Lights and Vision
The coming home and leaving home functions
only operate when it is dark and the light switch
is in the AUTO position ¢
page 50, fig. 54.
Auto headlights*
When the light switch is in the AUTO¢ page 50
position, the switch-on point of the lights can be
changed in the automatic driving light function.
Daytime running lights
USA models:
You can switch the daytime running
lights
on and off.
Canada models:
The function cannot be turned
off. It is activated automatically each time the ig­
nition is switched on.
Travel mode*
The headlight beam is asymmetrical. This pro­
vides stronger illumination on the side of the
road on which you are driving. If you are driving
in a country that drives on the opposite side of
the road from your own country, this will cause
glare for oncoming drivers. To prevent glare:
- Travel mode must be selected in vehicles with
Xenon headlights* .
- In vehicles with halogen headlights, certain
areas of the headlight lenses must be covered
with waterproof adhesive covers that prevent light from passing through. For more informa ­
tion, please see your authorized Audi dealer or authorized repair facility.
When travel mode is activated, a display in
the driver information system indicates this
each time you switch the ignition on.

The emergency flashers makes other motorists
aware that you or your vehicle are in an emergen­
cy situation .
.. Press the switch ~¢
fig. 56 to t urn the emer-
gency flashers on or off.
When the emergency flashers are on, all four
turn signals blink at the same time. The turn sig­
nal indicator lights
RB in the instrument clus­
ter, as well as the light in the emergency flasher
switch
IA] blink likewise .
You can indicate a lane change or a turn when the
emergency flashers are switched on by using the
turn signal lever . The emergency flashers stop
temporarily .
The emergency flashers also work when the igni­
tion is turned off.
The emergency flashers will turn on automatical­
ly if you are in an accident where the airbag has
deployed.
@ Tips
You should turn on the emergency flashers
when:
-you are the last vehicle standing in a traffic
jam so that any other vehicles coming can see you, or when
- your vehicle has broken down or you are in
an emergency situation, or when
-your vehicle is being towed by a tow truck or
if you are towing another vehicle behind
you.

Side assist helps you monitor your blind spot and
traffic behind your veh icle . With in the limits of
the system, it wa rns you about vehicles that are
coming closer or that are traveling w ith you with­
i n sensor range
(D c::, fig. 114 : if a lane change is
classified as crit ical , the disp lay @ in the exter io r
mirror ¢
fig. 115 turns on.
The display i n the left exterior mirror provides as­
sistance when making a lane cha nge to the left,
while the d isp lay in the right exterio r mir ror pro­
vides assistance whe n mak ing a lane change to
the r ight .
Information stag e
As long as you do not activate the turn signal,
side assist
informs you about ve hicl es that a re
detected and class ified as crit ica l. The display in
the respective mirror tu rns on, but is dim.
Aud i side assist
The display remains d im intentionally in the in­
formation stage so that your view toward the
front is not d isturbed .

Fig. 117 Rear of the ve hicle: pos itio n of t he sensors
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away. The faste r a vehicle approaches,
the soo ner t he d isplay in the exter io r mirro r will
turn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
100
are indicated by the time they enter your "blind
spot", at the latest.
© Vehicles left behind
If you slowly pass a veh icle that side assist has
detected (the difference in speed between the ve­
hicle and your vehicle is less than 9 mph (1 S km/
h)), the display in the exterior mirror turns on as
soon as the vehicle enters your blind spot.
T he display will not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph (15 km/h)).
Functional limitations
The radar senso rs are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In certain situations , the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area that
i s cr itical for a lane change. For example:
- if the lanes are narrow or if your are dr iving on
the edge of your lane. If thi s is the case, the
system may have detected the vehicle in anoth­
er lane that is
not adjacent to your current lane.
- if yo u are driving through a c urve . Side assist
may react to a vehicle that is one lane over from
the adjacent lane.
- if side assist reacts to other objects (such as
high or disp laced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cover the radar senso rs
q fig. 117 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . Do not
use side assist when towing a trailer. For infor ­
mation on cleaning, refer to
q page 184.
A WARNING
- Always pay attention to traffic and to the
area around your veh icle. S ide ass ist cannot
replace a dr iver's attention. The driver alone
is always responsible for lane changes and
sim ila r driv ing maneuvers.

Audi side assist
(D Tips
-Side assist is not active while you are mak­
ing the adjustment.
- Your settings are automatically stored and
assigned to the remote control key being
used.
Driver messages
Applies to veh icles: w ith Aud i side ass ist

The radar sensors' vision is affected. Do not cover
the area in front of the sensors with bike wheels,
stickers, dirt or other objects. Clean the area in
front of the sensors, if necessary ¢
page 100,
fig. 117.
Audi side assist: Currently unavailable
Side assist cannot be switched on temporarily be­
cause there is a malfunction (for example, the
battery charge level may be too low).
Audi side assist: System fault!

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id­
d ing and loss of veh icle control.
It works only
when the engine is runn ing . ESC detects certain
d ifficult driving situations, including when the ve­
h icle is beginn ing to sp in (yaw) out of control and
he lps you to ge t the vehicle back u nder cont rol by
selectively braking the wheels, and/or reducing
engine power and providing steering assistance
to help hold the vehicle on the driver's intended
course. The indicator light
liJ in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
d itions you may come up against. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. Whe n
there is a section of d ry road that is s uddenly cov ­
ered wi th wa ter, s lush or snow, ESC cannot per­
form the same way it wou ld on the d ry surface . If
the vehicle hydroplanes (rides on a cushion of wa ­
ter instead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, particula rly on w inding roads, ESC
cannot a lways deal as effect ively with d iff icu lt
d riving situat ions than at lower speeds. When
towing a trailer, ESC is not able to he lp yo u regain
con trol as it wou ld if yo u were not towing a trail­
er .
A lways adjust you r speed and dr iving style to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limi ts, increase the
170
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention .
Instead, ESC improves the possibility of keeping
the ve hicle under control and on the road dur ing
extreme maneuvers by using the dr iver's steering
i nputs to help keep the vehicle going in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not expe ri­
ence the benefi ts of ESC.
ESC is switched o n all the time. In ce rtain s itua­
tions when you need less traction, you can switch
off ASR by p ress ing the button [!]¢
page 171,
fig. 164 or ¢page 171, fig. 165. Be s ure to
swi tch ASR on again when you no longe r need
l ess traction .
The following system s are integrated in the ESC:
Anti- lock braking s ystem (ABS )
ABS prevents the wheels from locki ng up when
braking. The vehicle ca n still be steered even dur­
i ng hard braki ng . Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pu lsing in
t h e b ra ke peda l ind icates that the system is he lp­
i ng yo u to b ra ke the vehicle.
Brake assist system
The brake ass ist system can decrease brak ing dis ­
ta nce. It increases braking power when the d river
presses the bra ke peda l quickly in emergency sit­
u at ions. You must press and hold t he b ra ke peda l
u nt il t he s ituation is ove r. In vehicles with adap­
tive cru ise contro l*, the bra ke assist system is
more sensitive if the distance detected to the ve ­
hicle ahead is too sma ll.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the d rive wheels
begin to spi n and adap ts the force to the ro ad
cond it ions . This makes it eas ie r to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL bra kes whee ls that a re spinn ing and
t ransfers the dr ive power to the othe r drive wheel
o r whee ls if the ve hicle is equippe d wi th a ll-wheel
drive*. T his function is not available at higher
speeds .

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 durability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it also calls for more concentrat ion from
the driver .
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 weight. The hitch must be suitable
for your vehicle and trailer 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 in terfere with 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
Alw ays use s afety ch ains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your author ized Audi deal er for cor­
r e ct w iring, sw itches, and relays.
Mirrors
If you are 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
- I f a trai ler has elec trical brake s please note
th at these b ra kes are not acti va ted by the
factory -fitted contro l unit -ris k of acci dent!
- After removing the t railer hi tch, do n ot store
it in your vehicle . In case o f su dden braking,
the hi tch could fly forward and injure you or
your passe ngers.
Operating instructions
Maximum traile r weight
A trai ler for you r vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
B e sure the load in the t ra iler i s held secure ly in
pla ce to prevent it from sh ifting forw ard , back ­
war d or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving in struc tion s on page 182.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's pe rform­
ance is up to the additional load . Ma ke s ure that
t h e coo ling system has enoug h fluid.
