more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries .
-Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
cou ld be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
-For safety reasons, always park the vehicle
with the selector lever in the P position .
Driving
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off .
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following
reasons :
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­

Automatic transmission
Introduction
The automat ic transmission is controlled e lec­
tron ica lly. Power is transferred using a torque
converter.
The transm ission shifts up or down automat ically
depending on wh ich drive program is selected.
When a
mod erate driving s tyle is used, the
transmission selects the most e conomical d riving
mode. The t ransm iss ion upsh ifts at a lower RPM
and downshifts at a highe r RPM to imp rove fuel
efficiency.
The transm ission switches to a spor ty mode after
a kick-down or when the driver uses a
sp o rt y
driving style
c haracterized by quick accelerator
pedal movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the dr iver can also select the gears
manually (tiptronic mode)

Driving
keep your foot on the brake in all selector
lever positions (except P and N) when the
engine is running.
- Do not inadvertently press the accelerator
pedal when the vehicle is stationary. Other­
wise the vehicle will start to move immedi­
ately, even if the parking brake is set. This
could result in a crash.
~ Note
-When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­ lected . This can cause the transmission to
overheat and can damage it . Set the parking
brake or press the brake pedal to prevent
the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped will damage the transmission be­
cause it is not lubricated.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is fastened.
Hill descent control
The hill descent control system assists the driver
when driving down hills .
Hill descent control activates when the transmis­
sion is in the Dor S position and you press the
brake pedal. The transmission automatically se­
lects a gear that is suitable for the hill. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical and
technical limitations. If may still be necessary to
adjust the speed with the brake pedal.
Hill descent control switches off once the hill lev­
els out or you press the accelerator pedal.
When operating the cruise control system
c::> page 93, hill descent control is also activated
when the speed is set.
86
A WARNING
, -
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes .
Manual shifting
The shi~ paddles allow the driver to shift the
gears manually.

.,. To switch manual mode off, press the ['.fl but-
ton again, or
.. Move the selector lever back and release it.
When you accelerate or reduce the speed, the
transmission automatically shifts into the correct
gear shortly before reaching the RPM limit. If you
select a lower gear than the one currently shown
in the display, the automatic transmission will
only shift down once there is no danger of ex­
ceeding the maximum RPM.
The engine braking effect increases when you
downshift when going downhill.

General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­ my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trailer, you must ac­
tivate the trailer operation mode
c:> page 89, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a
technically
sound
location . Use only a trailer hitch with a re­
movable ball mount. Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bolts remain securely fastened.
When you are not towing a trailer, remove the trailer hitch ball mount . This prevents the hitch
from causing damage should your vehicle be
struck from behind
£:=? .&, .
Trailer towing
Trailer brakes
If your trailer is equipped with a braking system,
check to be sure that it conforms to all regula­
tions.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system.
Safety chains
Always use safety chains between your vehicle and the trailer.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check with your Audi dealer for correct wiring,
switches and relays .
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear .
.,&. WARNING
-After removing the trailer hitch, do not store
it in your vehicle. In case of sudden braking,
the hitch could fly forward and injure you or
your passengers.

-
-Always pay attention to the traffic around
you when the cruise control system is in op ­
eration. You are always responsible for your
speed and the distance between your vehi­
cle and other vehicles.
-For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
risk of an accident.
-Switch the cruise control off temporarily
when driving in turning lanes, highway exits or in construction zones.

Assistance systems
-Please note that unconsciously "resting"
your foot on the accelerator pedal prevents
the cruise control from braking. This is be­
cause pressing the accelerator pedal over­
rides the cruise control system.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off. The rest of
