110 Driving Safely
&_ WARNING
Always make sure that the doors, all win­dows, the power roof* and the read 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.
(D Tips
- The tire pressure must correspond to the
load -see the tire pressure sticker on the
fuel filler door.
- The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. On USA vehicles, the
tire pressure label is located on the driv­
er's side B-pillar. On Canada vehicles, the
tire pressure label is located either on
the driver's side B-pillar or inside the fuel
filler flap. The tire pressure label lists
the recommended 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 manu­
factured. For recommended tire pres­
sures for normal load conditions, please
see chapter ¢
page 216.

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 109, 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.
&_ 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
the luggage compartment to help pre­
vent items from shifting or flying for­ ward as dangerous missiles.
- When the rear seat backrest is folded
down, always use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to help prevent items from flying for­
ward as dangerous missiles into the pas­
senger compartment .
- Never attach a child safety seat tether
strap to a tie-down.

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, us ing
tire-r im combinations not approved by Aud i,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­ sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
se nsors and sent to the electron ic control
u ni t. Some suspens ion changes c an, for exam­
p le, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in w hic h it would not dep loy if the
changes had not been made. Other k inds of
changes may reduce the force levels meas­
ured by the sensors and prevent the airbag
from deploying when it shou ld .
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
l atched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
e r rate of vehicl e deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular co llision, it is poss ible th at an a irbag
will not deploy at a seating position where the
safety be lt is bei ng used but will inflate at the
position whe re the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so t hat the sen­
sors can send the correct information about
safety belt use to the electron ic cont rol unit.
A WARNING
Cha nging the vehicle's s uspension inclu d­
ing use of u napproved t ire-rim comb ina­
ti ons can change Advan ced A irb ag pe r­
formance and incre ase the risk of ser io us
personal in jury in a crash.
- Never ins tall suspe nsion compone nts
t h at d o not h ave the same per forman ce
characteristics as the components origi ­
nally installed on you r vehicle .
- Never use t ire-r im combinat ions that
have not bee n approved by A udi.
A irba g sy stem 13 7
A WARNING
Items stored between the safety be lt
buckle and the center console can cause
the sensors in the b uckle to send the
wrong informa tion to the e lectronic con­
trol module a nd prevent t he A dvan ced Air­
bag System from wo rking properly.
- Always ma ke sure t ha t nothing can inter­

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fi g. 135 Side a irbag location in t he drive r's seat
The side airbags are located in the sides of the
front seat backrests~
fig. 135 and the rear
back rest* facing the doors . Th ey are id entified
by the wo rd "AIRBAG".
The side airbag sy stem basically consi st s of :
-the electron ic control modu le and external
side impact sensors
- the two side airbags located in the s ides of
the front backrests
- two rear side airbags (as an ordered
option)
- t he airbag warn ing light in the ins trument
cl uste r.
T he airbag system is mo nitored e lec tronically
t o m ake ce rtain tha t it is fu nction ing p ro perl y
at all times . Each time you turn on the ig ni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) . ..,.

174 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durability,
economy and performance.
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reasons, always follow the operating
and drivi ng in str uctions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted securely on the ve hicle's chassis at a
technically sound location. Use only a trailer
h itch with removable ba ll mount. Always
check with the tr ailer hitch manufac turer to
make sure tha t you are using t he cor rect
hitch.
Do not us e a bumper hitch .
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper syst em. No modifications should
be made to the vehi cle exhaust and brake sys ­
tems. From time to time, check th at a ll hitch
mo unt ing bo lts remain securely fastened.
When you are not towing a trailer, remove the
tra iler hitch ball mount. This prevents the
h itch from causing damage sho uld your ve hi­
cle be str uck from behind
¢ A .
Tire pressure
When tow ing a traile r, inflate the t ires of your
ve hicle to the co ld tire pressure listed under
"Full load"on the stick er on the rig ht doo r- jamb. Inflate trailer tires to trailer and tire
manufacturers' specifications.
Lights
T he headlight set tings sho uld be checked with
t h e trai le r attached before d riving o ff. Have
the headlights adjusted as necessary so tha t
yo u can see t he road ahead b ut not blind on­
coming traffic.
Check to make sure bo th ve hicle and tr ailer
lights are wo rk ing properly .
Engine cooling system
T owing a t railer makes the engine work hard­
er.
It i s impo rtant that the cooling system's
performance stands up to the additional
stra in. Make sure tha t the cooling sys tem has
enough fluid.
Trailer brakes
If your trailer is equipped with a brak ing sys­
tem, c heck to be sure t hat it conforms to all
regula tions.
The trailer hyd raulic brake system must not be
directly connected to the vehicle's hydraulic
brake system.
Safety ch ains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the cha ins to per­
mit turning co rne rs. When yo u in stall safety
c h ains, ma ke sure they will not drag on the
r oad when you a re driving.
The chains should cross under the t railer
tong ue to prevent it from dropping in case of
separation from the h itch.
Trailer lights
Trai ler lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct w ir in g, sw itches and re lays .
Mir rors
If you are unable to see the traffic behind you
us ing the regular outside mirrors, then you

must install extended mirrors. I t is important
that you
always have clear vision to the rear.
A WARNING -
After removing the tra ile r hitch, do not
store it in your vehicle. In case of s udden
braking , the hitch could fly forward and in­
jure you or your passengers .
Operating instructions

Driving instructions
Driving with a trailer always requires extra
care and consideration .
To obtain the best possible handli ng of vehicle
and trailer, please note the fo llow ing:
... Do not tow a loaded t railer w hen you r ca r it­
self is not loaded .
... Be especially caref ul when pass ing other ve­
hicles .
... Obse rve speed lim its .
... Do not dr ive at the maximum permissib le
speed.
... Always app ly brakes e arly .
... Mon itor the tempe rature g auge.
Weight distribution
Towing a loaded t railer w ith an em pty car re­
su lts in a highly unstab le distrib ution of
weig ht. If th is cannot be avoided d rive at very
l ow speed s on ly t o a void t he ri sk of losi ng
stee ring cont rol.
A "ba lanced " rig is easier to operate and con­
tr ol. Th is means t hat the tow vehicle should
b e lo ade d to t he e xten t possible and per miss i­
ble while keep ing t he tr ailer a s light as possi ­
ble under the c ircu mstances . Wheneve r poss i­
ble, transfe r some ca rgo to the lugga ge com­
partment of the tow vehicle w hile obse rv in g
tong ue load requ irements and vehicle load ing
consideratio ns.
Speed
The higher the speed, the mo re di fficu lt it be ­
comes for the driver to contro l the rig . Do not
drive at the maximum permissib le speed. Re ­
duce your speed even more under unfavo rable
load, weather or wind conditions - partic ularly
whe n going downhill .
Red uce veh icle speed
immediately if the trail­
er shows t he slig htest s ign of sway ing.
Do not
try to stop the swaying by accelerating .
Observe speed limits . In some a reas speeds
f or vehicles tow ing tra ile rs a re lower than for
r egular veh icles .

216 Tires and wheels
Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle .
Fig. 167 Tire press ure labe l: loca ted ei the r on dr iver 's
side 8-pillar or inside the fuel filler flap
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 kilopascals (kPa), the interna­
tional measuring unit and in pounds per
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 safely and the tire size. The prop­
er tire pressure is frequently 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 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 inflat ion pres­
sure" recommendations. The tires would then
be underinflated and could fail suddenly .
Maintaining proper tire pressure is one of the
most important things you can do to help
avoid sudden tire failure. Underinflated tires
are a major cause of sudden 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.

POUR Pl.US DE
REHSEKi.\'IEME NTS
The recommended tire pressures for your Audi
depend on the kind of tires on your veh icle
and the number of passengers and/or amount
of luggage you will be transporting .
On USA vehicles, the t ire pressure label is lo­
cated on driver's side B-pillar . On Canada vehi­
cles, the tire pressure label is located e ither
on the dr iver 's side B-pillar or inside the fuel
filler flap . The tire pressure label lists the rec­
ommended cold tire inflation pressures for
the vehicle at its maximum capacity we ight
and tires that were on your vehicle at the 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 mon itoring
system * can on ly monitor the tire pressures
yo u have stored. The system does not recog­
nize the load condition of your vehicle.
T he effectiveness of the tire pressure monitor­
