Fuel 
Types of gasoline 
The correct gasoline grade is stated on the inside 
of the fuel filler door. 
The vehicle is equipped with a catalytic converter 
and must only be driven with unleaded gasoline. 
Audi recommends using TOP TIER Detergent Gas- 
oline. For additional information on TOP TIER De- 
tergent Gasoline, visit www.toptiergas.com. 
The individual gasoline grades are differentiated 
by octane ratings. This value is given with (R 
+M)/2 equating to AKI or in RON. 
The headings below match the sticker in the fuel 
filler door (examples): 
UNLEADED FUEL ONLY MIN. (R+M)/2 87 
Regular / MIN. RON 91 Regular 
Use regular gasoline with minimum 87 AKI / 
91 RON > ©. 
UNLEADED FUEL ONLY PREMIUM MIN. (R 
+M)/2 91 / SUPER MIN. RON 95 
Using premium gasoline with minimum 91 AKI / 
95 RON is recommended. 
If premium gasoline is not available, you can also 
use regular gasoline 87 AKI / 91 RON. However 
this does reduce the engine power slightly. 
@) Note 
— Filling the tank just one time with leaded 
fuel or other metallic additives will cause 
permanent deterioration to the catalytic 
converter function. 
— When gasoline with an octane rating that is 
too low is used, high speeds or heavy engine 
load can lead to engine damage. 
@ Tips 
The vehicle may be filled with fuel that has a 
higher octane rating than what is required by 
the engine. 
Gasoline mixture 
Gasoline with alcohol or MTBE (Methyl-Tert- 
Butyl-Ether) 
You can  use unleaded gasoline mixed with alco- 
hol or MTBE (generally labeled as oxygenated 
compounds) as long as the fuel meets the follow- 
ing conditions: 
Gasoline with methanol content (methyl alco- 
hol or methanol) 
— Anti-Knock Index is at least 87 AKI 
—No more than 3% methanol 
— More than 2% solvent 
Gasoline with ethanol content (ethyl alcohol or 
ethanol) 
— Anti-Knock Index is at least 87 AKI 
—No more than 15% ethanol 
Gasoline with MTBE content 
— Anti-Knock Index is at least 87 AKI 
—No more than 15%  MTBE 
Gasoline adapted to the season 
Many gasoline fuels are adapted to the seasons. 
When the season changes, we recommend refu- 
eling at high-traffic gas stations. It is more likely 
that the gasoline will be suitable for the season 
there. 
() Note 
— Gasoline with methanol content that does 
not meet the specified conditions may cause 
corrosion damage and damage to plastic or 
rubber components in the fuel system. 
— Do not use gasoline that does not meet the 
specifications. 
— If you are unable to find out if a specific gas- 
oline mixture meets the specifications, ask 
the  gas station operator or their fuel suppli- 
er. 
— 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.

filler door 
  
    
  
  
Fig. 138 Fuel filler door with attached fuel cap 
The fuel filler door is unlocked or locked by the 
central  locking system. 
> Press on the left side of the fuel filler door to 
open > fig. 137. 
» Unscrew the tank cap counterclockwise. 
> Place the cap from above on the open fuel filler 
door > fig. 138. 
> 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 it to allow the rest of 
the fuel to finish dripping into the fuel tank. 
> Turn the fuel cap clockwise until you hear it 
lock. 
> Close the fuel filler door and then press on the 
left side until it latches.

bolted securely to the engine block, or  to 
the engine block itself. If the vehicle battery 
in the vehicle being jump started is not 
vented to the outside, there is a risk of ex- 
plosion  due to hydrogen gas. 
Gi) Tips 
Make sure that the connected jump start ca- 
bles have sufficient contact with metal. 
Towing 
erasure) 
You should only perform the steps that follow if 
you  have the necessary tools and technical ex- 
pertise. 
Towing requires a certain amount of practice.  Au- 
di recommends contacting a towing company to 
have the vehicle transported. 
You should only have your vehicle towed by an- 
other vehicle when disabled in exceptional cir- 
cumstances. Inexperienced drivers should not 
tow. 
Notes on towing 
When the engine is stopped, the transmission 
will not be sufficiently lubricated if traveling at 
high speeds and long distances: 
— The maximum permitted towing speed is 30 
mph (50 km/h). 
— The maximum permitted towing distance is 30 
miles (50 km). 
Additional information on towing with a tow 
truck 
The vehicle may only be towed with the front axle 
raised. Do not wrap any chains or cables around 
the brake lines. 
If the vehicle should be towed with the axle 
raised, then the ignition must be switched off to 
reduce the risk  of damage to the drivetrain. 
Tow bar and towing cable 
The vehicle can be towed with a tow bar or tow- 
ing cable. Both drivers should be familiar with 
248 
the special considerations when towing, especial- 
ly when using a towing cable. 
Always make sure the traction force does not ex- 
ceed the permitted level and  there are no shock 
loading conditions. There is always the risk of the 
coupling becoming overloaded when driving off- 
road. 
For the most safety and security, drive with a tow 
bar. You should use a towing cable only if a tow 
bar is not available. Use a towing cable made of 
synthetic elastic cable similar elastic material. 
  
ZA\ WARNING 
— Towing highly increases the risk of an  acci- 
dent, for example from colliding with the 
towing vehicle. 
—To reduce the risk of an accident, do not al- 
low anyone to remain inside the vehicle 
when it  is being transported by a tow truck 
or a special transporter. 
@) Note 
— If normal towing is not possible, for exam- 
ple if the transmission is faulty or if the 
towing distance is greater than 30 miles 
(50 km), then transport the vehicle on a 
special carrier. 
— If the vehicle is towed by a tow truck at the 
axle that is not permitted, this can cause se- 
vere damage to the transmission. 
— The vehicle must not be tow started for 
technical reasons. 
(i) Tips 
— If the power supply is interrupted, then it 
will not be possible to move the selector 
lever out of the "P" position. The parking 
lock must be released using the emergency 
release before towing the vehicle 
> page 85. 
— Switch Audi pre sense* off > page 123 when 
loading the vehicle onto a vehicle carrier, 
train,  ship, or other type of transportation, 
or when towing the vehicle. This can prevent 
an undesired intervention from the pre 
sense* system.
