2013 AUDI Q5 brakes

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 .
T he t ire pressure label on your Aud i also lis ts
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
label <=>page 252, fig. 203.
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 .
~

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
government course as a ti re graded
100.
