N => &, .
-Turn the ign ition key to position 0 => fig . 14 5 -do not
depress the gas pedal when start ing t he engine .
A cold engine may sound loud after it has be en started. This is due
to the hydrau lic valves building up oil pressure. This is normal and
is not a n eed fo r concern .
I f 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 en clo sed are a.
Exhaust fumes from the engine contain carbon monoxide, a color ­
less and odorle ss gas . Carbon mono xide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended

loads while the engine is still cold. This could damage the engine.
• The eng ine ca nnot be s tarted by push ing or towi ng the ve hicle.
To avoid unnecessary engine wear and to reduce exhaust emis ­
sions, do not let your vehic le stand and warm up. Be ready to drive
off im mediately afte r starting your vehicle . Maintain modera te
speed until the engine is completely warm . Remember , the engine
performs best at operating temperature. •

On the road -----------------
Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.

Controls and equip­ ment
&, WARNING (continued)
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to roll.
• Never allow anyone -especially small children -to remain
in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs . Parking barriers and curbs vary in
height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too high, as you park or as you back out of a parking spot. In order to be
sure that no such damage can occur, you may wish to stop short of
having the front tires of your car touch the parking barrier or curb.
• Please also exercise exceptional care when you drive up or down
steep ramps or drive over curbs or other obstacles, for which the
vehicle is not designed , because components of the vehicle close to
the ground, such as bumper covers, spoilers and suspension and
exhaust system components, may become damaged. •

&, WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­
erator pedal causes the cruise control not to brake . This is because
the cruise control is overridden by the driver's acceleration.
[ i] Tips
The brake lights illumin ate as soon as the brakes decelerate
automatically. •
Changing speed
-Press lever@in the 0 or Q direction=> page 137,
fig. 149 to increase or decrease your speed.
-Release the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing
the lever . If you keep the lever pressed down, you will alter your
speed in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your
speed, e.g. if you want to pass someone. The speed you saved
earlier will resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily.
The green symbol in the
display=> page 137, fig . 150 is replaced
with a white symbol. The saved speed remains the same. •
Presetting your speed
You can preset your desired speed while the vehicle is not
moving.
-Turn on the ignition .
-Pull lever@ into position G) => page 137, fig. 149 .
-Press the lever in the 0 or Q direction to increase or
decrease your speed.

[ i] Tips
• For sa fety reasons, the stored speed is deleted when the ign it ion
is turned off .
• When Adaptive Cru ise Control is switched on, the Electronic
Stabilization Program (ESP) is also automatically activated.
• Damage caused by accidents (e.g . if the vehic le is damaged
when parking) can affect the radar sensor settings. This can cause
the system to malfunct ion or switch off completely.
• In winter conditions, you should check the radar sensor cover
before driving to make sure it is free of ice and snow. If necessary ,
clean the area near the radar sensor
carefully => page 139, fig. 151.
• To ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, larger license plate mounts, add -on parts) must not
cover the area near the radar
sensor=> page 139, fig . 151. The area
near the radar sensor must not be painted, either .•

How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of the
radar sensor.
Fi g. 152 Ra dar sens or
me asuremen t range
A forward -look ing radar sens or in the fro nt b umper monitors the
traffic situation ahead . Vehicles moving in your direction can be
de tec ted up to a distance of a bout 140 yards ( 130 meters) but the
Adaptive Cruise Contro l cannot detect vehicles that are stopped or
stal led, obstac les that do not move or narrow vehic les like motorcy ­
cles and
bicycles.=> fig. 152 .
Open road
When the road is clear, Adaptive Cruise Contro l works like cruise
co ntrol. The stored speed requested is main tained .
Driving in tr affi c
If you start to catch up with a vehic le in front of you, Adap tive Cruise
Control automatically slows your vehic le to a speed that will he lp
you stay a safe distance back .
If the vehicle in front acce lerates, Adaptive Cruise Control a lso accel -
erates up to the speed that you have set . .,_

& WARNING
Improper use of the Ad apti ve C ruise Control can caus e colli sio ns,
other a ccident s and seri ou s per sona l injurie s. Never re sume the
s to red sp ee d if th e speed i s to o high for pr evailin g road , traff ic or

Reducing distanc e
Push the slider switch once toward Q . The dista nce
current ly set is shown f or 3 seconds in the instrument
cluster d isp lay .
P u sh the s lider switch
again towar d Q, to decrease the
dist ance by one step.
The distance at which Adaptive Cruise Contro l fo llows a vehicle in
front is determined by
time in tervals. A time interval is established
which is mainta ined to a vehicle in front . This produces a speed ­
dependen t interval. The higher the speed , the greater the safe ty
interval in yards (meters) .
For example , if the interval
DIST AN CE 3 is set , a vehicle in front is
followed at a
time interval of 1.8 seconds .
• For a speed of
55 mph th is would be equiva lent to a distance of
4 8 y ard s to the vehic le in front .
• For a speed of
100 km /h this would be equivalent to a distance
of
5 0 m eter s to the vehicle in front. _.

& WARNING
• The rear-view camera has blind spots , in whi ch objects cannot
be detected. Be especially careful to check for small children and
an imals before ba ck ing up . Small children and animals will not
always be detected by the sensors.
• The Audi parking system is not a substitute for being careful
and alert when backing up. Be especially careful during parking
and similar maneu vers . Always watch where you are driving and
make sure that nothing is in the way .
• Remember that low obsta cles which have already been
signaled may pass below the system's sensing zone when the
vehicle is ba cking up . The fact that the signal stops does not mean
that you have cleared the obstacle . When the signal stops , impact
is imminent . Objects such as trailer hit ches , 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 warning .
• Always make sure that the volume and frequency of the chimes
is adjusted so that you can easily hear the acoustic distance signal
even if the radio is playing, the air -conditioner blower is on High or
there is a high level of outside noise .
- Check the settings whenever someone else has driven the
vehicle before you.
• Improper reliance on the Audi parking system can cause colli­
sions and serious personal injury .
- Never rely only on parking assist when chang ing backing up .
- Always check rear view mirrors to make sure it is safe to back
up .
