ECO mode AUDI A5 CABRIOLET 2014 Owner's Manual

Switching off
• Drive faster than 9 mph (15 km/h), or
• take the vehicle out of reverse gear. The
acoustic parking system is immediately de­
activated, and the rear view camera picture is deactivated automatically after a period
of about 15 seconds, or
• switch off the ignition.
The delay in deactivating the camera provides
an uninterrupted view behind the vehicle es­
pecially when maneuvering in tight parking
spaces and prevents the picture from turning
off the every time you sh ift out of reverse .
If the warning message appears in the display but not the rear view camera picture, read and
confirm the warning message . The acoustic
d istance signal is always active.
If you press a function button on the MMI
control console, the rear view camera picture
disappears . The rear view camera picture reap­
pears the next time you park.
Further information on the warning message
and the MMI control console can be found in
the MMI instruction booklet.
A WARNING
- Only use the rearview camera to assist
you if it shows a good, clear picture. For
example, the image may be affected by
the sun shining into the lens, dirt on the
lens or if there is a defect.
- Use the rearview camera only with the
rear lid completely closed. Make sure any
objects you may have mounted on the
rear lid do not block the rearview cam­
era.
(D Tips
- The rear v iew camera picture is available
as soon as the MMI Display or the MMI is
switched on, or the start-up phase is
completed.
- The sensors must be kept clean and free
of snow and ice for the park assist to op­
erate.

Homelink
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
lights , etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to rep lace
three different remote controls from dev ices
in your home with one universal remote. Th is
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes place near the center of the radiator
grille. There is a control module attached at
this location .
A one-time programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling code¢
page 120 for vehicles without
the
MMI*.
& WARNING
-
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federa l safety stand­
ards. Th is includes any garage door open­
er mode l manufactured before April 1,
1982.
-A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Using a garage door
opener without these features increases
risk of serious injury or death.
Homelink 11 7
-For safety reasons never re lease the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its electrical components - an
overheated mo to r i s a fire haza rd!
- To avoid possib le injuries or property
damage, please always make abso lutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

Homelink signa l and operate when the Home ­
Lin k button is pressed . N ow you may prog ram
t h e other buttons as needed .
(D Tips
- Programming the rolling code can be
perfor med quicke r and more easily with
the help of a se cond person .
- If d iff iculties should ar ise when pro­
gramming the rolling code, consult the
operating instructions fo r th e garage
door opener or o ther dev ices for po ssible
so lutions.

154 Airbag system
-Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only once. After an airbag has been deployed,
it must be replaced with new replace- ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­ rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electronic control
unit. Some suspension changes can, for

same kind of child restrain t offered by child
restraint manufacturers.
T he weight ranges for the ind iv idual types,
makes and models o f ch ild restra ints tha t the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-o ld child have been
stored in the control unit of the Advanced A ir ­
bag System. When a child res traint is being
used on the front passenger seat with a typi­
cal 1 year-old ch ild, the Advanced Airbag Sys­
tem compares the we ight measured by the
weight sens ing mat with the info rmat ion s to r­
ed i n the electron ic cont rol unit.
The electron ic control unit a lso registers the
tension on the front passenger safety be lt .
The te nsio n on the safety be lt fo r the front
p assenger seat will be d iffe ren t fo r an ad ult
who is properly using the safety belt as com­
pared to the tension on the be lt when it is
used to attach a child restraint to the seat.
T he sensor below the latch for the safety be lt
for the front seat passenger measures the
t ension on the be lt. The input from this sen­
sor is then used with the we ight to "decide",
whether there is a ch ild restrai nt with a typ ical
1 year-o ld child on the front passenge r seat
and whether or no t the airbag must be turned
off.
Child restraints and Advanced Airbags
Regard less o f the child res traint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use with an airbag. Always be sure
that the child restraint is properly insta lled at
one of the rear seat ing pos itions .
If in excep­
tional c ircumstances you must use it on the
fr ont passenge r seat, caref ully read all of the
information on c hild safety and Adv ance d Air­
bags an d heed a ll of the app licable WAR N­
I NGS . Make certai n that the child restraint is
correctly recognized by the weig ht-sensing
mat inside the front passenger seat, that the
front passenger airbag is turned off and that
Child Sa fet y 163
the a irbag s tat us is a lways cor rect ly signaled
by the
PASSENGER AIR BAG OFF light .
Many types and models of child res traints
have been available over t he years, new mod ­
els are introduced regu larly incorporating new
and improved designs and o lde r models are
ta ken o ut of product ion . Ch ild restraints are
not standa rd iz ed. Child restraints of the same
type typically have d ifferent weights and si zes
and different 'footpr ints, ' the size and shape
of the bottom of the ch ild restra int that sits
on the seat, when they a re insta lled on a vehi­
cl e sea t. T hese d iffe rences make i t vir tually
i mpossible to certify compl ian ce wi th t he re­
quiremen ts for advanced airbags with each
and every ch ild restraint that has eve r been
so ld in the past or wi ll be sold over the course
of the useful life of your veh icle.
For t his reason, the United S tates Na tional
Hig hway T raffic Safety Administration has
published a list of specific type, makes and
models of child restraints that must be used

-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Maintenance booklet.
- Lack of proper maintenance as well as
improper 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
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank with lead-free super
grade gaso line.
Shutting down vehicle
If you wou ld like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro­
sion prevention, maintenance and storage. Pay attention to add itional information con­
cerning the battery. Refer to¢
page 217.
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 tires largely
depend on three factors:
- your persona l driving style
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your
fuel cons umption by 10 -15 percent. This sec-
Driving and environment 189
tion wi ll give you some tips on how you can
help the environment and your pocketbook.
(0 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
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 fue l when they are ac­
ce lerating. 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 traff 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 maximum
speed.
Acce lerating gently reduces fue l consump­
tion, eng ine 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 l imit and weather con­
ditions perm it.

Modern eng ine lubrication has taken a quan ­
tum leap in the last few years . Many synt hetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional petrole­
um-based o ils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthetic or petroleum­ based engine oil, the oil that you use must
conform to Audi's oil quality standard
VW 502 00 to help keep your vehicle's engine running smoothly and help prevent the for­
mat ion of harmfu l deposits, sometimes called
"sludge", that ove r time can lead to expensive
r epairs.
At the t ime of pri nting, engine o ils available in
the U.S . and Canada that meet the exacting
specifications of Audi oi l standard VW 502 00
are synthetic engine oils. This does not mean, h owever, that every synthetic engine oil w ill
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oi l.
To help preve nt the format ion of harmful de­
posits use only oi l with the fo llowing spec ifi­
cations printed on the oil container:
Audi oil standard VW 502 00
O il conta iner labels may carry the specif ica­
tion s ingly or in comb inat ion w ith other des ig­
nations and oil qua lity standards.
Viscos ity
Engine oi ls are graded according to their vis­
cosity. The proper v iscosity grade oi l for your
engine depends on cl imactic or seasonal con­
d itions where you dr ive. You can use oil with a
viscosity grade of SAE SW40 across all tem­
pe rature ranges for normal d riving conditions .
However, if eng ine oi l viscosity grade SAE
SW40 is not avai lab le, you can also use viscos­
ity grade SAE SW-30 or SAE OW-40 as long as
it meets Audi o il quality standard VW 502 00
specifications.
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we st rongly recomme nd
that you always carry with you a n ext ra quart
Checkin g and fillin g 209
(li ter) of oil that exp ress ly con forms to the
VW 502 00 specificatio n, in case you have to
top
off the o il while on the road.
Only if the level of the o il is at or be low the
minimum mark -and no oi l that expressly
confo rms to Audi oil standard VW 502 00
spec ifications is available -may you top
off
with a h igh quality engine o il, preferab ly syn ­
thet ic-based, that meets ACEA A3 or API SM
spec ifications, but even then, only in v iscosity
grades SAE SW-40, SA E SW-30, o r SAE
OW- 40. However, dur ing the entire time be­
tween o il cha nge inte rva ls, never top
off with
more than a tota l of 0. 5 q t/liter engine o il
that does not con form to A udi oil specification
vw 502 00.

Audi C ustomer Re lations at 1 (800) 822 -2834
or visit our web site at www .a u diusa.com or
www.aud icanada.ca. Here you w ill also find a
current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
T he eng ine oi l and o il f ilter m ust be changed
according to the mileage (kilometers) and
time intervals specified i n your ve hicle's War ­
ranty
& Maintenance booklet. Do not exceed
these interva ls - harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changi ng the oil at the recommended inter­
vals is so very important beca use the lubricat­
ing propert ies of oil decrease gradually during
norma l veh icle use. If you a re not sure when
yo u have your o il cha nged, ask your author­
ized Audi Se rv ice Adv isor.
Under some circumstances the engine oil
shou ld eve n be changed more frequent ly.
Change oil more often if you dr ive most ly
sho rt distances, operate the ve hicle in dusty
areas o r most ly under stop-and -go traff ic con-
di tions, o r when you use your vehi cle where .,..

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
The cooling system has been filled at the fac­
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixture of specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with anticorrosion addi­ tives (50% for USA models; 60% for Canadian models). This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling.
It also raises the boil­
ing point of the coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­ cle heating and engine cooling system.
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distilled water is recommended.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢ .&.
in Working in the engine
compartment on page 206.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checking and filling 213
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in­
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G12++ or G13 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro­
sion can cause a loss of coolant and se­ rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
