-When installing the roof rack, make sure it
is only mounted on the designated locations
on the roof¢
fig. 66 .
- We recommend that you keep the installa ­
tion instructions for your roof rack system
together with your Owner's literature in the
vehicle.
Wh en should th e roof rack be remov ed ?
- Before going through an automatic car wash
(it is best to ask the car wash operator for
advice).
- When not in use, to reduce fuel consump­
tion, wind noise and to guard against theft.
8_ WARNING
- Use of an unapproved roof rack or incor­
rect mount ing of an approved roof rack
can cause the roof rack or the items at­
tached to it to fall off the roof onto the road.
- Objects fal ling from the roof of a vehicle
can cause a crash and personal injury .
- Only mount the roof rack on the desig­
nated locations on the roof¢
fig. 66.
- The roof rack system must be installed
exactly according to the instructions pro­
vided .
- When driving w ith a roof rack system,
changes to the center of gravity and wind
resistance can change the veh icle han­
dling and lead to a collision . Always
adapt you r driv ing and your speed to the
c u rrent conditions.
(D Note
- Your vehicle warranty does not cover any
damages to the vehicle caused by using
r oof racks or mount ing structures not
approved by Audi for your vehicle . T he
same applies to damage resulting from
incorrect roof rack installa tion.
- Always check t he roof rack moun tings
and hardware before each trip and dur­
i ng a trip to make sure everything is se­
curely tightened . If necessary, retighten
the mount ings and check the entire sys­
tem from t ime to t ime.
S eat s an d sto rage 63
-After mounting a roof rack system, or
when you transport objects on the roof
of your vehicle, the heig ht o f the veh icle
is naturally increased. Be careful when
dr iving under low bridges or in parking
garages for example. This cou ld cause
damage to the load and even the vehicle
itself .
- Make sure the open rear lid and the sun­
roof* do not come into contact w ith the
roof rac k.
Loading the roof rack
Always distribute loads evenly. Make sure
anything on the roof rack is securely tied
down.
"' Always distribute the loads on the roof rack
even ly.
"' Always attach items to the roof rack securely
befo re you dr ive off.
The maximum permissible roof we ight is
220 l b (100 kg) . The roof weight is the total
of the we igh t of the roof rack, t he attach­
ments and the cargo you a re carry ing . You
must a lso not exceed the max imum load
weight for the roof rack yo u are using .
When using a roof rack system which has a lower load ca rrying capacity, you must not use
u p the tota l maximum permissible load car ry­
ing capacity specified above . Instead, you
sho uld load the roof rack system only to the
max imum capacity specified by the manufac ­
turer of the roof rack system.
8_ WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
du ring ha rd b raking o r in a coll is ion and
cause ser ious persona l injury.
- Make sure the roof rack is installed exact­
ly as specif ied above ¢

Automatic Transmission
tiptronic
Introduction
The automatic transmission is controlled elec­
tronically. The transmiss ion upsh ifts or down­
shifts automatically depending on which drive
program is selected.
When a
moderate driving style is used, the
transmission selects the most econom ical
driving mode. It will then change up early and
delay the downshifts to give better fuel econ­
omy.
The transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed .
If desired, the driver can also select the gears
manually (tiptronic mode) ¢ page 107.
In the tiptronic transmission, power is trans­
ferred by a torque converter .
Selector lever positions

Before you move the selector lever to R, press
both the button in the hand le of the selector
lever
and the brake pedal at the same time .
When the ignition is on, the backup lights illu­
minate when the selector lever is moved into
R.
N -Neutral
The transmission is in neutral in this position.
Shift to this position for standing w ith the
brakes applied ¢
& in Driving the automatic
transmission on page 105 .
When the vehicle is stationary or at speeds
below 1 mph (2 km/h), you must always apply
the footbrake before and whi le mov ing the

D/S -Normal position for driving forward
In the D/S position, the transmission can be
operated either in the norma l mode D or in
the sport mode S. To select the sport mode S,
pull the selector lever back briefly. Pulling the
lever back again will se lect the norma l mode
D. The instrument cluster display shows the
selected driving mode.
In the normal mode D, the transmission auto­
matically selects the suitable gear ratio. It de­
pends on engine load, vehicle speed and driv­
ing style.
Select the sport mode S for sporty driv ing.

The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not d rive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
... Avoid high engine speeds.
From 600 to 1,000 mile s (1 ,000 to
1,500 kilometers):
... Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in period
.,. Do not rev the eng ine up to high speeds
when it is cold. Th is app lies whether the
transm ission is in N (Neutra l) or in gear.
After the break-in period
... Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
c:> page 10.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
in . How well this break- in process is do ne de­
pends to a conside rable extent on th e way the
ve hicl e is driven during the first 1,0 00 miles
(1, 500 k ilome ters).
0 Note
E xtremely high engi ne speeds are auto­
mat ica lly reduced. However, these rpm
lim its are progr amme d for an engine well
r u n- in, not a new engine .
{® For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ­
ment.
, New tires
If your vehicle is runni ng on new tires, drive
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
A WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be s ure to remember
this dur ing the fi rst 350 mi les ( 500 kilo ­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
braking .
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled.
New brake pads have to be "burnished in" be­
fo re t hey have optima l grab
c:> A .
During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak­
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop­
pi ng power and m us t be "broke n-in " dur­
i ng the in itial 1 00 to 150 mi les (15 0 to
2 00 k ilometers) of no rma l city driving . You
can compensate for this by pressing th e
br ake peda l mo re f irm ly . This also applies
l ater when new pads are installed.

Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
T his is especially true for vehicles with low­
slung chassis (sports chassis) * and fully load­
ed veh icles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any h igher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
- Vehicle components such as the eng ine,
transmission, suspension or e lectrical
system can be severely damaged by driv­ ing through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not s top the veh icle, drive in reverse
or switc h 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 driving thro ugh sa lt water because
-
~ it can ca use corrosion. ,....,

Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can help ensure that it is not
overstressed unnecessar ily during sporty dr iv­
ing.
When warming up, the vehicle is dr iven at a
maximum engine speed of 6000 RPM in order
to raise the engine o il temperature to a mini­
mum of 140
°F (60 °() . The t ires a lso on ly
reach the ir full road holdi ng capabi lity on ce
they have warmed up.
The cooli ng fan can cont inue to run in your ve­
hicle after the engine is switched off . Howev­
er, driving the veh icle to coo l it down is pa rti c­
ul arly important. Dur ing spo rty driving , the
engine and b rakes, the exhaust system, and
the transmission a ll become extremely hot.
Before you park the vehicle, you should drive
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down .
Catalytic converter
App lies to vehicles: wi th gaso line e ngi ne
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
"' Always use lead-free gasoline c:> page 206,
Fuel supply .
"' Never run the tank down all the way to emp­
ty.
"' Never put too much mo to r o il in yo ur eng ine
c:> page 21 S, Adding engine oil "t:::r..
"' Never try to push -or tow -start you r vehicle .
T he catalytic co nve rter is an efficient "clean ­
u p" dev ice bui lt into t he exhaus t system of
the ve hicle . The cata lytic converter bu rns
many of the pollutants in the exha ust gas be ­
fore they are re leased into the atmosphere.
T he exclus ive use of unleaded fuel is c ritical ly
i mportant for the life of the catalyt ic convert -
er and proper functioning of the engine .

_& WARNING
The temperature o f the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exha ust tail p ipes once
they have become hot. This could result in burns .
- Do not park or operate the veh icle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold , exhaust p ipes, catalytic con ­
verte r or heat shie lds. D uri ng d riving, the
substance used for undercoating cou ld
over heat and cause a fire .
(I) Note
- Be aware that just one tank filling with
l eaded fuel will already seriously de­
grade the perfo rmance of the cata lytic
conve rter.
- Do not exceed the correct engine oil leve l
¢page 215.
- Do not d rive until the fuel tank becomes
completely empty. The eng ine could mis­
fire. Unburned f uel could a lso ge t in to
t h e exhaus t sys tem and this could cause
the ca talyt ic converte r to ove rheat.
- Do no t switch off the ign ition wh ile the
vehicle is moving.
- Do no t continue to operate yo ur vehicle
u nder these condi tions, as otherw ise fuel
can reac h the catalytic converter . This
could result in overheating of the co n­
verter, req uiring its replacement.
- To assure efficient operation of the Emis ­
sion Control System :
- Have your veh icle maintained properly
and in accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir the function of the em
ission cont ro l
system and could lead to damage .
~ For the sake of the env ironment
Even when the Emiss ion Con trol Sys tem is
operat ing proper ly, the exha ust gas can
have a sulfur-li ke ex haust gas smell under
some ope rat ing states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or fil ling the tank with lead -free super
grade gasoline .
Shutting down vehicle
If you would like you r vehicle to remain inop­
erative for a longer per iod of t ime, contact an
Audi o r other spec ia lized dealer. They can ad­
v ise you on ne cessa ry precautions e .g. co rro­
s io n preven tion , maintena nce and s to rage.

Operate your vehicle
economically and
minimize pollution
General
Your p ersonal style of driving will determine
the economy of your vehicle , as well as ex ­
haust and nois e le ve ls .
Fu el economy, environmenta l impact, and
wear on your engine , brakes and tires largely
depend on three factors:
- your personal d riving style
- operati ng conditions
- technical limitat ions
If you an tic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt io n by 10 -15 percent . This sec ­
t ion w ill give you some tips on how you can
help the e nvir onment 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
celerating. If you anticipate what is going to happen next, you will need to brake less and,
thus , accelerate 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 maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
gine 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
ditions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
~ Shut the engine off when you are not driving
the vehicle.
Driving and environment 199
~ 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 traffic lights that have
long waits on red. Turning the engine off for
just 30 -40 seconds saves more fuel than is
burned starting the engine 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
would go unheeded. Extended idling also
produces heat, which could 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
Audi dealer helps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven .

200 Driving and en vir onm ent
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess o il consumption.
This a lso applies to fuel consumption and en­
gine output.
0 Note
- Have yo ur vehicle maintained 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 funct ion of the
emission control system and could lead
to damage .
- Do not alter or remove any component of
the Emi ssion Control System unless ap­
proved by the manufacturer .
- Do not alter or remove any dev ice, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emiss ion Control System
and othe r important veh icle compo­
nen ts.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.. Try to avo id driving short d istances with a
co ld eng ine .
The engine and ca talytic conver ter have to
reach their optimal
op erating temp eratur e to
reduce fuel consumption and noxious emis­
sions effect ively.
Jus t after s tarting, a cold engine in a mid-size
car only achieves a fuel economy of 6 -8 miles
per gallon (30-40 l/100 km) . After about a
ha lf a m ile, fue l economy climbs to 12 mpg
(20 l/100 km). Afte r abo ut
2 .5 m iles (4 km),
the eng ine is at its proper ope rat ing tempera­
ture and fue l economy has reached a norma l
l eve l. So you can see that you should avoid
short trips whenever possib le . T
he
ou tsid e tempe rature is also critical in this
regard . Your car consumes more fue l in the
winter than in the summer.
