22 Instruments and warning/indicator lights
@.D Light/rain sensor
II Automatic headlights/automatic wipers:
system fault
If the indicator light turns on and this mes­
sage appears, the light/rain sensor is not
functioning correctly.
For safety reasons the low beams are turned
on permanently with the switch in AUTO .
However, you can continue to turn the lights
on and off using the light switch. You can still
control all functions that are independent of
the rain sensor through the windshield wiper
lever.
Contact your authorized Audi dealer as soon
as possible to have the problem corrected.
@! Dynamic steering
'T-ij Steering: system fault. you can continue
driving
If the indicator light turns on and the mes­
sage appears, the steering may be more diffi­
cult to move or more sensitive than usual. The
steering wheel may also be at an angle when
driving straight.
Drive slowly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected.
(;y.ij Dynamic steering: initializing
If this driver message appears and the indica ­
tor light is flashing on the instrument panel,
dynamic steering is being reinitialized . Once
you start the engine after this is finished, the
steering wheel will be easy to move . Re-initi­
alization might be necessary if the steering
wheel was moved hard to the left and right
while the vehicle was not moving. The display
goes out as soon as initialization is complete.
A WARNING
-
Have the dynamic steering system mal­
function repaired as soon as possible by an
authorized Audi dealer or any qualified
workshop -risk of accident!
(D Tips
- The dynamic steering stability systems
are not available in the event of a system
malfunction.
- For additional information on dynamic
steering, refer to¢
page 109.
~= Sport differential
I'll Sport differential: system fault
There is a malfunction with the sport differen­
tial.
Drive to your authorized Audi dealer immedi­
ately to have the malfunction corrected.
I'll Sport differential: overheating
The transmission temperature has increased
significantly due to the sporty driving manner. Drive in a less sporty manner until the tem­
perature returns to the normal range and the
indicator light switches of.
.&_ WARNING
Contact your authorized Audi dealer or a
qualified workshop if the sport differential
is faulty or malfunctioning. The repair
must be performed by trained personnel
using the correct oil in order to ensure
safety.
¢i ¢ Turn signals
-
The indicator light blinks when you use either
turn signal.
Whenever you use the left Hor the right II
turn signal, the indicator light blinks. When
you use the emergency flashers, both indica­
tor lights flash .
If one of the turn signal light bulbs burn out,
the turn signal will blink twice as fast as nor­ mal. Carefully drive to your authori zed Audi
dealer immediately to have the malfunction
corrected. The indicator light does not indi­
cate a malfunction if a turn signal on the trail ­
er or on the vehicle fails in trailer towing
mode. ..,

When stopping at a traffic signal or stopp ing
i n city traffic, the parking brake can be ap­
p lied . The vehicle does not have to be held
with the footbrake. The park ing brake elimi­
nates the tendency to creep with a drive range
engaged. As soon as you dr ive off as usual,
the park ing brake is released automatically
and the vehicle starts to move .
Starting on slopes
When starting on inclines, the start ing ass ist
prevents the vehicle from unintentionally roll­
i ng back. The braking force of the parking
brake is not released until sufficient dr iv ing
force has been bu ilt up at the whee ls.
O') Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er's safety belt is engaged in the buck le.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch(®) pulled and depress the
acce lerator. The park ing brake stays applied
and prevents the vehicle from rolling back­
ward .
.. You can release t he sw itch C®l once you are
s u re that yo u are develop ing eno ugh f or­
wa rd momentum at the wheels as you de­
press the accelerator.
D epending on the weight of the r ig (veh icle
and trai le r) and the severi ty of the in cli ne, you
may roll backwards as you sta rt. Yo u can pre ­
ve nt roll ing backwards by holding the parking
brake switch C®) p ulled out and acce lerating -
just as you would when starting on a hill with
a conventional hand brake.
On th e ro ad 87
Emergency braking
In the event that the conventional brake sys­
tem fails or locks .
.. In an emergency, pull the sw itch(®) and
cont inue to pull it to s low your ve hicle down
w ith the park ing brake.
.. As soon as you release the switch C®> or ac-
celerate, the b ra ki ng process stops.
If you pu ll the switch C®> and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy brak ing f unction is initia ted . T he ve hicle is
braked at all fou r whee ls by activating the hy­
d raulic brake sys tem. The brake pe rform ance
is simila r to making an emergency stop~ .&..
In order not to act ivate the emergency brak­
ing by mis take, an audib le wa rn ing tone (buz­
z er) so unds whe n the switch(®) is pulled . As
soon as the sw itch<®> is re leased, or the accel­
erator peda l is depressed, emergency braking
stops.
_& WARNING
Emergency braking should only be used in
an emergency, when the normal foot bra ke
has fa iled or the brake pedal is obstructed.
Using the parking brake to pe rform emer­
gency b rak ing will slow your vehicle down
as if you had made a full bra ke application .
T he laws of physics cannot be su spended
even wi th ESC and i ts asso ciated compo­
nents (ABS, ASR , ED L) . In corners and
when road or weather con ditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.

Side assis t fu nctions at speeds above ap prox i­
ma tely 19 mph (30 km/h).
(D V ehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change
even if it is still
somewhat far away. The fas ter a vehicle ap­
p ro aches, the sooner the disp lay in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr it ical
for a lane change. All vehicles detec ted by
side assis t are in dicated by the time they en­
ter your "blind spot", at the latest.
@ Vehicles left behind
If you s low ly pass a ve hicl e tha t sid e ass ist has
dete cted ( the difference in s peed between the
vehicle and you r vehicle is less than 9 mph or
15 km/ h), the display in the exterio r mirror
turns on as soon as the vehicle enters your blind spot.
The display wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (t he d if ­
f erence in speed between the ve hicle and your
vehicle is greater than 9 mph or 15 km/h).
Functional limitations
T he radar senso rs are designed to detect the
left and right adjacent lanes when the road
l anes a re the normal width. In certain situa­
t ions, the d isp lay in the exterior mirror may
turn on even though there is no ve hicle locat­
ed in the area that is cr itical fo r a la ne cha nge.
Fo r example:
- if the lanes are narrow or if your are driving on the edge of your lane. If this is the case ,
the system may have detected the vehicle in
another lane that is
not adjacent to you r
cur rent lane .
- if you a re driving through a c urve . Side assis t
may react to a vehicle that is one lane ove r
from the adjacent lane .
- if side assist reacts to other objects (such as
high or d isp laced gua rd rails) .
- In poor weather conditions. The side assist
fu nctions are limited .
Do not cover the radar sensors
c::> fig. 111 with
stickers, depos its, bicycle wheels or other ob­
jects, because this wi ll affect the funct io n. Do
not use s ide ass ist when towing a trailer . For

lected mode and ranges from subtle to sporty .
Q) Note
-Make sure there is enough clearance
above and below the vehicle when park­
ing. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load cond i­
tions and changes to the dr iv ing modes,
which can affect clearance .
- When transporting the vehicle on a car
carr ier, tra in, ship or by other means, on­
l y tie the veh icle down at the running
surface of the tires, which is the outer
ci rcumfe rence . Securing the vehicle at
the axle components, s uspension str uts
or towing eyes is not pe rmitted because
the press ure in the air suspension s truts
can change during transport. The vehicle
may not be sec ured s ufficient ly if this
happens.
- If you are going to tow a trailer, you must activate the trailer ope ration mode
