is lower than 19 PSI
( 1 30 kPA), then the tire is too seve rely dam
aged. Do not continue driving . Please seek
professiona l assistance.
A WARNING
--
- Turn on the emergency flashers if you
have a flat tire while in moving traffic .
This is for your protect ion and the for the
safety of other drivers.
- Take care to move all of the passengers
to a safe place (behind a guard ra il for
example) .
- Read and follow the manufacturer's safe
ty precautions on the compressor and in
the instructions on the bottle of sealant!
- If a tire pressure of 29 PSI (200 kPA) cannot reached after inflating for 12 m i
nutes, then the t ire is too severe ly dam
aged. Do not cont inue driving.
- Obta in qualified help if it is not possible
to pe rform the repair w ith the tire seal
a nt .
- I f the tire pressure is less than 19 PSI
(130 kPA) afte r 10 minutes of d riving,
then the t ire is too severely damaged . Do
not continue dr iving. Seek p rofess ional
assistance .
(D Note
Special care is required if you are repairing
the tire on a steep incline.
@ Tips
-Do not operate the compressor for more
than 12 minutes continuously, otherwise it can overheat. Once the compressor has
cooled, you can continue to use it.
- If sealant has spilled out, let it dry and
then you can remove it by peeling it away
like a foil.
- Remember to obtain a new bottle of
sealant from your authorized Audi dealer
after repairing a tire. After this, the func
tionality of the tire repair set is restored.
- Obey all laws.
Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang
ing a wheel.
.,. After you experience a tire failure, pull the
car well away from moving traffic and try to
reach
level ground before you stop¢_& .
.. All passengers should
leave the car and
move to a safe location (for instance, behind
the guardrail) ¢
_&.
.. Engage the parking brake to prevent your
vehicle from rolling unintentionally¢_&.
.. Move
selector lever to position P ¢ _& .
.,. If you are tow ing a trai ler: unhitch the trail
er from your vehicle.
.,. Block the diagonally opposite wheel with
the folding chocks or other objects.
.. Take the
jack* and the inflatable spare tire*
out of the luggage compartment
¢page 268.
A WARNING
You or your passengers could be injured
while changing a wheel if you do not fol
low these safety precautions:
-
What do I do now? 273
- If you have a flat tire, move a safe dis
tance off the road. Turn off the engine,
turn the emergency flashers on and use
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 with the fold
ing chocks or other objects. 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*.
- Always store the vehicle tool kit, the
jack* and the replaced tire in the luggage
compartment
¢page 145.

the mat ing s urfaces of both the wheel
and the hub. Remove a ll dirt from these
su rfaces before remo unting the wheel.
What do I do now? 277
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a spa re tire with a tread pattern
intended for use in a specific direction
When using a spare t ire wi th a tread pat ter n
intended for use in a spec ific d irect ion, please
note the fo llowing :
- The d irect io n of rotation is marked by an ar
row on t he side of the ti re .
- If the spare tire has to be insta lled in the in
correct d irect ion, use the spare tire only
temporarily s ince the t ire will not be able to
achieve its optimum performance cha racte r
is tic s w it h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu lar at
t en tion to th is f act d uring we t wea ther and
t ha t you adjus t you r speed to m atch r oad
conditions .
- Repla ce the fl at t ire wi th a new o ne and
have i t installed on your vehicle as soo n as
possible to resto re the han dling advantages
of a u nidirectional tire .
Notes on wheel changing
Please read the information¢ page 258, New

diately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon a s
possible by your authorized Audi dealer or
a qualified workshop.
- With steel and alloy wheel rims , the wheel
bolts are cor re ctly tightened at a torque of
105 ft lb (140 Nm).
- If you notice that the wheel bolts are cor
roded and diff icult to turn while changing
a tire, they should be replaced before you
check the t ightening torque. .,,.
