& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed . Always know the maximum speed
before driving off . Never drive faster than the speed permitted for
your specific winter tires . This will cause damage to the tires
leading to an accident and serious personal injury to you and your
passengers .
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , loss of control , crashes and serious
& WARNING (continued )
personal injuries . Have worn or damaged tires replaced immed i­
ately.
• Winter tires have maximum speed rating that may be lower
than your vehicle' s maximum speed.
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated .
& WARNING
Always adjust your driving to the road and traffi c conditions .
Never let the good acceleration of the winter tires and all -wheel
drive tempt you into taking extra risks. Always remember :
• When braking, an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions .
ci' For the sake of the environment
Use summer tires when weather conditions permit. They are
q ui ete r, d o not wear as quickl y a nd re duc e fu el cons ump tion. •
Snow chains
Sno w chains may be fitted o nly to t he fro nt whe els, a nd o nly to
certain tire sizes . Ask your authorized Audi dealer on which tire
s iz es sn ow c hain s ca n be use d.
I f you are going to use snow chains, then you must install them on
the front wheels at least .
The s now chains must have l ow- pro file links a nd must n ot be thick er
than 0.53 inc h (13.5 mm), including the lock . .,_

& WARNING
Using the wrong snow chains for your vehicle or installing them
incorrectly can increase the risk of loss of control leading to
serious personal injury.
• Snow chains are available in different sizes . Always make sure
to follow the instructions provided by the snow chain manufac ­
turer .
• When driving with snow chains never drive faster than the
speed permitted for your spec ific snow chains.
• Always observe local regulations.
0 Note
• Remove s now c hains befo re driv ing on roads no t cove re d w it h
snow to avoid damag ing tires and wearing the snow chains down
un nece ss aril y.
• Snow chains, whic h come into direct contact with the wheel rim,
can scratch or da mag e it. There fo re , m ake sure t hat th e s now ch ai ns

Wheel bolts
W heel bo lts mu st a lways be ti ghte ned to t he corr ect
t o rq ue .
The design of wheel bolts is matched to the facto ry instal led rims . If
diff eren t rim s are fitt ed, t he cor rect w heel bol ts with the r ig ht le ngth
and correctly shaped bolt heads must be used. This ensures that
w hee ls a re fitted securely and t hat t he brake sys te m funct io ns
correctly.
In cer tain ci rc u ms tances, yo u may no t use whee l b olt s fro m a
different vehicle -even if it is the same model~
page 295.
& 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 be ing 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 threads can be damaged and the wheel can become
loose .
0 Note
The specified torq ue for the wheel bolts is 9 0 ft lb (120 Nm) with a
t o lerance of± 7,4 f t lb (± 10 N m). To rque w hee l bo lt s d ia g ona lly .
After chang ing a wheel, the torque must be checked as soon as

than the size indicated on the vehicle placard or tire inflation pres­
sure label, you should determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system* (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significantly
under-inflated. Accord ingly, when the low tire pressure te lltale illu­
minates, you should 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 -inflation also reduces fuel efficiency and tire 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 lumination 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 properly . 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 wil l 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 detec t or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the
installat ion of replacement or a lternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the rep lacement or
a lternate tires and wheels al low the TPMS to continue to function
proper ly .•

Introduction
The tire pressure monitoring system* monitors air pres ­
sure in all four road wheels while the vehicle is moving.
As soon as the tire pressure monitoring system* senses a signifi­
cant loss of air pressure in one or several tires, text messages and
yel low symbols appear in the instrument cluster disp lay to alert the
driver. The ) warning light in the instrument cluster comes on
when the tire is significantly underinflated
:::> page 17 .
The warning light Cl' also i lluminates in the case of a system
malfunction.
Be aware that tire pressure is a lso dependent on the temperature of
the tire. For every 18
°F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1.5 psi (0 .1 bar). The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure only when they are
cold, when the temperatu re of the t ires
is roughly the same as the ambient air temperature .
I n order to keep the tire pressure monitoring system * properly ca li­
brated, tire pressure on all four tires shou ld be checked at regu lar
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure)
:::> page 256 .
The tire pressure is shown on the label located on the driver's side
B -pillar (visible when the door is open) .
& WARNING
• When the tire pr essure monito ring system * wa rning light i s lit ,

• Always observe local regulations. •
Dimensions
The specifications refer to the basic model. Differences may occur
depend ing on the mode l type and op tions ordered, for examp le, tire
sizes.
0 Note
When driving up steep ramps, on rough roads, over curbs, etc. it is
important to remembe r tha t some parts of your vehicle, such as
spoilers or exhaust system components, may be close to the
ground. Be careful not to damage them. •
