If luggage or cargo is to be ca rr ied on the roof,
you m ust observe the fo llow ing:
- On ly a specially designed roof rack may be used
on you r vehicle. These roof racks are the bas is
for a comple te roof rack system. Additional at­
t achments/ca rrier systems are necessary to
transpo rt luggage and spo rts equipment. We
recommend roof racks and attachments from
the Audi Genuine Accessories program.
- When installing the roo f rack, make sure that it
is mounted only at the designated points on
the roof
c::> fig. 88 or c::> fig. 89.
- The max imum permissib le roof load for your
vehicle is 200 lbs (90 kg). The roof load is the
total of the weight of the roof rack, the attach­
ments and the cargo you are carrying. However,
please note the permissib le load of the carrier
system being used, the permissible axle loads
and the permissible total vehicle weight
c::> page 3 79.
.&_ WARNING
- Follow the install ation instru ct ions prov ided
w ith the roof rack system.
If you do not se­
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and ca use an accident.
- The risk of an accident increases when using
a roof rack system, because it changes the
driving characterist ics by shifting the center
of grav ity and/or the increasing the surface
area exposed to wind. Adapt your driving
and speed to the current cond itions.

Warm and cold
Warm and cold
Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof * are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode f unctions except for
defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem­
perature .
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y recognit ion
The climate control settings are automatically
stored and assigned to the remote contro l key
that is in use .
76
® For the sake of the environment
-If you would like to reduce fuel consump­
t ion, sw itch the air conditioning
off. This
will also reduce emissions.
- In veh icles with a diesel engine, you can
switch the auxiliary heater
off in the Info­
tainment system.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system can
dr ip and form a pudd le of water under the
vehicle . This is norma l and does not mean
there is a leak.
- The energy management system may tem­ porarily switch
off certain functions, such as
the seat heating* o r rear window defogger.
T hese systems are ava ilable again as soon
as the ene rgy supply has been restored.

engaged, for example when you notice that the 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 ­
sumpt ion to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficiently
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fuel unnecessari­
ly.
Applies to: vehicles with manual transmission
Shift as soon as possible from first to second
gear. S hifting to the next highest gear at approxi­
mately 2,000 RPMs if poss ible is recommended.
Applies to: vehicles with automatic transmissions
Press down on the acce le rator peda l 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. Driving more slowly saves fuel.
Reduce idling time
The Start/Stop system* he lps 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 cross ings and long
r ed lights. Stopping the engine for 30-40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
It takes a very long time in idle to warm the en­
g ine up to operating temperature. Wear and
emissions are especially h igh in the wa rm-up
phase . Therefore, you should begi n driving im­
mediately a fter starting the engine . Avoid high
RPMs while do ing this .
Have maintenance performed regularly
By having maintenance performed regu larly on
your veh icle, yo u ca n he lp to reduce f uel con­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l-
Driving
so impacts fuel consumption . A poorly main ­
tained engine can lead to fuel consumption that is 10% higher than norma l.
Avoid short trips
The eng ine and exhaust cleaning system must
reach their optimal operat ing temperatu re to ef­
f ectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fue l. The engine reaches operating
temperat ure and consumption normalizes on ly
after approximate ly 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct press ure
~ page 344. The
fuel consumption can increase by 5% if the pres­
s u re is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures wi ll also
l ead 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
S in ce eve ry po und of ext ra weight increases f uel
consumption , a quick inspection of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62 -75 mph (100 - 120 km/h) .
Save energy
The eng ine drives the generator, which generates
electric ity; the fuel consumpt io n also incr eases
with the demand for electr icity. The refore, switch
electrical eq uipment off when you no longer
need it . Examples of equipment that uses a lo t of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights shou ld come on to
indicate improper operation, they would go

Audi pre sense
Introduction
A pp lies to: ve hicles w ith Audi p re se nse
W ithin the limits of the system, the pre sense
functions can initiate measures in particularly
dangerous situations to protect the veh icle pas­
sengers and other road users .
- Due to the interlinking of various vehicle sys­
tems, crit ical dr iving s ituations can be detected
by
pre sense basic and measures for preventa ­
tive occupant protection are can be initiated .
- The
pre sense front system uses the data from
the adapt ive cruise control* radar sensors and
the camera to calculate the probab ility of a col­
li sion. Withi n the limits of the system, an im­
pending collision with vehicles can be dete cted
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec­
essary. If needed, it can initiate a partial or full
deceleration to reduce the co llision speed or to
avo id the collision under certain c ircumstances .
In conjunct ion with pre sense basic/rear, the
front safety belts are also revers ibly tensioned
when needed . The pre sense front is also active
whe n adapt ive cruise control* is swit ched off.
- Pre sense rear contains pre sense basic func­
tions. It uses the data from the side assist* ra­
dar sensors and calculates within the limits of
the system the probab ility of a rear end coll i­
s ion with the vehicle behind you. Pre sense rear
is also active when side assist* is switched off.
- Within the limits of the system,
pre sense city
uses the camera data and can detect an im ­
pending collision with vehicles and pedestrians.
In this case, the system warns the driver visual ­
ly, acoustically and with a jerk on the brakes if
necessary. If needed, it can initiate a full decel­
eration to reduce the collision speed or to avoid
120
the collision under certa in circumstances . In
conjunction with pre sense basic/rear, the front
safety belts are also reversibly tensioned when
needed .
A WARNING
-
Read the general information inc> & in Gen-
eral information on page 109,
c> & in Gener­
al information on page 130.
(D Tips
- Certain pre sense funct ions sw itch off when
dr iving in reverse.
- The pre sense functions may not be availa­
ble if there is a malfunct ion in the ESC sys­
tem or the a irbag control module.
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's airbag is deactivated .
- Switch the pre sense off when you are not
using public streets or when loading the ve­
hicle onto a vehicle carrier, tra in, sh ip or
other type of transportation. This can pre­
vent an undesired intervention from
the pre
sense system.
Audi pre sense basic
Description
App lies to : vehicles wi th Audi pre sense basic
The pre sense bas ic functions are activated at a
speed of approx imately 20 mph (30 km/h) or
higher .
The following functions can be triggered under certain condit ions w ith in the lim its of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy brak ing): the front safety belts
have reversib le be lt tens ioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger again.
- Closing the windows and sunroof* .
-
