[I) Tips
• When defrosting/defogging the windows, air flows from outlets
(D ,@ and @. To defrost or defog the windows as rapidly as poss ible,
air outlets ® should be opened
fully with the adjuster wheels.
• When the air conditioner is working, cooled air w ill flow primarily
from outlets @,® and @. To assure adequate cooling, outlets ®
and © should never be completely closed.•
Using the climate controls economically
Using the climate controls prudently can help save fuel .
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should use
the air conditioner only when necessary. Also please note the
following points:
- If you want to save fuel, switch off the air conditioner .
- If you are going to drive with the windows open, switch off
the air conditioner.
By reducing the amount of fuel you use, you also reduce the amount
of polluta nts emitted into the air. •

& 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

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

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

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 .,_

IJIII Checking and filling
-------=:---- =------------------------------------
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

of oil that conforms to A ud i oil specificat ion VW 507 00, in case you
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.
0 Note
• If you use engine oil that does not express ly co nform to A udi o il
spe cifica tion VW 507 00, very ser ious and ve ry expens ive da mage to
