New tires or wheels
Aud i recommends having all work on tires or
wheels performed by an authorized Audi dealer
or author ized Audi Se rvice Facility . These fac ili­
ties have the proper know ledge and are equipped
with the required too ls and replacement parts.
• New tires do not yet have the optimum grip­
ping properties. Drive caref ully and at moder ­
ate speeds for the first 350 mi les (500 km)
with new tires.
• Only use tires w it h the same design, size (roll­
i ng c ircumference) and as close to the same
tread patter n as poss ible on all four wheels .
• Do not replace t ires individua lly. At least re­
pla ce both t ires on the same axle at the same
t ime .
• Audi recommends that you use Aud i Original
Tires . If you wou ld like to use different tires,
please note that the tires may perform differ­
ently even if they are the same
si ze ¢ ,& .
• If you would like to equip your veh icle w ith a
tire/rim comb inat ion that is different from
what was installed at the factory, consult w ith
an aut horized Aud i dea ler o r authorized Audi
Se rvice Facility befo re making a
purchase ¢,& .
The spare tire* is different from the regular tires
insta lled on the veh icle
-for example, if w inter
tires or w ide tires a re ins talled
-so only use the
spa re ti re* tempo rar ily in case of emergen cy and
d rive caref ully wh ile i t is in use . It should be re ­
p laced w it h a regular t ire as soon as possib le.
Applies to: vehicles with all wheel drive: all four
wheels must be eq uipped w ith tires that are the
same brand and have the same construc tion and
tread pattern so that the drive system is not
damaged by different wheel speeds. For this rea­
son , in case of eme rgency, only use a spare tire*
Wheels
that is the same circ umfe rence as the regular
tires.
A WARNING
--On ly use t ire/rim comb inations and suitab le
wheel bo lts that have been approved by
Aud i. Otherwise, damage to the vehicle and
a n accident could res ult.
-For technical reasons, it is not possible to
use t ires from other ve hicles
-in some cas­
es, yo u cannot even use tires from the same
veh icle model.
-Make sure that the tires you select have
e nough clearance to the veh icle. Rep lace­
ment tires should not be chosen s imply
based on the nomina l size, because ti res
wit h a differe nt constru ction can diffe r
g reatly even if they are the same size . If
there is no t enough clearance, the tires or
the vehicle can be damage d and this can re­
duce dr iving safety and increase the risk of
an accident.
-On ly use t ires that are more than s ix years
old when absolutely necessa ry and drive
carefully when doing so.
- Do not use run -flat tires on your vehicle . Us­
ing them when not perm itted can lead to
veh icle damage or accidents.
- If you install wheel covers on the vehicle, make sure they allow enough air circulation
to cool the brake system. If they do not, t his
could increase the risk of an acc ident.

Wheels
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­ ty") with an assumed weight of 150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer , the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
340
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
c::> page 336,
fig. 280.
A WARNING
=
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carry ing more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to- tal load being transported

Care and cleaning
A WARNING
- Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
-After washing the vehicle, the braking effect may be delayed due to mo isture on the
brake rotors or ice in the winter. This in­
creases the risk of an acc ident. The brakes
must be d ried first w ith a few careful b rake
applications.
(D Note
- If yo u wash the ve hicle in an automatic car
wash, yo u m ust fold the exte rior m irrors i n
to reduce the risk of damage to the mir rors.
Power folding exte rior mir rors* mus t onl y
b e fo lded i n and ou t using the powe r folding
funct ion .
- T o reduce t he risk of paint damage, do no t
wash the vehi cle i n dire ct sunlig ht.
-
- To red uce the risk of damage, do not wash
the power top* with a pressure washer.
- T o reduce the risk of damage to the s urface,
do not use insect removing sponges, kitchen
sponges o r similar items .
- Mat te finish painted vehicle components:
- To reduce the r isk of damage to the sur-
face, do not use polis hing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash the veh icle in facili ties spec ially de­
s igned for that pu rpose. This will reduce the

for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; you risk injuring
yourself.
- Never start the engine when the vehicle is
raised, which could cause an accident.
- Support the vehicle securely with appropri­
ate stands if work is to be performed under­
neath the vehicle; otherwise, there is a po­
tent ial risk for injury.
