Automatic transmission
-If the engine must run while you are work­
ing in the engine compartment with the
hood open, make sure a gear is not engag­
ed . The selector lever must be firmly in the
P position and locked in place and the park­
ing brake must be set ¢
page 198. Other­
wise, the vehicle could begin moving when
the engine speed is high, even with the
parking brake set.
0 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 automatic trans­
mission to overheat and can damage it. Ac­
tivate the parking brake or press the brake
pedal to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in the N
position will damage the automatic trans­
mission because it is not lubricated under
those circumstances.
- 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
5] or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool¢
page 88.
-Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans­
mission because it is not lubricated

(D Tips
For safety reasons, the parking brake only re­
leases automatically when the driver's door is
closed.
Hill descent control
Applies to veh icles: w ith S tron ic transm ission
The hill descent control system assists the driv­
ing when driving down declines.
Hill descent control is activated when the selec­
tor lever is in the Dor S position and you press
86
the brake pedal. The transmission automatically
selects a gear that is suitable for the incline. Hill
descent 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 brakes. Because hill de­
scent control cannot shift down farther than 3rd
gear, it may be necessary to shift into tiptronic
mode in very steep areas . In this case, shift into
1st or 2nd gear in tiptronic mode to use the en­
gine's braking force to relieve the brakes.
Hill descent control switches off once the decline
levels out or you press the accelerator pedal.
On vehicles with a cruise control system*
¢
page 94, hill descent control is also activated
when the speed is set .
&_ 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.

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect d urability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it a lso calls for more concentrat ion from
the dr iver .
F or this reason, a lways fo llow the operating and
d riving instructions provided and use common
sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suitable
for your vehicle and trai ler and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not i nterfere wit h the impact -absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind~,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system .
Safety chains
Always use s afe ty chains be tween your ve hicle
and the tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your Aud i dea le r fo r corr ect w irin g,
swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
Afte r removing the trailer hit ch, d o no t store
i t in yo ur vehicle. In ca se of sudden br akin g,
the hitch could fly fo rward and inju re you or
your passengers.
Operating instructions
Maximum traile r weight
A trai le r fo r you r vehicle is limited to a typi cal
class 1 or class 2 trai le r.
Trailer load distribution
B e sure the load in the t raile r is held secure ly in
pla ce to p revent it from shift ing forward, back­
ward or sideways .
Never allow a pas senger to ride in a trailer~.&.
in Driving instructions on page 92.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important tha t the cooling system 's pe rform­
ance is up to the additional load. Make s ure that
the coo ling system has enoug h flu id.
Tire pressure
When towing a trailer, inflate the tires of your ve-
hicle to the cold tire pressure listed under "Full

Trailer mode
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
Check to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure tra iler safety cha ins are properly connect­
ed from the trailer to the hitch on the vehicle.
L eave enough slack 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
driving .
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 a trailer always requires extra care
and consideration .
To obta in the best poss ible handling of vehicle
and trailer, please note the following:
.,. Do not tow a loaded tra iler when your car itself
is not loaded.
.. Be especia lly careful when passing other
vehicles.
.. Observe speed limits .
.. Do not drive at the maximum permissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
in a high ly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trailer as light as poss ible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
92
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more diff icult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
conditions are unfavorab le -particularly when
going downh ill.
Reduce veh icle speed
immediately if the trailer
shows the slightest sign of swaying .
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ile rs are lower than fo r regular
vehicles .
Always apply brakes early. When driving down­
hill, shift int o a lo wer gear to use the eng ine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge¢ page 12 must
be obse rved carefully. The coolant temperature
can increase if you dr ive on long inclines in a low
gear at high engine speeds . Reduce your speed
immediately if the LEDs in the top part of the dis­
play turn on .
For more information abo ut ind icator lights, re­
fer to. ¢
page 19 .
A WARNING
-
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not proper ly wearing the restraints provided
by Aud i.
Trailer mode notes
Important to know
Your vehicle handles differently when towing a
trai ler because of the additiona l weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how careful-
ly you load your trailer and operate your r ig. ..,.

Assist
Assist Electronic speed limiter*
Applies to veh icles: with electronic speed limiter
Your vehicle may be factory equipped with ti res
that are rated for a maximum speed of 130 mph
(210 km/h) . T his is less than the maximum speed
of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
limiter prevents your vehicle from going faster
than the tir e speed rat ing . For more information
~page 221.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢4 will illuminate . If this occurs,
contact the nearest a utho rized Audi dealer for as­
sistance .
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions . Never drive your
vehicle faster than the maximum speed rating of the tires installed.
Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed.
-
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
You will hear a warning tone when your speed ex­
ceeds the stored value by approximately 3 mph
(3 km/h) . Th e. (USA models)/. (Canada
models) indicator light and the message
Speed
limit exceeded!
appear in the instrument cluster
disp lay at the same time . The ./. indicator
light turns off when the speed decreases below
the stored maximum speed.
Setting a thresho ld is recommended if you would
like to be reminded when you re ach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
94
al speed limit or if there is a specified maximum
speed for winter tires.
(D Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit .
Setting the threshold
You can set, change and delete the threshold in
the MMI.
.. Select: the I MENU I button >Car> Systems*
contro l button > Driver assistance > Speed
warning.
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
· Description
Applies to vehicles: with cruise control system
The cruise control system makes it poss ible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modify ing engine
power or through an act ive brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation.
You are a lways responsible for your speed
and the distance between your vehicle and
other vehicles.
- For reasons of safety, cruise contro l should
not be used in the city, in stop-and-go traf­
fic, on winding roads and when road condi­ tions are poor (such as ice, fog, gravel,
heavy rain and hydroplaning) -you could
have an accident .
- Switch the cruise control off temporarily
when driv ing in turning lanes, highway exits
or in construction zones .

Applies to vehicles : with Audi active lane assist
Active lane ass ist detects lane marker lines with­
in the limits of the system using a came ra in the
windshie ld. If you are app roach ing a detected
lane marker line and it appears like ly that you
will leave the lane, the system will warn you with
corrective steering . You can override this steering
at any time. If you pass over a line, the steering
wheel will v ibrate light ly. In order for this warn­
ing vibrat ion to occur, it must first be switched
on in the MMI. Active lane assist is operable
when the lane marker line is detected on at least one side of the veh icle.
l) T hi s function is not ava ilable in all cou ntri es.

The system will not warn you befo re crossing a
l ane marker line if you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
The system is des igned for driving on express ­
ways and highways and therefore on ly activates
at speeds above approx imately 40 mph (65 km/
h).
A WARNING
-
- The system warns the driver that the vehicle
is leaving the lane using corrective steering .
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself.
Al­
ways keep you r hands on the steering
wheel.
- Corrective steer ing may not occur in certa in
situa tions, su ch as during heavy braking.
- There may be cases where the camera does
not recognize all lane ma rker lines. Correc­
tive stee ring can only take p lace on the side
of the vehicle where lane marker line5 are
detec ted.
- Othe r road structures or obje cts cou ld possi­
b ly be identified un intent ionally as lane
marker l ines . As a result, corrective steering
may be unexpected or may not occur .
- The camera view can be restricted, for ex ­
ample by vehicles driving ahead or by rain,
snow, heavy spray light shining into the
camera or by d irt on the window. This can
result in active lane ass ist not detecting the
lane marker lines or detecting them incor­
rectly.
- In certain situat ions where visibility is low,
the vehicle may switch from "early" to "late"
corrective steering
l l.
- Under certain co nditions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steering a lone may not be enough
to keep the vehicle in the midd le of the lane.
