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 important parts of the
vehicle and can lead to sudden tire failure in-
,
eluding a blowout and sudden deflation that
can cause the vehicle 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
Gross Vehicle Weight 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
hicle. If you tow a trailer, the weight of the
trailer hitch and the tongue weight of the
loaded trailer must be included as part of the
veh icle load .
The
Gross Axle Weight Rating ("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 -pillar. Your Audi has 5 seating
positions, 2 in the front and 3 in 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 175,
Safety belts .
The fact that there is an upper limit to your
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 trailer) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less weight can be carr ied as lug­
gage .
The tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the vehicle can carry . For the location of the
label
q page 284, fig. 251.
_& WARNING
Overloading a vehicle can cause loss of ve­
h icl e 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 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 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 we ight 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

other things that you plan to
transport 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 284,
fig. 251.
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 pas­sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 284, fig. 251 .
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-
Tires and wheels 289
pa city is 650 lbs. (1400-7 so
(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
( ¢ page 291 , fig. 255) to de­
termine the designated load rating for a specific tire.

304 What do I do now?
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 failure, pull the
car well away from moving traffic and try to
reach
level ground before you stop ¢,& .
• All passengers should
leave the car and
move to a safe location (for instance, behind
the guardrail) ¢
A-
.. Engage the parking brake to prevent your
vehicle from rolling unintentionally ¢,& .
• Move
selector lever to position P <=> ,&.
• If you are towing a trailer: unhitch the trail­
er from your vehicle.
• Block the diagonally opposite wheel wi th
the folding chocks or other objects.
• Take the
jack and the inflatable spare tire
out of the luggage compartment
¢page 301.
11. WARNING
=
You or your passengers could be injured
while changing a whee l if you do not fol­
low these safety precautions :
- If you have a f lat tire,
move a safe dis­
tance off the road . Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists .
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traff ic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed with the fold­
ing chocks or other objects. When one
front whee l is lifted off the ground, plac­
ing the Auto mat ic Transmission in "P"
(Park) will
not prevent the vehicle from
moving .
-
-Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed befo re you are able to get to the
bulb. This applies especially to the light bulbs
in the front of your car which yo u can only
reach through the engine compartment.
Sheet metal and bu lb holders can have sharp
edges that can cause se rious cuts, and pa rts
must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly re sea led.

..&, WARNING
- The Gross Vehicle Weight Rat ing for yo ur
vehicle, found on the sa fe ty compliance
label on the driver's side B -pillar , must
never be exceeded under any circumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of your vehicle is likely to damage
your vehicle, and such damage will not be covered by your Lim ited New Vehicle
Warranty . Exceeding the Gross Vehicle
We ight Rating will also change the per­
formance and handli ng characterist ics of
yo ur vehicle , which cou ld cause a crash
result ing in serious in jury or death.
- The Gross Vehicle Weight Rat ing for your
vehicle would be exceeded if yo ur vehicle
is simultaneous ly equipped with Pano r­
amic sliding sunroof; third-row seating;
trailer towing equipment (factory or
dealer-installed), and running boards
(dealer-installed) . UNDER NO CIRCUM­
STANCES MAY ALL SUCH ITEMS BE IN­
STALLED ON T HE SAME VEHICLE .
- The actual Gross Axle Weight Rat ing at
the front and rear axles shou ld not ex ­
ceed the perm iss ible weights, and their
combination must not exceed the G ross
Vehicle Weight Rat ing .
Gene ral in formation 32 1
-Exceeding perm iss ible weight ratings can
result in veh icle damage, acc idents and
personal injury.
([) Note
-The ve hicle capacity weight figu res apply
when the load is d istr ibuted evenly in the
vehicle (passengers and luggage). When
transport ing a heavy load in the luggage
compartment, carry the load as near to
the rear axle as poss ible so that the vehi­
cle's handling is not impaired .
- Do not exceed the maximum permissible
axle loads or the maximum gross veh icle
we ight. Always remember that the vehi­
cle's handling w ill be affected by the ex­
tra load. Therefore, ad just yo ur speed ac­
co rding ly.
- Always observe local regulat ions .

T he specifications refer to the basic model.
D ifferences may occur depending on the mod­
el type and op tions ordered , fo r example , tire
sizes .
Q) Note
When dr iv ing up steep ramps, on rough
r oads, over c urbs, etc. it is important to re ­
member that some parts of your vehicle,
such as spoi lers or exhaust system compo­
nents, may be close to the ground. Be
careful not to damage them .
