Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significantly
under-inflated . The TPMS on ly provides a low tire pressure warning
and does not reinflate your tires .
Accordingly, when the low tire pressure telltale illumin ates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under ­
inflated tire causes the tire to overheat and can lead to tire failure.
Under -inflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping ability .
0 Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's responsibility to maintain correct
tire pressure, even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale. .,,_

Driver inf ormati on displ ay
<£> For th e sak e of th e environm ent
Driving w ith under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tip s
• Each tire, incl udin g the sp are, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 317.
• The factory supplied spare whee l is equipped with a sensor for
the tire pressure monitoring system. As long as the spare whee l it
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system he lps the driver to keep an
eye on t ire pressures. But the driver stil l has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature .
• When tires are replaced, the sensors and valves shou ld not be
detached or exchanged. Only the valve core needs to be rep laced
and, i f necessary, the valve and the wheel electronics replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire p ressure monitoring system.
Otherwise the system w ill register a ma lfunction and a fault
message will be displayed . For more information, contact your Audi
dea ler.
• Adjust the tire pressure and store the pressure in the tire pres­
sure monitor ing system to the load you are carry ing. •

[ i ] Tip s
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after ­
wards :::::,
page 45.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The ye llow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system=:>
page 45.
• After changing a wheel or rep lacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels . In addition, you
must then initialize the new tire pressures in the tire pressure moni ­
toring system=:>
page 46. •
Storing tire pressures
Correct storage of specified pressure is the basic require ­
ment for reliable tire pressure monitoring.
Fi g. 27 Car: Tire pres ­
s ur e m onit oring
syste m
In order for the tire pressure monitoring system to operate
appropriately, you have to re -save the specified pressures in
the MMI whenever you adjust tire pressures, for example
when the load condition of your vehic le changes. Proceed
as follows :
Controls and equip ­
ment
Dr ive r informat ion di spl ay
C orr ec ting tir e pr essur e
Check the pressure in the tires.
- Adjust air pressure as needed to comp ly with t he infor­
mation on the label located either on the driver's side 8-
pillar (visible when the door is open) or inside the fuel
filler flap.
Sav ing t ire pressur es
- Turn o n the ignition .
- Press the
I CAR I function button.
Select

Select
Tire pressure mon itor ing .
Select Store curr . tire press ures~ fig . 27.
All pressure warning indicators in the disp lay will be canceled.
Following each intentional change in specified pressures , tire pres­
sures must be resaved.
After the pressures are saved , the tire pressure monitoring system
measures the current tire pressures and saves them as the new
specified pressures.
[ i ] Tips
• The tire pressure is shown on the tire pressure label. On USA
vehicles, the tire pressure labe l is located on the driver's side B ­
pillar. On Canada vehicles, the tire pressure label is located either on
the driver's side B -pillar or inside the fuel filler f lap . T he tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured. For recommended tire pressures for normal load conditions, please see chapter
=> page 317. .,.

Roof rack
First things first
A roof rack can be fitted to carry additional luggage on
the roof.
- Always read and follow the i nstructions provided by the
roof rack manufacturer when t he roof rack system must
be installed.
If you are transporting luggage or other objects on the roof, please
note the following:
• Your vehicle has specially designed aerodynamic roof rails. On ly
install a roof rack specifically designed for your model. Contact the
nearest Audi dealer for information on approved modu lar roof racks
f or your vehicle.
• These approved roof racks are the basis for a complete roof rack
system. Addit ional attachments for the basic roo f rack are neces­
sary to safely transport luggage, bicycles, surf boards, skis or small
boats . All necessary hardware for these systems is availab le at your
authori zed Audi dealer.
• We recommend that you keep the installation instructions for
your roof rack system together with your Owner's literature in the
veh ic le.
Wh en should th e roof ra ck b e remo ved?
• Before going through an automatic car wash (it is best to ask the
car wash operator for advice).
• When not in use, to reduce fuel consumption, wind noise and to
guard against theft .
Controls and equip ­
ment
& WARNING
• Use of an unappr oved roof r ack or in corre ct mounting of an
a pp ro ved roof r ack can cau se the roof rack or the ite ms attached
t o it t o fa ll off th e ro of ont o th e road .
• Obj ec ts falling fr om the roof of a v ehic le can c au se a cr ash and

0 Note
• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or moun ting structures not approved by
Audi for your vehicle. The same applies to damage resulting from
incorrect roof rack installation.
• Always check the roof rack mountings and hardware before each
trip and during a trip to make sure everything is securely tightened .
If necessary , retighten the mountings and check the entire system
from time to time.
• After mounting a roof rack system, or when you transport
objects on the roof of your vehicle, the height of the vehic le is natu­
ra lly increased . Be careful when driving under low bridges or in
parking garages for examp le . This could cause damage to the load
and even the vehicle itself. •

The air outlets are actuated either automatically or manually
depending on the operating mode selected. Heated or unheated
fresh air, or cooled air flows from the vents.
The air outlets to heat the rear footwell are located under the front
seats .
[ i] Tips
If the climate control system is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars. To achieve adequate cooling, you should never close the
outlets completely. •
Using climate control economically
Using the climate controls prudently can help save fuel.
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should use the air conditioner only when necessary. Also please
note the following points:
- If you want to save fuel, activate ECON.
- If you are going to drive with the windows open, use
ECON.
If the vehicle is extremely hot due to the heat of the sun,
briefly open doors and windows.
~ For the sake of the environment
By reducing the amount of fuel you use, you also reduce the amount
of pollutants emitted into the air. •
