Single-trip memory (Trip computer 1 )
The sing le -t rip memory stores the tr ip info r­
ma tion from the time the ig nition is tu rned on

light sensor checked as soon as possible at a
dealership.
Adaptive light *
The benefit of adaptive l ight is that the curve
and the edge of the road are better i llum inat­
ed . The adaptive light is contro lled automati­
cally, depending on vehicle speed and steering
wheel angle.
When driving a round bends, the head lights
are contro lled according to steering wheel an­
g le . So that there is no black area ahead of the
ve hic le, the two main beams pivot at different
angles. The system works above a speed of
about 6 mph (10 km/h).
Com ing home /le avi ng home function *
The function is swit ched on when the switch is
in the AUTO* position and the function is
shown as active in the driver information sys­
tem.
The
coming hom e function illuminates the
area around the vehicle when the ign ition is
switched off and the driver's door is ope ned.
The length of time the lights remain on can be
set in the menu display
( Illumination > Exte­
rior lights > coming home ).
The leavi ng home function i lluminates the
area around the vehicle when unlocking it.
A WARNING
- Never use dayt ime running l ights to see
where you are going. They are not bright
enough and w ill not let you see far
enough ahead for safety, especially at
dusk or when it is dar k. Always switch on
the low beams at dusk or when i t is dar k.
- Automatic headlights a re only intended
to assist the dr iver. They do not re lieve
t he driver of his responsibi lity to check
t he headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
and rain cannot be detected by the light
sensors. So a lways switch on the head­
lights under these weather cond itions
and when driving in the dark
jO .
Clear vis ion 49
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists.
- Always turn on the headlights so that

- Please observe legal regulat ions w hen
using the ligh ting systems des cribed.
(D Tips
- T he light sensor for head light control is
located in the rear view mirror mount.
Do not apply any stickers to t he wind­
shield in th is area to preven t malfunc­
tions or fa ilures.

- I f you remove the igni tion from t he igni ­
t ion lock while the headligh ts are s till
on, a buzzer wi ll sound as long as the
driver's door is o pen to remind yo u to
t u rn off the lights.
- Always observe the specific local regula ­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam f unction is also available, but w ith
one restrict ion: If you have not sw itched
the high beams back to low beams dur­
ing automatic headlight operation (for
example, after d riving throug h a tunnel),
only the low beams come on the next
t ime au tomati c headlights a re swi tched
on. To use the high beams , you firs t have
t o pull the hig h beam lever back and
then push the lever fo rward again .
- In coo l or damp weather, the inside of
the headlights, turn signals an d tail
lights can fog over due to the tempera­
t u re difference between the inside and
outside. They w ill clear shortly after
switching them on. This does not affect
the se rv ice life of the lighting.

C lean you r wiper blades regularly with a wind ­
shield washer solution to prevent streaking. If
the b lades are very dirty, for examp le with in­
sects, carefully clean the b lades with a sponge
or a soft brush.
If the wiper blades begin to streak the wind­
shield, this cou ld be caused by residue left on
the windshie ld by automatic car washes.
Fill the wi ndshield washe r container with a
spec ial solutio n availab le at your aut horized
Audi dealer to remove the resid ue .
Be sure to inspect t he condition of your wiper
blades regularly. For safety reasons, rep lace
your wiper blades once or twice a year if nec­
essary . See yo ur authorized Aud i dealer for re­
placement blades.

- 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
&

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 .
Shutting down vehicle
If you would like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized deale r. T hey can ad­

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 eng ine, brakes and tires largely
depend on three factors:
- your personal d riving s tyle
- operati ng conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut you r
fuel consumpt io n by 1O-lS percent . T his sec­
tion w ill give you some tips on how you can
help the env ironment and your po cketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROT ECTI ON AGENCY
( E PA) a nd Tra nsp o rt Canada may no t corre­
spond to your actual consump tion on the
r oad, which will va ry 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 acce lerating and braking .
Vehicles use the most f ue l when they are ac­
ce le rat ing. If you ant icipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less . Let the vehicle coast
whenever possible - for examp le when you see
that the next traff ic light is red.

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 227.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile driving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 197
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 186, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
