-Always keep the compartment above the
rearview mirror closed while driving to re­
duce the risk of injury in the event of sudden
braking maneuvers or a collision .
CJ) Note
Objects located on the rear shelf that rub
against the rear window could damage the
heating wires for the rear window defogger.
@ Tips
-A vent slot is located between the shelf and
the rear window. Do not block the vent with
any items you may place on the rear window
shelf.
- Do not place bulky items on the rear window
shelf as they could restrict or block the driv­
er's vision in the rear view mirror .
Roof rack
Description and mounting locations
Additional cargo can be carried with a roof lug­
gage rock .
Fig. 64 Roof rack attachment points
• Always read and follow the instructions provid­
ed by the roof rack manufacturer when instal­
ling the roof rack system .
If luggage or cargo is to be carried on the roof,
you must observe the following :
- Only use roof racks approved for your vehicle.
These approved roof racks are the basis for a complete roof rack system. Additional attach­
ments or carrier systems are needed to trans­
port luggage and sports equipment . We recom-
Seats and storage
mend using roof racks from the Audi original
accessories program.
- When installing the roof rack, make sure it is
only mounted on the designated locations on
the roof
c::> fig. 64.
- We recommend that you keep the installation
instructions for your roof rack system together
with your Owner's literature in the vehicle.
When should the roof rack be removed?
-Before going through an automatic car wash (it
is best to ask the car wash operator for advice).
- When not in use, to reduce fuel consumption,
wind noise and to guard against theft .
_& WARNING ,_____ -
- Use of an unapproved roof rack or incorrect
mounting of an approved roof rack can
cause the roof rack or the items attached to it to fall off the roof onto the road.
- Objects falling from the roof of a vehicle can
cause a crash and personal injury.
- Only mount the roof rack on the designated
locations on the roof
c::> fig . 64.
- The roof rack system must be installed ex­
actly according to the instructions provided.
- When driving with a roof rack system,
changes to the center of gravity and wind re­
sistance can change the vehicle handling
and lead to a co llision. Always adapt your
driving and your speed to the current condi­
tions.
(D Note
- Your vehicle warranty does not cover any
damages to the vehicle caused by using roof
racks or mounting structures not approved
by Audi for your vehicle. The same applies to
damage resulting from incorrect roof rack
installation.
- Always check the roof rack mountings and
hardware before each trip and during a trip
to make sure everything is securely tight­
ened. If necessary, retighten the mountings
and check the entire system from time to
time. ..,.

Warm and cold Climate control system
Description
The climate control system warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It
is the most effect ive when the windows and sun­
roof are closed. If there is a build-up of heat in ­
side the vehicle, ventilation can help to speed up
the cooling process.
I n all heating mode functions except
defrost, the
b lower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensat ion from the cooling system can drip
and form a puddle of water unde r the vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filte r removes pollutants such as
dust and pollen from the ai r.
The air pollutants filter must be changed at the
intervals specified in your Warranty & Mainte­
nance booklet, so that the a ir condit ioner can
properly work.
If you drive your vehicle in an area with high air
pollution, the filter may need to be changed
more frequently than spec ified in your Audi Wa r­
ranty
& Maintenance booklet. If in doubt, ask
your authorized Audi Service Adv isor for advice.
Key coded settings
The climate control settings are automat ically
stored and assigned to the remote control key
that is in use.
_&. WARNING
Reduced visibility is dangerous and can cause
accidents .
- For safe dr iv ing it is very important that all
windows be free of ice, snow and condensa­
tion .
Warm and cold
-Comp letely familiarize yourse lf with the
proper use and funct ion of the heating and
ventilation system and especially how to de­
fog and defrost the windows.
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshie ld first, using the heat­
ing and vent ilation system. The washer solu­
tion may freeze on the windsh ield and re­
duce visibility.
(D Note
- If you suspect that the air conditioner has been damaged, sw itch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repairs to the Audi air conditioner require
special techn ical knowledge and spec ial
tools. Contact an authorized Aud i dealer for
assistance.
@ For the sake of the environment
By reducing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
- Keep the air intake slots (in front of the
w indshield) free from ice, snow and debris
in order to main tain the proper function of
the climate control system.
- T he energy management system may switch
the seat heating * or rear window defroster
off temporarily. These systems are avai lab le
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of cloth ing on
the luggage compartment cover, ensure
that the openings are not covered.

Smart Technology
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati­
cally when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
I n vehicles with dynamic steering*, ESC also
he lps to stabilize the steering in critical situa­
tions .
Selective wheel torque control
Select ive wheel torque control is used when driv­
ing on c urves . The front wheel on the inside of
the curve or both whee ls on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves . Th e applica­
b le system may not activate when driving in wet
or snowy conditions .
A WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
c ially important on slippery or wet roads. If
the systems beg in acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic
Switching on/off
conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when dr iving
too fast, especially through curves and on
slippery or wet roads, and when driv ing too
close to vehicles up ahead. The ESC and its
integ rated systems cannot always prevent
collisio ns -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four wheels are equ ipped w ith identical
t ires. Different tire s izes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­ scribed are working.
ESC turns on automatically when you start the engine .
Fig. 152 Version A : lower center console,~ OFF button
The ESC is designed to function in levels. Depend­
ing on the level that is selected, the stabilization
function of the ESC is limited or switched off. The

Smart Technolog y
(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
Qpage 16.
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 co ld time of
year . Ab undant electrical energy is required, but
only a little is generated. It is also critical if the
engine is not runn ing and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situat ions that you wi ll no­
tice energy management actively regulating the
d istr ibut io n of energy.
Vehicle s tand s for an exte nded p eriod
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l 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
ven ience funct ions may not operate, such as the
interior lights or the powe r seat adjustment. The
conven ience functions will be ava ilable again
when you sw itch on the ign it io n and start the en­
g ine.
With th e engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI funct ions,
the battery is being discha rged .
If starting capability is jeopardized due to energy
consumption, a message appears in the MMI dis­ p lay . The message ind icates that the system will
be sw itched off automat ica lly in a moment. If
you wish to cont inue using the functions , you
have to start the engine .
176 With the en
gine running
Although elec trical energy is generated when the
vehicle is being d riven, the battery can become
discharged . This happens mostly when litt le en­
ergy is being generated and a great deal con­
sumed and the battery's state of charge is not
optimal.
T o bring the energy ba lance back into equilibri­
u m, consumers whic h req uire especially large
amounts of energy are temporari ly cut back or
switched off. Heating systems in part icular re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* o r the heated rear
window are not heating, they have been tempo­
r ari ly cut back o r switched off . Th ese systems w ill
be ava ilable again as soon as the ene rgy ba lance
has been res tored.
You w ill also notice that engine id le speed has
been increased slightly . Thi s is normal and not a
ca use for concer n. By increasing eng ine idle
speed the addi tional energy required is gene rated
and the battery is charged.

Driving and th e environment
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rai lroad
crossings, or at traff ic lights that have long waits
on red. Turning the eng ine off for just 30-40 sec­
onds saves more fuel than is burned 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 nox ious em issions are especially h igh when
the engine is warm ing up. So you should dr ive
away as soon as you start the engine and avoid running at high rpms while the engine is still
warming up.
{[) Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended id ling a lso produces
heat, wh ich co uld resu lt in overheating or ot h­
er damage to the vehicle or other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
~ Have you r vehicle se rv iced at regular i nte rva ls.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
r u ns p roperly and economically. The condition of
your veh icle not only affe cts its safety and ability
to hold its va lue, i t also affects
fue l con sump ­
tion.
Ch eck your oil each tim e you fill your tank .
The amount of oil used is related to engine load
and speed .
It is normal for the oil consumption of a new en­
g ine 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 ki lometers) before you can properly as­
sess o il consumption .
This a lso applies to fuel consumption and engine
output .
180
(D Note
-Have your veh icle ma intained 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 emission control 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, ignit ion wires,
valves, which a re des igned to p rotect your
vehicle's Emission Control System and other
impo rtant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~ Tr y to avoid dr iv ing sho rt distances w ith a co ld
eng ine .
The eng ine and cata lytic converter have to reach
their opt imal
op erat ing temperature to reduce
fuel consumpt io n and noxious em issions effec­
tive ly.
Just after starting, a co ld eng ine in a mid -s ize car
o nly achieves a fuel economy of 6-8 m iles per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy climbs to 12 mpg ( 20 l/100
k m). After about
2.5 mi les ( 4 km) , the eng ine is
at i ts p roper operating tempera ture and fuel
economy has reached a normal level. So you can
see that yo u should avo id short trips whenever
poss ib le.
