2012 AUDI A5 COUPE ignition

-Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause injury in a crash .
_&. WARNING
Forward-facing child restraints:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag .
- Never put the forward-facing child re­
straint up, against or very near the in­
strument 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 as possible before installing
the forward-facing child restraint. 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
Rearward-facing child restraints:
- A child in a rearward-facing child safety
seat installed on the front passenger
seat will be seriously injured and can be
killed if the front airbag inflates -even
with an Advanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
- Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances.
-A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air-
Child Safety 197
bag System. The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­ ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on .
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rearward-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
Activating the convertible locking
retractor
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­ er 's instructions when installing a child re­
straint in your vehicle. To activate the conver­
tible locking retractor:
.. Place the child restraint on a seat, prefera­
bly on the rear seat.
.. Slowly pull the belt
all the way out.
.. Route it around or through the child re­
straint belt path
c:> ,&. .
.. Push the child safety seat down with your
full weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for
that seating position .
.. Guide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat.
.. You should hear a "clicking" noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt out of the retractor. The con ­
vertible locking retractor is now activated .
.. Make sure that the red release button is fac­
ing away from the child restraint so that it
can be unbuckled quickly. .,. •

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine .
If a vehicle with a conventional energy system
is not driven for a long period of time , the bat­
tery is discharged by idling current consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to start the engine .
Intell igent energy management in your vehi­
cle hand les the d istribution of electrical ener­
gy. Starting ab il ity is markedly improved and
the life of the battery is extended.
Basically, energy management consists of
batt ery di ag nosis, idlin g current man ag e­
m ent
and dyn ami c en ergy manage ment .
Batter y diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature. This determ ines the current
state of charge and the powe r of the battery.
Idling curr ent man agement
Idling current management reduces ene rgy
consumption while the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy supply to the va rious electr ical compo ­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
i nd ividua l consumers are gradual ly t urned off
to prevent excess ive d ischarge of the bat tery
and thus maintain starting capability .
Dynam ic en ergy management
While the vehicle is being driven, dynamic en­
e rgy management dist ributes the energy gen­
e rated according to the needs of the individu­
a l components.
It reg ulates cons umption, so
that more electrical energy is not being used
Int ellig ent technolog y 211
than is being generated and ensures an opti ­
mal state of charge for the battery.
(0 Tips
- But even energy management canno t
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
r:!) page 212,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short -distance
driving, in city traffic and during 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 electri­
cal components are turned on . In this in­
stance energy is be ing consumed but none is
being generated.
It is in precisely these situations that you will
notice energy management actively regulat ­
ing the d istribution of energy .
Vehicle stands for an e xtended peri od
If you do not drive your vehicle over a period
of several days or weeks, e lectr ical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in ­
ta ins start ing capability over a longer period .
Some of the convenience functions may not
operate, such as the interior lights or the power seat adjustment . The convenience
funct ions w ill be available again when you
tu rn o n the ign ition and start the engine.
With the eng ine tu rned off
If you listen to the radio, for examp le, w ith
the engine turned off or use other MMI func -
tions, the battery is be ing discharged.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not continue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your personal driving style
- operating conditions
- technical lim itations
I f you anticipate what you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 215
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.. Avo id unnecessary accelerating and brak ing .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you ant icipate what is going to
happe n next, you will need to brake less and,
t hu s, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maxi -
mum speed .
Accelerat ing gently reduces fuel consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

216 Driving and environment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.,. Shut the engine off when you are not driv­
ing the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rail ­
road crossings, or at traff ic lights that have
l ong wa its on red. Turning the engine off for
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However , wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it runs properly and economically . The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of oi l used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances with a
cold engine .
The engine and cata lytic converter have to
reach their optimal
operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km), ll>

If the engine compartment is cleaned at any
time with grease removing solutions
1>, or if
you have the engine washed, the anti-corro­
sion treatment is almost always removed as
well. It is therefore essential to have a long­
lasting corrosion protection reapplied to all
surfaces , seams, joints and components in the
engine compartment .
.8, WARNING
Be aware: The engine compa rtment of any
motor vehicle is a potentially hazardous
area .
- Before working in the engine compart­
ment, be s ure to read the informat ion
