Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
a trailer because of the additional weight and
different weight distribution. Safety, perform­
ance and economy wi ll 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 vehicle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trai ler genera lly requires
steering 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, you will need a larger than normal
turn ing radius .
When passing, remember that you cannot ac­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your tra iler before chang­
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes .
(D Tips
-Do not tow a tra iler 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
q page 293.
Parking on a slope
Do not park 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
vehicle 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.
.. App ly the parking brake.
.. Place an automatic transmission* in
P, re­
spectively a manual transmission in first or reverse gear.
When restarting after parking:
.. App ly the foot brake.
.. Start the engine.
.. Move the se lector lever to
D , respectively a
manual transmission in first gear .
.. Release the parking brake and slow ly pu ll
out and away from the wheel chocks.
.. Stop and have someone retr ieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto­
matic transmission* to
P before applying
the parking brake and before blocking the
whee ls, you may have to use more force
lat er to move the lever out of the
P posi­
tion.

vehicle from handling properly and in­
crease 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 overload­ ed can fail suddenly causing loss of con­
tro l and a crash.
- Always make sure that the tota l load be­
ing transported -including the weight of
a tra iler hitch and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cle Weight Rating.
_& WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious o r 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 fai l­
ure, including a blowo ut 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 either on driver's side 8-pillar or inside the fuel filler flap.
The recommended tire pressures are on the
tire pressure labe l and in the tab le
¢ page 256, 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 .
A ir in the tires expands when the tire heats up
as a result of inte rna l fr iction as it flexes in
use. The ti re p ress ure is higher when the tire
has warmed up than when it is "cold."
It is the inflat ion pressure in a "cold" tire that
counts. Therefo re, you should never let air out of a warm tire to match "Cold tire
inflation
pressure" recommendations ¢
page 256. The
t ires wo uld then be underinf lated and co uld
fail suddenly.
The tire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
maximum capacity for the new, orig inal
equipment tires that were on your vehicle at
the time it was manufactured. For the loca­
t ion of the labe l
¢page 256, fig . 210 .
Most tires lose air natura lly over t ime. They
can a lso lose some air if you drive over a pot­
hole or hit a curb while park ing. It is usually
not possible to see whether the rad ial tires
used today are underinflated just by look ing
at them.
Therefore, be sure to check t ire pressures at
least once a month and a lways before going
on a long trip . Make sure to take the number
of peop le and the amount of luggage into ac­
count when adjust ing ti re pressu re for a trip -
even one that yo u wou ld not consider to be
" long." See
¢ page 260, Tires and vehicle
load limits
for mo re important information.
Always use an accurate tire p ressu re ga uge
when checking and ad justing inflat ion pres­
sures . Check a ll of the tires and be s ure not to
forget the spare tire. If the pressure in any tire
is too high when the tire is "cold," let air o ut
of the tire s low ly 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 k ind of
dr iv ing you plan to do .
If the pressure in any tire is too low, note the
difference between the pressure in the co ld
t ire 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 vehi cle as listed on the on
yo ur vehicle and in th is m anu al and the kind
of d riving you plan to do.
Ne ver e xceed th e maximum infl ation pre s­
sure lis ted o n the tir e side wall for any rea ­
s on.

reduced speed to the nearest service sta­
t ion to c heck t he tire pressure a nd add
air as required.
Driving without va lve stem caps can 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 valve .
@I For the sake of the environment
Underinflated tires will also increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is ove rloaded w ill not ha ndle
well and is more difficult to stop. Over load ing
can no t on ly lead to loss of vehi cle contro l,
but can also damage important pa rts of the
ve hicle and can lead to sudden tire failure, in­
cluding a blowout and sudd en deflation that
can cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making s ure that load limits are
not exceeded . Vehicle load includes everybody
and everyth ing in and on the vehicle . These
load limits are techn ically referred to as the
ve hicle's
Gross Veh icle W eight Rat ing
(" GVWR ").
T he "GVWR" incl udes the we ight of the basic
vehicle, all f actory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus maximum load . T he maximum load includes
the number of passengers that the vehicle is in tended to carry ("seating capacity") with a n
assumed weig ht of 150 lbs . (68 kg) for e ach
passenger at a des igna ted seat ing pos ition
and the tota l we ight of any l uggage in the ve ­
h icle. If you tow a trailer, the weight of the
tra iler hitch and the tong ue weight of the
loaded trailer must be included as part of the
ve hicle load . T
he
Gro ss Axle We ight Rating ("GAWR") is
the maximum load that can be applied at each
of the veh icle's two axles .
T he Gross Vehicle Weigh t Rat ing and the
G ross Ax le Weight Rating are listed on the
safety comp liance sticker label located either
on the dr iver's s ide B-pillar or on the ins ide of
the fuel fi ller flap . Audi has
4 seating pos i­
t ions, 2 in the front and 2 in the rear for to tal
seat ing capac ity of 4 . Each seating position
has a seat belt ¢
page 154, Safety belts.
The fact that there is an upper limit to yo ur
vehicle 's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­ ried in the vehicle ( includ ing t he weight of a
t railer hitch and the tongue weight of the
l oaded tra ile r) is lim ited. The more passen­
gers in the vehicle or passengers w ho are
heavier tha n t he standard we ights assumed
mean that less weight can be carried as lug ­
gage.
T he tire pressure label o n your Aud i also lis ts
the max imum combi ned weight of a ll of the
occupants and luggage or other cargo that
t h e vehicle can carry. Fo r the location of the
label ¢
page 256 , fig. 210.
A WARNING
-Overloading a vehicle can cause loss of ve-
h icle contro l, a crash or other accident, se­
rious pe rsonal injury, and even death .
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The b rakes on a vehicle that has been
overloaded may not be abl e to stop the
veh icle w it hi n a safe distance .
- Tires on a vehicle that has been overload­
ed can fail s udden ly, incl uding a blowo ut
a nd sud den defla tion, causing loss of
con trol an d a crash.
- Always make sure that the total load be­
i n g tr anspor ted - incl ud ing t he weight o f
a trailer hitch and the tongue we igh t of a
~

loaded traile r - does not make the
vehicle heavi er than the vehicle's G ross
Vehicle Weight Rat ing.
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 vehi­
cle's placard (tire inflation
pressure label)
¢ page 256 ,
fig. 210 .
2. Determine the combined
weight of the drive r and pa s­
sengers that will be riding in
your vehicle.
3 . Subtract the combined
weight of the driver and pas­
sengers from
" XXX " kilo­
grams or
"XXX " pounds
shown on the sticker
¢page 256 , fig. 210.
4. The resulting figure equals
the available amount of car-
Tires and wheels 261
go and luggage load capaci­
ty. For exampl e, if the
"XXX"
amount equal s 1400 lbs.
and there will be five 150
lb s. passengers in your vehi ­
c le, the amount of available
c argo and lugga ge load ca­
pacity is 650 lb s. (1400-7 50
(5
X 150) = 650 lbs .)
5. Dete rmine the combined
weight of luggage and cargo being loaded on the vehi cle .
That weight may not safely exceed the available cargo
and luggage load capa city
cal culated in Step
4.
6 . If your vehi cle will be towing
a trailer , load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­ duce s the available cargo
and luggage load capacity of
your vehicle .
~ Check the tire sidewall
(¢ page 263 , fig. 214) to de­
term ine the designated load
rating for a specif ic t ire.

274 What do I do no w?
Replace it as quickly as possible with a stand ­
ard whee l and tir e.
There are some restric tions on the use of the
compact spare t ire . T he compact spare t ire
has been designed specifically fo r you r type of
vehicle . It must not be swapp ed with a com­
pact spare t ire from another type of veh icle .
Snow cha in s
For technical reasons, the use of snow chains
on the compact spare tire is
not p ermitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare wheel w ith
tire instead of a rear t ire. Install the snow
cha ins on the rear t ire and use it to rep lace
the defective front tire .
A WARNING
-Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and w ith ex­
treme caution and careful driving.
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possib le w ith the
normal wheel and t ire .
- After mounting the compact spare tire,
the tire pressure must be checked as
soon as poss ible. The tire pressure of the
compact spare tire must be 4 .2 bar; oth­
erwise, you risk hav ing an accident.
- Do not drive faster than SO mph (80 km/
h) . You risk having an acc ident .
-Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . You risk hav­
ing an acc ident.
- Never drive us ing more than one spare
wheel and tire . You risk having an acci­
dent .
- Normal summer or winte r tires must not
be mounted on the compact spare whee l
rim.
- For technical reasons, the use of tire
chains on the spare tire is not permitted.
If it is necessary to dr ive with tire chains, the spare wheel must be mounted on the
front ax le in the event of a flat in a rear
tire. The new ly available front wheel
must then be installed in place of the
rea r whee l w ith the flat tire . Installing
the t ire cha in before mounting the whee l
and tire is recomme nded .
- Loose items in the passenger compa rt­
ment can cause se rious personal injury
du ring hard bra king or in a n accident.
- Never store the inflatable spare ti re or
jack and too ls in the passenger com ­
partment.
- Always store all jacking equipment,
tools, and the inflatable spare t ire in
the luggage compartment.
-Tighten the knurled retaining screw for the inflatable spare tire securely .
Changing a wheel
· Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel.
" After you experience a t ire failure, pull the
car well away from mov ing traffic and try to
reach
l evel ground before you stop ¢ A_.
" All passengers should leave th e car and
move to a safe location ( for ins tance, behind
t he guardrail) ¢&_ .
" Engage the
pa rking brake to prevent your
vehicle from rolling unintentionally¢&_ .
" Shift into
1st gear on veh icles with manual
transmiss ion, or move the
selector leve r to
the P posit ion
