& WARNING
• When the tire pre ssure monitoring sy stem warning light i s lit ,
one or more of your tires is sign ifi cantly under-inflated . You should
s top and check your tire s as soon as possible , and inflate them to
the p rope r pres sure a s indicated on the vehicle's tire pre ssure
label
~ page 297 . Driving on a significantly under -inflated tire
c ause s the t ire to overheat and can lead to tire failure . Under -infla ­
tion also is likely to impair the vehicle's handling and stopping
ability .
• Do not adjust tire pre ssure when tire temperature is excessive.
Thi s could lead to serious tire damage and even cause the tire to
burst , with the additional danger of an ac cident .
<£' For the sake of the environment
Driving wi th under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire should be checked mon th ly when cold and set to the
recommended inf lat ion pressure as specified on the tire pressure
table~ page 297 .
• The tire pre ssur e monito ring system he lp s the drive r to kee p
t rack of the tire pressures. But the d river s til l has the responsibi lity
for maintaining the correct tire p ressure .
• Tire pressure must only be adjusted when th e temperature of the
t ires is about the same as am bien t air temperatu re .
• When tires are replaced , the sensors and va lves must not be
detached or exchanged. Only the valve co re needs t o be rep laced
and, if necessary, the valve and the wheel e lectronics replaced.
Controls and equip ­
ment
Driver information display
• If you should put different whee ls and tires on your vehic le (e .g.
win ter wheels a nd ti res), you must be certa in that the wheels a nd
tires are compatible with the t ire pressure monitoring system .
O therwise the system will register a ma lfunction and a fau lt
message will be displayed. For more information, contact your Audi
dea ler .•

After a few seconds , the message disappears again. If you would
like to show the message again, press the
I CH ECK I button.
[ i ] Tips
• In the case of an intentional loss of air pressure, for examp le,
when re -adjusting tire pressure, this has to be stored again after ­
wards~ page 48.
• Tire pressure must only be adjusted when the temperature of the
t ires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is s tored in the system
~ page 48 .
• After changing a wheel you have to adjust the tire pressures on
all wheels. In addition, you must then initia lize the new tire pres­
sures in the tire pressure monitoring
system ~ page 50. •

@ to select the Sto re pre ssure s option
~ page 49, fig. 41.
Following each intentional change in specified pressures , tire pres­
sures must be resaved .
Af ter 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
vehic les, the tire pressure label is located on the driver's side 8-
pillar. On Canada vehicles, the tire pressure labe l is located either on
the driver's side 8 -pillar or inside the fuel filler flap . The 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 cond itions, please see chapter
~ page 297.
• The tire pressure monitoring system he lps the driver to keep an
eye on tire pressures. But the driver stil l has the responsibility for
mainta ining the correct tire pressure. •

additional ly the => fig. 44 symbol appears in the display, the
tire pressure monitoring system is not available . This can have
various causes.
• If the message appears at the end of the learning phase, the
system cannot recognize the wheels insta lled on the vehicle . This
can be because one or more wheels without a wheel sensor were
installed .
• A wheel sensor or other component may have failed.
• The system has detected more than 4 wheels in the vehicle, for
example while driving beneath another car with tire pressure moni ­
toring system .
• A tire was changed but
the => page 50, "Changing a wheel"
procedure was not activated
=> page 50.
• Audi replacement parts were not used .
• If snow chains are being used , system function can be compro ­
mised due to the shie lding properties of the chains .
• The tire pressure monitoring system may not be available
because of a radio malfunction .
• Transmitters with the same frequency , such as radio head ­
phones in the vehicle or radio equipment, can cause a temporary
dis ruption of the system through excessive el ectromagn etic fie lds.
• Try to find the cause of the interference, and then perform the
=> page 50, "Changing a wheel" procedure one more time . If this not
e liminate the prob lem , contact your authorized Audi dea ler for
assistance .
• Do not use commercially available tire sealants. Otherwise , the
electrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system will have to be replac ed by a qualified workshop. •
Technical data

& WARNING
Never use daytime running lights to see where you are going . They
are not bright enough and will not let you see far enough ahead for
safety , espe cially at dusk or when it is dark . Be aware of changes
in outside light conditions when you are driving and respond by
switching on your lo w beams
io.
0 Note
• With the light switch at the O or :oo, position , only your front fog
lights remain turned on when it turns dark outside . Even though
your instruments appear well lit, the road ahead of you is not. The light pattern provided by fog lights alone is not sufficient for safe
driving in poor light or darkness. Therefore:
• Always be aware of changes in outside light conditions while
you are driving. Respond in time to fading daylight by turning the
light switch to position
io (or "AUTO" if your car is equipped with
th is featu re)
to turn on your headlights .•

Adjusting the steering wheel column
The height and reach of the steering wheel can be
adjusted.
Fig . 142 Lever under
the steering column
First, adjust the driver's seat correctly.
- Push the
lever => fig. 142 -Arrow- =>& .
Move the steering wheel to the desired position.
- Push the lever against the steering column unt il it locks.
There must be at least 10 inches (25 cm) between your breastbone
and the center of the steering wheel. If you cannot sit more than 10
inches (25 cm) from the steering wheel,
we recommend that you
investigate whether adaptive equipment is available to help you
reach the pedals and increase your seating distance from the
steering wheel. For detailed information on how to adjust the driver's seat, see
=> page 97, "Power seat adjustment"
.
& WARNING
Improper use of steering wheel adjustment and improper seating
position can cause serious personal injury .
• Adjust the steering wheel column only when the vehicle is not
moving to prevent loss of vehicle control.
• Always make sure that the adjustment lever is securely pushed
up so that the position of the steering wheel cannot be changed
unintentionally when the vehicle is moving.
• Adjust the driver's seat or steering wheel so that there is a
minimum of 10 inches (25 cm) between your breastbone and the
steering
wheel ~ page 168, fig. 162. If you cannot maintain this
minimum distance the airbag system cannot protect you properly.
• If physical limitations prevent you from sitting 10 inches (25
cm) or more from the steering wheel, check with your authorized
Audi dealer to see if adaptive equipment is available.
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in an
accident. Always make sure that the steering wheel is pointed
towards your chest .
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag inflates.
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions inside the steering wheel rim or on
the steering wheel hub. Holding the steering wheel the wrong way
can cause serious injuries to the hands, arms and head if the
driver's airbag inflates.

Cruise control
General information
The cruise control system allows you to maintain a
constant speed.
The cruise control system allows you to maintain and constant
driving speed when driving faster than 18 mph (30 km/h) -to the
extent this is possible with the given engine power and braking
characteristics. This allow you to take your foot off the "gas" and
rest it, especially on long trips .
The indicator light CRUISE (USA)/
•l'l (CDNl in the instrument cluster
illuminates when the system is on .
& WARNING
• To help keep the vehicle under control, do not use the cruise
control system when driving on winding or slippery roads (as
caused by heavy rain or loose gravel on the road surface), or in
heavy or varying traffic.
• Only use the cruise control when traffic, road and weather
co nd itions allow you to drive at a steady speed.
[ i] Tips
The cruise control cannot maintain a constant speed when driving
downhill. The vehicle will accelerate under its own weight. Down­
shift to a lower gear or use the brakes to slow down .•
Storing a speed
You must set and then store a vehicle speed using the
cruise control.

- Accelerate until you reach the driving speed you want to
store.
- Pull
lever © towards the steering wheel G) => fig. 145 to
switch the system on.
- Press button

After you release button @, the current vehicle speed is stored and
maintained .•
Changing a stored speed
You can change a stored speed.
Accelerate (faster)
-Lift lever © toward 0 => fig. 145 .
- Release the lever to store the new speed.

& WARNING (continued)
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on ,
immediately install the rear -facing child safety seat in a rear
seating posit ion and have the airbag system inspected by your
Audi dealer .
• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-sensing mat in the seat and register more weight
than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
serious or even fatal injury to the child.
• If , in exceptional circumstances , you must install a forward ­
facing child restraint on the front passenger seat , always move the
seat into its rearmost position in the seat 's fore and aft adjust­
ment range , as far away from the airbag as possible. The backrest
must be adjusted to an upright position . Make sure that the
PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on .
& WARNING
• If the PASSENGER AIR BAG OFF light does not go out when an
adult is sitting on the front passenger seat after taking the steps
described above , make sure the adult is properly seated and
restrained at one of the rear seating positions .
• Have the airbag system inspected by your Audi dealer before
transporting anyone on the front passenger seat .
