AUDI Q7 2013 Owner´s Manual

-Always follow the instructions provided
by the manufacturer of the ch ild re­
straint you intend to install in your veh i­
cle .
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instruc­
t ions req uire the top tether strap to be
used.
- Improper use of ch ild restra int LATCH
lower anchorage points can lead to injury
in a collision. The LA TCH lower anchorage
points are designed to withstand only
those loads imposed by correctly fitted
child restraints.
- Never mount two child restraint systems
on one LATCH lower anchorage point.
- Never secure or attach any luggag e or
other item to the LATCH lower anchorag­
es .
{i) Tips
-In Canada, the terms "top tether" with
"lowe r universal anchorages" (or "lower
universal anchorage bars") are used to
desc ribe the system .
- In other countries, the term "ISOFIX" is
us ed to describe the lower anchorages.

Lower anchorages secure the child restraint in
the seat without using the vehicle's safety
belts. Anchorages provide a secure and easy­
to-use attachment and minimi ze the possibili-
ty of improper child restraint installation. .,..

220 Child Safe ty
A ll child restraints man ufactured after Sep­
tember 1, 2002, must have lower anchorage
attachments for the
LATCH system.
Remember that the lower anchorage points
are on ly intended for installation and attach­
ment of child restraints specifically certified
for use w ith
LATCH l ower anchorages . Child
restra ints that are not equipped with the tow­
er anchorage attachments can still be instal­ led in compliance with the ch ild restra int
manufacturer's instruct ions on using vehicle
safety belts.
A WARNING
Improper use of LATCH lower anchorages
can ca use serio us pe rsonal injury in an ac­
cident.
- Always carefully follow the ch ild re­
strain ts manufac turer's instruct io ns for
proper installation of the child restraint
and proper use of the lower anchorages
or safety belts in your vehicle .
- Never secure o r attach any l uggage or
ot her items to the
LATCH lower ancho­
rages.
- Always read and heed the important in­
formation about child restraints in this

t ures per sea t snaps into place.
Removing the guidance fixtures
.,. Remove the ch ild restraint according the
child restraint manufacture r's instructions .
.,. Push down on the seat cus hion so that the
lowe r ancho rages are v is ible.
.,. Pull off the gu idance fixtures from the low ­
er ancho rages .
.,. Always remove the guidance fixtures and
keep them in a safe p lace when not in use .
You may find it easier to install c hild re­
straints equ ipped with hooks attached to
straps witho ut the g uidance fixtures in place.
If this is the case, remove the guidance fix­
tures by pulling them off the anchorages. However, the guidance fixtures can help you
to locate the
LATCH anchorages . ..,.

_& WARNING
Improper use of tether anchorages or low­
er anchorages can cause serious personal
injury in a crash.
- Always carefully follow the child re­
straint manufacturer's instructions for
proper installation and use of child re­
straint systems.
- Never use the
LATCH or tether anchorag­
es to attach safety belts or other kinds of
occupant restraints.
- Child restraint tether attachments and
lower attachments are only designed to
secure a child restraint that has been
equipped to use these anchorages.
- Tether anchorages and lower anchorages
are designed to withstand only those
loads imposed by correctly fitted child
restraints. Under no circumstances can
they be used safely for adult or child
safety belts or harnesses.
- Never mount more than one child re­
straint to a single tether or to a lower an­
chorage point. Attaching two child re­
straints to a single anchorage point can
cause the anchorage to fail and cause se­
rious personal injury in a crash.
(D Note
-Remove the guidance fixtures before
folding the rear seatback to prevent
damaging the seat cushion.
- If you leave the guidance fixtures instal­
led for several days, they could leave a
mark on the upholstery on the seat cush­
ion and backrest in the area that the
guidance fixtures were installed. The up­
holstery would also be permanently
stretched around the guidance fixtures.
This applies especially to leather seats.

c> fig . 229 .
A tether is a stra ight or V-shaped strap that
attaches the top part of a ch ild restra int to
special anchorage po ints in the vehicle .
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a
crash, in order to help reduce the risk of head
injury that could be caused by striking t he ve­
hicle inte rior .
Forward facing child restraints manufactured
after September 1, 1999, are required by U.S .
federa l regu lations to comply with new child
head movement perfo rmance requ irements .
T hese new perfo rma nce req uirements make a
tether nece ssary on most new child safety
seats .
,&_ WARNING
-= -Improper installation of child restraints
will increase the risk of injury and death i n
a crash.
- Always follow the instructions provided
by the manufacturer of the child re-
straint you intend to install in your Audi. ..,_

-Improper use of child restra int anchors
(incl uding tether anchors) can lead to in­
jury in a co llision. The anchors are de­
signed to withstand only those loads im­
posed by correctly fitted ch ild restraints .
- Never mount two child restraint systems
on one LATCH lower anchor po int.
- Never attach two child restraint systems
to one tether strap or tether anchorage.
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use ch ild restra int tether ancho­
rages to secure safety belts or other
kinds of occupant restra ints.
- Never secure or attach any luggage or
other items to t he LATCH lower ancho­
rages or to the tether anchors.
- If a tether or other strap is used to at­
tac h a child restraint to the fro nt passen­
ger seat, make sure that it is not so
t ight, that it causes the we ight-sensing
mat to measu re mo re weight than is ac­
t ual ly on the seat.

in the area whe re the tether strap was in­
stalled. The uphols tery would a lso be per­
manently stretched around the tether
strap . This applies especially to leather
seats .
Using tether straps on rearward-facing
child restraints
Currently , few rear -facing child restraint sys­
tems come with a tether . P lease read and
heed the child restraint system manufactur­
e r's instructions caref ully to determine how to
p roperly insta ll the tethe r.
& WARNING
A child in a rearward -facing child safety
seat insta lled on the front passenger seat
w ill be seriously injured and can be ki lled if
the front a irbag inflates - even with an Ad­
vanced Airbag System.
- The inflating airbag will hit the child safety seat or infant carrier with great
force and w ill smash the ch ild safety seat
and child against the backrest, center
armrest, or door .
- A tight tether or other strap on a rear­
ward-facing child restra int attached to
the front passenger seat can put too much pressure on the weight-mat in the
seat and register a heavier weigh t in the
Advanced Airbag System. The heav ier weight registered can make the system
work as though an adult were on the seat
and deploy the Advanced Airbag when it must be suppressed causing ser ious or
even fatal injury to the ch ild.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptional c ircumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately insta ll the rear-fac ing ch ild
safety seat in a rear seating position and have the airbag system inspected by your
Audi dea ler.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDRs are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for example, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Intelligent technology 225
Electronic Stabilization
Control (ESC)
General information
The ESC improves the vehicle stability.
. ..---------..
------- -
Fig. 232 Center console with ESC sw itch
ESC is designed to help you maintain vehicle
control in situations where the car approaches
the limits of "grip", especially when accelerat­
ing and cornering. ESC reduces the risk of
skidding and improves stability under all road
condit ions .
The system operates across the entire speed range in combination with the ABS system. If
the Anti-Lock Brake System (ABS) malfunc­
tions, the ESC will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic
Differential Lock (EDL) and the Anti-Slip Regu­
lation System (ASR) are integrated in the Elec­
tronic Stabilization Control. In addition to the
data prov ided by these functions, the ESC con­
trol unit requires additional measurement da­
ta provided by high performance sensors. The
rotational speed of the vehicle about its verti­
cal axis, vehicle acceleration in the fore-and­
aft and lateral directions, the brake pressure and the steering angle are all measured.
T he direction in wh ich the driver wishes to
travel is determined with the aid of the steer­
ing angle and vehicle speed and is continually
compared with the actual behavior of the ve­
hicle. If the two do not match, for example,
when the vehicle starts hydroplaning on a wet
road, ESC will automatically brake the appro-
priate wheel to correct the problem. ..,_
•
•

226 Intellig ent technol ogy
The vehicle is then stabilized by the forces act­
ing on the whee l during braking. If the vehicle
is
oversteering (rear tends to sk id out of the
turn), the brakes are ma inly applied on the
wheel that is on the outside of the curve. In
the case of a vehicle that is
understeering
(tendency to slide out of the curve), the
brakes are applied as needed on the whee l
that is on the ins ide of the curve or addit ional­
l y on the o ther wheels. An acoustic s ignal indi­
cates when ESC b rake app lication cuts in
¢ A .
The system operates across the entire speed
range in combination with the ABS system
¢ page 229. If the Anti-Lock Brake System
(ABS) malfunctions, the ESC wi ll be out of ac­
tion as well .
Activating
When you turn on the engine, ESC w ill auto­
mat ica lly be act ivated and will perform a se lf­
test. As soon as the test is comp leted, the sys­
tem is in normal operating mode.
Offroad mod e
ESC should normally be ope rated in normal
mode because this ensures maximum vehicle
stability. If necessary, you can act ivate the
ESC offroad mode by pressing the but to n
¢ fig . 232 to obtain maximum traction and
braking ability when driving
off paved roads at
l ow speeds. In ESC offroad mode, the indica­
tor light
Ii) ill uminates and the message Sta ­
b ilization control (E S C): Offr oad . Wa rning !
R estric te d stabilit y
appears br iefly in the dis­
p lay .
The ESC offroad mode can be useful in the fo l­
low ing except ional situations when slip or a
h ighly effective differential locking function is
des irable . Examp les:
- when driving with tire chains,
- when driving in deep snow or on loose
ground,
- when driving on uneven surfaces with the
whee ls severe ly unloaded (articulation), and
- when rocking the vehicle loose after it has
become stuck . When the
unusual situation is past, you
sho uld shift back to the norma l ESC operating
mode by pushing the button again . The mes­
sage
S ta b ilizat ion cont rol (ES C): O n then ap­
pears briefly in the display.
H ill desc ent control
The hill descent control is switched on in ESC
offroad mode . When slowly descending steep
gradients on loose ground or when the axles
are articulated, hill descent control provides ass istance by automatically apply ing the
brakes to keep vehicle speed constant. The ve ­
hicle is also rendered easier to steer by selec­
t ive d istr ibut ion of braking force. Hill descent
control intervenes when:
- the acce lerator pedal is not pressed,
- the vehicle is travelling less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavior indicates loose ground or
conditions with poor adhesion (e .g. also axle
art iculation).
Hill descent contro l operates both d riving for­
ward and in reverse. Active hill descent con­
tro l is deactivated by pressing the accelerator
pedal until the condit ions for activation al­
ready listed are met again .
A WARNING
--
- The Electronic Stabilization Contro l is
neverthe less s ubject to the laws of phys­
ics. It is part icularly important to pay at­
tention to this fact on wet and slippe ry
roads . It i s therefore important that you
always adapt your dr iving to the cond i­
tion of the road and traffic conditions . Do
not a llow the increased safety provided
by the E lectronic Stabilization Contro l
system to lull you into accepting addi­
tional safety risks .
- Please be aware that in ESC offroad
mode, particularly on a smooth and s lip­
pe ry road, the wheels may have an in­
creased tendency to sp in and the vehicle
may b reak away - dange r of skidding!
~

-Stability is limited in the ESC offroad
mode.
Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels .
General notes
The electronic differentia l lock (EDL) helps the
car to start movi ng, accelerate and climb a
gradient on surfaces providing poor or almost
no grip. Without EDL, this would be difficult,
if not impossible.
H ow the system works
The ED L opera tes automatically. It monitors
the rotat iona l speed of wheels w ith the help
of the ABS sensors¢
page 229. If a noticea­
b le
slip is detected at the wheels (e .g. on slip ­
pery ground
on one side), the spinning whee ls
are braked and power is transferred to the
other wheels. This is done up to a speed of
about
60 mph (100 km/h) . Noises from the
brake system s ignal that wheel sp in is being
controlled.
Dri ving off
When driving off, always be sure to keep road
conditions in mind as you accelerate. If one
drive wheel spins because it is on a surface
w ith less gr ip, apply
plenty of throttle until
the car starts to move.
O verheating of br akes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads on this wheel, the EDL cuts out tempo­
rarily . T he vehicle remains operational and be­
haves in the same way as a veh icle w ithout
E DL.
As soon as the brake has cooled down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be carefu l
when depressing the acce le rator pedal.
Int ellig ent technolog y 22 7
Even with the EDL working, the drive
wheels can spin and red uce your ab ility
to control your car. Risk of crash!
- The increased safety afforded by EDL
does not mean that you can take safety
risks. Always adapt your driving style to
the road condit ions and traffic situation .
(D Tips
If a fault occurs in the ABS, the EDL is also
not functioning. This is ind icated by the
ABS warning light¢
page 18.
Anti-Slip Regulation System (ASR )
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating .
General note s
The Anti-Slip Regu lation System (ASR) is inte­
grated in the Electronic Stabilization Control
(ESC). When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning
by adjust ing the engine power to match the
amount of grip available from the road sur­
face .
How the sy stem works
ASR performs automat ically, i.e. without the
driver's intervention. With the aid of the ABS
sensors ¢
page 229, ASR monito rs the speed
of the dr iven wheels .
If the wheels start to
spin, engine torque is red uced automat ically
unt il the t ires find enough grip to lock onto
the ro ad surface. The system is active across
the entire speed range.
T he ASR works in conjunction with the ABS. If
a malfunc tion s hou ld occu r in the ABS, the
ASR wi ll also be out of act io n.
A WARNING ~
The increased safety affo rded by ASR does
not mean that you can take safety risks.
A lways adapt your driving sty le to the road
conditions and traffic situation.
Ill--
•
•

228 Intelligent technology
To ensure that the ASR works properly, all
four wheels must be fitted with identical
tires. Any differences in rolling rad ius of
the t ires can cause the system to reduce
engine power when this is not desired. See
also¢
page 291, New tires and replacing
tires and wheels.
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wea r, depending la rgely on operat­
ing cond itions and dr iv ing habits
Q ,& . On
vehicles that are either driven mostly in stop­
and -go city traffic or are driven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the
Warranty & Maintenance booklet . Failure
to have your brake pads inspected can result
in reduced brake performance .
On steep slopes, you shou ld use the braking
effect of the engine. This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down continuously . Pump the brakes at inter­
va ls.
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for examp le, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads. A
few careful brake applications should dry off
the brake pads o r remove any ice coatings.
When you are driving at higher speeds with
the w indshield wipers on, the brake pads will
brief ly touch the brake discs in regular inter- vals so as
to improve reaction time when brak ­
ing on wet surfaces . You, the driver, will not
notice anything.
T he effect iveness of the brakes can be reduced
when the vehicle is driven on a sa lt-covered
road and the brakes are not used . Here too,
you should clean off accumulated sa lt coating
from brake discs and pads w ith a few careful
applications of the brake¢,&.
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regu larly or
only for short trips with litt le use of the
brakes.
If the brakes are not used frequently, or if cor­
rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed
c> ,& .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ir cuits may have fa iled
c> ,& .
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
l evel is monitored electronically .
Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spect ion
c> page 304, Changing a wheel.
A WARNING
-- You shou ld perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Othe r road users must not be put at risk -
you may cause an accident!
