When the light comes on, an audib le warning
signal is also given .
.&_ WARNING
- Always observe the warnings in
¢ page 179, before opening the hood
and checking the brake fluid.
- Driv ing with low brake fluid is a safety
hazard. Stop the car and get professional
assistance.
- If the . (USA models) . (Canada
models) brake system indicator light
turns on together with the ABS and ESC
indicator lights, the ABS/ESC regu lating
function may have failed. Functions that
stabilize the vehicle are no longer availa­
ble. Th is could cause the vehicle to
swerve and increase the risk of sliding .
Drive carefully to the nearest a uthorized
Audi dealer or other qualified workshop
and have the malfunction corrected.
- If the brake warning/indicator light does
not go out after a few seconds and the
park ing brake is released, or lights up
wh ile you are driving, the fluid level in
the brake fluid reservoir is too low .
If you
believe that it is safe to do so, proceed
immediately at low speed to the nearest
authori zed Audi dealer o r qualified wo rk­
shop and have the bra ke system inspect­
ed.
- Always keep in m ind that after several
brake applicat ions, yo u will need greater
pressure on the brake peda l to stop your
vehicle. Do not re ly on strained brakes to
respond with maxim um stopping power
in critical situations. You must allow for
increased brak ing distances. The extra
distance used up by fad ing brakes could
lead to an acc ident.

belt warning light.
~- Steering column lock
• Steering fault! Do not drive vehicle!
If the indicator light turns on and the mes­
sage appears, there is an electronic steering
column lock malfunction. You cannot switch
the ign ition on.
Do
not tow your vehicle because it cannot be
steered . Seek professional assistance.
Ill Steering lock: System fault! Please con­
tact dealer.
If the indicator light turns on and the mes­
sage appears, there is an electronic steer ing
column lock malfunction.
Drive to your authorized Audi dea ler immedi­
ate ly to have the malfunction corrected .
A WARNING
-
Your vehicle must not be towed in the
event of a malfunct ion in the electron ic
steering column lock because it cannot be
steered due to the locked steering. If it is
towed with the steering locked, there is
the risk of an accident .
!;.IC; Electronic Stabilization Control
(ESC)
If the J;J indicator light blink s whi le driving,
the ESC or ASR (Anti-S lip Regulation) is active­
ly regulating .
If the: JjJ indicator light turns on, the system
has switched the ESC
off. In this case, you can
switch the ign ition
off and then on to switch
the ESC on aga in. The indicator light turns
off
when the system is functioning fully.
If the II indicator light turns on, ESC was re­
stricted or sw itched
off using the I~ OFFI but­
ton

Stabilization control (ESC/ABS): Fault! See
owner's manual
If the indicator l ight GJ and the ABS indicator
light
t1l1 (USA mode ls) ;tiJ (Canada models)
tu rn on and the message appears, the ABS o r
electronic differentia l lock is malfunctioning.
This also causes the ESC to malfunction. The
brakes still function with their normal power,
but ABS is not active.
Drive to your authorized Audi dealer immedi­
ate ly to have the ma lfunction corrected.
A WARNING "--
If the . (USA mode ls)/ . (Canada mod-
e ls) brake system indicator light turns on
together with the ABS and ESC indicator
lights, the ABS/ESC regulating function
may have failed. Functions that stabilize
the vehicle are no longer ava ilable. This
could cause the vehicle to swerve and in­
crease the risk of slid ing. Drive carefully to
the nearest authorized A udi dealer and
have the ma lfunction corrected.

72 On the road
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the follow ing:
.. Keep the switch@¢ page 70, fig. 77 pulled
and depress the accele rator. The park ing
brake stays applied and prevents the vehicle
from roll ing bac kward.
"' You can release the switch @ once you are
sure that you a re develop ing enough dr iv ing
f orce at the wheels by dep ress ing the accel­
erator.
Depending on the weight of the r ig (veh icle
and tra iler) and the seve rity of the in cli ne, you
may roll backwards as you start . You can pre ­
vent rolling backwards by holding the parking
brake switch @ pulled out and accelerating -
just as you would when starting on a hill with a conventional hand brake.
Hill hold
Hill hold makes it easier to start on hills.
Requirement : The driver door must be closed
and the engine must be r unning .
The system is act ivated when the brake pedal
i s pressed wh ile the veh icle is sta tionary .
To prevent the vehicle from rolling back when
start ing , the brake power is held for a br ief
moment after re leas ing the b rake peda l. Dur­
i ng th is t ime, yo u can easily begin to move
your ve hicle.
A WARNING
- The inte lligent technology of Hill Hold
cannot overcome the lim itations im­
posed by natural phys ica l laws. The in­
creased comfort offered by Hill Hold
should not cause you to take safety risks.
- Hi ll Hold cannot hold the veh icle in all
hill start situations (for examp le, if the
ground is slippery or icy).
- If you do not begin moving immediately
after releasing the brake pedal, the veh i­
cle could begin to roll backward under
certai n circumstances . Press the b rake
-
pedal or set the parking brake immedi­
ately .
- If the engine "stalls", press the brake
pedal or set the parking brake immedi­
ately .
- Starting on inclines in stop-and-go traf­
f ic: To help prevent the vehicle from roll­
ing back when start ing, press and ho ld
the brake pedal for several seconds when
the vehicle is stationary.
Emergency braking
In the event tha t the conventional brake sys­
tem fails or locks .
.. In an emergency, pu ll the switch @
¢
page 70, fig. 77 and continue to pull it to
slow your vehicle down with the parking
brake .
.. As soon as you release the switch @ or ac-
celerate, the b rak ing process stops.
If you pull the switch @ and hold it above a
speed of about S mph (8 km/h), the emergen­
cy brak ing funct io n is initiated . T he veh icle is
braked at all fou r whee ls by activating the hy­
draulic b rake system. The brake pe rfo rmance
is sim ila r to m akin g an emergency stop ¢_&. .
In order not to act ivate the eme rgency brak­
ing by mistake, an audib le warning tone (buz­
zer) sounds whe n the switch @ is pulled. As
soon as t he sw itch @ is re leased, or the acce l­
erator pedal is depressed, eme rgency braking
stops.
A WARNING
=
Emergency braking should only be used in
an emergency, when the norma l foot bra ke
has fa iled or the brake pedal is obstructed.
Using the park ing brake to perform emer­
gency braking will s low your veh icle down
as if you had made a full brake application .
The laws of phys ics cannot be suspended
even with ESC and i ts associa ted compo­
nents (ABS, ASR, EDS). In corners and
when road or weathe r cond itions are bad
,

Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­
erly stowed and secured in the luggage com ­
partment.
Fig. 105 S afe load pos itio nin g: place heavy objects as
low a nd as far forward as possible .
Loose items in the luggage compartment can
shift suddenly, changing vehicle hand ling
characteristics. Loose items can also increase
the risk of serious personal injury in a sudden
vehicle maneuver or in a collision .
.. Distribute the load evenly in the luggage
compartment .
.. Always place and properly secure heavy
items in the luggage compartment as low
and as far forward as possible
c> fig. 105.
.. Secure luggage using the tie-downs provid­
ed
c> page 60.
.. Make sure that the rear seatback is securely
latched in place .
A WARNING
Improperly stored luggage or other items
can fly through the vehicle ca using serious
personal injury in the event of hard brak ­
ing or an accident. To help reduce the r isk
of serious personal injury:
- Always put objects, for examp le, luggage
or other heavy items in the luggage com­
partment.
- Always secure objects in the luggage
compartment using the tie-down eye lets
and suitable straps.
A WARNING
-Heavy loads will influence the way your ve-
hicle handles. To help reduce the risk of a
loss of control leading to serious personal
injury:
-Always keep in mind when transporting
heavy objects, that a change in the cen­
ter of gravity can also cause changes in
veh icle handling :
- Always distribute the load as evenly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­
missible weight standards can cause the
veh icle to slide and handle differently.
- Please observe information on safe driv­
ing
c> page 94.
A WARNING
-
To help prevent poisonous exhaust gas
from being drawn into the vehicle, a lways
keep the rear lid closed while driving.
- Never transport objects larger than
those fitting comp letely into the luggage
area because the rear lid cannot be fully
closed .
- If you absolutely m ust dr ive with the rear
lid open, observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the Panoramic sliding sunroof *,
- Open all air outlets in the instrument
pane l,
- Switch off the air recirculat ion,
- Set the fresh air fan to the highest

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 107 Unbelted occupants in a ve hicle heading for a
wall
Fig. 108 The vehicle cras hes into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
ergy."
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
SO km/h), the energy increases 4 t imes!
Because the passengers of this vehicle are not
using safety belts¢
fig. 107, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them - here, the wall ¢
fig. 108.
Safety belts 105
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 (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 colli­
sion 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 app ly to frontal collisions, they determine
what happens in all kinds of accidents and col­
lisions.
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!

t hrown forward

Unbelted occupants are not able to resist the
tremendous forces of impact by holding tight
or bracing themselves . Without the benefit of
safety restraint systems, the unrestrained ..,_
