Energy management
Starting ability is optimized
E nergy ma nagement co ntr ols the distribution of elec­
trical energy and thus optimizes the availa bility of elec ­
trical energy for s tarting the engine.
If a vehicle with a convention al ene rgy sys tem is not driven fo r a lo ng
pe riod of time, the battery is d ischarged by idling cu rr ent consumers
(e.g. immo bilizer) . In ce rtain c ircumstances it can result i n there
being insufficien t energy avai lab le to start the engine .
Inte llige nt ene rgy management in your ve hicl e han dles the dist ribu ­
ti on of e lectr ica l energy. Sta rting ability is m arkedly improved a nd
the life of the battery is extended.
B as ically , energy managemen t consis ts of

and dynamic energy management .
Battery diagnosis
Battery d iagnosis continuously determ ines the state of the battery .
Sensors de term ine ba tte ry vo ltage, ba ttery curren t and batte ry
temperature. Th is determines t he current state of charge and the
powe r of th e battery .
Idling current management

Depend
ing on the battery 's state of charge, individual consumers are
gr adu ally t urned o ff to prevent excess ive disch arge of the bat tery an d
t hus maintain start ing capability .
Dynamic energy management
While the vehicle is being dr iven, dynamic energy management
dis tributes the energy gene rated a ccording to the needs o f the in d i­
vidua l compo nen ts. It regulates consumpt io n, so that more electr ica l
energy is no t be ing use d th an is being gene ra ted and ensures an

• But even energy ma nagement cannot negate the limits o f phys ics .
Consider that t he power and life o f a battery are limited.

The engine needs to be run-in during the first 1,000 miles
(1,50 0 km) .
For the first 600 miles (1,000 kilometers):
Do not use fu ll thrott le .
- Do not drive fas ter t han 3/ 4 of the top speed marked on
t h e speedometer.
- Avo id high engine speeds .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
- Spe eds can
gradually be i ncr eas ed to the maxi mu m

General information
T he ope ra ti on of the Ele ctro nic Stabilization P rogr am ( ESP ) is
expanded for operation away from paved roads. In s ituations where
slip or a different ia l lock in g f unct io n is requ ired, t he ESP offroa d
mode can be activated~
page 252. Hill descent control is also avail­
able in the ESP offro ad mode, wh ich a utomatically bra kes the vehicle
and thereby keeps speed consta nt when d ifferent whee l speeds are
de te cted when descend ing a hill~
page 253. Your Audi also has
permanent all-wheel drive in add ition.
However , your Audi is not a pure offroad ve hicle.
It was not bui lt for
dr iv ing un der extreme cond it ions, e.g. for t rips that ar e in th e natur e
of an exped it io n.
Drive only on road s and offroad sections which match the design of
your vehicle and your abilities as a driver. Never take risks!
Before driving offroad
• Check the eng ine oi l level, tire pressure, coolant level, and the
fluid level in the w indshiel d wa sher rese rvoir.
• Stow luggage items and other objects in the luggage compart ­
me nt, and sec ure t hem agains t slid ing ar ound.
After driving offroad
• After tr ips offroad, remove a ny tw igs and other foreign objects
from the gr ill, the underbody an d the whee ls. Pay special attention to
fore ign obje cts (sto nes) wh ich have be come lodge d in the tire tr ead.
• Clean the body and the vehicle unde rside, and ins pect t he vehicle
for possib le dam age. •
Clean dirty w indows, headlamp lenses, rear lights, and lic ense
plates.
• Perform a bra ke check (pa rticul arly afte r travell ing t hrough
wate r).
& WARNING
• Drive especially attentively and plan ahead in difficult road
condit ions and when offroad. E xcessive speed or incorrect maneu­
vers can cau se injurie s and damage to the vehicle .
• Always adapt your speed and driving style to road, offroad,
traffic, and weather condition s. Drive especially slowl y offroad
when your view is restricted.
• Please be aware that in ESP offroad mode, particularly on a
smooth and slippery road, the wheels may have an increased
tendency to spin and the vehicle may break away - danger of skid­ ding!
• Stability i s limited in the ESP offroad mode.
Avoid dama ge to t he e nvir onment and respect nature .

Trailer towing
Driving with a trailer
General information Your Audi was design ed primarily for passenger transpor ­
tation .
If you plan to tow a t rai ler, p lease rem emb er that the add itiona l load
wi ll affect durab ility, economy and performance.
T railer tow ing not on ly p laces mo re s tress on the vehicle, it a lso calls
for more concentrat ion from the driver.
For this reason, a lways follow the ope rating and dr iv ing instr uctions
prov ided and use common sense .
(D Note
If you are going to tow a t ra iler , you must ac tivate the tra ile r ope ra­
tion mode ::::;,
page 180, "Towing a trailer". •
Technical requirements
Trailer hitch
Use a we igh t-car rying hit ch confo rm ing to the g ross tra ile r weig ht.
The hitch must be suitable for your vehicle and tra iler and must be
mou nted secure ly o n th e veh icle's chassis a t a
te chnically sound loca­
tion. Use only a trailer hitch with a removab le ba ll mount. Always
check w ith the tra iler h itch manufacturer to ma ke sure tha t you are
using the correct hitch .
Do not use a bumper hitch .
The hitch must be i nstalled in such a way t hat i t does not interfe re
w ith the impact-absorbing bumper system. No mod ificat ions should

ment Safety first Vehicle operation
be made to the vehicle exhaust and b
rake systems. From time to
time, check that all hitc h mounting bo lts rema in securely fastened.
Whe n you are no t towing a trai ler, remove the trailer hi tch ba ll
mount. This prevents the hitch from caus ing damage should your
vehicle be s truck from behind::::;,& .
Trailer brakes
If your trailer i s eq uipped w ith a b raking system, che ck to be s ure that
it conforms to all regulat ions.
T he tra iler hyd raulic brake system must not be directly connected to
the vehi cle's hydraul ic brake system ::::;, & .
Safety chains
Always use safety chains betwee n your vehicle and t he tra iler .
Trailer lights
Trailer lights must meet all regulat ions. Be sure to check w ith your
au thor ized A udi deale r for co rrect wi ring, switc hes, and re lays.
Mirrors
If you are unab le to see the traff ic beh ind you us ing t he regular
outside m irro rs, then you
must install extended mirro rs. It is impor­
t an t th at yo u
always have cle ar vision to the re a r.
& WARNING
• If a trailer has electrical brakes please note that these brakes
are not activated by the factory-fitted control unit -ri sk of acci ·
dent!
• Afte r removing the trailer hitch, do not store it in your vehicle .
In case of sudden braking, the hitch could fly forward and injure

Lights
T he headl ight settings shou ld be chec ked with the tr ailer attached
before driving off. Check to make sure both vehicle and trailer lights
are wo rking properly.
Safety chains
Be sure tra ile r safety cha ins are p roperly connected from the t rai ler
to the hitch on the vehicle. Leave enough slack in the chains to perm it
tu rning corners . When you install sa fe ty ch ains, ma ke sure they will
not drag on the road when you are driving.
T he chains should cross under the trai ler tongue to prevent it from
dropping in case of separation from the h itch .

If you are goi ng to tow a trai ler , you must activate the trai ler opera­
tion mode =>
page 180, "Towing a trailer". •
Driving instructior,s
Driving with a trailer always requires e xtra care and
consideration.
To obtain the best possib le handling of ve hicle a nd trailer ,
please note the following :
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especia lly careful when pass ing other vehicles .
- Observe speed limi ts.
- Do not drive at the maximum pe rmissible speed.
Controls and equip­
ment Safety first Vehicle operation
- Always apply brakes early.
- Mo
nitor the temperature gauge.
Weight distri but ion
T owing a loaded trailer with an empty car results in a highly unstable
distribution of we ight . If t his cannot be avoided , drive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that the
tow veh icle shou ld be loaded to the extent poss ible and permissib le,
wh ile keeping the tra ile r as lig ht as poss ible unde r the ci rc u mstances.
Whe never possible, transfer some cargo to the luggage compart ­
me nt o f the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more d ifficult it becomes for the driver to
control the r ig . Do not dr ive at the maxim um permiss ible speed .
Reduce your speed eve n more if load, weather or w ind conditions are
unfavorable -particular ly when going downhill.
Reduce vehicle speed
immed iately if the tra ile r shows the slightest
sign of swaying.
Do not tr y to stop the s wayi ng by a ccele rating .
Observe speed lim its. In some areas, speeds for veh icles towing
trailers are lowe r than for regular veh icles .
Always apply brakes early. When driving downhi ll, shift into a lower
gear to use the engine brak ing effect to slow t he ve hicle . Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperatur e
The coo lant temperature gauge=> page 10 must be observed care­
fu lly. If the needle moves close to the upper end of the sca le, reduce
speed immediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the instrument clus ter
starts flash ing
- F- , pull off the road, stop and let the engine idle for
about two m inutes to prevent hea t buil d-up.
