Voice operation
General information
You can operate many functions in the vehicle
easily using voice commands.
Using the voice operation system effectively
> Speak clearly and distinctly at a normal volume.
Speak louder when driving faster.
> Emphasize the words in the commands evenly
and do not leave long pauses.
> Close the doors, the windows, and the sunroof*
to reduce background noise. Make sure that
passengers are not speaking when you are giv-
ing a voice command.
> Do not direct the vents toward the hands-free
microphone, which is in the roof headliner near
the front interior lights.
> Only the driver should speak to the system, be-
cause the handsfree microphone is aimed to-
ward this seating position.

ZA\ WARNING
— Direct your full attention to driving. As the
driver, you have complete responsibility for
safety in traffic. Only use the functions in
such a way that you always maintain com-
plete control over your vehicle in all traffic
situations.
— Do not use voice operation 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.

@ Tips
There are no voice guidance* prompts when a
dialog is active.

Driving dynamic

brake assist system may react with increased sen-
sitivity.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the drive wheels
begin spinning and adapts the power to the road
conditions. This makes it easier to start, acceler-
ate and drive up hills.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi-
tions have returned to normal.
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision, the vehicle is
braked by the ESC.
The vehicle does not brake automatically if:
— The driver presses the accelerator pedal, or
— the braking force generated by the pressed
brake pedal is greater than the braking force
that
would be initiated by the system, or
— the ESC, the brake system or the vehicle electri-
cal system are not functioning.

physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre-
vent collisions - there is still a risk of acci-
dents!
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
can affect driving stability and increase the



ZA WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural

risk of a collision.
G) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead to a
reduction in engine power.
— You may hear noises when the systems de-
scribed are working.
The So button is located above the selector lev-
er in the center console.

The ESC is automatically switched on when the
ignition is switched on. It may make sense in
some situations to limit the ESC so that the
wheels can spin:
— Rocking the vehicle to free it when it is stuck
— Driving in deep snow, on unpaved ground, or
with snow chains
— Driving downhill while braking on loose ground
— Driving with axle articulation
Limiting ESC (Offroad mode)
—To limit the ESD, press the £20 button briefly.

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
optimum 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 >

differently even if they are the
same size > A.
>If you would like to equip your
vehicle with a tire/rim combina-
tion that is different from what
was installed at the factory, con-
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur-
chase > A.
Because the spare tire® is differ-
ent from the regular tires instal-
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re-
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam-
aged by different wheel speeds.
For this reason, in case of emer-
gency, only use a spare tire* that
is the same circumference as the
regular tires.

Z\ WARNING
—Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
—For technical reasons, it is not
possible to use tires from oth-
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
—Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif-
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
—Only use tires that are more
than six years old when abso-
lutely necessary and drive
carefully when doing so.
—Do not use run-flat tires on
your vehicle. Using them when

AN WARNING
Please note the important safe-
ty precautions regarding tire
pressure > page 226 and load
limits > page 228.
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

@) Two people in the front, one person in the rear
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 >

Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature A BC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 217, fig. 149.
For example: Tread wear 200, Traction AA, Tem-
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
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
>A.
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.


Z\ 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 >
