Requirement: the driver's door must be closed,
the driver's safety belt must be latched and the
parking brake must be set.
.,. To start driving and release the parking brake
automatically, press the accelerator pedal as
usual.
In addition to releasing the parking brake auto­
matically, other convenience and safety functions
are available when you start driving
¢page 74,
Starting to drive.
Preventing the automatic parking brake
release
The vehicle could begin rolling unintentionally,
depending on the hill or if towing a trailer.
.,. To prevent the parking brake from releasing au­
tomatically, pull and hold
the(®) switch and
press the accelerator pedal. The parking brake
remains set and prevents the vehicle from roll­
ing backward.
.,. You can release the C®l switch again once you
are sure that you are giving enough driving
force to the wheels by pressing the accelerator pedal.
Emergency braking function
You can use the emergency braking function in an
emergency situation, or if the standard brake op­
eration malfunctions or is disabled.
.,. Pull and hold the®) switch.
.,. As soon as you release the (®) switch or acceler-
ate, the braking stops.
Pulling and holding the
C®) switch while driving
the vehicle activates the emergency braking func­
tion. The vehicle is braked at all four wheels by
activating the hydraulic brake system. The brak­ ing effect is similar to heavy
braking¢&_ .
To reduce the risk of activating the emergency
braking by mistake, a warning tone (buzzer)
sounds when
the®> switch is pulled. Emergency
braking stops as soon as
the®) switch is released
or the accelerator pedal is pressed.
Parking
.,. Press the brake pedal to stop the vehicle.
Driving
.,. Pull the®> switch to set the parking brake .
.,. Place the selector lever in the P position.
.,. Turn the engine off¢&_ .
.,. Turn the steering wheel when parking on in­
clines so that the wheels will roll into the curb
if the vehicle starts moving.
A WARNING
-
- Do not press the accelerator pedal inadver­
tently if a gear is selected when the vehicle
is stationary and the engine is running. Oth­
erwise, the vehicle will start to move imme­
diately and this could result in an accident.
- Emergency braking should only be used in
an emergency, when the normal brake pedal
has failed or the brake pedal is obstructed.
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which
increases the risk of an accident.
- If the power supply fails , you cannot set the
parking brake if it is released . In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- If you leave the vehicle, switch the ignition
off and take the vehicle key with you. This
applies particularly when children remain in
the vehicle. Otherwise children could start
the engine, release the parking brake or op­
erate electrical equipment such as power
windows, which increases the risk of an acci­
dent.
- No one should remain in the vehicle when it
is locked - especially children . Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D Tips
When stopping at a traffic signal or stopping
in city traffic, you can set the parking brake
manually . The vehicle does not have to be

Intelligent Technology
driving too close to objects ahead . The ESC
and its integrated systems cannot always prevent coll isions
-there is still a risk of ac­
cidents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such as ice and snow . The drive wheels can spin
even when these control systems are instal-
Switching on /off
led and this can affect driving stability and
increase the risk of a collision.
(D Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

Applies to: vehicles wit h all wheel drive
In oil wheel drive, oil four wheels ore powered .
General information
In all wheel drive, the driving power is divided be­
tween all four wheels. This happens automatical­
l y depending on your driving behavior as well as
the current road conditions. Also see
c:> page 119, Electronic stabilization control
(ESC) .
A center differential distributes the driving power
variab ly to the front and rear axle. It works to­
gether with selective wheel torque control, which
activates when driving through curves
c:>poge 119. With the sport differential*, power
distribution to the rear wheels is variable and can
be adjusted w ith drive select
c:> poge 104 .
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow­
erful and has excellent driving characteristics
both under normal driv ing cond itions and on
snow and ice. Always read and fo llow safety pre­
cautions
c:> .&, .
Winter tires
By using all wheel drive, your vehicle has good
forward mot ion with standard tires in winter con­
ditions . However, in winter we recommend using
winter or all season tires on all four w heels, be­
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:> page 217, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used .
Avoid using tires with different tread depths
c:> page 208, New tires or wheels .
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain.
Intelligent Technology
A WARNING
--
- Also, in veh icles with all wheel drive, adapt
your driving style to the current road and
traffic conditions . Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci­
dent.
- 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 be tempted to accelerate to a
high speed when the road is slippery, be­
cause t his increases the risk of an accident .
- Note that on wet streets, the front wheels
can "hydrop lane" if driving at speeds that
are too high. Unlik e front wheel drive
veh icles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty . This significantly improves the start ing ability
and increases the vehicle battery life.
(D Tips
- If you dr ive short distances frequently, the
veh icle battery may not charge enough
w hile driving. As a result, convenience func­
tions for electr ical equipment may be tem­
porarily unavailable.
- Th e vehicle battery w ill gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be reduced or
switched off.

New tires or wheels
Audi recommends having all work
on t ires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
know ledge and are eq uipped with
the required too ls and rep lace­
ment parts.
... New t ires do not yet have the

... Only use tires with the same de­
sign, size ( rolling circumfer ­
ence) , and as close to t he same
tread pattern as possible on a ll
four wheels .
...
Do not replace tires individually.
At least replace bo th tires on the

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¢ ,&..
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 .
Wheels
A WARNING
-Do not use steel rims that are
17 inches or larger. Other­
wise, damage to the vehicle and an accident could result.
-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.
