2013 AUDI Q5 brake

-Never mount used tires on yo ur vehicle if
yo u 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 failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

A 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 your 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 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 causing loss of con­
trol and a crash .
- Always make sure that the total load be­
ing transported -including the we ight of
a tra iler hitch and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cle Weight Rating.
A WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious o r fatal acci­
dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wea r and can
affect the handling of the vehicle .
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowo ut and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
-
The correct tire pressure for the tires originol­
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 labe l and in the tab le
c:::> page 252, Cold tire inflation pressure .This
means that the pressure must be checked and
adjusted when the tire has not been driven for more than a couple of m iles (k ilometers) at
low speeds during the p revious three hours . Air in the tires expands when the tire heats up
as a result of interna l 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" tire that
counts . Therefore, you should never let air out
of a warm tire to match "Cold t ire inflat ion
pressure" recommendat ions
c:::> page 252 . The
t ires wou ld then be underinflated and could
fail suddenly .
The tire 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 vehicle at
the time it was manufactured . Fo r the loca­
t ion of the labe l
c:::>page 252, fig . 203 .
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 possible to see whether the rad ia l tires
used today are underinflated jus t by looki ng
at them.
T he refo re, be sure to check t ire p ressures at
least once a month and always before going
o n a long trip. Ma ke sure to take the numbe r
of peop le and the amou nt o f luggage into ac­
count when adjust ing tire pressu re for a trip -
even one that yo u wo uld not consider to be
" long." See
c:::> page 256, Tires and vehicle
load limits
for more important information .
Always use an ac curate tire p ress ure ga uge
when checking and adj usting inflation pres­
s u res . 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 air out
of the tire s low ly w ith the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is co rrect fo r the
load (passengers and luggage) and k ind of
dr iv ing you plan to do.
If the pressure in any tire is too low, note the
difference between the p ressure in the co ld
t ire and the pressure you need and add the air
t h at you need to reach the cor rect pressure for
t h e ve hicl e load (passengers and luggage) for
the tires on your vehicle as listed on the on

256 Tire s and wheel s
-If the tire is not flat and you do not have
to change a wheel immed iately, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required .
(D Note
Driving without va lve stem caps can cause
damage to the t ire valves . To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the
valve .
@) For the sake of the environment
Underinf lated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not ha ndle
well a nd is more difficult to stop. Over load ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
ve hicle and can lead to sudden tire failure , in­
cluding a blowout and sudden deflation that
can cause the veh icle 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
a nd everyth ing in and on the vehicle . T hese
load limits are tech nica lly refe rred to as the
ve hicle 's
Gross V ehicle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory insta lled accesso ries, a full
tank of fuel, oi l, coo la nt and othe r fluids pl us
maximum load. The maxim um load includes
the number of passengers that t he vehi cle is
intended to carry ("seating capacity") w ith an
assumed weight o f 150 lbs (6 8 kg) for each
passenger at a designated seating pos ition
and the tota l weight of any l uggage in th e
ve­
hicle. If you tow a trailer, the weight of the
trailer hitch and the tongue weig ht of the loaded tra
ile r must be included as part of the
vehicle load .
T he
Gro ss Axle Weight Rating (" GAWR") is
the max imum load th at can be applied at e ach
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weight Ra ting are listed on the
sa fety comp liance s ticke r label lo cated on the
driver's side B-pillar. Your Audi has 5 seat ing
positions, 2 in the front and 3 in the rear fo r
total seat ing capac ity of 5. Each seating posi ­
t ion has a seat be lt
c:> page 149, Safety bel ts.
The fact that there is an upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
tra iler hitch and the tongue weight of the
loaded tra iler) is lim ited . The more passen ­
gers in the vehicle or passenge rs w ho are
heavier than th e standard we ights assumed
mea n tha t less we ight can be carried as lug­
gage .

the max imum combi ned weig ht of a ll of the
occupants and luggage or other cargo that
the vehi cle can carry . For t he lo ca tion of the

A WARNING
Overloading a vehicle can cause loss of ve ­
hi cle cont ro l, a c rash or other accident, se­
rious personal injury, and even death.
- Ca rrying more we ight than your veh icle
was des igned to carry wi ll prevent the
veh icle from handling pr operly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail s uddenly, including a blowout
a nd sudden defla tion, causing loss of
contro l and a c rash .

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal 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 t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es 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 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 failure
and loss of vehicle control. Tires and wheels 259

26 2 T ire s and wheel s
-All four wheels must be fitted with radia l
t ires of the same type, size (roll ing c ir­
cumference) and the same tread pattern.
Driv ing with different tires reduces veh i­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
t ir es that are mounted on the veh icle -
for example with wi nter tires - on ly use
the spare tire for a short period of time
and dr ive with extra care. Refit the no r­
ma l road whee l as soon as safely possi ­
ble.
- Never drive faster than the maxim um
speed for which the tires on your vehicle
are rated because tires that are drive n
faster than their rated speed can fail
sudden ly.
- Overloading ti res cause heat build- up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are properly inflated and not over or un­
derinflated.
- For technical reasons it is not a lways
poss ible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel tr im discs on the ve­
hicle whee ls, make sure that the air flow
to the brakes is not blocked . Reduced air­
flow to the brakes can them to overheat,
increasing stopping d istances and caus­
ing a collision.
- Run flat t ires may on ly be used on
vehicles that we re eq uipped w it h them
at the f acto ry. The vehicle must have a
chassis des igned for r un flat t ires . Incor­
rect use of run flat tires can lead to vehi­
cle damage or acc idents . Check with an
authorized Audi dealer or t ire specia list
to see if your vehicle can be equipped
with run flat t ires. If run flat tires are
used, they must be installed o n all four
wheels. Mix ing tire types is not permit­
ted. (D Note
- For technical reasons, it is not generally
poss ible to use the wheel rims from oth­
er veh icles. T his can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is diffe rent from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire w it h the
ti re mat ching the othe rs on your vehicle
as soon as possi ble.
- Never d rive without the valve stem cap.
T he v alves co uld get damaged.
@ For the sake of the environment
Dispose of o ld tires in accordance w ith the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Tra ction AA A B (
- Temperature ABC
Quality grades can be found where applicab le
on the tire s ide wall between tread shoulder
and maximum section width
¢ page 259,
fig . 207 .
For example: Tread wear 200 , Traction AA ,
Temperature A .
All passenger car ti res must conform to Feder­
al Safety Requirements in add ition to these
grades .
Tread wear
The tread wear g rade is a comparative rating
based on the wear rate of the tire when tested
u nder contro lled conditions o n a specified
government test course.
F o r example, a tire graded
150 wo uld wear
one and one ha lf
(11/2) times as well on the

driving a few yards and correct if neces­
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(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<=>
page 297.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop­
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
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
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 265
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
105 ft lb (140 Nm) with a to lerance of
± 7,4 ft lb(± 10 Nm). Torque wheel bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i­
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k­
shop.
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 . ..,.

@ Tips
- Do not operate the compressor for more
than 12 minutes continuously, otherwise i t can overheat. Once the compressor has
cooled, you can continue to use it.
- If sealant has spi lled out, let it dry and
then you can remove it by pee ling it away
like a fo il.
- Remember to obtain a new bottle of
sealant from your authorized Audi dealer
after repairing a tire. After this, the func­
tionality of the tire repair set is restored.
- Obey all laws.
Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel .
.,. After you experience a tire fa ilure, pull the
car well away from moving traffic and try to
reach
le ve l ground before yo u stop ¢&_ .
.,. All p assengers sho uld
le ave the c ar and
move to a safe location (for instance, behind
the guardrai l)¢

A WARNING
You or your passengers cou ld be injured
while changing a whee l if yo u do not fol­
low these safety precautions:
-
- If you have a flat tire, move a safe d is­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to a lert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly a nd possib ly slipping off the
jack*, always fully set the pa rking brake
a nd b lock the wheel d iagonally opposite
t he wheel be ing c hanged w it h t he fold­
ing chocks or other objec ts. When one
front wheel is lifted off the ground, plac ­
ing the Automatic Transmission in P
(Park) will
not prevent the vehicle from
