The
higher the speed of the vehicle and the
greater the passengers' weight, the more
energy there is to be "absorbed" in an acci­
dent.
Vehicle speed is the most significant factor.
If the speed doubles from 15 to 30 mph (25
to 50 km/hl. the energy increases 4 times!
Because these passengers are not using
safety belts, they will keep moving at the
same speed the vehicle was moving just
before the crash, until something stops
them -here, the wall. The same
principles apply to people sitting
in a car that is involved in a frontal collision.
Even at city speeds of 20 to 30 mph (30 to
50 km/h), the forces acting on the body can
reach one ton (2000 lbs, or 1 000 kg) or
more. At greater speeds, these forces are
even higher.
People who do not use safety belts are also
not attached to their car. In a frontal collision
they will also continue to move forward at
the speed their car was travelling just be­
fore the impact. SA
FETY FIRST
Un belted occupants are not able to resist
the tremendous forces of impact by holding
tight or bracing themselves. Without the
benefit of safety restraint systems, the un­
restra ined occupant will slam violently into
the steering wheel, dashboard, windshield,
or whatever else is in the way. Their impact
with the vehicle interior has all the energy
they had just before the crash.
15

SA
FETY FIRST
Don't rely on airbags alone for protection.
Even when they deploy, airbags provide
only supplemental protection. Airbags are
not supposed to deploy in all kinds of acci­
dents. Although your Audi is equipped with
airbags for the driver and front seat passen­
ger, all vehicle occupants, including the
driver, still have to wear safety belts- re­
gardless of whether their seating position
has an airbag.
Remember too, that airbags will deploy only
once and that your safety belts are always
there to offer protection in those accidents
in which airbags are not supposed to deploy
or when they have already deployed.
Unbelted occupants can also be thrown out
of the car where even more severe or fatal
injuries can occur.
16 Unbelted
passengers in the rear seats en­
danger not only themselves but also other
passengers. In a frontal collision they will be
thrown forward violently, where they can hit
and injure the driver or front seat passenger.
Safety belts protect
Safety belts used properly can make a big
difference. Safety belts help to keep pas­
sengers in their seats, gradually reduce en­
ergy levels applied to the body in an acci­
dent, and help prevent the uncontrolled
movement that can cause serious injuries.
In addition, safety belts reduce the danger
of being thrown out of the car. Safety
belts attach passengers to the car
and give them the benefit of being slowed
down more gently or "softly" through the
"give" in the safety belts, crumple zones
and other safety features engineered into
today's cars. By "absorbing" the kinetic en­
ergy over a longer period of time, the forces
on the body become more "tolerable" and
less likely to cause injury.

FETY RRST-----------------------------------------------------
�WARNING continued
• Do not cover, obstruct, or
change the steering wheel horn
pad or airbag cover or the instru­
ment panel, particularly in the area
of the passenger side airbag mod­
ule.
• For cleaning the horn pad or in­
strument panel, use only a soft,
dry cloth or one moistened with
plain water. Solvents or cleaners
could damage the airbag cover. Do
not make any repairs, adjust­
ments, or modifications to any
parts of the airbag system.
• Do not modify the front bumper
or vehicle body structure.
42 ftl
WARNING continued
• Never place protective seat cov­
ers or replacement upholstery
over the front and rear seatbacks
that have not been specifically ap­
proved by Audi. Since the side air­
bags deploy out of the side of the
seatback, it would not be able to
deploy and protect properly.
• Do not use additional seat cush­
ions that cover or interfere with
the areas where the side airbags
inflate.
• Damage to the original seat cov­
ers or to the seam in the area of the
side airbag module must be re­
paired immediately by an autho­
rized Audi Dealer.
• The airbag system must be re­
placed by your authorized Audi
Dealer no later than 14 years after
the manu facture date of your ve­
hicle. �,
WARNING continued
• The manufacture date can be
found on the Safety Compliance
Sticker located on the left door
jamb as well as on the Vehicle
Identification Label in your
Maintenance booklet. It is abso­
lutely essential to observe this
date in order to assure that the sy­
stem is in good working order.
• If components of the airbag sys­
tem must be discarded, or ifthe ve­
hicle must be scrapped, certain
safety precautions must be ob­
served. Your authorized Audi
Dealer knows these precautions
and can give you the necessary in­
forma tion. Failure to follow these
precautions and procedures could
increase the risk of personal in­
jury.

-------------------------------------------------SAFETY ARST
In a collision, airbags must inflate within a
blink of an eye and with considerable force.
In order to do its job, the airbag needs room
to inflate so that it will be there to protect
the occupant as the occupant moves for­
ward into the airbag.
A vehicle occupant who is out of position
and to close to the airbag gets in the way of
on infloting nirbag. When an occupant is too close he or she will be stru ck violently and
will r� ceive serious or possibly even fatal in­
jury.
In order for the airbag to offer protection, it
is important that all vehicle occupants, es­
pecially children who must ride on the front
seat in excep tional situations, be properly
restra ined and as far away from the airbag
as possible. By keeping room between your
body and the front of the passenger
compartment, the airbag can inflate fully
and completely and provide supplemental
pro tection in certain frontal collisions. �W
ARNING
Never let a child stand or kneel on
any seat, particularly the front
seat. Never let a child ride in the
cargo area of your car. If a child is
leaning forward, sitting sideways
or out of position in any way, the
child is more likely to be injured in
a crash and will receive serious or
fatal injuries if the child comes
into contact with an airbag as it in­
flates.
Safety belts and older children
Children of average size of about 7 years of
age and older may use the lap belt in excep­
tional circumstances if the proper use of
three point belts is not possible. Always re­
member that children do not have the pro­
nounced pelvic structure required for the
proper function of lap belts. The child's
safety absolutely requires that a lap belt be
fastened snugly and as low as possible
around the pelvis. Never let a lap belt pass
over the child's stomach or abdomen.

CONTROLS AND
EQUIPMEN T--------------------
If the warning light is flashing, it can also
mean that the vehicle is riding ''too high"
(above the highest level). Once again, do
not drive off until the warning light stops
flashing.
If the .warning light stays on continuous ly,
there 1s a problem with the ride height ad­
JUStment system. The light will also come
on continuously if the vehicle is on an ex­
treme incline.
Tro uble in the ESP may also cause the warn­
ing light to remain on continuously.
A system failure can cause the vehicle to
have too little or too much ground clear­
ance. Drive very carefully and slowly to your
nearest authorized Audi dealer and have the
fault corrected.
See page 153 for additional information.
12 4 Electronic Stability
Program {ESP)
The indicator light lights up when the igni­
tion is turned on, and it must go out after
about 2 seconds.
When the ESP system is in control mode,
this indicator light will flash while the ve­
hicle is being operated.
When you start the engine, the ESP
may shut off for safety reasons. The indica­
tor light also turns on to indicate this statu s.
If this should happen, you can reactivate the
ESP by turning the ignition off and then on
� gain. This indicator light will go out, indicat­
Ing that the system is once again operating
properly.
If the system is off or is malfunctioning, the
indi cator light will remain on.
Since the ESP system works together with
the ABS system, the ESP indicator light will
also come on if the ABS stops operating. Electronic
immobilizer
�
When you turn on the ignition, the vehicle
key data are automatically scanned. The in­
dicator light will come on briefly, indicating
that the data verification procedure has
been acknowledged.
If a non-coded vehicle key was used (for ex­
ample a duplic ate key), the control light
goes to a continuous flashing mode. If this
happens, the vehicle cannot be started. See
also page 57

Turn signals and
emergency flasher
Refer to "Turn signal I headlight d1mmer
switch lever and emergency flasher" on
pages 152 and 156 for details.
High beam �D
The indicator light lights up when the high
beams are switched on or when the head­
light flasher is used.
See "Turn signal I headlight dimmer switch
lever" on page 156 for details.
Malfunction Indicator
�
Lamp (MIL) CHECK
The Malfunction Indicator Lamp is part of
the On Board Diagnostic system (OBD).
The lamp comes on when the ignition is
switched on and will go out after the engine
is started and the idle has stabilized. This is
to assure you that the Malfunction Indicator
Lamp is working properly.
For more details, see page 128. Airbag
System AIR
BAG
The ind icator light for the airbag and belt
tensioner system must come on when
the ignition is switched on, and go out after
a few seconds. If the light does not go out,
or if it comes on while you are driving, this
ind icates a fault in the airbag I belt tensioner
syste m.
If the indicator light does not come on when
the ignition is switched on, this also indi­
cates a system malfunction. If any of these
conditions occur, have the air bag system in­
spected immediately by your authorized
Audi Dealer.

This warn ing light monitors the ABS and
EDL (Electronic Differential Lock,
sys tems.
The light will come on for a few seconds
when the ignition is switched on. The light
will go out after an automatic check se­
quence.
For additional information on the ABS sy­
stem, see page 202.
� WARNING
If the ABS warning light does not
go out, or if it comes on while driv­
ing, the ABS system is not working
properly. The vehicle can then be
stopped only with the standard
brakes (without ABS,. You won't
have the protection ABS provides.
Contact your Audi Dealer as soon
as possible.

CONTROLS
AND EQUIPMENT---------------------
If there is an ABS problem:
o The ABS warning light to come
on. The vehicle can still be braked,
however, the ABS will not work. See
your authorized Audl Dealer as soon
as possible.
• The ABS warning light and the
brake warning light come on to­
gether. The ABS will not work and
you will notice a change in braking
characteristics and performance.
�W ARNING
If both warning lights (ABS and
BRAKE warning light) come on at
the same time, the rear wheels
could lock up first under hard
braking. Rear wheel brake lock-up
can cause loss of vehicle control
and an accident. Have your vehicle
repaired immediately by your au­
thorized Audi Dealer or a qualified
workshop. Drive slowly and avoid
sudden, hard brake application.
12 6 If
the ABS fails, the ESP warning light will
come on. See page and pages 202 -205.
Electronic differential lock (EDL)
The electronic differential lock works in con­
junction with the ABS system. A fault in the
ABS causes therefore a malfunction of the
electr onic differential lock.
For more details on how the EDL works, go
to page 204.
Brake
USA models:
BRAKE
Canada models:
(Q))
The light comes on while the engine is
cranking. It goes out after the engine has
been started and the parking brake is fully
released. This is your assurance that the
brake warning light is functioning properly. A If the brake warning light does ¥ not light up when the engine is
cra nking or the parking brake is ap­
plied, there may be a malfunction in
the electrical system. In this case,
contact your Audi Dealer.
When the light comes on, an audible warn­
ing signal is also given.
�W ARNING
• If both warning lights (ABS and
BRAKE warning light) come on at
the same time, the rear wheels
could lock up first under hard
braking. Rear wheel brake lock-up
can cause loss of vehicle control
and an accident. Have your vehicle
repaired immediately by your au­
thorized Audi Dealer or a qualified
workshop. Drive slowly and avoid
sudden, hard brake application.

VE
HICL E OPER ATION------------------------
Functioning of Anti-Lock Brake
System (ABS)
The ABS contributes effectively to vehicle
control since it prevents the wheels from
locking when the brakes are applied. This
means that the vehicle remains steerable
and is less likely to skid.
Nota
Yo u don't have to "pump" the brake.
Just hold the brake pedal down.
However, do not expect that the ABS short­
ens braking distance under all circum­
stances. When driving on gravel or on newly
fallen snow on top of icy surfaces, braking
distance may be even longer , therefore, un­
der these circumstances, it is especially im­
portant that you drive slowly and with great
care.
202 How the
ABS system works
An automatic check is made when a speed
of about 4 mph (6 km/h) is reached.
When this happens a pumping noise can be
heard.
If an individual wheel begins to rotate too
slowly in relation to vehicle speed and tends
to lock, the ABS automatically reduces
brake pressure to prevent that wheel from
locking.
This automatic adjustment process
will cause a slight vibration of the
brake pedal and soma noises to alert
you that vehicle speed must be
adapted to existing road and traffic
conditions. Enhanced
ABS function {Offroad­
Mode)
To improve braking on loose terrain (for ex­
ample: gravel, scree, mud, slush, snow),
turn off the ESP (see page 205), which will
switch the ABS to a special mode designed
for off-road requirements.
In this mode, the ABS control system is
changed to allow a "wedge" of loose rock
or soil to form in the front of the wheels.
This improves braking performance.
The ESP indicator light in the instrument
cluster will come on when you have
switched to this special ABS mode (see
page 124).
This special ABS mode will remain active up
to about 40 mph (60 km/h). ABS operation
is not affected at speeds over 40 mph
(60 km/h).
To turn his special ABS mode off, press the
ESP button (To activate ESP, see page 152).
The ABS off-road mode will also be deacti­
vated when vou turn off the engine.

�W
ARNING
Although the ABS is very effec­
tive, always remember that brak­
ing capability is lim ited by tire
tracti on.
Always adjust your driving speed
accor ding to the road and traffic
conditions. Do not let the extra
safety afforded by the ABS tempt
you into taking extra risks. The
ABS cannot overcome the laws of
physics.
If ABS is not functioning properly, a warning
light will come on. See page 125 for addi­
tional details. Conditions
affecting
braking efficiency
Moisture or road salt
�W ARNING
• Under certain climatic and oper­
ating conditions such as passing
through water, driving in heavy
rain or after washing the vehicle,
the effectiveness of the brakes
can be reduced. In winter, ice can
accumulate on the brake pads, lin­
ings, discs and drums. Cautiously
apply brakes for a test. Brakes will
dry and ice coatings will be
cleaned off after a few cautious
brake applications. VE
HICLE OPERATION
� WARNING continued
• Driving for an extended period
of time on salt-covered roads with­
out using your brakes can also af­
fect braking efficiency. Clean off
accumulated salt coating from
brake discs and pads with a few
cautious brake applications.
Overhea ting the brakes
�W ARNIN G
• Do not "ride the brakes" by rest­
ing your foot on the pedal when
you do not intend to brake. This
may cause the brakes to overheat,
premature wear and Increased
stopping distance.
Always heed all WAR NINGS
on next page.
