The side airbags are located in the sides of the
fro nt seat backrests
~ fig. 200 and the rear
backrest* facing the doors. They are ident ified
by the word "AIRBAG".
Th e si de airbag syste m basicall y consis ts o f:
- the e lectronic control module and external
s ide impact senso rs
- the two side airbags located in the sides of
the front backrests
- two rear side airbags (as an ordered
option)
-the a irbag warning light in the instrument
cluster .
The airbag system is monitored electron ically
t o make certain that it is functioning properly
at all times . Each time you turn on the igni
tion, the airbag system indicator l ight will
come on for a few seconds (self diagnostics) .
The s ide a irbag system supplements the safe
ty belts and can help to reduce the risk of in
jury to the dr iver's, front and rear* passeng
er's uppe r torso on the side of the veh icle that
i s st ruck in a side collision . T he a irbag dep loys
only in s ide impac ts and on ly when the veh icle
acceleration registered by the control un it is
h igh eno ugh. If this rate is below the refer
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re
sult of the collision. It is not possible to de
fine an a irbag trigger ing range that will cover
every possible angle of impact, since the cir
cumstances will vary conside rably between
one co llision and another. Important fac tors
include, for examp le, the nat ure (hard o r soft)
of the impac ting objec t, the ang le o f impact ,
vehicle speed, etc . ¢
page 196, Important
safety instructions on th e side airbag system .
Aside from their normal safety function , safe
ty belts work to he lp keep the driver or front
passenger in position i n the event of a side
coll is ion 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 oc
cupant restraint system in your vehicle . Al
ways remember that the side airbag system
A irbag system 195
can on ly help to protect you if you are wearing
your safety be lt and wearing it properly. This
is another reason why you should always wear
your safety be lts, not just because the law re
quires you to do so¢
page 170, General
notes.
It i s important to remember that wh ile the
supplementa l side airbag system is designed
to reduce the likelihood of ser ious injuries,
other injur ies, for example, swelling, bru is ing,
and mi nor ab rasions ca n also be assoc iated
with deployed side airbags . Remember too,
s ide a irbags w ill 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 ve hicle damage are no t necessa rily a n in di
cat ion o f ove r-sensitive or failed airbag a ctiva
t ion . In some coll is ions, both front and side
airbags may inflate . Remember too, that air
bags will deploy only once and only in certain
k inds of co llisions -yo ur safety be lts are a l
ways there to offer protection in those acc i
den ts in which airbags are no t supposed to
deploy or when they have a lready deployed .
The side airbag system w ill n ot deploy:
- when the ignition is tu rned off
- in side co llisions when the acceleration
meas ured by the sensor is too low
- in front-end collisions
- in rea r-end col lisions
- in rollove rs .
In some types o f accidents the front airbags,
s ide curtain airbags and s ide a irbags may be
triggered together.

can result in there being insufficient energy
avai lab le to start the engine .
I ntell igent energy management in your vehi
cle handles the distribution of electrical ener
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Basically , energy management consists of
battery diagnosis , idling current manage
ment
and dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery volta ge, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo
nents. Data from battery diagnosis is consid
ered.
Depending on the battery's state of charge,
individua l consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being dr iven , dynamic en
e rg y management distributes the energy gen
erated according to the needs of the individu
a l components. It regulates consumption, so
that more ele ctrical energy is not being used
than is being generated and ensures an opti mal state of cha rge for the battery.
{D) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
c> page 22 7,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability .
The battery is seve rely taxed in shor t-distance
driving, in city tra ffic and dur ing the cold time
of year . Abundant electrical energy is re
quired, but only a little is generated . It is also
critical if the engine is not running and e lectri
ca l components are turned on . In this in
stance energy is being consumed but none is
being generated.
It i s in precisely these situations that you will
notice energy management actively regulat
ing 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 , e lectr ica l compo
nents are gradually cut back or sw itched off.
T his reduces energy consumption and main
ta ins start ing capability over a longer period .
Take into consideration that when you unlock
your vehicle , some conven ience functions ,
s uc h as the inte rior lights or the power seat
adjustment, may not be available. The con
venience functions will be available again
when you turn on the ignition and start the e ngine .
With the engine turned off
If you listen to the radio, for example, w ith
the engine turned off or use other MMI func
tions, the battery is being discharged .
If starting capability is jeopardized due to en
ergy consumption , the following warning ap
pears 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 automatically after 3 minutes . If
you w ish to continue using the funct ions, you
have to sta rt the eng ine.
1111>
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be
come discharged. This happens most ly when
litt le energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili
brium, consumers which require especia lly
large amounts of energy are temporarily cut
back or switched off. Heating systems in par
ticular requ ire a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they h ave been temporar ily cut back or switched
off. These systems will be available 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 engine idle
speed the additional energy required is gener
ated and the battery is charged .
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ab ility of the engine to start, th is
is shown in the instrument cluster display
with the following driver message:
(•i Low battery charge: battery will be
charged while driving
This notification reminds you that the starting
capability of the engine may be limited. As
soon as you start driving again, the battery
will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If th is driver notification appears after the ig
nition is turned on or while driving and it goes
out again after a wh ile, the battery has been
adequately recharged.
Intelligent technology 22 7
Driver notification appears and does not
go out again
If this driver notification appears after the ig
nition is turned on or whi le driving and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ab ility is
restricted . Have the battery checked as soon
as possible by an authorized Aud i dealer or
qualified workshop.

The chains should cross under the trai ler
tongue to prevent it from dropping in case of
separation from the hitch.
([) Note
If you are going to tow a trai le r, you must
activate the trailer operation mode
¢ page 154, Towing a trailer.
Driving instructions
Driving with a trailer always requires extra
care and consideration .
To obtain the best poss ible handling o f vehicle
and trai ler, p lease note the following:
~ Do not tow a loaded trailer whe n your car it
self is not loaded.
~ Be especially careful when passing other ve
hicles.
~ Observe speed limits .
~ Do not drive at the maximum permissible
speed .
~ Always apply brakes early.
~ Monitor the temperature gauge .
Weight distribution
Towing a loaded trai ler with an empty car re
sults in a highly unstable distribution of
weight . If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con
trol. This means that the tow vehicle should be loaded to the extent possible and permissi
ble, wh ile keeping the trailer as light as poss i
ble under the circumstances . Whenever possi
b le, transfer some cargo to the luggage com
partment of the tow vehicle wh ile observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficult it be
comes for the drive r to control the rig. Do not
drive at the maximum permissible speed. Re
duce your speed even more if load, weather or
Trailer towing 237
wind conditions are unfavorable -pa rticularly
when going downhill.
Reduce veh icle speed
immediately if the trail
er shows the slightest s ign of sway ing .
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some a reas, speeds
for vehicles tow ing tra ilers are lower than for
regular veh icles .
Always apply brakes early. When driving
down hill, shift into a lower gear to use the en
gine braking effect to s low the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge¢ page 10
must be observed carefully. If the need le
moves close to the upper end of the scale, re
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light in
the instrument cluster starts flashing ., pull
off the road, stop and let the engine
idle for
about two minutes to prevent heat build -up .
A WARNING ~
Anyone not properly restrained in a mov-
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
prov ided by Audi.
Trailer towing tips
Important to know
Your vehicle handles differently when towing
-
a trailer because of the additional weight and
different weight distr ibution . Safety, perform
ance and economy will great ly depend on how
carefully you load your trailer and operate
your rig .
Before you actua lly tow your tra iler, practice
turning, stopping and backing up in an area away from traffic. Keep practicing until you
have become completely familiar w ith the way.,.
