can result in there being insufficient energy
avai lab le to start the engine .
I ntell igent energy management in your vehi­
cle handles the distribution of electrical ener­
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Basically , energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery volta ge, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individua l consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being dr iven , dynamic en­
e rg y management distributes the energy gen­
erated according to the needs of the individu­
a l components. It regulates consumption, so
that more ele ctrical energy is not being used
than is being generated and ensures an opti­ mal state of cha rge for the battery.
{D) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
c> page 22 7,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability .
The battery is seve rely taxed in shor t-distance
driving, in city tra ffic and dur ing the cold time
of year . Abundant electrical energy is re ­
quired, but only a little is generated . It is also
critical if the engine is not running and e lectri­
ca l components are turned on . In this in­
stance energy is being consumed but none is
being generated.
It i s in precisely these situations that you will
notice energy management actively regulat­
ing 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 , e lectr ica l compo­
nents are gradually cut back or sw itched off.
T his reduces energy consumption and main­
ta ins start ing capability over a longer period .
Take into consideration that when you unlock
your vehicle , some conven ience functions ,
s uc h as the inte rior lights or the power seat
adjustment, may not be available. The con­
venience functions will be available again
when you turn on the ignition and start the e ngine .
With the engine turned off
If you listen to the radio, for example, w ith
the engine turned off or use other MMI func ­
tions, the battery is being discharged .
If starting capability is jeopardized due to en­
ergy consumption , the following warning ap­
pears in the MMI display:
Please start engine, otherwise system will
switch off in 3 minutes .
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you w ish to continue using the funct ions, you
have to sta rt the eng ine.

232 Driving o ff road
Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stability Con­
trol (ESC) is expanded for operation away
from paved roads. In situations where slip or a
d ifferential locking function is required, the
ESC offroad mode can be act ivated
c::;, page 219 . Hill descent control is also availa­
ble in the ESC offroad mode, which automati­
cally b rakes the vehicle and thereby keeps
speed constant when diffe rent wheel speeds
a re detected when descending a hill
c::;, page 220. Your Audi also has permanent
a ll-whee l drive in addition.
H oweve r, your Aud i is not a pure off road vehi­
cle .
It was no t built for d riving unde r extreme
conditions, e .g. fo r trips that are in the natu re
of an expedit ion .
Dri ve only on road s and offroad section s
which match the de sign of y our vehicl e and
y ou r abilitie s as a dri ver. Never take risks!
Before driving offroad
- Check the eng ine oil level, ti re p ressu re ,
coolant level , and the fluid level in the w ind­
shield washe r reservo ir.
- Stow luggage items and o ther objects in the
luggage compartment, and secure t hem
against s liding aro und .
After driving offroad
- After trips offroad, remove any twigs and
othe r foreign objects from the grill, the un­
derbody and the wheels. Pay spec ia l atten­
t ion to fo re ign objects (stones) which have
be come lodged in the tire tread.
- Clean t he body a nd the veh icle unders ide,
and in spec t the veh icle for poss ible damage.
- Clean dirty w indows , headlamp lenses , rear
l ights, and li cense plates .
- Perfo rm a brake check (part icularly after
t ravel ling th rough water) .
A WARNING
-Drive especially attentively and plan
a head in d iff icu lt road conditions and
when off road. Excessive speed o r inco r­
rect maneuvers can cause injuries and
damage to the vehicle.
-
- Always adapt your speed and driving
style to road, offroad, t raff ic, and weat h­
er cond itions. Drive e specially slowly off­
ro ad when you r view is res tricted.
- Please be awa re that in ESC off road
mo de, particularly on a smoo th and s lip­
pe ry road, the wheels may have an in­
crease d tendency to sp in and the vehicle
may b reak away - danger of skidding!
- Stabili ty is limited in the ESC off roa d
mode .
@) For the sake of the environment
Avoid damage to t he environmen t an d re­
s pect na tu re .
(D Tips
Only d rive w here it is permitte d and stay
on marked road s and pat hs.
Explanation of some technical terms
The following data refe r to ideal cond itions.

Gradient angle
The number of meters in alt itude ga ined over
a distance of 109.4 yards or 100 meters
(grade) are given as a percentage or degrees.
Information about the gradient the vehicle
can climb under its own power (depends in
part on the road surface and engine power) .
Max imum pe rm itt ed grade : 3 1

Later al angle (slope of vehicle )
Indicates the angle up to which the vehicle
can be driven diagonally or across the fall line ..,.

238 Trailer towing
your vehicle-trai ler combination behaves and
responds.
Backing up is difficult and requires practice.
Backing up with a trailer genera lly requi res
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
mo re room to stop. To compensate for the
trai ler, you will need a larger than norma l
turning 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 trai ler before chang ­
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, you r A ud i may re­
quire more frequent maintenance due to
the extra load
~page 319.
Parking on a slope
Do not pork on a slope with a trailer. If it can­
not be avoided , do so only ofter doing the fol­
lowing:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trai ler wheels .
.. With chocks in p lace, slowly re lease the
brakes until the whee l chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to
P.
When restarting after parking:
.. Apply the foot brake .
.. Start the engine. ..
Move the selector lever to
D.
.. Release the parking brake and s low ly pull
out and away from the wheel chocks .
.. Stop and have someone retrieve 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
wheels, you may have to use more force later to move the lever out of the
P posi­
tion.

directly at locks, or at door or hatch
openings -they can freeze shut.
- Never use sponges designed to remove
insects , or any kitchen scouring sponges
or similar products. They can damage
your paint finish .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never use a dry cloth or
sponge to clean the headlights . Only use
wet cloths or sponges to prevent
scratches . It is best to use soapy water .
@) For the sake of the environment
In the interest of the environment, the ve­
hicle should only be washed in special
wash bays .
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you observ e a few simple rules.
" Before using the power washer , make sure
you have read and understood the WARN­ INGS ~.&.
in General information on
page 239.
" Always follow the operating instructions for
the pow er wash er.
" Make su re that the jet on the spray hose
produces a "fan shaped spr ay" .
" Do
not hold the spray nozzle too close to
soft materials .
When cleaning the vehicle with a power wash­
er
always follow the operating ins truc tions.
T his applies particularly to the
operating
pressure
and the spraying distance. Maintain
a sufficient distance to soft materials such as
rubber hoses and sound/vibration deadening
materials (particularly on the underside of the
engine hood). Do not use a jet which sprays
water in a
direct stream or one that has a ro­
tating
jet.
Water temperature should not exceed 140 °F
(60 °().
Cleaning and protection 241
A WARNING
Never wash tires with a jet that sprays wa­
ter in a direct stream . This could cause in­
visible damage to the tires and weaken
them, even if the spray is from a relatively
long distance and for a short time . Dam­
aged and weakened tires can fail and cause
accidents and personal injury.
(D Note
To avoid damaging your vehicle, always make sure that there is sufficient distance
between the spray head and soft materials
like rubber hoses, plastic parts and sound­
deadening materials. Never aim the spray
head at the same point for a long time.
This also applies to cleaning headlights
and painted bumpers. Remember : the
closer the nozzle is to the surface of the
material, the greater the stress on the ma­
terial.
Waxing and Polishing
Waxing
A good wax coating protects the vehicle paint
to a large extent against the environmental
factors listed under ~
page 239, Washing and
even against slight scratches.
You can use a liquid car wax to protect your
paint as soon as one week after your vehicle
has been delivered.
Even if you regularly use a
waxing process in
automatic car washes, we recommend that
you manually apply a coat of wax to give the paint extra protection, particularly if water no
longer beads on the clean paint .
Protect plastic body parts with car wax in the
same way as the vehicle body .
During warm weather dead insects tend to
collect on the front bumper and on the for ­
ward area of the hood. They are much easier
to remove from paint that is waxed
often . IJ,-
•
•

The MMI control console should be cleaned
with a brush first so that no dirt is trapped be ­
tween the buttons and the housing . We rec­
ommend giv ing the MMI control console a fi­
nal w ipe with a cloth mo istened with water
and d ish washing detergent.
Q;) Note
To prevent damage, make sure that no flu­
id ever gets into the MMI control console .
Aluminum trim
Use only neutr al- pH products to remove spots
and depos its from alum inum surfaces.
C hr ome ca re products and alkaline cleaners
will attack alum in um s urfaces and can dam­
age them ove r time.
& WARNING
Always read and heed a ll WARNINGS and
other information
¢ page 239 .
Fabrics and fabric coverings
Fabrics and fabric coverings (e .g. seats, door
trim panels, etc.) should be cleaned at regu lar
intervals with a vacuum cleaner . Th is removes
surface dirt particles which could become em­ bedded in the fabr ic through use. Steam
cleaners should not be used, because the
steam tends to push the dirt deeper into the
fabric and lock it there.
Norm al cleaning
Generally, we recommend using a soft sponge
or a lint-free microfiber cloth to the clean fab­
ric. Brushes should only be used for carpets
a nd floor mats, since other fabric surfaces
could be harmed by b rushes.
Normal surface sta ins can be cleaned using a
commercia lly available foam cleaner . Spread
the foam on the surface of the fab ric with a
soft sponge and work it in gently. Do not sat u­
r ate the fabric. Then pat the foam dry using
absorbent, dry cloths (e .g. microfiber cloth)
and vacuum it after it has dried comp lete ly.
Cleaning and protec tion 245
Cl ean ing sta in s
Stains caused by beverages (e.g . coffee, fruit
juice, etc.) can be treated with a mild deter ­
gent solution. Apply the detergent sol ution
with a sponge. In the case of stubborn stains, a detergent paste can be applied directly to
the s tain and worked into the fabric . After­
wards, use copious amounts of clean water to
remove the rema ining detergent . Apply the
water with a damp cloth or sponge and pat
the fabric dry with an abso rbent, dry cloth.
Stains from chocolate or makeup should have detergent paste (e .g . ox -gall soap) rubbed in ­
to them . Afterwards, remove the soap with
water (damp sponge).
Alcohol can be used to treat stains from
grease, o il, lipstick or a ballpoint pen . Melted
grease or dye must be patted off using ab­
sorbent mater ial. It may be necessa ry to re­
treat the areas with detergent paste and wa­
te r.
In the case of general soiling of the uphols­
tery and cover material, we recommend hir ing
a specia list that has the eq uipment to clean
the seat cove rs and othe r fabr ic surfaces by
shampooing and spray extraction.

• Dab at the stain . Start at the outside and
work inwards .
• Once the stain is no longer visible, use a
soft dry cloth or t issue to soak up the mois­
ture.
Do not use leather cleaning products on Al­
cantara.
You may use a suitable shampoo for removing
dust and dirt .
Dust and gr it in the pores and seams can
scratch and damage the surface. If the car is
l eft standing in the sun for long periods, the
A lcantara should be protected against direct
sunlight to prevent it from fading. Slight color
variations will deve lop in normal use and are
not an indication of material deterioration .
- Never use chemical solvents (e.g . lighter
fluid, turpentine), waxes, shoe polish or
s imilar products on Alcantara ® surfaces .
- To avoid damage, have stubborn stains
removed by a commerc ial cleaning spe­
cia list.
- Do not use br ushes, stiff sponges or sim­
i larly abrasive cleaning aids.
Safety belts
Only well-maintained safety belts work relia ­
bly when needed.
• Keep be lts clean.
• For cleaning, use a mild soap and water sol­
ution. Let be lts dry thoroughly and away
from direct sunlight.
• Do not allow inertia reel safety belts to re­
tract before they are completely dry.
• Check the condition of your safety belts
reg­
ularly.
Heavily soiled safety belts may not retract
properly .
A WARNING
Damaged safety belts can b reak in a crash . -
Anything that might damage your safety
be lts could mean that you and your pas­
sengers would not be adequately pro­
tected in an accident.
- Safety belt performance depends on cor­
rect insta llation. Never remove be lts
from the veh icle to clean them .
- Do not use chemical clean ing agents,
bleach or dyes. They have corrosive prop­
erties which weaken the webb ing.
- When clean ing your safety belts, inspect
them for damage . If you discover dam­
age, see your authorized Audi dealer .
- Always read and heed all WARNINGS and
other information ¢

' Engine compartment
Be especially careful when cleaning the en­
gine comportment.
Alwa ys switch off the ign ition before clean ­
i ng the engine¢ .&, .
Plenum panel
Remove leaves from the plenum panel in front
of the windshield under the engine hood . This
prevents the water drain holes from becoming
blocked, and it prevents debris from enter ing
the vehicle interior through the heating and
ventilat ion ducts.
Cor rosion protection
The engine compartment and transmission
have been corrosion -protected at the factory .
Good anti- corrosion treatment is very impor­
tant, particu larly in the w inter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and plenum panel
shou ld be thoroughly cleaned at the end of
winter and retreated to prevent salt damage.
At the same time, the underside of the vehicle
should be washed as well. ..,_

252 Fuel supply and filling your fuel tank
Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fue l filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No. 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter. It is also norma l when whitish-blue
smoke comes out of the tailpipe after starting
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine idle unnecessari ­
ly after a cold start. Driving off slowly will
shorten the warm-up period.
A WARNING
- Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in ser ious engine damage and per­
sonal injur y.
- Never use fuel line anti-freeze offered for
gasoline engines.
(D Note
- Your Diesel engine has been specifically designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasoline. The
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
cause expensive engine repairs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel sho uld get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not allow D iesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.

proper ly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
A WARNING
-Under normal operating conditions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other conta iners used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision .
If you must
transport fuel to use for your lawn mower,
snow b lower, etc., be very careful and al ­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the ..,.

container meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tank
