[ i ] Tip s
• In the case of an intentional loss of air pressure, for examp le,
when re -adjusting tire pressure, th is has to be stored again after ­
wards ~ page
43.
• Tire pressure must only be adjusted wh en the temperature of the
tires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system~ page
43.
• After changing a wheel you have to adjust the tire pressures on
a ll whee ls . In addi tion , you must then initialize the new tire pres­
sures in the tire pressure mon itoring system ~ page

Adjusting and storing the tire pressure
(step 1)
Only when the specified pressure is properly entered into
the system, is the tire pressure monit oring system prop­
erly calibrated for accurate indications.

Technical data

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
vehic les, the tire pressure label is located on the driver 's side 8-
pillar. On Canada vehicles, the tire pressure label is located either on
the driver's side 8 -pi llar or insid e 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 conditions , please see chapter
=> page 271.
• The tire pressure monitoring system he lps the driver to keep an
eye on tire pressures . But the driver st ill has t he responsibi lity for
maintaining the correct tire pressure .•

Driver inf orma tion d ispl ay
Your tire change is incomplete if you do not access the Driver Infor­
mation System menu, and select and confirm
Wh eel ch ange. You
must do this each time to change a tire . The procedure can take up
to 20 minutes driving time. During this time, the sensors are read ­
justing to the new wheel/tire combination, and the new pressures are stored.
During the learning phase, the tire pressure monitoring system is
not available. •

Malfunctions
A malfunction can have various causes.

Syst em m alfu nct ion
If the 'warning light in the instrument cluster flashes for approxi ­
mately one minute and then remains continuously illuminated and
additional ly the --, -=> fig. 35 symbol appears in the display, the
tire pressure monitoring system is not available. This can have
various causes.
• If the message appears a t the end of the learning phase, the
system cannot recognize the wheels installed 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 45, "Changing a wheel"
procedure was not activated =>
page 45.
• Audi replacement parts were not used.
• If snow chains are being used, system function can be compro ­
m ised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be ava ilable
because of a radio malfunction.
• Transmi tters with the same frequency, such as radio head ­
phones in the vehicle or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields.
• Try to find the cause of the interference, and then perform the
=>
page 45 , "Changing a wheel" procedure one more time . If this not
e liminate the prob lem, contact your authorized Audi dealer for
assistance .
• Do not use commercial ly availab le tire sealants . Otherwise, the
e lec trical components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system wi ll have to be rep laced by a qua lified workshop .•

On the road
Steering
Adjusting the steering wheel column
The height and reach of the steering wheel can be
adjusted.
First, adjust the driver's seat correctly.
Fig . 135 Lever under
the steering column
-Push the lever~ fig. 135 -Arrow- ~& .
- Move the steering wheel to the desired position.
- Push the lever against the steering column unt il it locks.
Th ere mus t be at least 10 inches (25 cm) betw een your br eastbone
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 96, "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
125 cm) between your breastbone and the
steering wheel=> page 148, fig.
154. If you cannot maintain this
minimum distance the airbag system cannot protect you properly.
• If physical limitations prevent you from sitting 10 inches
125
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. •

Acoustic park assist
A pplies to vehicles : with 4 -ch an nel a co ustic park ass is t
Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car.
How it works
The acoustic park assist warning system (4-channel acoustic park
assist) uses ultr asonic sensors to warn yo u when you are
backing
your vehicle close to an obstacle . The system 's 4 sensors are located
inside the rear bumper .
Acti va ting
The rear acoustic park assist is ac tivated whenever you shift into
Reverse . You will hear a warn ing tone when the system is on .
Reverse
With the car backing up in reverse gear, the col lision warning sound
sets in at the fol lowing
approximate d istances to obstacles :
straight aft 5ft(1.5m)
angling aft off vehicle corners 2 ft (0
.6 m)
As the dis tance shr inks, the time interva l between the audible tones
grows shorter.
The sound changes to a continuous tone as soon as the remaining distance to an obstacle closes to less than about 1 ft. (0 .3 ml. The
steady tone cautions you that you have backed up hazardously
close and you ris k co llision by backing up any further .
Malfunctions in the system
If a warning tone is audible for about five seconds when you turn on
the ignit ion, there is a malfunction in the system . Have the prob lem
corrected by your authorized Audi dea ler. _,.
