If the indicator light turns on and the message
appears, the steering may be more difficult to
move or more sensit ive tha n usual. The steering
wheel may also be at an angle when driving
stra ight.
Drive s lowly to your author ized Audi dealer or au­
thor ized Audi Service Fac ility to have the mal ­
function corrected.
kr.ij D ynam ic steering : Ini tializing
If the indicator lig ht ls b link ing and th is message
appears, dynamic steering* is being initialized.
Once you start the engine after this is finished,
the steering wheel will be easy to move. Re-in iti­
alization m ight be necessary if the steering wheel
was moved hard to the left and right wh ile the
ve hicle was not moving . The display turns off if
the initialization was successfu l.
{D) Tips
-If the . or '1:I indicator light only stays on
for a short time, you may continue driving .

steering, refer to¢ page 100.
Intelligent Technology
All wheel drive (quattro)
Applies to vehicles: with all wheel drive
In all wheel drive, all four wheels are powered.
General informat ion
In all whee l dr ive, the dr iving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as we ll as
the cur rent road conditions . Refer to ¢ page 187,
E lectronic Stabilization Control (ESC).
A center d ifferential d istribu tes the driving power
variab ly to the front and rear axle. It works to­
gether with selective whee l torque contro l, w hich
activates when driving through curves
¢ page 188. With the sport d ifferential*, power
distribution to the rear wheels is variable and can
be adjusted with drive select¢ page 100 .
The all wheel drive concept is designed for high
engine power. Your vehicle is except ionally pow­
erfu l and has excellent driv ing characteristics
both under normal driving conditions and on
snow and ice . Always read and follow safety pre­
cautions ¢
..1:)..
Winter tires
By using all wheel dr ive, your veh icle has good
forward motion with standard tires in w inter con­
ditions. However, in w inter we recommend using
winter or all seaso n tires on all four wheels, be­
ca use this will improve the brak ing effect.
Snow chains
If there are snow chain laws, snow cha ins must
also be used on veh icles w ith all wheel dr ive
¢ page 246 , Snow chains .
Replacing tires
For vehicles with a ll wheel drive, on ly wheels with
the same roll ing circumference should be used.
Avo id whee ls with different tread depths
¢ page 238, New tires or wheels .
Offroad vehicle?
Your Audi is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain. ..,.

Intelligent Technology
& WARNING
- Also, in vehicles with all wheel drive, adapt
your driv ing style to the curre nt road and
traffic conditions. Do not let the increased safety provided tempt you into tak ing risks,
because th is increases the r is k of an acci­
dent.
- T he brak ing ability of your vehicle is limited
to the tra ction of the wheels. In this way, it
is not diffe rent from a two whee l dr ive ve hi­
cl e. Do not be tempted to accelerate to a
high speed when the road is slippery this in­
c reases the risk of an acc ident.
- Note that on wet stree ts, the front wheels
can "hyd roplane" if d riving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, pay attention to the road
condit ions regardless o f you r sp eed to re­
duce the r is k of an accident.
Energy management
The starting ability is optimized
The energy managemen t system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a ve hicle wit h a co nven tional energy sys ­
tem is not driven for a long time, the batte ry is
d rained by equipment (for example t he immobi l­
izer) . In certain circumstances, there could may
not be eno ugh energy to start the engine.
Your vehicle is equipped with a n intelligent ener ­
gy management system for distr ibuting e lectric i­
ty. This s ignificantly improves the starting ability
and increases the b attery life.
The energy management system Is made up of
battery diagno sis , idling current management
and dynamic energy management .
Battery diagnosis
T he batte ry d iagnosis de term ines t he b att ery
ch arge level. The senso rs detect the battery, the
battery current, and the battery temperature.
192
The c urren t cha rge level and the performance of
the battery are determined based on this .
Idling current management
The idling current manageme nt decreases the
energy used while parked. Wi th the engine
swi tched off , it m anages t he energy dis trib ution
to the d ifferent e lectrica l components. Date from
batte ry diagnosis is taken into acco unt for this.
De pend ing on the b atte ry charge level, ele ctrical
equipmen t is switched off one item a fter the o th ­
er, to preven t the bat tery from draining and to
retain the starting ability .
Dynamic energy management
While driv ing , dynam ic energy manageme nt dis ­
t ribu tes the appr opr iate amo unt of energy to the
e lectri ca l eq uipment. It contro ls the battery
charge level so that more energy is not used then
is being generated in order to maintain an opti­
mal battery charge level.
(D Tips
- Ener gy management cannot overcome the
laws of p hysics . Note that the charge level
and length of the battery life are limited.
- Whe n the sta rting ability is endangered, the
(•) indicator light t urns on
~page 16.
What you should know
Maintaining the starting ability is the highest
priority.
A lo t of st ress is placed on the b attery when dr iv­
i ng sho rt distances, in t raff ic, and at cold times
of the year . A lot of energy is used but litt le is
generated. It is also critical when the engine is
not running but e lectr ica l equipment is sw itched
on. In th is case, energy is used but none is gener­
ated.
In sit uat ions like th is, ene rgy management w ill
active ly regulated the dis trib ution of energy.
Long periods without use
I f you do not drive yo ur vehicle for sever al days o r
weeks, e lectrica l equipment is gradua lly sca le d
back or sw itched off. This reduces ene rgy use and ..,.

ensures the vehicle wi ll be able to start after long
periods of time. Some convenience functions,
such as interior lighting or power seat adjust­
ment, may not be available under certain circum­
stances. These convenience functions will be
ava ilable aga in once you switch the ign ition on
and start the engine .
With the engine switched off
The battery will drain if you use functions s uch as
listening to the radio while the engine is sw itch­
ed off.
The vehicle's ability to start may be impaired by
the energy use, a message will appear in the In ­
fotainment system d isp lay.
The message indicates that the system will switch off automatically soon . If you wou ld like
to continue using the functions, you must start
the eng ine.
With the engine running
Although electrical energy is generated while
d riving, the battery can drain. This can happen
when little energy is generated, and much is used
and the charge level of the battery is not optimal.
To restore the balance of energy, components
that require large amounts of energy are tempo­
rari ly scaled back or switched off. Heating sys­
tems in part icu lar require a great deal of energy.
If you notice, for example, that the seat heating*
or rear w indow defroster is not working, then it
has been temporarily reduced or switched off .
These systems are available again as soon as the
e n ergy ba la nce has been restored.
In addition, you may notice that the idle speed
has slightly increased . Th at is normal and no
cause for conce rn. Due to the increased idling
speed , the additional required energy w ill be
generated and the battery will be charged.

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1,000 kilometers):
.,. Do not use full throttle .
.,. Do not drive at engine speeds that are more
than 2/3 of the maximum permitted RPM .
.,. Avo id high engine speeds.
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
.,. Speeds can gradually be increased to the maxi­
mum perm issib le road or engine speed.
During and after break-in period
.,. Do not rev the engine up to high speeds when it
is cold . This applies whether the transmission is
i n N (Neutral) or in gear .
After the break-in period
.,. Do not exceed maximum engine speed under
any circumstances.
.,. Upshift into the next higher gear
before reach­
i ng the red area at the end of the tachometer
scale~
page 10 .
During the first few hours of driving, the engine's
internal friction is higher than later when all the
mov ing parts have been broken in. How well this
break- in process is done depends to a considera­
b le extent on the way the vehicle is d riven during
the first 1,000 miles (1,500 kilometers).
(D Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm lim its are
programmed for an engine we ll run-in, not a
new engine .
194
® For the sake of the environment
Do not drive with unnecessarily high engine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
New tires
If your vehicle is running on new tires, drive par­
ticularly careful for the first 350 m iles (500 kilo­
meters) after f itting .
.8, WARNING
New tires tend to be slippe ry and must also
be "broken-in". Be sure to remember this dur­
ing the first 350 mi les (500 kilometers).
Brake gent ly. Avoid following closely behind
other ve hicles or other situations that might
require sudden, hard braking.
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 spo ilers and exhaust system
parts do not bottom out and get damaged .
-
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
driving through water, for examp le on flooded
roads:
- The water must not be any highe r than the bot­
tom of the vehicle body.
- Do not drive faster than walk ing speed .
.8, WARNING
After driving through water or mud, the brak­
ing effect can be red uced due to moisture on
the brake discs and brake pads . A few careful
brake applications should dry off the brakes.

CD Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Always switch the Start-Stop-System* off
when driving through water
9 page 79.
@ Tips
- Determine the depth before driving through
water.
- 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 vehicle to drive
through safely.
-Avoid driving through salt water (corrosion).
Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
... Always use lead-free gasoline 9 page 208,
Fuel supply.
... Never run the tank down all the way to empty.
.,. Never put too much motor oil in your engine
9 page 220, Adding engine oil~-
.,. Never try to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
Driving and the environment
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle 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 mani­
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
CD Note
- Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic converter .
- Do not exceed the correct engine oil level
9page220.
- Do not drive until the fuel tank becomes
completely empty . The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requir­
ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur

Driving and th e en vironm ent
content of the fuel be ing used. Using a differ ­
ent brand of fue l may he lp, or filling the tank
w ith lead-free super grade gasoline.
Diesel particulate filter
Applies to vehicles: with diesel engine
The diesel particulate fi lter fi lters nearly all of
the soot particles out of the exhaust. The fi lter
cleans itself automatically under normal driving
conditions.
If the filter cannot clean itself (for ex­
ample, because you are only driving short distan­
ces), the filter becomes clogged w ith soot and
the

lum inates ¢
page 20.
_& WARNING
-Do not park you r vehicle over flammable
materials such as grass or leaves because
the high temperature of the diese l particu­
late fi lter could start a fire .
-
-Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Placing your vehicle out
of service
If you would like to take your vehicle out of serv­
ice for a longer time, contact your authorized
Audi dealer or qualified repair facility. They will
adv ise you of important measures, such as corro­
sion protection, maintenance and storage proce­
dures. A lso follow the information about the bat­
tery ¢

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels .
Fuel economy, environmental impact, and wear
on your engine, brakes and tires largely depend
on three factors :
-your personal driving style
- operating conditions
196
- technical limitations
If you ant icipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. This sect ion will
give you some tips on how you can help the envi ­
ronment and your pocketbook.
(D 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 vehicle
load and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.. Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are acceler­
ating. If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less. Let the vehicle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage.
.. Try and keep well below your car's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumption, exhaust emissions and engine
noise increase disproportionate ly 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 conditions 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.
~ Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automat ically reduced for
veh icles w ith the Start-Stop-System. It is effi­
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at ra ilroad
crossings and long red lights . Turning the engine
off for just 30-40 seconds saves more fuel than is
b ur ned by sta rting the engine ag ain.
It takes a long t ime for the engine to warm up
fu lly when it is runni ng at idle . Howeve r, wear
and noxio us emiss ions a re espe cially high when
the eng ine is wa rm ing up. So you sho uld d rive
away as soon as you sta rt the engi ne and avoid
r u nning at high rpms whi le the engine is still
warming up .
(D Note
Do not leave engine id ling unatten ded a fter
starting . If warning lights should come on to
indicate im proper operation, they wou ld go
unheeded. Extended id ling a lso produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other proper­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
~ Have your veh icle serviced at regu lar intervals.
By having your veh icle reg ularly serviced by an
Audi dea ler helps to ensure that it runs proper ly
and econom ica lly. The condition of your veh icle
not on ly affects its safety and ability to ho ld its
va lue, it a lso affects
fuel consumption .
Check you r oil each time you fill your tank.
The amount of oil use d i s re lated to e ngine lo ad
a nd speed.
Driving and the envir onment
It is normal for the oil consumption of a new e n­
gine to reach its lowest value after a certain mi le­
age has been dr iven.
Yo u m ust dr ive your ve hicl e abou t 3,0 00 m iles
(S, 000 kilometers) befo re yo u can properly as ­
sess oil consumption .
T h is also ap plies to f ue l cons umption and eng ine
o utput .
CD Note
-Have your ve hicle maintained pro perly and
in acc ordance w ith the se rvice rec ommend a­
ti ons i n your W arra nty
& M ain ten ance book­
let . Lack of proper maintenan ce as we ll as
improper use of the ve hicl e w ill impair the
function of the em ission cont rol system and
co uld lead to damage.
- Do not alte r or remove any component of
the Emission Contro l System unless ap­
proved by the man ufacturer.
- Do not alte r or remove any device, such as
heat shields, switches, ign it ion w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System a nd othe r
im por tan t ve hicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~ Try to avo id driv ing short distances with a cold
eng ine .
T he engine and cata lytic conve rter have to reach
their opt imal
operating temperature to reduce
fuel consumpt io n and noxious emiss ions effec­
tively.
Just afte r starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 m iles per
gallo n (30-40 l/ 100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . Afte r about
2 .5 m iles (4 km), the eng ine is
at its p roper operat ing temperature and fue l
eco nomy has reached a no rma l level. So yo u can
see th at yo u should avoid short trips w heneve r
poss ible. .,.

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
T railer tow ing not only p laces more stress on the
vehicle, it a lso calls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trailer, you must ac­
tivate the trai ler operation mode
¢ page 199, Operating instructions.
Technical requirements
Tr ailer hitch
Use a weight -carrying hitch conforming to the
gross tra iler weight. The h itch must be suitab le
for your vehicle and tra ile r and must be mo unted
securely on the vehicle's chassis at a
technically
sound
location . Use on ly a trailer hitch with a re­
movable ba ll mou nt. Always che ck wit h the t rail­
e r hitch manufac turer to make s ure that you a re
usi ng the co rrect hitch .
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No mod ifica tions should be
made to the vehicle exhaust and brake systems .
Fr om time to time, chec k that all hitch mo un ting
bo lts rem ain securely fastened.
W hen you are not tow ing a trailer,
remove the
tra iler hitch ba ll mount . This prevents the hitch
from ca u sing damage s hou ld your veh icle be
struck from behind

Trailer brakes
If your traile r i s equ ipped with a b raking sys tem,
c h ec k t o be sure that it con forms to a ll regu la ­
tions.
T he tra ile r h ydr aulic bra ke sy stem must not be
directly con nected to the vehicle's hydr aulic
brake sy stem.
Safety chains
Always use safety chains between your vehicle
and the tra iler .
Trailer lights
Trailer lights must meet all regulations. Be sure
to check w it h your Aud i dealer for correct wir ing,
swi tches and relays .
Mirrors
If you are unab le to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear .
A WARNING
--
After remov ing the tra ile r hi tch, do not sto re
i t in yo ur vehicle. In case of sudde n brak ing,
t he hitch could fly fo rwa rd and injure you or
your passengers.
