Selector lever positions
Fig. 82 Instrument cluste r: se lecto r leve r po sition s
The selector lever position that is engaged is
shown in the instrument cluster display .
P- Park
T his selector l ev er position prevents the vehicle
from rolling. You can only sh ift into Park when
the vehicle is
stationary ¢.&. .
To shift in and out of the P selector lever posi­
tion, press the interlock button in the selector
lever
while pressing the brake pedal. This only
works when the ignition is turned on.

Only shift into reverse gea r when the vehicle is
stationary and the engine is running at idle
speed ¢.&. .
To select the R se lector lever position, press t he
interlock button
while pressing the brake peda l
at the same time. The back-up lights switch on in
the R position if the ignition is switched on .
N -Neutral
The transm iss ion is in idle in this pos it ion ¢,&. .
DIS -Normal pos iti on for d riv ing forward
In the D/S selector lever pos ition, the transm is ­
sion can be ope rated either in the normal D mode
or in the S sport mode . T o select the S sport
D rivi ng
mode, pull the selector lever back briefly. Pulling
the lever back again will select the normal D
mode. The instrument cluster d isp lay shows the
selected driving mode.
In the
n o rmal mode "D", the transmission auto ­
matically selects the suitable gear ratio .
It de­
pends on engine load, vehicle speed and driving
style.
Se lect the
sport mode "S " for sporty driving. The
vehicle makes fu ll use of the engine's power.
Sh ift ing is more not iceable when accelerating .
To move from selecto r lever pos ition N to D, you
must press the brake pedal and the vehicle must
be traveling less than 1 mph (2 km/h) or be sta­
t ionary ¢.&. .
A WARNING
----
-The vehicle can roll even if the ignition is
sw itched off.
- Never se lect R or P while driving, because
this increases the risk of an accident.
- Power is still transmitted to the wheels
when the engine is running at idle . To pre­
vent the vehicle from "creeping", you must keep your foot on the b rake in all selector
lever positions (except P) when the engine is
r u nning. Otherwise, this inc reases the risk
of an acc ident.
- Do not inadvertently p ress the accelerator
pedal when the vehicle is stopped if a gea r is
engaged. O therwise the ve hicle will start to
move immed iate ly, even if the parking brake
is set . This could result in a crash.
- To decrease the r is k of an accident, these­
lecto r lever mus t be in the P pos ition and
the parking brake must be set before open ­
ing the hood and working on a running en­
g ine. A lways read and follow the applicable

Hill descent control
The hill descent control system assists the driver
when driving down hills .
Hill descent control is act ivated when the selec­
tor leve r is in the D or S position and yo u press
the brake peda l. The transmission a utomatica lly
selects a gear that is suitable for the hi ll. Hill de ­
scent control tries to maintain the speed ach ­
ieved at the time of braking, w ith in physical and
technical lim itations . If may still be necessary to
adjust the speed w ith the brake pedal.
Hi ll descent control switches off once the hill lev-
els out or you press the accelerator pedal.

Driving
On vehicles with a cruise control system*
¢ page 84, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all condit ions. Always
be ready to apply the brakes.
Shifting manually (tiptronic mode)
The tiptronic mode allows the driver to shift the
gears manually.

" N .... 0 0 \.J - Trailer towing Driving with a trailer
General information
Your veh icle is primar ily intended for transport­
ing people and luggage. However, if you dr ive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg­
u lations.
Driving with a trailer affects the vehicle 's fuel
consumption, performance and wear. It also re­
quires highe r concentration from the driver.
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
hitch mount and ball hitch. The trailer hitch must
be perm itted for the vehicle, the trailer and the
permitted total weight of the trailer being
pu lled. Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If the tra iler has its own brake system, then fol­
l ow the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Trailer towing
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The coo ling sys­
tem must be designed for additiona l load and
contain enough coo lant
i::> @ .
@ Note
Longer inclines cannot be driven without a
suitab le cooling system, especia lly if t he out­
side temperatures are high . otherwise, this
increases the risk of engine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribut ion can negatively
impact vehicle handling.
- Store objects preferably in the vehicle luggage
compartment . The vehicle should always carry
the heaviest poss ible load and the trailer
should have the lightest possible load.
- Distribute the load in the trailer so that the
heavy objects are as close to the axle as poss i­
b le.
- Secure objects from sl iding out of place .
- Ut ilize the maximum permitted tongue weight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure sticker
c::>page 211.
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom­ mendat ion .
Winter tires should be mounted on the vehicle and on the trailer during winter temperatures.
Outside mirrors
If you cannot see the tra ffic behind the trailer
with the standard exterior mirrors, then you

Speed warning system
Description
Applies to: veh icles with speed warning system
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.
A warning tone will sound as soon as your speed
exceeds the sto red value slightly.
The . (USA models) I. (Canada models) indi­
cator light and a message appear in the instru­
ment cluster display at the same time.
The.
• indicator light and the message turn off if the
speed falls back below the stored maximum
speed.
Sett ing a threshold is recommended if you would
like to be reminded when you reach a certa in
maximum speed. S ituations where you may want
to do so i nclude driving in a country wit h a ge ne r­
a l speed limit o r if the re is a specified maximum
speed for winter tires.

cle and other vehicles.
-For safety reasons, cruise control should not
be used in the city, in stop-and-go traff ic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy rai n and
hyd roplaning), because this inc reases the
r is k of an accident.

a co .... N
" N .... 0 0 \,;J ' -With stationary objects ¢ page 88.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active . As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision. The
driver is always responsible for braking at the
correct time.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing). Using the system under these condi­
tions increases the risk of an accident.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the stored speed when in these situations .
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani­
mals, objects crossing the road or oncoming
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
A WARNING
- Improper use of adaptive cruise control can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adaptive cruise control and braking guard
Assistance systems
offer distract you from the need to be alert
to traffic conditions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain
the set distance when you drive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped
in a traffic jam, a stalled or disabled vehicle.
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warning and if confirmed by the
video camera, an acute collision warning.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The adap­
tive cruise control cannot slow or brake the
vehicle safely when you follow another vehi­ cle too closely. Always remember that the
automatic braking function cannot bring the
vehicle to a sudden or emergency stop un­
der these conditions .
- To prevent unintended operation, always
switch ACC off when it is not being used .
@ Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and underbody . That could affect the adaptive
cruise control system and braking guard .
Have an authorized Audi dealer or authorized
Audi Service Facility check their function.
