to reduce the risk of injury when the vehi­
cle is not be ing 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. Be ing trapped in a vehicle can
lead to serious persona l injury.
- Never let children play in or around the vehicle .
- Never let passe ngers r ide in the luggage
compartment . Ve hicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air c irculation helps to reduce window
fogging. Sta le air escapes to the outside
th rough vents in the trim pane l. Be su re
to keep these slots free and open.
- The t ire pressure must correspond to the
load. The t ire pressur e is shown o n the
tire p ress ure label. The tire pressure la­
bel is loc ated on the d river's s ide B-pi ll a r.
The t ire pressure label lists the recom­
mended cold ti re inflat ion pressu res for
the vehicle at its maximum capacity
weig ht and the tires that were on you r
vehicle at the time it was manufactured.
For recommended t ire pressures fo r nor­
mal load conditions, please see chap ter
c:>page 199.
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
c:> page 100, Loading the luggage com­
partment.
In a coll is ion, the laws of phys ics mean that
even smalle r items that are loose in the vehi­
cle will become heavy missiles that can cause
Dr iving S afel y 101
serious injury. Items in the ve hicle possess en ­
ergy which vary with vehicle speed and the
weight o f the item . Vehicle speed is the most
s ignificant factor.
Fo r example, in a fronta l collision at a speed
of 30 mph (48 km/h), the forces acting on a
10 -lb (5 kg) object a re about 20 times the
no rmal weight of the item. This means that
the weight of the item would sudden ly be
about 200 lbs. (90 kg) . You can imag ine the
i njur ies that a 200 lbs . (90 kg) item flying
fr eely th ro ugh the passenger compar tme nt
c ould cause in a co lli sion like this.
A WARNING
We ak, dam aged or improper str aps used
to secure items to tie -downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury .
-Always use s uita ble mount ing stra ps and
properly secu re items to the tie-downs in
the l uggage compa rtme nt to he lp pre­
vent items from shift ing or f ly ing fo r­
ward as dangerous missiles .
-When the rea r seat backrest is folded
down, a lways use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to hel p prevent items from fly ing for­
ward as dangerous missiles into the pas­
s enger compartment.
- Never attach a chi ld safety seat te th er

Fig. 139 Permit ted ball position of the trailer hitch
Trailer towing weights
With a factory-installed or an aftermarket
trailer hitch, the maximum permissible trailer
weight is 2,200 lbs (1,000 kg). The maximum permissible unbraked trailer weight is 1,650
lbs (750 kg) . These specifications apply when
driving on roads having an incline of less than
12%.
Permissible tongue load
For best vehicle handling under these
changed conditions, adjust the trailer load so
that the tongue load is at the maximum al­
lowable or slightly lower . You can get an ap­
proximation of the tongue load with a bath­
room scale or you can measure the load at a
trucking company or weighing station.
With a
factory-installed or an aftermarket
trailer hitch, the maximum permissible load
on the ball hitch may not exceed 220 lbs
(100 kg).
It is recommended to use the maxi­
mum permissible load.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢.&. in Driving instructions on page 168.
Ball mount
The trailer hitch may only be used with suita­
ble ball mount and ball¢
fig. 139. Installa­
tion of the hitch ball must be carried out in ac-
Trailer towing 167
cordance with the manufacturer's instruc­
tions.
Engine cooling system
Towing a trailer makes the engine work hard­
er .
It is important that the cooling system's
performance is up to the additional load.
Make sure that the cooling system has enough
fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the tire pressure label. The tire
pressure label is located on the driver's side B­
pillar. Inflate trailer tires to trailer and tire
manufacturers' specifications .
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check
to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety
chains, make sure they will not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following :
.,. Do not tow a loaded trailer when your car it­
self is not loaded.
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits.

196 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
yo u 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. 152 Tire press ure label: located on driver 's s ide B·
p ill ar
Tire pressure generally refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the interna­
tional measuring unit and in pounds pe r
square inch (PSI). Tire pressure is based in
part on the vehicle 's design and load limit -
the greatest amount of weight that the vehi­
cle can carry safe ly and the t ire size . The prop­
er tire pressure is frequent ly referred to as the
"recommended cold tire inflation pressure."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use . The tire pressu re is higher when the tire
has warmed up than when it is "cold ."
It is the
in flat ion pressure i n a "cold " tire that counts.
Therefo re, you shou ld neve r let air out of a
warm tire to ma tch "cold tire inflat ion pres­
sure" recommendations. The tires would then
be underinflated and could fail suddenly .
Maintaining proper tir e pressure is one of the
most impor tant things you can do to help
avoid sudden tire failure. Underinflated tires
are a ma jor cause of s udden tire failure . Keep·
ing tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

traction, braking and load carrying. Tire pres­
sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci­
ties approved for your vehicle.
The recommended tire pressures for your Audi
depend on the kind of tires on your ve hicle
and the number of passengers and/o r amount
of luggage you w ill be transporti ng.
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 io n pressures
for the vehicle at its maximum capacity
weight and tires that were on your veh icle at
t he time it was manufactured.
If you wish to improve comfort when operat­
ing the vehicle at normal load (up to 3 occu­
pants), you can adjust tire pressures to those
specified for normal vehicle load. Before op­
erating the vehicle at maximum load, you
must increase the tire pressures to those
specified for maximum vehicle load
¢ &.
Bear in mind that the tire pressure monitoring

Because technical changes may be made to
vehi cle equipment dur ing the model year, al­
ways compare the tire size designation on the
tire pressure labe l on your vehicle with the
tires on your vehicle . Make sure that the tire
size information on the veh icle label is the
same as the size of the t ires on the vehicle.
This is especially important if the vehicle be­
longs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
load limits are not exceeded . Vehicle load in- eludes
everybody and everything in and on the
vehicle. These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rat ing ("GVWR"). The Gross Axle We ight Rat­
ing ("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 sticker label located on the
dr ive r's side 8-pillar. The tire pressure labe l on
you r Audi lists the max imum combined
weight of all of the occupants and luggage or
other cargo that the ve hicle can carry. For the

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 a 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 causing loss of con­
trol 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.
A WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­
dent .
- Incorrect tire pressures and/or underin­ flation cause increased tire wear and can
affect the handling of the vehicle.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
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
tire pressure label and in the table
c::;, page 199, Cold tire inflation pressure . This
means that the pressure must be checked and
adjusted when the tire has not been driven for more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Tires and wheels 201
Air in the tires expands when the tire heats up
as a result of internal friction 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 air out
of a warm tire to match "Cold tire inflation
pressure" recommendations
c::;, page 199 . The
tires would then be underinflated and could
fail suddenly .
The tire pressure label on your Audi lists the recommended cold tire inflation pressures at
maximum capacity for the new, original
equipment tires that were on your vehicle at
the time it was manufactured . For the loca­
tion of the label
¢page 199, fig . 152 .
Most tires lose air naturally over time . They
can also lose some air if you drive over a pot ­
hole or hit a curb while parking.
It is usually
not possible to see whether the radial tires
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 trip. 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 203, 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 tires and be sure not to
forget the spare tire. If the pressure in any tire is 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 until
you reach the pressure that is correct for the load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on .,.. •

s on.
Remember that the vehicle manufacturer, not
the tire manufacturer , determ ines the co rrect
tire pressure for the t ires on your veh icle .
It is important to check the tire pressure when
the tires a re cold .
- Read the required t ire pres sure from the tire
pressure label. The ti re pressure label is lo­
cated on the driver's side 8-p illar . The t ire
pressure label lists the recommended cold
t ire inflat ion p ressu res for the veh icle at its
maximum capacity we ight and the tires that
were on you r vehicle at the time it was man­
ufactured . For recommended tire pressures
for normal load condit ions, please see chap­
ter
9 page 199.
-Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the a ir pressure gauge on the valve.
- T he tire pressures should on ly be checked
and adjusted when the tires are cold. The
s li ghtly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying .
- Reinsta ll the va lve stem cap on the valve.
When should I check the tire pressur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always befo re starting a journey. Do not
forget to check the tire pressure for the spare wheel.
When should I ad ju st th e tire p re ss ures?
Adj ust the tire p ressure to the load you are
carry ing . After chang ing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then in iti­
alize the new tire pressures in th e tire pres­
sure monito ring system*
c> page 213.
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
Rt] warning symbol 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 hand ling of the vehicle and
stopping abi lity.
- I nco rrect tire pressures and/or underin­
f lation can also lead to sudden t ire fail­
ure, including a blowout and sudden de­
flation, ca using loss of vehicle contro l.
- The driver is responsible for the co rrect
tire pressures for all tires on the veh icle.
The applicable pressure values are locat ­
ed on a sticker on the driver's side B -pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure monitoring system * can work cor­
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for

- Always inflate t ires to the recommended
and correct t ire p ressure before dr iving
off.
- Driving with underinf lated tires bend
mo re, letting them get too hot resulting
in tread sepa ration, s udden tire failure
and loss of cont ro l.
- E xcessive speed and/overloadi ng can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.
- I f the tire pressure is too low or too high,
the t ires will wear prema turely and the

air as required.
(D Note
Dr iving without va lve stem caps can cause
damage to the t ire va lves . To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secu re ly
mounted on the va lve .

Tires and vehicle load limits
There are limits to the amount of load or
weight t hat any veh icle and any t ire ca n car ry.
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 contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in ­
cluding a blowout and sudden deflation that
can cause the ve hicle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure th at load limits are
no t exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
load limits a re tech nica lly referred to as the
ve hicle's
Gross Veh icle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
ve hicle, all factory installed accessories, a full
tank of f uel, oil, coo lant and othe r fluids plus
max imum load. The maximum load includes
the number o f passenger s that the ve hicl e is
intended to carry ("se ating capacity") w it h an
assumed weig ht o f 150 lbs. (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve­
h icle. If you tow a trailer, the weight of the
trailer hitch and the tong ue weight of the
Tire s an d wheel s 203
loaded tra ile r must be included as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating (" GAWR") is
the max imum load th at can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are l iste d on the
s af ety comp liance s tic ke r la bel lo cated on the
driver's side 8 -pillar . Yo ur Audi has 5 seating
positions, 2 in the front and 3 in the rear fo r
total seating capacity of 5. Eac h seating posi ­
tion has a seat be lt

T he fac t that there is an upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car ­
ried in the vehicle ( includ ing the weight of a
trai ler hitch and the tongue weight of the
l oaded tra ile r) is lim ited . The more passen ­
gers in the vehicle or passe ngers w ho are
heavi er than the standard we ights assumed
mea n that less we ight can be ca rried as lug­
gage.

A WARNING
-=
Overloading a vehicle can cause loss of ve -
h icle cont ro l, a c rash or other accide nt, se ­
rious pe rsonal injury, and even death.
- Ca rrying more we ight than your vehicle
was des igned to carry wi ll prevent the
veh icle from handling pr oper ly 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
ve hicle w it hi n a safe distance.
- Tires o n a vehicle that has been over load­
ed can fail s uddenly, incl uding a blowout
a nd sudden defla tion, causing loss of
con trol an d a crash . ..,.
