Safety equipment
The safety features are part of the occupant
restraint system and work together to help
redu ce the risk of injury in a wide variety of
accident situations.
Your safety and the safety of your passenge rs
should not be left to chance. Advances in
technology have made a varie ty o f fea tures
avai la bl e to he lp re duce the risk of inj ury in an accident
. The following is a list of just a few of
the safety features in your Audi:
- sophis tic ated s afety be lts for d rive r and a ll
passenger sea ting pos it ions,
- be lt te nsione rs fo r th e fro nt sea ts a nd the
ou ter sea ting posit ions in the second row
seating,
- be lt h eight adjustment fo r th e front sea ts
an d the o ute r seat ing pos itions in the sec ­
ond row seating,
- he ad restra ints for e ach sea ting pos ition,

seating positions in the second row seat­ ing*,
- side curta in ai rbags,
- specia l LATCH anchorages for child re-
st raints,
- ad justab le steering colum n.
These individual safety features, can work to­ gether as a system to he lp protect you and
your passengers in a wide range of accidents .
These features cannot work as a system if
they are not always correctly adjusted and cor­ rectly used .
Safety is everybody's responsibil ity!
Important things to do before driving
Safety is everybody 's job! Vehicle and occu­
pant safety always depends on the informed
and careful driver.
For yo ur safety and the safety of your passen­
gers,
before driving always:
.. Make s ure that all lights and signa ls a re op ­
erati ng correctly .
.. Ma ke s ure that the tire pressure is correct .
.. Make s ure that all windows are clean and
afford good v is ibility to the o utside.
.. Secure a ll luggage a nd other items carefu lly
¢ page 87.
.. Make su re that nothing can in terfe re with
the peda ls.
.. Adjust fron t se at, head restraint and mir­
rors co rrec tly for you r heigh t.

.. Instruct passengers to adjust the head re ­
straints according to their height.
.. Make sure to use the right child restraint
correctly to protect children
c:> page 200,
Child Safety .
.. Sit properly in your seat and make sure that
your passenge rs do the same
c:> page 71,
General recommendations .
.,. Fasten your safety belt and wear it properly.
Also ins truc t your passengers to fasten their
safety belts properly
c:> page 170.
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 road
without being distracted.
The driver is respons ible for the safety of the
vehicle and a ll of its occupants . If your ability
to drive is impaired, safety risks for everybody
in the vehicle increase and you also become a
hazard to everyone else on the road
c:> .&,. .
Therefore:
.. Do not let yoursel f be distracted by passen­
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 cond it ions .
.. Take frequent breaks on long trips. Do not
drive for more than two hours at a stretch.
.. Do NOT drive when you are tired, under
pressure or when you are stressed .
A WARNING
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a veh icle is being used.
Driving Safely 161
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig. 182 Correct seat ing pos it 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
follow ing position:
.. Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floor
wh ile keeping your knee(s) slightly bent
c:> .&,. .
.. Adjust the angle of the seatback so that it is
in an upr ight position so that your back
comes in full contact w ith it when you drive .
.. Adjust the steering wheel so that there is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and yo ur breast
bone ~
fig. 182. If not possible, see your au­
thorized Audi dealer about adaptive equip­
ment .
.. Adjust the steer ing wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face.
.,. Grasp the top of the steer ing whee l with
your elbow(s) slightly bent.
.. Adjust the head restraint so the upper edge
is as even as possible with the top of your
head. If that is not poss ible, try to adjust
the head restraint so that it is as close to
this position as possible .
.. Fasten and wear safety belts correctly
c:>page 174.

to reduce the risk of injury when the vehi­
cle is not be ing used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open . A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out . Be ing trapped in a vehicle can
lead to serious persona l injury .
- Never let children play in or around the vehicle .
- Never let passe ngers r ide in the luggage
compartment . Ve hicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air c irculation helps to reduce window
fogging . Sta le air escapes to the outside
th rough vents in the trim pane l. Be su re
to keep these slots free and open .
-The t ire pressure must correspond to the
load. The t ire pressur e is shown o n the
tire p ress ure label. The tire pressure la­
bel is loc ated on the d river's s ide B-pi ll a r.
The t ire pressure label lists the recom­
mended cold ti re inflat ion pressu res for
the vehicle at its maximum capacity
weig ht and the tires that were on you r
vehicle at the time it was man ufactured .
For recommended t ire pressures fo r nor­
mal load conditions, please see chap ter
c:> page278 .
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items .
Use the tie-downs to secure your cargo prop­
erly
c:> page 166, Loading the luggage com ­
partment.
In a coll is ion, the l aws of phys ics mean that
even smalle r items that are loose in the vehi­
cle will become heavy missiles that can cause
Dr iving S afel y 167
serious injury. Items in the ve hicle possess en ­
ergy which vary with vehicle speed and th e
weight o f the item . Vehicle speed is the most
s ignificant factor.
Fo r example, in a fronta l collision at a speed
of 30 mph (48 km/h), the forces acting on a
10 -lb (4.5 kg) object are about 20 t imes the
no rmal weight of the item. This means t hat
the weigh t of the item would sudden ly be
about 200 lbs. (90 kg) . You can imag ine the
i njur ies that a 200 lbs . (90 kg) item fly ing
fr eely th ro ugh the passenger compar tme nt
c ould cause in a co lli sion like this.
A WARNING
We ak, dam aged or imprope r str aps used
to secure items to tie -downs can fail dur­
ing hard braking or in a collision and cause
serio us personal injury .
-Always use s uita ble mount ing stra ps and
properly secu re items to the tie-downs in
the l uggage compa rtme nt to he lp pre­
vent items from shift ing or f ly ing fo r­
ward as dangerous missiles .
-When the rea r seat backrest is folded
down, a lways use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to hel p prevent items from fly ing for­
ward as da ngerous missiles into the pas­
s enger compartment .
- Never attach a chi ld safety seat te th er
s trap to a t ie- down .

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. EDRs are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs 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 example, 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.
Intelligent technology 219
Electronic Stability
Control (ESC)
General information
The ESC improves the vehicle stability.
. ..---------..
------- -
Fig. 218 Center console with ESC sw itch
ESC is designed to help you maintain vehicle
control in situations where the car approaches
the limits of "grip", especially when accelerat­
ing and cornering. ESC reduces the risk of
skidding and improves stability under all road
condit ions .
The system operates across the entire speed range in combination with the ABS system. If
the Anti-Lock Brake System (ABS) malfunc­
tions, the ESC will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic
Differential Lock (EDL) and the Anti-Slip Regu­
lation System (ASR) are integrated in the Elec­
tronic Stability Control. In addition to the da­
ta provided by these functions, the ESC con­
trol unit requires additional measurement da­
ta provided by high performance sensors. The
rotational speed of the vehicle about its verti­
cal axis, vehicle acceleration in the fore-and­
aft and lateral directions, the brake pressure and the steering angle are all measured.
T he direction in wh ich the driver wishes to
travel is determined with the aid of the steer­
ing angle and vehicle speed and is continually
compared with the actua l behavior of the ve­
hicle. If the two do not match, for example,
when the vehicle starts hydroplaning on a wet
road, ESC will automatically brake the appro-
priate wheel to correct the problem. ..,_

-Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and dimin ish braking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not intend
to bra ke. Th is may cause the brakes to
overheat, prema ture wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, 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, linings,
discs and drums. Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct ­
ed. Otherwise the brake system co uld
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est author ized Audi dealer or qualified
workshop .
Brake booster
The brake booster adds extra braking power.
The brake booster works with vacuum pres­
sure which is created only when the engine is
running¢ &,.
Int ellig ent technolog y 223
A WARNING
-Never let the veh icle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
example when towing your vehicle, or because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the la ck of booster assistance .
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­
der braking.
T he ABS contributes effect ively to vehicle con­
trol s ince it preve nts the whee ls from
locking
when the brakes are applied. This means that
the vehicle remains steerable and is less likely
to skid .
With ABS y ou do not nee d to pump the
bra ke. Just h old t he br ake ped al d own .
However, do not expect the ABS to shorten
braking distance under
all circumstances.
When dr iving on g ravel or on new ly fallen
snow o n top of icy s urfaces, braking dis tance
may be even longer, therefore, under these
circumstances, it is especia lly important that
you drive s low ly and wit h great care.
How the ABS s ystem works
An a utomat ic check is made when a speed of
about 12 mph (20 km/h) is reached . When
th is happens, a pumping noise can be heard.
If an ind iv idual whee l begi ns to rotate too
s low ly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent tha t whee l from locking .
T his automatic adjustment p rocess will cause
a
sli ght vibrati on of the brake pedal and some
no ises to a le rt you that ve hicle speed m ust be
adapted to existing road and traffic condi ­

vehicle to the cold ti re pressu re listed under
" F u ll load" on the tire pressure label. The tire
pressure label is located on the drive r's side B­

nected from the trai le r to the hitch on the ve­
hicle. Leave enough slack in the ch ains to pe r­
mit turning corners. When you install safety
chains, make sure they will not drag on the
road when you are driving. ..,.
