Driving
-The parking brake goes through a se lf -test
cycle at regular intervals when the vehicle is
stopped . Any noises associated w ith this are
normal.
- If there is a power failure , the parking brake
will not set if it is re leased, and it will not
release if it is
set¢,&. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for ass istance .
Starting to drive
Various convenience and safety functions may be
ava ilable when the vehicle begins driving , de ­
pending on vehicle equipment.
Starting on hills with the parking brake set
Requirement: the doors must be closed and the
driver's safety belt must be fastened .
~ To start driving comfortably when on a hill, set
the parking brake and begin driving as usual.
The braking force of the parking brake does not
release automatically until the wheels build up
enough dr iv ing force .
Starting on hills with hill hold assist
Hill hold assist makes it easier to start on hills .
Requirement: the driver's door must be closed
and the engine must be running.
~ To activate hill hold assist, press and hold the
brake peda l for several seconds. The veh icle
must be in an uph ill direction of travel.
After releasing the brake pedal, the brak ing pow ­
er is ma intained for a brief
moment ¢.& to pre­
ve nt the vehicle from rolling back when starting.
During this time, you can easily beg in to move
your ve hicle.
A WARNING
-If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your vehicle may begin to roll back­
ward . Press the brake pedal or set the park­
ing brake immed iate ly.
- The intelligent techno logy of hill hold assist
cannot overcome the limitations imposed by
82
-
natural physica l laws. The increased comfort
offered by hill hold assist should not cause
you to take safety risks .
- Hill hold assist cannot hold the vehicle in
place on all hills (for examp le, if the ground
is s lippery or icy).
- To reduce the r isk of an accident, always
make sure the veh icle is situated safely
while stationary .
Off road driving
General information
The Electronic Stabilization Control (ESC) func­
tions were enhanced for driving offroad. Offroad
mode can be activated when driving in situations
where slippage or a differential lock function is
necessary ¢ page 141. The hill descent assist is
also available, wh ich automatically brakes the ve­
hicle to maintain a constant speed
¢ page 142 .
In add it ion, your Audi provides cont inuous all
whee l drive .
However, your Audi is not a purely offroad vehi­
cle . Your vehicle was not designed to dr ive under
extreme operating conditions such as driving in
an expedition style.
Only drive on terrain that is suitable for the ve­
hicle and your driving ability. Never take any
unnecessary risks!
Before driving offroad
- Check the engine oil level, the tire pressure, the coo lant level and the fluid level in the washer
fluid reservoir.
- Store pieces of luggage and other objects in the
luggage compartment and secure them from
sliding out of place .
After driving offroad
-After driving offroad, remove branches and
other debris from the radiator grille, under­
body, and wheels. Look especially for foreign
objects (such as s tones) that may be stuck in
the t ire tread .
- Clean the vehicle body and underbody and in-
spect the vehicle for possible damage .

Wear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy rain or after washing
your car, the braking effect may be reduced due
to moisture or ice on the brake rotors and brake
pads. The brakes must be "dried" first with a few
careful brake applications.
At higher speeds and with the windshield wipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather.
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at high speeds is recommended to clean the brake
rotors and
pads¢ ,&..
Brake system malfunction
If you notice that the brake pedal travel has sud­
denly increased, then a brake circuit in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
Intelligent Technology
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake pedal harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
is electronically monitored.
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
& WARNING
= -
- Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users. This increases the
risk of an accident.
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
- Never place objects in the driver's footwell.
An object could end up in the area around
the pedals and prevent you from using
them. You would not be able to use the ped­
als if sudden driving or braking maneuvers
were needed, which increases the risk of an
accident.
- Only use floor mats that do not obstruct the
area around the pedals and that can be se­
curely fastened in the footwells.
- To reduce the risk of injury, do not place
your foot under the brake pedal.
@ Note
- Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking distance and
causes wear.
- Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to brake additionally, brake in in- tervals and not continuously.

R ati ng
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs . (68 kg) for each passen­
ger at a designated seating posi ­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gro ss Ax le W eight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
T he fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen -

gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rat ing
are listed on the safety compli­
ance sticker labe l located on the
driver's side B-pillar.
1.8. WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud ­
denly, including a blowout and
sudden deflation, causing loss
of contro l and a crash.
