Lights and V ision
Audi adaptive light
Appl ies to: veh icles w ith Audi adaptive light
Adaptive light provides bette r visibili ty when i t is
dark by adapting the ligh ts to the road condi tions
based on speed, such as on e xpressways, rura l
roads, at intersections, and in curves. The adap­
t ive lights only function when the light switch is
in the AUTO* posit ion and the all weather lights
are switched off .
A WARNING
-
- Automatic headlights * are on ly intended to
assis t the dr iver. They do not relieve t he
d river of respons ibi lity to check the head­
lights and to turn them on manua lly based
on the cur re nt ligh t and v isibility condition s.
For e xamp le, fog cannot be detected by the
light senso rs . So always switch on the low
beams under these weather con dit ions an d
when dr iv ing in the dark
fD.
- The rear fog lights sho uld only be turned on
in accordance wit h traffic regulations , to
prevent glare for traffic behind your vehicle.
- If the ve hicle battery has bee n discharging
for a wh ile, the park ing light may switch
off
automatically. A lways make su re your vehi­
cle is parked and adequate ly lit acco rdi ng to
the laws . Avo id us ing the parking ligh ts for
seve ral hou rs .
- Always observe legal regulations when us­
i n g the lighting systems described.
@ Tips
- The lig ht sensor for the automat ic head­
lights* is in the rearview mirror mount. Do
not p lace any st ickers in this area on t he
w indshield .
- Only the front headlights turn on when the
daytime running lig hts are sw itched on *. In
veh icles in ce rtain markets, the tai l lights
w ill also tu rn on.
- In cool or damp weathe r, the inside of the
head lights, t urn sign als and tail lights can
fog ove r due to t he tempera ture diffe rence
b etween the ins ide an d ou tside. They wi ll
clear shortly a fter swi tching them on. This
does not affect the service life of the light­
ing .

next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (fuel shut-off during decelera­
tion).
Shift efficiently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fuel unnecessari­
ly .
Press down on the accelerator pedal slowly and
avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles without the Start/
Stop system, it is efficient to switch the engine
off when stopped
at railroad crossings and long
red lights. Depending on the version of the en­
gine, stopping the engine for as little as five sec­
onds once it has reached operating temperature
still saves more fuel than leaving the engine run­ ning
-even when taking into account the amount
of extra fuel that is used to restart the engine.
It takes a very long time in idle to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this.
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al­
so impacts
fuel consumption. A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Driving
Avoid short trips
The engine and emissions control system must
reach their optimal
operating temperature to ef­
fectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fuel. The engine reaches operating
temperature and consumption normalizes only
after approximately 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct pressure
r=;, page 33 5. The
fuel consumption can increase by S% if the pres­
sure is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures will also
lead to greater tire
wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62-75 mph
(100-120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
(D Note
- Do not leave engine idling unattended after
starting. If warning lights should come on
to indicate improper operation, they would go unheeded. Extended idling also produces
heat, which could result in overheating or

speed and the distance between your
vehicle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road condit ions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because th is increases the
r isk of an accident.
- Switch the cruise control off temporar ily
when driving in turn ing lanes, h ighway exits
or in construction zones.
- Please note that unconsciously "resting" yo ur foot on the accelerator pedal prevents
the cruise control from braking. This is be­
ca use p ressing the acce le rato r pedal ove r­
rides the c ruise contro l system.
- If a bra ke system ma lf u nction such as over­
heating occu rs when the c ruise contro l sys­
tem is sw itched on, the braking function in
the system may be switched off . The rest of
the cr uise control system f unctions remain

Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. Th is makes use of the eng ine

corrective steering shortly before you leave the lane . This will attempt to keep your vehicle in the
lane .
Appl ies to: veh icles without Audi sid e assist
The system will not warn you before crossing a
lane marker line if you have activated the turn
signal. In this case , it ass umes that you are
changing lanes intent ionally.
& WARNING
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsib le 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 your hands on the steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy brak ing.
- There may be cases where the camera does not recogni ze all lane marker lines. Correc­
t ive steering can only take p lace on the side
of the veh icle where lane marker lines are
detected.
- Other road structures or objects could possi­
bly be identified unintentionally as lane
marker lines . As a result , corrective steering
may be unexpected or may not occur.
- The camera view can be restr icted, for ex­
amp le by vehicles driv ing 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 l ines or detecting them incor­
rectly .
- Under certain conditions such as ruts in the road, an inclined roadway or crosswinds, the
corrective steering alone may not be enough
to keep the vehicle in the middle of the lane.
- For safety reasons, active lane assist m ust
not be used when there are poor road and/
or weather conditions such as slippery
roads, fog, gravel, heavy ra in, snow and the
potent ial for hydroplaning . Using active lane
assist unde r these conditions may increase
the risk of a crash.

Ass is tance sy stems
If the system is switched on but is not ready to
provide warn ings, one of the following cou ld be
the cause:
- T here is no lane marker line .
- The re levant lane marker lines are not detected
(for example, markings in a constru ction zone
or because they are obstructed by snow , dirt,
water or lighting).
- T he vehicle speed is below the ac tiva tion speed
of approx imately 40 mph (65 km/h).
- T he lane is too narrow or too wide .
- T he curve is too nar row .
- The driver's hands are not on the steering
whee l.
@ Tips
-Make sure the camera 's field of view
