Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimi zes the
availability of electrical energy for starting
the engine.
I f a vehicle w ith a conventional e nergy system
is not driven for a long pe riod of time, the bat­
tery is d isch arged by idling c urrent cons umers
(e .g. immobilizer) . In ce rtain circumstances it
can result in there being i nsu fficient ene rgy
avai lab le to start the engine .
I n tell igent energy m anagement i n your veh i­
cle hand les the d istribu tion of elec trical ener ­
gy . Starting abi lity is marked ly imp roved and
the life of the battery is extended.
B asically , energy m anagement consists o f
battery diagnosis , idling current manage­
ment
and dynamic energy management.
Battery diagnosis
B att ery d iagnosis con tinuously dete rm ines
the st ate of t he battery. Senso rs determ ine
battery vo ltage, batte ry cur rent and battery
tempera ture. This dete rmines the current
state of charge and the powe r of the battery .
Idling current management
Idling current ma nagemen t red uces energy
consum ption wh ile the veh icle is stand ing.
W ith the igni tion swi tched off, i t con tro ls the
energy s upply to the va rious e lectrica l compo­
nents. Data from battery diagnosis is consid­
ered.
D epending on the battery's s ta te of charge,
individua l consumers are gra dually t urned off
to p revent excessive discha rge of the battery
and thus ma inta in start ing capability.
Dynamic energy management
W hile t he vehi cle is being driven, dynamic e n­
ergy ma nagement dis tributes the energy gen ­
erated according to the needs of the indiv idu­
al components.
It r egulates consumption, so
that more electrical energy is not being used
t h an is being generated and ensures an opti­
mal state of c ha rge fo r the battery.
(!) Tips
- But even ene rgy management cann ot
negate the limits of physics. Consider
that the powe r and life of a battery are
limited.
- If start ing ability is threatened, the indi­
cator light

What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short -d istance
driv ing, in city traff ic and during the cold time
o f year. Abundant electrical energy is re­
quired , but on ly a little is ge nerated . It is also
c ritical if the engi ne is not r unning and electri­
ca l components are tu rned on. In this in­
sta nce ene rgy is be ing consumed bu t none is
b eing gene ra ted .
It is in precisely these s ituations t hat yo u will
notice ene rgy management active ly regu lat­
i ng t he d istribu tion of ene rgy.
Vehicle stands for an extended period
If y ou do not drive your vehicle over a period
of several days o r weeks, e lectr ica l compo ­
nen ts a re g radually cut back or sw itched off .
T h is reduces energy consumption and ma in­
ta in s start ing ca pabili ty over a longer pe riod .
Some of the convenience func tion s may not
opera te, such as t he interior ligh ts or the
power seat adjustment. The convenience
funct ions wi ll be available again when yo u
switch on the ignition and start the eng ine . .,.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 197
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system .
Safety chains
Alw ays use saf ety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra iler lights must meet all reg ulations . Be
su re to check with your Audi dea ler fo r cor re ct
wir ing, swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must i nsta ll ext ended mir rors . It is important
t h at you
always have clea r vis ion to the rear .
.8, WARNING
-
Afte r removing the trailer hit ch, do no t
s tore i t in yo ur vehicle . In case of sudden
b raking, the h itch cou ld fly forwar d an d in­
ju re you or yo ur passengers .
Operating instructions
Maximum trailer weight
A tra ile r fo r you r vehicle is limited to a ty pical
cl ass 1 or class 2 tra ile r.
Trailer load distribution
B e sure the loa d in the tr aile r is held secure ly
i n place to p reven t it from shift ing forw ard,
ba ckward or sideways.
Never allow a passenger to ride in a trailer
¢&. in Driving instru ctions on page 198.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is impo rtant that the cooling system's
perfo rmance is up to the additional load .
Make sure that the coo ling syst em has enough
f lui d.
Tire pressure
When towing a trailer , inflate the tires of your
vehicle to t he cold tire pressure listed under .,..

198 Trailer towing
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open) .
Inflate trailer t ires to tra iler and t ire manufac ­
turers' specif ications.
Lights
Check to ma ke s ure bot h ve hicle and trailer
lights are working proper ly.
Safet y chains
Be sure tra ile r safety cha ins are prope rly con­
nected from the trailer to the hi tch on the ve­
h icle. Leave enough s lack in the chains to per­
mit turning corners. When you install safety
chains, make sure they wi ll not drag on the
road when yo u are driving .
The cha ins shou ld cross under the tra ile r
tongue to prevent it from dropping in case o f
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration .
To obtain the best poss ible handling of vehicle
and tra ile r, p lease no te the following:
.. Do not tow a loaded tra ile r when your car it­
self is not loaded.
.,. Be especia lly ca reful whe n passing other
ve­
hicles.
.. Observe speed limits .
.. Do not d rive at the maximum permissible
speed.
.. Always apply brakes early .
.. Monitor the temperature gauge.
W eight distribution
Towing a loaded trai le r with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at
very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is eas ier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent poss ible and permiss i­
ble, while keeping the trailer as light as possi­
b le under the circumstances . Whenever possi- ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tong ue load requ irements and vehicle load ing
considerations.
Speed
T he higher the speed, the mo re d iff icu lt it be­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed . Re ­
duce your speed
even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Red uce vehicle speed
immediatel y if the trail­
er shows the slightest s ign of sway ing.
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
for vehicles towing trai lers are lower than for
regular vehicles .
Always apply brakes early . When driving
down hill , shift into a lower gear to use the en ­
gine braking effect to s low the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperatur e
The coo lant temperat ure gauge ¢ page 10
must be observed carefu lly. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at h igh engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the d isp lay turn on .

A WARNING
Anyone not properly restrained in a mov­
i ng vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not p roperly wea ring the rest raints
p rov ided by A udi.

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
observe a few simple rules.
.. Befo re using the power washer , make sure
yo u have read and understood the WARN­
INGS¢
A in General information on
page 200.
.. Always fo llow the operating instructions for
the power washer .
.. Make sure that the jet o n the spray hose
produces a "fan shaped spray" .
.. Do
not hold the spray nozzle too close to
soft materia ls .
When cleaning the veh icle with a power wash­
er
always follow the operating instructions .
This applies particularly to the
op erating
pr essure
a nd the s pray ing di stance . Keep a
d ista nce from soft materials such as rubber
hoses o r insulat ing ma ter ial as well as sensors
and camera lenses . Do not use a jet which sprays water in a
d
ir ect
stream
or one t hat has a rotating jet .
Water temper ature sho uld not ex ceed 140 °F
(60 °().
A WARNING ~ -
Neve r wash tires with a jet that sprays wa­
ter i n a direct stream. This could cause in ­
vis ib le damage to the t ires and weaken
them, even if the spray is from a re lative ly
l ong distance and for a short time. Dam­
aged and weakened tires can fail and cause
accidents and personal inj ury.
'
([) Note
To avoid damaging your vehicle, a lways
make sure that there is suffic ient d istance
between the spray head and soft materia ls
like rubber hoses, plast ic pa rts and sound­
deaden ing mater ials as w ell as sensors
and camera lenses. Neve r aim t he sp ray
head at the same point for a long time.
This also applies to cleaning headligh ts
and painted bumpers. Remembe r: the
closer the nozzle is to the surface of the
materia l, the greater the stress on the ma ­
terial.
Sensors and camera lenses
- Remove snow with a hand br ush and remove
ice with a de- ic ing spray that does not con­
tain so lvents .
- Clea n the sensors (adaptive cruise control*,
pa rk ing system*) w ith a cleaning so lution
that does not contain so lvents and a soft
cloth .
- The camera lens or the area in front of the
came ra le ns is no rmally cleaned by the
w indshie ld w ipers o r he adlig ht wipers (night
vision system *).
If the lens or the area is ex­
ceptionally di rty, clean the area wit h glass
cleaner and a soft, dry cloth .
(D Note
-If you was h your veh icle with a pres sure
washer,

-make s ure there is enough distance to
sensors in the front and rear bumper,
- do not clean the camera lenses and the
area around them with the pressure
washer.
- Never use warm or hot water to remove
snow or ice from the camera lens. This
could cause the lens to crack .
- Never clean the camera lens with abra ­
s ive prod ucts .
Waxing and Polishing
Wa xing
A good wax coating protects the vehicle paint
to a large extent against the environmental
factors listed under¢
page 200, Washing and
even against slig ht scratches.
You can use a liq uid ca r wax to protect your
paint as soon as one week after your vehicle
has been delivered.
Even if you regularly use a
wax ing process in
automatic ca r washes, we recommend that
you manua lly app ly a coat of wax to give the
pa int extra protection, particularly if water no
longer beads o n the clean paint.
Protect p lastic body pa rts with car wax in the
same way as the vehicle body.
D uring wa rm weather dead insec ts 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.
P olish ing
P olish you r vehicle on ly if the pa int has lost its
shine and the g loss cannot be brought back
with wax.
If the po lish used does not conta in prese rva­
tive compounds , the paint must be waxed af­
terwa rds .

For environmental reasons, Audi fabricates
the b right t rim strips and trim p ieces from
pure chromium-free al uminum .
Dirt and marks on the trim strips shou ld be
removed w it h a
pH-balanced cleaning agent
(do not use a chrome cleane r). Audi dealers
ca rry clea ning products which have been test­
ed fo r use on your vehicle and are not ha rmfu l

• Use a p lastic ice scraper to remove ice from
w indows and mirrors.
• Remove other residue on the windows with
a spray-on glass cleaner.
• Wipe the windows dry with a clean piece of
cloth or kitc hen paper towel.
The best way to remove snow from windows and mirrors is to use a brush. Use a non-abra­
s ive
pla stic ic e scraper -better still, a spray
deicer - to remove
ice from w indows and mir­
ro rs.
Oil, grease or s ilicone residue can be removed
with
gla ss clea ner or s ilicon e re m over . How ­
ever, wax res idue requires the use of a spec ial­
ly formulated so lvent. Please contact your Au­
di dealer for advice on safe products for wax
remova l.
Windows should also be cleaned on the inside at regu la r i nte rvals .

- The windsh ield must not be treated w ith
water-repellent materials. They can in­
crease glare under poo r visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon . In addi­
tion, they can cause the windshield wip­
ers to chatter.
(D Note
- Never use warm or hot water to remove snow and ice from windows and mirro rs .
Th is could cause the glass to crack.
- To prevent damage to t he wires of the
rear defogger, do not place any adhesive
st ickers on the ins ide of the rear window
over the wires.
...

-To he lp prevent d irt from scratching the

you -never back and forth.
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
.,. Wash the whee ls with a sponge o r hose
brush every other week.
.. For deep cleaning afterwards, use only a
dedicated
a ci d-fr ee cast alloy wheel cleaner .
.,. Rub a coat of
liquid w ax onto the r ims every
three month. Be sure to reach and treat all parts of the rim .
To preserve the decorative appearance of the
cast alloy wheels, some special care is neces­
sary . In add it ion to road dirt and salt, brake
dust is also corros ive. If left on for too long,
brake dust ca n cause pitting .
Use only special
acid-free cleaners formulated
for alloy rims . Safe products are available at
your Aud i dealer. Never leave the cleaner on
the r ims longer than spec ified on the label. If
not rinsed off p romptly, the acid co nta ined in
some cleane rs can attac k the th reads on the
wheel bo lts.
Never use abras ive or metal polishing clean­
i n g agents. If the protective coat ing has been
chipped, e.g. by k icked up road dirt, touch it
up as soon as possib le.
