ECO mode AUDI Q5 2013 Owner's Guide

There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- 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.
Airbag system 171
-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.

seat. The weight of a child restraint and its
"footprint" vary for different kinds of chi ld re­
straints and for the d ifferent models of the
same kind of child restraint offered by child
restra int manufacturers.
The weight ranges for the individual types,
makes and mode ls of ch ild restra ints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-old child have been
stored in the control unit of the Advanced A ir­
bag System. When a ch ild restrai nt is being
used on the front passenger seat with a typi ­
cal 1 yea r-old ch ild, the Advanced Airbag Sys­
tem compares the we ight measured by the
weight sensing mat with the in formation stor­
ed in the electronic control unit.
The ele ctron ic cont rol unit also registers the
tension on the front passenge r safety belt.
The tension on the safety be lt fo r the front
passenger seat will be different for an ad ult
who is properly using the safety belt as com­
pared to the tension on the belt when it is
used to attach a child restraint to the seat.
The sensor below the latch for the safety belt
for the front seat passenger measu res the
tension on the be lt. The input from this sen­
sor is then used with the we ight to "decide",
whe ther there is a ch ild restraint w ith a typ ica l
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off .
Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards a nd has been certified by its manu­
facture r fo r u se w ith an airbag. Always be s ure
that t he ch ild res traint is p rope rly insta lled at
one o f th e rear seat ing pos itions. If in excep­
tional c ircu mstances you must use it on the
front passenger seat, caref ully read all of the
info rmation on c hild safety and Advanced Air­
bags and heed all of the applicable WARN­
INGS. Make certain 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
the a irbag stat us is always cor rect ly signa led
by the
PASSENGER AIR BAG OFF light.
Many types and models of child res traints
have been available over the years, new mod­
els are introduced regu larly incorporating new
and improved des igns and older models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typically have d ifferent weights and sizes
and diff erent 'footpr ints,' the s ize and shape
of the bo ttom of the ch ild restra int that sits
o n t he seat, when they a re inst alled on a vehi­
cle sea t. Th ese d ifferences make it vir tually
impossible to certify compliance with the re ­
quirements for advanced airbags with eac h
and every child restra int that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For th is reason, the United States National
Highway Traffic Safety Adm inistrat ion has
published a list of specific type, makes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag
System i n your veh icle w ith the suppression

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 .
Fue l economy, environmental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your persona l driving style
- opera ting conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent . This sec­
tion will give you some t ips on how you can
he lp the environment and your pocketbook.
(D Tips
The consumpt io n estimates as published
by ENVIRONMEN TAL PROTECTION AGENCY
(EPA) and Transport Ca nada may not corre­
spond to your act ual consumption on the
road, wh ich 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 acce lerating and braking .
Vehicles use the most fue l when they are ac ­
celerating . If you anticipate what is go ing to
h appen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast
whenever poss ible -for example when you see
that the next traffic light is red.
Dri vin g and en vironm ent 207
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage .
" Try and keep well below your car 's maxi-
mum speed .
Acce lerat ing 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 h igh
speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed l imit and weather con­
ditions perm it.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
" Shut the eng ine off when you are not driv­
ing the vehicle .
" Do not warm up the ve hicle by letting the
eng ine run at id le.
The idling phase is automatically reduced for
vehicles with the Start -Stop-System* . It is ef ­
ficient to switch off the engine in vehicles
without the Sta rt-Stop-System * when stopped
at rai lroad cross ings and long red lig hts . T urn­
ing the engine off for jus t 30-40 seconds
saves more fuel than is b urned by s tarting the
engine again.
It takes a long t ime for the engine to warm up
f ully when i t is runn ing a t id le. However, wea r
and noxious emissions are especia lly high
when the engi ne is warming up. So you shou ld
drive away as soon as you start the engine and
avo id running at high rpms while the engine is
still warming up.
(D Note
Do not leave engine idling unattended af­
ter start ing . If warning lights sho uld come
on to indicate improper operation, they ..,.

Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded fo r operation away
from paved roads. In situations where slip or a
differential lock ing funct ion is required, the
ESC offroad mode can be act ivated
c> page 197 . Your Audi also has permanent
all-wheel drive in addition .
However, your Aud i is not a pure offroad ve hi­
cle . It was not built for driving under extreme
conditions, e .g . for trips that are in the nature
of an expedition .
D riv e only on roads and offro ad sections
which match the des ign of your vehicle and
your abil it ie s as a driver . Ne ver take ri sks!
Before dri ving offroad
- Check the engine oi l level, tire pressure,
coolant leve l, and the fluid level in the w ind­
shield washer reservo ir.
- Stow luggage items and other objects in the
lu ggage compartment, and secure them
against slid ing around .
After driv ing offroad
- After trips offroad, remove any twigs and other foreign objects from the grill, the un­
derbody and the wheels. Pay specia l atten­
t ion to fore ign objects (stones) which have
become lodged in the tire tread.
- Clean the body and the vehicle unders ide,
and inspect the veh icle for possible damage.
- Clean dirty windows, headlamp lenses, rear
lights, and license plates.
- Perform a brake check (particu larly after
trave lling through water) .
A WARNING
- Drive especially attentive ly and plan
ahead in difficult road conditions and
w hen offroad . Excess ive speed or incor-
-
Driving off road 209
rect maneuvers can cause injuries and
damage to the vehicle.
- Always adapt your speed and driving
style to road, offroad, traff ic, and weath­
er conditions. Drive especially slowly off­
road when your v iew is restricted.
- Please be aware that in ESC offroad
mode, particularly on a smooth and slip­
pery road, the wheels may have an in­
creased tendency to spin and the vehicle
may break away - danger of skidding!
- Stability is limited in the ESC offroad mode.
@) For the sake of the environment
Avoid damage to the environment and re­
spect nature .
(D Tips
Only drive where it is permitted and stay
on marked roads and paths.

236 Check ing and filling
Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, 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 he lp 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
repairs .
At the time of pr int ing , engine o ils available in
the U .S . and Canada that meet the exacting
specifi cations of Audi oi l standard VW 502 00
a re synthetic engine oils. This does not mean,
however, that every syn thetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the format ion of harmful de ­
posits use only oi l with the fo llowing specifi­
cations printed on the oil container :
Audi oil standard VW 502 00
O il container labe ls may carry the specif ica ­
tion s ingly or in comb inat ion with other des ig­
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis­
cosity. The proper viscosity grade oil for your
engine depends on cl imactic or seasonal con­
d itions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem ­
pe ratu re ranges for normal driving conditions .
However, if eng ine o il viscos ity grade SA E
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
specif ications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an ext ra quart (
li te r) of oil that exp ress ly con forms to the
VW 502 00 spec ification, in case you have to
top
off the oil while on the road.
Only if the ba r of the o il level indica tor is near
" Mi n" - and no oil that express ly conforms to
Audi o il standard VW 502 00 specifications is
available - may you top
off w ith a high quality
engine oil, preferably synthetic-based, that
meets ACEA A3 or API SM spec ificat ions, but
even then, on ly in viscosity grades SAE
SW-40, SAE SW-30, or SAE OW-40 . Howeve r,
during the entire time between o il change in­
te rva ls , never top
off with more than a total
of 0 .5 qt/liter engine oil t hat does not con­
f orm to Audi oil specification VW 502 00 .
For more information about eng ine oi l that
has been approved for your ve hicle, please
contac t either yo ur autho riz ed Aud i deale r or
Audi C ustome r Re lations at 1 (800) 822-2834
or v isit our web site at www .audiusa.com or
www.audicanada.ca . Here you wi ll also find a
c u rrent list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
T he eng ine o il and o il fil ter m ust be changed
accord ing to the mileage (k ilometers) and
time intervals specified in your ve hicle's War ­
ranty
& Maintenance booklet . Do not exceed
these interva ls - harmful deposits from old
engine oil can reduce eng ine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter­
vals is so very important because the lubricat­
ing propert ies of oil decrease gradually d uring
normal veh icle use. If you are not sure when
you have your oil changed, ask your author ­
ized Audi Se rv ice Adv isor.
Under some circumstances the engine oil
shou ld even be changed more frequent ly.
Change oil more often if you drive most ly
sho rt distances, operate the ve hicle in dusty
areas o r most ly unde r stop-and-go traff ic con­
ditions, o r when you use your vehi cle where
temperatu res s tay be low freezing point for
l ong periods .

240 Checking and filling
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 water and the manufacturer's gly­
col-based coolant additive Gl3 ant ifreeze
with anticorros ion add itives (SO% for USA
models; 60% for Canadian models). This mix­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration of the coo l­
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 veh i­
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- - 31 °F ( - 35°() USA
- - 40°F ( - 40°() Canada .
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c:> &. in Working in the engine
compartment on page 233.
- Before winter sets in, have the coolant
checked to see if the coolant addit ive in
your vehicle is sufficient to meet the cli­
mate cond itions. This is especially impor­
tant if you live in a region where the w in- ter
is extreme ly 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 Gl2++ or Gl3 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 ca use 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 .
Add ing 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.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .

(D Note
- Coolant pollutes the env ironment and
could cause an engine fire . Excess coo l-
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze¢
page 240 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself
The radiator fan is driven by the engine via the
V-be lt . The viscous clutch regulates the speed
of the fan accord ing to t he temperature of the
coolant.
An auxiliary electric radiator fan* switches on
a nd off depending on coolant temperature
and other ve hicle operating conditions.
After you switch the engine off, the auxiliary
fan can cont inue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢&. , if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the veh icle is parked in intense sunlight.
_&. WARNING
- To reduce the r isk of personal injury nev­
er to uch the radiator fa n. -
The a uxiliary electric fan is temperat ure
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on a u­
tomatically when the engine coolant reaches a certai n temperature and will
continue to ru n until the coolant temper­
ature drops.

(D Tips
Where snow chains are mandatory oncer ­
tain roads, this norma lly also applies to
veh icles with all-whee l dr ive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit ­
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model<=>

A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of

torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing

Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
tions . Ask your authorized Aud i dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s­
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 2 54, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.
