Checking and Filling 
  
— Do not use any gasoline mixture whose 
composition cannot be identified. 
— Audi does not assume any responsibility for 
damage to the fuel system or for perform- 
ance problems caused by using gasoline 
mixtures different from those specified. 
This type of damage also does not fall under 
the New Vehicle Limited Warranty or under 
the emissions control system warranty. 
— If you notice a higher fuel consumption or 
poor handling or performance problems due 
to such gasoline  mixtures, we recommend 
fueling with unblended gasoline. 
Gasoline additives 
An important issue for many automobile manu- 
facturers is combustion residue in the engine 
that results from the  use of certain fuels. 
Although types of gasoline differ depending on 
the manufacturer, there are similarities. Certain 
substances in the gasoline may cause deposits in 
the engine. Additives in the gasoline that should 
keep the engine and fuel system clean do not all 
function equally. 
Audi recommends using TOP TIER Detergent Gas- 
oline. For additional information on TOP TIER De- 
tergent Gasoline, visit www.toptiergas.com. 
If you use incorrect fuels over a long period of 
time, the maximum engine performance may be 
impaired by combustion residue. 
@) Note 
— Damage or malfunctions caused by the use 
of incorrect types of gasoline are not cov- 
ered by the New Vehicle Limited Warranty. 
— Only gasoline additives that have been ap- 
proved by Audi may be used.

There is a malfunction in the fuel tank system. 
Drive to an authorized Audi dealer or authorized 
Audi Service Facility immediately to have the 
malfunction corrected. 
Fueling procedure   
Fig. 156 Right rear side of the vehicle: opening the fuel 
filler door 
    
Fig. 157 Fuel filler door with attached fuel cap 
The fuel filler door is unlocked or locked by the 
central  locking system. 
> Unlock the vehicle if necessary. 
> Press on the left side of the fuel filler door to 
open it > fig. 156. 
> Unscrew the tank cap counterclockwise. 
> Place the cap from above on the open fuel filler 
door > fig. 157. 
> Insert the fuel pump nozzle all the way into the 
fuel filler neck. 
> Begin fueling. Once the fuel pump nozzle turns 
off the first time, the fuel tank is full. Do not 
continue fueling, or else the expansion space in 
the tank will be filled with fuel. 
> After the fuel pump has switched off, wait five 
seconds before removing the nozzle to allow 
the rest of the fuel to finish dripping into the 
fuel tank.

Checking and Filling 
  
> Turn the fuel cap clockwise until it clicks  into 
place. 
> Close the fuel filler door and then press on the 
left side until it latches. 
The correct fuel type for your vehicle can be 
found on a label located on the inside of the fuel 
filler door. For additional information on fuel, see 
=> page 210. 
For the tank capacity in your vehicle, refer to the 
Technical Data > page 278. 
To reduce the risk of fuel leaking out or vapors 
escaping, make sure that the fuel tank is closed 
correctly. Otherwise the [gg indicator light will 
turn on. 
If the central  locking system malfunctions, there 
is a fuel filler door emergency release 
=> page 213. 
  
  
ZA\ WARNING 
Improper fueling procedures and improper 
handling of fuel can lead to explosions, fires, 
severe burns, and other injuries. 
— Do not smoke. Keep away from  open flames. 
— The ignition must be switched off when re- 
fueling. 
— Mobile devices, radio devices, and other ra- 
dio equipment should  always be switched 
off when refueling. Electromagnetic rays 
could cause sparks and start a fire. 
— If you do not insert the fuel pump nozzle all 
the way into the filler tube, then fuel can 
leak out. Spilled fuel can ignite and start a 
fire. 
— Never get into the vehicle when refueling. If 
there is an exceptional situation where you 
must enter the vehicle, close the door and 
touch a metal surface before touching the 
fuel pump nozzle again. This will reduce the 
risk of electrostatic discharge that can cause 
flying sparks. Sparks can start a fire when 
refueling. 
  
  
Z\ WARNING 
Transporting fuel containers inside the vehicle 
is not recommended. Fuel could leak out of 
the container and ignite, especially during an 
accident. This can cause explosions, fires, and 
injuries. 
— If you must transport fuel in a fuel contain- 
er, note the following: 
— Always place the fuel container on the 
ground before filling. Never fill the fuel 
container with fuel while it is inside or on 
the vehicle. Electrostatic discharge can oc- 
cur while  refueling  and the fuel vapors 
could ignite. 
— When using fuel containers made of met- 
al, the fuel pump nozzle must always re- 
main in contact with the container to re- 
duce the risk  of static charge. 
— Insert the fuel pump nozzle as far as pos- 
sible into the filler opening while refuel- 
ing. 
— Follow the applicable legal regulations in 
the country where you are driving when 
using, storing and transporting fuel con- 
tainers. 
— Make sure that the fuel container meets 
the industry standards, for example ANSI 
or ASTM F852-86. 
  
    
  
1) Depending on the engine and country 
212 
() Note 
— Remove fuel that has overflowed onto any 
vehicle 
components immediately to reduce 
the risk  of damage to the vehicle. 
— Never drive until the fuel tank is completely 
empty. The irregular supply of fuel that re- 
sults from that can cause engine misfires. 
Uncombusted fuel may enter the exhaust 
system and increase the risk of damage to 
the catalytic converter. 
@) For the sake of the environment 
— Do not overfill the fuel tank, or fuel could 
leak out when the vehicle is warming up. 
— Fuel should never enter the sewer system or 
come into contact with the ground.

— Have your  used engine oil recycled by bring- 
ing it to a used oil collection site or contact 
a gas station. 
Cooling system 
The engine cooling system is filled with a mixture 
of purified water and coolant additive at the fac- 
tory. This coolant must not be not changed. 
The coolant level is monitored using the B indi- 
cator light. However, occasionally checking the 
coolant level manually is recommended.

The amount of coolant additive that needs to be 
mixed with water depends on the climate where 
the vehicle will be operated. If the coolant addi- 
tive percentage is too low, the coolant can freeze 
and damage the engine.

@) Note 
— Before the start of winter, have an author- 
ized Audi dealer or authorized Audi Service 
Facility check if the coolant additive in your 
vehicle matches the percentage appropriate 
for the climate. This is especially important 
when driving in colder climates. 
— If the appropriate coolant additive is not 
available in an emergency, do not add  any 
other additive. You could damage the en- 
gine. If this happens, only use water and re- 
store the correct mixture ratio with the 
specified coolant additive as soon as possi- 
ble.

New tires or wheels 
Audi recommends having all work 
on tires or wheels performed by 
an authorized Audi dealer or au- 
thorized Audi Service Facility. 
These facilities have the proper 
knowledge and are equipped with 
the required tools and replace- 
ment parts. 
>New tires do not yet have the 
optimal gripping properties. 
Drive carefully and at moderate 
speeds for the first 350 miles 
(500 km) with new tires. 
> Only use tires with the same de- 
sign, size (rolling circumfer- 
ence), and as close to the same 
tread pattern as possible on all 
four wheels. 
>Do not replace tires individually. 
At least replace both tires on the 
same axle at the same time. 
> Audi recommends that you use 
Audi Original Tires. If you would 
like to use different tires, please 
note that the tires may perform >

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 Rating 
(“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- 
240 
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 on the driver’s side B- 
pillar respectively on the front 
end of the driver's door.

under controlled conditions on a specified gov- 
ernment test course. 
For example, a tire graded 150 would wear one 
and one half (1 1/2) times as well on the govern- 
ment course as a tire graded 100. 
The relative performance of tires depends upon 
the actual conditions of their use, however, and 
may depart significantly from the norm due to 
variations in driving habits, service practices and 
differences in road characteristics and climate. 
Traction 
The traction grades, from highest to lowest, are 
AA, A, B and C. Those grades represent the tire's 
ability to stop on wet pavement as measured un- 
der controlled conditions on specified govern- 
ment test surfaces of asphalt and concrete. A tire 
marked C may have poor traction performance 
oA. 
Temperature 
The temperature grades are A (the highest), B, 
and C, representing the tire's resistance to the 
generation of heat and its ability to dissipate 
heat when tested under controlled conditions on 
a specified indoor laboratory test wheel. 
Sustained high temperature can cause the mate- 
rial of the tire to degenerate and reduce tire life, 
and excessive temperature can lead to sudden 
tire failure > A. 
The grade C corresponds to a level of perform- 
ance which all passenger car tires must meet un- 
der the Federal Motor Vehicle Safety Standard 
No. 109. Grades B and A represent higher levels 
of performance on the laboratory test wheel than 
the minimum required by law. 
  
Z\ WARNING 
The traction grade assigned to this tire is 
based on straight-ahead braking traction 
tests, and does not include acceleration, cor- 
nering, hydroplaning or peak traction charac- 
teristics. 
      
244 
  
AN WARNING 
The temperature grade for this tire is estab- 
lished for a tire that is properly inflated and 
not overloaded. Excessive speed, underinfla- 
tion, or excessive loading, either separately or 
in combination, can cause heat buildup and 
possible tire failure. 
     
ZA\ WARNING 
Temperature grades apply to tires that are 
properly inflated and not over or underinflat- 
ed. 
       
Tire pressure monitoring 
system 
(1) General notes 
Each tire, including the spare (if provided), 
should be checked monthly when cold and inflat- 
ed to the inflation pressure recommended by the 
vehicle manufacturer on the vehicle placard or 
tire inflation pressure label. (If your vehicle has 
tires of a different size than the size indicated on 
the vehicle placard or tire inflation pressure la- 
bel, you should determine the proper tire infla- 
tion 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 tell- 
tale when one or more of your tires is significant- 
ly under-inflated. Accordingly, when the low tire 
pressure telltale illuminates, you should stop and 
check your tires as soon as possible, and inflate 
them to the proper pressure. Driving on a signifi- 
cantly under-inflated tire causes the tire  to over- 
heat and can lead to  tire failure. Under-inflation 
also reduces fuel efficiency and tire tread life, 
and may affect the vehicle's handling and stop- 
ping ability. 
Please note that the TPMS is not a substitute for 
proper tire maintenance, and it is the driver's re- 
sponsibility to maintain correct tire pressure, 
even if under-inflation has not reached the level 
to trigger illumination of the TPMS low tire pres- 
sure telltale.  
Page 247 of 296
8W1012721BB 
Wheels 
  
Your vehicle has also been equipped with a TPMS 
malfunction indicator to indicate when the sys- 
tem is not operating properly. The TPMS mal- 
function indicator is combined with the low tire 
pressure telltale. When the system detects a 
malfunction, the telltale will flash for approxi- 
mately one minute and then remain continuously 
illuminated. This sequence will continue upon 
subsequent vehicle start-ups as long as the mal- 
function exists. 
When the malfunction indicator is illuminated, 
the system may not be able to detect or signal 
low tire pressure as intended. TPMS malfunctions 
may occur for a variety of reasons, including 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 replacing one or 
more tires or wheels on your vehicle to ensure 
that the replacement or alternate tires and 
wheels allow the TPMS to continue to function 
properly. 
If the tire pressure monitoring indicator 
appears 
Applies to: vehicles with Tire Pressure Monitoring System in- 
dicator 
The tire pressure indicator in the instrument 
cluster informs you if the tire pressure is too low 
or if there is a system malfunction. 
Using the ABS sensors, the tire pressure monitor- 
ing system compares the tire tread circumference 
and vibration characteristics of the individual 
tires. If the pressure changes in one or more 
tires, this is indicated in the instrument cluster 
display with an indicator light @ and a message. 
If only one tire is affected, the location of that 
tire will be indicated. 
The tire pressures must be stored again each 
time you change the pressures (switching be- 
tween partial and full load pressure) or after 
changing or replacing a tire on your vehicle 
=> page 246. The tire pressure monitoring system 
only monitors the tire pressure you have stored. 
Refer to the tire pressure label for the recom- 
mended tire pressure for your vehicle 
= page 237, fig. 171. 
Tire tread circumference and vibration character- 
istics can change and cause a tire pressure warn- 
ing if: 
— The tire pressure in one or more tires is too low 
— The tires have structural damage 
— The tire was replaced or the tire pressure was 
changed and it was not stored > page 246 
— Tires that are only partially used are replaced 
with new tires 
Indicator lights 
If the @ indicator light turns on, there is a loss 
of pressure in at least one tire .> A\ Check the

while driving and the @ indicator light in the in- 
strument cluster blinks for approximately one 
minute and then stays on, there is system mal- 
function. Try to store the correct tire pressures 
=> page 246. In some cases, you must drive for 
several minutes after storing the pressures until 
the indicator light turns off. If the indicator light 
does turn off or turns on again after a short peri- 
od of time, drive to an authorized Audi dealer or 
authorized Audi Service Facility immediately to 
have the malfunction corrected. 
  
Z\ WARNING 
— If the tire pressure indicator appears in the 
display, reduce your speed immediately and 
avoid any hard steering or braking maneu- 
vers. Stop as soon as possible and check the 
tires and their pressure. 
— The driver is responsible for maintaining the 
correct tire pressure. You must check the 
tire pressure regularly. 
— Under certain conditions (such as a sporty 
driving style, winter conditions, or unpaved 
roads), the tire pressure monitoring system 
indicator may be delayed.
