2015 AUDI RS7 SPORTBACK ESP

188 Intelligent technology
Anti-slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerat e and drive up hills .
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the o ther wheels.
This function is not availab le at higher speeds.
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll sw itch on aga in au­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the stee ring in critical s itua­
tions.
Selective wheel torque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in­
side of the curve o r both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more prec ise driving in curves. The
appl icable system may no t activ ate when driv­
ing in wet or snowy condi tions .
A WARNING
- The ESC and its integrated systems can­
not overcome the lim its posed by natural
physical laws. This is especia lly impor- tant on slippery or wet roads
. If the sys­
tems beg in acting to stabilize your vehi­
cle, you should immediately change your
speed to match the road and traffic con­
ditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Do ing so will increase the risk
of a loss of veh icle contro l, collision and
serio us pe rsonal inj uries.
- Always ad apt your speed to road, traffic
a nd wea ther conditions. The risk of los­
ing con trol of the vehicle increases when
driving too fast, especially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead . The ESC and its integrated sys­
tems cannot a lways prevent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistan ce sys tems that cannot al­
ways he lp to re duce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheel s are equipped with identi­
c al tires . D iffe ren t tire sizes can lead to a
reduction in engine power.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator lig ht

The rear spoiler deploys and retracts. Spoiler
operation can be set for automatic or manual
operat ion.
Automatic mode (normal operation)
-Automatic deployment: At a speed of about
80 mph (130 km/h), the rear spoiler deploys
automatically.
- Automatic retraction: When speed drops be­
low about SO mph (80 km/h), the rear spoil­
er retracts automatically.
Manual mode
- Manual deployment: Tapping briefly on the
switch

Indicator lights
I)/. Rear spoiler: system malfunction!
The rear spoiler may not have extended due to
a malfunction. This could change the vehicle's
driving characteristics at high speeds. Do not
exceed 85 mph (140 km/h). Drive to your au­
thorized Audi dealer immed iately to have the
malfunction corrected . The co lor of the indica­
tor light depends on the veh icle speed.
A WARNING
-Driving at higher speeds without the rear
spoiler deployed can impair handling char­
acteristics, making the vehicle harder to
control.
-Always make sure that the spo iler is de­
p loyed when driving at speeds over
85 mph (140 km/h) . If the rear spoiler
warn ing/ indicator light in the instru­
ment cluster comes on, the rear spoiler
may not have deployed.
- Never drive at speeds higher than
85 mph (140 km/h) if the spoiler is not
deployed. Have the spoiler inspected as
soon as possible by an authorized Audi
dealer or qualified workshop.
- Always obey speed limits and other traf­
fic laws.
A WARNING
Improper operation of the rear spoi ler can
cause crushing injuries.
- Always make sure that nobody, especially
children, is in the way when the rear
spoiler is deployed or retracted.
(D Note
- Never push the vehicle or apply force to
the rear spoiler -it could be damaged.
- To prevent damage to the rear spo iler do
not lean or place anything on it.
- Only operate the rear spoiler manually
when the rear lid is closed and the rear
spoiler moving parts are not blocked. Otherwise, damage cou ld occur.
(D Tips
Clean the spoiler compartment every 2 to
3 months. The spoiler compartment must
always be free of ice, snow, leaves or other
debris.

194 Intelligent technology
Basically, energy management consists o f
battery di agno sis, idling current manage­
ment
and dyn ami c ene rg y m anagement.
B attery diagno sis
Battery d iagnosis continuously dete rm ines
the state of the battery. Sensors determ ine
battery vo ltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling curr ent mana gem ent
Idling c urrent management reduces energy
consumption while the vehicle is standing.
With the ignition switched off, it contro ls the
energy s upply to the various e lectrica l compo­
nents . Data from battery diagnosis is consid­
ered.
D epending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excess ive d ischarge of the battery
and thus mainta in start ing capability.
Dynamic en erg y managem ent
While the vehicle is being dr iven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
a l components. It reg ulates cons umption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge 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
li mited.
- If starting ab ility is threatened, t he indi­
cator
light (•i appears ~page 16.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abu ndant e lectr ical energy is re- quired, but on
ly a little is generated .
It is also
critica l if the engine is not r unning and electri­
ca l components are turned on. In this in­
stance energy is be ing consumed but none is
being generated .
It is in precise ly these situations that you will
notice energy management active ly regu lat­
ing the d istribution of energy.
V ehicle stand s for an e xtended period
If you do no t drive your vehicle over a period
of several days or weeks, e lectrica l compo ­
nents a re g radually cut back or switched off .
This reduces energy consumption and main­
ta ins start ing capability over a longer period .
Some of the convenience functions may not
operate, such as the interior l ights or the
power seat adjustme nt. The convenience
funct ions wi ll be available again when you
switch on the ignition and sta rt the eng ine .
With the engine turned off
If you listen to the radio, for examp le, w ith
the engine turned off or use other MMI func­
t io ns, the battery is be ing discharged .
If starting capability is jeopardized d ue to en­
ergy consumption, the following warning ap­
pears in the MMI d isplay:
Please sta rt the engine soon o r the system
will be turned off .
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you w ish to continue using the funct ions, yo u
have to start the eng ine.
With the eng ine running
Although e lectrical energy is generated when
t h e vehicle is being driven, the battery can be­
come discharged . This happens mostly when
li ttle energy is being generated and a great
deal consumed and the battery's state of
c h arge is not opt imal.
To bring the energy ba lance back into equili ­
brium, consumers which requ ire espec ially
large amounts of energy are temporar ily cut
back or sw itched off . Heat ing systems in .,.

Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
T his is especially true for vehicles with low­
slung chassis (sports chassis) * and fully load­
ed veh icles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any h igher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
- Vehicle components such as the eng ine,
transmission, suspension or e lectrical
system can be severely damaged by driv­ ing through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not s top the veh icle, drive in reverse
or switc h the engine off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh sa lt water because

Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can help ensure that it is not
overstressed unnecessar ily during sporty dr iv­
ing.
When warming up, the vehicle is dr iven at a
maximum engine speed of 6000 RPM in order
to raise the engine o il temperature to a mini­
mum of 140
°F (60 °() . The t ires a lso on ly
reach the ir full road holdi ng capabi lity on ce
they have warmed up.
The cooli ng fan can cont inue to run in your ve­
hicle after the engine is switched off . Howev­
er, driving the veh icle to coo l it down is pa rti c­
ul arly important. Dur ing spo rty driving , the
engine and b rakes, the exhaust system, and
the transmission a ll become extremely hot.
Before you park the vehicle, you should drive
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down .
Catalytic converter
App lies to vehicles: wi th gaso line e ngi ne
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
"' Always use lead-free gasoline c:> page 206,
Fuel supply .
"' Never run the tank down all the way to emp­
ty.
"' Never put too much mo to r o il in yo ur eng ine
c:> page 21 S, Adding engine oil "t:::r..
"' Never try to push -or tow -start you r vehicle .
T he catalytic co nve rter is an efficient "clean ­
u p" dev ice bui lt into t he exhaus t system of
the ve hicle . The cata lytic converter bu rns
many of the pollutants in the exha ust gas be ­
fore they are re leased into the atmosphere.
T he exclus ive use of unleaded fuel is c ritical ly
i mportant for the life of the catalyt ic convert -
er and proper functioning of the engine .

@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION 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
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
~ Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
celerating. If you anticipate what is going to happen next, you will need to brake less and,
thus , accelerate less . Let the vehicle coast
whenever possible -for example when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
~ Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately at high
speeds . If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
~ Shut the engine off when you are not driving
the vehicle.
Driving and environment 199
~ 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 traffic lights that have
long waits on red. Turning the engine off for
just 30 -40 seconds saves more fuel than is
burned starting the engine 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
would go unheeded. Extended idling also
produces heat, which could 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
Audi dealer helps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven .

Vehicle care and clean ing
General information
Regular, proper care helps to maintain your
vehicle 's value. It can also be a requirement
when submitting warranty claims for corro ­
sion damage and paint defects on the body .
The required cleaning and care products can
be obtained from your authorized Audi dealer
or a qualified workshop . Read and follow the
instructions for use on the packaging.
A WARNING
-Us ing clean ing and care products incor­
rectly can be dangerous to your hea lth.
- Always store cleaning and care products
out of reach of children to reduce the risk
of poisoning.
@) For the sake of the environment
-Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not d ispose of leftover cleaning and
care products with household trash .
Car washes
-
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the
vehicle, the more the surface can be dam­
aged. High temperatures such as those
caused by sunlight increase the corrosive ef­
fect.
Before washing, wet heavy deposits w ith plen­
ty of water.
Also, wash the underside of your vehicle once road salt stops be ing used for the season.
Pressure washers
When washing your vehicles with a pressure
washer, always follow the operating instruc­
tions provided w ith the pressure washer . Th is
is especially important in regard to the pres ­
sure and spraying distance. Do not aim the
spray directly at seals on side w indows, doors,
Vehicle care and cleaning 201
the hood, the rear lid or the sunroof* or at
tires, rubber hoses, insulating material, sen­ sors* or camera lenses* . Keep a distance of at
least 16 inches (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use rotary nozzles or high pressure noz­
zles.
The water temperature must not be above
140 °F (60 °C) .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are
closed and the windshield wipers are
off. Fol­
low instructions from the car wash operator,
especially if there are accessories attached to
your vehicle.
If possible, use car washes that do not have
brushes .
Only use car washes where the vehicle re­
mains stat ionary and the wash ing equipment
moves around the vehicle when washing and
drying. Car washes that move the vehicle
through the car wash using a chain are not
recommended.
Washing by hand
Clean the vehic le starting from the top and
working down using a soft sponge or cleaning
brush. Use solvent-free cleaning products .
Washing vehicles with matte finish paint
by hand
To avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects, grease spots and finger­
pri nts are best removed w ith a special cleaner
for matte finish paint .
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use
too much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft mi-
crofiber cloth. ..,.
