Opening and closing Keys
Key set
Fig. 28 Key set
@ Master key with remote control and
integrated mechanical key
You can centrally lock and unlock your vehicle
and start the engine with the master key with
remote control. A mechanical key is integrat­
ed in the master key~
page 39.
® Emergency key
The emergency key is not intended for con­
stant use.
It should only be used in an emer­
gency . Keep it in a safe place and do not carry
it on your key ring .
Key replacement
If you lose a key, contact your authorized Audi
dealer immediately to have the
lost key disa­
bled. Be sure to bring all your keys with you.
Data in the master key
During driving, service and maintenance-rele­
vant data is continuously stored on your mas ­
ter key. Your Audi service adviser can read out
this data and tell you about the work your ve­ hicle needs. This applies a lso to vehicles with
conven ience key*.
Per sonal comfort settings
If two people use one vehicle, it is recom­
mended that each person always uses "their
own" master key . When the ign ition is turned
off or when the vehicle is locked, personal
conven ience settings for the follow ing sys-
Opening and closing 3 7
terns are stored and assigned to the remote
master key.
- Climate contro l
- Centra l locking system
- Seat memory*
- Parking system*
-Adaptive cruise control*
- Audi side assist*
- Audi drive se lect*
The stored settings are automatically recalled
when you unlock the vehicle, when you open
the doors or when you turn on the ignit ion.
A WARNING
-
- Do not leave your vehicle unattended
with the key in the ignition lock. Entry by
unauthorized persons could endanger
you or result in theft or damage the vehi­
cle . Always lock all doors and take the
key .
- Do not leave ch ildren unattended in the
veh icle, especially with access to vehicle
keys . Unguarded access to the keys pro­
vides children the opportun ity to start
the engine and/or activate vehicle sys­
tems such as the power windows etc. Un­
supervised operation of any vehicle sys­
tem by children can result in serious In­
jury.
- Do not remove the key from the ignition
lock until the vehicle has come to a com­
plete stop. Otherwise the steering col­
umn lock could suddenly engage -caus­
ing the risk of an accident.
@ Tips
- Th e operation of th e remote control key
can be temporarily disrupted by interfer­
ence from transmitters in the vicinity of
the vehicle working in the same frequen­
cy range (e .g. a cell phone, radio equ ip­
ment).
- If you open the driver's door with the key
left in the ignit ion lock, a chime w ill
sound. Th is is your reminder to remove
the key and lock the door.

84 Warm and cold
With this setting, you attain maximum com­
fort in the least amo unt of time. Change this
setting, as des ired, to meet yo ur persona l
needs.
The climate controls are a combination of heating, venti lation and cooling systems,
which automatica lly reduce hum idity and cool
the air inside your vehicle.
The climate control automatically maintains a
temperature once it has been set . The tem­
perature of the air from the vents, fan speed
(air volume) and air distribution are also auto­
mat ically adjusted . The system also takes into
account strong sunshine so that manual ad­
justment is not necessary . So in almost all
cases,
autom atic mo de offers the best cond i­
tions for the comfo rt of the occupants at all
times of the year¢
page 86.
Please note the following :
Turn on the air cond itioner to reduce hum idity
in the vehicle . Th is also prevents the w indows
from fogging up.
When the outside temperature is high and the
a ir is very hum id,
conden sation from the
evaporator may drip under the vehicle. This is normal and does not indicate a leak .
If the outside temperature is low, the fan nor­
mally only switches to a h igher speed once
the eng ine coolant has warmed up sufficient­
ly .
The air conditioner temporarily switches off
when you drive off from a standstill using full
thrott le to save engine power.
The compressor also switches off if the cool­
ant temperature is too high, so that the en ­
g ine can be adequately coo led under extreme
loads.
Du st and pollen filter
The dust and pollen filter (a combined particle
fi lter and activated charcoal filter) reduces or
prevents outside air pollut ion (dust, or po llen)
from entering the vehicle . T
he dust and po llen fi lter must be changed at
the interva ls specified in your Mai ntenance
booklet , so that the air conditioner can prop­
erly work.
If you drive your vehicle in an area with a high
degree of air pollution, the filter may need to
be changed more frequently than specif ied in
your Audi Warranty
& Maintenance book let. If
in doubt, ask your authorized Audi Service Ad­
visor fo r advice .
Key recognition
The current climate contro l settings are auto ­
matically stored and assigned to the remote
key
Energy management
T o prevent the battery from being discharged
and to resto re the ba lance of energy, compo ­
nents which require large amo unts of energy
are temporarily cut back or switched off
¢ page 211. Heat ing systems in particular re­
quire a great deal of energy. If you notice, for
example, that the rear w indow heater is not
heating, then it has bee n tempora rily cut back
o r switched off by
energy managemen t.
These sys tems are available again as soon as
the energy balance has been resto red.
.&_ WARNING ~
Reduced visibi lity is dangerous and can
cause accidents .
-
- For safe d riving it is very impor tant that
all windows be free of ice, snow and con ­
densation .
- Comp lete ly fam iliari ze yourse lf with the
proper use and function of the heating
and venti lation system and especially
how to defog and defrost the w indows.
- Never use the windshield wipe r/washer
system in freez ing weather unt il you
have warmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the w ind-
shie ld and red uce visib ility.

This automatic adjustment process will cause
a
slight vib ra tion of the brake pedal and some
noises to alert you that vehicle speed must be
adapted to existing road and traffic condi­
tions.
A WARNING
Although the ABS is very effective, always
remember that braking capability is limit­
ed by t ire traction . A lways adjust your dr iv­
ing speed according to the road and t raff ic
conditions. Do not let the extra sa fety af­
forded by the ABS tempt you into taking
extra risks. The ABS cannot overcome the
laws of physics .
(D Tips
-If ABS is not functioning properly, a
warning light will come on . See
~ page 16.
-If a fault occu rs in the ABS, the EDL is al­
so not functioning . This is indicated by
the ABS warning light .
Brake assist
Brake assist is designed to achieve the opti­
mum broking effect.
Brake assist helps to increase the effective
brak ing power and thus to achieve a shorter
stopping distance. If the driver presses the
brake peda l very quick ly, brake assist auto­
mat ica lly boosts the braking force to the max­
imum level, up to the point where the anti­
lock brake function (ABS) intervenes to stop
the wheels from locking . You should then
keep the brake pedal pressed u ntil the vehicle
has braked to the required speed . Brake ass ist
sw itches itself off as soon as you release the
b rake peda l.
A WARNING
Please remembe r that the accident r is k al­
ways increases if yo u drive too fast, espe ­
cially in corners or on a s lippery road, or if
you fo llow the vehicle ahead of you too
close ly. Increased risk of an accident can-
Int ellig ent technolog y 209
not be compensated for even by brake as­
sist, so always maintain a safe speed.

advanced power
steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
T he advanced Servotronic ® power steer ing
system senses the road speed and elect ron i­
ca lly adjusts power assistance to provide com­
fortab le and safe ste ering response exact ly
matched to the vehicle speed .
Power steering will not work i f the engine is
off. As a result, the stee ring wheel will be hard
to turn .
T he power steering fluid level is checked d ur­
ing the schedu led maintenance services .
(D Note
If there is an e lectronic malfunction, ser ­
votronic
will s till function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onger proportionate to the vehicle speed.
This is most noticeable when turning the
steering wheel at low speeds (for example
when parking), -more effort w ill be re­
q uired than usual.
- Be aware of the different than usual
steering response and adjust your steer ­
ing force acco rdingly .
- Have the problem checked and set right
by an Audi dealer as soon as possible.
(D Tips
-Whe n the engine is running, never hold
the steering w heel turned all the way to
the rig ht or to the left for longer t han 15
seconds. The powe r steering pump will
overheat the hydraulic fluid if you keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering system .

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not continue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
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, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your personal driving style
- operating conditions
- technical lim itations
I f you anticipate what you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 215
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION 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
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.. Avo id unnecessary accelerating and brak ing .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you ant icipate what is going to
happe n next, you will need to brake less and,
t hu s, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic 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 .
Accelerat ing gently reduces fuel consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

216 Driving and environment
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 vehicle by letting the
engine run at idle .
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rail ­
road crossings, or at traff ic lights that have
l ong wa its on red. Turning the engine off for
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However , wear
and noxious emissions 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
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it runs properly and economically . The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of oi l used is re lated to engine
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.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances with a
cold engine .
The engine and cata lytic converter have to
reach their optimal
operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km), ll>

220 Trailer towing

provided by Aud i.
Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
a trailer because of the additional weight and
different weight distribution. Safety, perform­
ance and economy wi ll greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic. Keep practicing until you have become completely familiar with the way
your vehicle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trai ler genera lly requires
steering action opposite to that when backing up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turn ing radius .
When passing, remember that you cannot ac­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your tra iler before chang­
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes .
(D Tips
-Do not tow a tra iler during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load
q page 293.
Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.. App ly the foot brake.
.. Have someone place chocks under both the
vehicle and the trailer wheels .
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load.
.. Turn the wheels towards the curb.
.. App ly the parking brake.
.. Place an automatic transmission* in
P, re­
spectively a manual transmission in first or reverse gear.
When restarting after parking:
.. App ly the foot brake.
.. Start the engine.
.. Move the se lector lever to
D , respectively a
manual transmission in first gear .
.. Release the parking brake and slow ly pu ll
out and away from the wheel chocks.
.. Stop and have someone retr ieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto­
matic transmission* to
P before applying
the parking brake and before blocking the
whee ls, you may have to use more force
lat er to move the lever out of the
P posi­
tion.

The best way to remove snow from windows
and mirrors is to use a brush. Use a non-abra­
sive
plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mir­
rors.
The windows must not be cleaned with insect
remover or wax sin ce these can interfere with
the function of the windshield wiper blades
(chatter).
Oil, grease, or silicone residue can be removed
with
glass cleaner or silicone remover. How­
ever, wax residue require s the use of a special­
ly formulated solvent. Please contact your au­
thor ized Audi dealer for advice on safe prod­
ucts for wax removal.
Windows should also be cleaned on the inside
at regular intervals.
Never dry windows with the same chamois
that you use to dry painted surfaces. Wax resi­
due on the chamois can impair vision through
the windows.
A WARNING
-Always read and heed all WARNINGS and
other information
r::.> page 221.
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
- Never use warm or hot water to remove
snow and ice from windows and mirrors.
This could cause the glass to crack.
- To prevent damage to the wires of the
rear defogger, do not place any adhesive
stickers on the inside of the rear window
over the wires.
- To help prevent dirt from scratching the
window, always scrape in a forward di­
rection -pushing the scraper away from
you -never back and forth.
Cleaning and protection 225
-Water leaking from the inside of the rear
windows may damage sensitive electrical components located either under the
rear parcel shelf or in the rear trunk area.
Always ensure that water never leaks
through the body section of the vehicle.
You can do this by using waterproof pro­ tection over the vehicle's electrical com­
ponents (e.g. when installing window
tinting) .
- Damage or malfunction of electrical
components due to water damage or any
other outside influence is not covered by
the Audi New Vehicle Limited Warranty.
See your Warranty
& Maintenance book­
let for additional details about your war­
ranty.
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
.,. Wash the wheels with a sponge or hose
brush every other
week .
.,. For deep cleaning afterwards, use only a
dedicated
acid-free cast alloy wheel cleaner.
.,. Rub a coat of
liquid wax onto the rims every
three month. Be sure to reach and treat all
parts of the rim.
To preserve the decorative appearance of the
cast alloy wheels, some special care is neces­
sary. In addition to road dirt and salt, brake
dust is also corrosive . If left on for too long,
brake dust can cause pitting.
Use only special
acid-free cleaners formulated
for alloy rims. Safe products are available at
your authorized Audi dealer. Never leave the
cleaner on the rims longer than specified on
the label. If not rinsed
off promptly, the acid
contained in some cleaners can attack the
threads on the wheel bolts.
Never use abrasive or metal polishing clean­
ing agents. If the protective coating has been
chipped, e.g. by kicked up road dirt, touch it up as soon as possible . .,..
