Tie-downs
The luggage compartment is equi pped with f our tie­
downs to secur e luggage and other items.
Use the t ie-downs to sec ure yo ur cargo prope rly => page 183,
"Load ing the luggage compartment" .
In a co llision, the laws of physics mean that even sma ller items that
are loose i n the vehicle will become heavy m issiles t hat can c ause
serious injury. Items in the vehicle possess energy wh ich vary w ith
vehicle speed and the we igh t o f the i tem. Vehi cle spee d is t he m ost
significant factor.
For examp le, in a frontal coll ision at a spee d of 30 mph (48 km/h),
the forces acting on a 10- lb (4 .5 kg) object are abo ut 20 times the
normal weight of the item . T his means that t he weight of t he item
wou ld s uddenly be abo ut 200 lbs. (90 kg). You can imagine the inju­
r ies that a 200 lbs . (90 kg) item flying free ly throug h the passenge r
c ompa rtmen t cou ld cause in a collision lik e this.
& 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 personal injury .
• Always use suitable mounting strap s and prope rly secure items
to the tie -downs in the luggage compartment to help prevent
items from shifting or flying forward as dangerous missiles.
• When the rear seat backrest is folded down, always use suit­
able mounting straps and properly secure items to the tie-downs

open an investig ation, and if it find s that a
safety d efe cts exist s in a group of vehicle s, it
ma y order a rec all and remedy campaign.
However , NHTSA cannot become involved in
individual problems between you , your dealer,
or Audi of America , Inc.
To contact NHTSA , you may call th e Vehicle
Safety Hotline toll-free at:

fore-and-aft and lateral directions, the brake pressure and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continually
compared with the actual behavior of the vehicle. If the two do not
match, for example , when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate wheel to correct
the problem.
The vehicle is then stabilized by the forces acting on the wheel during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are mainly applied on the wheel that is on the
outside of the curve. In the case of a vehicle that is
understeering
(tendency to slide out of the curve), the brakes are applied at the rear
wheel that is on the inside of the curve. An acoustic signal indicates
when ESP brake application cuts in =>
&.
The system operates across the entire speed range in combination
with the ABS system=>
page 246. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
will perform a self-test . As soon as the test is completed, the system
is in normal operating mode.
You can activate a deactivated ESP or deactivated ESP/ ASR if required
by pressing the=>
page 242, fig. 201 button. When they are acti­
vated, the message
ESP/ASR on appears briefly in the display .
Deactivating
The ESP should normally be activated all the time. If necessary , you
can deactivate Anti-Slip Regulation (ASR) or the Electronic Stabiliza­
tion Program (ESP) by pressing the button =>
page 242, fig. 201.
• Deactivating ASR: Tap the but ton . In certain excep tional situa­
tions (e.g. driving with tire chains) , the Anti-Slip Regulation (ASR) can
be deactivated=>
page 244 . The message ASR off appears in the
display as well.

Deactivating ESP/ASR
Press the button for more than 3 seconds .
With the ESP/ASR deactivated, the ESP check light comes on, see
=>
page 14. The message ESP switched off appears in the display as
well.
& WARNING
The Electronic Stabilization Program is nevertheless subject to the laws of physics. It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and traffic conditions. Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDL) helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or almost
no grip . Without EDL, this would be difficult, if not impossible .
How the system works
The EDL operates automatically . It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=>
page 246 . If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power to
the othe r drive wheel or wheels (all-wheel drive). This is done up to a
speed of about 60 mph (100 km/h) . Noises from the brake system
signal that wheel spin is being controlled.

Low brake fluid l evel
Ma lf u nctions can occ ur in the brake system if the brake fluid level is
too low . T he brake flu id level is monitored e lec tron ically .
Brake lining wear statu s
Brake lining wear may be checked by visua l inspection of the condi­
t ion of t he brake pads through the open ings in the whee l. If neces ­
sary, the wheel may be removed fo r thi s inspection~
page 320,
"Changing a whee l".
& WARNING
• You should p erform braking maneuvers for the purpo se of
cleaning the brake system only if road condit ions permit. Other
road u sers must not be put at risk - you may cau se an accident!
• Befo re descending a steep grade, reduce speed and sh ift t rans ­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often. Th is could
cause the brake s to get hot and diminish braking efficiency.
• Do not "ride the b rakes " by resting your foot on the pedal when
you do not intend to brake. Thi s may cau se the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced. In winter ,
ice can accumulate on the brake pads , linings, discs and drums.
Carefully apply brakes for a test. Brake s will dry and ice coating s
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can also affect brak ing efficiency. Clean
off accumulated salt co ating from brake disc s and pads with a few
careful brake applications.
• If you damage the front spoiler , or if you in stall a different
spoiler , be sure the air flow to the front brakes is not obst ructed.
Otherwi se the brake system could overheat reducing the effective­
ness of the entire brake system .
& WARNING (c on tinued )
• Failure of one brake circuit will impair the braking capability
resulting in an increa sed stopping di stance. Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop. •
Brake booster
The brake booster adds extra brakin g po wer.
Th e bra ke booster wor ks with vacuu m pressure which is created on ly
when the eng ine is running ~& .
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working , for e xample when towing
y our vehicle , or be cause the brake booster has somehow been
damaged , the brake pedal must be pressed considerably harder to
make up for the lack of boo ster assistance. •
Functioning of Anti-Lock Brake System
(ABS)
AB S prevents the wh eels from locking up under braking .
The ABS co ntrib utes effe ctive ly to ve hicl e con tro l s in ce i t preven ts t he
wheels from
locking when the brakes are applied . This means that the
vehicle remains steerable and is less likely to s kid.
With ABS you do not need to pump the brake. Just hold the brake
pedal down.
However, do not expect t he A BS to sho rten b raking di stan ce u nder all
circumstances. W hen driving on grave l or on newly fa llen snow on top
of icy s urfaces, braking distance may be even longer, therefore, under .,_

• Never try to remove dirt, mud o r d ust if the s urface of the vehicle
is dry. Never use a dry cloth or sponge, s ince this could scratch your
veh icle's pai nt o r win dows.
• Never was h your car in bright sunlight . D rops of water act as
magnifyi ng lenses and may damage your p aint.
• When you was h yo ur car in the winter: if you rinse your vehicle w ith
a hose , be careful not to a im the stream of wate r d irect ly at locks, or
at doo r or hatch openings -they can freeze s hut.
• N ever use sponges des igned to remove insects, o r any kitchen
sco uring sponges or s imilar pro ducts. They can damage yo ur paint
fi ni sh.
• N ever use a dry cl oth o r sp on ge to clean t he he adlig hts. Only use
wet cloths or sponges to prevent scratches . It is best to use soapy
water .
For the sake of the environment
In the interest of the environme nt, the ve hicl e should on ly be washed
in special wash bays. •
