ment", before opening the engine hood and checking the brake
fluid.
• Driving with low brake fluid is a safety hazard! Stop the car and
get professional assistance .
• If the brake system warning/indicator light illuminates
together with the ABS warning/indicator light, then the ABS
system is malfunctioning. The rear wheels could quickly lock up
when you apply the brakes. This could lead to loss of control _and
your vehicle could slide! Drive carefully to the nearest authorized
Audi dealer and have the malfunction corrected. •
Engine cooling system malfunction _t_
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the _t symbol in the display flashes, then either the
engine coolant
temperature is too high, or the coolant level
is too low. In addition to the symbol, the following message
also appears in the display:
SWITCH OFF ENGINE AND CHECK COOLANT LEVEL
-Pull off the road and stop the vehicle .
Turn off the engine.
Check coolant level =>
page 228.
Add coolant if necessary => page 228.
-Continue driving only after the engine coolant

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.

symbol with message
If the • warning light in the instrument cluster comes on
and then the ( symbol appears in the display~ fig. 28,
pressure in at least one t ire is too low.

[ 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 =>

Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring.
F ig . 29 S ET -butt on:
T ire pressure mon i­
t or ing syste m
In order for the tire pressure monitori ng system to operate
appropr iately, you have to re-save the specified p ressures
whenever you adjust tire pressures, for example when the load co nd ition of your vehicle changes. Proceed as fo llows:
Corr ecting tir e pr es sure
Check the pressure in the t ires.
- Adjust air pressure as needed to comply w ith the infor­
mat ion on the label located on the driver's side B -pillar
(visible when the door is open) .
Saving tire pressures
-Turn on the igniti on.
- Press the button :::> fig. 29 for app rox imately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three t imes .
All pressure warning indicators in the d isplay will be canceled. Following each intentional change in specified pressures, ti
re pres ­
sures must be resaved.
After the pressures are saved, the tire pressure monito ring system
measures the current tire pressures and saves them as the new
spec ified pressures .
[ i ] Tip s
• The tire pressure is shown on the tire pressure labe l. The tire
pressur e lab el is located on the driv er's sid e B-pillar (visible when
the door is open). The tire pressure label l ists the recommended
cold tir e inflation pr essur es for the vehic le at its maximum capacity
weigh t and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for norma l load
conditions, please see chapter~
page 242.
• The tire pressure monitoring syst em he lps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the cor rect tire pressure .•
