Child restraints on the front seat - some
important things to know
- Be sure to read the important information and heed the WARNINGS for important details about children and Advanced Airbags =:>
page 231.
Even though your veh icle is eq uipped with an Advanced Airbag
System, make certain that all children, 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
potentially dangerous place fo r a child to r ide. The front seat is not
the safest p lace for a child in a forward-facing c hild seat . It can be a
very d angerous pla ce fo r an in fant or a ch ild in a rearwa rd-faci ng sea t.
The Advanced Airbag System in your vehicle has been cert ified to
comply with the req uirements of United States Federa l Motor Vehicle
Safety Standard
208 as applicable at the time your vehicle was manu­
factured .
T he S ta n dard requi res the front airbag on the passenger side to be
turned off ("suppressed") if a child up to about one year of age
restra ined in o ne of the rea r-facing or forward -fa cing in fant
restra ints listed in Federa l Motor Vehicle Safety Standard
208 with
w hich the Advanced Airbag System in your ve hicl e was ce rtified has
been installed o n the front passenger seat . For a listing of the ch ild
restraints that were used to certify compliance with the US Safety
Standard=>
page 233 .
The PASSENGER AIR BAG OFF light in the instrument panel tells you
w hen the front Advanced Ai rbag on the passenge r side has been
turned off by the electronic control unit .
Eac h time you t urn on the ign ition, the
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if the front passenger seat is not occupied,
• will stay on if there is a small ch ild or child rest rai nt on the front
passenger seat, •
will go off if the front passenger seat is occup ied by an adult as
registe red by t he weigh t-sens ing ma t:::::>
page 217, "Moni toring the
Advanced Airbag System" .
Th e
PASSENGER AIR BAG OFF light comes on when the control unit
detects a tota l we igh t on the front passenger seat t hat req uires the
front airbag to be turned off.
If the total we ight on the front passenge r sea t is more than that of a
typical 1 year-old child but less than the weight of a small adu lt, the
front ai rbag on the passenger side can dep loy (the
PASSENGER AIR
BAG OFF
lig ht does not come on). If the PASSENGER AIR BAG OFF
light does not come on, the fro nt airbag on the passenger side has
not been tu rned off by the e lectro nic cont rol u nit and can deploy if
the cont rol unit senses an impact that meets the conditions stored in
its memory.
Fo r example , the a irbag may deploy if:
• a small child that is heavier than a typical 1 year-old child is on the
front passenge r seat (regard less of whet her the child is in one of the
child seats listed:::::>
page 233), or
• a chi ld who has outgrown ch ild restra ints is o n the front passenger
seat.
If the fron t passenger a irbag is turned off, the
PASSENGER AIR BAG
OFF
light comes on in the instrument cluster and stays on.
Th e front a irbag on the passenger side may
not dep loy (the
PASSENGER AIR BAG OFF li ght does not illum inate and stay lit) even
if a small ad ult o r teenage r, or a passenger who is not sitting upright
w it h th e ir back against a non-recli ned backrest w it h their feet on the
veh icle floor in front of the seat is on the front passenger seat
=>
page 188, "Prope r seat ing pos ition for the dr ive r".
If the front passenger airbag deploys, the Federal Standard requires
t he airbag to meet the " low risk" deployment criteria to red uce the
r isk of injury through interaction with the airbag. "Low risk" deploy­
ment occurs in those crashes that ta ke place a t lower decelerations as
defined in the elec tronic control unit:::::>

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants .
Fig. 218 Side airbag
locat ion in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=> fig. 218 and the rear backrest facing the doors. They are identified
by the word "AIRBAG" .
The side airbag system basically consists of:
• the electronic control module and external s ide impact sensors
• the two side airbags located in the sides of the front backrests
• two rear side airbags
• the airbag warning light in the instrument cluster.
Th e airbag system is mo nitored electronically to make certain that it
is funct ion ing properly at all times. Each time you turn on the igni­
tion, the airbag system indicator light wi ll 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 passenger's
upper torso on the side of the vehicle that is struck in a side collision.
The air bag deploys on ly in s ide impacts and only when the vehicle
acceleration registered by the contro l unit is high enough. If this rate
Safety first Vehicle OP-eration
Airbag system
is below the reference value programmed into the control unit, the
side airbags will no t be triggered, even though the car may be badly
damaged as a result of the collision . It is not poss ible to define an
airbag triggering range that wi ll cover every possib le 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 226, "Important safety instructions on the s ide
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
co llision 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 veh icle. Always
remember that the side airbag system can only help to protect you if
you are wearing yo ur 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 197, "Genera l notes".
It is important to remember that while the supp lemental 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 dep loy 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 a irbag activa­
tion. In some collisions, both front and side airbags may inflate .
Remember too, that airbags will deploy only once and on ly in certain
kinds of collisions -your safety belts are always there to offer protec­
tion in those accidents in wh ich airbags are not supposed to deploy o r
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
toolow

vidual components. It regulates consumption, so that more electrical
ene rgy 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 259, "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 severely taxed in short-distance driving, in city tra ffic
and during the cold time of year. Abundant electrical energy is
required, bu t on ly 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 isely these situations 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 switched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Be aware that when you unlock your vehicle, some of the convenience
functions may not operate, such as the Convenience key, the remote
control or the power seat adjustment. The convenience functions will
be available aga in when you turn on the ignition and start the eng ine.
Controls and equip­
ment Safety first Vehicle operation
With 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 capab ility 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.
The warning indicates that the system will be turned off automati­
cally after 3 minutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged . This happens mostly
when little energy is being generated and a great dea l consumed and
the battery's state of charge is not optimal.
T o bring the energy 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 w ill be ava ilable again as soon as
the energy balance 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
engine idle speed the additional energy required is generated and the
battery is charged. •

cluster display

Trailer towing
"---------------------------------------------------
Speed
T he higher the speed, the more difficult it becomes for the driver to
control the rig. Do not dr ive at the max imum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icu larly when go ing downhill.
Reduce vehicle speed
immediately if the tra iler shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for veh icles towing
trailers are lower than for regu lar vehicles.
Always apply brakes early. When driv ing dow nhill, shift in to a lower
gear to use the eng ine braking effect to slow the veh icle. Use of the
bra kes alone can cause them to overheat and fail.
Coolant temperature
Th e coolant temperature gauge~ page 10 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 conditioner.
If the coolant temperature warning light in the instrument cluster
starts flashing
_f_ , pull off the road, stop and let the engine idle for
about two m inutes to prevent heat build-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.•
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a trailer because of the
additiona l weight and different weight distribution. Safety, perfor- mance and economy will greatly depend on how carefully you load
your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopp ing and
backing up in an area away from traffic. Keep practicing until you have
become completely familiar with the way your vehicle-t railer comb i­
nation behaves and responds.
Backing up is difficult and requires practice. Backing up with a trailer
generally requires steering action oppos ite to that when backing up
your vehicle without a trai ler.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop. To compensate for the
trailer, you will need a larger than normal turning radius .
When passing, remember that you cannot accelerate as fast as you normally would because of the added load . Make sure you have
enoug h room to pass. After passing, allow plenty of room for your
trai ler before changing lanes again.
Avoid jerky sta rts, sharp tur ns or rapid lane changes.
W Tips
• Do not tow a trailer during the break-in per iod of your veh icle.
• If you tow a trai ler, your Audi may require more frequent mainte­
nance due to the extra load
~ page 361. •
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 p lace chocks under both the vehicle and the
trailer wheels . ._

& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, los s of control, collision, serious personal injury or even
death.
• When the warning symbol appears in the instrument
cluster , stop and inspect the tires.
• Incorrect tire pressure and/or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The dr iver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
& WARNING (co ntinued )
• Only when all tires on the vehicle are filled to the correct pres­
sure, the tire pressure monitoring* system can work correctly .
• The use of incorrect tire pressure values can lead to accidents or
other damage. Therefore it is essential that the driver observe the
specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure monitoring system*.
• Always inflate tires to the recommended and correct tire pres­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation, sudden tire failure and loss
of control.
• Excessive speed and/overloading can cause heat build-up,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest service station
to check the tire pressure and add ai r as required.

App lies to veh icles: with Tire pressure monitoring syste m
Introduction
The tire pressure monitoring system monitors air pres­
sure in all four road wheels and the spare tire* while the
vehicle is moving.
As soon as the tire pressure monitoring system senses a significant
loss of air pressure in one or several tires, text messages and yellow
symbols appear in the instrument cluster display to alert the driver.
The
1warning light in the instrument cluster comes on when the tire
is significantly underinflated
=> page 17.
The warning light
L also illuminates in the case of a system malfunc­
tion.
The system continuously receives radio signals from sensors located
inside each tire.
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1.5 psi (0.1 bar). The tire warms up while the
vehicle is moving and tire pressure rises. So you should adjust tire
pressure only when the tires are
cold, when the temperature of the
tires is roughly the same as the ambient air temperature.
In order to keep the tire pressure monitoring system properly cali­
brated, tire pressure on all four tires and on the spare tire* should be
checked at regular intervals, adjusted if necessary and saved in the
proper setting (recommended pressure)=>
page 330.
The tire pressure is shown on the tire pressure label. On USA vehicles,
the tire pressure label is located on the driver's side B-pillar. On
Canada vehicles, the tire pressure label is located either on the
Safety first
driver's side B-pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured. For recommended tire
pressures for normal load conditions, please see chapter
=> page 310.
The current temperatures and pressure of your tires can be viewed in
the MMI
=> page 329.
& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly under-inflated. You
should stop and check your tires as soon as possible, and inflate
them to the proper pressure as indicated on the vehicle's tire pres­ sure label =>
page 310. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure. Under­
inflation also is likely to impair the vehicle's handling and stop­
ping ability.
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
<£> For the sake of the environment
Driving with under-inflated tires reduces fuel efficiency and tire tread
life.
(I) Tips
• Each tire, including the spare*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 310.
• The tire pressure monitoring system helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure. .,,,

___ T_ i_ r _e _s_ a_n_ d_ w_ h_ e_e_ l_ s _______________________________________________ _
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature .
• When tires are replaced, the sensors and valves should not be
detached or exchanged . Only the valve core needs to be replaced and,
if necessary, the valve and the wheel electronics replaced .
• The tire pressure monitoring system on your Audi was calibrated
usiing tires with the "AO" or "RO" identification. We recommend
using these tires.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system. Other­
wise the system will register a malfunction and a fault message will be displayed. For more information, contact your authorized Audi
dealer.
• Adjust the tire pressure and store the pressure in the tire pressure
monitoring system to the load you are carrying=:>
