_& WARNING
- Never a llow the engine to run in confined
spaces - there is a risk of asphyxiation .
- Never remove the ignit ion key from the
ignition loo k while the vehicle is moving .
Otherwise the steering lock will engage
and you will not be able to steer the vehi­
cle.
- Please note that the b rake booster and
power steering only work when the en­
gine is running. When the engine off, you must use more force to steer or brake
the vehicle. Because the usual steer ing
and brak ing capability is not ava ilable,
the risk of accidents or injur ies increases .
- Always take the vehicle key with you when leav ing the vehicle, even for a
short pe riod of time. This applies part ic­
ularly when children remain in the veh i­
cle. Otherwise the chi ldren could start
the engine or operate electrical equip ­
ment such as power w indows.
(D Note
- Avo id h igh engine speed, full th rottle,
and heavy eng ine load as long as the en­
gine has not reached operat ing tempera ­
t u re yet . You could damage the engine.
- T he engine cannot be started by pushing
or towing.
@) For the sake of the environment
Do no t let the eng ine run w hile pa rked to
warm up. Begin dr iv ing immediately. This
reduces unnecessary emissions.

must use more force to steer or brake
the vehicle. Because the usual steering
and braking capability is not available,
the risk of accidents or injuries increases .
- Avoid high engine speed, full throttle,
and heavy engine load as long as the en­
gine has not reached operating tempera­
ture yet. You could damage the engine .
- The engine cannot be started by pushing
or towing.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.
{D) Tips
- After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must first build up in the hydraulic valve adjusters. This is
normal and not a cause for concern .
- If the . indicator light blinks in the in­
strument cluster before switching the ig ­
nition off, the ignition will not switch on
again.
9 page 193
- If you leave your vehicle with the ignition
switched on, the ignition will switch off
after a certain amount of time. Make
sure that electrical equipment such as
the exterior lights are switched off.

briefly or press and hold for longer than two
seconds.
A WARNING ~
- Never turn off the engine before the ve- hicle has come to a complete stop . The
full function of the brake booster and the
power steering is not guaranteed . You
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injuries.
- Please note that the brake booster and
power steering only work when the en­
gine is running. When the engine off, you
must use more force to steer or brake
the vehicle. Because the usual steering
and braking capability is not available,
the risk of accidents or injuries increases.
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time. This applies partic­
ularly when children remain in the vehi­
cle . Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
- For safety reasons, always park the vehi­
cle with the selector lever in the P posi­
tion. Otherwise, there is the risk that the
vehicle could roll.

the dr iving condit ions by hand
¢ page 114.
When parking on a level surface, simply place
the selector lever in the P pos ition. On in­
clines , activate the parking bra ke first and
then move the selector lever to the P pos it ion
¢ page 80 . This prevents the locking mecha­
nism from being loaded too heavi ly and will
make it easier to move the selector lever out
of the P position.
A WARNING
- The vehicle can roll even when the en­
g ine is switched off.
- Unintended vehicle movement can lead
to serious injuries .
- Never leave your vehicle with the engine running while in gear. If you must leave
your veh icle when the engine is running,
set the parking brake and move these­
lector lever to the P position .
- Power is still transferred to the wheels
when the engine is runn ing at idle. To
prevent the vehicle from "c reeping", you
must keep you r foot on the brake when
the engine is running and the selector lever is in the D, Sor R position or "tip­
tronic" mode is selected . -
-Do not inadvertently press the accelera­
tor peda l when the vehicle is stationary.
Otherwise the vehicle wi ll start to move
immediate ly, even if the parking brake is
set. Th is could result in a crash.
- Do not press the accelerator pedal when
changing the se lector lever position
while the veh icle is stationary and the
engine is running.
- Never engage the R or P selector level positions while dr iv ing. It could cause a
crash .
- Before driving down a steep slope, re­
duce your speed and shift into a lower
gear with "tiptronic" .
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill . Constant braking causes the
brakes to overheat and substantially re­
duces braking pe rformance, increases
b rak ing distan ce or causes complete fa il­
ure of the brake system.
- I f you must stop on an in cl ine, always
hold the vehicle i n place with the foot
brake or park ing brake to p revent it from
rolling back .
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto ­

Hill descent control
App lies to vehicles : wi th 5 tronic tra nsmi ssio n
Hill descent control assists the driver when
driving down hills .
Hill descent control is activated when these­
l ector lever is in the D or S position and you
press the brake peda l. The transmission auto ­
matically selects a gear that is suitable for the
i ncl ine. Hill descent cont ro l t ries to ma inta in
t h e speed ac hieved a t the t ime of b raking,
within physic al and tec hnical lim it a tions. If
may sti ll be ne cessa ry to adju st the speed
with t he b rakes . Because hi ll descent control
cannot sh ift down farthe r than 3rd gear, it
may be necessary to sh ift into t iptronic mode
in very steep areas. In this case, shift into 1st
o r 2nd gear in tiptro nic mode to use the en­
gine's brak ing force to relieve the brakes .
Hill descent control switches off once the hi ll
levels out or you press the accelerator pedal.
On vehicles with a cruise contro l system*
Q page 83, hill descent control is also activat ­
ed when the speed is set .
A WARNING
-
Hill descent control cannot overcome
physical lim itations, so it may not be ab le
to maintain a co nsta nt speed unde r all
conditions . A lways be ready to apply the
b rakes .

202 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, always fo llow the operating
