.&_ WARNING
Improper use of steer ing whee l adjustment
and improper seating position can cause ser i­
ous pe rsonal injury.
- Adjust the steer ing whee l co lumn on ly w hen
the vehicle is not mov ing to prevent loss of
vehicle control.
- Adjust the driver's seat or steering wheel so
that there is a min imum of 10 inches (25
cm) betwee n your chest and t he s teer ing
wheel
~page 96, fig. 107 . If you cannot

Drivi ng
maintain t his minim um distance, the airbag
system cannot p rotect yo u proper ly.
- If physical limitations prevent you from sit­
ting 10 inches (25 cm) or more from the
steer ing whee l, check with your author ized
Audi dealer to see if adaptive equipment is
ava ilable.
- If the steer ing whee l is aligned w ith your
face, the supplementa l driver's a irbag can­
not provide as much protect io n in an acc i­
dent. Always make sure that the steer ing
wheel is aligned with you r chest.
- Always hold the steering wheel w ith your
hands at the 9 o'clock and 3 o' clock posi­
tions to reduce the risk of pe rso nal injur y if
the dr iver's a irbag dep loys .
- Never ho ld the stee ring wheel at the 12
o'cl ock position or wi th you r hands inside
the stee rin g wheel rim or on the s teer ing

the parking brake releases automatically and the
vehicle starts to move.
Starting on hills
When start ing on inclines, the hill start ass ist
prevents the vehicle from unintentionally roll ing
back. The braking force of the parking brake is
only released if sufficient drive power has been
bui lt up at the whee ls.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is fastened and the driver's door is
locked.
Starting to drive with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
.. Keep pulling the<®> switch and press the acce l­
erator pedal. The parking brake stays applied
and prevents the vehicle from ro lling backward.
.. You can re lease the<®> switch once you are sure
that you are transferring enough dr iving force
to the whee ls by pressing the accelerator pedal.
Depending on the weight of the rig (vehicle and
trailer) and the severity of the incline, you may
roll backwards as you start.
Hill hold
A ppl ies to vehicles: with H ill Hol d
Hill hold makes it easier to start on hills .
Requirement: The driver's door must be closed,
the seat belt must be buckled and the engine
must be running.
The system is activated when the brake pedal is
p ressed
for a few seconds.
To prevent the vehicle from roll ing back when
starting, the brake power is held for a brief mo­
ment after releasing the brake pedal. During this
~ time, you can easi ly begin to move you r vehicle .
ci ::, co ,...., N Driving
A WARNING
- The intelligent technology of Hill Hold can­
not overcome the limitat ions imposed by
natural physical laws. The increased comfort
offered by Hill Hold should not cause you to
take safety risks.
- Hill Hold cannot hold the vehicle in all hill
start situations (for example, if the g round
is slippery or icy).
- If you do not beg in moving immediately af­
ter releasing the brake peda l, the vehicle
could begin to roll backward under certain
circumstances . Press the brake pedal or set
the parking brake immediately.
-If the engine "stalls", press the brake pedal
or set the parking bra ke immediate ly.
- To prevent the vehicle from roll ing back un­
intentionally when starting in s top-and-go
traffic, keep the brake pedal pressed for a
few seconds before driving off .
(D Tips
You can find out if your vehicle is eq uipped
wi th Hill Hold by checking at an authorized
Audi dealer or authorized Audi Service Facili­
ty.
Emergency braking function
This is used if the conventional brake system
fails or locks up.
.,. To brake your veh icle using the parking brake in
an emergency, pu ll the(®) switch and keep it
pulled.
.. The braking stops as soon as you release the<®>
switch or acce lerate .
If you pu ll the(®) switch and hold it above a
speed of about 5 mph (8 km/h) , the emergency
braking function is activated. The vehicle brakes
at all four whee ls by activating the braking hy­
draulics. The brake performance is similar to
heavy brak ing .

A WARNING
- The vehicle can also ro ll when the eng ine is
stopped.
- Unintended vehicle movement can cause se­
rious injury.
- Never leave your veh icle with the engine
running while in gear. If you must leave
your veh icle w hen the engine is r unning, ac­
tivate t he pa rking brake a nd move the selec­
tor lever to P .
- Power is still transmitted to the wheels
when the engine is running at idle . To p re­
vent the vehicle from "creeping", yo u m ust
keep your foo t on t he b rake when the en­
g in e is ru nning and the selector lever is in D/
Sor R or "tiptronic" mode is se lected .
- Do not press the a cce le ra to r peda l when
changing the se lec to r l ever posi tion while
the vehicle is s ta tionary and the engine is
r u nning .
- Never sh ift into R or P whi le driving.
- Before d riving down a s teep sl ope, redu ce
your spee d and sh ift into a lower gea r w ith
"t i ptronic" .
- Do not ride the brakes or press the bra ke
pedal too of ten o r too long when dr iv ing
down a hi ll. Constant braking ca uses the
brakes to ove rheat and substantially re­
duces brak ing performance, increases b rak­
ing d istance or causes comp lete failure of
the brake system.
- To prevent the veh icle from rol ling back
when stopp ing on inclines, always hold it in
place with the brake peda l or park ing brake .
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An ind icator lam p. illumina tes

Intelligent Technology
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 approxi­
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.
There must be however sufficient ground adhe ­
sion . The hill descent assist
cannot do its job if
the incline is icy or if the incline ground is loose
¢ ,&.
Active assistance at a specific speed up to about 19 mph (30 km/h) is shown in the instrument
cluster through a blinking indicator light •. The
indicator light shines continuously when in the
ready mode.
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. This is shown through
the LED turned on in the button . The system au­
tomatically switched off when you drive faster
than 37 mph (60 km/h). The LED will also go out
in this scenario.
Hill descent assist is automatically activated un­
der the following conditions:
- The LED in the button turns on ,
- the vehicle speed is lower than 19 mph (30 km/
h) ,
-the incline angle is at least around 10% .
A WARNING
-Always adapt your speed to the weather ,
road and traffic conditions . Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident.
- The hill descent assist system cannot over­
come the laws of physics. Your driving style
must always be adapted to the current road
and traffic conditions.
- The hill descent assist may not be able to
hold your vehicle at a constant speed under
all conditions while driving on an incline (for
154
example if ground under the vehicle is
loose).
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first
250 mi (400 km). They
must be "broken in" first¢& . However, you can
compensate for the slightly reduced braking
force by pressing firmly on the brake pedal. Avoid heavy braking during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear, depending largely on operating con­
ditions and driving habits¢,& . On vehicles that
are either driven mostly in stop-and-go city traf­
fic or are driven hard, the brake pads should be checked by your authorized Audi dealer more of ­
ten than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the braking ef­
fect of the engine. This way, you prevent unnec­
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin­
uously. Pump the brakes at intervals.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water or road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con­ densation or after washing your car , the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica­
tions.
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 .,.

Fig. 143 Permitted ball pos ition of the trailer hitch
Trailer towing weights
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissib le trailer weight is
2,200 lbs (1,000 kg). The maximum permiss ible
unbraked trailer weight is 1,650 lbs (750 kg).
These specifications apply when dr iv ing on roads
h av ing an incl ine of less than 12%.
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maximum allowable or
slightly lower. You can get an approximation of
the tongue load w ith a bathroom scale o r you can
measure the load at a trucking company or
weighing station.
With a
factory-installed or an aftermarket trailer
hit ch, the maximum permissib le load on the ball
hitch may not exceed 220 lbs (100 kg).
It is rec­
ommended to use the maximum permissible
l oad.
Trailer load distribution Be sure the load in the trailer is held securely in
place to prevent it from s hiftin g forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer ¢.&.
in Driving instructions on page 166.
Ball mount
The trailer hitch may only be used w ith suitable
ball mount and ball¢
fig. 143. Installation of
the hitch ball must be carr ied out in accordance
with the manufacturer's instructions.
Trailer mode
Engine cooling system
To wing a trailer makes the engine work harder. It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure that
the cooling system has enough fluid .
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to th e cold tire pressure lis ted under "Full
load" on the tire pressure label. The tire pressu re
label is located on the driver's side B-pi llar . In­
flate trailer t ires to trailer and tire manufactur­
ers' specifications.
Lights
T he headlight settings shou ld be checked with
the trai ler attached before driving off. Check to
make s ure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough s lack in the chains to permit turn ­
ing corners . When you install safety chains, make
sure they will not drag on the road when you are
driv ing.
The chains should cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with o trailer always requires extra core
and consideration .
To obtain the best possib le handling of vehicle
and trailer, p lease note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded.
.. Be especially care ful when passing other
vehicles .
.. Observe speed limits.
.. Do not drive at the maximum permissib le
speed.
.. Always apply brakes early.
.. Mon itor the temperature gauge .
