Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can carry.
A vehicle that is overloaded wi ll not handle
well and is more difficult to stop. Overload ing
can not on ly lead to loss of vehicle control
,
but can a lso damage impo rtant parts of the
vehicle and can lead to sudden tire failure in-
,
eluding a blowout and sudden deflation that
can cause the veh icle to crash .
Your safety and that of your passengers 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 are tech nically referred to as the
vehicle 's
Gr oss Vehicl e W eig ht Rating
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory installed accessories , a full
tank of fuel , oi l, coo lant and other fluids plus
maximum load. The maxim um load includes
the number of passengers that the vehicle is intended to carry ("seating capacity") with an
assumed weight of 150 lbs (68 kg) for each
passenger at a designated seating position
and the tota l weight of any l uggage in the ve­
h icle. If you tow a trailer, the weight of the
trailer h itch and the tongue weight of the
loaded trailer must be included as part of the
ve hicle load .
The
G ro ss Ax le We ight Rat ing ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles .
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker label located on the
driver's side B -p illar . Your Audi has 5 seating
positions, 2 in the front and 3 i n the rear for
total seating capacity of 5. On vehicles w ith
six seats*, your veh icle has two front seats,
two seats in the second row seating and two
seats in the third row seating . On vehicles
with seven seats*, your vehicle has two front
seats, three seats in the second row seating
and two seats in the third row seating . Each seating position has a seat belt
q
page 170,
Safety belts .
The fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle (including the weight of a
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mea n that less we ight can be carr ied as lug­
gage .
The tire pressure label on your Audi also lists
the maximum combined weig ht of a ll of the
occupants and luggage or other cargo that
the vehicle can carry . Fo r the location of the
label qpage278, fig. 237.
_& WARNING
Overloading a vehicle can cause loss of ve­
h icle cont ro l, a crash or other accident, se­
rious personal injury, and even death.
- Ca rrying more we igh t than your veh icle
was des igned to carry wi ll prevent the
vehicle from handling properly 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 over load­
ed can fail s uddenly, 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 we ight of a
loaded trailer -does not ma ke the vehi­
cle heavi er than the vehicle's Gross Vehi­
cle Weight Rating.

What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
eas ily by impact with potho les, curbs, gu llies
or ridges on the road, particularly if the tire is
underinflated.
I n order to minimize the occu rrence o f impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your t ires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
tir es or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ir e as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and unde rinflation, wh ich could eventu­
ally cause tire failure. If yo u be lieve that a
tire may have been damaged, replace the
tire as soon as possible.
- T hese tires may wear more quickly than oth­
ers.
- Please also remember that, while these tir es
deliver responsive handling, they may ride
l ess comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes .
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling . They are not suitable
for cold, snowy or icy weather condit ions . If you drive
under those circumstances, you
shou ld equip your vehicle with all-season or
winter tires , which offer better traction under
those conditions. We suggest you use the rec­ ommended snow or all-season t ires specified
for your vehicle, or their equivalent .
Refer to~
page 289 for more detailed infor­
mation regarding winter tires.
Tire pressure
monitoring system
General notes ill
Each tire, including the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s iz e indicated on the vehicle placard or tire in­
flat ion press ure la bel, you should determine
the proper tire inflation pressure for those
ti res.)
As an added safety feature, your ve hicle has
been equipped with a tire pressure monitoring
system ( TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. According­
l y, when the low tire pressure te lltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure . Driving on a sign ificantly un ­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's hand ling and
stopping ability .
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the leve l to trigger illuminat ion of the
T PMS low tire pressure tellta le .
Your vehicle has also been equipped with a
T PMS ma lfunction indicator to indicate when
the system is not operating properly. The
