& WARNING
-Do not press the accelerator pedal inad­
vertently when the vehicle is stationary and the engine is running and a gear is
selected. Otherwise the vehicle will start
to move immediately and could result in
a crash.
- If the power supply fails, the released
parking brake can no longer engage. In
this case, park the vehicle on level ground and secure it by placing these­
lector lever in the P position (automatic
transmission). See your authorized Audi dealer or qualified repair facility.
(D Note
If the symbol . in the display or the indi­
cator light. (USA models)/ . (Canada
models) in the instrument cluster flashes,
there is a malfunction in the brake system.
Please refer to the detailed description of
the indicator lights¢
page 18.
-If the indicator light . (USA models)/
• (Canada models) or
Ill turns on,
there may be a malfunction in the park­
ing brake ¢
page 19.
(D Tips
-You can set the parking brake at any time
-even with the ignition turned
off. To re-
lease the parking brake, the ignition
must be turned on and the brake pedal
must be pressed.
- If driver 's door is opened while the igni­
tion is switched on, the parking brake
sets automatically. This prevents unin­
tended rolling of the vehicle .
- Occasional noises when the parking
brake is set and released are normal and
are not a cause for concern.
- When the vehicle is parked, the parking
brake goes through a self -test cycle at
regular intervals. Any noises associated
with this are normal.
- If there is a power failure, the parking
brake will not set if it is released, and it
will not release if it is set ¢,&. . See your

.. 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.
& WARNING ~ -
-Always take the vehicle key with you
when leaving the vehicle, even for a short period of time. This applies partic­
ularly when children remain in the vehi­
cle. 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
accident .
- No one should remain in the vehicle
when it is locked, especially children.
Locked doors make it more difficult for
emergency workers to get into the vehi­
cle, which puts lives at risk.
Starting from a stop
The start assist function ensures that the
parking brake is released automatically upon starting.
Stopping and applying the parking brake
.. Pull the switch@¢ page 76, fig . 68 to set

78 Driving
When stopping at a traffic signal or stopping in city traffic, the parking brake can be ap­
plied. The vehicle does not have to be held
with the brake pedal. The parking brake elimi­ nates the tendency to creep when a selector
lever position is engaged . As soon as you
press the accelerator pedal, the parking brake
releases automatically and the vehicle starts
to move.
Starting on slopes
When starting on inclines, the hill start assist
prevents the vehicle from unintentionally roll­
ing back. The braking force of the parking
brake is not released until sufficient driving
force has been built up at the wheels.
(D Tips
For safety reasons, the park ing brake is re­
leased automatically only when the driv­
er 's safety belt is fastened and the driver 's
door is locked.
Emergency braking function
This is used if the convention brake system
fails or locks up.
~ To brake your vehicle in an emergency, pull
the @switch
¢ page 76, fig. 68 and hold it
pulled.
~ As soon as you release the@ switch or ac-
celerate, the braking process stops.
Pulling and holding the @switch while driv­
ing at a speed of about 2 mph (3 km/h) or
higher initiates the emergency braking func­
tion. The vehicle is braked at all four wheels by activating the braking hydraulics. The brake
performance is similar to heavy braking.¢.&
To help prevent activating the emergency braking by mistake, an audible warning tone
(buzzer) sounds when the @switch is pulled.
E mergency braking stops as soon as the@
switch is released or the accelerator pedal is pressed.
A WARNING
Emergency braking should only be used in
an emergency, when the normal brake
pedal has failed or the brake pedal is ob­
structed . 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 corners and when road or
weather conditions are bad, a full brake
application can cause the vehicle to skid or
the rear end to break away, which increas­
es the risk of an accident.
Hill hold
Applies to vehicles: wit h Hill Hold
Hill hold makes it easier to start on hills.
Requirement: The driver door must be closed
and the engine must be running.
The system is activated when the brake pedal
is pressed while the vehicle is stationary.
To prevent the vehicle from rolling back when
starting, the brake power is held for a brief
moment after releasing the brake pedal. Dur­
ing this time, you can easily begin to move
your vehicle.
A WARNING ......_
- The intelligent technology of Hill Hold
cannot overcome the limitations im­
posed by natural physical laws. The in­
creased comfort offered by Hill Hold
should not cause you to take safety risks .
- Hill Hold cannot hold the vehicle in all
hill start situations (for example, if the
ground is slippery or icy).
- If you do not begin moving immediately
after releasing the brake pedal, the vehi­
cle could begin to roll backward under
certain circumstances. Press the brake
pedal or set the parking brake immedi­
ately.
- If the engine "stalls", press the brake
pedal or set the parking brake immedi­
ately.

Introduction
Applies to vehicles: with Audi pre sense basic or Audi pre
sense front
Within the limits of the system, pre sense ba­
sic and pre sense front can initiate steps to
protect vehicle occupants in certain danger ­
ous situations.
Critical driving situations can be recognized by
the pre sense front via a network of different
vehicle systems and can take steps to prepare
the vehicle occupants for a potential collision.
The pre sense front works with a radar sensor
and a video camera*.
It also functions within
the limits of the system when adaptive cruise
control* is switched
off.

Audi pre sense basic
Descript ion
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activat­
ed at a speed of 10 mph (30 km/h) or higher.
The following functions can be triggered un­
der certain conditions within the limits of the
system:
- Tensioning of the safety belts (for example,
during heavy braking) : The front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to trigger again .
- Closing the windows and the sunroof* (for
example, when over- or understeering): The
windows and the sunroof" close until there is only a small gap open. Audi drive select:
The deployment time is
adapted in dynamic mode.
A WARNING
-The pre sense basic cannot overcome natu- ral physical laws.
It is a system designed to
assist and it cannot prevent a collision. Do not let the increased safety provided
tempt you into taking risks. This could in­
crease your risk of a collision.
- The system can deploy incorrectly due to system-specific limits .
(D Tips
-Certain pre sense basic functions switch
off when ESC is switched off (sport
mode) or when driving in reverse .
- The pre sense basic functions may not be
available if there is a malfunction in the
ESC system or the airbag control mod­
ule .
- Note that with pre sense basic, the rever­
sible safety belt pretensioner on the
front passenger's side deactivates when
the front passenger's a irbag is deactivat­
ed.
Audi pre sense front
Description
Applies to vehicles: with Audi pre sense front or Audi
adapt ive cru ise control
Pre sense front informs you if the distance to
the vehicle ahead falls below the safe distance
for an extended period of time. It can warn of a possible collision and initiate braking ma­
neuvers, within the limits of the system .
When detected in time, the system can assess
dangerous situations where an object ahead
brakes suddenly or if your own vehicle is trav­
eling at a high speed and approaching an ob ­
ject that is moving more slow ly . If detection is
not possible, then pre sense front does not re ­
act.

When parking on a level surface, simply place
the selector lever in the P pos ition. On in­
clines , activate the parking bra ke first and
then move the selector lever to the P pos it ion
¢ page 76 . This prevents the locking mecha­
nism from being loaded too heavi ly and will
make it easier to move the selector lever out
of the P position.
A WARNING
- The vehicle can also roll when the engine
is stopped.
- Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine running while in gear. If you must leave
your veh icle when the engine is running,
set the parking brake and move these­
lector lever to the P position .
- Power is still transferred to the wheels
when the engine is runn ing at idle. To
p revent the vehicle from "c reeping", you
must keep you r foot on the brake when
the engine is running and the selector lever is in the D, So r R position or "tip­
tronic" mode is selected .
- Do not inadvertently press the ac celera­
tor peda l when the vehicle is stationary.
Otherwise the vehicle wi ll start to move
immediate ly, even if the parking brake is
set. Th is could result in a crash.
- Do not press the accelerator pedal when
changing the se lector lever position
while the veh icle is stationary and the
engine is running.
- Never engage the se lector level positions
R or P while dr iv ing. It could cause a
crash .
- Before driving down a steep slope, re­
duce your speed and shift into a lower
gear with "tiptronic" .
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill . Constant braking causes the
brakes to overheat and substantially re­
duces braking pe rformance, increases
b rak ing distan ce or c auses complete fa il­
ure of the brake system.
- I f you must stop on an in cl ine, always
hold the vehicle i n place with the foot
brake or park ing brake to p revent it from
rolling back .
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto ­
matica lly when it becomes too hot from

the overload. The ml indicator light
turns on and a message appears
Q page 111 when the clutch is overload­
ed .
-If the engine must remain running, never
have any driving position engaged when
checking under the hood . Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
Q page 210. Otherwise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake set.
(y Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear
is selected. This can cause the automatic
transmission to overheat and can dam­
age it. Set the parking brake or press the
brake pedal to prevent the vehicle from
rolling.
- Allowing the vehicle to roll when the en­
gine is stopped and th@ selector lever is
in the N position will damage the auto­
matic transmission because it is not lu­
bricated under those circumstances .
- The transmission can overheat and be
damaged under certain driving and traf­
fic conditions such as frequent starts,
creeping for a long time , or stop-and-go
traffic. When the
ml or . indicator
light turns on, stop the vehicle at the
next opportunity and let the transmis­
sion cool

Hill descent control
App lies to vehicles : wi th S tronic tra nsmi ssio n
Hill descent control assists the driver when
driving down inclines .
Hill descent control is activated when these­
lector lever is in the D or S position and you
press the brake pedal. The transmission auto ­
matically selects a gear that is suitable for the
incline. Hill descent control tries to maintain
the speed achieved at the time of braking,
within physical and technical limitations. If
may still be necessary to adjust the speed
with the brakes . Because hill descent control
cannot sh ift down farther than 3rd gear, it
may be necessary to shift into tiptronic mode
in very steep areas. In this case, shift into 1st
or 2nd gear in tiptronic mode to use the en­ gine's braking force to relieve the brakes .
Hill descent control switches off once the in­
cline levels out or you press the accelerator
pedal.
On vehicles with a cruise control system*
Q page 79, hill descent control is also activat­
ed when the speed is set.
A WARNING
-
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the brakes .

What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver 's ability to concentrate on the rood
without being distracted.
The driver is respons ible for the safety of the
vehicle and all of its occupants.
If your ability
to drive is impa ired, safety r isks for everybody
in the vehicle increase and yo u also become a
hazard to everyone else on the road
r:::;, &,.
Therefore:
• Do not let yourself be dis tracted by passe n­
gers or by using a cellular telephone.
• NEVER drive when your driving ability is im­
paired (by medications, alcohol, drugs, etc.).
• Observe all traffic laws, rules of the road
and speed limits and plain common sense.
• ALWAYS adjust your speed to road, traffic
and weather condit ions .
• Take frequent breaks on long trips . Do not
dr ive for more than two hours at a stretc h.
• Do NOT drive when you are t ired, under
pressure or when you are st ressed.
A WARNING
-Impaired dr iving safety increases the risk
of ser ious personal injury and death when­
ever a vehicle is being used.
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig . 109 Correct seat ing posit ion
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
following position:
.,. Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floor
while keeping your knee(s) slightly bent
r:::;,A .
.,. Adjust the angle of the seatback so that it is
in an upright position so that your back
comes in full contact with it when you drive.
• Adj ust the steering wheel so that there is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and your breast
bone
c:::> fig. 109 . If not possible, see your au­
thorized Audi dealersh ip about adaptive
equ ipment .
.. Adjust the steering wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face.
• Grasp the top of the steering whee l with
your elbow(s) slightly bent .
• For adjustable head restraints: Adjust the
head restraint so the upper edge is as even
as possible with the top of your head. If that..,_

is not possible, try to adjust the head re­
straint so that it is as close to this position
as possible. Move the head restraint so that
it is as close to the back of the head as pos­
sible.
.. Fasten and wear safety belts correctly
Q page 134.
.. Always keep both feet in the footwell so
that you are in control of the vehicle at all
times.
For detailed information on how to adjust the
driver's seat, see
Q page 54 .
.&, WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds. To help
reduce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breast­
bone and the steering wheel.
- Always adjust the driver's seat and the
steering wheel so that there are at least
4 inches (10 cm) between the knees and
the lower part of the instrument panel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal injury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag in­
flates.
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver's airbag to protect you in a
collision.
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air­
bags are located.
-
Driving safety 123
-Before driving, always adjust the front
seats properly and make sure that all passengers are properly restrained.
- For adjustable head restraints: before
driving, always also adjust the head re­
straints properly.
- Never adjust the seats while the vehicle is moving. Your seat may move unexpect­
edly and you could lose control of the ve­ hicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests are tilted back, the greater the risk of in­
jury due to incorrect positioning of the safety belt and improper seating posi­
tion.
- Children must always ride in child seats
Q page 166. Special precautions apply
when installing a child seat on the front
passenger seat ¢
page 140.
Proper seating position for the front
passenger
The proper front passenger seating position
is important for safe, relaxed driving.
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the seat for the front
passenger to the following position:
.. Adjust the angle of the seatback so that it is
in an upright position and your back comes
in full contact with it whenever the vehicle is
moving.
.. For adjustable head restraints: adjust the
head restraint so the upper edge is as even
as possible with the top of your head. If that
is not possible, try to adjust the head re­
straint so that it is as close to this position
as possible
¢ page 125. Move the head re­
straint so that it is as close to the back of
the head as possible .
.. Keep both feet flat on the floor in front of
the front passenger seat.
.. Fasten and wear safety belts correctly
