ESP AUDI Q7 2014 Owner´s Manual

-Never get back into your vehicle while re­
fueling. If in exceptional circumstances
you must get back in your vehicle while refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Stat ic electricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel container.
- For your safety, we strongly recommend
that you do not trave l w ith a portab le
fuel container in your vehicle. The con­
tainer, full or empty may leak and cou ld
cause a fire, especia lly in a crash .
-If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for examp le, in the luggage compart­
ment, or on the trunk). Static electr ici­
ty can bui ld up while fi lling and can ig­
nite fuel vapors causing a fire.
- Always p lace a portable fuel container
on the ground before filling.
-Always keep the filler nozzle complete­
ly inside the portable container before
and during filling .
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. This will
he lp prevent static electricity from dis­
charging and cause a fire.
- Never spill fuel inside the vehicle or
luggage compartment. Fue l vapors are
h ighly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers.
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852 -86).
Fuel supply and filling your fuel tank 253
@ Note
If any fuel has spilled onto the car, it
shou ld be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correct ly operated nozzle
switches off automat ically for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out. In
addition, the expansion space in the fuel
tank w ill be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
0) Tips
-Running your eng ine while refuelling
may cause vapors to escape or even
cause fuel to sp ill out of the tank . Th is
would then shut off the fuel nozzle be­
fore the tank is ful l.
- Do not refuel your vehicle with the igni­
tion turned on. The fuel gauge may oth­
erwise not indicate the correct f uel level
after refuelling.
- Diesel vehicles* are equipped with a d ie­
sel misfueling protector . It allows the
vehicle to be fueled only with a diese l
fuel pump nozzle. A worn or damaged
nozzle or a nozzle that is too small may
not be able to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before inserting it in the fuel
filler neck, use a different fuel pump or
see your authorized Aud i dea ler or au­
thorized repair facility for assistance. •

with the surround ing vehicle body parts.
- If you notice while driv ing that the hood
is not secured prope rly, stop at once and
close it .
Working in the engine compartment
Be especially careful whenever you work in
the engine compartment.
Whene ver you must perform any wo rk in the
eng ine compartment, for e xample checking
and filling different fluids, there is a risk of injury, burns and accidents. To pr event per­
sonal injury always observe the following

A WARNING ~
To help avoid injury, befo re yo u check any­
thing under the hood:
- Tu rn off the engi ne.
- Remove the igni tion key.

For year-round driv ing, antifreeze is added at
the factory for temperatures down to:
- - 31 °F (- 35 °C) USA
- - 40 °F ( - 40 °C) Canada .
If you mus t add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distilled water is recommended .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 257.
(D Note
-Before winter sets in, have the coolant
checked to see if the coolant additive in
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 Gl2++ 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.

the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
¢ page 259 .
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 32 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­ ommend you check the coolant level from
time to time .

Disconne cting the batt ery t erminals
Some vehicle functions (power w indow regu ­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicle s not driven fo r lo ng period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off .
This reduces energy consumption and main­
tains starting capab ility over a longer per iod
¢ page 229 .
Take into consideration that when you unlock
your vehicle, some convenience functions,
such as the inter ior lights or the power seat
adjustment, may not be available . The con­
ve nience funct ions w ill be available again
when yo u turn on the ignition and start the
engine.
Winter op eration
During the winter months, battery capacity
tends to decrease as tempe ratures d rop . This
i s because more powe r is also consumed while
start ing, and the headl ights, rea r window de ­
fogger, etc., are used more often.
Avo id unnecessary power consumption, par­
ticularly in c ity t raffic or when t rave ling on ly
short d istances. Let you r autho rized Aud i
dealer check the capacity of the vehicle bat­
tery before winter sets in ¢
page 270. A we ll
charged battery wi ll not only prevent starting
prob lems when the weather is cold, but will
also last longer .
If your vehicle is left standing for severa l
weeks at extremely low temperat ures, the
veh icle battery should be removed and
stored where it will not freeze. This will
prevent it from bei ng damaged and hav ing
to be replaced.

General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . T ires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tively small patch of rubber on eac h tire that
assures that a ll- important contact between
you, you r vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han­
d le, avoiding damage from road hazards and
r eg ularly inspec ting t ires for damage i nclud­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
Avoiding damage If you have to d rive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re­
i nstall them .
When removed, the whee ls or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .

New tires
New tir es have to be broken in ¢ & .
The tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread

Hidden damage
Damage to tires and r ims is ofte n not readily
visible . If you notice unusual v ib rat io n or the
vehicle p ulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au­
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar­
rows on the s idewa ll, that po int in the direc­
tion the t ire is designed to rotate. You mus t
f ol low the specified di rection o f rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information ¢
page 301.
A WARNING
New tires or t ires that are o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in. To reduce the r isk of losing
control, a co llision and ser ious personal
in ju ries, d rive with special ca re fo r the
fi rst 350 m iles ( 560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowout and sudden de­
fl ation, c ras hes and se riou s personal in­
juries . Have wo rn or damaged t ires re­
placed immediate ly.
- Ti res age even if they are not being used
and can fai l sudden ly, especially at hig h
spee ds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

274 T ire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.

using winter tires during the winter
months . Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very co ld tem­
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un­

p ill ar
Tire pressure genera lly refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nte rna­
tional measur ing unit and in pounds pe r
squa re i nch (PSI). Tire pressure is based in
part on the vehicle 's design and load limi t -
the greatest amount of weight that the vehi­ cle can carry safe ly and the t ire size . The prop­
er tire pressure is frequent ly referred to as the
"recommended cold tire inflation pressure."
A ir in the tires expands when the tire heats up
because of internal friction when it flexes in
use . The tire p ressu re is higher when the tire
has warmed up than when it is "cold ."
It is the
i nflat ion p ressure i n a "cold " tire that counts.
Therefo re, you shou ld neve r let air out of a
warm tire to ma tch "cold tire infla tion pres­
sure" recommendations. The t ires wo uld then
be underinflated and could fail suddenly .
M aintaining p roper t ire press ure is one of the
most impor tant things you can do to he lp
avoid sudden tire failure. Underinflated t ires
are a ma jo r cause of s udden tire failure . Keep·
ing tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

The recommended tire pressures for your Audi
depend on the kind of tires on your ve hicle

of luggage you w ill be transporti ng.
The tire pressure label is located on the driv­

The correct tire pressure for the spare wheel is
located on a label on the driver's side 8-p illar .
Because technical changes may be made to
vehicle equipment dur ing the model year, al­
ways compare the tire size designation on the
tire pressure label on your vehicle w ith the
tires on your vehicle. Make sure that the tire
size info rmation on the vehicle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
l ongs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of yo ur pas­
sengers also depends on making s ure that load
limits are not exceeded . Veh icle load in­
cludes everybody and eve ryth ing in and on the
vehicle. These load limits are techn ica lly refer­
red to as the veh icle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle We ight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two ax les.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side 8-pillar . The tire pressure label on
your Audi lists the maximum combined
weight of all of the occupants and luggage or
other cargo that the veh icle can carry . For the

The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always befo re starting a journey. Do not
forget to check the tire pressure for the spare wheel.
When should I ad ju st th e tire p re ss ures?
Adj ust the tire p ressure to the load you are
carry ing . After chang ing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then
store the new tire press ures in the tir e pres­
sure monito ring system

A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death .
- When the warn ing symbol
[I] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the hand ling of the vehicle and
stopping abi lity.
- I nco rrect tire pressures a nd/or underin­
f lation can a lso lead to sudden t ire fail­
ure, including a blowout and sudden de­
flation, ca using loss of vehicle contro l.
- The drive r is responsible for the correc t
tire pressures for all tires on the veh icle.
The applicable pressure values are locat ­
ed on a sticker on the driver's side B -pil­
lar.
- On ly when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure mon itoring system can work cor­
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re press ure monitor­
ing system.
- Always inflate t ires to the recommended
and correct t ire p ressure before dr iv ing
off.
- Driving with underinf lated tires bend
mo re, letting them get too hot resulting
in tread sepa ration, s udde n tire failure
and loss of cont ro l.
- E xcessive speed and/overloadi ng can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.
- I f the tire pressure is too low or too high,
the t ires will wear prema turely and the
vehicle wi ll not handle well. ..,
