c::> fig. 162
A tether is a straight orV-shaped strap that
attaches the top part of a child restraint to
specia l anchorage poi nts in the veh icle.
T he purpose of the tether is to reduce the for ­
ward movement of the ch ild restra int in a
crash, in o rder to he lp reduce the risk of head
injury that could be caused by s triking the ve ­
h icle inter io r.
Forward facing child restraints manufactured
after Septembe r 1, 1999, are required by U.S .
federal regulations to comply with new c hild
h ead movement performance requi rements.
These new performance requirements make a
tether necessary on most new chi ld safety
seats .
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of injury and death in
a crash.
Child S afety 185
-Always follow the instr uctions 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 coll ision. The anchors are de­
sig ned to withstand only those loads im ­
posed by correctly fitted child restraints .
- Never mount two child restraint systems
on one LATC H lower anchor point.
- Never attach two child restraint systems
to one tether strap or tether anchorage .
- Never attach a te ther strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether ancho­
rages to secure safety belts or ot her
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 fac ing
child safety seat on the front passenger
seat because of exceptional c ircumstan­
c e s and the
PASSENGER AIR BAG OFF
light does not come on and s tay on, im­
medi ately insta ll th e rear-fac ing c hild
safety seat i n a rea r seating position and
have the airbag system inspected by your
Aud i dea ler.

Audi pre sense Preventative passenger
protection
App lies to veh icles: with Audi p re se nse
Audi pre sen se can ini tiate steps to help pro­
t ect vehicle occupants in certain situations.
The funct ions descr ibed depend on equipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
cert ain driving situations :
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensione rs. 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 Audi 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 following functions can be
triggered:
-Audi braking guard
¢ page 84
- Tightening the safety belts
- 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 col lision with the vehicle
coming from behind is also calcu lated. If the
Audi pre sense 187
risk of a co llision is detected, the following
functions can be triggered :
- Tightening 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 Aud i pre sense rear .
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ate ly to have the malfunction corrected.
A 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 r isk of a coll is ion and serious personal
injuries .
- The sensors cannot always detect all ob­ jects . This increases the risk of a colli­
s10n .
-Audi pre sense does not detect people or
an imals or objects that are crossing the
veh icle's path ¢
page 78.
-The radar sensor's v is ion can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard 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.
Q) 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
Wha t affe cts bra king effici ency?
-
Operating conditions and driving habits
The brakes on today's automobiles a re still
subject to wear, depending largely on operat­ i ng co nd it io ns and driving habits ¢,& . On ve­
hi cles that a re e it h er dr iven most ly in stop­
and-go city t raff ic or are dr iven hard, the
br ake pa ds should be check ed by yo ur au thor­
iz ed Audi dea ler m ore often th an spec ified in
the
Warranty & Maintenance booklet. Failure
to have yo ur brake pads ins pected can result
in reduced brake performance .
On stee p slopes, you sho uld use the br aking
e ff ect o f the engine. This way, you prevent un ­
necessary wear on t he brake system. If you
must use your bra kes, do not hold the brakes
down cont in uous ly. Pump the brakes at inter­
vals.
Moisture or road salt
U nder certa in conditions, for exam ple, when
driving th roug h water or very heavy rain, or
even after washing your veh icle , the b raking
effect can be reduced due to m oist ure (or in ..,.

pressed considerably harder to make up
for the lack of booster assistance.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering.
Power steering adapts electronically based on
the vehicle speed .
Indicator lights and messages
• Steering defective! Stop the vehicle
If this indicator light turns on and stays on
and this message appears, the power steering may have failed.
Do
not continue driving. See your authorized
Audi dealer or other qualified repa ir facility
for assistance.
t -r- fl Steering: System malfunction! You may
c ontinue driving
If the indicator light turns on and the mes­
sage appears, the steer ing may be more diffi­
cult to move or more sensitive than usual.
Drive slowly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected.
@ Tips
If the . or t~fl indicator light only stays
on for a short time, you may continue driv­
ing .
Driving with your
quattro ®
Applies to vehicles: with all-wheel drive
With all-wheel drive, all four wheels are driv­
en.
General information
With all-wheel drive, 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¢
page 189. Intelligent technology 193
T
he all -whee l dr ive concept is designed for
high engine power. Your vehicle is exception­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions¢ ,&..
Winter tires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, even w ith
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 250, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles
with all-wheel drive¢
page 251, Snow
chains .
Replacing wheels/tires
Vehicles with a ll-wheel drive must always
have tires of the same size. Also avoid tires
with different tread depths. For deta ils see
page ¢
page 246, New tires and replacing
tires and wheels.
Off-Road driving?
Your 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 possible. Also refer to
¢page 197 .
A WARNING
Always adjust your dr iv ing 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 limited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippery road surfaces.

functions will be available again when you
switch on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off or use othe r MM I fu nc­
tions, the battery is being discha rged.
I f starting capability is jeopardized due to en­
e rgy consumpt ion, the fo llow ing warning ap­
pears in the MMI disp lay :
Plea se start the eng ine soon or th e sys tem
w ill b e turn ed off .
The warning ind icates that the system will be
turned off automatically after 3 m inutes . If
you wish to cont inue us ing the functions , you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is be ing driven, the battery can be­
come discharged . Th is happens mostly when
little energy is be ing generated and a great
deal consumed and the battery's state of
charge is no t optimal.
To br ing the energy balance back into equili ­
b rium, consumers which require especially
l arge amounts of energy are tempo rarily cut
back or swit ched off. Heating systems in par­
ticular requ ire a g reat dea l o f energy. If you
notice, fo r example, that the heated seats* or
the heated rear window are not heating, they have been temporari ly cut back or switched
off. These systems will be ava ilab le again as
soon as the energy balance has been restored.
You will a lso notice that engine idle speed has
been increased slightly . This is norma l and not
a cause for concern . By increasing engine idle
speed the add itiona l energy required is gener­
ated and the battery is charged.

198 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.

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"" Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­ tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
"" Shut the engine off when you are not driv­
ing the vehicle.
"" Do not warm up the veh icle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
bu rned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over-
Dri vin g and en vironm ent 199
'
heating o r othe r damage to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"" Have your veh icle serviced at reg ular i nter-
vals.
By having your veh icle regu la rly serviced by an
Audi dealer he lps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its sa fety and ability to
hold its value, it a lso affects
fuel con sump­
tion .
Check your oil e ach t ime you fill your tank .
The amount of o il used is re lated to eng ine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven .
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss io n cont ro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alter or remove any device, such
as heat shie lds, swit ches, ign it ion w ires,
valves, which are designed to p rotec t
your vehicle's Emission Control System
and other important vehicle compo­
nents .
