Starting and stopping the engine
Starting the engine
The engine can only be started with your original Audi
key.
- 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 119, fig. 136
- 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.
What to do if the engine does not start
• ~ page 304, "Starting with jumper cables"
• ~ page 306, "Emergency towing with commercial tow truck".
& 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.
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 (D => page 119, fig. 136.
& 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. _,.

Acoustic park assist
A pplies to vehicles : with 4 -ch an nel a co ustic park ass is t
Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car.
How it works
The acoustic park assist warning system (4-channel acoustic park
assist) uses ultr asonic sensors to warn yo u when you are
backing
your vehicle close to an obstacle . The system 's 4 sensors are located
inside the rear bumper .
Acti va ting
The rear acoustic park assist is ac tivated whenever you shift into
Reverse . You will hear a warn ing tone when the system is on .
Reverse
With the car backing up in reverse gear, the col lision warning sound
sets in at the fol lowing
approximate d istances to obstacles :
straight aft 5ft(1.5m)
angling aft off vehicle corners 2 ft (0
.6 m)
As the dis tance shr inks, the time interva l between the audible tones
grows shorter.
The sound changes to a continuous tone as soon as the remaining distance to an obstacle closes to less than about 1 ft. (0 .3 ml. The
steady tone cautions you that you have backed up hazardously
close and you ris k co llision by backing up any further .
Malfunctions in the system
If a warning tone is audible for about five seconds when you turn on
the ignit ion, there is a malfunction in the system . Have the prob lem
corrected by your authorized Audi dea ler. _,.

On the road ------------------------------.J
Keep the sensors in the rear bumper clean and free from ice so that
the acoustic park assist system can function properly.
& WARNING
• Sensors have dead spaces in which objects cannot be
detected . Be especially alert for small children and animals, since
they are not always detected by the sensors.
• The acoustic park assist system is not a substitute for the
driver's own caution and alertness. Ultimate responsibility always
remains with the driver during parking and similar maneuvers .
Always watch where you are driving.
0 Note
• Remember that low obstacles for which a warning has already
been issued may "dive" below the system's sensing zone if the
vehicle is being backed up closer. In this case, the warning sound
shutting off does
not indicate that you have cleared the obstacle .
Instead, impact is imminent.
• Objects such as trailer hitches, barrier chains, narrow posts or
fences covered by a thin layer of paint may not always be detected
by the system . They can still damage your vehicle without a
warning.
[ i] Tips
Keep the sensors in the rear bumper clean and free of snow and ice
so that the acoustic parking assist system can function properly. •

Cruise control
General information
The cruise control system allows you to maintain a
constant speed.
The cruise control system allows you to maintain a constant driving
speed when driving faster than 18 mph (30 km/h) -to the extent this
is possible with the given engine power and braking characteristics .
This allows you to take your foot off the "gas" and rest it, especially
on long trips.
The indicator light (U.S. models :
CRUISE , Canadian models:•(') ) in the
instrument cluster illuminates when the system is on.
& WARNING
• To help keep the vehicle under control, do not use the cruise
control system when driving on winding or slippery roads (as
caused by heavy rain or loose gravel on the road surface), or in
heavy or varying traffic.
• Only use the cruise control when traffic, road and weather
conditions allow you to drive at a steady speed.
[ i] Tips
The cruise control cannot maintain a constant speed when driving
downhill. The vehicle will accelerate under its own weight. Down­
shift to a lower gear or use the brakes to slow down .•

& WARNING
• Unintended vehicle movement can cause serious injury .
- When the selector lever is in a driving position , the vehicle
may creep , even at idle speed . Therefore do not release the
parking brake or foot brake until you are ready to move,
because power is transmitted to the wheels as soon as a
driving position is engaged.
- Do not accelerate while selecting a driving position . At this
time the engine must be at idle speed so that undue stress is
not placed on the clutches in the transmission .
- Remember: -even when stopped briefly with the automatic
transmission in "D ", "S " or "R ", engine power is being trans­
mitted to the wheels. Your vehicle could "creep" forward or
ba ckward . When stopped , keep the brake pedal fully depressed
and use the parking brake if necessary to keep the vehicle from
rolling .
• If the selector lever is unintentionally moved into N while you
are driving , take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving posi ­
tion .
• Never shift into "R " or "P " when the vehicle is in motion .
• Never get out of the driver 's seat when the engine is running .
• If you must get out of the vehicle , move the selector lever
securely into the P pos ition and apply the parking brake firmly .
• If the engine must remain running , never have any dr iving posi ­
