standard brakes (without ABS). You w ill
not have the protect ion ABS provides.
Contact your Audi dea le r as soon as pos­
sible.
- USA models: If the . warning light, the
G1 warning light and the 1111 warning
light come on together, the rear wheels
could lock up fi rst under hard braking .
Rear wheel lock -up can cause loss o f ve ­
hicle control and an accident. Have your
vehicle repaired immediately by your au­
thorized Audi dealer or a qualified work­
shop. Drive s low ly and avoid sudden,
hard brake applications. ..,.

light does not appear and stay on have
the a irbag system inspected by your Audi
dealer.
- A tight tether or other strap on a rear­
ward-fac ing child restra int attached to
the front passenger seat can put too much pressure on the weight-sens ing
mat in the seat and register more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adu lt were on the seat
and deploy the Advanced Airbag when it
must be suppressed caus ing serious or
even fatal injury to the child .
- If, in exceptional circ umstances, you
must install a forward-facing child re­
st raint on the front passenger seat, a l­
ways move the seat into its rearmost po­
sit ion in the seat's fo re and aft adjust­
ment range, as far away from the airb ag
as possib le . The backrest m ust be adjust­
ed to an upright position. Make sure that
the

ever the ignition is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, have the air­
bag system inspected by your Aud i deal­
er before transporting anyone on the
front passenger seat.
(Di Tips
If the weight-sensing mat in the front pas­
senger seat detects an empty seat, the

Repair, care and disposal of the airbags
Parts of the airbag system are i nstalled at
many diffe rent p laces o n your Aud i. Insta llin g,
removing, servicing or repa iring a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a coll is ion.
T he re a re some important t hings you have to
know to make sure that the effectiveness o f
the system wi ll not be impaired and that dis­
carded components do not cause injury or pol ­
lute the environment.
A WARNING
Improper care, serv ic ing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an a irbag
from deploying when needed or deploying
an a irbag unexpec tedly:
- Never cover, obst ruct, or change the
steer ing whee l horn pad or airbag cover
or the inst rument panel or mod ify them
in any w ay .
- Never attach any objects s uch as c up
holders or telephone mountings to the
surfaces covering the a irbag un its .
- For cleaning the horn pad or instr ument
panel, use only a soft, dry cloth or one
mo istened with pla in water. Solvents or
cleaners could damage the airbag cover
or change the st iffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the a irbag system.
- All work on the steering wheel, instru­
ment panel, front seats or e lectr ica l sys­
tem (including the installation of audio
equ ipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technic ian who has the training
and specia l equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
author ized Audi dealer or qualified work-
shop.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 141
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
B.J in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface. If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficu lt driving situations as at lower
speeds.
Always adjust your speed and driving style to
road, traffic §&and weather conditions. ESC
cannot override the vehicle's physical limits,
increase the available traction, or keep a vehi­
cle on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by usin g the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti- lock brake system (ABS), brake assist sys -
tem and anti-slip regu lation (ASR). ESC is
Ill>

142 Intelligent technology
switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
l!l . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -toc k brak ing system (ABS)
ABS prevents the wheels from lock ing up
when braking . The vehicle can still be steered
even during hard brak ing . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal ind icates that
the system is he lp ing you to brake the vehicle .
Brake assist sy stem
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presse s the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake peda l until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to the road conditions . This makes it easier to
start, accelerate and drive up hills.
E lectronic differential lock (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL a utomatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL will switch on aga in au­
tomatically when conditions have returned to normal.
A WARNING
- ESC, ABS, ASR and ED L can not ove rcome
t h e laws of phy sics. This is espe cial ly im ­
por tant on slip pery or wet ro ads .
If th e
sys tems begin a ct in g to stab ilize your ve­
hicle, you shou ld imme diately change
yo ur speed to match the road and traffic
condit ions. Do not let the inc reased safe­
ty provided by these systems tempt you to take risks. Do
ing so w ill increase the
risk of a loss of veh icle control, co llision
and serious pe rsonal injuries .
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of t he vehicle increases when
driving too fast, espec ially through
curves and on slippe ry or wet roads, and
wh en dr iv ing too clos e to vehicl es u p
ahead. ESC, A BS, the brake ass ist sys­
tem, ED L and ASR cannot p reven t coll i­
si ons .
- Always acceler ate wi th sp ecial c are on
even, smoo th s urfaces such as those th at
are wet or covered with ice and snow .
The drive wheels can spin even with
these assistance systems that cannot al­ ways he lp to reduce the risk of loss of ve­
h icle co ntrol.
(D Tips
- ABS an d ASR only wo rk correct ly when
all four whee ls are equipped with identi­
cal tires . D ifferent tire si zes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator light Ii) or II (USA
mode ls)/ Ei] (Canada models) appears,
there may be a malfunction

-If the tire pressure is too low or too high,
the tires w ill wear prematurely and the
vehicle will not handle well.
- If the t ire is not flat and you do not have
to change a wheel immed iately, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Dr iving without va lve stem caps can cause
damage to the t ire va lves. To prevent this ,
always make sure that facto ry installed

Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can c arry.
A vehicle that is overloaded w ill not h andle
well and is more difficult to s top. Over load ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
ve hicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the veh icle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and eve ryth ing in and on the vehicle . These
