2014 AUDI A7 inflation pressure

A WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always keep the rear lid closed while driving .
- Never transport objects larger than
those fitting completely into the luggage
area because the rear lid cannot be fully
closed.
- If you absolutely must drive with the rear
lid open, observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­ dows, the power roof* and the rear lid are
securely closed and locked to reduce the
risk of injury when the vehicle is not being
used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
Gj) Tips
-Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel. Be sure
to keep these slots free and open .

Driving Safely 137
-The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. The tire pressure la­
bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­
mended cold tire inflation pressures for
the vehicle at its maximum capacity
weight and the tires that were on your
vehicle at the time it was manufactured.
For recommended tire pressures for nor­
mal load conditions, please see chapter
~page 247.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly~
page 136, Loading the luggage com­
partment.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.
For example , in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a
10-lb (4.5 kg) object are about 20 times the
normal weight of the item. This means that
the weight of the item would suddenly be about 200 lbs. (90 kg) . You can imagine the
injuries that a 200 lbs . (90 kg) item flying
freely through the passenger compartment
could cause in a collision like this.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
-Always use suitable mounting straps and properly secure items to the tie-downs in
.

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.

p ill ar
Tire pressure generally refers to the amo unt
of air in a t ire that it needs it to do its job and
safely car ry the combined load of the entire
vehicle and its contents . T ire pressure is
measured in kilopascals (kPa) , the interna ­
tional measu ring unit and in pounds per
s quare inch (PSI). Tire p ressure is based in
part on the vehicle's design and load limit -
the greatest amount of weight that the vehi ­
cle can carry safely and the t ire size . The prop­
er tire pressure is frequent ly referred to as the
" recommended cold tire inf lation pressure ."
Air in the tires expands when the ti re heats up
beca use of internal fri ct ion when it flexes in
use. The tire p ressure is higher when the tire
has warmed up than when it is "cold ." It is the
inflat ion p ressure in a "cold" ti re that counts.
Therefore, you should never let air out of a
warm tire to match "cold tire inflation p res­
sure" recommendations. The t ires would then
be underinflated and could fail suddenly .
Maintaining proper tire pre ssure is one of the
most important things you can do to help
avoid sudde n tire failure . Underinflated t ires
are a majo r cause of sudden tire failure . Keep­
i ng tires at the r ight pressure is also impor-

then e speciall y when hea vily loaded even
withi n the pe rmissible load -carrying capaci­

The recommended t ire pressures for your Audi
depend on th e kind of tires on your vehicle
and the n umber of passengers and/or amount
of luggage you will be transporting.
The tire pressure label is located on the driv­
er 's side B-pillar. The tire pressure labe l lists
the recommended cold tire inflat ion pressures
for the vehicle at its maximum capacity
weight and tires that were on your veh icle at
the time it was manufactured .
If you wish to imp ro v e co mfort when operat­
ing the vehicle at normal lo ad (up to 2 /3*

This is especially important if the vehicle be­l ongs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
veh icle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on making sure that l oad limits are not exceeded . Vehicle load in­
cludes everybody and everything in and on the
vehicle. These load limits are technically refer­ red to as the vehicle's Gross Vehicle Weight
Rati ng ( "GVWR") . The Gross Axle Weight Rat­
i ng ("GAWR") is the maximum load that can
be applied at each of the veh icle 's two axles.
The G ross Vehicle We ight Rating and the
Gross Axle We ight Rating are listed on the
safety compliance sticker labe l located on the

Overloading a vehicle can cause loss of ve ­
hicle control, a crash or other accident, se­
rious personal inju ry, and even death.
- Carry ing more weight than yo ur vehicle
was designed to ca rry will p revent the
vehicle from hand ling p roperly and in­
crease the ris k of a loss of veh icle con­
t ro l.
- T he bra kes on a veh icle that h as been
overloaded may not be able to stop the
vehicle within a safe distance .
- T ires on a vehicle that has been overload­
ed can fail suddenly causing loss of con ­
tro l and a c rash.
- Always make sure that the tota l load be­
ing transported -includ ing the weight of
a tra iler hitc h and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­

Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­ lar.
The recommended tire pressures are on the
t ire p ress ure label and i n the table
¢ page 247, Cold tire inflation pressure.This
means th at the pressure m ust be chec ked and
adjusted when the t ire has not been dr iven for
more than a couple of miles (kilometers) at
l ow speeds d uring the previous th ree ho urs .
Air in the tires expands when the tire heats up
as a result of internal frict ion as it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "cold."
It is the inflation pressure in a "cold" tire that
counts. Therefore, you should never let a ir out
o f a warm tire to match "Cold t ire inflat io n
pressure" recommendat ions ¢
page 247 . The
ti res wou ld then be unde rinflated and co uld

The tire pressure label on your Audi lists the recommended co ld tire inflation pressures at
max imum capacity for the new, or ig inal
equipment tires that were on your ve hicle at

used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at least once a month and always before going
on a long tr ip. Make sure to take the number
of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See
c> page 251, Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres­
sures . Check all of the t ires and be sure not to
forget the spare tire . If the pressure in any tire
i s too high when the tire is "cold," let air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure unt il
you reach the pressu re that is correct for the
l oad (passengers and luggage) and kind of
driving you plan to do.
I f the p ress ure in any tire is too low, note the
d ifference between the pressure in the cold
tire and the pressure you need and add the a ir
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as listed on the on
you r veh icle and in this manual and the k ind
of dr iving you plan to do.
Ne ver e xceed the m aximum inflation pre s­
su re li sted on the ti re sidewall for an y rea ­
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire p ressure fo r the t ires on your vehicle .
It is important to check the tire pressu re when
the tires are cold.
- Read the requ ired t ire p ress ure from the tire
pressure label. The ti re pressu re labe l is lo ­
cated on the drive r's side 8-pi llar.
- T urn the valve stem cap counter- clockwise
to remove i t from the tire valve.
- Place the air pressu re gauge on the valve .
- The tire pressures should only be checked
and adjusted when the tires a re cold . The slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on the va lve.
When sh ould I check the tire pressure?
The correct tire pressure is especially impor­
tant at h igh speeds. The pressure should
the refore be checked at least once a mo nth
and always before starting a jo urney. Do not
f orget to c heck the ti re p ress ure fo r the spare
whee l
i=;,poge 265.
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are
ca rrying. After changing a whee l
or replaci ng
whee ls yo u have to adj ust the ti re press ures
on all whee ls. In addition, you m ust then
store the new tire pressures in the tire pres­
s u re monito ring system*

A WARNING ~
Incorrect tire pressures and/or underinfla-
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warn ing symbol
RI] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and can affect the handling of the vehicle and
stopping ability .
- Inco rrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, ca us ing loss of veh icle cont ro l.
- The drive r is responsible for the co rrect
tire pressures for all tires on the veh icle.
T he applicable pressure values are loca t­
ed on a sticke r on the dr iver's s ide 8-pil­
lar .
- On ly when all tires on the vehicle are fil­
led to the correct pressu re, the t ire pres ­
sure monitoring* system can work cor­ rectly.

A WARNING
Overloading a vehicle can cause loss of ve­
hicle 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
vehicle within a safe distance.
- Tires on a vehicle that has been overload ­
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 weight 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 oth­
er things that you plan to trans­
port 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 ve­
hicle's placard (tire inflation
pressure
label)¢
page 247,
fig. 200.
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 247, fig. 200.
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 pacity is 650 lbs. (1400-7 50
(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.
