2014 AUDI A7 weight

Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge ¢ page 11
must be observed carefully. The coo lant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the display turn on .
For more information about indicator lights,
refer to.

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wearing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
-
a trailer because of the additional weight and
d ifferent weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig .
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic . Keep practicing until you
have become completely familiar with the way
your veh icle-trailer comb ination behaves and
responds .
Backing up is diff icult and requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
Trailer towing 211
trailer, you wi ll need a larger than normal
turning radius.
When passing, remember that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow
plenty of room for your trailer before chang­
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(0 Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load¢
page 285.
Parking on a slope
Do not pork on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
"' App ly the foot brake .
.,. Have someone place chocks under both the
veh icle and the trailer wheels.
"' With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.,. Turn the wheels towards the curb.
.,. Apply the parking brake.
.,. Select the P selector lever posit ion.
When restarting after parking:
.,. App ly the foot brake.
.,. Start the engine.
.,. Select the D/S selector lever position .
.,. Release the parking brake and slowly pull
out and away from the wheel chocks.
.,. Stop and have someone retr ieve the wheel
chocks .

General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tively small patch of rubber on each tire that
assures that a ll- important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han­
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage i nclud­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
A voidin g damage
If you have to d rive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re­
i nstall them .
When removed, the wheels or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .
Tires an d wheel s 243
New tires
New ti res have to be broken in¢& .
The tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
patte rn.
H idden damage
Damage to tires and r ims is ofte n not readily
visible . If you notice unusual v ib rat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au­
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar­
rows on the sidewa ll, that po int in the direc­
tion the t ire is designed to rotate. You mus t
f ol low the specified di rection o f rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information
¢ page 271.
A WARNING
New tires or t ires that are o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in. To reduce the r isk of losing
control, a co llision and ser ious personal
in ju ries, d rive with special ca re for the
fi rst 350 m iles ( 560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowout and sudden de­
fl ation, cras hes and se riou s personal in­
juries . Have worn or damaged t ires re­
placed immediate ly.
- Ti res age even if they are not being used
and can fai l sudden ly, especially at hig h
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.
•
•

24 4 T ire s and wheel s
-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.

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 2 00 Tire pressu re lab el: located o n drive r's side B­
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-

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

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

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

- 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 ­

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
t h e time it was ma nufactu red. For the lo ca­

-The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified tire pressure values
for the tires and the correct pressu res for
the funct ion of the tire pressure mon itor­
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated tires bend
more, letting them get too hot resu lting
in tread separation, sudden t ire fa il u re
and loss o f control.
- Excessive speed and/ove rloading can
cause heat bui ld-up, sudden tire fail ure
and loss o f control.
- If the t ire pressure is too low or too high,
the tires w ill wear prematurely and the
vehicle will not hand le we ll.
- If the t ire is no t flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta­
tio n to check the tire pressure and add
air as required.
(D Note
Dr iving without va lve stem caps ca n cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secure ly
mounted on the va lve.
@ For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption .
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 w ill not handle
well and is more difficult to stop . Overload ing
can not on ly lead to loss of vehicle con trol,
b ut can a lso damage important par ts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Tire s an d wheel s 251
Your safety and that of your passengers also
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
Gro ss Ve hicle Wei ght R ating
("GVWR") .
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
in tended to carry ("seat ing capac ity") with an
assumed we ight of 150 lbs (68 kg) for each
passenger at a designated seating posit ion
and the total weight of any luggage in the ve­ hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
Gr oss Ax le We ight R ating ("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 comp liance sticker label located on the
driver's side B-pillar. Your Audi has 4 seat ing
pos itions, 2 in the front and 2 in the rear for
total seating capacity of 4 . In some vehicles
there are 5 seating pos it ions, 2 in the front
and 3 in the rear for tota l seating capacity of
5. Each seat ing position has a safety belt
~ page 140, Safety belts .
The fact that there is a n upper limit to you r
vehicle's Gross Vehicle Weight Rating means
that the total weig ht of whatever is being car­
ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded trai ler) is limited . The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage .
The tire pressure label on your Audi also lists
the maximum combined weight of a ll of the
occupants and luggage or other cargo that ..,.
