Economical use of the climate control
system
Economical use of the climate control system helps save
fuel.
When the climate control system is working in cooling mode,
engine performance is reduced and fuel consumption is
affected. To keep the time the climate control system is on as
short as possible, you should do the following:
- To save fuel, turn off cooling mode by pressing the AC
button (indicator light goes out).
- In addition, if you open the window while driving, turn off
cooling mode by pressing the AC button (indicator light
goes out).
- If the vehicle is extremely hot due to the heat of the sun,
briefly open doors and windows.
~ For the sake of the environment
When you save fuel, you reduce emissions from the vehicle. •

Automatic recirculation
An air quality sensor detects increased concentrations of pollutants
in the outside air and automatically switches to recirculation mode. We recommend that you always keep automatic
recirculation ON to
prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the climate control system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the factory-installed pollutant filter or whether it is
necessary to switch to recirculation. With heavy concentrations of
pollutants, the climate control system is switched automatically to
recirculation mode and the supply of outside air is blocked. As soon
as the concentration of pollutants in the outside air drops, fresh air is
supplied to the vehicle interior again.
In the event that the windows fog up during automatic recirculation,
press the
l@I button immediately.
Under certain operating conditions, automatic recirculation is
switched off automatically. When outside temperatures are below
about 50
°F ( + 10 °(), automatic recirculation is limited to
30 seconds. When outside temperatures are below about 30
°F (-
1 °C), automatic recirculation is limited to 15 seconds .
Synchronization
After Synchronization is set to on, all of the subsequent climate
control settings (except for seat heating*) for the driver are trans­
ferred to the front passenger .
Synchronization is canceled when settings are adjusted on the front
passenger's side .•

Adaptive cruise control
Speed and distance control system
Applies to veh icl es : w it h adaptive c ruise contro l
Description
The adaptive cruise control driver assistan ce program is a
combined speed and distance control system .
Fig. 113 Front
bum per : Po sitio n of
ra dar sen sor
Any speed betwee n about 20 mph (30 km/h) and about 95 mph
( 1 50 km/ h) can be set and held with the adaptive cruise control. The
system also regu lates a pre-set distance from the vehicle ahead
w ith in the limits of the system described.
Driv ing c an be more relaxed, particularly o n long tr ips on inter states
or on other highways that a re generally straig ht.
How does it work?
Yo u ca n operate the adaptive c ruise contro l using the leve r o n the
steer ing wheel column:::,
page 119, "H ow is the speed sto red? " and
=:> pag e 121, "How is the distance (time interval) set?".
Driver information
Important info rmation is brought up in the speedometer and in the
instrumen t cluster dis play as the ve hicl e is be ing driven :::,
page 122,
"Driver in format ion ".
What is important for you to know
The adaptive cru ise cont rol is set with system-specified lim its, that is,
a s a driver, yo u will h ave to adju st the speed and dist an ce to the
vehicle ahead in some instances :::,
page 126, "Driver inte rvention
promp t" and =>
page 127, "Sy stem limi ta tions ".
& WARNING
Improper u se of the adaptive cruise control can cause colli sion s,
othe r accidents and serious personal injury.
• Never drive at speeds that are too high for traffic, road and
weather condition s.
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safel y. The adaptive cruise control cannot brake the
vehicle safely when you follow another vehicle too closely . Alway s
remember that the adapti ve cruise control has a braking power
that i s only about 25% of the vehicle 's maximum br aking ability,
the automatic b rak ing function cannot bring the vehicle to a stop.
• Never use adaptive cruise control on roads where you cannot
drive safely at a steady speed , including city , stop-and-go or heavy
traffi c, on winding road s or when road cond ition s are poor (for
e x ample , on ice, gravel, in fog, heavy rain or on wet roads that
in crea se the risk of hydroplaning).
• The rada r sensor' s
vis io n can be reduced by rain, snow and
heavy spray . This can re sult in vehicle s driving ahead being inade­
qu ately detected or, in some circumstances , not detected at all. If
necessary, t ake action yourself! ..,

& WARNING (co ntinued )
• Always turn off adaptive crui se control when entering turn
lanes, highway ex it lanes and con struction zones or similar situa­
tions because the vehicle will automatically accele rate to the
stored speed .
• Never rest your foot on the accelerator pedal, especially when
the adaptive cruise control is being u sed because doing so will
override the braking function and prevent the brakes from being
applied by the system when it detect s a situation when the brake s
must be applied.
• Alway s remember that the adaptive cruise control has limits -
it does not react when you drive towards an obstacle or something
else on or near the road that is not moving, such as vehicles
stopped in a traffic jam , a stalled or disabled vehicle .
• Always remember that the adaptive cruise control cannot
detect a veh icle th at i s driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and bicy­
cles .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off.
• The Electronic Stabilization Program (ESP) and the Ant i-Slip Regu ­
la tio n (A SR) c anno t be de activated when the adaptive cruise cont rol
is sw itched on .
If the ESP and the Anti -S lip Regulation (ASR) has been
de activ at ed an d yo u the n switch on the ad apt ive cruise cont rol, the
ESP fu nction w ill also be activated automatically.
• Dam age cau sed by accide nts (e.g. if the vehicle is dam age d whe n
park ing) can affect the rada r sensor settings. This can cause t he
sys tem to malfunc tion or switch off comple tely.
• The radar sensor cover is heated. In w inter conditions, you should
st ill ch eck befor e dr iv in g to make s ure i t is free of ice and s now. If
necessary, clean the area nea r the rada r sensor carefully=>

• If you push the lever up to increase (or down to reduce) speed
when no speed has been set previously.
• If you push the lever up to increase (or down to reduce) speed and
this speed is outside the range from 20 to 95 mph (Canada mode ls:

The text message ACC functionality limited appears when the ACC
system does not detect any objects over an extended time period. For
the time being, the d istance to veh icles up ahead is not being

. The ACC system is not switched off, so increased alertness
is required. The following may be reasons for the text message ACC
Functionally limited:
• The ACC sensor is dirty. The ACC system is not reacting, or is not
reacting correctly, to vehicles traveling ahead.
• It is possible that you are driving on a road with very light traffic
without anything at the s ide of the road (e .g . guard rails, traff ic s igns,
trees). As soon as a vehicle is detected by the system again, it returns
t o its contro l range and the text message disappears.
The ACC sensor is located in the r ig ht front trim grille
=> page 116,
fig. 113. If there is a loss of operation due to heavy contamination,
this area should cleaned to restore proper operat ion .
ACC not available
The text message ACC not available appears, for examp le, if the
t empe rature of the brakes is excessive. Adaptive cruise control is
temporarily not available. A warning tone sounds as a rem inder .
ACC not available!
The text message ACC not available! appears in the event of a
ma lf unct ion. Adaptive cruise control is turned off. A warn ing tone
sounds as a reminder . Have the system inspected by a qualified deal­
ersh ip.
ACC sensor blocked !
The text message ACC sensor blocked ! appears when the ACC System
can no longer guarantee safe detection of objects. Adaptive cruise
control is turned off. A warning tone sounds as a reminder.
To decide whether it is necessary to switch off the ACC (ACC sensor
blocked
!) or if it is only a temporary condition (ACC Functionally
limited), the system w ill also takes into consideration the outside
temperature and/or the windshield wiper operation .
Th e ACC sensor is d irty or blocked (e.g. leaves, snow).
The sensor should be cleaned to restore prope r sensor funct ion

[I) Tips
• If the adaptive cruise control initiates brak ing, the hydraulic brake
system is under pressure. Therefore, the brake pedal distance is
shorter and the peda l "feels" harder.
• Adaptive cruise control is switched off after pressing the foot­
brake. The speed saved up this poi nt can be resumed.
• To resume the saved speed, release the brake pedal and press the
control lever:::::,
page 120, "Turning adaptive cruise control off
temporari ly".
• If you use the accelerator to go faster than the speed of the object
ahead of you, the
driver intervention prompt will not be accompa­
nied by a warn ing s ignal.
• If the speed you prev iously set is exceeded, the indicator light in
the speedometer will switch off .•

General information
Some driving situations which affect the function of the
radar sensor are described below.
When driving, the adaptive cru ise contro l is governed by physical and
system-specified limits. Also, under certain circumstances, the ACC
system may react unexpectedly or late from the driver's point of view.
Therefore, a lways be attentive and intervene, if necessary:
• when driving around curves:::::,
page 128
• when vehicles in front are not in line with your vehicle:::::, page 128
• whe n other ve hicles are changing lanes:::::, page 128
• when other vehicles are difficult to detect:::::, page 129.
& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray . This can result in vehicles driving ahead being inadequately
detected or, in some circumstances , not detected at all. If neces­
sary, take action yourself!•

The Audi braking guard is active from a speed of approx. 20 mph
(30 km/h) and works within the system limits=>
page 12 7 even when
the adaptive cruise control is deactivated.
A radar sensor is built into the front of the vehicle=>
page 116,
fig. 113. The system is intended to measure the distance to reflective
surfaces. If a measurement is not possible, the system does not
respond.
When the measurement has taken place, the system can assess a
hazardous situation, when a vehicle ahead suddenly brakes or when
your own vehicle is dr iving at high speed towards a much slower
vehicle ahead. As soon as the system assumes that a possible colli­
sion w ith the vehicle ahead can only be avoided by immediate all-out
braking or by an avoiding maneuver, a warning appears .
Th e system has a pre-set response time to be able to warn in good
time. This system response time is automatically reduced if you accel­
erate actively, for example to join a highway. Braking, transverse
acceleration and the steering angle can lead to a reduced system
response time. The warning is deactivated if you begin to overtake
with full accelerat ion.
The system draws your attention to two different hazardous situa ­
tions:
Distance
Th e distance wa rning is issued in the event of inadequate distance to
the vehicle ahead a period of more than S seconds. If the distance is
less than 30 feet (9 meters) at SO mph (80 km/h), for example, an
optical display is faded in on the instrument cluster=>
page 129,
fig. 132.
If the vehicle ahead brakes sharply, a collision cannot be avoided,
even in the case of an immediate response. In this case, increase the
distance to the vehicle ahead.
Speed
If there is a much slower vehicle ahead in your lane, or if the vehicle
ahead brakes sha rply, the Audi braking guard calculates the point from which a collision can only be avoided by all-out braking or by an
avoiding maneuver. If a warning does sound, a possible collision with
the vehicle in front can be avoided through an evasive maneuver or by
braking.
Th e warn ing is given in two stages:
• Pre-warning: An optical display appears in the instrument cluster
and a warning tone sounds.
• Acute warning: If you do not respond to the pre-warning, the
second stage, the acute warning, is issued. A brake jolt reminds you
to concentrate on the road again.
Under heavy breaking, brake assist =>
page 245 also helps you obtain
maximum braking effic ien cy.
& WARNING
Always pay attention to traffic, even when the Audi braking guard
is switched on. You are always resp onsible for
your speed and the
distance between your vehicle and other vehicles.
• Always keep the legally stipulated safety distance between
your vehicle and the vehicle ahead -danger of accident!
• The Audi braking guard does not respond outside the system
limits, for example if you approach a stationary obstacle (end of a
traffic jam or breakdown vehicle).
• Please observe that the Audi braking guard is subject to restric­
tions in narrow bends due to the field of vision of the radar sensor.
This may possibly lead to obstacles not being detected.
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray . This can result in vehicles driving ahead being inade­
quately detected or, in some circumstances, not detected at all.
Always watch where you are driving.
• Reflecting objects such as e.g. crash barriers or the entrance to
a tunnel may impair the function of the radar sensor.•

Audi lane assist ml
----------------
Not ready: The yellow indicator light shows that the system is
turned on but unable to send a warning. This can be due to the
following:
• Th ere are no boundary lines, or there is only one boundary line
present.
• The boundary lines are not detected (e .g . due to snow, dirt, wet
conditions or light shining into the camera lens).
• More than two boundary lines (such as at construction sites) are
located in the vehicle's lane.
• Th e vehicle's speed is below the speed needed to activate it, which
is about 40 mph (65 km/h) .
• Th e lane is narrowe r than about 8
ft. (2.5 m), or wider than about
16 ft. (5 m).
• The curve is too sharp.
Notes on the instrument cluster display
When the lane assist turns off automatically, the instrument cluster
indicator goes out and one of the fo llowing messages appears on the
display:
Audi lane assist not available: currently no sensor vision
This message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• Th e exte rior side of the camera viewing window=>
page 132,
fig. 134 is covered with dirt or ice. Clean this part of the windsh ield.
• Th e came ra viewing window is fogged up on the inside. In this
case, wait until the fog disappears before turning lane assist on
again.
• Th e system was unable to detect boundary lines over an extended
period of time due to road conditions (such as snow-cove red lanes).
Do not turn lane assist on aga in until the lines can be more easily
detected.
