toring the Advanced Airbag System.
- Take the chi ld restraint off the front pas­
senger seat and install it prope rly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not s tay on
whenever the ignit ion is swi tched on.
- Imp roper installation of ch ild restraints
can reduce their effectiveness or even
preven t them from providing any protec­
tion.
- An improperly installed ch ild restra int
can interfere with the airbag as it de­
ploys and seriously injure or even ki ll the
child.
-Always carefu lly follow the manu fact ur­
er's instructions p rov ided with the chi ld
safety seat or carrier .
- After checking to make sure that the child restraint is properly insta lled, make
certa in that the ch ild restraint is correct­
ly recognized by the capac itive passenger
detection system in the front passenger
seat and that the
PASSENGER AIR BAG

position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
A WARNING
Rearward-facing child restraints:
- A child in a rearward-facing child safety
seat installed on the front passenger
seat will be seriously injured and can be
killed if the front airbag inflates -even
with an Advanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
- Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on .
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your Audi
dealer.
Activating the convertible locking retractor
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­
er's instructions when installing a child re- straint in your vehicle. To activate the conver­
tible locking retractor:
.,. Place the child restraint on a seat, prefera­
bly on the rear seat.
.,. Slowly pull the belt
all the way out.
.,. Route it around or through the child re­
straint belt path
¢ A -
.,. Push the child safety seat down with your
full weight to get the safety belt really tight .
.,. Insert the belt tongue into the buckle for
that seating position .
.,. Guide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat.
.,. You should hear a "clicking" noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt out of the retractor. The con­
vertible locking retractor is now activated .
.,. Make sure that the red release button is fac­
ing away from the child restraint so that it
can be unbuckled quickly.
.,. Pull on the belt to make sure the safety belt
is properly tight and fastened so that the
seat cannot move forward or sideways more
than one inch (2.5 cm).
A WARNING
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash.
- Always make sure that the safety belt re- tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash.
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
A loose child safety seat can fly around
during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched

Tether anchors and tether straps
Fig. 159 Te the r ancho rs: recess fl aps be hind the rear
sea tback s
The tether anchors for the rear seating posi­
tions are located in recesses in the rear win­
dow shelf
c:> fig. 159
A tether is a straight or V-shaped strap that
attaches the top part of a child restraint to
special anchorage points in the vehicle.
T he purpose of the tether is to reduce the for­
ward movement of the child restraint in a crash, in order to help reduce the risk of head
injury that could be caused by striking the ve­
hicle interior.
Forward facing child restraints manufactured
after September 1, 1999, are required by U.S .
federal regulations to comply with new child head movement performance requirements.
These new performance requirements make a
tether necessary on most new child safety
seats.
A WARNING
Improper installation of child restraints
will increase the risk of injury and death in
a crash . -
Always follow the instructions provided
by the manufacturer of the child re­
straint you intend to install in your Audi.
- Improper use of child restraint anchors
(including tether anchors) can lead to in­
jury in a collision. The anchors are de­
signed to withstand only those loads im­
posed by correctly fitted child restraints.
- Never mount two child restraint systems
on one LATCH lower anchor point.
- Never attach two child restraint systems
to one tether strap or tether anchorage .
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether ancho­
rages to secure safety belts or other
kinds of occupant restraints.
- Never secure or attach any luggage or
other items to the LATCH lower ancho­
rages or to the tether anchors .
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
Audi dealer.

Audi pre sense
Preventative passenger
protection
Applies to vehicles: with Audi pre sense
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking): the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof* : the
windows and the sunroof* close leaving a
small open gap .
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the deploy­
ment time is adapted in dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the limits of the system, the likelihood of a colli ­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the follow ing functions can be
tr iggered:
- Audi braking guard
c::> page 85
- Tightening the safety be lts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated. If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions in
Audi pre sense front and Audi pre sense rear .
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected.
_& WARNING
-=
Audi pre sense cannot overcome the laws
of physics. It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks . This will increase
the risk of a coll is ion and serious personal
in juries .
- The sensors cannot always detect all ob­ jects. This increases the risk of a colli­
sion.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path
c::> page 79.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from gua rd rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac­
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly.

Braking
General information
What affects braking efficiency?
Ope rating condition s and dri ving h abit s
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits ¢.&, . On ve­
hicles that are either dr iven mostly in stop­
and-go c ity traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often th an specified in
the
Warran ty & Maintenan ce boo klet. Failure
to have yo ur brake pads inspected can result
in reduced brake performance .
On steep slopes, you sho uld use the braking
effect o f the engine . This way, you prevent un ­
necessary wear on the b rake system. If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter­
vals.
Mo istur e or road salt
U nder certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few carefu l brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered

Appl ies to vehicles : wit h all- wheel d rive
With all-wheel drive, all four wheels are driv ­
en.
General information
With all-whee l dr ive, power is distributed to
all four wheels. This happens automatically
depending on your driving sty le and the road
conditions at the time . See also
c!.> page 184.
The all-wheel drive concept is designed fo r
high engine power. Your vehicle is exception ­
ally powerful and has exce llent driving charac-

teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precaut ions ¢&. .
Winter tires
When driving in the winter, your vehicle with
all-wheel drive has an advantage,
even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea ­
son tires) for improved driveability and brak­
ing : these tires must be mounted on
all four
wheels.
See also ¢ page 246, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles
with all-wheel drive¢
page 247, Snow
chains.
Replacing wheels/tires
Vehicles with all-wheel drive must always
have tires of the same size. A lso avoid tires
with different tread depths . For detai ls see
page
c:> page 242, New tires and replacing
tires and wheels.
Off-Road driving?
You r Audi does not have enough ground clear­
ance to be used as an off-road vehicle . It is
therefore best to avoid rough tracks and un­
even terrain as much as possib le. Also refer to
c:> page 193.
A WARNING
Always adjust your driving to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippe ry road surfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning) . If this should occur, you
will have no warning from a sudden

With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use other MMI func­
tions, the battery is being discharged .
If starting capability is jeopardized due to en­
ergy consumption, the following warning ap­
pears in the MMI display :
Please start the engine soon or the system
will be turned off.
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you wish to continue using the functions , you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is being driven , the battery can be ­
come discharged . This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili­ brium, consumers which require especially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular require a great deal of energy. If you
notice , for example , that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched
off. These systems will be available again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has
been increased slightly. This is normal and not
a cause for concern . By increasing engine idle
speed the additional energy required is gener­
ated and the battery is charged.

194 Driving and en vironm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
sto re the full braking effect.
@) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water .
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion will give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less . Let the vehicle coast
whenever possible - for example when you see
that the next traffic light is red.
