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. •
Yellow symbols
A yellow symbol means WARNING.

Warm and cold
Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Select and set a temperature between 64 °F (+22 °C) and
86 °F (+29 °C).
- Press the !AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting, as desired, to meet your personal
needs.
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle.
The air temperature, air flow and air distribution are automatically regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
The system automatically compensates for changes in the outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode=> page 112
for year -round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This
also prevent the windows from fogging up. When the outside temperature is high and the air is very
humid,
condensation from the evaporator may drip under the vehicle. This
is normal and does not indicate a leak.
I f the outside temperature is low, the fan normally only switches to
a higher speed once the engine coolant has warmed up sufficiently.
The air conditioner temporarily switches off when you drive off from a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated charcoal filter) reduces or eliminates outside air pollution (dust, or
pollen) from entering the vehicle.
The air pollutants filter must be changed at the intervals specified in your Warranty
& Maintenance booklet, so that the air conditioner
can properly work.
If you drive your vehicle in an area with high air pollution, the filter
may need to be changed more frequently than specified in your
Audi Warranty
& Maintenance booklet. If in doubt, ask your autho­
rized Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
These settings will differ depending if the roof is opened or closed.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.

- Then press the rollover bar all the way down until you
hear it engage.
Check to make sure the rollover bar is securely engaged
before you release your grip on the bar.
Close the cover @~ page

- Perform the same procedure on the second rollover bar.
- You can now open and close the power top again.
& WARNING
• If there is a problem in the rollover protection system, the
system must be checked by a professional mechanic as soon as
possible.
If this is not done, there is a risk that the rollover protec­
tion system may not be activated in the event of an accident.
• No modifications of rollover protection system components
are permitted.
• Work on the rollover protection system must only be done by a
professional mechanic . Improperly performed work can cause the
system to fail or release unintentionally, possibly causing an
injury!
• Always have your vehicle serviced whenever the service
interval display indicates that it is time for service . This will ensure
that the system will operate properly over the long term. The roll­ over protection system must be checked by a professional
mechanic every two years or sooner. •

Braking
General information
What affects braking efficiency?
O pera tin g co ndition s and drivi ng h abit s
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and dr iving habits~
&­
On vehicles that are either driven mostly in stop -and -go city traffic
or are driven hard, the brake pads shou ld be checked by your autho­
rized Audi dealer more often than specified in the
W arr anty & Main ­
t e nanc e bo okle t.
Fai lure to have you r brake pads inspec ted ca n
resu lt in reduced brake performance.
On steep slopes, you shou ld use the braking effect of the engine.
This way, you prevent unnecessary wear on the brake system. If you must use your brakes, do not hold the brakes down continuous ly.
Pump the brakes at intervals.
Moi sture or road salt
If you are driv ing faster than 50 mph (80 km/h) and the windshie ld
wipers are on, the brake pads wi ll briefly touch the brake discs in
regu lar intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, wil l not notice anything.
Under ce rta in conditions, for example, when dr iving through water
or very heavy rain, or even after washing your vehicle, the braking
effect can be reduced due to moisture (or in freezing conditions ice)
on the brake pads. A few cautious brake applications should dry off
the b rake pads or remove any ice coatings .
At speeds
over80 km/h and with the windshie ld wiper turned on, the
brake pads are app lied briefly to the brake discs. This occurs at
regu lar interva ls wi thout the driver not icing and provides for better
brake response time under wet conditions.
The effectiveness of the brakes can be reduced when the vehicle is driven on a sa lt-covered road and the brakes are not used. Likewise,

you clean off accumulated sa lt coating from brake discs and pads
with a few ca utious applications of the brake ~
&-
Cor rosi on
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is not driven regularly or
only f or sho rt trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firm ly a few times from a moderately high speed~
&-
Fa ults in the brake system
If you shou ld notice a sudden increase in brake pedal trave l, then
one of the two brake circuits may have failed~
&-
Lo w brak e fluid l evel
Malfunctions can occur in the brake system i f the brake fluid level is
too low . The brake fluid level is monitored electronically .
Brake lining wear statu s
Brake lining wear may be checked by visua l inspection of the condi ­
tion o f the brake pads through the open ings in the wheel. If neces­
sary, the wheel may be removed for this inspection

Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle.
- Do not warm up the vehicle by letting the engine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings, or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fuel than is burned s tarting the engine again .
It takes a long time for the engine to warm up fully when it is
running at idle. However, wear and noxious emissions are especially
high when the engine is warming up. So you should drive away as
soon as you star t the engine and avoid running at high rpms while
the engine is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended id ling also produces heat, which could
resu lt in overheating or other damage to the veh icle or other
property .•
Regu1ar maintenance
A badly tuned engine unnecessarily wastes a lo t of fuel.
- Have your ve hicle serviced at regular intervals . By having your vehicle regularly serviced by an Audi dealer helps to
ensure that it runs properly and economical
ly . The condit ion of yo ur
vehic le not only affects its safety and abi lity to hold its va lue, it also
affects
fuel consumpt ion .
C heck your oil each time you fill your tank .
The amount of oil used is related to engine load and speed.
I t is norma l for the oil consumption of a new engine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) be fore you can properly assess oil consumption .
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. Lack of proper maintenance as well as improper use of the
vehic le wi ll impai r the function of the em ission control system and
cou ld lead to damage.
• Do no t alter or re move any component of the Emiss ion Contro l
System unless approved by the manufacturer.
• Do not alte r or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
vehic le's Emission Control System and other important veh icle
components. •
