-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. ..,.

-Have your veh icle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
book let.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used . Using a differ­
ent brand of fuel may help, or filling the tank
w ith lead-free super grade gasoline.
Shutting down vehicle
If you wou ld like your vehicle to remain inopera­
tive for a longer period of time, contact an Audi
or other specialized dealer. T hey can advise you
on necessary precautions e.g. corrosion preven­
tion, maintenance and storage. Pay attention to
additional information concerning the battery. Refer to
c:;, page 196.
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.
Fu el economy, environmental impact , and wear
on your engine, brakes and tires largely depend
on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fue l
consumption by 10-15 percent. This sect ion will
give you some tips on how you can help the envi­
ronment and your pocketbook .
Driving and the environment
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport 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 .
.. Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are acceler­
ating. If you anticipate what is going to happen next, you will need to brake 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 reduces fue l consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumpt ion, exhaust emiss ions and engine
noise increase disproportionately at high speeds.
If you drive at approximate ly three quarters of
top speed, fue l consump tion 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 eng ine off when you are not driving
the vehicle.
.. Do not warm up the vehicle by letting the en-
gine run at idle .

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 .

(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.
The
outside temperature is also cr itical in th is re­
gard. Your car cons umes more fuel in the winter
than in the summer.

Checking and F ill in g
Using the proper engine o il is important for the
functionality and service life of the engine. Your
engine was factory-fi lled w ith a high-quality o il
which can usually be used throughout the ent ire
year.
@) Note
Your L imited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended ma intenance and use
requ irements as set forth in the Audi Ow ne r's
Manual and Wa rranty
& Ma intenance booklet .
- Use only a high quality eng ine oil t hat ex-
pressly comp lies w ith the Audi o il quality
standard specified for your vehicle's e ngine .
Using a ny other oil can cause se rious engine
damage.
- Do not mix any lubricants o r othe r addit ives
i nto the engine oil. Doing so can cause en ­
g ine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
y o ur eng ine requires, you m ay add a total of
no more than 0.5 quart/li ter o f a h igh-quali ty
"synthet ic"oil that meets the fo llowing speci ­
fications .
- V ehicles wi th gasoline engine: AC EA A3 o r
API SM with a viscosity grade of SAE 0W- 30,
SAE SW -30 or SAE SW-40 .

www .aud iusa.com or www .aud icanada .ca .
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubrication and cool­
i n g of in ternal engine components, all interna l
combustion engines consume a certai n amount
of oil. O il consumption var ies from engine to en­
g ine and may change significant ly ove r the life of
190
the engine. Typically, eng ines with a specif ied
break-in period (see
¢ page 177) consume mo re
o il dur ing the b reak -in per iod than they consume
after oil consumption has stabili zed.
U nder normal cond itions , the rate of oi l con ­
s u mption depends on t he qu ality and viscosity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem ­
perature and road condit ions. Further factors are
the amount of o il di lution from water condensa ­
tion or fuel residue and the ox idat ion level of the
o il. As any engine is s ubject to wear as mileage
builds up, t he oil consump tion may inc rease ove r
t ime unt il rep lacement of wo rn component s may
become necessary.
With a ll these va riab les coming into p lay, no
sta ndard ra te of oil consumpt ion can be estab­
li shed or spe cified . There i s no altern ative to reg­
u la r and freq uent checking o f the oil leve l, see
Note .
If the yellow e ngine oi l leve l wa rning symbo l El
in the instr ument cluster lights up, yo u should
chec k the o il level as soon as possible
¢ page 191 . Top off the oil at your ear liest con ­
venience ¢page 191.
A WARNING
Before you chec k anything in the eng ine com­
partment, always read and heed a ll WARN­
INGS¢ .&. in Working in the engine compart­
ment on page 187 .
@ Note
Driving with an insufficient oi l level is likely to
cause severe damage to the engine.
(D Tips
- The oil pressu re warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going on a long trip.
- If you have the impression yo ur engine con­
sumes excessive amounts of oil, we r ecom-
mend that yo u consult an au tho rized Audi .,.

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of
vehicle control and increase the risk of an accident. Read
and follow the important
safety precautions in
¢ page 208, Tires and vehicle
load limits.
-The tire must flex more if the tire pressure is too low or if the vehicle speed or load are
too high. This heats the tire up too much. This increases the
risk of an accident because it
can cause the tire to burst and result in loss of vehicle con­
trol.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side B­
pillar, always follow the specifica­
tion on the B-pillar label
¢ page 206, fig . 171 .
Wheels
-Incorrect tire pressure increas­
es tire wear and has a negative
effect on driving and braking behavior, which increases the
risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a nor­
mal load¢
page 207 or for a
full load when the vehicle is
partially loaded.
Make sure that the tire designa­
tion on your tire matches the des ­
ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­
mended tire pressures in cold
tires according to the load and
the size of the tires installed.

yourself, because this increases the risk of
an acc ident.
Winter tires
W inter tires sign ificantly improve t he vehicle's
h andling when drivi ng in winter condit ions. Be­
cause of the ir construction (width, compound,
tread pattern), summer t ires p rov ide less t ract ion
on ice and snow.
.. Use w in ter t ires on all four wheels.
.. Only use winter tires that are approved for your
vehicle .
" Please note that the maximum permitted
speed may be lower w it h w inter tir es ~,&. .
You r authorized Audi dea le r or a uthorized re­
pair facility can in form you about the maximum
permitted speed fo r yo ur tires.
.. Check the tire pressure after insta lling wheels
~ page 206.
The effectiveness of winte r tires is reduced great ­
l y when the tread is worn dow n to a depth of
0 .157 inch (4 mm). The characteristics of w inter
tires also decrease greatly as the tire ages, re­
gardless of the remai ning tread .
A WARNING
-Never drive faster than the maximum per ­
mitted speed for your t ires. This could cause
the tires to heat up too much . This increases
the risk of an ac cident be cause it can cause
the tire to b urst.
- Always adapt you r driv ing to the road and
t raff ic conditions. Dr ive ca refully and re duce
yo ur speed on icy or slippery roads. Even
w inter tires can lose tract ion on black ice.
@ For the sake of the environment
Reinstall summer tires at the approp riate
t ime, because they prov ide be tter h and ling
when roads a re free of snow and ice. S ummer
tires ca use less road no ise, tire wea r and fuel
consumption.
Wheels
{!) Tips
You can also use a ll season tires instead of
winter tires. P lease note that in some coun­
tries where w inter tires are required, only win­
ter tires w ith the
& symbol may be permit­
ted.
Snow chains
Snow chains improve traction in the snow .
.. On ly install snow chains on the front wheels .
T his applies a lso to vehicles with a ll whee l
drive .
.. Check and correct the seating of the snow
chains if necessary after driving a few feet . Fol ­
low the instructions from the manufactu rer .
.. Note the maximum permitted speed when dr iv­
ing wit h snow chains . Do not exceed 30 mph
(SO km/h).
Snow c ha ins not only improve the
driving in w in­
te r road cond itions , but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons .
Check with an authorized Audi dea ler or author­
ized repa ir fac ility to see if you may use snow
chains.
Use
fine-mesh snow chains. They must not add
more than 0 .41 inch (10 .5 mm) in he ight, includ­
i ng the cha in lock.
You must remove the chains when driving on roads that are
free of snow . When roads are free
of snow, snow cha ins can impair handl ing and
damage the tires, and the chains wi ll quickly be
dest royed.
A WARNING
Using incor re ct snow chains o r insta lli ng snow
cha ins incorrect ly can result in loss of ve hicle
control, which increases the risk of an acci­
dent .
(D Note
Snow ch ains can damage the rims/wheel cov­
ers * if the chains come into direct contact
