The all-wheel drive concept is designed for high
engine power. Your ve hicle is exceptionally pow
erful and has excellent driving characterist ics
both under norma l dr iving condit ions and on
snow and ice. Always read and follow safety pre
cautions ¢.&. .
Winter tires
When driving in the w inter, your vehicle with a ll
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be adv isa
b le to mount w inter t ires (or all-season tires) for
i mproved driveab ility and brak ing : these tires
must be mounted on
all four wheel s. See a lso
¢ page 249, Winter tires.
Tire chains
Where tire chains are manda tory on certain
roads, this normally also applies to vehicles w ith
a ll-wheel drive¢ page 249 , Snow chains.
Replacing wheel s/tires
Veh icles with all -whee l dr ive must always have
tires of the same s ize. A lso avo id tires with differ
ent tread depths . For detai ls see page
¢ page 241, New tires or wheels.
A WARNING
Always adjust you r driving to road and t raff ic
conditions. Do not let the extra safety affo rd
ed by all-wheel drive te mpt you into tak ing
extra risks.
- Alt hough the all-whee l dr ive is very effec
t ive, always remember th at br akin g ca pac ity
is limited by tire traction. Yo u should t here
fore not d rive at excess ive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be caref ul not to drive
too fast because the front wheels co uld be
gin to slide on top of the water (a quaplan
ing). If this shou ld occu r, you w ill have no
warning from a sudden increase in eng ine
speed as with a front -whee l dr ive vehicle.
Intellig ent Technology
Always d rive at speeds which are suited to
the road conditions -risk of c rash.
Energy management
Starting ability is optimized
E nergy management controls the distribution of
electrical energy and thus optimizes the availa
bility of electrical energy for starting the engine .
If a vehicle with a conventional energy system is
not dr iven fo r a long pe riod of time, the ba ttery is
discharged by id ling curre nt cons umers (e.g. im
mobili ze r). In ce rtain circumstances i t can resu lt
i n t he re being insuffi cient energy av ailabl e to
st ar t the eng ine.
Intellige nt ene rgy manageme nt in yo ur vehicle
hand les the d ist ribution of electrical e nergy.
St art ing abil ity is m arkedly improved and the life
of the ba ttery is ex tende d.
Bas ica lly, energy management co nsists of
bat
tery diagnosis , idling current management
and
dynami c energy management .
Battery diagnosis
Battery d iagnosis continuously determ ines the
state of the battery . Sensors de termine battery
vo ltage, battery curren t and batte ry tempera
tu re . This determines t he cur rent state of c harge
and the power of t he ba ttery.
Idling current management
Idli ng cur rent management reduces energy con
s u mption wh ile the vehicle is standing . With the
ignition switched off , it contro ls the energy sup
ply to the vario us elec trical componen ts. Data
fr om b attery diagnosis is co nsidere d.
Depend ing on the ba tte ry's s ta te of charge, indi
v idual consumers are gradually turned off to pre
ven t ex cess ive disc ha rge of t he battery and thus

Dynamic energy management
While the vehicle is being driven, dynam ic e nergy
manageme nt dis trib utes the energy generated
according to the needs of the ind ividual compo-
nents.

Intelligent Technology
electrical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
(D Tips
- But even energy management cannot neg ate the limits of physics . Consider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica
tor light (•) appears
r=:; page 33.
What you should know
The highest priority is given to maintaining start
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrical energy is required, but only a little is generated. It is also critical if the
engine is not running and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situations that you will no
tice energy management actively regulating the
distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca pability over a longer period. Some of the con
venience functions may not operate, such as the interior lights or the power seat adjustment . The
convenience functions will be available again
when you switch on the ignition and start the en
gine.
With the engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI" functions,
the battery is being discharged .
If starting capability is jeopardized due to energy
consumption, a message appears in the radio or MMI* display . The message indicates that the
system will be switched off automat ical ly in a
196
moment. If you wish to continue using the func
tions, you have to start the engine .
With the engine running
Although electrical energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en
ergy is being generated and a great deal con
sumed and the battery's state of charge is not
optimal.
To bring the energy balance back into equilibri
um, consumers which require especially large
amounts of energy are temporarily cut back or
switched off. Heating systems in particular re
quire a great deal of energy. If you notice, for ex
ample, that the heated seats* or the heated rear
window are not heating, they have been tempo
rarily cut back or switched off . These systems will
be available again as soon as the energy balance
has been restored.
You will also notice that engine idle speed has
been increased slightly . This is normal and not a
cause for concern. By increasing engine idle
speed the additional energy required is generat
ed and the battery is 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 kilometer s):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1 ,000 to 1 ,500
kilometers):
"' Speeds can gradually be increased to the maxi
mum pe rm issib le road or engine speed .
During and after break-in pe riod
"' Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any c ircumstances.
"'U pshift into the next higher gear

During the first few hours of driving, the eng ine's
internal friction is higher than later when all the

Driving and the envir onment
New tires
If your vehicle is runn ing on new tires, d rive very
car efu lly fo r the firs t 35 0 miles (500 kilometers)
a ft er fit ting.
WARNING
New tires tend to be slippe ry and must a lso
be "bro ken-in". Be sure to remembe r th is dur
i ng the fi rst 350 m iles (500 kilometers).
Brake gent ly. Avoid following closely behind
other vehicles or other s ituations that m ight
r equire sudden, hard b raking.
Catalytic converter
Applies to vehicles: wit h gasoli ne e ngi ne
It is very important that your emission control
system (catalytic converter) is functioning prop
erly to ensure that your vehicle is running in an
environmen tally sound manner.
"' Always use lead-free gasoli ne c> page 212,
Gasoline .
"' Never run t he tank down all the way to empty.
"'N ever put too much mo to r oil in yo ur eng ine
c=> page 2 24, Adding engine oil 'l:::r. .
"' Never try to push- or tow-start your veh icle.
T he cat alyt ic co nverter is an efficie nt "cle an-up"
device built into the exhau st sys tem o f the ve hi
cl e. T he catalyt ic converte r burns many of the
po llutants in the exhaust gas before they are re

prope r fu nct ion ing of the engine.
A WARNING
=
The temperat ure o f the exhaust system is
hi gh, both when driv ing and after stopping
the eng ine.
-
- Never touch the exhaus t tail pipes once they
have become hot. This cou ld res ult in burns.
- Do not park or operate the vehicle in a reas
where the hot exhaust system may come in
contact w ith dry g rass, brush, fuel sp ill o r
other mate rial wh ich can ca use a fire.
197
Driving and th e en vironm ent
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani
fold, exhaust pipes, catalytic converter or heat sh ields . During dr iv ing, the substance
used for undercoating could overheat and
cause a fire .
{U) Note
-Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic co nverter .
- Do not exceed the correct engine oil level
c:>page224 .
-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 converte r to overheat.
- Do not turn off the ignition while the vehicle
. . 1s moving.
- Do not continue to operate your vehicle un
der these cond itions, as otherwise fuel can
r each the catalytic converte r. This could re
su lt in overheating of the converter, requir
i ng its replacement .
- To assure efficient operation of the Emis
s ion 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 em ission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op
erat ing properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op
erat ing states . This depends on the su lfur
content of the fuel be ing used. Using a differ
ent brand of fue l may he lp, or filling the tank
with lead-free super grade gasoline.
198
Diesel particulate filter
Applies to vehicles: with diesel engine
The diese l particulate filter filters near ly all of
the soot particles out of th e exhaust. The filter
cleans itself automat ically under normal d riving
conditions. If the filter cannot clean itself (for ex
ample, because you are only driving shor t distan
ces), the filter becomes clogged with soot and
the
II symbol for the diesel part iculate filter il
luminates

&_ WARNING
-Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel particu
late filter could start a fire.
-
- Do not apply an underbody protectant in the
exhaust system area or a fire could start.
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 no t bottom out and ge t damaged.
This is espec ially true for vehicles with low-s lung
chassis (sports chassis)* and fully loaded
vehicles.
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
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cu t your fuel

(D Tips
T he consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre
spond to your act ual 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 accelerating 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
b le -for example when you see that the next traf
fic light is red .
Avoid full throttle
Driving a t moderate speeds saves fuel and im
proves your mileage .
.. Try and keep well be low your car's max imum
speed.
Accelerating gent ly reduces f uel consumption,
engine wear, and does not disturb the environ
ment.
F ue l cons umption, exha ust emissions and engine
noise increase d isproportionately at high speeds.
If yo u drive at approximately three quarters of
top speed, fuel consumpt ion w ill be reduced by
one ha lf. Never drive faster than the posted
speed limit and weather conditions perm it .
Driving and the envir onment
Reducing unnecessary idling
Even when your car is just idling it burns up fuel .
.. Shut the eng ine off when you are not driving
the vehicle.
.. Do not warm up t he vehicle by lett ing the en-
gine run at idle .
The idling phase is automatically reduced for
vehicles with the Start-Stop-System*. It is effi c ient to sw itch off the engine in veh icles without
the Start-Stop-System* when stopped at ra ilroad
c ross ings and long red lights . T urning the engine
off fo r just 30-40 seconds saves mo re fue l th an is
bur ned by s tarti ng the eng ine again .
It takes a long time for the eng ine to warm up
fully when it is ru nning at id le. However, wea r
and noxious emissions are especially high w hen
t h e engine is war ming up. So yo u should dr ive
aw ay as soon as you star t the eng ine and avoid
runn ing at high rpms w hile the engine is sti ll
warming up .
(D Note
Do not leave eng ine idling unatt ended after
start ing. If wa rning lights sho uld come on to
i ndicate impro per operation, they would go
u nheeded. Extended idling also prod uces
heat, which could result in overheating or
other damage to the vehicle o r othe r proper
ty .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
.. Have your vehicle serviced at regular interva ls.
By hav ing your vehicle regular ly serv ice d by an
authorized Aud i dea ler helps to ensure that it
runs properly and economically . T he cond ition o f
yo ur vehicle not on ly affects its safety and ability
to hold its value , it also affects
fuel consump
tion .
Check your oil each time you fill your tank.
T he amou nt o f oil used is related to engine load
and speed. .,,.
199
Driving and th e en vironm ent
It is normal for the oil consumption o f a new en
gine to reach its lowest value after a certain mile
age has been driven .
You must drive yo ur vehicle about 3,000 miles
(5,000 kilometers) before you can properly as
sess oi l consumption.
This a lso applies to fuel consumption and engine
outpu t.
@ Note
- Have yo ur vehicle maintained properly and
i n accordance with the serv ice recommenda
tions in yo ur Warranty
& Maintenance book
l et. Lack of proper maintenance as well as
improper use of the vehicle will impair the
funct ion of the emission control system and
could lead to damage.
- Do not a lter 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 shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Cont rol System and other
i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.,. Try to avoid driving short distances with a cold
engine.
The engine and catalytic converter have to reach
their optimal
oper ating temp eratur e to reduce
fuel consumption and noxious emissions effec tively .
Just after starting, a co ld engine in a mid-size car
only achieves a fue l economy of 6-8 miles 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), the engine is
at its proper operating temperature and fuel
economy has reached a normal level. So you can
see that you sho uld avoid short t rips whenever
possible.
200
The out side t empe rature is also critica l in this re
gard . Your car consumes more fuel in the winter
than in the summer.

General information
The operation of the Electronic Stabilization Con
trol (ESC) is expanded for operation away from paved roads. In situations where slip or a differ
ential locking fun ction is required , the offroad
mode can be activated ¢
page 190. Your Audi al
so has permanent all-wheel drive in addition .
However, your Audi is not a pure offroad vehicle.
It was not built for driving under extreme condi
tions, e.g. for tr ips that are in the nature of an
expedition .
Drive only on roads and offroad sections which
match the design of your vehicle and your abili
ties as a driver. Never take risks!
Before driving offroad
-Check the engine oi l level, tire pressure, coo l
ant level, and the fluid level in the windshield
washer reservo ir.
- Stow luggage items and other objects in the
luggage compartment, and secure them
against sliding around.
After driving offroad
-After trips offroad, remove any twigs and other
foreign objects from the gri ll, the underbody
and the wheels. Pay special attention to foreign
objects (stones) which have become lodged in
the tire tread.
- Clean the body and the vehicle underside, and
inspect the vehicle for possible damage.
- Clean dirty windows, headlamp lenses, rear
lights, and license plates.
- Perform a brake check (particularly after travel
ling through water).
A WARNING
-Drive especially attentively and plan ahead
in difficult road condit ions and when off
road. Excessive speed or incorrect maneu
vers can cause injuries and damage to the
vehicle .
Offroad driving
-Always adapt your speed and driving style to
road, offroad, traffic, and weather condi
tions. Drive especially slowly offroad when
your view is restricted.
- Please be aware that in offroad mode, par
ticularly on a smooth and slippery road, the
wheels may have an increased tendency to spin and the vehicle may break away - dan
ger of skidd ing!
- Stability is lim ited in the offroad mode .

Driving tips
On poor rood ond offroad, there is always only
one motto: Plan ahead and drive slowly!
Pl ease observe the following when driv ing away
from paved roads:
.,. Drive only on roads and off road sections which
ma tch the des ign of your vehicle and yo ur abili
ties as a driver . Neve r take risks!
... Drive slowly and p lan ahead!
... Take into consideratio n the
ground clearan ce
of your veh icle.
.,. Activate the
offro ad mode Q page 190 as need
ed .
.,. Use the
hill desc ent a ssis t Q page 192 when
driv ing down steep sections on hills .
Unpaved roads and offroad
Drive s low ly on unfam iliar roads and unknown
offroad sections, and look out for unexpected ob
stacles (e .g. potholes, rocks, tree stumps, etc .) .
To prevent the veh icle from bottoming and avoid
damage to the underbody, you should d rive
stra ight across severe bumps in the ground with
only one side of the vehicle so that only two of
your wheels cross the b umps.
Drive briskly through sandy or marshy offroad
sections and do not stop , if at all possible .
Driving through water
Note the following to avoid vehicle damage when
driving throug h water, fo r example on flooded
roads:
- T he wate r must no t be any higher than the bot-
tom of the vehicle body .
- Do no t drive fas ter than wa lking spee d.
Driving on a slope
If you ever find yo urself not able to cl imb a s lope,
do not try to turn around, d rive back down in
re
verse .
Otherw ise, you run the risk of tipping over.
202 If the vehicle thre
atens to tip o ver when dr iving
across a slope, you must immediately stee r
downhill in the direction of the slope.
Do no t pa rk you r vehi cle on steep s lopes or
grades .
To reduce the risk of tipping over, drive on slopes
i n the d irect io n of the downwa rd slope (fa ll line) -
not cros swi se .
& WARNING
After driving thro ugh water, mud, slush, etc.,
the brakes may be slow to take effect beca use
of wet brake rotors and pads. Dry the brakes
f irst by braking carefu lly to restore the full
braking effect .
(D Note
- Vehicle components such as the engine,
transmiss ion, suspension or electrical sys
tem can be seve rely damaged by driving
throug h water.
-Always switch off the Start-Stop-System *
when driving through water Qpage 93.
(D Tips
-Check the de pth of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or
switch the engine of f whe n driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep fo r your vehicle to drive
t h roug h safe ly.
-Avoid driv ing through salt water beca use it
can cause corrosion.
