faster than 85 mph (140 km/h). Drive immedi-
ately to an authorized Audi dealer or authorized
Audi Service Facility to have the malfunction re-
paired. The color of the indicator light depends
on the vehicle speed.

ZA WARNING
Driving at higher speeds without the rear
spoiler deployed can impair handling charac-
teristics, making the vehicle harder to control.
— Always make sure that the spoiler is de-
ployed when driving at speeds over 85 mph
(140 km/h). If the rear spoiler warning/indi-
cator light in the instrument cluster comes
on, the rear spoiler may not have deployed.
— Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed.
Have the spoiler inspected as soon as possi-
ble by an authorized Audi dealer or qualified
workshop.
— Always obey speed limits and other traffic
laws.
— Hot air from the engine compartment can
escape through the rear spoiler when it is
open and it could burn you.

ZA\ WARNING
Improper operation of the rear spoiler can
cause crushing injuries.
— Always make sure that nobody, especially
children, is in the way when the rear spoiler
is deployed or retracted.

©) Note
— Never push on the vehicle on the rear spoil-
er. This could cause damage.
— To prevent damage to the rear spoiler do
not lean or place anything on it.
—To reduce the risk of damage, only operate
the rear spoiler manually when the engine
compartment lid is closed and the moving
parts for the rear spoiler are not blocked.
G@) Tips
Clean the rear spoiler compartment every 2 to
3 months. To function correctly, the rear
spoiler must be free of ice, snow and leaves.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
(i) Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will 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 limited or
switched off.
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re-
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an airbag deployment or hitting a
road obstacle, data that will assist in understand-
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy-
namics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
— How various systems in your vehicle were oper-
ating;
— Whether or not the driver and passenger safety
belts were buckled/fastened;
— How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
— How fast the vehicle was traveling.
These data can help provide a better understand-
ing of the circumstances in which crashes and

Safe driving

> Never allow anyone to assume an incorrect
seating position when the vehicle is being used
>/\.
The following bulletins list only some sample po-
sitions that will increase the risk of serious injury
and death. Our hope is that these examples will
make you more aware of seating positions that
are dangerous.
Therefore, whenever the vehicle is moving:
— never stand up in the vehicle
— never stand on the seats
— never kneel on the seats
— never ride with the seatback reclined
— never lie down on the seats
— never lean up against the instrument panel
— never sit on the edge of the seat
— never sit sideways
— never lean out the window
— never put your feet out the window
— never put your feet on the instrument panel
— never rest your feet on the seat cushion or back
of the seat
— never ride in the footwell
— never ride in the cargo area

ZA\ WARNING
Improper seating positions increase the risk
of serious personal injury and death whenever
a vehicle is being used.
— Always make sure that all vehicle occupants
stay in a proper seating position and are
properly restrained whenever the vehicle is
being used.


Driver and passenger
side footwell

ZA\ WARNING
Always make sure that the knee airbag can in-
flate without interference. Objects between
yourself and the airbag can increase the risk
of injury in an accident by interfering with the



176

way the airbag deploys or by being pushed in-
to you as the airbag deploys.
— No persons (children) or animals should ride
in the footwell in front of the passenger
seat. If the airbag deploys, this can result in
serious or fatal injuries.
— No objects of any kind should be carried in
the footwell area in front of the driver's or
passenger's seat. Bulky objects (shopping
bags, for example) can hamper or prevent
proper deployment of the airbag. Small ob-
jects can be thrown through the vehicle if
the airbag deploys and injure you or your
passengers.

Pedal area
The pedals must always be free to move and
must never be interfered with by a floor mat or
any other object.
Make sure that all pedals move freely without in-
terference and that nothing prevents them from
returning to their original positions.
Only use floor mats that leave the pedal area free
and can be secured with floor mat fasteners.
If a brake circuit fails, increased brake pedal trav-
el is required to bring the vehicle to a full stop.

ZA\ WARNING
Pedals that cannot move freely can cause loss
of vehicle control and increase the risk of seri-
ous injury.
— Never place any objects in the driver's foot-
well. An object could get into the pedal area
and interfere with pedal function. In case of
sudden braking or an accident, you would
not be able to brake or accelerate!
— Always make sure that nothing can fall or
move into the driver's footwell.

Always use floor mats that can be securely at-
tached to the floor mat fasteners and do not in-
terfere with the free movement of the pedals.
> Make sure that the floor mats are properly se-
cured and cannot move and interfere with the
pedals > A\.
Use only floor mats that leave the pedal area un-
obstructed and that are firmly secured so that
they cannot slip out of position. You can obtain
suitable floor mats from your authorized Audi
Dealer.
Floor mat fasteners are installed in your Audi.
Floor
mats used in your vehicle must be attached
to these fasteners. Properly securing the floor
mats will prevent them from sliding into posi-
tions that could interfere with the pedals or im-
pair safe operation of your vehicle in other ways.

ZA\ WARNING
Pedals that cannot move freely can result ina
loss of vehicle control and increase the risk of
serious personal injury.
— Always make sure that floor mats are prop-
erly secured.
— Never place or install floor mats or other
floor coverings in the vehicle that cannot be
properly secured in place to prevent them
from slipping and interfering with the ped-
als or the ability to control the vehicle.
— Never place or install floor mats or other
floor coverings on top of already installed
floor mats. Additional floor mats and other
coverings will reduce the size of the pedal
area and interfere with the pedals.
— Always properly reinstall and secure floor
mats that have been taken out for cleaning.
— Always make sure that objects cannot fall in-
to the driver footwell while the vehicle is
moving. Objects can become trapped under
the brake pedal and accelerator pedal caus-
ing a loss of vehicle control.

while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“p” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
