Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicl e for long periods of
time
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradua lly scaled
back or sw itched off. Th is reduces energy use and
ensures the vehicle will be ab le to start after long
per iods of time

func tions, such as i nterio r lighting o r power seat
adjus tme nt, may no t be ava ilab le unde r certain
cir cumstances . These convenience func tions will
be available again once you switch the ignit ion on
and start the engine.
E ven when elec trical equipment is switched off,
the eq uipment can sti ll dr ain the vehicle ba ttery

A_ WARNING -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
- Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
254
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents .
-If you install wheel covers on the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.

-Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are
1/16 in (1.6 mm) high and are
spaced evenly around the tire per­
pendicular to the running direc­
tion¢
fig. 189. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the tread wear
indicators. Replace the tires with
new ones ¢.&.
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have

service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢ page 278.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­ cility to have the vehicle inspect­
ed.
.&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the risk aquaplaning when driving

Checking/correcting tire
pressure
•Check the tire pressure at least
once per month and also check it
before every long drive.
•Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
•Check the label ¢
fig. 191 for
the correct tire pressure based
on vehicle load.
•Correct the tire pressure if nec ­
essary .
•Vehicles with Tire Pressure Mon­
itoring System*: store the modi­
fied tire pressure in the Infotain­ ment system ¢

•Check the pressure in the emer­
gency tire*/spare tire*. A lways
maintain the maximum temper­
ature that is specified for the

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 ..,

a, a, ... N
" N ... 0
" V, a:,
150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle .
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 is limited.
The more passengers in the vehi­
cle or passengers who are heavier
than the standard weights as­
sumed 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 8-pillar
¢ page 256,
fig. 190.
&_ 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
Wheels
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
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
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 . Locate the statement "THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD .,.
259

Wheels
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 256, fig. 190.
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 256, fig. 190.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the "XXX" amount
equals 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
(1400-750 (5
X 150) = 650 lbs)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­ ceed the available cargo and luggage load capacity calculat­
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your ve-
260
hicle. Consult this manual to
determine how this reduces
the available cargo and lug­
gage load capacity of your vehi­
cle.
~check the tire sidewall
(¢ page 246, fig. 188) to deter­
mine the designated load rating
for a specific tire.
· Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them
¢ &..
_8. WARNING
-Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
¢ page 2 78, Finishing.
- Always keep the wheel bolts and the threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident .
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions . Be-
cause of their construction (width, compound, ..,.

tread pattern), summer tires provide less trac­
tion on ice and snow.
.,. Use w inter tires on a ll fo ur wheels.
.,. Only use win ter tires that are approved for your
vehicle.
... Please note that the maximum permitted
speed may be lower with winter tires ¢,& .An
authori zed Aud i dealer or authori zed Aud i Serv­
ice F acility can inform you about the maximum
permitted speed for your tires .
... Check the tire pressure after installing wheels
¢ page 256 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1 57 in (4 mm) . The character istics of winter
tires a lso decrease great ly as t he tire ages, re­
ga rdless of the remaining tread .
_& WARNING
-Never dr ive faste r than the maxim um per­
mitted speed for your t ires. This cou ld cause
the tires to heat up too much . Th is increases
the risk of an acc ident because it can cause
the tire to burst.
- Always adapt yo ur dr iv ing to the road and
traff ic conditions. Drive carefully and red uce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer ti res at the approp riate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, t ire wear and fuel
consumption .
You can also use all season tires instead of
w inter t ires . Please note that in some coun­
tries where w inter t ires are required, only
w inter t ires with the
& symbol may be per­
m itted.
Snow chains
-
Snow chains no t only imp rove the d riving in w in­
ter road conditions, but also the braking.
Wh eel s
... On ly install snow chains on the front wheels.
This applies a lso to vehicles with a ll wheel
drive* .
... Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
... Note the maximum speed of 30 mph (SO km/
h) . Note the local regulations .
Use of snow cha ins is only permitted with certa in
rim/tire comb inat ions due to technical reasons .
Check with an authorized Audi dealer or author­
i zed Audi Se rvice Facility to see if you may use
snow c hains.
You must remove the snow chains on roads with­ out snow . O therwise, you co uld impair driving
ability a nd damage the t ires .
_& WARNING
Using incor rect snow chains or install ing snow
ch ains incor rec tly c an resu lt in loss of veh icle
control, which increases the risk of an acci­
dent .
(D Note
-Snow chains can damage the rims/wheel
cove rs* if the chains come into direct con­
tact with them . Remove the wheel covers*
first. Use coated snow chains.
- Us ing snow chains that add more tha n O.S3
