-Have you r vehicle maintained properly
and in accordance with the service rec­
ommendat ions in your Warranty
& Main­
tenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the Emission Control Sys­
tem and could lead to damage.
Sporty driving
Warming up and cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv ­
ing.
When warming up, the vehicle is driven at a maximum engine speed of
6000 RPM
(Vl0 engine) or 7000 RPM (V8 engine) in or­
der to raise the engine oil temperature to a minimum of
140 °F (60 °(). The tires also on­
ly reach their full road holding capability once
they have warmed up .
The cooling fan can continue to run in your ve­ h icle after the engine is switched
off. H owev­
er, driving the vehicle to cool it down is part ic ­
ularly important. During sporty driving, the
engine and brakes, the exhaust system, and
the t ransm ission all become ex treme ly hot.
Before you park the vehicle, you shou ld d rive
it for a few mi les/kilometers at light load in
the low rpm range to allow it to coo l down .
Driving on a track
Before you take your vehicle out on a track,
ensure that it is in perfect condition. For ex­
ample, you should check the tire tread and the brake pads . It is best to increase t ire pressure
by about 0 .3 bar .
When driving on a track, oil consumption may be somewhat higher than in "normal" opera­
tion ¢page
180.
You shou ld definitely inspect your vehicle af­
ter subjecting it to severe condit ions. Are the
brake pads OK? Is there anything unusual
Dri vin g and en vironm ent 159
about the ti res, including the inner and outer
sidewa lls (e.g . tread, blistering)? Are the air
intakes free of leaves and tire dust? Is the o il
l evel OK?
Your authorized Audi dea ler or qua lified work­
shop will be happy to undertake an inspection
before and after use on the race track.
(D Tips
- Some race tracks (e.g . steeply banked
t u rns) may affect the response of the
ESP .
- When driven on a race track, all vehicle
parts are severe ly stressed. This can re ­
sult in increased wear.
Operation and maintenance
Fuel economy, env ironme nta l impact, and
wear on your eng ine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
By having your ve hicle reg ularly se rv iced by an
authorized Aud i dea ler helps to ens ure that i t
r uns properly and econom ica lly. The condition
of your veh icle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
con sumptio n.
The amount o f oi l used is re lated to engine
load and speed .
It is normal fo r the oil consump tion of a new
engine to reac h its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 mi les
(5,000 kilometers) before you can p rope rly
assess oil consumpt ion.
This also app lies to fue l cons umption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service

162 Cleaning and protection
Hand washing
When washing your vehicle by hand, first soft­
en the dirt with copious amounts of water and
rinse it
off as best you can.
Then clean the vehicle using a soft
sponge, an
auto glove or a low-pressure wash brush.
Work from the top down to the bottom, start­
ing with the convertible top
¢ page 163. Use
a
shampoo only for v ery stubborn dirt.
Rinse the sponge or auto glove thoroughly at
frequent intervals.
Clean the wheels, door sills and similar areas last. Use a separate sponge for this.
_& WARNING
-Car washes with conveyors can damage
the vehicle tires, which could cause the tire to lose pressure suddenly while driv­
ing and put you at risk for an accident.
Do not use car washes with conveyors.
- Switch
off the ignition when you wash
your vehicle to avoid an accident.
- Protect your hands and arms from sharp
metal edges when you clean the under­
body, the inside of the wheel wells or the
wheel covers to avoid cutting yourself.
- When washing your vehicle in the winter :
Moisture and ice in the brake system can
affect the brakes.
- Never wash tires with a jet that sprays
water in a direct stream . This could cause
invisible damage to the tires and weaken
them, even if the spray is from a relative ­
ly long distance and for a short time .
Damaged and weakened tires can fail
and cause accidents and personal injury.
(D Note
- Never drive your vehicle through any au ­
tomatic car wash that fails to provide ei­
ther sufficient clearance for your vehicle
or sufficient track width for your tires. Risk of expensive damage to the vehicle's
underbody , tires, and rims!
- As described in your Warranty
& Mainte­
nance booklet, damage or malfunction due to misuse of the vehicle or failure to
operate the vehicle in accordance with
the
instructions of this Owner's Manual
will not be covered under warranty.
- Fold the exterior mirrors flat - there is a
risk of damaging the exterior mirrors .
Power folding exterior mirrors must not
be folded in or out by hand. Use the pow­
er function!
- Do not wash the vehicle in direct sun­
light. You may damage the paint.
- Do not use sponges designed to remove
insects, rough kitchen sponges, or simi­
lar products. You risk damaging the
paint surface.
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never clean the head­
lights with a dry cloth or sponge . Use a
wet cloth or sponge .
It is best to use
soapy water.
- Never clean tires using a nozzle that
sprays water in a direct stream. Damage
can occur even with a relatively long
spraying distance and for a very short
time.
- To avoid damaging your vehicle, always
make sure that there is sufficient dis­
tance between the spray head and soft materials like rubber hoses, plastic parts
and sound-deadening materials. Never
aim the spray head at the same point for
a long time. This also applies to cleaning
headlights and painted bumpers. Re­
member: the closer the nozzle is to the
surface of the material, the greater the
stress on the material.
- Never clean the convertible top using a
power washer.
@) For the sake of the environment
Wash your vehicle only at specially de­
signed facilities. They can prevent any dirty
water contaminated by oil from entering
the waste water. In certain areas washing
a car outside of such facilities is not per­
mitted.

176 Checking and filling
thick rag over the cap when you open the coolant reservoir .
-If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­ partment could start a fire .
- Keep an approved fire extinguisher im ­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of R tronic to "N"
(Neutral); put manual transmission in
Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get ­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­
ing hot parts . Tie back hair before
starting, and wear no clothing that will
hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&. .

190 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those standard items which may be rep laced)

ve hicle manufacture r for a tire of a designated
si ze that has not been dr iven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure i s measu red or adjusted. -
If you notice un usua l vibration or if the
veh icle pulls to one side when driv ing, a l­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.
Curb weight
means the we ight of a motor ve hicle w ith
standard equipment includ ing the max imum
capa city of fuel, o il, and coolant, a ir cond i­
ti on ing and addi tional weig ht o f option al
equipmen t.
Extra load tire

LO AD", or "RF" on t he sidewall.
Gross Axle Weight Rating ( "GAWR ")
means the load-carry ing capacity of a s ingle
axle system , measured at the tire-ground in­
te rfaces .
Gross Vehicle Weight Rating ( "GVWR ")
means the maximum total loaded we ight of
the vehicle.
Groove
means the space between two adjacent tread
ribs .
Load rat ing (code )
means the maximum load that a tire is rated
to carry fo r a given inflation press ure. Yo u

196 Tires and wheels
wheels you have to adjust the tire pressures
on all wheels.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RI] appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability .
- Incorrect tire pressures and/or underin­ flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle .
The applicable pressure values are locat­
ed on a sticker on the driver's side 8-pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure monitoring system can work cor­
rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
the function of the tire pressure monitor­
ing system .
- Always inflate tires to the recommended
and correct tire pressure before driving
off .
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the tires will wear prematurely and the
vehicle will not handle well. -
If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the tire pressure and add
air as required .
(D Note
Driving without valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also increase the
fuel consumption .
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 also damage important parts of the
vehicle and can lead to sudden tire failure, in­ cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle . These
load limits are technically referred to as the
vehicle 's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs. (68 kg) for each
passenger at a designated seating position
and the total weight of any luggage in the ve-
hicle. ..,_

204 Tir es and whe els
eq uip all four wheels on your vehicle with cor ­
rectly fitted winter tires or all-season tires,
when winter road conditions are expected. This a lso improves the vehicle's braking per­
formance and reduces stopping distances.
Summer tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must always be fitted
on all four wheels.
Compat ible tire pressure mon itor ing sensors
must be installed on all fou r winter tires for
the tire pressure monitoring system to func­
tion proper ly ~
page 201 .
Ask your authorized Aud i dea ler or qualified
wo rkshop for permitted
winter tir e sizes. Use
only radia l winter tires .
W inter t ires lose the ir effectiveness when the
tread is worn down to a depth of 0.157 inch
(4 mm) .
Only drive with winter tires under winter con­
d itions . Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
Please always remember that w inte r tires may
have a lower speed rating than the t ires origi­
na lly installed on your veh icle at the t ime i t
was manufactured. Please see
r:!> page 200 ,
Speed roting (letter code) for a list ing of the
speed rating letter codes and the maximum
speed at which the tires can be driven.
The speed ra ting letter code
(~ page 191) is
on the s ide wall of the tire
r::!> poge 199.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
im um speed . Always know the maxim um
speed before driving off. Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
tires leading to an accident and serious
personal in ju ry to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your veh icle
were designed can cause t ire failure in­
cluding a blowout and sudden deflation,
l oss of cont ro l, crashes and ser ious per­
sonal injuries. Have wo rn o r damaged ti res
r eplaced immediately.
- W inte r ti res have maxim um speed rating
that may be lower than your vehicle 's
maximum speed.
- Never drive fas ter than the speed for
which the win ter or othe r ti res installed
on yo ur vehicle are rated.
A WARNING ~
A lways ad just your driving to the road and
traffic condit ions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive veh icle
handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
~ For the sake of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
S now cha ins may be fitted only to the rea r
whee ls, and o nly to certa in tire sizes . Ask your
autho rized Aud i dea le r o n whi ch tire sizes
snow c hains ca n be used.
T he snow chains must have low-profile links
and must not be t hicker than 0 .53 inch
(13 .5 mm), in cl ud ing the lock.
Remove wheel center covers before putt ing
snow c ha ins on your vehicle~@ . For safety
reasons cover caps must then be f itted over

soon as possible, and inflate them to the
proper pressure. Driving on a significant ly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation a l­
so reduces fuel efficiency and tire tread l ife,
and may affect the veh icle 's handling and
stopping ab ility.
Please note that the TPMS is not a substitute
for proper t ire maintenance, and it is the dr iv­
er's responsib ility to ma inta in correct t ire
p ress ure , even if under- inflation has not
reached the leve l to t rigger illumination of the
TPMS low tire pressure telltale .
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not ope rating properly. The
TPMS malfunc tion indica to r i s combined wi th
the low t ire p ressu re tell ta le. When the sys ­
tem detec ts a malf unct ion, the te lltale will
flash for approximately one minute and then remain continuo usly ill uminated . This se­
q uence will cont inue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
When the malfunction indicator is ill uminat ­
ed, the system may not be able to detect or
signa l low t ire pressure as intended . TPMS
malfunct ions may occ ur for a variety of rea­
sons, including the ins talla tion of replace­
ment or alternate tires o r whee ls on the veh i­
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the TPMS malfunct ion
t ellta le afte r replacing one o r more t ires or
wheels o n your veh icle to ensure tha t the re­
p lacemen t or a lternate tires and wheels allow
the TPMS to continue to function properly .
Introduction
The tire pressure monitoring system monitors
air pressure in all four road wheels while the
vehicle is moving .
As soon as the tire pressu re mo nitor ing sys­
tem senses a s ignificant loss o f air pressure in
one or severa l ti res, text messages and yellow
symbo ls appear in the instr ument cluster dis ­
p lay to alert the driver. The
[al warning light
Tire s an d wheel s 207
in the instrument cluster comes on when the
ti re is significant ly underinflated
Q page 34.
The wa rni ng lig ht [al also illu minates i n the
case of a system mal fun ct io n.
Be aware that t ire pressure is a lso dependent
o n the tempe ratu re of the t ire. For eve ry 18 ° F
(10 °C) incre ase in tir e te mper ature, tire pres­
s u re inc reases by about 1.5 psi (0 .1 bar). The
ti re warms up while the vehicle is moving and
ti re p ress ure rises . So you sho uld ad just tire
pressure only when they a re
cold, when the
temperature of the tires is roughly the same
as the ambient a ir temperature.
In order to keep the tire press ure monitoring
system p roperly ca librated, t ire press ure on
all four tires sho uld be checked at regu lar in­
terva ls.
The tire pressure is shown on the label located
on the dr iver's side B-pillar (v is ib le when the
door is open) .
A WARNING
When the tire pressure mo nitoring system
war ning light is lit , one o r more of your
tires is s ignificantly under-infla ted . You
shou ld stop and check your tires as soon as
pos sib le, and in flate t hem to the proper
p ress ure a s in dic ate d on the ve hicle's ti re
p ress ure lab el
¢page 19 3. D riving on a
significantly under -inflated ti re causes t he
tire to over heat and can lead to tire failure .
Under-inflat ion also is like ly to impair the
vehicle's handling and stopping ab ility.
@ For the sake of the environment
D riving wit h un der -inflated tires red uces
fuel efficiency an d tire t read life.
(D Tips
- E ach tire should be chec ked monthly
w hen the tem perature of the tires is
about the same as amb ient a ir tempera­
t u re and set to the recommended infla­
tion pressure as specified on the tire
pressure label
