Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
Controls and equip ­

Fig . 23 Display: speed
warning system
Driver inform ation system
The speed warning system warns the driver if he exceeds a previ ­
ously stored maximum speed. A warning tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 6 miles per hour (10 km/h). At the same time, a warning symbol appears in the
display=> fig. 23.
The speed warning system has
two warning thresholds that func ­
tion independently of each other and that have somewhat different
purposes :
Speed warning 1 )f ..._ (Canada models)
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
J I ,.... (Canada models) in the warning 1
display appears when you exceed the maximum speed . It goes out
when the speed falls below the stored maximum speed.
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is deleted .

Speed warning 2 ...,,, /
e!. (Canada models)
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
The speed warning 2 symbol, / ) (Canada models) appears in the
display when you exceed the stored speed limit. Unlike warning 1,
it wi ll not go out until the vehicle speed drops below the stored
speed limit .

telltale. When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle
starts up as long as the malfunction exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
a lternate tires and wheels al low the TPMS to continue to function
proper ly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the t ire pressure monitoring system senses a s ignificant
loss of air pressure in one or several tires, text messages and yel low
symbo ls appear in the instrument cluster display to a lert the driver.
The warning light in the instrument c luster comes on when the
tire is significantly underinflated
=> page 17.
The warning light
malfunction . also
illuminates in the case of a system
Be aware that tire pressure is also dependent on the temperature of
the tire . For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1 .5 psi (0. 1 bar) . The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure on ly when they are
cold , when the temperature of the tires
is roughly the same as the ambient air temperature.
In order to keep the tire pressure monitoring system properly ca li­
brated, tire pressure on all four tires should be checked at regular intervals, adjusted if necessary and saved in the proper setting
(recommended
pressure)=>
page 44.
The tire pressure is shown on the label located on the driver 's side
B -pillar (visible when the door is open) .
& WARNING
• When the tire pre ssure monitor ing system warn ing light i s lit ,
one or more of your t ir es is s ignificantl y unde r-inflated . You should
s top and check your tire s as s oon as po ssible , and inflate them to
the p rope r pre ss ure as indi cated on th e vehicl e's tire pr essure
label
=> pag e 242. Driv ing on a s ignific antl y un der-inflated t ire
c a use s the tire to overhe at and can le ad to tire fa ilure. Unde r-inf la­
ti on also i s lik el y to impair the vehicle' s handling and stopping
ability .
• Do not adju st t ir e pressur e wh en t ire t emp erature is exce ssiv e.
Thi s could le ad to seriou s tire dam age and even cau se the tire t o
bur st, w ith the addition al dan ger of an accident.
W For the sake of the environment
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire should be checked month ly when the temperature of
the tires is abou t the same as ambient air temperature and s et to the
recommended inflation pressure as specified on the tire pressure
label =>
page 242.
• The factory supplied spare whee l is equipped with a se nsor for
the tire pressure monitoring sys tem. As long as the spare wheel is
n ot mounted, the tire pressure of this tire wil l not be monitored.
• T he tire pressure monitoring system he lps the driver to keep an
eye on tire pressures . But the driver still has the responsibility f or
maintaining the correct tire pressure . .,_

• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambien t air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged. The valve core, nut, valve sea ling and sea l washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be rep laced .
• 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 pressure monitoring system.
Otherwise the system will register a malfunction 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 monitoring system to the load you are carrying .•
Significant loss of air pressure \-,1
The yellow symbol appears in the event of a significant
loss of air pressure.

[ i ] Tips
• 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 44.
• 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 stored in the system=>
page 44.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on a ll wheels. In add ition , you
must then initia lize the new tire pressures in the tire pressure moni ­
toring system =>

tire pressure monitoring system is not available. This can have
various causes .
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
installed.
• A wheel sensor or other component may have failed .
• During initia lization the system has detected more than 4 wheels
on the vehicle, for example whi le driving next to another car with a
tire pressure monitoring system.

• A wheel change was made but the button => page 44, fig. 29 was
not pressed .
• Audi replacement parts were not used.
• If snow chains are being used, system function can be compro­
mised due to the shielding 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 vehic le or radio equipment, can cause a temporary
disruption of the system through excessive e lectromagnetic fields.
• Eliminate the interference if possible/if you can and then
proceed as follows: Turn off the engine for 20 minutes . Then drive
another 10 min. If the warning light comes on again, you should
contact your authorized Audi dealer immediately to have the
problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
