2016 AUDI A6 oil temperature

-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment. You
could burn yourself. Let the engine cool off
first until you can no longer see or hear steam or coolant escap ing .
Q) Note
-Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At h igh outside temper­
atures or h igh engine load, the engine cou ld
ove rheat.
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving.
If the spoiler is damaged, this
could red uce the cooling effect and the en­
gine could then overheat . Ask your author ­
ized Audi dealer for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
You shou ld shift to the next lowest gear when
the speed is below 1500 RPM. The beginning of
the red zone in the tachometer indicates the maximum permissib le engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before reaching the red zone, you should shift into the
next h igher gear, choose the Dor S selector lever
position, or remove your foot from the accelera ­
tor pedal.
CD Note
The tachometer needle© c::> page 10, fig. 3
should only be in the red zone br iefly: other­
w ise, this increases the risk of e ngine dam-
age. The location where the red zo ne begins
varies depend ing on the eng ine.
@, For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.

Switching the ignition on/off
If you would like to switch the ignition on with­
out starting the engine, follow these steps:
.,. Press the
I STAR T ENGINE STOPI button with·
out pressing the brake pedal.
.,. To switch the ignition off, press the button
again. The needle in the tachometer moves into
the
OFF position.
The prewarming runs automatically in diesel
vehicles when the ignition is switched on.
Equipment that uses a lot of electricity is switch­
ed off temporarily when you start the engine.
If the engine should not start immediately, the
starting process is automatically stopped after a
short time. Repeat starting procedure .
Start-Stop-System*
Note the information in c> page 79, Start-Stop­
System.
A WARNING
- Never allow the engine to run in confined
spaces, because this increases the risk of as­
phyxiation.
- Never turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering no
longer function when you stop the engine.
You must use more force when braking or
steering. Because you cannot brake and
steer as you usually would, this could lead
to accidents and serious injuries. These
functions are still active if the Start-Stop­
System* has stopped the engine.
(D Note
Avoid high engine speed, full throttle, and
heavy engine load as long as the engine has
not reached operating temperature yet. You
could damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re­
duces unnecessary emissions.
-
Driving
{!) Tips
- After starting a cold engine, there may be a
brief period of increased noise because the
oil pressure must first build up in the hy­
draulic valve adjusters. This is normal and
not a cause for concern .
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that electrical equipment such as the exterior
lights are switched off.
Stopping the engine
.,. Bring your vehicle to a complete stop.
.,. Move the selector lever to the P or N position.
.. Press the
!START ENGINE STOP ! button
r:!>poge 74, fig. 80.
Steering lock
The steering locks when you turn the engine off
using the
I START ENGINE STOPI button and
open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off
If necessary, the engine can be switched off with
the selector lever in the R or D/S position. The
engine stops if you press and hold the
!START ENGINE STOP ! button at speeds below
6 mph (10 km/h) and press the brake pedal.
A WARNING
-Never turn off the engine until the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running.
If the en­
gine is off, you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually would, this
could lead to crashes and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P.
Otherwise, the vehicle could inadvertently
roll away.

CD Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Always switch the Start-Stop-System* off
when driving through water
9 page 79.
@ Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch 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 vehicle to drive
through safely.
-Avoid driving through salt water (corrosion).
Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
... Always use lead-free gasoline 9 page 208,
Fuel supply.
... Never run the tank down all the way to empty.
.,. Never put too much motor oil in your engine
9 page 220, Adding engine oil~-
.,. Never try to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
Driving and the environment
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or 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 mani­
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
CD Note
- Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic converter .
- Do not exceed the correct engine oil level
9page220.
- Do not drive until the fuel tank becomes
completely empty . The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requir­
ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur

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.
~ Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automat ically reduced for
veh icles w ith the Start-Stop-System. It is effi­
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at ra ilroad
crossings and long red lights . Turning the engine
off for just 30-40 seconds saves more fuel than is
b ur ned by sta rting the engine ag ain.
It takes a long t ime for the engine to warm up
fu lly when it is runni ng at idle . Howeve r, wear
and noxio us emiss ions a re espe cially high when
the eng ine is wa rm ing up. So you sho uld d rive
away as soon as you sta rt the engi ne and avoid
r u nning at high rpms whi le the engine is still
warming up .
(D Note
Do not leave engine id ling unatten ded a fter
starting . If warning lights should come on to
indicate im proper operation, they wou ld go
unheeded. Extended id ling a lso produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other proper­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
~ Have your veh icle serviced at regu lar intervals.
By having your veh icle reg ularly serviced by an
Audi dea ler helps to ensure that it runs proper ly
and econom ica lly. The condition of your veh icle
not on ly affects its safety and ability to ho ld its
va lue, it a lso affects
fuel consumption .
Check you r oil each time you fill your tank.
The amount of oil use d i s re lated to e ngine lo ad
a nd speed.
Driving and the envir onment
It is normal for the oil consumption of a new e n­
gine to reach its lowest value after a certain mi le­
age has been dr iven.
Yo u m ust dr ive your ve hicl e abou t 3,0 00 m iles
(S, 000 kilometers) befo re yo u can properly as ­
sess oil consumption .

CD Note
-Have your ve hicle maintained pro perly and
in acc ordance w ith the se rvice rec ommend a­
ti ons i n your W arra nty
& M ain ten ance book­
let . Lack of proper maintenan ce as we ll as
improper use of the ve hicl e w ill impair the
function of the em ission cont rol system and
co uld lead to damage.
- Do not alte r or remove any component of
the Emission Contro l System unless ap­
proved by the man ufacturer.
- Do not alte r or remove any device, such as
heat shields, switches, ign it ion w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System a nd othe r
im por tan t ve hicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~ Try to avo id driv ing short distances with a cold
eng ine .
T he engine and cata lytic conve rter have to reach
their opt imal
operating temperature to reduce
fuel consumpt io n and noxious emiss ions effec­
tively.
Just afte r starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 m iles per
gallo n (30-40 l/ 100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . Afte r about
2 .5 m iles (4 km), the eng ine is
at its p roper operat ing temperature and fue l
eco nomy has reached a no rma l level. So yo u can
see th at yo u should avoid short trips w heneve r
poss ible. .,.

Gasoline additives
A ma jo r concern among many au to manufactur ­
e rs is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline gr ades d iffer from one manu ­
facturer to ano ther, they have cer tain things in
common . All gasoline grades contain substances
that can cause deposits to collect on v ita l eng ine
parts, such as f uel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Fuel and R efueling
After an extended period o f using inadeq uate

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays read and h eed all WARNING S c:> .&.
in Working in the engine compartment on
page 216.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
l ubricat ing propert ies of oil d iminish gradually
during normal vehicle use.
Under some circumstances the engine o il should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the veh icle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have yo ur vehi­
cle whe re temperatures remain below freezing
for extended periods.
Ch eck ing and Filling
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Because of the problem o f proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that yo u have
your o il changed by an authorized
Audi dealer or
a qual ified service stat ion.
