and is more difficult to stop. Overloading can not only lead to loss
of vehic le contro l, but can also damage important parts of the
vehic le and can lead to sudden tire failure, including a blowout and
sudden deflation that can cause the vehicle to crash .
Your safety and that of your passengers also depends on making sure that load limits are not exceeded . Vehicle load includes every ­
body and everything in and on the veh icle . These load lim its are
technically referred to as the vehicle's
G ross Vehicle Weight R ating
("GVWR").
The "GVWR" includes the weight of the basic vehic le, all factory
installed accessories, a ful l tank of fuel, oil, coolant and other fluids
p lus maximum load. The maximum load includes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed we ight of 150 lbs (68 kg) for each passenger at a
designated seating position and the total weight of any luggage in
t he vehicle. If you tow a trai ler, the weight of the trailer hitch and the
tongue weight of the loaded trai ler must be included as part of the
vehic le load .
T he
G ros s Axle Weight Rating ("GAWR") is the maximum load that
can be applied at each of the vehicle's two axles .
The Gross Vehicle Weight Rat ing and the Gross Axle Weight Rating
are listed on the safety compliance sticker labe l located either on
the d river's side B -pillar o r on t he inside of the f ue l fi ller flap. Yo ur
Audi has 4 seating positions, 2 in the front and 2 in the rear for total
seating capaci ty of 4. Each seating posi tion has a safety belt
=>
page 159, "Safety be lts" .
T he fact that there is an upper limit to your vehicle's Gross Vehicle
Weight Rating means that the total weight of whatever is being carried in the vehicle (including the weight of a trailer hitch and the
tongue weigh t of the loaded trailer) is lim ite d. The more passengers
in the vehicle or passengers who are heavier than the standard
weights assumed mean that less weight can be carried as luggage.
The tire pressure labe l on your Audi also lists the maximum
combined weight of a ll of the occupants and luggage or othe r cargo that the vehicle can carry
. For the location of the label=>

i ncluding a blowout and sudden defla tion , cau sin g los s of control

toring system* would not be able to monitor the tire pressure or
warn you if it is necessa ry.
• T he battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
r ecommend us ing facto ry insta lled va lve stem caps. Ask you r autho ­
rized Audi dealer to replace lost va lve stem caps.
T he installation of rep lacement tires with steel cord body p lies in
t he tire sidewall may cause mal functi on of the tir e pressure mo ni­
toring system , and is not recommended (cord material information
in mo lded o n th e ti re sid ewa ll) .
Always check your tire pressure monitoring system * indicator after
r eplacing one or mo re ti res on your veh ic le . I f the ti re p ress ure
m onito ring syste m* ind icator flashes, or is o n, your s ystem is not
wo rking properly . Your replacement t ire might be incompatible with
yo ur tir e pressure mon ito ring system* , o r so me compo nen t of th e
tire p ressure monitoring system * may be damaged .
& WARNING
• Using incorrect or unmatched tires and I or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always use t ires , rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fa il suddenly,
espe cially 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 speed s.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tire s may have been damaged
even though the damage cannot be seen that can lead to sudden
tire f ailure and loss of vehicle control.
& W ARNING (continued )
• All four wheels mu st be fitted with radial tires of the same type,
size (rolling circumference ) and the same tread pattern. Driv ing
with different tires redu ces vehicle h andling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for e xample with winter tire s - only u se the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
the ir rated speed can fail suddenly .
• Overloading tires cause heat build-up, sudden tire failure ,
including a blowout and sudden deflation and loss of control .
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chnical reasons it is not always possible to use wheels
from other vehicle s -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked. Redu ced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision.
• Run flat tire s may only be used on vehicle s that were equipped
with them at the fa ctory . The vehicle must have a cha ssis designed
for run flat tires and a factory -installed tire pressure monitoring
s ystem that indicate s a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
autho rized Audi dealer or t ire specialist to see if your vehicle can
be equipped with run flat tires .
If run flat tires are used , they mu st
be installed on all four wheels . Mixing tire types is not permitted. .,
