safety belt is being used but will inflate at the position where the
safety belt is not being used. It is impo rtant that nothing in terfere
with the safety belt buckles so that the sensors can send the correct information about safety belt use to the electronic control unit.
& 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
Items stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electronic control module and prevent the
Advanced Airbag System from working properly.
• Always make sure that nothing can interfere with the safety
belt buckles and that they are not obstructed .
W For the sake of the environment
Undeployed airbag modules and pretensioners might be classified as
Perchlorate Material -special handling may apply, see
www.dtsc.ca.gov/hazardouswas te/perchlorate . When the vehicle or
parts of the restraint system including airbag modules and safety
belts with pretensioners are scrapped, all applicable laws and regu la­
tions mus t be observed. Your authorized Audi dealer is familiar w ith
these requirements and we recommend that you have your dealer
perform th is service for you .•

Airbag system
Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 202 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
~ fig. 202 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 se nsors
• 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 elect ronically 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 d iagnostics).
The side airbag system supp lements the safety belts and can he lp to
reduce the risk of injury to the dr iver 's, front and rear* passenger 's
upper torso on the side of the vehicle that is struck in a side collision.
The airbag deploys on ly in s ide impacts and only when the vehicle
acceleration registered by the control unit is high enough. If this rate

Aside from their norma l safety function, safety be lts work to he lp
kee p th e dr iver or fron t p asse n ger in posi tion in t he even t of a c olli­
sion so that the side cu rtain a irbags can provide protection.
T he a irbag system is not a substitute for your safety belt . Rathe r, it is
par t of the ove rall o ccu pan t res traint syste m in your vehicle . A lw ay s
remember t hat the airba g system can on ly help to protect you if you
a re we ari ng your safety bel t and wearing it prop erly. Thi s is ano ther
reaso n why you s hou ld always wea r your safety be lts, not just because
th e law requi re s you to do so=>
page 199, "G ene ral not es".
It is i mpo rtant to re m ember that while the s ide curta in airbag system
is des igned to help re duce the likelih ood of serious injuries, ot her

acc idents -yo ur safety belts are always there to offer protection.
The side curtain airbag system basically consists of:
• Th e electronic co ntro l mo dule an d external side impact sensors
• The side c urtai n airbags above the fro nt an d rea r side windows
• Th e airba g indic ator ligh t in the ins trumen t panel
Th e a irbag system is monitored elec tron ically to make certai n it i s
functioning prope rly at a ll times . Each time yo u turn on the ignition,
t h e airbag sys tem indicator ligh t w ill com e on for a few seconds (s elf
diagnostics) .
The side curtain airbag is not activated:
• if the ignition is tu rned off
• in side co llisions when the accelerati on measured by the sens or is
t o o low
• in fro nt-e nd coll isio ns
• in re ar -end co llisions.

& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position =>
page 83,
"General recommendations ".
• If the airbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The side curtain airbag may not work properly even
when the vehicle acceleration in a side collision is high enough to activate the airbag.~

fore-and-aft and lateral directions, the brake pressure and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continually
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the problem.
The vehicle is then stabi lized by the forces acting on the whee l during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are main ly applied on the wheel that is on the
outs ide of the curve. In the case of a vehicle that is
understeering
(tendency to slide out of the curve), the brakes are applied as needed
on the wheel that is on the inside of the curve or additionally on the
other wheels. An acoustic s ignal indicates when ESP brake application
cuts in=> &.
The system operates across the entire speed range in combination
with the ABS system ~
page 256 . If the Anti -Lock Brake System
(ABS) ma lfunctions, the ESP wi ll be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
will perform a self-test. As soon as the test is comp leted, the system
is in normal operating mode .
Offroad mode
ESP should normally be operated in normal mode because this
ensures maximum vehicle stability. If necessary, you can activate the
ESP offroad mode by pressing the button=>
page 252, fig. 220 to
obtain maximum traction and braking ability when driving off paved
roads at low speeds. In ESP offroad mode, the ESP indicator light
=> page 16 illuminates and the message ESP Offroad Caution!
Limited driving stability
appears briefly in the disp lay.
The ESP offroad mode can be useful in the following exceptiona l situ­
ations when slip or a highly effe ctive different ial loc king funct ion is
desirable. Examples:
Controls and equip­ ment Safety first Vehicle operation
•
when driving w ith tire chains,
• when driving in deep snow or on loose ground,
• when driving on uneven surfaces with the wheels severely
unloaded (articulation), and
• when rocking the vehicle loose a fter it has become stuck.
When the unusual situation is past, you should sh ift back to the
normal ESP operating mode by pushing the button again. The
message
ESP/ ASR on then appears briefly in the display.
Hill descent control
The hill descent control is switched on in ESP offroad mode. When
slowly descending steep gradients on loose ground or when the axles
are art iculated, hill descent control provides assistance by automati­
cally applying the brakes to keep vehicle speed constant. The vehicle
is also rende red easier to steer by select ive distribution of braking
force. Hill descent control intervenes when:
• the accelerator pedal is not pressed,
• the vehicle is travelling less than 12 mph (20 km/h),
• a steep gradient is detected,
• wheel behavior indicates loose ground or conditions with poor
adhesion (e.g. also axle articulat ion).
Hill descent control operates both dr iving forward and in reverse.
Active hi ll descent control is deactivated by pressing the accelerator
pedal until the conditions for activation already listed are met aga in .
& WARNING
• The Electronic Stabilization Program is nevertheless subject to
the laws of physics . It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and
traffic conditions. Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks. ..

Audi oil standard VW 502 00 (vehicles with gaso line e ngine) or VW
507 00 (vehicles w it h die sel eng ine).
Changing the engine oil
The eng ine oil and oil fi lter mus t be changed according to the mileage
(kilome ters) and t ime intervals specified i n your vehicle 's Warranty &
Ma intenance booklet . Do not exceed these interva ls - harmful
deposi ts from o ld engi ne oil can reduce engine pe rfo rmance and ca n
lead to expensive engine repa irs.
C hangi ng the oil at the recommende d interva ls is so very imp ortant
because the lubricating properties of o il decrease gradually during
normal ve hicl e use. If yo u ar e not sure w hen you have yo ur oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the eng ine o il should even be changed
more fr eq uent ly. Chang e oil mor e of ten if you d rive mostly short
distances, operate the veh icle in d usty areas or mostly under stop­
and -go t raff ic condi tion s, or when you use yo ur vehicle where tempe r­
atures stay be low free zing po int for long periods.

Damage or malfunctions due to lack of maintenance
It is essentia l that you change your o il at the recommended intervals
using only en gine oil th at com plies wi th A udi o il st and ard VW 502 0 0

Engine oil consumption
To provide effective lubr ication a nd cooling for interna l eng ine parts,
a ll in ter na l c omb ustion e ngines use some oil. Oil cons umption v aries
from engine to engine and may change over the life of the eng ine .
E ngines te nd to use m ore oi l dur ing the b re a k-i n period t han t hey do
after ward, when oil consumption has stab ilized. Depending on t he
way the vehicle is driven and the operatin g cond itions, oi l cons ump ­
tion ca n be up to a 1 quart per 1,200 miles
(I lite r per 2,000 km) .
Consumptio n may be higher withi n th e first 3,000 m iles (5, 000 km) .
Under nor mal co ndi tions, the rate o f oi l consu mptio n depe nds o n oil
quality as well as viscosity, engine speed ( rpm), o utside tempe rature,
roa d condi tion s, the amou nt of o il d ilution caused by co nde nsed
water or fu el residue, and oxidation of the oil. O il cons umption may
increase wi th en gine we ar ove r time, un til repl aceme nt of worn
eng ine pa rts may become necessa ry.
Because of all these var ia bles, there is no standa rd o r "norma l" rate
of oil consumption .
We urge you to check the engine oil level at
regular intervals, preferably every time you fill the fuel tank, and
always before a long trip .
The oil pressure warning light
~ is not an indicator of low eng ine
oil level. If the warning light does not go out after starting, or
flashes while driving (above 1500 rpm), a buzzer will sound . It
indicates that the oil pressure is too low. Stop the engine immedi- _.,,

-Tires and wheels
5. Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the available
cargo and luggage load capacity of your
vehicle.
Check the tire sidewall(=>
page 3267
fig. 243) to determine the designated
load rating for a specific tire .•
Tire service life
The service life of tires depends on a lot of different
things including proper installation and balancing,
correct tire pressure and driving style.
