that you are developing enough driving force at
the wheels by depressing the accelerator .
Depending on the weight of the r ig (vehi cle and
tra iler) and the severity of the incline, you may
ro ll backwards as you start . You can prevent roll
ing backwards by holding the parking brake
switch pulled out and accelerating -just as you
wou ld when starting on a hill with a conventiona l
h and brake .
Emergency braking
In the event that the conven tional brake system
fails or locks .
~ In an emergency, pull the sw itch and cont inue
to pull it to slow your veh icle down with the
parking b rake.
~ As soon as you release the switch or accelerate,
the b raking process stops .
If you pull the sw itch and hold it above a speed of
about 5 mph (8 km/h) , the eme rgency braking
function is in it iated . The vehicle is braked at all
four wheels by activating the hydraulic brake sys
te m. T he b rake perfo rman ce is sim ila r t o making

sounds w hen the sw itch is p ulled. As soon as t he
sw itch is rele ased, or the acce le ra to r p edal is de
p ressed, eme rgency bra king stops.
A WARNING
Emergency bra king should only be use d in an
emergency, w hen the normal foot brake has
fai led or the bra ke pedal is obstructed . Using
the par king b rake to perfo rm emergency
brak ing will slow your vehicle down as if you
had made a full bra ke ap plication . The laws of
physics cannot be suspended even wi th ESC

Intelligent Technology
Hill descent assist
The hill descent assist makes it possible to drive
down an incline at a constant speed .

Fig. 188 Display: hill descent assist
.. Press the~ button in the center console
¢ fig . 187 or on the shift gate . The button will
illuminate .
" Press the button again to switch it off. The di-
ode in the button will go out .
Hill descent ass ist brakes all four wheels auto
matically in order to limit speed when driving ei
ther forwa rd o r reverse on hills with a grad e up to
approximately 50%.
When the hill descent assist is on, the current
driving speed, when your vehicle entered the in
cline is maintained.
It is only possible to switch
on the assist when driving slower than 37 mph
(60 km/h). The assist works between app roxi
mately 2 and 19 mph (4 and 30 km/h) . The driver
can increase or decrease the vehicle speed within
these limits by depressing the accelerator or
brake pedal In addition, vehicle steerability is in
creased due to the braking distribution when
driving in reverse .

There must be however sufficient ground adhe
sion . The hill descent assist can
not do its job if
the incline is icy or if the incl ine ground is loose
¢ &.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h). The system is
then in the ready-mode. The diode in the button
will come on . The system automatically sw itched
off when you drive faster than 37 mph (60 km/ h) . The diode will go out in this case .
Active control at a specific speed up to approxi
mately 19 mph (30 km/h) will appear in the in
strument cluster display
c:> fig. 188 . Two dashes
" •• " w ill appear in the ready mode .
Hill descent assist is automatically activated un
der the following conditions:
- the diode in the button illuminates,
- veh icle speed is below approximately 19 mph
(30 km/h)
- the incline is 10%.
& WARNING
-Always adapt your speed to the weather,
road and traffic cond itions. Do not let the
increased safety provided tempt you into
taking risks.
-
-The hill descent assist system cannot over
come the laws of phys ics. Your driving style
must always be adapted to the current road
and traffic conditions.
- The hill descent assist may not be ab le to
hold your vehicle at a constant speed under
all cond itions wh ile driving on an incline (for
example if ground under the vehicle is
loose).
Braking

brake. This may cause the brakes to over
heat, premature wear and increased stop
ping distance.
- Under certain climatic and operating condi
tions such as passing through water, driving
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re duced . In winter, ice can accumulate on the
brake pads, linings, discs and drums. Care
fully apply brakes for a test. Brakes will dry
and ice coatings 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 braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few carefu l
brake app lications .
-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 obstructed. Other
wise the brake system could overheat reduc ing the effectiveness of the entire brake sys
tem .
- Failure of one brake circuit will impair the
braking capability resulting in an increased
stopping distance. Avoid driving the vehicle and have it towed to the nearest author ized
Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lack of booster
assista nee.
Electromechanical power

The electromechanical power assist helps the
driver when steering.
Power steering adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defective! Do not drive vehicle!
194 If
this indicator light turns on and stays on and
this message appears, the power steering may
have failed.
Stop the vehicle in a safe location as soon as pos
sible. Do
not continue driving . See your author
ized Audi dealer or other qualified repair facility
for ass istance .
'-r, ij Dynamic steering: System fault! You can
continue driving
If the indicator l ight turns on and the message
appears, the steering may be more difficult to
move or more sensitive than usual. The steering
may also be at an angle when driving straight.
Drive slowly to your authorized Audi dealer or
qualified workshop to have the malfunct ion cor
rected.
1 :r- ij Dynamic steering: Initializing
Audi drive select* : if the indicator light blinks and
the driver message appears, the dynamic steer i ng* is reinitial ized. After start ing the engine, the
steering wheel will move slightly . Re-initial iza
tion might be necessary if the steering wheel was
moved hard to the left and right while the vehicle
was not moving. The display turns off if the initi
alization was successful.
(D Tips
- If the . or 1:r- ij in dicato r light only stays on
for a short time, you may continue driving.

General information
With all-wheel drive, power is distributed to all
four wheels. This happens automatically depend

The all-wheel drive concept is designed for high
engine power. Your ve hicle is exceptionally pow
erful and has excellent driving characterist ics
both under norma l dr iving condit ions and on
snow and ice. Always read and follow safety pre
cautions ¢.&. .
Winter tires
When driving in the w inter, your vehicle with a ll
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be adv isa
b le to mount w inter t ires (or all-season tires) for
i mproved driveab ility and brak ing : these tires
must be mounted on
all four wheel s. See a lso
¢ page 249, Winter tires.
Tire chains
Where tire chains are manda tory on certain
roads, this normally also applies to vehicles w ith
a ll-wheel drive¢ page 249 , Snow chains.
Replacing wheel s/tires
Veh icles with all -whee l dr ive must always have
tires of the same s ize. A lso avo id tires with differ
ent tread depths . For detai ls see page
¢ page 241, New tires or wheels.
A WARNING
Always adjust you r driving to road and t raff ic
conditions. Do not let the extra safety affo rd
ed by all-wheel drive te mpt you into tak ing
extra risks.
- Alt hough the all-whee l dr ive is very effec
t ive, always remember th at br akin g ca pac ity
is limited by tire traction. Yo u should t here
fore not d rive at excess ive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be caref ul not to drive
too fast because the front wheels co uld be
gin to slide on top of the water (a quaplan
ing). If this shou ld occu r, you w ill have no
warning from a sudden increase in eng ine
speed as with a front -whee l dr ive vehicle.
Intellig ent Technology
Always d rive at speeds which are suited to
the road conditions -risk of c rash.
Energy management
