Energy management
The starting ability is optimized
The energy management system manages the
ele ctrical energy distribu tion and op timi zes the
availability of elec trical energy for starting the
engine .
Whe n a ve hicle wit h a co nven tional e nergy sys
tem is not dr iven for a long time, the ba tte ry is
d rained by equipmen t (fo r example the immobil
izer). In certa in circ umstances, there cou ld may
not be eno ugh energy to start the engine .
Your veh icle i s equ ipped w ith an intellige nt ener
gy managemen t system for distr ibuting electr ic i
ty . Th is significantly improves the starti ng ability
a nd increases the battery life .
T he energy m anagemen t sys tem Is made up of
battery diagno sis, idling current management
and dynamic energy management.
Battery diagnosis
T he batte ry diagnos is determines the ba tte ry
ch arge leve l. The sen sors de te ct the ba tte ry, the
194
batte ry current, an d the batte ry tempera ture.
The c urrent charge leve l and the perfo rmance of
t h e battery are determined based on th is.
Idling current management
The idling cur ren t management decr eases the
energy used wh ile pa rke d. Wi th the eng ine
switched off, it manages the energy dis trib ution
to t he d ifferent e lectr ica l components . Date from
battery diagnos is is ta ken into acco unt for this .
Depend ing on the batte ry charge leve l, elec trical
equipmen t is switched off one item afte r th e o th
e r, to prevent the battery from dra ining and to
r etain the starting ability.
Dynamic energy management
While driv ing , d ynam ic ene rgy man agement dis
t ribu tes the ap propri ate amount of energy to the
e lectrica l equ ipment. It controls the battery
c h arge level so t hat more ene rgy is not use d then
i s be ing generated in order to maintain an opti
mal battery charge level.
(D Tips
- Energy management can not overcome the
laws of p hys ics. Note that the charge level
and length of the battery life a re limited.
- W he n the sta rting ability is endange red, the
(•j indicator light t urns on¢ page 16 .
What you should know
Maintaining the starting ability is the highest
priority .
A lot of st ress is placed on the ba ttery when dr iv
i ng sho rt distances, in t raff ic, and at cold t imes
of the year . A lot of ene rgy is used but little is
generated .
It is also critical when the engine is
not ru nning but e lectr ica l equipment is sw itched
o n. In th is case, energy is used but none is gener
ated.
In sit uat ions like this, energy ma nagement w ill
active ly regu lated the distribution of energy.
Long periods without use
If you do not drive yo ur vehicle for several days or
weeks, e lectr ica l equipment is grad ually scaled ..,.

back or switched off. This reduces energy use and
ensures the vehicle will 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 certa in circum
stances . These convenience functions will be
available aga in once you switch the ignition on
and start the engine.
With the engine switched off
The battery will drain if you use functions such as
listening to the rad io while the engine is switched
off.
The vehicle's ability to start may be impaired by
the energy use, a message w ill appear in the In
fotainment system d isp lay.
The message indicates that the system will
switch off automatically soon. If you would like
to continue using the funct ions, you must start
the eng ine.
With the engine running
Although electrical energy is generated whi le
driving, 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
rarily sca led back or switched off . Heating sys
tems in particu lar require a great deal of energy .
If you notice, for example, that the seat heating*
or rear window defroster is not working, then it
has been tempo rar ily reduced or sw itched off .
These systems are available again as soon as the
ene rgy balance has been restored.
In addition, you may notice that the idle speed
h as slightly increased . That is normal and no
cause for concern. Due to the increased idling
speed , the additional required energy w ill be gen
e rat ed and the battery will be charged.

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 t ires largely depend
on three factors:
-your personal dr iv ing style
- operating conditions
198
- technical limitat ions
If you ant ic ipate what you need to do next and
drive econom ic a lly, you can easily cut yo ur fu el
consump tion by 10-15 percent. This section will
give you some tips on how you can he lp the envi
ronment and your pocketbook .
(D Tips
'
The cons ump tion es tima tes as published by
EN VIRON MENTAL PRO TEC TION AGENCY ( EPA)
and T ransport Canada may not correspond to
your actual consumption on the road, which
will vary depending upon vehicle load and
speed, road and weather conditions, tr ip
l ength, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler
ating.
.. Avo id unnecessary accelerating and brak ing.
Vehicles use the mos t fue l when they a re acceler
ating. I f yo u anticipate what is going to happen
next, you w ill need to b rake less and, thus, accel
erate less. Let the veh icle 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 red uces fue l cons umption,
engine wear, and does not disturb the environ
ment .
Fuel consumpt ion, exhaust emiss ions and engine
noise increase d isproportionately at high speeds .
If you drive at approximate ly three quarte rs of
top speed, fue l consumption will be reduced by
one half. Never drive faster than the posted
speed l imit and weather cond itions 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 automatically reduced for
veh icles with the Start-Stop-System . It is effi
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at railroad
crossings and long red lights. Turning the engine
off for just 30-40 seconds saves more fuel than is
burned by starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially high when
the engine is warm ing up. So you shou ld drive
away as soon as you start the engine and avoid
running at high rpms while the engine is still
warming up .
(D Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling a lso produces
heat, wh ich could resu lt in overheating or oth
er damage to the vehicle or other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
~ Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an
Aud i dea ler helps to ensure that it runs properly
and economica lly. The condition of your vehicle
not only affects its safety and ability to hold its
value, it a lso affects fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load
and speed.
Driving and the environment
It is normal for the oil consumption of a new en
gine to reach its lowest value after a certain mile
age has been driven.
You must drive your veh icle about 3,000 miles
(5,000 kilometers) before you can properly as
sess oil consumption .
T h is also applies to fuel consumption and engine
o ut put .
CD Note
- Have your vehicle maintained properly and
in accordance with the service recommenda
tions in your Warranty
& Maintenance book
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the em ission contro l system and
cou ld lead to damage.
- Do not alter 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 shields, sw itches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips .
~ Try to avoid dr iv ing short distances w ith a co ld
eng ine .
The engine and cata lytic converter have to reach
their optimal operating temperature to reduce
fuel consumpt ion and nox ious em issions effec
t ively.
Just after starting, a co ld engine in a mid-size car
only achieves a fuel economy of 6-8 mi les per
gallon (30-40 l/100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km). After about
2.5 miles (4 km), the eng ine is
at its proper operating temperature and fuel
economy has reached a norma l level. So you can
see that you should avoid short trips whenever
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, p lease remember that
the additional load will affect durability, econo
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trai ler, you must ac
tivate the trailer operat ion mode
c::> page 201, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a
technically
sound
location. Use only a trailer hitch with a re
movable ball mount. Always check with the trail
e r hitch manufacturer to make sure that you are
using the correct 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 modifications should be
made to the vehicle exhaust and brake systems.
From time to time, check that all hitch mounting
bolts remain securely fastened .
When you are not towing a trailer,
remove the
trailer hitch ball mount. This prevents the hitch
from causing damage should your vehicle be
struck from behind
c::> &, .
Trailer mode
Trailer brakes
If your trailer is equipped with a brak ing system,
check to be sure that it conforms to all regula
tions.
T he trailer hydraulic brake system must not be di
rect ly connected to the vehicle's hydraulic b rake
system.
Safety chains
Always use safety chains between your veh icle
and the tra iler.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check with your Aud i dealer for correct wiring,
switches and relays.
Mirrors
If you are unable 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 removing the trailer hitch, do not store
i t in your vehicle. In case of sudden braking,
the hitch could fly forward and injure you or
your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held securely in
place to prevent it from sh ifting forward, back
ward or sideways.
Never allow a passenger to ride in a trailer c::> &.
in Driving instructions on page 203 .
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform
ance is up to the additional load. Make sure that
the cooling system has enough fluid . .,..
201
Trailer mode
Tire pressure
When tow ing a trailer, inflate the tires of your ve
hicle to the cold tire pressure listed under " Full
load" on the label located on the driver's side B
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
Check to make sure both vehicle and trailer lights
are working properly .
Safety chains
Be sure trailer safety cha ins are p roperly connect
ed from the trailer to the hitch on the vehicle.
L eave enough slack in the chains to permit turn
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make su re the vehicle is on a level su rface before
h itching up the trailer and before adjusting the
tongue weight . The vehicle must be in
auto or
comfort driving mode and not raised

· Driving instructions
Driving with a trailer always requires extra care
and consideration .
To obtain the best possible handling of vehicle
and trailer, please note the follow ing:
.,. Do not tow a loaded trailer when your car itself
is not loaded .
.,. Be especially carefu l when passing other
vehicles.
.,. Observe speed lim its .
.,. Do not drive at the maximum permissib le
speed.
.,. Always app ly brakes early .
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car results
i n a h ighly unstab le distribution of weight. If th is
cannot be avoided, dr ive at very low speeds only
to avoid the risk of losing steer ing control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, w hile
k eep ing the traile r as light as possible under the
circumstances. Whenever possible, transfer
some ca rgo to the luggage compartment of the
tow vehicle while observing tongue load require
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be
comes for the driver to contro l the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind cond itions are unfavorab le -particular ly when
going downh ill.
Red uce vehicle speed
immediately if the trailer
shows the slightest sign of swaying .
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 dow n
hill, shift i nto a lower gear to use the engine
