outside temperature will appear in the disp lay only after you have
moved the selector lever into a gear (for example, when you shift
into
" D ") .
The snowflake symbo l a lso appears when the outside temperature
is between 41 °F (+5 °C) and 23 °F (-5 °Cl. Th is is to warn you, the
driver, to be extra cautious because the road surfaces may be
i c y . If
the vehicle is at a standstill, or if you are driving at a very low speed, the temperature shown in the display might be slightly higher than
the actua l outs ide temperature. This is caused by the heat be ing
radiated from the engine.
Remember , if your vehicle is equipped with a ir conditioning and you
change the display from °F (Fahrenhei t) to °C (Centigrade), then the
outside temperature will automatically be displayed in

Driver information display
Engine oil pressure malfunction 9=7-
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to inflict severe damage to the engine.
If the ~ symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also
be displayed by pressing the [CHECK] button:
Switch off engine and check oil level
Immediate actions
- Pull off the road.
- Stop the vehicle.
Turn off the engine.
- Check the engine oil level with the dipstick=> page 254.
Dipstick readings checks too low
-Top off oil to the proper level => page 255 .
- Make sure that the oil pressure warning symbol
~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the oil pressure warning symbol~ starts flashing
again even though the engine oil level checks
OK on the
dipstick,
do not continue driving and do not let the
engine run in idle.
Instead, contact your authorized Audi
dealer for assistance.
[ i ] Tips
• The engine oil pressure symbol 'l::::r. is not an indicator for a low
engine oil level. Do not rely on it. Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip .
• The yellow oil level warning indication -requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning
'l::::r. starts to flash before you respond to the low oil
level warning . By then, your engine may already have suffered
serious damage. •

Tire pressure monitoring system
App lies to vehicles: with tire pressu re mon itoring system
General notes C.. ~
Each tire, including the spare (if provided), should be checked
month ly when cold and inflated to the inflat ion pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inf lation pressure label. ( If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pres ­
sure label, you should determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
Controls and equip ­

pressure telltale when one or more of your tires is significant ly
under -inflated. Accord ingly, when the low tire pressure tel ltale illu ­
minates, you shou ld stop and check your tires as soon as possible,
and inflate them to the proper pressure . Driving on a significan tly
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 vehic le's handling and stopping ability .
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibility to maintain correct t ire
pressure, even if under -inflation has not reached the leve l to trigger
il lumination of the TPMS low tire pressure te lltale .
Your veh ic le has a lso been equipped w ith a TPMS malfunction indi­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low tire p ressure
telltale . When the system detects a malfunction, the telltale wil l
flash for approx imately one minute and then remain cont inuously
il luminated . This sequence will continue upon subsequent vehicle
start -ups as long as the malfu nction 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
insta llation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning prope rly . A lways
check the TPMS malfunction telltale after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function
p roper ly .•
App lies to ve hic les : with tire pressu re mon ito ring system
Introduction
The tire pressure m onitoring system monit ors air pressure
in all four road wheels while t he vehicle is moving.
As soon as the tire pressure monitoring system senses a significant
loss of air pressure in one or seve ra l tires, text messages and yellow
~

Driver information display
symbols appear in the instrument cluster display to alert the driver.
The warning light in the instrument cluster comes on when the
tire is significantly underinflated .
The warning light _, also lights up during a system failure.
When the wheel is turning, the system receives radio signals from
sensors located inside each tire .
A factory spare wheel is delivered with sensor. However, the spare
wheel is not checked by the tire pressure monitoring system. Such monitoring can only occur after the spare wheel has been installed
and initialized ~
page 45.
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
vehicle is moving and tire pressure rises. So you should adjust tire
pressure only when they are
cold, when tire temperature is roughly
the same as ambient air temperature.
In order to keep the tire pressure monitoring system properly cali­
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 43.
The tire pressure is shown on the tire pressure label. On USA vehi ­
cles, the tire pressure label 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 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 277.
& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly under -inflated. You should
stop and check your tires as soon as possible, and inflate them to
& WARNING (continued)
the proper pressure as indicated on the vehicle's tire pressure
label
~ page 271. Driving on a significantly under-inflated tire
causes the tire 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 pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
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 monthly when cold and set to the
recommended inflation pressure as specified on the tire pressure
table~
page 277 .
• The tire pressure monitoring system helps the driver to keep
track of the tire pressures . But the driver still 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 must not be
detached or exchanged. Only the valve core needs to be replaced
and, if 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 pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dealer. .,
