Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic. Keep practicing until you have be ­
come completely fami liar with the way your ve hi­
cle-trailer combination behaves and responds.
Backing up is d iff icu lt and requires practice . Back ­
i ng up w ith a trailer generally req uires steering
action oppos ite to that when backing up yo ur ve­
hi cle without a trailer.
M aintain a g reater distance betwee n your vehicle
and the one in front of yo u. You w ill need more
room to stop. To compensate for the tra iler, you
will need a larger than norma l turning radius.
When passing, remember that yo u cannot acce l­
erate as fast as yo u normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trailer before changing lanes again.
Avoid jerky sta rts, sharp turns or rapid lane
changes.
@ Tips
- Do not tow a tra ile r during the break-in peri­
od of yo ur vehicle.
- If yo u tow a t railer, you r A udi may require
more frequent ma intenance due to the ex­
tra load
~ page 262.
Parking on a slope
Do not park on a slope with a trailer . If it cannot
be avoided, do so only after doing the following:
When parking:
.. Apply the foo t brake .
.. Have someone pla ce chocks under bo th t he ve ­
hicle and the trailer wheels .
.. With c hocks i n place, s lowly re lease the brakes
u nti l the whee l chocks absorb the load .
.. Turn the wheels towards the c urb .
.. Apply the parking brake .
.. Se lect the P selector lever pos ition.
When restarting after parking :
.. Apply the foot brake .
.. Start the eng ine.
.. Se lect the D/S selector lever posit ion.
Trailer mode
.. Release the pa rking brake and s lowly pull out
an d away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks.
(D Tips
If you move the selector leve r of the automat­
i c transm iss ion to P before app ly ing the park­
i ng brake and before blocking the wheels, you
may have to use mo re force later to move the
l ever out of the P posit ion.

Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Contro l (ESC) reinfor­
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti ­
cal s ituations such as the vehicle oversteering
and understeering or the wheels a re spinning.
The vehicle is stabilized by applying the brakes or
reducing engine torque. Once the ESC is activat­
ed, the indicator light
DJ blinks in the instru­
ment cluster.
The fol low ing systems a re integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
i ng. The vehicle can still be steered even during
hard braking . Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal ind icates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking d is­
tance . It increases braking power when the driver
presses the brake pedal quickly in emergency s it­
uations. You must press and hold the brake pedal
unti l the dangerous sit uation is ove r. In vehicles
with adaptive cruise control *, the brake assist
system is more sensit ive if the distance detected
to the vehicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up inclines.
Intelligent Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other drive wheel
or whee ls if the vehicle is equipped with all wheel
drive*). This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over ­
heating. The vehicle is still working correct ly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
Selective wheel torque control
Selective wheel torque control is used when dr iv­
i ng on curves. The front wheel on the inside of
the curve o r both wheels on the inside of the
curve are braked selectively as needed . This al­
lows more precise driving in curves .
Automatic post-collision braking system
The "Automat ic post -collision braking system"
can help to reduce the ris k of sliding and of other
collisions after an accident. If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electr i­
cal system are not funct ion ing .
A WARNING
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i­
cal laws. This is especially important on slip­
pery or wet roads .
If the systems begin act­
ing to stabilize your vehicle, you should im-
mediately a lter your speed to match the ..,.

-Please observe information on safe driving
~page 130.
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 be­
cause 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 pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
A WARNING
Always make sure that the doors, all windows,
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 espe ­
cially with the rear lid left open . A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­ hicle's seating positions.
(D Tips
- Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel. Be sure to keep these slots free and open.
Driving safety
-The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar. 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 man­ ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter ~
page 224.
' 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 properly
~page 136, Loading the luggage compartment.
In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury. Items in the vehicle possess energy 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 col­
lision like this.
A WARNING
-Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard
braking or in a collision and cause serious per­
sonal injury .
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from shifting or flying forward as dan­
gerous missiles.
- When the rear seat backrest is folded down,
always use suitable mounting straps and
properly secure items to the tie-downs in

Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig. 117 Unbelted occupants in a ve hicle heading for a wall
Fig . 118 The vehicle cras hes into th e wall
CD
~ ± The physical principles are simple. Both the vehi­
cle and the passengers possess energy which var­ ies with vehicle speed and body weight . Engi­
neers call this energy "kinetic energy."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor. If the
speed doubles from 15 to 30 mph (25 to 50 km/
h) , the energy increases 4 times!
Because the passengers of this vehicle are not us­
ing safety belts
q fig. 117, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall
qfig. 118 .
The same principles apply to people sitting in a
vehicle that is involved in a frontal collision. Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
Safety belts
(2,000 lbs, or 1,000 kg) or more . At greater
speeds, these forces are even higher .
People who do not use safety belts are also not
attached to their vehicle. In a frontal collision
they will also keep moving forward at the speed
their vehicle was travelling just before the crash.
Of course, the laws of physics don't just apply to
frontal collisions, they determ ine what happens
in all kinds of accidents and collisions.
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop themselves from flying forward and being in­
jured or killed . Always wear your safety belts!
Fig. 119 A dr iver not wea ring a safety belt is vio lently
thrown forward
Fig. 120 A rear passenger not wearing a sa fety belt w ill fly
fo rward and strike t he drive r
Unbelted occupants are not able to resist the tre ­
mendous forces of impact by holding tight or
bracing themselves . Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam v iolently into the steering wheel, in­
strument panel, windshie ld, or whatever else is
in the way
q fig . 119 . This impact with the vehi­
cle interior has all the energy they had just before
the crash. ..,_

Safety belts
Never rely on airbags a lone for protection . Even
when they deploy, airbags provide only additional
protection . A irbags are not supposed to deploy in
all kinds of accidents. Although your Audi is
equipped w ith airbags, all vehicle occupants, in­
cluding the driver, must wear safety belts cor ­
rectly in orde r to min imize the risk of seve re in­
jury o r death in a crash .
Remember too, that airbags will deploy only once
and that your safety be lts are a lways there to of ­
fer protection in t hose accidents in which airbags
are not supposed to deploy or when they have a l­
ready deployed . Unbelted o ccupan ts can also be
thrown ou t of the vehicle where even mo re severe
or fata l injur ies can occur .
It is also important fo r the rea r passenge rs to
wear safety belts co rrectly. Unbe lted passenge rs
i n t he rear se ats endanger not only themselves
but also the driver and other passengers
~ fig . 120. In a frontal coll ision they wi ll be
thrown forward violent ly, where they can hit and
in ju re the driver and/or front seat passenger.
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision . It 's simply
not true!
F ig . 121 Driver is correct ly restra ined i n a sudden b rak ing
m aneuver
Safety belts used properly can make a big differ­
ence. Safety belts help to keep passengers in
their seats , gradually reduce energy levels ap­
plied to the body in an accident, and he lp prevent
the uncont ro lled movement that can cause seri ­
ous injur ies. In add it ion, safety belts reduce the
danger of being throw n ou t of the vehicle.
142
Safety be lts attach passengers to the car and give
them the benefit of being s lowed down more
gently or "softly" through the "give" in the safety
belts, crush zones and other safety features eng i­
neered into today's veh icles. By "absorbing" the
ki net ic ene rgy over a longer period of time, the
safety be lts make the forces on the body more
"tole rable" and less li kely to cause injury .
Although these examples are based o n a frontal
collision, safety be lts can also substantially re ­
duce the r isk o f injury in other kinds o f crashes.
So, whether you're on a long tr ip or just go ing to
t he cor ne r store, always bu ckle up and ma ke sure
o thers do, too. Ac ciden t sta tis tics show that ve hi­
cle occupants properly wearing sa fe ty belts have
a lowe r risk of be ing injured and a much better
chance of surviving an accident. Pro perly using
safety belts a lso greatly increases the ab ility of
the supp lemental airbags to do their job in a col­
li sion. For this reason, wear ing a safety be lt is le­
gally required in most countries including much
of the United States and Canada .
Although your Audi is equipped with a irbags, you
still have to wear the safety belts provided. Front airbags, for example, are act ivated only in some
fron tal coll is io ns . The front airbags are not act i­
vated in a ll frontal col lisions, in s ide and rear co l­
li sio ns, in ro ll overs o r in cases whe re the re is not
eno ugh deceler ation th rough impac t to the front
of the vehicle . T he same goes for the other airbag
systems in your Audi. So, always wear your safety
belt and make sure everybody in your vehicle is
proper ly restrained!
Important safety instructions about safety
belts
Safety belts must always be correctly positioned
across the strongest bones of your body .
.,. Always wear safety belts as illustrated and de­
scribed in this chapter .
.,. Make s ure that your safety belts are always
ready fo r use and are not damaged .

_& WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds and/or by
being pushed into you as the airbag inflates.
- Always make sure nothing is in the front air-
bag deployment zone that could be struck
by the airbag when it inflates.
- Objects in the zone of a deploying airbag
can become projectiles when the airbag de­
ploys and cause serious personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the doors; never attach then to the doors or the wind­
shield; never place them over or near or at­
tach them to the area marked ,,AIRBAG" on
the steering wheel, instrument panel or the
seat backrests; never place them between
these areas and you or any other person in
the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music
players. Such objects could cause serious in­
jury in a collision, especially when the air­
bags inflate.
- Never recline the front passenger seat to
transport objects. Items can also move into
the deployment area of the side airbags or
the front airbag during breaking or in a sud­ den maneuver. Objects near the airbags can
fly dangerously through the passenger com­
partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
_& WARNING
A person on the front passenger seat, espe­ cially infants and small children, will receive
serious injuries and can even be killed by be­
ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front
-
Airbag system
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in
accordance with the ,,low risk" option for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child with electrical capac­
itance greater than the combined capaci­
tance of a typical one-year old infant re­
strained in one of the forward facing or rear­
ward-facing child seats with which your ve­
hicle was certified is on the front passenger
seat and the other conditions for airbag de­
ployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position .
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard 208 asap­
plicable at the time your vehicle was manufac­
tured.
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driver's and front passenger's heads and
upper bodies in frontal crashes. The airbags in­
flate only in frontal impacts when the vehicle de­
celeration is high enough.
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety
belts. Rather, it is part of the overall occupant re­
straint system in your vehicle. Always remember
that the airbag system can only help to protect
you, if you are sitting upright, wearing your safe-
ty belt and wearing it properly . This is why you ..,.

A WARNING
A child in a rearward-facing child seat instal ­
led on the front passenger seat wi ll be seri ­
ously injured and can be killed if the front air­
bag inflates -even with an Advanced Airbag
System.
-Although the Advanced Airbag System in
your vehicle is designed to turn off the front
airbag when a rearward-facing child re­
straint has been installed on the front pas­ senger seat, nobody can absolutely guaran­
tee that deployment is impossible in all con­
c eivable s ituations that may happen dur ing
the useful life o f you r vehicle.
- The inflating a irbag w ill hit the child seat or
infant carrier w ith great force an d will
smash the ch ild seat and child agains t the
backrest, center armrest, doo r, or roo f.
- Alw ays install rearward- facing child re­
straints on the rear seat .
- If you must i nst all a rearw ard facing child
sea t on the front passenger sea t beca use of
excep tional circ umstances and the
PASSEN­
GER AIR BAG OFF light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position
and have the a irbag system inspected by
your Audi dealer.
A WARNING
If, in exceptional c ircumstances, you must in­
stall a forward-facing ch ild restraint on the
front passenge r's seat:
-Always make sure the forward-fac ing seat
has be en designed and certified by its man­
ufact urer for use on a fro nt seat wit h a pas­
senger front and side airbag.
- Never put the forwa rd-facing child rest raint
up against or ve ry nea r the i nstr ument pan ­
el.
-Always move t he passenger seat into its
rearmost position in the seat 's fore and aft
adjus tment range, as far away from the air ­
bag as possib le, before installing the fo r­
ward-facing c hild restraint . The backrest
must be adjusted to an up right position .
-
Airbag syste m
- Always make sure that there is nothing on
the front passenger seat that w ill cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier than the person actually
sitt ing on the se at. T he presen ce of add i­
tion al ob jects could cause t he passenger
front airbag to be tu rned on when it shou ld
be off, or co uld cause the ai rbag to wo rk in a
way that is different from the way it would
have worked without the ob ject on the seat.
- Make sure that the
PASSENGER AIR BAG
OF F light comes on and stays on all the time
wheneve r the ignit ion is switched on.
Advanced Airbag System components
The front passenger seat in yo ur vehicle has a lot
of very impo rtant parts of the Advanced A irbag
System in it . T hese pa rts include the capacitive
passenge r detection system, wir ing, brackets,
and more. The con trol unit mon itors the syste m
o n the front passenge r se at when the ig nition is
swi tched on and turns the airbag indicator ligh t
on when a malfunction in the one of the system
components is detected
¢ page 160 . Because
the front passenger seat contains important
parts of the Advanced A irbag System, yo u m ust
take care to prevent it from being damaged.
Damage to the seat may prevent the Advanced
Airbag System for the front passenger seat from
doing its job in a crash.
The front Advanced Airbag System consi sts
of the following:
- Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
p rov ide i nfo rmat ion to the Advanced Airbag
System abo ut the sever ity o f the cr ash.
- An elect ron ic cont ro l unit, with integrated
cr ash senso rs for front and s ide imp acts. The
cont ro l uni t "dec ides" whet her to fire the fron t
airbags based on the info rmation received from
the crash sensors . The control unit a lso "de ­
cides" whether the safety belt pretens ione rs
should be activated. ..,.
