Starting and stopping the engine
Starting the engine
The engine can only be started with on original Audi key
and the clutch pedal* depressed.
- Set the parking brake.
Move the selector lever to the neutral position (automatic
transmission: selector lever in P or N)
~ & .
- On vehicles with manual transmission, fully depress the
clutch pedal.
- Turn the ignition key to position
0 ~ page 92, fig. 79 -
do not depress the gas pedal when starting the engine!
- Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure . This normal
and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.

ment
On the road
0 Note
• Avoid high engine speeds, fast acceleration or heavy engine
loads while the engine is still cold. This could damage the engine.
• The engine cannot be started by pushing or towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emis­
sions, do not let your vehicle stand and warm up. Be ready to drive
off immediately after starting your vehicle. Maintain moderate
speed until the engine is completely warm. Remember, the engine
performs best at operating temperature. •
Stopping the engine
-Turn the ignition key to position G) ~ page 92, fig. 79.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up
in the engine
compartment. .,

Selector lever positions
All the selector lever positions are explained in this
section.
Fig. 85 Display:
Selector lever posi ­
tions
The selector lever position is shown in the instrument cluster
display by highlighting the appropriate symbol.
P -Park lock
In this position the gears are mechanically locked.
The park lock must only be engaged with the vehicle
stationary
=>& .
To engage P and to remove the lever from this position, you must
depress the release button (button in the selector lever handle)
and
simultaneously you must step on the brake pedal.
R -reverse
In this position, reverse is engaged. Reverse gear must only be engaged with the vehicle
stationary and
the engine running at idle speed=>& .
To engage R, you have to depress the release button
and simulta­
neously step on the brake pedal. In the R position, the back -up lights
illuminate with the ignition on.
N -Neutral
The transmission is in neutral in this position .
D -Normal position for driving forward
In this position, the forward gears are automatically shifted up and
down, depending on engine load and vehicle speed.
To engage S from N, the brake pedal must be depressed at speeds
below 5 km/h or when the vehicle is stationary=>& .
In certain circumstances (driving in the mountains for example) it
can be beneficial to switch temporarily to the manual shift program
=>
page 103 in order to adjust the gear ratios to driving conditions
manually .
S -Sport setting
Th e S setting should be selected for sporting driving . The power
reserves of the engine can be fully exploited through later upshifts.
To engage S from N, the brake pedal must be depressed at speeds
below 5 km/h or when the vehicle is stationary =>& .
& WARNING
• Never place the selector lever in the R or P position while the
vehicle is moving -risk of an accident!
• With the engine running, it is necessary to hold the vehicle with
the foot brake in all selector lever positions (except P and Nl,
because even at idle speed the transfer of power is never
completely interrupted -the vehicle "creeps".
If the vehicle is
stationary and the transmission is engaged, the engine should
never be speeded up unintentionally (e.g. manually from under the _.,

ment
- With your right foot, step on the accelerator to the wide­
open throttle position or Kickdown. The engine speed
settles at about 3,200 rpm.
- Take your left foot off the brake.
The S tronic® in your vehicle is electronically controlled. A special
Launch Control Program provides the best acceleration from a
standing start .
& WARNING
• Always adapt your driving to the traffic flow.
• Only use Launch Control when road and traffic conditions allow
it and other drivers will not be endangered or annoyed by your
driving and the acceleration of the vehicle.
• Make sure that ESP remains enabled. With the ESP disabled,
the vehicle could brake away, particularly on a slick and slippery road -risk of skidding!
• Once acceleration is finished, switch ASR on again by briefly
pushing the ESP button. •
Applies to vehicles: with S tronic®
Back-up program
In the event of a system malfunction, there is an back-up
program.
In the event of system malfunctions, the automatic transmission
switches to the fail- safe mode. This is signalled by one segment or
all the segments in the display illuminating or going out .
Th e effect of a system malfunction can be one of the following:
• The program shifts only into certain gears.
• Reverse gear can no longer be engaged.
