Wheel bolts
W heel b olts mus t al wa ys be tigh te n ed to t he cor rect
to rqu e.
The design of wheel bolts is matched to the factory instal led rims . If
d ifferen t rims are fitted, the co rrect w heel bo lts wit h th e rig ht length
and correctly shaped bolt heads m ust be used. This ensures that
w hee ls are fitt ed s ecure ly a nd th at t he brake sys te m funct ions
correctly .
I n certain circums tances, yo u may no t use w heel b olts fr om a
differ ent vehicle -even if it is the same mode l.
&_ WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and th reads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
t ole ranc e of ± 7,4 ft lb(± 1 0 Nm). To rque whee l bolts diag onally.
After changing a wheel, the torque must be checked as soon as possible with a to
rque wrench -preferab ly by an authorized Audi

Low aspect ratio tires
Yo ur Audi is fac tory-equip ped wi th l ow asp ect rati o tires. Th ese tires
have been thorough ly tested and been selected specifically for your
mod el for thei r su per b p erfo rma nce, road feel an d handl in g u nder
a variety of driving conditions . Ask your author ized Aud i dea ler for
mo re deta ils.
T he low aspec t ra tio o f th ese t ires is ind icate d by a numera l o f 55 or
less in the t ire's size designation. The numera l represents the ratio
of the ti re's s idewa ll height in re la ti on to its tread w idth e xpress ed
in percentage. Conventiona l tires have a height/width ratio of 60 or
mo re .
The performance of low -aspect -ratio t ires is part icularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and alway s before a
long trip=>
page 250, "Checking tire p ressure".
What you can do to avoid tire and rim damage L ow a spect rati o tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particu larly if the t ire
is underinflated.
In orde r to minimi ze the occurrence o f im pact da mage to th e tire s
of your vehicle, we recommend that you observe the fo llowing
p reca utions:
• Always ma intain reco mm ende d inflat io n pressu res . C heck your
tire p ressure every 2, 000 miles (3 ,000 km) and add ai r if neces sary .
• D rive car eful ly on roads with potholes, deep gullies or ridges.
Th e impact from d riving th ro ugh o r ove r such o bstac les can
dama ge you r tires . Impact w ith a curb may also cause da mage to
your tires . .,_

Tire pressure monitoring system*
Applies to vehicles: with tire pressu re monitoring system
General notes ' J
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom ­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has t ires of a d ifferent size
than the size indicated on the vehicle placard or tire inflation pres­
sure label, you should determine the proper tire inflation pressure
for those ti res.)
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that i lluminates a low tire
pressure tellta le when one or more of your tires is significantly
under-inflated. Accord ingly, when the low tire pressure telltale illu­
minates, you shou ld stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat and can lead to tire
failure . Under -inflat ion also reduces fuel efficiency and t ire tread
life, and may affect the vehic le's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte ­
nance, and it is the driver's responsibi lity to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
il luminat ion of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS ma lfunction indi­
cator to indicate when the system is not operating proper ly . The
TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the tellta le wi ll
flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the insta
llation of replacement or alternate tires or wheels on the
vehic le that prevent the TPMS from functioning properly. Always
check the TPMS malfunction tellta le after replac ing one or more
tires or whee ls on your vehicle to ensure that the replacement or
a lternate tires and wheels a llow the TPMS t o continue to funct ion
properly. •
Applies to vehicles: with tire pressur e monitoring system
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the tire p ressure monitoring system senses a significant
loss of air pressure in one or severa l tires, text messages and ye llow
sy mbo ls appear in the instrument cluster display to alert the driver.
The warning light in the instrument cluster comes on when the
tire is significantly underinflated
=> page 13 .
Th e warning light l also i lluminates in the case of a system
malfunction.
Be aware tha t tire pressure is a lso dependent on the temperature of
the tire . For every 18 °F (1 O °C) increase in tire temperature, tire pres ­
sure increases by about 1.5 psi (0 .1 ba r). The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure on ly when they are
cold, when the temperature of the tires
is roughly the same as the ambient air temperature.
I n order to keep the tire pressure monitoring system properly ca li­
b rated, tire pressure on all four tires shou ld be checked a t regu lar
interva ls, adjusted if necessary, and saved in the proper setting
(reco mmended pressure) :::>
page 266.
The tire pressure is shown either on the driver's side 8 -pi llar or on
the inside of the fuel fi ller flap. _..

& WARNING
Always store jacking equipment, spare wheel in the luggage
compartment. Tighten screw for the spare wheel securely. Under
no circumstances should you store the spare wheel or jack and
tools unsecured in the passenger compartment. This could cause
serious personal injury to passengers in the vehicle in case of a
collision.
• The compact spare tire is for temporary use only and is so
marked on the sidewalls.
• Do not drive at speeds exceeding 50 mph (80 km/hi with the
compact spare wheel mounted. Also rapid acceleration, hard
braking and hard cornering must be avoided to help prevent loss
of vehicle control.
• Any continuous road use of the compact spare tire may result
in tire failure, loss of vehicle control and injury to vehicle occu­
pants.
• Do not put a snow chain on your compact spare tire. Due to the
smaller tire size, the chain will not fit properly and can thus
damage your vehicle. You could also lose the chain, as well as
control of the vehicle .
• If you have a flat front tire in road conditions which require
snow chains, first remove the undamaged rear wheel and mount
the compact spare wheel in its place. Then remove the damaged
front wheel, take the snow chains off it and attach them to the
wheel taken from the rear. This wheel can now be mounted on the
front with its snow chains. Check and adjust tire pressure promptly.
• Never use two or more compact spare tires at the same time.
0 Note
When using the compact spare wheel, note the following: •
After installing the compact spare wheel, the tire inflation pres­
sure should be checked and, if necessary, increased to 60 psi (4 .2
barl.
• The load carrying capacity is marked on the tire sidewal ls and
must not be exceeded .
• After installing the compact spare wheel, make sure that you
remount the flat tire in its storage area properly .
• The compact spare tire should be properly remounted in its
storage area as soon as the standard road tire can be replaced.
• Because the compact spare tire was specifically designed for
your vehicle, it must not be used on any other vehicle . Likewise,
compact spare wheels from other vehic les must not be used on your
vehicle.
• The compact spare tire must not be mounted on any other
wheels, nor must standard tires, snow tires, wheel covers or trim
rings be used with the compact spare wheel. If such use is
attempted, damage to these items or other vehicle components
may occur.
[ i] Tips
Check the inflation pressure of the compact spare tire (60 psi/4 .2
bar) periodically to keep the tire ready for use .•
Wheel change
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing 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
