2014 AUDI Q7 Owner´s Manual

& WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death .
- Carrying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in­ crease the risk of a loss of veh icle con­
trol.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
tro l and a crash .
- Always make sure that the tota l load be­
ing transported -including the we ight of
a tra ile r hi tch and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cl e Weight Rating.
& WARNING
- Incorre ct tire pressures and/or underin­
fla tion can lead to a serious o r fatal acci­
dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle .
- Incorre ct tire pressures and/or underin­
fla tion can also lead to sudden tire fa il­
ure, incl uding a blowo ut and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
-
The correct tire pressure for the tires original ­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­ lar.
The recommended tire pressures are on the
tire pressure label and in the tab le
c:::> page 277, Cold tire inflation pressure .Th is
means that the pressure must be checked and
adjusted when the tire has not been driven for more than a couple of m iles (kilometers) at
low speeds during the p revious three hours .
Tires an d wheel s 2 79
Air in the tires expands when the tire heats up
as a result of internal friction as it flexes in
u se . The tire pressure is h igher when the tire
has warmed up than when it is "cold."
It is the inflation pressure in a "co ld" t ire that
counts . The refore, you should never let air o ut
of a warm tire to match "Cold t ire in flat ion
pressure" recommendat ions ¢
page 277 . The
tires wo uld then be underinf lated and could
fail suddenly .
The t ire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
maximum capacity for the new, orig inal
equipment tires that were on your ve hicle at
the time it was ma nufactured . For the loca­
tion of the labe l
¢page 277, fig . 249 .
Most tires lose air naturally over t ime . They
can a lso lose some air if you drive over a pot ­
hole or hit a curb while park ing.
It is usually
not poss ible to see whethe r the rad ia l tires
u sed today are under inflated just by loo kin g
at them.
T herefo re, be su re to check t ire pressu res at
l east once a mo nth and a lways befo re go ing
o n a long tr ip. Ma ke s ure to ta ke t he number
of peop le and the amount of luggage in to ac­
count when ad justing tire pressu re for a trip -
even one that yo u wo uld not conside r to be
"long." See¢
page 281, Tires and vehicle
load limits
for more important information .
A lways use an acc ura te tire pressu re ga uge
when checking and adj usting inf lation pres ­
s ur es . Check a ll of the tires and be sure not to
forget the spare tire. If the pressure in any t ire
is too high when the tire is "cold," let a ir o ut
of the t ire s low ly w ith the edge of the tire
gauge and keep checking the pressure until
yo u reach the pressure that is correct for the
load (passengers and luggage) and k ind of
driv ing you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure i n the cold
t ir e and the pressu re you need and add the air
t h at you need to reach the cor re ct pressure for
the ve hicle load (passengers and luggage) for
the tires on your vehi cle as listed on the on •

of driving yo u plan to do .
Neve r e xcee d the m ax imum inflati on pres­
s u re list e d on th e tir e s ide wall f or a ny r ea­
s on.
Remember that the vehicle manufacturer, not
the tire manufacturer , determ ines the co rrect
tire pressure for the t ires on your veh icle .
It is important to check the tire pressure when
the tires a re cold .
- Read the required t ire pres sure from the tire
pressure label. The ti re pressure label is lo­
cated on the driver's side 8-p illar . The t ire
pressure label lists the recommended cold
t ire inflat ion p ressu res for the veh icle at its
maximum capacity we ight and the tires that
were on you r vehicle at the time it was man­
ufactured . For recommended tire pressures
for normal load condit ions, please see chap­
ter
c:> page 2 77.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the a ir pressure gauge on the valve.
- T he tire pressures should on ly be checked
and adjusted when the tires are cold. The
s li ghtly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying .
- Reinsta ll the va lve stem cap on the valve.
When should I check the tire pressur e?
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
c:> page 293.
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. ..,

-If the ti re is not flat and y ou do not have
to change a wheel immed iate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Dr iving without va lve stem caps can cause
damage to the t ire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secu re ly
mounted on the va lve.
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight t hat any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the ve hicle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
load limits a re tech nica lly referred to as the
ve hicle's
Gross Veh icle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
ve hicle, all factory installed accessories, a full
tank of f uel, oil, coo lant and othe r fluids plus
max imum load. The maximum load includes
the number o f passenger s that the ve hicl e is
intended to carry ("se ating capacity") w it h an
assumed weig ht o f 150 lbs (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve­
h icle. If you tow a trailer, the weight of the
trailer hitch and the tong ue weight of the
Tire s an d wheel s 281
loaded tra ile r must be included as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating (" GAWR") is
the max imum load th at can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are l iste d on the
s af ety comp liance s tic ke r la bel lo cated on the
driver's side 8 -pillar . Your Audi has 5 seating
positions, 2 in the front and 3 in the rear fo r
total seating capacity of 5. On vehicles with
s ix seats*, your vehicle has two front seats,
two seats in the second row seat ing and two
seats in the th ird row seati ng. On veh icles
with seven seats*, your vehicle has two front
seats, t hree seats in the second row s eating
and two seats in t he third row seating. Ea ch
seat ing pos itio n has a se at belt
~page 174,
Safety be lts .
The fact that ther e is a n upper limit to you r
vehicle's G ross Vehicle Weigh t Rati ng means
that the to tal weig ht of whatever is bei ng car­
ried in the vehicle ( in cl ud ing the weight of a
trailer hitch and the tongue weight of the l oa ded trai le r) is limite d. The more passen­
gers in the vehicle or passengers who are heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage.
The tire pressure label on your Audi also lists
the max imum combined weight of all of the
occupants and luggage or other cargo that
t h e ve hicle can carry. Fo r the locat ion of the

A WARNING
Overloading a veh icl e can cause loss of ve­
h icl e cont ro l, a crash or o ther accide nt, se­
rio us pe rson al inj ury, a nd eve n death .
- Ca rrying more we ight tha n your ve hicle

282 Tires and wheels
-The brakes on a vehicle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi­
cle's placard (tire inflation pressure label)
¢ page 2 77,
fig. 249.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle. 3
. Subtract the combined
weight of the driver and pas­ sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢page 277, fig. 249.
4. The resulting figure equals the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five
150
lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is
650 lbs. (1400-7 50
(5 X 150) = 650 lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­ duces the available cargo
and luggage load capacity of
your vehicle. ..,

.,.Check the tire sidewall
(i=> page 284, fig. 253) to de­
termine the designated load rating for a specific tire.
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.
Fig. 251 Tire tread: tread wear indicators (TWI)
Fig. 252 Rotating tires for more even wear
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig. 251 running across the tread. Depend­
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear indicators . Worn tires must be replaced.
Different figures may apply in other countries
c::> &. .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden tire blow-out . For this
Tires and wheels 283
reason , tire pressure must be checked at least
once a month
c::> page 2 79.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing:
- Tire rotation intervals may differ from the
vehicle service intervals outlined in your
Warranty & Maintenance booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points ; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals.
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pared to all-wheel drive (q uattro).
- Please rotate tires as shown
c::> fig. 252.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 301.
Wheel balancing
The wheels on new vehicles are balanced .
However, various situations during everyday
driving can cause them to become unbal­ anced, resulting in vibrations you can usually
feel through the steering wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi­
cle.
If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.

284 Tires and wheels
All-wheel drive
Vehicles with quattro must always have tires
of the same size , construction and tread type.
For details see Qpage 228.
~ WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage , such as grease, oil, gasoline
and brake fluid away from tires .
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you a re 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 tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .

Always buy rep lacement radial tires that have
the same specifications as the t ires approved
for your ve hicle by Audi. Replacement tires
must always have the same load rating speci ­
fication as the original equipment or approved
optional tires listed in the table

U.S. DOT Tire Identification Number (TIN)
and tire manufacture date
This is the tire's "serial number". It begins
with the letters "DOT" and indicates that the
tire meets all federal standards. The next two
numbers or letters indicate the plant where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
For example, the numbers 2213 mean that
the tire was produced in the 22nd wee k of
2013. The other numbers are mar keting co­
des that may or may not be used by the tire
manufacturer . This information is used to con­
tact consumers if a tire defect requires a re­
call.
Audi Original tire
Tires with the identification "AO" or "RO" have
been specia lly matched with your Audi . We
recommend using only these tires because
they meet the highest standards regard ing
safety and driving character istics when used
correctly. Your authorized Audi dealer will
gladly provide you with more information.
Tire ply composit ion and materials used
The number of plies indicates the number of
l ayers of rubber-coated fabric in the tire. In

genera l, the greater the number of plies, the
more weight a tire can support. Tire manufac­
turers also must indicate the materials in the
t ir e, which include steel, nylon, po lyester, and
others.
Maximum Load Rating
This number ind icates the maximum load in
kilograms and pounds that can be carried by
the tire.

.&, WARNING ~ -
-Using incorrect or unmatched tires and/
or wheels or improper tire and wheel
comb inat ions can lead to loss of control,
coll is ion and serious personal injury.
-Always use t ires, rims and whee l bolts
that meet the specifications of original
factory- installed tires or other combina­
tions that have been specifically ap­
proved by the vehicle manufacturer.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergen cy
and then with special care and at lower
speeds.
- Never mount used tires on your 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 tire fa ilure
and loss of vehicle control.
