Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are necessary, how
they work and how to adjust and wear them correctly.
- Read all the information that follows and heed all of the
instructions and WARNINGS.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Safety belts are the single most effective means available to
reduce the risk of serious injury and death in automobile acci­
dents. For your protection and that of your passengers, always
correctly wear safety belts when the vehicle is moving.
• Pregnant women, injured, or physically impaired persons must
also use safety belts. Like all vehicle occupants, they are more
likely to be seriously injured if they do not wear safety belts. The
best way to protect a fetus is to protect the mother -throughout
the entire pregnancy. •
Number of seats
Your Audi has a total of four seating positions: two in the front and
two in the rear. Each seating position has a safety belt.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Never strap more than one person, including small children,
into any belt. It is especially dangerous to place a safety belt over
a child sitting on your lap.
• Never let more people ride in the vehicle than there are safety
belts available.
• Be sure everyone riding in the vehicle is properly restrained
with a separate safety belt or child restraint. •
Safety belt warning light~
Your vehicle has a warning system for the driver and (on
USA models only) front seat passenger to remind you
about the importance of buckling-up.
Before driving off, always:

- Fasten your safety belt and make sure you are wearing it
properly . ._

-Make sure that your passengers also buck le up and prop ­
erly wear the ir safety belts .
- Protect your children with a child restraint system appro-
priat e for the si ze and age of the child ren.
The warn ing light tin the instrument cluster lights up when the igni­
tion is switched on as a reminder to fasten the safety belts. In addi­
tion, you wi ll hear a war ning sound.
After the ignition is switched on, the warning tone will come on for abou t 6 seconds along with a t warn ing light in the inst rument
cluster if e ither the driver or (on USA models o nly) front seat
passenge r has not fastened their safety bel t. As soon as the driver
and front seat passenger have fastened the safety belt, the warning
tone will stop and the warning light will go out.
If both the driver and front seat passenger have not buckled- up
within about 24 seconds after the warning tone has stopped, the
wa rning tone w ill sound aga in for about 6 seconds. The warn ing tone
w ill sound repeatedly for about 6 seconds at 24 second interva ls unt il
bo th the driver and fron t passenger have bu ckled -up. The safety belt
warning system is active for about 5 minutes and during this time the
warning light in the instrument cluster wi ll stay on.
Fasten your safety b elt now and make sure that your pa ssengers
also properly put on their safety belt s. •

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for people
riding in vehicles .
Fig. 18 7 Unbe lted
occu pant s in a veh icl e
h ea din g for a wall
Fig . 18 8 T he veh icle
cr ash es into t he wall
Th e physical pr incip les are simple. Bot h the vehicle and the passen­
gers possess energy which varies with vehicle speed and body weight.
Enginee rs call th is energy "kine tic en ergy ."
The higher the speed of the vehicle and the greater the veh icle's
weight, the more energy that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor.
If the speed doub les
from 15 to 30 mph (25 to SO km/h), the energy increases 4 times!

Child restraints on the front seat - some
important things to know
- Be sure to read the important information and head the WARNINGS for important detai ls about children and
Advanced Airbags =:>
page 22 2.
Even though your veh icle is eq uipped with an Advanced Airbag
System, make certain that all ch ildren, especially those 12 years and
younger, a lways r ide in the back seat properly rest rained for the ir age
and size . The airbag on the passenger side makes the front seat a
poten tially dangerous place fo r a child to r ide. The front seat is not
the safest place for a child in a forward-facing c hild safety seat. It can
be a ve ry dange rous place fo r an infant or a child in a rearward-fac ing
seat.
T he Advanced Airbag System in your vehicle has been cert ified to
comply with the Req uirements of United States Federa l Moto r
Vehicle Safety Standard 208 as applicable at the time your vehicle
was ma nufactu red .
The Standard requires the front airbag on the passenger side to be tu rned off ("supp ressed") if a c hild up to abo ut one year o f age
restra ined in one of the rear -facing or forward -fac ing infant
restrain ts listed in Federa l Moto r Vehicle Safety Sta ndard 208 with
w hich the Advanced Airbag System in your veh icle was certified has
been installed on the front passenger seat. For a listing of the chi ld
restra ints that were used to cert ify complia nce w ith the US Safety
Standard
=> page 224.
T he PASSENGER AIR BAG OFF ligh t in t he inst rumen t panel tells you
when the front Advanced Airbag on the passenger s ide has been
tu rn ed off by the electronic con tro l u nit.
Eac h time you turn on the ign ition, the
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if th e fron t passenger seat is no t occupied, •
will stay on if there is a small ch ild or child restra int on the front
p assenge r seat,
• will go off if the front passenger seat is occup ied by an adult as
reg iste red by the weight-sens ing mat =:>
page 211, "Monitori ng the
Adva nced Airbag System" .
Th e
PASSENGER AIR BAG OFF light comes on when the control unit
detects a tota l we ight on the front passenger seat t hat req uires the
front airbag to be t urned off.
If the tota l we ight on the front passenger sea t is more than th at of a
typical 1 year-old child but less than the weight of a small adu lt, the
front airbag on t he p assenger s ide c an dep loy (the
PASSENGER AIR
BAG OFF
li g ht does not come on) . If the PASSENGER AIR BAG OFF
light does not come on, the front airbag on the passenger side has
not been tu rned off by the e lectron ic control u nit and can deploy if
the contro l unit senses an impact that meets the conditions stored in
its memory.
For e xample , the a irbag may deploy if:
• a small chi ld that is heavier than a typical 1 year -old child is on the
front passenge r seat (regardless of whether the child is in one of the
child safety seats listed =>
page 224), or
• a chi ld who has outgrown ch ild restra ints is on the front passenger
seat.
If the front passenger a irbag is turned off, the
PASSENGER AIR BAG
OFF
light comes on in the instrument cluster an d stays o n.
Th e front airbag on the passenger side may
not dep loy (t he
PASSENGER AIR BAG OFF light does not illum inate and stay lit) even
if a small adult or teenage r, or a passenger who is no t si tting upright
w ith the ir back against a non-recli ned backrest w it h their feet on the
vehicle floor in front of the seat is on the front passenger seat
=:>
page 178, " P rope r seat ing pos ition for the dr ive r" .
If the front passenger airbag deploys, the Federal Standard requ ires
th e airb ag to meet the "low risk" deployment criteria to red uce the
r is k of injury through interaction with the airbag. "Low risk" deploy­
ment occurs in those crashes t hat ta ke place a t lower decelerations as .,.

& WARNING (co ntinued )
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
c hild against the backrest, center arm rest , door, or roof .
• Always install rearwa rd-facing child restraints in the back seat.
• If you must install a rearward facing child safety seat on the
front passenger seat because of except ional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on ,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
& WARNING
If, in except ional circumstances, you must install a forward-facing
child re straint on the front pa ssenger's seat:
• Always make sure the forward-facing seat has been designed
and certified by its manufacturer for us e on a front seat with a
passenger front and s ide airbag.
• Never put the forward-facing child restraint up again st 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 a s po ssible, before installing the forward-facing child
restraint. The backrest must be adjusted to an upr ight position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on .•
Advanced Airbag System components
Th e front passenger seat i n your ve hicle has a lot of very im portant

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 203 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=>
page 219, fig. 203. They are identified 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
• the airbag warning light in the instrument cluster.
The 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 and front passenger's upper
torso on the side of the vehicle that is struck in a side collision. The
airbag deploys only in side impacts and only when the vehicle acceler­
ation registered by the control unit is high enough . If this rate is
below the reference value programmed into the control unit, the side
airbags will not be triggered, even though the car may be badly
Safety first Vehicle OP-eration
Airbag system
damaged as a result of the collision. It is not possible to define an
airbag triggering range that will cover every possible angle of impact,
since the circumstances will vary considerably between one collision
and another. Important factors include, for example, the nature
(hard or soft) of the impacting object, the angle of impact, vehicle
speed, etc.
=> page 220, "Important safety instructions on the side
airbag system" .
Aside from their normal safety function, safety belts work to help keep the driver or front passenger in position in the event of a side
collision so that the side airbags can provide protection.
The airbag system is
not a substitute for your safety belt. Rather, it is
part of the overall occupant restraint system in your vehicle. Always
remember that the side airbag system can only help to protect you if
you are wearing your safety belt and wearing it properly. This is
another reason why you should always wear your safety belts, not just
because the law requires you to do so=>
page 190, "General notes".
It is important to remember that while the supplemental side airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associated with deployed side airbags. Remember too, side
airbags will deploy only once and only in certain kinds of accidents -
your safety belts are always there to offer protection .
Vehicle damage, repair costs or even the lack of vehicle damage are
not necessarily an indication of over-sensitive or failed airbag activa­
tion. In some collisions, both front and side airbags may inflate.
Remember too, that airbags will deploy only once and only in certain
kinds of collisions -your safety belts are always there to offer protec­
tion in those accidents in which airbags are not supposed to deploy or
when they have already deployed.
The side airbag system will not deploy:
• when the ignition is turned off
• in side collisions when the acceleration measured by the sensor is
too low
• in front-end collisions

vi dual components. It regulates consumption, so that more electrical
energy is not being used than is being generated and ensures an
optimal state of charge for the battery .
[I] Tips
• But even energy management cannot negate the limits of physics.
Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
~ page 249, "Driver notification in the instrument cluster display" .•
What you should know
The highest priority is given to maintaining starting capa ­
bility.
Th e battery is severe ly taxed in short-distance driving, in city traffic
and during the cold time of year. Abundant electrical energy is
required, but only a little is generated.
It is also critical if the engine
is not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated.
It is in prec ise ly these sit uations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or sw itched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remo te key or power seat adjust­
ment, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine.
W ith the engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged .
If starting capability is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes.
Th e warn ing indicates that the system will be turned off automati­
cally after 3 m inutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrica l energy is generated when the vehicle is being
driven, the battery can become discharged. This happens most ly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
T o br ing the ene rgy balance back into equilibrium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heating systems in particular require a great deal of
energy .
If you notice, for example, that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off. These systems will be ava ilable again as soon as
the energy ba lance has been restored.
You will also notice that engine idle speed has been increased
slightly. This is normal and not a cause for concern. By increasing
eng ine id le speed the additional energy required is generated and the
battery is charged. •

Intelligent technology
--------------------------------------------------' '----'----
Driver notification in the instrument
cluster display
If battery power drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
with the following driver message:
Lo w b attery charge : batt ery will be charged while driving
Th is notification rem inds you that the starting capability of the
engine may be limited . As soon as you start driving again, the batte ry
w ill be recharged and the notification w ill go out.
Dri ver notification appears and goes out again
If th is dr iver notification appears after the ignition is turned o n or
while driving a nd it goes out again afte r a w hile, the battery has been
adequate ly recharged.
Driver no tification appears and does not go out
again
If th is dr iver notifica tion appears afte r the ignition is turned o n or
while driving and does not go out again, the battery 's state of charge
is not in the optimal range . Starting ability is restricted. Have the
battery checked as soon as poss ible by an au thor ized Aud i dea le r o r
qualified workshop. •

Observe speed limits. In some areas, speeds for vehicles towing
t railers are lowe r than for regular veh icles.
Always apply brakes early. When dr iv ing downh ill, sh ift in to a lower
gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge~ page 8 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditione r.
If the coolant temperature warning light in the instrument cluster
star ts flashing
-t- , pull off the road, stop and let the engine idle for
about two minutes to prevent heat bu ild-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi. u
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a tra iler because of the
additiona l weight and different weight distribution. Safety, perfor ­
mance and economy will greatly depend on how carefu lly you load
your trailer and operate your rig .
Before you actua lly tow your trailer, practice turning, stopping and
backing up in an area away from traffic. Keep pract icing until you have
become completely familiar with the way your vehicle-t railer combi­
nation behaves and responds.
Controls and equip­
ment Safety first Vehicle operation
Backing up
is d iff icult and requ ires practice . Backing up with a trailer
generally requires steering action opposite to that when backing up
your vehicle without a trailer.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop . To compensate fo r the
trailer, you will need a larger than norma l turning radius.
When passing, remember that you cannot accelerate as fast as you
normally would because of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for you r
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes .
[I) Tips
• Do not tow a trai ler during the break-in per iod of your vehicle.
• If you tow a tra iler, your Audi may requi re more frequent mainte­
nance due to the extra toad~
page 343. •
Parking on a slope
Do not park on a slope with a trailer. If it cannot be
avoided, do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle and the
trailer wheels.
- With chocks in place, slowly release the brakes until the
wheel chocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake .
- Move the se lector lever to
