you can not maintain this min imum dis­
tan ce, the airbag system cannot protect
yo u properly.
- If p hys ica l limi tations prevent y ou from
sitting 10 in ches (25 cm) o r more from
the steering wheel, check with yo ur au­
tho rized Aud i dealer to see if adaptive
equipment is availab le .
- If the steerin g wheel is aligned wi th you r
face, the supp lemental drive r's airbag

When starting from rest
- The integral start ing assist helps you when
driving by automatically re leasing the park­
ing brake c>
page 80, Starting from rest.
-When start ing on inclines, the starting as­
sist p revents the vehicle from unintentiona l­
ly rolling back. The braking force of the
parking brake is not re leased until sufficient
driving force has been built up at the
wheels.
Emergency brake function
An emergency brake ensures that the vehicle
can be slowed down even if the
normal brakes
fail

80 On the road
& WARNING
-When you leave your vehi cle -even if on­
ly brief ly -always take the ignition key
with yo u. This applies par ticu larly when
children remain in the veh icle. Otherw ise
the ch ildren could start the engine, re­
lease the parking brake or operate elec­
trical equipment (e.g. power windows) .
There is the risk of an accident.
- When the vehicle is locked, no one -par­
t icularly not children should remain in
the vehicle. Loc ked doors make it more
difficult for emergency wor kers 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 starting.
Stopping and applying parking brake
" Pull the switch ID to apply the park ing
brake.
St arting and automa tically relea sing the
parking brake
.. When you start to drive as usua l, the park­
ing brake is automatically released and you r
vehicle begins to move.
When stopp ing at a traff ic signa l or stopp ing
in city traffic, the parking brake can be ap­
plied . The veh icle does not have to be held
with the footbrake. The par king brake elimi­
nates the tendency to c reep with a drive range
engaged. As soon as you dr ive
off as usua l,
the park ing brake is released automatically
and the vehicle starts to move.
Starting on slopes
When sta rt ing on in cl ines, the starting ass ist
p revents the veh icle from uninten tionally ro ll­
ing bac k. The braking force o f the parking
brake is not released un til sufficient dr iving
force has been b uilt up at the whee ls.
(D Tips
For safety reasons, the parking bra ke is re­
l eased automatically only when the driv­
er's safety belt 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 bra ke stays applied
and prevents the vehicle from roll ing back­
ward.
" You can release the switch© once you are
sure that you are developing enough for­
wa rd momentum at the wheels as you de­
press the acce lerator.
Depend ing on the we ight of the rig (vehicle
and trailer) and the severity of the incline, you
may roll backwards as you start. You can p re­
vent rolling backwa rds by holdi ng the par king
brake switch (®) pulled o ut and ac celera ting -
j u st as you wou ld w hen s tarti ng on a hill wi th
a conventiona l hand brake.
Emergency braking
In the event that the conven tional brake sys­
tem fails or locks.
"I n an emergency, pull the switch(®) and
cont inue to pull it to slow your ve hicl e down
w ith the par king b rake.
" As soon as you re lease the swi tch (®) or ac -
celerate, the braking process stops.
If you p ull the swi tc h (®) a nd hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking f unction is initiated. The ve hicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performance
is similar to making an emergency stop¢&..
In order not to activate the emergency brak-
ing by mistake, an audib le warning tone (buz ­
zer) sounds when the switch(®) is pulled. As ..,.

soon as the switch(®) is released, or the accel ­
erator pedal is depressed, emergency braking
stops.
.&_ WARNING
Emergency braking should only be used in
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed .
Using the parking brake to perform emer­
gency braking will slow your vehicle down
as if you had made a full brake applicat ion.
The laws of physics cannot be suspended
even with ESC and its associated compo­
nents (ABS, ASR, EDL). In corners and
when road or weather conditions are bad
'
a full brake application can cause the vehi-
cle to skid or the rear end to break away -
r isking an accident.

Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
are exce edin g the maximum speed that you
have set. You will hear a warning tone when
your speed exceeds the stored value by ap­
proximately 3 mph (3 km/h). An indicator
light. (USA models)/ . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light./.
turns off when the speed decreases be low the
stored maxim um speed.
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you
may want to do so incl ude driving in a co untry
with a general speed limit or if there is a
specified maximum speed for winter tires.
