A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiation .
- Never turn off the eng ine unti l the vehi­
cle has come to a complete stop .
- The brake booster and power steer ing
only work when the engine is running . If
the engine is off, you have to use more
force when steering or braking. Because
you cannot stee r and brake as you usua l­
ly wou ld, this could lead to crashes and
serious injur ies.
- Avoid high engine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating temperature - ot her­
wise yo u risk eng ine dam age.
- The eng ine cannot be started by pushing
or tow ing the veh icle.
(D Tips
- After a cold engine is started, there may
be a brief period of increased noise be ­
cause oil press ure must fi rst bu ild up in
the hydraulic valve adjusters. This is nor ­
mal and not a ca use for concern .
-If yo u leave the vehicle with the ignit ion
switched on, the ignition will switch off

-You can apply the parking bra ke at any
time -even w ith the ignition swi tched
off . The ignit ion must be on and the
brake pedal must be pressed in order to
release the parking brake .
- Occas iona l noises when the parking
brake is applied and released are norma l
and are not a cause for concern .
- When the vehicle is parked, the parking
brake goes through a se lf-test cycle at
regular intervals. Any assoc iated no ises
a re no rma l.
Parking
• Press the b ra ke peda l to stop the vehicle .
• Pull the swit ch(®) to set t he parking br ake.
• Move the se lecto r lever to P.
• Turn the eng ine off ~&, .
"' When on incl in es or declines, turn the steer­
ing wheel so that yo ur vehicle will roll into
the curb if it begins to move.
A WARNING
- When you leave your veh icle -even if on ­
ly b riefly -always take the ignition key
with you. This applies partic ularly when
c hildren remain in the ve hicle. Otherw ise
t h e c hild ren could start t he engine, re­
lease the pa rking brake or ope rate e lec ­
t rical equipment (e .g. power windows).
The re is the risk of an accident .
- When the vehicle is loc ked, no one -par ­
t icu larly not c hildren sho uld remain in
the vehicle . Loc ked doors make it more
difficult for emergency workers to get in­
to the vehicle -putt ing lives at risk.
Starting from rest
The starting assist function ensures that the
parking brake is released automatically upon
star ting.
Stopping and applying park ing brake

Starting and automatically releasing the parking brake
"' When you start to drive as usual , the park ­
ing brake is a utomat ically released and your
veh icle beg ins to move.
When stopping at a traffic signal or stopping in city t raffic, the par king b rake can be ap­
plied . The vehicle does not have to be he ld
with the footbra ke . The p arking brake elimi­
nates the tende ncy to creep w ith a dr ive range

the pa rking brake is re leased automatically
and the vehicle s tarts to move.
Sta rting on slopes
When starting on inclines , the star ting assist
prevents the vehicle from u nintent ionally roll ­
ing back . The brak ing force of the parki ng
brake is not re leased unti l suff ic ient d riving

(D Tips
Fo r safe ty reaso ns, the pa rking brak e is re­
l eased automatically on ly when t he d riv­
er's safety bel t is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
"' Keep the sw itch(®) pulled and depress the
accelerator . The pa rking brake stays applied
and prevents the v ehicl e from roll ing bac k­
wa rd .
"' Yo u can rele a se the swit ch(®) once yo u are
sure t hat you are developing enoug h for ­
ward momentum at the whee ls as you de­
press the acce lerator .
Depend ing on the we igh t of the rig (vehi cle
and t railer) and the severity of the incline, yo u
may ro ll backwards as yo u start . You can p re ­
vent rolling backwa rds by holding the park ing
brake switch (®) pulled o ut and accelerating -
just as you would when starting on a hill with a conventiona l hand brake .

11-As soon as you release the sw itch C®) or ac-
celerate, the braki ng p rocess stops.
If you pull the sw itch (®) and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking function is in itiated. The v ehicle is
b ra ked at a ll four wheels by activating the hy­
d raul ic br ake system. The b ra ke performance

erator pedal is dep ressed, emergency braking
stops .
.&_ WARNING
Emergency braking shou ld only be used in
an eme rgency, when the normal foot brake
has failed or the brake pedal is obstructed.
Using t he parking brake to perform emer­
gency braking will slow you r vehicle down
as if you had made a fu ll brake applicat ion.

- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traff ic, on twisting roads and
when road conditions are poor (such as
ice, fog, grave l, heavy rain and hydro­
planing) -risk of acc ident .
- Turn off the cruise control temporari ly
when entering turn lanes, highway exit lanes or in const ruction zones .
- Please note that inadvertent ly "rest ing"
yo ur foot on the accelerato r peda l causes
the cruise control not to brake. This is
because t he cr uise con trol is overr idden
by the driver's a cce le rat ion.
- If a brake system malfunction such as

Audi adaptive cruise control and braking guard 91
When approaching a moving vehicl e up ahead,
the adaptive cruise contro l system automati­
cally brakes to match that object's speed and
then maintains the stored distance.
If the ve­
hicle ahead accelerates, adaptive cruise con­
trol will also accelerate up to the stored
speed .
The higher the speed, the greater the distance
in yards (meters) ¢.&. . The
Distance 3 setting
is recommended .
The distances prov ided are specified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
distance may be more or less than these tar ­
get distances.
The various symbols for the time increments appear briefly in the information line @

tings .

A WARNING
Following other vehicles too closely in­
creases the risk of collisions and serious
personal injur y.
- 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 obey applicable traffic laws, use
good judgment, and select a safe follow­
ing d istance for the traff ic, road and
weather conditions .
(D Tips
-Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically
stored and assigned to the remote con­
trol key being used.

In certain situations, the system will prompt
you to take action . This could happen, for ex­
amp le, if braking by the adaptive cruise con­
trol system is not enough to maintain enough
distance to the vehicle ahead .
