acoustic park assist
A pplies to vehicles : with 4 -c h an nel a cou sti c par k ass is t
Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car.
How it wor ks
The acoustic park assist warning system (4 -channel acoustic park
assist) uses ultrasonic sensors to warn you when you are
backing
your vehicle close to an obstac le . The system 's 4 sensors are located
inside the rear bumper.
A cti va ting
The rea r acoustic park ass ist is activa ted whenever you shift into
Re verse . You will hear a warn ing tone when the system is on.
Reverse
With the car backing up in reverse gear, the collision warning sound
se ts in at the fo llowing
approximate d istances to obstacles:
st raight a ft 5ft(
1.5ml
a ngl ing aft of f ve hicle corners 2 ft (0.6 ml
As the distance shr inks, the time interval between the audible tones
grows shorter.
The sound changes to a continuous tone as soon as the remaining
d istance to an obstacle c loses to less than about 1 ft. (0.3 ml. The
steady tone cautions you that you have backed up hazardously
close and you risk co llis ion by back ing up any furt her .
Malfunction s in the system
If a warning tone is audible for about five seconds when you turn on
the ignition, there is a ma lfunction in the system . Have the prob lem
corrected by your authorized Aud i dealer.
Controls and equip ­
ment
Keep the sensors in the rear bumper clean and free from ic e so t hat
the acoustic park assist system can funct ion proper ly .
& WARNING
• Sensors have dead spaces in which object s cannot be
detected . Be especiall y alert for small ch ildren and animals , since
they are not always dete cted by the sensor s.
• The acousti c pa rk assist system is not a substitute for the
driver's own caution and alertne ss . Ultimate re sponsibility alway s
remains w ith the driver dur ing parking and s imilar maneuvers .
Alway s watch where you are driving _
0 Note
• Remem ber t hat low obstac les for wh ich a warning has already
been issued may "dive" below the system's sensing zone if the
veh ic le is be ing bac ked up cl oser. In this case, the warning sound
shutting off does
not indica te that you have cleared the obstacle .
Instead , impact is imminent.
• Objects such as trai ler hitches, barrier chains, narrow posts or
f ences covered by a th in laye r of pa int may not always be detected
by the system . T hey can sti ll damage your vehic le without a
warning.
[ i ] Tips
Keep the sensors in the rear bumper clean and free of snow and ice
so that the acoust ic park ing ass ist system can function properly .•

tongue from the buckle
-Push the red release button on the buckle ~ fig. 175. The
belt tongue will spring out of the
buckle~ &,.
-Let the belt wind up on the retractor as you guide the belt
tongue to its stowed position.
& WARNING
Never unfasten safety belt while the vehicle is moving. Doing so
will increase your risk of being injured or killed. •
Adjusting safety belt height
Use the safety belt height adjustment to change belt posi­
tion on the shoulder.
Fig . 176 Safety belt
height adjustor
The safety belt height adjustors for the front seats can be
used to adjust the height of the shoulder portion of the seat
belt so that it is positioned properly.
-The height adjustor can only be pushed down if the catch
is squeezed at the same
time => fig. 176 G).
-Press the handle slowly up or down 0 so that the
shoulder portion of the safety belt is positioned nearly
midway over the
shoulder~ &, in "Safety belt position"

& WARNING (continued)
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on ,
immediately install the rear -facing child safety seat in a rear
seating posit ion and have the airbag system inspected by your
Audi dealer .
• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-sensing mat in the seat and register more weight
than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
serious or even fatal injury to the child.
• If , in exceptional circumstances , you must install a forward ­
facing child restraint on the front passenger seat , always move the
seat into its rearmost position in the seat 's fore and aft adjust­
ment range , as far away from the airbag as possible. 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 .
& WARNING
• If the PASSENGER AIR BAG OFF light does not go out when an
adult is sitting on the front passenger seat after taking the steps
described above , make sure the adult is properly seated and
restrained at one of the rear seating positions .
• Have the airbag system inspected by your Audi dealer before
transporting anyone on the front passenger seat .

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 181 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=> fig. 181 and the rear backrest* facing the doors. They are identi­
fied by the word "AIRBAG".
The side airbag system basically consists of: • the electronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
• two rear side airbags (as an ordered
option)
• the airbag warning light in the instrument cluster .
Th e airbag system is monitored electronically to make certain that
it is functioning properly at all times. Each time you turn on the igni­
tion, the airbag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety belts and can help
to reduce the risk of injury to the driver's, front and rear*

Gasoline additives
A major concern among many auto manufacturers is carbon
depos it build-up caused by the type of gasoline you use.
A lthough gasoline grades differ from one manufacturer to another,
they have certain things in common. All gaso line grades contain
substances that can cause deposits to co llect on vital engine parts,
such as fue l injectors and intake valves. A lthough most gaso line
brands include additives to keep engine and fue l systems clean,
they are not equal ly effective .
Audi reco mmends using TOP TIER De tergen t Gasoline. For more
information on TOP T IER Detergent Gasoline, please go to the offi ­
cia l website (www.toptie rgas .com).
After an extended period of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance .

prevent the formation of harmful deposits, sometimes called
"sludge", that over time can lead to expensive repairs.
At the time of printing, engine oils available in the U .S . and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So
always be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal
condi tions where you drive. You can use oil wi th a viscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions .
However, if engine oil viscosity grade SAE 5W40 is not available, you
can also use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we strongly recommend
that you always carry with you an extra quart (liter) of oil that
expressly conforms to the VW 502 00 specification, in case you have
to top off the oil while on the road.
Only if the level of the oil is at or below the minimum mark on the
oil dipstick -and no oil that expressly conforms to Audi oil standard
VW 502 00 specifications is available - may you top off with a high
quality engine oil, preferably synthetic -based , that meets ACEA A3,
ACEA A5 or ACEA B5, API SL or ILSAC GF -3 specifications, but even
then, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40 .
However, during the entire time between oil change intervals, never top off with more than a total of 0
.5 qt/liter engine oil that does not
conform to Audi oil specification VW 502 00.
For more information about engine oil that has been approved for
your vehicle, please contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa.com or www.audicanada.ca. Here you will also find a
current list of oils (manufacturers, brand names etc.) that conform
to Audi oil standard VW 502 00.
Changing the engine oil
The engine oil and oil filter must be changed according to the
mileage (kilometers) and time intervals specified in your vehicle's
Maintenance & Warranty booklet. Do not exceed these intervals -
harmful deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor.
Under some circumstances the engine oil should even be changed
more frequently . Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to follow recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Maintenance & Warranty booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in

Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to prov ide effect ive lubrication and cool ing of in ternal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumption varies from engine to engine
and may change significantly over the life of the engine . Typically,
eng ines wi th a specified break -in period
(see ~ page 243) consume
more oil during the break -in period than they consume after oi l
consumption has stabi lized .
Under norma l condit ions, the rate of o il consumption depends on
the quality and viscosity of the oil, the RPM (revo lutions per minute)
at whic h the engine is operated, t he amb ient te mperature and road
conditions. Further factors are the amount of oil dilution from water
condensatio n or fuel residue and t he oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump ­
t ion may increase over time until rep laceme nt of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil consu mption can be estab lished or specified. T here is no a lternative
to regu lar and frequent checking of the oil level, see
Note .
If the yellow eng ine o il level warni ng symbol in the instrument
cluster ~ lights up, you should check the oil level as soon as
possible
with the oil dipstick ~ page 277 . Top off the o il at your
earl iest
convenience~ page 278.
& WARNING
Bef ore you che ck anything in the eng ine comp artment , alway s
read and heed all WARNINGS
~ & in "Working in the engine
c ompartment " on
page 27 3.
0 Note
Driving with an insuff ic ient oil level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pres sure warning displ ay "e:7: is n ot an indi cator of the oil
level . Do not rel y on it. Instead, check the oil level in your engine at
regular inter vals, preferably ea ch time you refuel , and al way s before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oi l, we reco mmend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that t he accurate measurement of oil consumptio n requ ires great
care and may take some time. Your Audi dealer has instructions
about how t o measure oil cons umpt ion accurately. •

To reduce the risk of personal injury if you must change the engine
oil in your vehicle yourself :
• Wear eye prote ction .
• To reduce the risk of burns from hot engine oil , let the engine
c ool down to the touch .
• When removing the oil drain plug with your fingers, stay as far
away as po ssible . Always keep your forearm parallel to the ground
to help prevent hot oil from running down your arm.
• Drain the oil into a container designed for this purpose , one
large enough to hold at least the total amount of oil in your engine.
• Engine oil is poisonous . Keep it well out of the rea ch of ch ildren .
• Continuous contact with used engine oil is harmful to your
skin . Always prote ct your skin by washing oil off thoroughly with
soap and water.

"MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine
compartment on the le ft side
~ page 275.
The fluid level may drop slightly after some time due to the auto ­
matic adjustment of the brake pads. This is not cause for alarm.
If the brake fluid level fal ls
considerably below the "MIN" mark, the
brake warning/indicator light (U .S . models :
BRAKE, Canadian models:

oughly checked by an authorized Audi dealer or qua lified workshop
and the cause corrected. If the brake fluid level is too low, the brake
warning/indicator light will illuminate . Contact an authorized Audi
dea ler
immedi atel y.•
Changing brake fluid
H ave the brake fluid changed by an experienced techni ­
cian.
Brake fluid absorbs mo isture from the air . If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The bo iling point of the brake fluid wil l a lso
decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
e ver y tw o year s. Always
use new brake fluid which conforms to Federal Motor Vehic le Stan­
dard "FMVSS 116 DOT
4".
The brake fluid rese rvo ir can be difficult to reach, therefore, we
recommend that you have the brake fluid changed by your autho­
rized
Audi dealer . Your dealer has the correct tools, the right brake
fl uid and the know-how to do this for you.
