Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
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-
214
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
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.

0 0)
A WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death .
- Carrying 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 su re that the to­
tal load being transported - inc lud ing the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle We ight Rating.
Determining correct load

~ Use the example below to calcu-
"' 8 late the total weight of the pas­s ..
Wheels
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed .
Steps for Determining Correct
Load Limit
1 . L ocate the statement "THE
COMB INED WEIGH T OF OCCU­
P ANTS AND CARGO S HOU LD
N EVER EXCEED XXX KG OR XXX
L BS " on your vehicle's placard
(tire inflation pressure label)
<=> page 211, fig. 187.
2. Determine the combined
weight of the driver and pas ­
sengers that will be riding in
your vehicle .
3 . Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
<=> page 211, fig . 187 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity . For ex ­
ample, if the "XXX" amount
equa ls 1400 lbs. and there will
be five 150 lbs. passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lbs.

Winter tires
Winter t ires signif icant ly imp rove the vehicle's
handling when dr iv ing in winter conditions. Be­
c au se of their construct io n (w id th, compou nd,
t read pa ttern), s ummer tires prov ide less t rac ­
tion on ice and snow .
.,. Use winter tires on all four wheels.
.,. Only use winter tires that a re app roved fo r yo ur
veh icle .
.,. Please note that t he maximum permitted
speed may be lower with winter
tir es ¢ A in
G en eral information on pag e 201 .
An a uthor ­
i z ed Aud i dealer or authori zed Aud i Serv ice Fa­
cility can inform you about the maximum per­ m itted speed for your tires .
.,. Check the tire pressure after installing wheels
ca:;, page 211 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 i n (4 mm) . The characte rist ics of winter
t ir es also decrease g reatly as the t ire ages , re­
gard less of t he rema ining t read.
@ For the sake of the environment
Re insta ll summer t ires at the app ropr iate
time, bec ause they prov ide better handli ng
when ro ads are free of snow and ice. Summer
tires cause less roa d noise, tire wear and fue l
consumpt ion .

a co .... N
" N .... 0 0 \,;J ' (D Tips
You can also use all season tires instead of
winter tires . Please note that in some coun­
tries where winter tires are required, only
winter tires with
the ~ symbol may be per­
mitted.
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking .
.. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.. Check and correct the seating of the snow
chains after dr iv in g a few feet, if necessary . Fol­
low the instructions from the manufacturer .
.. Note the maximum speed of 30 mph (SO km/
h). Note the loca l regulations.
Use of snow chains is only perm itted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author ­
ized Audi Service
Facility to see if you may use
snow chains.
You must remove the snow chains on roads with­
out snow. Otherwise, you could impair driving
ability and damage the tires.
A WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent .
{[J) Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them . Remove the wheel covers*
first . Use coated snow chains.
- Using snow chains that add more than 0.4
inch (10.5 mm) of height can severely dam­
age the wheel housings and other vehicle
components.
- Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be very low. If
Wheels
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch on sport
mode¢ page 120.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style . However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
Low -profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers , and
curbs . Therefore, it is particularly important to
maintain the correct tir e pressure
¢ page 211.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage . For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires .
Uniform tire quality grading
-Tread wear
- Traction AA ABC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width

Tread wear
The tread wear grade is a comparat ive rat ing
based on the wear rate of the t ire when tested
unde r contro ll ed conditions o n a specified gov ­

ill General notes
Each tire, including the spare (if prov ided),
shou ld be checked monthly when cold and inflat­
ed to the i nflat ion press ure recommended by the
vehicle manufacture r on the veh icle placard or
ti re infla tion p ressure labe l. (If your ve hicle has
t ir es of a diffe rent size t han the si ze ind icated on
t h e ve hicle placard or tire i nflat io n press ure la ­
bel, you sho uld dete rm ine the proper tire in fla­
tion press ure for those tires) .
As a n ad ded safety featu re, you r vehicle has been
equipped wi th a t ire p ress ure mon itor ing system
(TPMS) t hat ill umi nates a low tire p ressure tell ­
ta le w hen one or mo re of your tires is s ignificant ­
l y under -inflated. According ly, w hen the low ti re
pressure telltale illum inates, you sho uld stop and
c h eck your t ires as soon as possible, and inflate
them to the proper pressure. Dr iv ing on a sign ifi­
cant ly under -inflated t ire ca uses the t ire to over ­
heat and ca n lead to tire fa ilu re . U nder-inflation
also red uces fue l eff ic iency a nd tire tread life,
and may affect t he ve hicl e's handling a nd s top-

0 0 \,;J ' Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inf lation has not reached the level
to trigger illum ination of the TPMS low tire pres­
sure telltale .
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined w ith the low tire
pressure telltale. Whe n the system detects a
malfunct ion, the telltale will flash for approxi­
mately one minu te and then remain cont inuous ly
i llum inated. This sequence wi ll continue upon
subseq uen t veh icle start -ups as long as the ma l­
function exists.
When the malfunct ion i ndicator is ill uminated,
the system m ay not be ab le to detec t or sig nal
l ow tire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, incl uding the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your vehicle to ensu re
that t he replacement or alternate ti res and
wheels allow the TPMS to cont inue to func tion

Care and cl eaning
- 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
c reases the risk of an acc ident. The brakes
must be d ried first w ith a few careful b rake
applica tions.
@ Note
- If you wash the veh icle in an automatic car
wash, you m ust fold the exte rior m irrors i n
to reduce the risk of damage to the mirrors.
Power folding exte rior m irro rs* must o nly
be fo lded in and out using the powe r folding
funct ion .
- To reduce t he risk of paint damage , do no t
wash the vehi cle i n direct sunlig ht. - T
o red uce the risk of damage to the s urface,
do not use insect removing sponges, kitchen
sponges o r similar items .
- Matte finish painted vehicle components:
- To reduce the r isk of damage to the sur-
face, do not use pol ish ing 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
f inish paint. The paint could be damaged
when the stickers or magnets a re re­
moved.
@ For the sake of the environment
Only wash the veh icle in facilities spec ially de­
s igned for that pu rpose. This will reduce the
r isk of dirty wate r contam inated with o il from
en te ring the sewe r system.
