• Please also exercise exceptional care when you drive up or down
steep ramps or drive over curbs or other obstac les, f or which the
vehicle is not designed, because components of the veh ic le close to
the g round, suc h as bumper covers, spoi lers and suspension and
exhaust system components, may become damaged . •
Starting off with a trailer
To p reven t ro lling b ack unintentionally o n an incline, do
the foll owing:
- Keep the sw it c h pulled and depr ess the acce lera to r. The
p arking b rake stays a pplie d a nd pre ve nts the v ehi cle
f rom rolling backw ard .
- You can rele ase the switch o nce you are sure t hat you are
deve lo p ing e noug h forward mo mentum at the whee ls as
yo u de press the accelera tor.
Depending on the weight of the rig (vehicle a nd trailer) and the
severity of the inc line, you may roll backwards as you start. You can
prevent rolling bac kwards by holding the parking brake switch
pul led out and acce lerating -just as you would when starting on a
hill with a conven tiona l hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks .
-Pull the sw itch and cont inue to pu ll it to slow yo ur vehicle
with the parking b rake in an emergency.
- As soo n as you release the sw itch or acce le rat e, the
b raking proc ess s tops .
Controls and equip
ment
I f you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initia ted . The ve hic le is
braked at all four whee ls by activating the hydraulic brake system.
Brake performance is sim ilar to mak ing an eme rgency stop=>& .
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled. As soon as
t he sw itch is released, or the accelera tor pedal is depressed, emer
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency , when
the normal foot brake ha s failed or the brake pedal i s obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle as if you had made a full brake application. The law s
of physi cs cannot be suspended even with E SP and its asso ciated
components (ABS , ASR , EDS ). In corner s and when road or
we ather conditions are bad , a full bra ke appl ication can cau se the
vehicle to skid or the rear end to break away -risking an
accident .•

Adaptive Cruise Control
Speed and distance control system
Applies to vehic les : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance program is
a combined speed and distance control system.
Fig. 129 Front
bumper: Position of
radar sensor
Any speed between about 20 mph (30 km/h) and about 95 mph
(150 km/h) can be set and he ld with the Adaptive Cruise Con trol. The
system also regulates a pre-set distance from the vehicle ahead
within the limits of the system described.
Driving can be more relaxed, particularly on long trips on interstates
or on other highways that are generally straight.
How does it work?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column::::> page 137, "How is the speed stored?" and
=> page 140, "How is the distance (time interval) set?".
Con tro ls and eq uip
ment
Driver information
Important information is brought up in the speedometer and in the
instrument cluster display as the vehicle is being driven
=> page 142, "Driver information" .
What is important for you to know
The Adaptive Cruise Control is set with system -specified limits, that
is, as a driver, you will have to adjust the speed and distance to the
vehic le ahead in some instances=> page 146, "Driver intervention
prompt" and=> page 147, "System limita tions".
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury .
• Never drive at speeds that are too high for traffic , road and
weather conditions.
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safely. The Adaptive Cruise Control cannot brake the
vehicle safely when you follow another vehicle too closely. Always
remember that the Adaptive Cruise Control has a braking power
that is only about 25% of the vehicle's maximum braking ability,
the automatic braking function cannot bring the vehicle to a stop.
• Never use Adaptive Cruise Control on roads where you cannot
drive safely at a steady speed, including city, stop-and-go or heavy
traffic, on winding roads or when road conditions are poor (for
example, on ice, gravel , in fog , heavy rain or on wet roads that
increase the risk of hydroplaning).
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray. This can result in vehicles driving ahead being inade
quately detected or, in some circumstances, not detected at all. If
necessary , take action yourself! ._

How is the distance (time interval) set?
Distance can be set in four stages.

Increasing distance
- Pus h the slid er switch once to the r ig ht G) ::::;> fig. 135. The
dista nce currently set is shown for 3 seconds in the

Push the s lid er sw itch

Reducing distance
Push th e sli de r sw itch once to the left Q. The distance
current ly set is shown for 3 seconds in the instrument
cluster disp lay.
- Pu sh the s lider swi tch
again to the left Q to dec rease t he
dista nce by one step.
The distance at which the Adap tive Cruise Control follows a vehicle
in front is determ ined by
time intervals. A time interva l to a vehicle
in front is estab lished and mai nta ined . This produces a speed
dependent interval. The higher the speed , the greater the safety
interval in yards (meters)~& .
For example, i f the interval
DISTANCE 3 is set, a vehicle in front is
followed at a
t i me interval of 1.8 seconds .
Fo r a speed of
55 mph (100 km /h ) this would be equiva lent to a
distance of
4 8 yard s (50 mete rs ) to the vehicle in front.
The distances given here are specified values. The vehicle speed may exceed or fa ll shor t of these target speeds, depending on the
driving situation and the driving sty le of the v ehicle ahead.

& WARNING (continued)
• Setting short distances to the traffic ahead reduces the time
and distance available to bring your vehicle to a safe stop and
makes it even more necessary to pay close attention to traffic.
• Always use good judgment and select a safe following distance
for the traffic, road and weather conditions.
[ i ] Tips
The distance setting is reset to the factory default DISTANCE 3 the
next time the ignition is turned on.•

Audi lane assist
Lane assist
Applies to vehic les : w ith lane assist
Description
Lane assist helps you keep your vehicle in your lane.
Lane assist uses a camera to detect lane boundary lines. If the
system detects that your vehicle is about to leave a lane boundary
line, the steering wheel
vibrates to alert the driver . If lane assist
de tects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indicator light /: on the instrument cluster.
If the system is in active standby mode and the turn signal is acti
vated before driving over the boundary line, the warning does not
occur since the system allows for intentional lane changes.
The system is designed for driving on freeways and expanded high
ways and thus works only at speeds of 40 mph (65 km/h) or more.
& WARNING
• Lane assist will not keep your vehicle in your lane. The system
only warns the driver when the vehicle is leaving the lane . The
driver is always responsible for keeping the vehicle in the lane .
• The camera is not able to detect all lane boundary lines and in
some cases might also detect lane structures or objects as
boundary lines . This can lead to incorrect warnings or warnings
that fail to go off at all.
• The camera's visibility can be impaired by vehicles ahead of
you , for instance, or by rain, snow, heavy spray or light shining into
the camera lens. This can cause lane assist to fail to detect
boundary lines. •
