MMI, connect your cell phone to the MMI via
Bluetooth.
Handsfree
After you have connected your mobile device to
the MMI via Bluetooth, you can use the handsfree
system and operate telephone functions through
your MMI. You can make calls using the antenna
on your mobile device.

ZA\ WARNING
— Medical experts warn that mobile devices
can interfere with the function of pacemak-
ers. Always maintain a minimum distance of
about 7.9 inches (20 cm) between the mo-
bile device antennas and the pacemaker.
— Do not carry the mobile device in a pocket
directly over the pacemaker when the
phone is switched on.
— Switch the mobile device off immediately
if you suspect it may be interfering with
the pacemaker.
— Do not use the voice recognition system
=> page 104 in emergencies because your
voice may change in stressful situations. The
system may take longer to dial the number
or may not be able to dial it at all. Dial the
emergency number manually.
— Switch your mobile device off in areas where
there is a risk of an explosion. These loca-
tions are not always clearly marked. This
may include gas stations, fuel and chemical
storage facilities or transport vehicles, or lo-
cations where fuel vapors (such as propane
or gasoline vapor in vehicles or buildings),
chemicals or large quantities of dust parti-
cles (such as flour, sawdust or metal) may
be present in the air. This also applies to all
other locations where you would normally
turn your vehicle engine off.
— The demands of traffic require your full at-
tention. Always read the chapter > page 93,
Traffic safety information.

Fig. 172 Tether strap: proper routing and mounting (Ver-
sion B)
The tether strap anchor bracket is located behind
the front passenger's seat at the rear panel to
the engine compartment.
A tether is a straight or V-shaped strap that at-
taches the top part of a child restraint to special
anchorage points in the vehicle.
The purpose of the tether is to reduce the for-
ward movement of the child restraint in a crash,
in order to help reduce the risk of head injury that
could be caused by striking the vehicle interior.
Forward facing child restraints manufactured af-
ter September 1, 1999, are required by U.S. fed-
eral regulations to comply with new child head
movement performance requirements. These
new performance requirements make a tether
necessary on most new child safety seats.
Installing a child restraint that requires a top
tether without one can seriously impair the per-
formance of the child restraint and its ability to
protect the child in a collision. Installing a child

restraint that requires a top tether without the
top tether may be a violation of state law.

Improper installation of child restraints will
increase the risk of injury and death in a crash.
— Always follow the instructions provided by
the manufacturer of the child restraint you
intend to install in your Audi.
— Improper use of child restraint anchors (in-
cluding tether anchors) can lead to injury in
a collision. The anchors are designed to
withstand only those loads imposed by cor-
rectly fitted child restraints.
— Never attach two child restraint systems to
one tether strap or tether anchorage.
— Never use child restraint tether anchorages
to secure safety belts or other kinds of occu-
pant restraints.
— Never secure or attach any luggage or other
items to the tether anchors.
— Ifa tether or other strap is used to attach a
child restraint to the front passenger seat,
make sure that it is not so tight, that it caus-
es the weight-sensing mat to measure more
weight than is actually on the seat.
— The heavier weight registered can make the
Advanced Airbag System work as though an
adult were on the seat and deploy the Ad-
vanced Airbag when it must be suppressed
causing serious or even fatal injury to the
child.
— Never install a rearward facing child safety
seat on the front passenger seat unless the
PASSENGER AIR BAG OFF %; light comes
on and stays on. If the PASSENGER AIR
BAG OFF 3%; light does not come on and stay
on the inflating airbag will hit the child safe-
ty seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, door or roof. Have the
airbag system inspected immediately by
your authorized Audi dealer.
— Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions
require the top tether strap to be used.

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.
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.
() 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.
226
G) 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.

4S1012721BA
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.

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.

Checking and Filling

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 226.
For the tank capacity in your vehicle, refer to the
Technical Data > page 290.

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.

ZA WARNING
The vehicle must not be refueled with a re-
serve canister due to the risk of fire.


@) 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.
228
— Never insert any portable nozzles, funnels
or after-market containers into the fuel fill-
er neck.
— Do not pry open the fuel filler neck forceful-
ly or press against it with foreign objects to
open the tank system.
@) 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
— If adverse weather conditions cause the fuel
filler door to freeze shut, press on the cen-
ter of the filler door with the heel of your
hand and then try opening it again.
— The fuel filler door on your vehicle does not
lock if you lock the vehicle from the inside
using 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 electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“p” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
