The instrument illumination for the needles
and dia ls turns on when the ignition is turned
on and the lights are turned off. The illumina­
tion for the gauges reduces automat ica lly and
eventually turns off as brightness outside in­
creases . T his function reminds the drive r to
turn the low beams on at the approp riate
time.

on. To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold ran ge
If the needle is at the bottom of the gauge, the
engine has not reached operating temperature
yet. Avoid high eng ine speeds, full accelerating
and heavy engine loads.
Normal range
The engine has reached operating temperature
when the needle moves into the center of the
gauge under norma l driving condit ions. The nee­
dle may move farther to the right on the gauge
with heavier engine load at hig h outside temper ­
atu res . If the needle is far ove r on the r ight side
of the gauge and the. in dicator light turns on
i n the instrument cluster, then the coolant tem­
peratu re is too high

- The front spoiler also he lps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the engine speed is below 1,SOO RPM . The begin­
ning of the red zone in the tachometer indicates
the maximum permissible engine speed for all
gears once the engine has been broken in and
when it is warmed up to operating temperat ure.
Before reaching the red zone, you shou ld shift in­
to the next higher gear, choose the Dor S selec­
tor lever position, or remove your foot from the
accelerator pedal.
CD Note
The needle in the tachometer @Q page 8,
fig. 3 may only be in the red area of the gauge
for a short time or there is a risk of engine
damage.
@ For the sake of the environment
Upshifting ea rly helps you to save fuel and re­
duces operating noise.
Fuel level
The fuel level indicator only operates when the
ignition is switched on.
The

tity of fue l is reached.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section ¢ page 210.
CD Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
Instruments and indicator lights
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheat ing and damage
to the catalytic converter.

wait for the engine to slow down to idle
before selecting Dor S.
- If there is a power failure, the selector lever
will not move out of the P position. The
emergency release can be used if this hap­
pens
¢ page 72.
Driving tips
Starting the engine
~ The selector lever must be in the P or the N po ­
sition.
Starting from a stop
~ Press and hold the brake pedal.
~ Press and hold the lock button in the selector
lever handle, select the desired selector lever
position such as D ¢
page 67 and release the
lock button.
~ Wait a moment until the transmission shifts .
You will notice a slight movement when the gear engages .
~ Release the brake pedal and press the accelera-
tor pedal ¢,&. .
Various convenience functions are available for
starting on hills
¢ page 65 .
Stopping temporarily
~ Press the brake pedal to stop the vehicle, for
example at a traffic light. Do not press the ac­
celerator pedal when doing this .
~ To prevent the vehicle from rolling when you
start driving, set the parking brake when stop­
ping on steep hills ¢
8. and ¢0.
~ The parking brake will release automatically
and the vehicle will start moving once you press
the accelerator pedal.
Stopping/parking
If the selector lever is not in the P position when
you open the driver's door, the vehicle could roll.
In vehicles with a convenience key*, the message
Shift to P and turn off ignition, or vehicle can
roll away
appears.
~ Press and hold the brake pedal¢,&. .
~ Set the parking brake .
~ Select the P selector lever position .
Driving
Under certain circumstances, (such as driving in
the mountains or towing a trailer), it may be use­
ful to switch temporarily to the manual shift pro­
gram in order to adjust the gears to the driving
conditions by hand
¢page 70.
On inclines, activate the parking brake first and
then move the selector lever to the P position
¢
page 64. This prevents the locking mechanism
from being loaded too heavily and will make it
easier to move the selector lever out of the P po ­
sition.
A WARNING
= -- The vehicle can roll even when the engine is
switched off.
- Unintended vehicle movement can lead to
serious injuries .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake in all selector
lever positions (except P) when the engine is
running.
- Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged. Otherwise the risk of an accident
increases because the vehicle will start to
move immediately, even if the parking brake
is set.
- To reduce the risk of an accident, do not
press the accelerator pedal when changing
the selector lever position while the vehicle
is stationary and the engine is running.
- Never engage the R or P selector level posi­
tions while driving. It could cause a crash.
- Before driving down a steep slope, reduce your speed and shift into a lower gear in tip­tronic mode.
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and substantially ..,.

Driving
reduces braking performance, increases
braking distance or causes complete failure
of the brake system.
- If you must stop on an incline, always hold
the vehicle in place with the foot brake or
parking brake to prevent it from rolling
back.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload . The . indicator light turns on
and a message appears~
page 71 when
the clutch is overloaded.
- Read and following all WARNINGS
9 &, .
(D Note
-When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­ lected . This can cause the automatic trans­
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped while the selector lever is in the
N position will damage the automatic trans­
mission, because it is not lubricated under
those circumstances ~
page 205, Towing
with a tow truck.
- The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions su ch as frequent starts, creeping for a
long time, or stop-and-go traffic. If the.
indicator light turns on, stop the vehicle at
the next opportunity and let the transmis­
sion cool down
~ page 71.
H ill descent contr ol
The hill descent control system assists the driver
when driving down hills .
Hill descent contro l is activated when the selec­
tor lever is in the Dor S position and you press
the brake pedal. The transmission automatically
selects a gear that is suitable for the hill. Hill de­
scent control tries to maintain the speed ach­
ieve d at the time of braking, within physical and
70
technical limitations. If may still be necessary to
adjust the speed with the brake pedal.
Hill descent control switches off once the hill lev­
els out or you press the accelerator pedal.
&_ WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes .
Manual shifting (tiptronic mode }
The tiptronic mode allows the driver to shi~ the
gears manually .

To keep shifting using the shift paddles, move
the selector lever to the right out of the D/S posi­
tion into the tiptronic shift gate.
Description
The transmission automatically shifts up or down before critical engine speed is reached.
The transmission only allows manual shifting
when the engine speed is within the permitted
range.
Kick-down
Kick-down enables maximum acceleration .
When you press the accelerator pedal down be­
yond the resistance point (called kick-down), the
automatic transmission downshifts into a lower
gear, depending on vehicle speed and engine
RPM.
It shifts up into the next higher gear once
the maximum specified engine RPM is reached .
A WARNING ,~
Please note that the wheels could spin on
slick or slippery roads when kick-down is ac­
tive.

Driving
Emergency mode
Applies to: vehicles with automatic transmissions
In the event of a system malfunction, there is an
emergency program .
If all of the selector lever positions are highlight­
ed with a light background in the instrument
cluster display, there is a system malfunction and
the S tronic transmission is running in the emer­
gency program . The vehicle can still be driven in
emergency mode, but only with reduced speed
and not in all gears . In some cases, the vehicle
cannot drive in reverse.
([) Note
If the transmission runs in emergency mode,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to have
the malfunction corrected.

and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
- The cooling system is under pressure . Do
not open the coolant expansion tank cap
when the engine is hot . This increases the
risk of burns .
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
CD Note
-
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine.
If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.
