u. 00 .-< N l'­ N .-< 0 N > 00
-Power is still transferred to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must keep your foot on the brake when the en­
gine is running and the selector lever is in
the "D", "S" or "R" position or "tiptronic"
mode is selected.
- Do not inadvertently press the accelerator
peda l when the vehicle is stopped if a gear is
engaged. Otherwise the risk of an accident
increases because the vehicle will start to
move immediately, even if the parking brake
is set.
- To reduce the risk of an accident, do not
press the acce lerator pedal when changing
the selector lever position while the vehicle is stationary and the engine is running.
- Never engage the "R" or "P" selector leve l
positions while driving. It could cause a
crash.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"ti ptron i c".
- 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 performance, increases brak­
ing distance or causes complete failure of
the brake system.
- If you must stop on an incline, always hold
the vehicle in p lace with the foot brake or
park ing brake to prevent it from rolling
back.
- Never hold the veh icle on an incline with a
sl ip ping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. The
ml indicator light turns on
and a message appears
¢ page 89 when
the clutch is over loaded .
{LlJ) Note
- When stopping on an incline, do not try to
ho ld the vehicle in place by pressing the ac­
ce lerator pedal while a driving gear is se ­
l ected. This can cause the automatic trans ­
mission to overheat and can damage it. Set
Driving
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped while the selector lever is in the
"N" position will damage the automatic
transmission, because it is not lubricated
under those circumstances
¢ page 3 78,
Towing with a tow truck.
- The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions such as frequent starts, creeping for a
long time, or stop-and-go traffic. When the
ml or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool¢
page 89.
(D Tips
For safety reasons, the park ing brake only re­
l eases automatically when the driver's door is
closed.
Hill descent control
App lies to : vehicles wi th automatic transmiss ions
The hill descent control system assists the driver
when driving down hills.
Hill descent control is act ivated when the selec­
tor lever is in the "D" or "S" posit ion and you
press the b rake pedal. The transmission auto ­
matically se lects a gear that is suitab le for the
hill. Hill descent contro l tries to ma inta in the
speed achieved at the time of braking, within
physical and technica l limitations. If may still be
necessary to adjust the speed with the brakes.
Because hill descent control cannot shift down
farther than 3rd gear, it may be necessary to
shift into tiptronic mode in very steep areas . In
th is case, shift into 2nd or 1st gear in t iptronic
mode to use the engine's braking force to rel ieve
the brakes.
Hill descent control switches
off once the hill lev­
els out or you press the accelerator pedal.
On vehicles with a cruise control system*
¢ page 120, hill descent control is also activated
when the speed is set .

Speed warning system
Description
Applies to: veh icles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
A warni ng tone will sound as soon as your speed
exceeds the sto red value slight ly. The
[OJ (USA
models) ;[;] (Canada models) indica to r li gh t and
the co rresponding message appear in the inst ru­
ment cluster display at the same time. The
[C]
(USA models)/ [ej (Canada mode ls) indicator
light and the message turn off w hen the vehicle
speed drops below the stored maximum speed .
Sett ing a threshold is recommended if you would
like to be reminded when yo u reach a certa in
maximum speed . Situations where you may want
to do so include driving in a country with a ge ner­
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning thr eshold
.. Select in the Infotainment sys tem : IMENUI but­
ton
> Vehicle > left contro l button > Driver a s­
sistance
> S peed warning > Manual.
@ Tips
Regardless of the speed warning system, you
should always monitor yo ur speed using the
speedometer and make sure you are following
the legal speed limit.

&_ WARNING
- Always pay at ten tion to the traffic a ro und
you whe n the cruise contro l system is in op­
erat ion . You are always respons ible fo r your
speed and the distance between your vehi­
cle and other vehicles.
-For safety reaso ns, cruise cont rol should not
be used in the city, in stop-and-go traff ic, on
w inding roads and when road conditions are
poor (such as ice, fog, gravel, heavy rai n and
hydroplaning), because this increases the
r isk of an accident.
-Switch t he cr uise control off temporarily
when dr iv ing in turning lanes, highway exits
or in construction zones .
- Please note that unconsciously
"rest ing"
your foot on the accelerator pedal prevents
-

u. 00 .-< N l'­ N .-< 0 N > 00
the cruise control from braking. This is be ­
cause p ressing the acce lerato r pedal over ­
rides the cruise contro l system.
- If a brake system ma lf u nction such as over­
heating occurs when the cruise contro l sys­
tem is switched on , the braking function in
the system may be switched off . The rest of
the cr uise control system f unctions remain
act ive as long as
the @;(i)~14 (USA models) /
lll (Can ada models) indicato r light is o n.
@ Note
Before driving downhill a long distance on a
s teep hill, decrease yo ur speed and select a
lower gear. This makes use of the eng ine
b rak ing effect and re lieves the bra kes.

Audi adaptive cruise

Description
Applies to: vehicles with Audi adaptive cruise control
)
F ig . 122 De tect ion range
A ss istance systems
T he adaptive cruise cont rol system is a combina­
tion of speed and distance regu lation.
It assists
the driver by both regu lating the speed and
maintain ing a d istance to the vehicle driv ing
ahead, w ith in the limits of the system. If the sys­
tem detects a vehicle driving ahead, the adaptive cruise control can brake and accelerate your vehi­
cle . T his increases d riving comfort during long
trips o n highways and in stop-and-go traffic.
What can adap tiv e crui se con trol do ?
The adaptive cru ise control sys tem uses radar .
The radar is subject to designated system limits
¢ page 124 .
On open roads with no traffic, it functions like a
cruise contro l system . The stored speed is main­
ta ined . When approaching a vehicle ahead and
the system detects it, the adapt ive cruise control
system automat ically brakes to match that ob­
ject's speed and t hen maintains the stored d is­
t a nce. As soon as t he sys tem does not de tec t a
vehicle driving ahead, adaptive cruise cont ro l ac ­
ce lerates up to the stored speed .
Within the lim its of t he sys tem, adapt ive cru ise
contro l can brake in stop -and-go t raff ic until t he
vehicle is s tat iona ry and then begin driving again
under certain conditions ¢
page 12 7, Driving in
stop-ond-go traffic .
Which functions can be controlled?
When you switc h adap tive cr uise control o n, you
can set the cur rent speed as the "contro l speed"
¢ page 12 5, Switching on/off .
When driving, yo u can stop cru ise cont rol
¢ page 127 or change the speed ¢page 126 at
any t ime .
You can also set the distance to the vehicle ahead and set the adaptive c ruise cont rol d riving pro­
