After a cold engine is started, there may be a
brief period of increased noise because oil
pressure must first build up in the hydrau lic
valve adjusters . This is norma l and not a cause
for concern .
.&_ WARNING
-
-Never allow the engine to run in confined
spaces -danger of asphyxiation.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- Always take the key with you whenever
you leave your veh icle . Otherw ise, the
engine could be started or electrical
equ ipment such as the power windows
could be operated . This can lead to seri­
ous injury .
- Never leave children or persons requiring
assistance unattended in the vehicle . The
doors can be locked using the remote
tr an smitter, preventing people from es­
caping from the veh icle on their own in
the event of an emergency. Depending
on the time of year, peop le inside the ve­
hicle can be exposed to very high or very
low temperatures .
(D Note
-Avo id high engine rpm, full throttle and
heavy eng ine loads until the engine has
reached operating temperature -other­
wise you risk engine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions .

.. Manual transmission: Shift into 1st gear.
.. When on inclines or declines, turn the steer­
ing wheel so that the vehicle will roll into
the curb if i t beg ins to move.
A WARNING
--- When you leave your vehicle -even if on-
ly briefly -always remove the ignition
key . Thi s app lies pa rticula rly whe n chil­
dren remain in the vehicle. Ot herwise t he
children could star t the eng ine , release
the par king brake or operate electrical
equipment (e.g. power windows). There
is the risk of an accident.
- When the veh icle is locked, no one -par­
ticularly not children should remain in
the vehicle . Locked doors make it more
difficult for emergency workers to get in­
to the vehicle -putting lives at risk .
Starting from rest
The starting assist function ensures that the
parking brak e is r ele ased automatically upon
star ting.

78 On the road
Startin g and automati cally r ele a s ing the
p ark ing b rake
.. When you start to drive as usua l, the park ­
ing brake is automatically re leased and your
vehicle begins to move.
When stopping at a traffic signa l or stopping
in city traffic on vehicles with an automatic
transmission, the park ing brake can be ap­
plied. The vehicle does not have to be held
with the footbrake. The park ing brake elimi­
nates the tendency to creep with a drive range
engaged . As soon as you dr ive off as usual,
the park ing brake is released automatically
and the veh icle starts to move .
Starting on sl opes
When starting on incline s, the start ing ass ist
prevents the vehicle from unintentionally roll­
ing back. The braking force of the parking
b rake is not released until sufficient dr iving
fo rce has been bu ilt up at the whee ls.
(D Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er 's sa fety belt is engaged in the bu ck le.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch@¢ page 76, fig. 78 pulled
and depress the acce le rator . The park ing
brake stays applied and prevents the vehicle
from roll ing backward.
.. You can release the switch @once you are
sure that yo u are developing enough driving
force at the wheels by depressing the accel ­
erator.
Depending on the weight o f the rig (vehicle
and trai ler) and the severity of the incline, you
may roll backwards as you start . Yo u can pre­
vent roll ing backwards by holding the parking
brake switch @pulled out and accelerating -
just as you would when starting on a hill with a conventional hand brake . Emergency braking
In the event that the conventional brake sys­
tem fails or locks .
.. In an emergency, pull the switch @
¢
page 76, fig. 78 and continue to pull it to
slow your vehicle down with the parking brake .
.. As soon as you re lease the switch @ or ac-
celerate, t he b ra ki ng pro cess stops.
If you pull the switch @and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy bra king funct ion is initiated . Th e ve hicl e is
braked at all fou r whee ls by activating the hy­
draulic brake sys tem. The brake performance
is similar to making an emergency stop¢,& .
In order not to a ct ivate the eme rgency brak­
ing by mis take, an audib le warning tone (buz­
zer) so unds when the switch @is pulled. As
soon as the switch @ is released, or the acce l­
erator pedal is depressed, emergency braking
stops.
A WARNING ,-
Emergency braking should only be used in
an emergency, when the normal foot brake has fa iled or the brake pedal is obstructed .
Using the par king brake to pe rform eme r­
gency b raking will s low your veh icle down
as if you had made a full brake application.
The laws of phys ics cannot be suspended
even with ESC and its associated compo ­
nents (ABS, ASR, EDS) . In corners and
when road or weathe r cond itions are bad,
a full brake application can ca use the vehi ­
cle to sk id or the rear end to break away­
risking an accident.
Speed warning system

Warning threshold 2 can be set in the speed range starting from
20 mph to 150 mph (30
km/h to 240 km/h). Settings can each be ad­
justed in intervals of
6 mph (10 km/h).
Cruise control
Switching on
The cruise control system makes it possible to
drive at a constant speed starting at
20 mph
(30 km/h).

shown in the display¢
fig. 81. The display
may vary, depending on the type of display in
your vehicle.
The speed is kept constant by modifying en­
g ine power or through an active brake inter­
vention.
A WARNING
-- Always pay attent ion to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your veh icle and other vehicles.
- For reasons of safety, cruise control
should not be used in t he city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
p laning) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "resting"
your foot on the accelerator pedal causes the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be sw itched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models)/ ... (Canadian models)
is on.
(D Tips
-Veh icles with manual transmiss ion: You
can attain the set speed only if the gear
th at is cur rently engaged will allow it, or
if it does not tax the engine and allows it
to run smoothly. Therefore shift into a
hig her or lower gear in a timely manner.
- Th e brake lights illuminate as soon as
the brakes apply automatically.

S tronic, tiptronic
Introduction
Applies to vehicles: with S tronic/tiptronic
T he automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatica lly depending on which drive
program is selected.
When a
moderate driving style is used, the
transmission selects the most economical
driving mode. It will then change up early and
delay the downshifts to give better fuel econ­
omy .
T he transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
ce lerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) c> page 86.
Various automatic transmissions may be in­
stalled, depending on the model:
S tronic transmission
The S tronic is a dual-clutch transmission.
Power is transferred using two clutches that
work independe ntly from one another. Th ey
replace the torque converter used in conven­
tional automatic transmissions and al low the
vehicle to acce lerate without a noticeable in­
terruption in tract ion.
tiptronic transmission
In the tiptronic transmission, power is trans­
f er red by a torque converter.

Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regulating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system .
If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac ­
celerate your vehicle. This he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 96.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them
properly at all times.
General information
