Remember, your safety and t hat o f your passengers also depends o n
making sure th at load limit s are not exc ee ded . V ehicle load in cludes
every body and everything in a nd on the veh icl e. These load limits are
tec hnically refer red to as t he ve hicle's G ross Vehicle Weight Rating
("G VWR") . The Gross Axle Weight Rat ing ("GA WR") is th e max imum
load that can be a pplied at each of the ve hicle's two ax les. The Gross
Vehicle Weigh t Rating and the G ross Ax le W eig ht R ating are listed on
the safety comp liance st ic ker label located either on the driver's side
B -pillar or on t he inside of th e f uel fi ller f lap. T he tire press ure label
on yo ur Audi lists the maximum comb ined weig ht of all of the occu­

& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident, serious personal injury, and even death .
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the risk of a loss of vehicle control.
• 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 overloaded can fail suddenly
causing loss of control and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating.
& WARNING
• Incorrect tire pressure s and/or underinflation can lead to a
serious or fatal accident .
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle .
Safety first
& WARNING (cont inued )
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The cor rect t ire pres sure fo r the tires o rig inall y installed
on you r veh icle is list ed o n the t ire pr ess ure la bel l ocat ed
e ither on driver's s ide 8-pillar or insi de th e fue l fill er flop.
Th e recommended tire pressure s are on the tire pressur e l abe l and in
the table ~
page 295, "Cold tire inflation press ure" .This means that
t he pressure must be check ed an d a dju sted w hen the tire h as no t
been dr iven for more tha n a cou ple of m iles (k ilometers) at low
s peeds dur ing t he pr evious t hree hour s. Air in the tires ex pands w hen
t he tire heats up as a resu lt of i nterna l fric tion as it flexes in use. The
tire pressu re is hig he r when the t ire has warmed up than when it is
"cold ."
It is the in flation press ure in a "cold" t ire that counts. Therefore, yo u
sh oul d n eve r le t a ir ou t of a warm t ir e to ma tch "C old tire in flatio n
pressure" recommendations~
page 295. The t ires would then be
unde rin flat ed and co uld fail su ddenly.
Th e tire pressu re labe l on yo ur Audi lists t he recommended co ld t ire
inflation pressures at ma ximum capacity fo r th e new, o rigina l equip ­
me nt t ires that were on yo ur vehicl e at th e time it wa s manuf actured .

M ost t ires lose air natura lly ove r time. T hey c an also lose some air if
you d rive over a potho le or hit a curb while pa rking . It is usually not
poss ible to see whether the radia l ti res used today are unde rinflate d
just by loo king at them .
T he refore, be sure to check t ire pressures at least once a month and
alw ay s before go ing on a lo ng trip. Make sure to take the num ber of
people and the amount of luggage into account whe n ad justing tire .,.

in. WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be

• Tires on a vehicle that has been overloaded can fail suddenly,

• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating. •
Determining correct load limit
Use the example below to calculate 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 OCCUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehicle's placard (tire infla­
tion pressure label)==>
page 295J
fig. 212.
2. Determine the combined weight of the driver and passengers 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 295J fig. 212.
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400- 7 SQ (5
X 150) = 650 lbs.) ~

& WARNING (conti nu ed )
• If you install wheel trim disc s on the vehicle wheels , make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to ove rhe at, increasing stopping distances
and cau sing a collision .
0 Note
• For tech nical reasons, it is not ge ne rally poss ib le to use the wheel
r ims from other vehicles. This can hold true for whee ls of the same
veh icle type.
• If the spare tire is different from the t ires that you have mounted
on yo ur veh icle (for examp le w inte r tir es or wide profile tires), then
use the spare tire for a short per iod of t ime on ly and drive with extra
c are . Replace the fla t ti re wi th t he tire matc hing the o thers on you r
vehicle as soon as possible .
• If you should put differen t wheel s and tires o n yo ur vehicle (e.g.
w inter whee ls and t ires), you must be certa in that the wheels and
ti res are comp atib le with the t ire pressure mon ito ring system*.
Otherwise the system will register a malfu nction and a fau lt message
w ill be displ ayed. Fo r more informa tion, conta ct your au thori zed Au di
dealer.
• N ever drive wi tho ut the valve s tem cap. The valves co uld get
damaged .
Dispose of old t ires in accordance with the loca l requirements. •
Uniform tire quality grading
• Tread wear
• Tr act io n AA A B C
• T emperature A B C Quality grades can be fo
und where app licab le on the tire s ide wall
betwee n tre ad sho uld er and m aximum se ct io n width =>
page 3 03,
fig .216.
Fo r example : Tread wea r 200, Tract ion AA , Temperat ure A.
All passenge r car ti res mus t confo rm to Fe d er al Safety Requireme nts
in addition to these grades.
Tread wear
T he tread wear grade is a comparative rating based on the wear rate
of the t ire whe n tes ted under cont rolle d conditions on a specifie d
government test co urse.
F or example, a tire graded 150 would wear one a nd one hal f (1 1/2)
t imes as well on t he government course as a tire graded 100 .
The relat ive performance o f tires depen ds upon the act ua l conditions
of their use, however, and may de pa rt sign ifican tly from the no rm
due to variat ions in dr iv ing hab its, se rvice practices and differences in
ro ad characte ris tic s and climat e.
Traction
Th e traction grades, from high est to lowest, ar e AA, A, Band C. Those
grades represent the tire's ability to stop on wet pavement as
me asu red under con trolled conditions on spe cifie d gove rnme nt te st
surfaces of asphalt and conc rete . A tire marked C may have poo r trac­
ti on perfo rm an ce =>& .
Temperature
The temperature grades a re A (the h ig hest), B, and C, represen ting
the t ire's resistance to the generation of heat and its ab ility to d issi ­
p ate he at when teste d und er co ntro lled condition s on a s pecifie d
indoor laboratory test wheel.
Susta ined high tempera ture can cause the materi al of the tire to
degenerate and red uce tire life, and excessive te mperature ca n lead
to sudden tire failure=> & .
Th e g ra d e C c orresponds to a level of pe rforman ce which all
passenge r ca r tires must meet under the Federal Motor Veh icle
