(D Note
-Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let. lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage .
- Do not alter or
remove any component of
the Emission Control System unless ap­ proved by the manufacturer.
- Do not alter or
remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle components.
{t) Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
Steering
Adjusting the steering wheel position
The steering wheel position is adjustable up and
down and forward and back .
Fig. 76 Lever on the steeri ng col umn
.. Pull the lever in the direction of the arrow
¢,&. .
"'Bring the steering wheel into the desired posi­
tion.
Driving
.. Push the lever against the steering column un­
til it is secure.
A WARNING
Incorrect use of the steering wheel adjust­ ment and an incorrect seating position can
cause serious injuries.
-
- Only adjust the steering column when the
vehicle is stationary so that you do not lose
control of the vehicle.
- Adjust the driver's seat or steering wheel so
that there is at least a 10 in (25 cm) dis­
tance between your chest and the steering
wheel. If you do not maintain this distance
I
you will not be properly protected by the air­
bag system.
- If your physical characteristics prevent you
from sitting at least 10 in (25 cm) or more
away from the steering wheel, see if your
authorized Audi dealer or authorized Audi
Service Facility can provide adapters that
will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision. Always make sure that the steering wheel is level with your
chest.
- Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of injury if the airbag
deploys.
- Never hold the steering wheel in the 12
o'clock position or with both hands on the
rim or the center of the steering wheel.
Holding the steering wheel incorrectly sig­
nificantly increases the risk of injury to the
hands, arms and head if the airbag deploys.

Trailer towing
Trailer towing
Driving with a trailer
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, econo­my and performance.
Trailer towing not on ly places more stress on the
ve hicle, it also ca lls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross tra iler weight. The hitch must be suitab le
for your veh icle and tra iler and must be mounted
securely on the vehicle's chassis at a technically
sound
locat ion . Use on ly a trailer hitch with a re­
movable ba ll mount . Always che ck with the t rail ­
er hitch man ufac tur er to make s ure t hat you are
using the co rrect hi tc h.
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 mod ificat ions should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, che ck that all hitch mo unti ng
bol ts rem ain securely f aste ned.
W hen you are not tow ing a tra iler, remove the
tra ile r hitc h ba ll mount . This prevents the hit ch
from caus ing damage s hou ld your veh icle be
s truck from be hind ¢
,&..
Trailer brakes
If you r trailer is equipped with a brak ing system,
check to be su re that it conforms to all regula­
tions .
90
The t rai ler hydraulic bra ke system must not be
directly connected to the vehicle's hydraulic
bra ke system ¢&. .
Safety chains
Always use s afety chains be tween you r vehi cle
and t he tra ile r.
Trailer lights
Traile r lights must meet all regula tions . B e s ure
to check w ith your author ized Audi dealer for cor­
r ec t wir ing, swi tches and relays.
Mirrors
If you are unable to see t he traffic behind you us­
i ng t he regular outs ide mirrors, then yo u
must in­
stall ex tended mirrors . It is impo rtant that you
al ways have clear vision to the rear.
.&_ WARNING
Afte r remov ing the tra ile r hi tc h, do not s tore
it i n y our vehicle. In case o f su dden brak ing,
the hitch could fly fo rward and injure you or
your passengers.
Operating instructions
Maximum trailer weight
A tra iler f or yo ur vehicle is lim ite d to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the t rai le r i s he ld se curely in
pla ce to p reve nt i t from shi fting forwar d, bac k­
ward or si deways.
Never allow a passenger to ride in a trailer ¢ &.
in Driver messages on page 91.
Engine cooling system
Towi ng a tra iler makes the engine work harder. It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure tha t
the coo ling system has enoug h fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire p ressure listed under "Full
load" on the t ire press ure label. The t ire pressure

increasing force within the limits of the
system
l)_ This reduces the vehicle speed in the
event of a collision. At low vehicle speeds, pre
sense front can initiate a complete deceleration
shortly before a collision with a vehicle driving
ahead
1>. If pre sense front determines that you
are not braking strongly enough when a collision
is imminent, it can increase the braking force .
The following functions trigger in conjunction
with pre sense basic/rear at corresponding vehi ­
cle speeds :
- Reversible tensioning of the front safety belts.
- Closing the windows and sunroof*.
- Inflating the side bolsters* in the seat backrest
and seat surface.
Audi drive select*: the reversible belt tensioner,
the closing of the windows and sunroof* as well
as the inflating of the side bolste rs* on the seat
backrest and seat surface are not active depend­
ing on the mode selected .
Collision avoidance assist
Collision avoidance assist helps you to steer the
vehicle around an obstacle in a critical situation.
If you avoid an obstacle after the acute warning,
then the collision avoidance supports you by ap­ plying slight steering adjustment to correct your
steering wheel angle as long as you are actively
steering. Collision avoidance assist is available at
speeds between approximately 20 mph (30 km/
h) and 90 mph (150 km/h).
Turn assist
When starting to drive and up to speeds of maxi­
mum 6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning left or right (available in certain countries) . The
braking intervention causes your vehicle to stay
in its lane.
.8, WARNING
-Pre sense front cannot overcome the laws of
physics.
It is a system designed to assist and

it cannot prevent a collision in every circum­
stance. The driver must always intervene.
The driver is always responsible for braking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This could increase your risk of a collis ion.
- The system can deploy incorrectly due to
system-specific limits.
- Please note that the sensors and the camera
do not always detect all objects or lane
markings . This increases the risk of an acci­
dent.
- Pre sense front does not react to people, an­
imals or objects that are crossing the vehi­
cle 's path or that are difficult to detect
c> &..
in General information on page 97.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collision risk.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense front can be impaired
by this. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their func­
tion.
(D Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.
- Certain pre sense front functions are switch­
ed off when the ESC is limited or switched
off
