2013 AUDI A6 warning

A WARNING ,~
Always adjust your driving to road and traf­
fic conditio ns. Do not let the extra safety
a ff orded by all-wheel dr ive tempt you into
taking extra risks.
-Although the all-wheel dr ive is very ef­
fec tive, a lways remember that b raking
capacity is limited by t ire traction . You
sho uld the refore no t dr ive at excess ive
speeds on icy or sl ippery road surf aces.
- On wet road su rfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to slide on top of the water
(aq uaplaning). If this sho uld occ ur, you
will have no warning from a sudden in­
crease in engine speed as with a front­
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions - risk of c rash.
Energy management
Starting ability is optimized
E nergy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a veh icle wit h a conven tional energy system
is not d riven for a long period of time , the bat ­
tery is discha rged by idling c urre nt cons umers
(e .g. immobilizer) . In certain circumstances it
can result in there being ins ufficient ene rgy
avai lab le to start the engine.
I ntell igent energy ma nagement in your vehi­
cle hand les the d istribution of electrical ener ­
gy . Starting abi lity is mar ked ly improved and
the life of the battery is extended .
B asically, energy management consists o f
battery diagno sis , idling current manage­
ment
and dynamic ene rgy man agement.
Battery diagnosis
B atte ry d iagnosi s con tinuously dete rmines
the state of the battery. Se nso rs dete rm ine

temperature . This de termines the current
state of charge and the power of the battery.
Idling current management
Idli ng cur ren t management reduces energy
consump tion while the vehi cle is st anding.
With the ig nition switched o ff, it controls the
energy supply to the various electrical compo­
nents . Data from batte ry diagnosis is consid ­
ered.
Depend ing on the ba ttery's state of cha rge,
individual consumers a re g radually turned off
to prevent excessive discharge of the battery
and th us maintain starting capability.
Dynamic energy management
While t he vehi cle is being dr iven, dyn ami c en­
ergy management distr ib utes the energy gen ­
erated according to the needs of the individ u­
al components. It regulates consumption, so
that more e lectrical 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
lim ited.
- If start ing ability is t hreatened, the indi­
cator light(•] appears ¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in s hort-distance
driv ing, in city traff ic and during the cold time
of year. Ab undant electrical energy is re­
quired, but on ly a little is generated .
It is also
crit ical if the engi ne is not r unning and elec tri­
ca l components are tu rned on . In this in­
s tance ene rgy is be ing consumed b ut none is
being genera ted.
It is in precisely these situations that you will
notice ene rgy management active ly reg ulat-
i ng t he d istr ibu tion of ene rgy. ..,_ •

198 Intelligent technology
Vehicle stands for an e xte nded period
If you do not drive you r vehicle over a pe riod
of several days or weeks, elec trical compo ­
nents are grad ually cut back or switched off.
This reduces energy cons umption and main­
tains starting capab ility over a longer period.
Some of the conven ience f unctions may not
ope rate, such as the inter ior lights or the
power seat adjustment. T he conven ience
f u nctions w ill be ava ilable again when you
switch on t he ignit io n and start the engi ne.
With the engine turned off
If you listen to t he radio, for example, with
the eng ine turned off or use othe r MMI func­
tions, the battery is b eing d ischa rged .
I f starting capab ility is jeopa rdized due to en­
ergy consumpt ion, the following warning ap­
pears in the MMI disp lay:
Please start the engine soon or the system
will be turned off.
T he warning ind icates that the system will be
turned off automatically afte r 3 m inutes. If
you wish to cont inue using the f unctions, you
have to start the engine.
With the engine running
A ltho ugh elect ric al e nergy is genera ted when
the veh icle is being driven, the bat tery can be ­
come d ischarged. This ha ppens most ly w hen
litt le energy is be ing generated and a great
deal consumed and the battery 's state of
charge is not optimal.
To br ing the ene rgy balance back into equili­
brium, cons umers which require especially
large amo unts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular requ ire a great dea l of energy. If you
n otic e, fo r example, that the heated seats * or
the heated rea r window a re not heat ing, t hey
h ave been te m po rar ily cu t bac k or swi tched
o ff . T hese sys tems will be availa ble again as
soon as the energy ba lance has been restored .
You will a lso not ice that engin e idl e spe ed has
been in cr eased sligh tly. This i s norm al and no t
a ca use fo r con cern. By incre asin g engi ne idle speed
the a dditional energy requi red is gener ­
ated and the battery is charged.

Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km) .
For the first 600 mile s (1,000
kilometers ):
.,. Do not use full throttle.
.,. Do not d rive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
.. Avoid high engine speeds.
From 600 to 1,000 miles (1 ,000 to
1,500 kilometers):
.. Speeds can gradually be increased to the
maximum pe rm iss ible road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to high speeds
when it is cold. This applies whether the
transmission is i n N (Neutra l) or in gear.
After the break- in peri od
.. Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale
¢ page 11.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
i n. How well this break-in p rocess is done de­
pends to a considerable extent on the way the
ve hicl e is driven d uring the first 1,000 miles
(1,500 ki lome ters).
(D Note
Extremely h igh engine speeds are auto­
mat ica lly reduced. However, t hese rpm
lim its are progr amme d for an eng ine well
r u n- in, not a new engine .
Driving and environment 199
@) For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds -upshifting ear ly saves f uel,
reduces noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
.&, WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be sure to remember
this dur ing the f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llowing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 ki lomete rs) afte r they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&. .
D uring the brea k-in period, yo u should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mounta in passes .
.&, WARNING
New b rake pads don't have the best stop­
p ing power and must be "broken-i n" dur­
ing the initi al 100 to 150 miles (150 to
200 kilometers) o f no rma l ci ty driving . You
can compensate for this by pressing the b rake peda l more firm ly . This also applies
later when new pads are installed.

200 Driving and en vir onm ent
Catalytic converter
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¢ page 220,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 230, Adding engine oil~-
., Never try to push- or tow -start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt­
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 230.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not switch off the ignition while the
vehicle is moving .
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec­
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam ­
aged.
T his is espe cially true for ve hicles with low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles .

Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full b raking effect.
([) Note
-Vehicle components such as the eng ine,
transmission, suspension or electr ical
system can be severely damaged by driv­
i ng th rough water.
- Always switch off the Start-Stop-System
when driving through water~ page 76.
(D Tips
-Check the depth of the water before dr iv­
i ng t hrough it.
- Do not stop the veh icle, dr ive in reverse
or switch the eng ine off whe n driving
through water .
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep fo r your vehi­
cle to drive t hrough safely.
- Avoid dr iv ing through salt water because
i t can cause corrosion.
Dri vin g and en vironm ent 201
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, environmenta l impact, and
wear on your eng ine, brakes and tires largely
depend on three factors:
- your pe rsonal d riving style
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut you r
fuel consumpt io n by 10-15 percent . T his sec­
tion w ill give you some tips on how you can
help the env ironment and your po cketbook.
@ Tips
The consumption estimates as published
by ENVIRONMENTAL PROT ECTI ON AGENCY
( E PA) a nd Tra nspo rt Canada may no t corre­
spond to your actual consump tion on the
road, which will va ry 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 f ue l when they a re ac ­
ce le rat ing. If you ant icipate what is going to
happen next, you will need to brake less and,
th us, acce lerate less . Let the vehicle coast
whenever possible - for examp le when you see
that the next traff ic light is red.

202 Driving and environment
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.,. Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el 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 driv­
ing the vehicle .
... Do not warm up the veh icle by letting the
engine run at idle .
The idling phase is automat ically reduced for
vehicles w ith the Start/Stop system .
It is effi ­
cient to switch
off the engine in vehicles with­
out the Start-Stop-System when stopped at
railroad crossings and long red lights . Turning
the engine
off for just 30-40 seconds saves
more f uel than is burned by starting the en­
gine again.
It takes a long time for the engine to wa rm 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.
([) 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 veh icle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
.,. Have your vehicle serviced at regu la r inter-
vals .
By having your veh icle reg ularly se rviced by an
Audi dealer he lps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
ho ld its value, it also affects
fuel consump ­
tion .
Check your oil each time you fill your tank.
The amou nt of oi l 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 .
You must drive your veh icle about 3,000 miles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fuel 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 ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em ission control system and could lead
to damage.
- Do not alter or remove any component of
t he 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

204 Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
@ Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
c:::> page 204, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­ ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. A lways
check with the trai ler hitch manufacturer to
make sure that you are using the cor rect
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trai ler hitch ball mount. This prevents the
h itch from causing damage should your veh i­
cle be struck from behind
c:::> A .
Trailer brakes
If your trailer is equipped with a brak ing sys­
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the trailer.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your Audi dealer for correct
wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors. It is important
that you
always have clear v is ion to the rear .
A WARNING
--
After removing the trailer hitch, do not
store it in your vehicle . In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
A tra ile r for your vehicle is limited to a typical
class 1 or class 2 tra ile r.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shift ing forward,
backward or sideways.
Never allow a passenger to ride in a trailer
c:::> A in Driving instructions on page 206 .
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is important that the cooling system 's
performance is up to the additional load.

206 Trailer towing
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine 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 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the display turn on .
For more information about indicator lights,
refer to. ¢
page 16 .
A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wear ing the restraints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle handles differently when towing
a trailer because of the additional weight and
different weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig .
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
have become comp lete ly familiar with the way
your ve hicle-trai ler comb ination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a tra iler generally requi res
steering act ion opposite to that when backing
up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the trailer, you wi
ll need a larger than normal
turning radius.
When passing, remember that you cannot ac­
celerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass . After passing, a llow
plenty of room for your trailer before chang ­
ing lanes again.
Avoid jerky starts , sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load¢
page 285.
Parking on a slope
Do not park on o slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
.,. App ly the foot brake .
.. Have someone pla ce chocks under both the
vehicle and the trailer wheels.
.. With chocks in place, slowly release the
brakes until the whee l chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake.
.. Select the P selector lever posit ion .
When restarting after parking:
.. Apply the foot brake.
.. Start the engine.
.. Select the D/S selector lever position .
.. Release the parking brake and slowly pull
out and away from the wheel chocks .
.,. Stop and have someone retr ieve the wheel
chocks .
Ill-
