Head restraints
Front head restraints
Fig. 81 Fro nt seats head rest ra in ts: adjust ing the
height
The head restraints on the front seats can be
adjusted to provide safe support to head and
neck at the optimum height. When optimally
adjusted, the top of the restraint should be level with the top of the head . If that is not
possible, try to adjust the head restraint so
that it is as close to this position as possible
¢ page 167 , Proper adjustment of head re­
straints .
~ To move the head restraint up, hold it at the
sides with both hands and slide it upward.
~ To move the head restraint down, press the
button and slide the head restraint down­

head restraints
for guidelines on how to ad­
just the height of the front head restraints to
su it the occupant's body size.
A WARNING
- Driving without head restraints or with
head restraints that are not properly ad­
justed increases the risk of serious or fa­
tal neck injury dramatica lly.

110 On the road
The parking brake warning light. (USA)/ .
(CON) illuminates when the parking brake is
set and you switch on the ignition.
A WARNING
-
Always release the parking brake com­
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef­
fectiveness and cause excessive wear. This could lead to brake failure and an accident .
(D Note
Only after the vehicle has come to com­
plete stop, should you firmly set the park­
ing brake and
move the selector lever into
P.
Parking
• Press the brake pedal to stop the vehicle .
• Apply the parking brake firmly
r=,> page 109,
fig. 123 @.
• Move the selector lever to P.
.. Turn the engine off~_& .
.. When on inclines or declines, turn the steer­
ing wheel so that the vehicle will roll into
the curb if it begins to
move.
A WARNING
This is how you can reduce the risk of in­
jury when leaving your vehicle.
- Never park the vehicle where it can come
in contact with dry grass, spilled fuel or
any other flammable materials.
- When parking on hills, always turn the
wheels so that the front wheels will first
roll into the curb, if the vehicle should
start to roll.
- Never allow anyone - especially small
children - to remain in the vehicle when
it is locked. Locked doors make it more
difficult for rescuers to access the pas­
senger compartment in the event of an
emergency. Danger to life!
- Never leave children unsupervised in the
vehicle. Children could release the park­
ing brake or
move the gearshift lever out
-
of gear. The vehicle could start to roll
away and cause an accident.
- No matter what the season is, the tem­
perature in a parked vehicle can reach
dangerous levels.
Q) Note
- Please exercise care when you park your
vehicle in parking areas with parking bar­
riers or curbs. Parking barriers and curbs
vary in height and could damage your
bumper and related components as the
front of your vehicle
moves over a barrier
or curb that is too high, as you park or as
you back out of a parking spot. In order
to be sure that no such damage can oc­
cur, you may wish to stop short of having
the front tires of your car touch the park­
ing barrier or curb.
- Please also exercise exceptional care
when you drive up or down steep ramps
or drive
over curbs or other obstacles, for
which the vehicle is not designed, be­
cause components of th@ vehicle close to
the ground, such as bumper covers,
spoilers and suspension and exhaust sys­
tem components, may become dam­
aged.
Starting on hills
Hill Hold makes it easier to start on hills.
The system is activated when the brake pedal
is depressed
for a few seconds . For this, the
vehicle must be standing in uphill driving di­ rection.
After releasing the brake pedal, the brake power is held for a
brief moment to prevent
the vehicle from rolling back when starting. At
this time, you can easily begin to
move your
vehicle.
A WARNING
- If you did not begin moving immediately
after releasing the brake pedal, under
certain circumstances, the vehicle would
begin to roll backward. Depress the ..,.

176 Safety belts
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 199 A driver not wearing a safety belt is violently
thrown forward
Fig. 200 A rear passenger not wearing a safety belt
will fly forward and strike the drive r
Unbelted 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 unrestrained oc­
cupant will slam violently into the steering
wheel, instrument panel, windshield, or what­
ever else is in the way
q fig. 199. This impact
with the vehicle interior has all the energy
they had just before the crash.
Never rely on airbags alone for protection.
Even when they deploy, airbags provide only
additional protection. Airbags are not sup­ posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver, must
wear safety belts correctly in order to mini­
mize the risk of severe injury or death in a
crash.
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 vehi­
cle where even more severe or fatal injuries
can occur .
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passen­
gers in the rear seats endanger not only them­
selves but also the driver and other passen­ gers¢
fig. 200. In a frontal collision they will
be thrown forward violently, where they can
hit and injure the driver and/or front seat pas­
senger.
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision. It's simply
not true!
Fig. 201 Driver is correctly restrained in a sudden brak­
ing maneuver
Safety belts used properly can make a big dif­
ference. Safety belts help to keep passengers
in their seats, gradually reduce energy levels
applied to the body in an accident, and help
prevent the uncontrolled movement that can
cause serious injuries. In addition, safety belts
reduce the danger of being thrown out of the
vehicle.
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, crush zones and other safety
features engineered into today's vehicles. By
"absorbing" the kinetic energy over a longer
period of ti me, the safety belts make the

conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U.S. Federal Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de­
ployment are met.
-Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide additional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over­
all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you, if you are sitting up­
right , wearing your safety belt and wearing it
properly. This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to meet the "low risk" re­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side. The low risk deployment crite­
ria are intended to help reduce the risk of in- jury through interaction with the front airbag
that can occur, for example, by being too close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the Standard
~ page 206, Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re­
strained on the front passenger seat in one
of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your vehicle was
certified. For a listing of the child restraints
that were used to certify your vehicle's com­
pliance with the US Safety Standard
~page 206,
-weight less than a threshold level stored in
the control unit is detected on the front pas­
senger seat.
When a person is detected on the front pas­ senger seat, weighing more than the total
weight of a child that is about 1 year old re­
strained in one of the rear-facing or forward­
facing infant restraints (listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen­ ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­ quires the front airbag to be turned off. If the
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger
side has not been turned off by the control
unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory.

198 Airbag system
@ For the sake of the environment
Undep loyed airbag modu les and preten­
sioners might be classified as Perchlorate Material -special handling may app ly, see
www.dtsc.ca.gov/haza rdouswaste/per­ chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts w ith pretens ioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authori zed
Audi dea ler is familiar with these requ ire­
ments and we recommend that you have
your dea ler perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-r im combinations not approved by Aud i,
l owering the vehicle, changing the stiffness o f
the suspension, including the springs, s uspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam­
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in wh ich it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas ­
u red by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
driver and front passenger sea t tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen- sors can send the correct info
rmation about
safety belt use to the electronic control unit.
.&_ WARNING
-
Changing the vehicle's suspension includ- ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
&_ WARNING
--
Items stored between the safety be lt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the e lectronic con­
trol module and prevent the Advanced Air ­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that
they are not obstructed.
Side airbags
Description of side airbag s
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 211 Side airbag location in th e drive r's seat
The side airbags are located in the sides of the
front seat backrests
~fig. 211 and the rear
backrest* facing the doors. They are identified
by the word "AIRBAG". ....

228 Intellig ent technol ogy
- Never let the vehicle ro ll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Servotronic - advanced
power steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic power steering sys­
tem senses the road speed and electronically
adjusts powe r assistance to provide comforta­
b le and safe steering response exact ly match­
ed to the vehicle speed.
Power steering w ill not work if the eng ine is
off. As a result, the steering wheel w ill be hard
to turn.
The power steering fluid level is checked dur­
ing the scheduled ma intenance serv ices .
@ Note
If the re is an electronic malfunct ion, ser­
votronic
w ill still function like a conven­
tional power steer ing system, p roviding a
constant steer ing support force that is no
longer proportionate to the vehicle speed .
This is most noticeab le when turning the
steering whee l at low speeds (for examp le
when parking), -more effort will be re­
quired than usual.
- Be aware of the different than usua l
steering response and adjust your steer­ i ng force accord ingly.
- Have the prob lem checked and set right
by an Aud i dealer as soon as possible.
- When the engine is running , never hold
the steering whee l turned all the way to
the right or to the left for longer than
15
seconds . The power steer ing pump w ill
overheat the hydraulic flu id if you keep holding the steering wheel turned all the
way . This is likely to damage the power
steering system.
- If the powe r stee ring system sho uld fail
entirely, or if the engine is not running
(for example, whi le be ing towed), you
will still be able to steer the ve hicle.
However,
considerably more effort will
be required to do so .
- If the power steering system should
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immediately .
- The power steering system requ ires a
specially formulated hyd ra ulic fluid . The
powe r stee ring reservoir is the one locat­
ed farthest to the rear on the left s ide of
the engine comp artment r=;,
page 259.
T he correct fluid level in the reservoir is
important for proper functioning of the
power steering .
Driving with your
quattro
With all-wheel drive , all four wheels are driv­
en .
Gen eral information
With all-wheel drive, power is distributed to
all four wheels. This happens au toma tically
depending on your driving style and the road
condit ions at the time . See also r=;,
page 224 .
Winter tire s
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even wi th
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved dr iveability and brak­
ing : these tires must be mounted o n
all four
wheels. See also r=;, page 288, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also appl ies to veh icles
with all-wheel driver=;,

For year-round driv ing, antifreeze is added at
the factory for temperatures down to:
- - 31 °F (- 35 °C) USA
- - 40 °F ( - 40 °C) Canada .
If you mus t add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distilled water is recommended .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 257.
(D Note
-Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely cold.
If necessary, in­
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive Gl2++ or G13 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection . The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in damage not covered by your New Vehicle
Limited Warranty.

288 Tires and wheels
The relative performance of tires depends
upon the actual conditions of their use, how­
ever, and may depart significantly from the norm due to variations in driving habits, serv­
ice practices and differences in road character­
istics and climate.
Traction
The traction grades , from highest to lowest,
are AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢.&, .
Temperature
The tempera ture grades are A (the highest),
B, and
C, representing the tire's resistance to
the generation of heat and its ability to dissi ­
pate heat when tested under controlled condi­
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure~.&, .
The grade
C corresponds to a level of perform ­
ance which all passenger car tires must meet under the Federal Motor Vehicle Safety Stand­
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.
A WARNING
The temperature grade for this tire is es­
tablished for a tire that is properly inflated
and not overloaded . Excessive speed, un­
derinflation, or excessive loading, either
-
separately or in combination, can cause heat buildup and possible tire failure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F (7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true winter or "snow" tires, those
with very deeply cut tread . These tires should
only be used in pairs and be installed on all
four wheels . Make sure you purchase snow
tires that are the same size and construction
type as the other tires on your vehicle .
Your vehicle is equipped with all-wheel drive,
this will improve traction during winter driv ­
ing, even with the standard tires. However, we
strongly recommend that you always equip all
four wheels on your vehicle with correctly fit­
ted winter tires or all-season tires, when win­
ter road conditions are expected. This also im­
proves the vehicle's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire sizes . Use
only radial winter tires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
O .15 7 inch
(4 mm).
Only drive with winter tires under winter con­
ditions. Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7
°().

Please always remember that winter tires may
have a lower speed rating than the tires origi-
nally installed on your vehicle at the time it .,.
