SAFETYRRST--------------------------------------------------
Unfaste ning the safety belt
• Push the red release button on the
buckle. The belt tongue will spring out of the
buckle.
• Let the belt to wind up on the retractor as
you guide belt tongue to its stowed posi­
tion.
24 Belt
tensioner
The retractors for the three-point safety
belts are equipped with belt tensioners.
Sensors activate the belt tensioners in fron­
tal collisions when deceleration is high
enough. This tightens the belt and takes up
belt slack. Taking up the slack helps to re­
duce forward occupant movement during a
collision.
The belt tensioner can only be activated
once. The belt tensioner will not be acti­
vated if the safety belt is not in use.
Never let the belt remain extended
over a rear seat back that has been
folded forward. The rear belt ten­
sioner will be activated unnecessar­
ily in an accident and then have to be
replaced.
The belt tensioner will not activate in a light
frontal collision insufficient to actuate the
tensioner or in any side, rollover, or rear-end
collision. �W
ARNING
• Safety belt systems including
belt tensioners cannot be re­
paired. Special procedures are re­
quired for removal and installation
of this system. Therefore. any
work on the safety belt system
must be performed only by an au­
thorized Audi Dealer.
• The belt tensioner system
works for one accident only. If belt
tensioners have been activated.
the system must be replaced.
Notes
• When the safety belt tensioner is acti­
vated, a fine dust is released. This is normal
and is not caused by a fire in the vehicle.
• Observe all safety regulations if the ve­
hicle or individual parts of the system, par­
ticularly the safety belt or airbag, are to be
scrapped. Your authorized Audi Dealers are
familiar with these regulations and can per­
form this service for you.

---------------------------------------------------SAFETY RRST
Airbag system
Your vehicle has two front and four
side airbags, one front and one side air­
bag for each front seat occupant, one side
airbag" for each rear seat occupant sitting
on the left and right rear seat.
In addition, your vehicle is equipped with
head airbags* on the left and right sides to
protect occupants seated next to the front
and rear doors. System
components
The airbag system consists of the following:
• electronic control module,
• an inflatable airbag with gas generator in­
side the steering wheel,
• an inflatable airbag with gas generator in­
side the instrument panel tor the front pas­
senger,
• supplemental side airbags in the back­
rest padding of the front and rear seats*,
• an inflatable curtain head airbag above
the doors on each side,
• an AIRB AG indicator light in the
instrument cluster ( see "Warning I Indica­
tor lights" page 125).
The indicator light in the instrument cluster
(readiness light) will light up for a few sec­
onds each time the ignition is switched on.
The light monitors the electronic control
module, sensor circuits, and system wiring. The
system must be inspected
if the indicator light:
• does not come on when the ignition is
switched on,
• does not go out after a few seconds after
the ignition is switched on, or
• comes on while driving.
In the event of a system malfunction, the in­
dicator light will stay on continuously to
serve as a constant reminder to have the
system repaired.
�W ARNING
If any of these conditions occur,
have the alrbag system inspected
immediately by your Audi Dealer.
Otherwise, the airbags in your ve­
hicle may not work properly in
case of a frontal collision or a side
impact.

CONT
ROLS AND
EQUIPMENT---------------------
If the alarm has sounded one time, and then
the vehicle is forced open again (for exam­
ple, someone tries to forcibly open a door,
and then tries to force open the rear lid), the
signal will sound once again.
You can also trigger the alarm by pressing
the PANIC switch on your remote control
to alert other people in case of emergency
or when in another difficult situation. The
alarm can be switched off by pressing the
PA NIC switch again.
Warn ing lights
After you lock the vehicle, the warning light
on the window sills will blink quickly first for
30 seconds and will then blink slowly. This
is to let you know that the anti-theft alarm
system is activated, including the interior
move ment sensors.
If the warning lights come on continuously
for about 30 seconds instead of flashing
when the vehicle is locked, this indicates
that the interior movement sensor is defec­
tive.
68 Swit
ching off the interior
movement sensors l
Yo u should switch off the interior move­
ment sensors if there is the possibility that
the alarm system could be set off, for exam­
ple by a pet left in the vehicle. •
Press the switch in the door pillar (see il­
lustration). The indicator light in the switch
will come on. The indicator light on the win­
dow sills will come on for approx imately
3 seconds. This verifies that the interior
movement sensors have been deactivat ed.
The sensors will be reactivated when you
unlo ck and lock the vehicle again.
• Lock the vehicle.
The indi cator lights in the doorpillarwill blink
quickly for approximately 3 seconds at first.
Then, after approximately 30 seconds, the
light will flash slowly.

CONTROLS AND
EQUIPMENT--------------------
Acoustic park assist*
The acoustic parking warning system will
help make parking and maneuvering in tight
places easier for you. But since there are
technical limitations to what it can do, al­
ways exercise the utmost care and
attention when parking and when
maneuvering your vehicle in tight
places.
When you are backing up in parking maneu­
vers, a _ park assist warning system using ul­
trasonrc sensors helps you determine the
distance between your rear bumper, where
the sensors are located, and obstacles be­
hind the vehicle.
The parking assist system is activated as
soon as you put the vehicle in Re­
verse. A brief tone confirms that the sys­
tem is activated.
Distance warning in reverse begins at a dis­
tance of about 5.2 ft. (1.60 m) from the ob­
stacle. As the distance becomes smaller,
the time inteNal between the audible tones
grows shorter.
112 The
danger zone begins at a distance of
about 1 ft. (0.30 m). Do not back up any fur­
ther once you have reached the danger
z _one. The danger zone is signaled by a con­
trnuous tone.
�W ARNING
• The park assist system is not a
substitute for the driver's own
caution and alertness. Ultimate re­
sponsibility always lies with the
driver during parking and similar
maneuvers.
• Sensors have dead spaces in
which objects cannot be detected.
Be especially alert for small chil­
dren and animals, since they are
not always detected by the sen­
sors.
• Objects. such as trailer hitches,
thin painted rods, or fences, may
not always be detected by the sys­
tem, but they can damage your ve­
hicle. Note
• If a warning tone is audible for about 5
seco �ds when you turn on th e ignition, a
fault rs present in the system. Have the
problem corrected by your authorized Audi
dealer.
• The sensors must be kept clean and free
of ice for the park assist system to function
properly.

--------------------CONTROLS AND
EQUIPMEN T
When the red blinking symbols appear,
three warning tones will sound at the same
time. These symbols represent Danger.
• Do not continue to operate the
vehicle. The problem muat be lo­
cated and corrected immediately.
Pull off the road to a safe area, well away
from traffic, stop the engine and operate the
emergency flasher. Use other warning de­
vices to alert motorists. Contact your autho­
rized Audi Dealer or a qualified workshop.
In the event of multiple malfunctions, the
symbols will blink successively in two-sec­
ond interva ls. The symbols will continue to
blink until the malfunction is corrected.
Note If a malfunction is detected while you are
using the Navigation System, the Naviga­
tion System display will be switched off for
a few seconds and the Priority 1 Warning
symbol will appear. After that, the symbol
will change into the Priority 2 display, and
the Navigation System will be visible once
again.
As long there is a Priority 1 malfunction
present, Priority 2 malfunctions will not be
displayed. Ye

14 4 Speed
warning
You can store a road speed which is not to
be exceeded. As soon as you exceed that
speed by approximately 6 miles (1 0 kilome­
ters), a warning tone sounds and "MPH"
("k m/h ") appears in the disp lay.
Nota Always monitor the vehicle speed by
means of the speedometer. The speed
warning device may only be used as a re­
minder not to exceed the posted speed
limit. The
following describes how to store or de­
lete speed warnings 1 and 2.
Speed warning 1
The ''MPH" ("km/h ") disappears when you
reduce the speed below the stored speed.
Also, the ''MPH" goes out when the driving
speed increases approximately 25 mph
(40 km/h) over the set speed for at least
1 0 seconds. The stored speed is not de­
leted.
Selec ting speed limit
Press the test button for the Auto-Check
control briefly when the desired speed is in­
dicated on the speedometer. The speed
warning symbol lights up when the button
is released to confirm that the selected
speed has been stored.
The set speed limit remains stored until
another speed is selected by pressing the
button again or until the memory is cleared.

VE
HICL E OPERA TION-----------------------
'4 WARN ING continued
• Before descending a steep
grade, reduce speed and shift
transmission into a lower gear or
lower driving position. Do not ride
the brakes or hold the pedal down
too long or too often. This could
cause the brakes to get hot and di­
minish braking efficiency.
• If you damage the front spoiler,
or if you install a different spoiler,
be sure the air flow to the front
brakes is not obstructed. Other­
wise the brake system could over­
heat reducing the effective ness of
the entire brake system.
• Failure of one brake circuit will
impair the braking capability re­
sulting in an increased stopping
distance.
Avoid driving the vehicle and have
it towed to the nearest Audi Dealer
or qualified workshop.
204 Electronic differential lock
(EDL)
The EDL operates in conjunction with the
ABS. The EDL acts automatically, i.e. with­
out the driver's intervention.
With the aid of the ABS sensors, this sy­
stem monitors the speed of the driven
wheels up to about 50 mph, 80 km/h .
Within the speed range at which this sy­
stem operates, if the wheels spin (e.g. on
slippery surfaces) they are braked in a con­
trolled manner , and more of the engine's
power is directed to whiche ver wheels
achieve greater traction.
Please note:
• When driving off, always be sure to keep
road conditions in mind as you accelerate.
If a drive wheel spins because it's on a slip­
perier surface, gradually increase the pres­
sure on the accelerator pedal until the car
starts to move. •
When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the accelerator pedal.
Even with the EDL working, the drive
wheels can spin and reduce your ability to
control your car.
• To prevent the disc brake of the braked
wheel from overheating, if subjected to ex­
cessive loads the EDL cuts out temporarily.
The vehicle remains operational and be­
haves in the same way as a vehicle without
EDL
If a fault occurs in the ABS the EDL is also
not functioning. This is ind icated by the ABS
warning light-see page 125.
ftl WARNING
The increased safety afforded by
EDL does not mean that you can
take safety risks. Always adapt
your driving style to the road con­
ditions and traffic situation.

VEHICLE
OPER ATION----------------------
Operation
The Anti-Lock Brake System (ABS) and the
Electronic Differential Lock (EDU are inte­
grat _ed in the Electronic Stability Progr am. In
a _ddrtron to the data provided by these func­
tions, the ESP control unit requires addition­
al measurement data provided by hig h-per­
forman ?e sensors. The rotat ional speed of
the veh1cle about its vertical axis, vehicle lat­
eral acceleration, brake pressure and the
steering angle are measured.
The direction in which the driverwishes to
travel is determined with the aid of the
stee �ing angle and the vehicle speed and is
contmually compared with the actual be­
havior of the vehicle.
If the data do not match - for example when
a vehrcle is beginning to spin out of control
- the ESP applies the brakes to the appropri­
ate wheels for the given situation and, if
necessar y, changes the vehicle traction
forces so as to reduce the slipping of individ­
ual wheels (ASR anti-slip regulation).
206 The
vehicle is then stabilized by the forces
a ?tin � on the wheel during braking. If the ve­
hicle IS overstee ring (rear tends to skid out
of the turn), the brakes are mainly applied on
the wheel that is on the outside ofthe curve.
In the case of a vehicle that is und ersteering
(tendency to slide out of the curve). the
brakes are applied at the rear wheel that is
on the inside of the curve. An audible signal
�rll accompany the brake application func­
tion.
All �SP senso rs a�e monitored continuously
wh1le the vehicle IS being driven. However,
when the vehicle is driven at low speed on
ex tremely rugged terrain, it is not always
possrble to monrtor the ESP sensors contin­
uously. Thus, in rare and exceptional cases
the ESP itself can deactivate (ESP and ABS
ind icator lights will be lit continuously).
In this case. the ride level adjustment sys­
tem lowers the vehicle to the normal level
If this happens, you may need to select th�
ride level again (see page 153).
Operation of the ESP and ABS is restored
whenever you restart the engine. m
