Safety first
Child Safety
Booster seats and safety be lts
Properly used booster seats can help protect children
weighing between about 40 lbs. and 80 lbs. (18 kg and
36 kg) who are less than 4
ft. 9 in. (57 inches/1.45 meters)
tall.
Fig . 150 Rear seat:
child properly
restrained in a booster
seat
The vehicle's safety belts alone will not fit most children
until they are at least 4 ft. 9 in. (57 inches /1.45 meters) tall
and weigh about 80 lbs. (36 kg). Booster seats raise these
children up so that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt can help
protect them in a crash.
- Do not use the convertible locking retractor when using
the vehicle's safety belt to restrain a child on a booster
seat.
- Always position the shoulder portion of the safety belt
midway over the child's shoulder. If you must transport
an older child in a booster seat on the front passenger
seat, you can use the safety belt height adjustment to
help adjust the shoulder portion properly.
- Always make sure that the shoulder portion of the safety
belt neve r rests against or across the child's neck.

& WARNING (continued )
• It is safer to install a forward-f acing child safety seat on the rear
seat.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>
page 167. Special precau­
tions apply when installing a child safety seat on the front
passenger seat:::::,
page 147, "Child restraints on the front seat -
some important thing s to know ".
& WARNING
Always take special precautions if you must install a forward or
rearward-facing child restraint on the front passenger's seat in
exceptional situations :
• Whenever a forward or rearward -facing child restraint is
installed on the front passenger seat , the PASSENGER AIR BAG
OFF light must come on and stay on whenever the ignition is
switched on.
• If the PASSENGER AIR BAG OFF light does not come on and stay
on , perform the checks described=>
page 156, "Monitoring the
Advanced Airbag System ".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on whenever the ignition is switched
on .
• Improper installation of child restraints can reduce their effec ­
tiveness or even prevent them from providing any prote ction .
• An improperly installed child restraint can interfere with the
airbag as it deploys and seriously injure or even kill the child .
• Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier .
• Never place additional items on the seat that can increase the
total weight registered by the weight-sensing mat and can cause
injury in a crash .
& WARNING
Forward-facing ch ild restraints :
• Always make sure the forward-facing seat has been designed
and certified by its manufa cturer for use on a front seat with a
passenger front and side airbag .
• Never put the forward-facing child restraint up , against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range , as far away from the
airbag as possible before installing the forward-facing child
re straint. The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.

Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer 's instruc­
tions when installing a child restraint in your vehicle. To
activate the convertible locking retractor:
- Place the child restraint on a seat, preferably on the rear
seat.
- Slowly pull the belt
all the way out.
- Route it around or through the child restraint belt path
=>& .
- Push the child safety seat down with your full weight to
get the safety belt really tight .
- Insert the belt tongue into the buckle for that seating
position.
- Gu ide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
Controls and equip­
ment Safety first Vehicle operation
- You should
hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pul ling on the belt. You should no longer be able to
pull the belt out of the retractor. The convertible locking
retractor is now activated .
- Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.
- Pull on the belt to make sure the safety belt is properly
tight and fastened so that the seat cannot move forward
or sideways more than one inch (2.5 cm).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.
• Always buckle the child safety seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a crash.
• Always make sure the seat backrest to which the child restraint
is installed is in an upright position and securely latched into place
and cannot fold forward. Otherwise, the seat back with the child
safety seat attached to it could fly forward in the event of an acci­
dent or other emergency situation.
• Always read and heed all WARNINGS whenever using a child

Vehicle care Do-it-yourself service Technical data

The exclusive use of unleaded fuel is critically important for the life
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust system may come in contact with dry grass, brush, fuel
spill or other material which can cause a fire.
• Do not apply additional undercoating or rustproofing on or
near the exhaust manifold, exhaust pipes, catalytic converter or
heat shields . During driving, the substance used for undercoating
could overheat and cause a fire.
0 Note
• Be aware that just one tank filling with leaded fuel will already
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level~
page 230.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the catalytic converter. This could result
in overheating of the converter, requiring its replacement.
• To assure efficient operation of the Emission Control System :
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as improper use of the
vehicle will impair the function of the emission control system
and could lead to damage.
Controls and equip­ ment Safety first Vehicle operation
Driving and environment
<£' For the sake of the environment
Even
when the Emission Control System is operating properly, the
exhaust gas can have a sulfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used . Using a different brand of fuel may help, or filling the
tank with lead-free super grade gasoline. •
Applies to veh ic les : with diesel particulate filter
Diesel particu ate filter
The diesel particulate filter filters nearly all of the soot particles out
of the exhaust. The filter cleans itself automatically under normal
driving conditions. If the filter cannot clean itself (for example,
because you are only driving short distances), the filter becomes
clogged with soot and the symbol for the diesel particulate filter
illuminates ~
page 32.
& WARNING
• Do not park your vehicle over flammable materials such as
grass or leaves because the high temperature of the diesel partic­
ulate filter could start a fire.
• Do not apply an underbody protectant in the exhaust system
area or a fire could start.
[ i] Tips
• When the diesel particulate filter becomes saturated, the engine
speed increases to approximately 1,500 rpm while the vehicle is in
motion to initiate the cleaning of the diesel particulate filter auto­
matically without the warning lamp lighting up. If the warning lamp
still appears, you should drive to a qualified workshop. •

long waits on red. Turning the engine off for just 30 -40 seconds
saves more f ue l than i s bu rned star ting 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 em issions are especial ly

0 Note
Do not leave en gine idling unattended after starting. If warn ing
lights should come on to indicate improper operation, they would
go unheeded . Extended idling also produces heat, wh ich cou ld
result in overheating or other damage to the vehicle or other
property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehicle serviced at regu lar intervals.
By having your vehicle regu lar ly serviced by an authorized Audi
dea ler he lps to ensure that it runs properly and econo mically . The
condition of your vehicle not only affects its safety and abi lity to
hold i ts va lue, it a lso affects fuel consumpt ion .
Che ck yo ur oil ea ch t ime you fill your t ank.
T he amount of oil used is related to engine load and speed.
It is nor mal for the oil consumption of a new engine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 mi les (5,000 kilometers)
before you can proper ly assess oil consumption .

Fewer short trips
Fuel consump tion will always be relatively hi gh on shor t
trips.
- Try to avo id driving short dista nces wi th a cold en gine.
The engine and cata lytic c onverter have to reach their optima l oper ­
ating temperature to reduce fuel consumption and noxious emis ­
sions effective ly .
• Just after starting, a cold engine in a mid-size car burns the fuel
at a poor rate of 6 -8 miles per gallon (30 -40 11100km). Half a mi le
down the road, the mileage improves to 12 MPG (20 1/100 km). It wi ll
take the engine no less than
two and a half miles (4 km) of driving to
warm up to its proper operat ing temperature and operate at a n
economic mileage . This exp lains why taking the car for short trips is
a ra ther waste ful convenience .
• The outs ide temperat ure is also critical in this regard. Your car
consumes more fuel in the winter than in the summer .•

Cleaning and protection -
----------------=-----=------
•
Safety belts
Only well-maintained safety belts work reliably when
needed.
-Keep belts clean.
- For cleaning, use a mild soap and water solution. Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash .
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them .
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your authorized Audi dealer.
• Always read and heed all WARNINGS and other information
=:, page 204. •
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine =:> &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts .
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
3l, or if you have the engine washed , the anti­
corrosion treatment is almost always removed as well . It is therefore
essential to have a long-lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the engine compart ­
ment.
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information
=:> page 215 . .,_
31 Use only the correct cleaning solutions. Never use gasoline or diesel fuel.
