Driving dynamic

The all-wheel drive system is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre-
cautions > A\.
Quattro ultra
Applies to: vehicles with quattro ultra
If the driving situation does not require all wheel
drive, then the rear section of the drivetrain will
decouple and thus save fuel. The system con-
stantly determines and anticipates if all wheel
drive is needed. This allows the rear drivetrain to
recouple shortly before it is needed.

ZA WARNING
— Even in vehicles with all wheel drive, you
should adapt your driving style to the cur-
rent road and traffic conditions to reduce
the risk of an accident.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not drive too fast because this in-
creases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane’” if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the engine RPM does not increase
suddenly when the vehicle begins hydro-
planing. Adapt your speed to the road condi-
tions to reduce the risk of an accident.

Syed)
Applies to: vehicles with sport differential
The sport differential distributes the drive power
to the rear axle based on the situation. The goal
is a high level of agility and ability to accelerate
on curves. The vehicle is very responsive to steer-
ing. The settings depend on the selected Audi
drive select* mode.
t3] All-wheel drive: malfunction! You can con-
tinue driving. Please contact Service
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.

ized Audi Service Facility if the sport differen-
tial is faulty or malfunctioning. The repair
must be performed by trained personnel us-
ing the correct oil in order to ensure safety.


Electronic Stabilization
Control
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations, such as if the vehicle is oversteering or
understeering, or if the wheels are spinning.
The brakes are applied or the engine torque is re-
duced in order to stabilize the vehicle.
The following stabilization functions are integrat-
ed into the ESC, among others: >

Checking and Filling

Checking and Filling
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 > ©.
Audi recommends using premium gasoline with
minimum 91 AKI / 95 RON to achieve the rated
horsepower and torque.
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.
UNLEADED FUEL ONLY PREMIUM MIN. (R
+M)/2 93 / SUPER PLUS MIN. RON 98
Using premium plus gasoline with at least 93
AKI / 98 RON is recommended.
If no premium plus gasoline is available, you can
also use premium gasoline with 91 AKI / 95 RON.
However this does reduce the engine power
slightly.
254
@) 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, refueling at high-traf-
fic gas stations is recommended. 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 >

4K8012721BF
Checking and Filling

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, Audi recom-
mends 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.

> Insert the fuel pump nozzle all the way into the
fuel filler neck. Make sure it is seated correctly.
> 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.

> 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 ona label located on the inside of the fuel
filler door. For additional information on fuel, see
=> page 254.
For the tank capacity in your vehicle, refer to the
Technical Data > page 332.

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
Audi does not recommend transporting fuel
containers inside the vehicle. Fuel could leak
out of the container and ignite, especially dur-
ing 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

4K8012721BF
Checking and Filling



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.

@) 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.
@) Tips
The fuel filler door on your vehicle does not
lock if you lock the vehicle from the inside us-
ing the central locking switch.
@ Tips
Your vehicle is equipped with a misfueling
guard. It allows the vehicle to be fueled only
with
the correct fuel pump nozzle.
—Aworn or damaged nozzle or a nozzle that
is too small may not be able to open the die-
sel misfueling guard. If this is the case, try
turning the nozzle before inserting it in the
fuel filler neck, use a different fuel pump, or
see an authorized Audi dealer or authorized
Audi Service Facility for assistance.
—The misfueling guard does not open when
adding fuel from a fuel container. When re-
fueling with a reserve canister, you must use
the funnel stored in the luggage compart-
ment > page 257.
@) Tips
Applies to: vehicles with plug-in hybrid drive
- When inserting the fuel pump nozzle, make
sure that you do not press on the fuel filler
door opener @) with the fuel pump nozzle.
See the label in the fuel filler door @)
> fig. 158. Otherwise, a valve will close in
the fuel filler neck and fueling will stop even
if the tank is not full.
— You must vent the tank system again if you
press on the fuel filler door opener. The fuel
pump nozzle can stay in the fuel filler neck
when doing this. Vent the tank system by
pulling the EN) switch in the driver's door
again.
— If the engine turned off because the fuel
level was too low, then you may need to re-
fuel with up to 4.0 gallons (15 liters) of fuel
in order for the vehicle to detect the new
fuel level. Otherwise, the engine may not
restart.
— Fuel can age and may lead to problems
when starting. Audi recommends replacing
the fuel in your vehicle within six months.
