& WARNING
Changing the vehicle 's suspension including use of unapproved
tire-rim combinations can change Advanced Airbag performance and increase the risk of serious personal injury in a crash .
• Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
• Never use tire-rim combinations that have not been approved
by Audi.
& WARNING
Item s stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electroni c control module and prevent the
Advanced Airbag System from work ing properly.
• Always make sure that nothing can interfere with the safety
belt buckles and that they are not obstructed . ..,

and for the different models of the same kind of child restraint
offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor­
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the

light.
Controls and equip­ ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot­
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with
t he requirements for advanced airbags with each and every chil d
restra int that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States Nationa l Highway Traffic Safety
Administration has published a list of specific type, makes and
mode ls of child restra ints that must be used to cert ify compliance of
the Advanced Airbag System in yo ur vehicle with the suppression
requirements of Federal Motor Veh icle Safety Standard 208. These

Vehicle care Do-it-yourself service Technical data

Driving and environment
This is especially true for vehicles with low-slung chassis (sports
chassis) and fully loaded vehicles. •
Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, env ironmental impact, and wear on your eng ine,
brakes and tires largely depend on three factors:
• your personal driving style
• operat ing conditions
• technical lim itations
If you anticipate what you need to do next and drive economically,
you can easily cut your fuel consumpt ion by 10-15 percent. This
sect ion wi ll g ive you some tips on how you can help the environment
and your pocketbook.
[I) Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not co rre­
spond to your actual consumption on the road, which will vary
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothl} and keep a lookout ahead
Vehicles use the most fuel when they are accelerating.
Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are accelerating. If you antici­
pate what is go ing to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible - for example when you see that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed.
Accelerating gently reduces fuel consumption, engine wear, and does
not d isturb the env ironment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds. If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half.
Never drive faster than the posted speed limit and weather condi ­
tions perm it. •
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 engine run at idle .
It makes sense to shut off the engine in traffic jams, when waiting for
trains to pass at railroad crossings, or at traffic lights that have long
wa its on red. Turn ing the eng ine off for just 30-40 seconds 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 noxious emissions are espec ially high
when the engine is warming up . So you shou ld drive away as soon as .,_

-------=:---- =------------------------------------
Please be sure to consu lt with your aut horized Aud i dea ler for infor­
m ation and availabili ty of the proper engine oil fo r yo ur vehicle's
diesel engine and fo r the latest technical informat ion .
Beca use t his spec ia l engine o il may not be avai lab le when need it, we

have to top off o il wh ile on the road.
& WARNING
Failure to use engine oil for your diesel engine that expressly
conforms to Audi oil specification VW 507 00 can cause engine
failure on the highway that can cau se a cra sh and serious per sonal
injury.
• Never use any amount of engine oil in the diesel engine that
does not conform to Audi oil specification VW 507 00 .
• Always carry with you an extra quart (liter ) of engine oil that
conforms to Audi oil specification VW 507 00
in case you must top
off the oil while on the road .
& WARNING
Improperly stored items can become airborne missiles, flying
through the vehicle causing serious personal injury in the event of
hard braking or an accident. To help reduce the risk of serious
personal injury:
• Always store extra quart (liter ) of engine oil for your diesel
engine in its original oil container that is securely closed in the
luggage compartment. Make sure the container is securely stored
and mounted.

The cooling system is sealed and genera lly requ ires little attention.
Th e cooling system has been filled at the factory wit h a permanent

mode ls; 60% for Canadian models). This mixture both ass ures the
nece ssary frost protec tion and p rotects meta l components in the
eng ine's cooling system from corrosion and scaling. It also raises the
boiling poin t of the co olant.
Do not red uce the co ncent ration of the coolant in the summer by
add ing p la in water.
The proportion of coolant additive must be at
least 50 % but not more than 60%

If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants) , you can adjust tire pressures to
those specified for normal vehicle load. Before operating the
vehicle at maximum load, you must increase the tire pressures to
those specified for maximum vehicle load

The tires and rims are essential parts of the vehicle's design. The tires
and r ims approved by Audi are spec ially matched to the characteris­
tics of the vehicle and can make a major contribution to good road
holding and safe handling when in good condition and properly
inflated =>& .
We recommend that all work on tires and wheels be performed by an
authorized Audi dealer. They are familiar with recommended proce­
dures and have the necessary special tools and spare parts as well as
the proper facilit ies for disposing of the old tires.
Authorized Audi dea lers have the necessary information about tech­
nical requirements for installing or chang in g ti res and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not ind ividually (for
example both front tires or both rear t ires together).
Be sure to read and heed the tir e pressure monitoring system*
information=>
page 264.
Always buy replacement radial tires that have the same specifications
as the tires approved for your veh icle by Audi . Replacement tires must
always have the same load rating specification as the original equip­
ment or approved opt iona l tires listed in the table=>
page 249.
Audi-approved spec ification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road­
holding, driv ing characteristics, and safety of the vehicle. The table (=>
page
249) lists specifications of the tires approved for the Aud i
models covered by your Owner's Literature.
The tire pressure label located either on driver's side B-p illar or inside
the fuel filler flap(=>
page 249, fig. 172) lists the specifications of
the original equipment tires installed on your ve hicle at the time it
was manufactured.
Federal law requires tire manufact urers to place standardized infor­
mation on the sidewall of all tires =>
page 2 5 7, fig. 17 5. This i nfor­
mation identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a t ire identification number
for safety standard certification and in case of a reca ll.
Tire specifications
Knowledge of tire specificat ions makes it easie r to choose the correct
tires. Rad ial tires have the tire specifications marked on the s idewall,
for examp le:
P225 / 45 R 17 91H XL
This contains the following informat ion:
P I ndicates the tire is for passenger cars (where applicable)
225 Nominal tire width in mm of the tire from s idewall edge to side-

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Aud i dealer for
more details .
Th e low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation . The numeral represents the ratio of
the tire's sidewall height in relation to its tread width expressed in
percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 252, "Checking t ire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact w ith
potholes, curbs, gullies or ridges on the road, particularly if the tire is
unde rinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle , we recomme nd that you observe the following precau ­
tions:
• Always maintain recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive ca refully on roads with potholes, deep gullies or ridges. The
impact from driving through or over such obstacles can damage your
tires. Impact with a curb may also cause damage to your tires .
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible. •
Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflat ion, which could eventually cause tire fa ilure . If
you believe that a tire may have been damaged, replace the tire as
soon as poss ible .
• Th ese tires may wear more quickly than others.
• Please a lso remember that, while these tires deliver responsive
hand ling, they may rid e less comfortably and make more noise than
other choices .
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio, ultra
high performance t ires originally installed on your vehicle are
intended for maximum dry and wet road perfo rmance and handling.
They are not su itable for cold, snowy or icy weather conditions . If you
drive under those circumstances, you should equip yo ur vehicle with
all-season or w inter tires, which offer better traction under those
conditions . We suggest yo u use the recommended snow or all-season
tires specified for your veh icle, or their equivalent .
Refer to =>
page 261 for more detailed information regard ing winter
tires. •

General notes 1
Each tire, including the spare (if prov ided) , shou ld be checked
month ly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or t ire

than the siz e indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper t ire inflation pressure for
those tires.)
