Trip computer
Introduction
The trip computer gives you inf ormation on current and
average fuel mileage, average speed, fuel range and
driving time .

mi lea ge
You can switch between the trip computer 1 and 2 by pressing the
Reset button
@ ~ page 40 , fig. 27
You can tell which memory level is currently active by the number in
the display ~ fig . 26 . The data from the single -trip memory
(memory level 1) is being disp layed if a
1 appears in the display. If a
2 is shown, then the data from the total -trip memory is being
displayed (memory leve l 2) .
Sin gle -trip mem ory (Trip compute r 1)
The single -t r ip memory stores the trip information from the time the
ignition is turned on until it is turned off. If the trip is continued
within 2 hour s from the time the ignition was turned off, the new
data wi ll be included in the calcu lation of the current trip informa ­
tion. If the trip is interrup ted for
more than 2 hour s the memory is
reset automatica lly. _,.

and navigation information can be displayed. To switch the display
between the different systems, tap the Reset button
@ briefly .
You can reset the following va lues to zero using the reset button:
• driving time
• average mileage

In addition,
a ll the values in the single -trip or the total-trip memory
can be de leted simu ltaneously .
[ i ] Tips
• If you hold down the reset button for longer than 2 seconds, the
current value (for example, average fuel consumption) will be reset

Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significant ly
under -inflated. The TPMS only provides a low tire pressure warning
and does not reinflate your tires.
Accordingly, when the low tire pressure tellta le illuminates, you
should stop and check your tires as soon as possib le, and inflate
them to the proper pressure. Driving on a significantly under­
inflated t ire causes the tire to overheat and can lead to tire failure .
Under -inflation a lso reduces fuel efficiency and tire tread l ife, and
may affect the vehicle's handling and stopping ability.
(D Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's respons ib ility to maintain correct
tire pressure, even if under -inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale .
• Each tire, including the spare, should be checked monthly when
cold and inflated to the inflat ion pressure recommended by the
vehic le manufacturer on the vehicle p lacard or tire inflation pres ­
s u re label. (If your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure labe l, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehic le has a lso been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating proper ly . The
TPMS malfunction indicator is combined with the low tire pressure _.,

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 .•
Wheel change
If a wh eel is ch anged , the wheels tha t were exchan ged
have to be re -programmed.
- Tu rn on the ignition.
- Press the button :::> fig. 29 for approximately 5 seconds .
You will hear a beep and the symbol in the button flashes
three times.
Programming is necessary :
• after the t ires have been rotated on the vehicle, or the spare tire
is used,
• if tires with new wheel sensors are used .
All pressure warning indicators in the disp lay wil l be canceled . The
system malfunction error message will not disapp ear until the .,_

children the opportunity to start the engine and/ or a ctivate vehicle
systems such as the power windows etc . Unsupervised operation
of any vehicle system by children can result in serious injury .

The transmitter and battery are located in the head of the remote
control. The receiver is located inside the vehicle. The maximum
effective range depends on several things. Remember, if the battery
is weak, the effective range decreases.
If you need to replace the remote control, or if you need to have it
repaired, you must see your authorized Audi dealer. Only then can
you use the key again.
[ i ] Tips
• If the ignition is switched on , the remote control system is deac ­
tivated.
• The remote control system can be affected by other systems
operating in the same frequency range close to the vehicle, such as
mobile telephones, television broadcasting stations, etc. •
Check light in remote master key
The check light in the remote master key indicates the
state of charge of the battery.

origina l.•
Electronic immobilizer
The immobilizer helps to prevent unauthorized use of
your vehicle.
A computer chip inside your key automatically deactivates the elec­
tronic immobilizer when you insert the key in the ignition lock.
When you remove the key from the ignition lock, the e lectronic
immobil izer is automatically activated once again.
If an unauthorized key was used, SA FE is displayed continuously in
the odometer display field .
& WARNING
Always ta ke the key with y ou when you le ave the vehi cle. The key

[ i ] Tip s
• Your engine can only be started using the fac tory -equipped key .
• You may not be ab le to start your vehicle if an ignition key of a
different vehicle make is a lso loca ted on your set of keys .•
